▼ Liquid lubricants are precluded in an exceedingly large number of consumer as well as extreme applications as a means to reduce friction and wear at the sliding interface of two bodies. The extraterrestrial environment is one such example of an extreme environment which has motivated the development of advanced solid lubricant materials. Mechanical systems for space require fabrication, assembly, transportation and testing on earth before launch and deployment. Solid lubricants for space are expected to not only operate efficiently in the hard vacuum of space but also withstand interactions with moisture or oxygen during the terrestrial storage, transportation and assembly prior to deployment and launch. Molybdenum disulfide (MoS 2 ) is considered the gold standard in solid lubricants for space due to its excellent tribological properties in ultra-high vacuum. However in the presence of environmental species such as water and oxygen or at elevated temperatures, the lubricity and endurance of MoS 2 is severely limited. Past studies have offered several hypotheses for the breakdown of lubrication of MoS2 under the influence of water and oxygen, although exact mechanisms remain unknown. Furthermore, it is unclear if temperature acts as a driver solely for oxidation or for thermally activated slip and thermally activated desorption as well. The answers to these questions are of fundamental importance to improving the reliability of existing MoS 2 -based solid lubricants for space, as well as for guiding the design of advanced lamellar solid lubricant coatings. This dissertation aims to elucidate: (1) the role of water on MoS2 oxidation, (2) the role of water on MoS2 friction, (3) the role of oxygen on MoS2 friction, (4) the contribution of thermal activation to ambient-temperature friction, and (5) effects of length-scale. The results of this study showed that water does not cause oxidation of MoS2 . Water increases ambient-temperature friction of MoS2 directly through a combination of both surface adsorption and diffusion into the coating subsurface. Thermally activated desiccation effectively dries the bulk of the coating, yielding low values of friction coefficient even at ambient humidity and temperature. Friction of MoS 2 decreases with increasing temperature between 25°C and 100°C in the presence of environmental water and increases in the presence of oxygen alone. At temperatures greater than 100°C, friction generally increases with temperature only in the presence of environmental oxygen; at these elevated temperatures, friction decreases with increasing humidity. The transition from room-temperature increase to elevated-temperature decrease in friction with increasing humidity is found to be a strong function of the contact history as well as coating microstructure. Lastly, the contribution of nanoscale tribofilms to macroscale friction was studied through nanotribometry. Friction measured on the worn MoS 2 coating with a nano-scale AFM probe showed direct and quantifiable evidence of sliding-induced surface… Advisors/Committee Members: Burris, David L..

Ph.D. University of Hawaii at Manoa 2011.

The traditional protein disulfide isomerase (PDI) catalyzes the formation, reduction, and isomerization of disulfide bonds of most secretory proteins in the endoplasmic reticulum (ER) of eukaryotes. PDI also serves as a redox-response regulator and chaperone. By modifying disulfide bonds, PDI changes the folded state and activity of its target proteins, which is ultimately important for normal cell metabolism, disease resistance, growth and development. In contrast to animal and yeast PDIs, little information is currently available on the characterization and function of PDIs in plants. The genome of the model plant, Arabidopsis, contains 12 different PDI genes. Some of these have traditional structures very closely related to yeast and mammalian PDIs. However, several differ in the presence of signal peptides, KDEL motifs and the number and positions of thioredoxin domains. In addition, three species of PDIs in plants have transmembrane domains. For PDI antisera generation, immunolocalization, and complementation studies, recombinant expression systems were developed for three PDIs fused to 6X-His to enable purification. For functional studies of PDIs, I mapped and selected homozygous T-DNA knockout lines of the pdi2 (SALK_115574 and SALK _017090), pdi5 (SALK_010645), and pdi8 (SALK _023055) genes by using PCR. The absence of PDI mRNA and proteins were confirmed using RT-PCR and immunoblot analysis. To study protein-protein interactions of PDIs, I identified interacting partners of PDI2 and PDI5 using the yeast two-hybrid system and confirmed their interaction by co-immunoprecipitation, fluorescence resonance energy transfer (FRET), and β-galactosidase assays. PDI5 interacted with three different cysteine protease that played roles in programmed cell death (PCD). PDI2 interacted with several proteins in the secretory pathway as well as nuclear proteins, Rho and MEE8, both of which are transcription factors. To identify the sub-cellular localization of PDIs, PDI2 and PDI8 were transiently expressed as fusion proteins with green fluorescent protein (GFP) in leaf protoplasts. Co-expression with subcellular markers fused to RFP determined that PDI8 localized to the ER and was exported to the vacuole membrane (tonoplast). PDI2 was localized to the ER, Golgi, nucleus, and vacuole. The localizations of PDI2 were confirmed by immunolabeling and transmission electron microscopy.

▼ Sulfur-containing organic solvents or carbon disulfide have been used extensively in semiconductor, TFT-LCD, and synthetic fiber (viscous rayon) industries in the last decades. These compounds can easily be converted into reduced-sulfur ones which exhibit low odor threshold characteristics and arise public complaints once releasing into environments. This paper intended to oxide these compounds by both chemical and biological approaches for the purpose of odor reduction. The first topic was investigations on the oxidation of aqueous DMS (dimethyl sulfide) by using sodium hypochlorite as an oxidant. Results indicated that with an initial DMS concentration of 100 mg/L, it required only 0.75 min or 45 s to convert the DMS completely into its final oxidation product, DMSO2 (dimethyl sulfur dioxide). The required dosage of the oxidant was a little less than the theoretical value. In addition, it was found that initial pH of the batch reaction liquid be kept at around 8.2 for achieving a neutral final solution which emitted only a trace of gaseous chlorine and hydrochloric acid odors. The second one was a trail investigation on the biodegradation of gas-borne hydrogen sulfide and carbon disulfide by a trickling-bed biofilter packed solely with fern chips. Glucose and milk powder were used as main nutrients for microbial film development and enhancer for the biodegradation of sulfides. Results indicated that after an acclimation period of around two months, approximately 99 and 86% of the influent hydrogen sulfide (10-20 ppm) and carbon disulfide (20-60 ppm), respectively, could be removed with an empty bed retention time of around 63 s for the gas in the packed bed. Both neutral or acidic environments were suitable for the biodegradation reaction and the metabolites (mainly, sulfuric acid) could easily be removed from the chips by washing them with water. In the future, efforts should be done to increase the removal capacity of carbon disulfide.

▼ This dissertation tested the hypothesis that pulsed laser deposition (PLD) could be used to create targeted dopant profiles in few layered WS2 films based on congruent evaporation of the target. At the growth temperatures used, 3D Volmer-Weber growth was observed. Increased energy transfer from the PLD plume to the growing films degraded stoichiometry (desorption of sulfur) and mobility. Sulfur vacancies act as donors and produce intrinsic n-type conductivity. Post deposition annealing significantly improved the crystallinity, which was accompanied by a mobility increase from 6.5 to 19.5 cm2/Vs. Preparation conditions that resulted in excess sulfur, possibly in the form of interstitials, resulted in p-type conductivity. Current-voltage studies indicated that Ohmic contacts were governed by surface properties and tunneling. Extrinsic p-type doping of few layered WS2 films with Nb via pulsed laser deposition using ablation targets fabricated from WS2, S and Nb powders is demonstrated. The undoped controls were n-type, and exhibited a Hall mobility of 0.4 cm2/Vs. Films doped at 0.5 and 1.1 atomic percentages niobium were p-type, and characterized by Fermi levels at 0.31 eV and 0.18 eV from the valence band edge. That is, the Fermi level moved closer to the valence band edge with increased doping. With increased Nb doping, the hole concentrations increased from 3.9 x1012 to 8.6 x1013 cm-2, while the mobility decreased from 7.2 to 2.6 cm2/Vs, presumably due to increased ionized impurity scattering. X-ray photoelectron spectroscopy indicates that Nb substitutes on W lattice sites, and the measured peak shifts toward lower binding energy observed corresponded well with the UPS data. Throughout, a clear correlation between degraded stoichiometry and decreased mobility was observed, which indicates that point defect and ionized impurity scattering is a dominant influence on carrier transport in PLD few-layered WS2 films. The approach demonstrates the potential of PLD for targeted doping of transition metal dichalcogenides.

▼ Tez kapsamında, 1 adet SalenH2 tipi disülfit bağı (S−S) içeren sistamin Schiff bazı (1) ve 6 adet orijinal bor kompleksi (2a−2c ve 3a−3c) sentezlendi. Öncelikle salisilaldehitin EtOH'de sistamin dihidroklorür ile tepkimesinden sistamin Schiff bazı (1) elde edildi. Arilboronik asitler (fenilboronik asit ve 4-hidroksifenilboronik asit) ve sistamin Schiff bazı (1), boraksan grubuna (RB-O-BR) sahip dinükleer bor komplekslerini (2a ve 2b) elde etmek için toluende 2:1 sitokiyometride kondenzasyon tepkimesine sokuldu. Boroksin grubuna [(B-O-B)-(O2BPh)] sahip olan ve iki adet dört-koordineli ve bir adet üç koordineli bor atomu içeren trinükleer bor kompleksleri (3a ve 3b), borik asit/aril boronik asit (fenilboronik asit ve 4-hidroksifenilboronik asit) ve sistamin Schiff bazı (1)'in toluende etkileştirilmesi ile sentezlendi. Dinükleer bor kompleksi (2c) ve trinükleer metaborik asit esteri (3c), CH3CN'de sistamin Schiff bazı (1)'in 1 ekivalenti ile borik asitin sırası ile 2 ve 3 ekivalentinden hazırlandı. Bu tezde sentezlenen bor kompleksleri, iki bor atomunu birbirine bağlayan oksijen atomlu merkezi 11-üyeli bir heterohalka içermektedir ve diastereoizomerlerin (mezo ve rasemat) oluşumuna götüren iki stereojenik bor atomuna sahiptir. Yapılar; element analizi, FTIR, MS, 1D 1H, 13C ve 11B NMR ve 2D HSQC yöntemleri ile aydınlatıldı. Dinükleer ve trinükleer bor komplekslerinin antimikrobiyel aktivitesi, beş bakteriye karşı incelendi. Dinükleer (2b) ve trinükleer (3b) bor komplekslerinin bakteriler üzerinde antimikrobiyel etkiye sahip olduğu ve sistamin Schiff bazı (1), dinükleer (2a ve 2c) ve trinükleer (3a ve 3c) bor komplekslerinin test edilen suşlara karşı zayıf antimikrobiyel aktivite gösterdiği görüldü. Bununla birlikte, bu tezde sentezlenen bor komplekslerinin pBR322 plasmid DNA, calf thymus DNA ve somon sperm dsDNA ile etkileşimi, agaroz jel elektroforez ile ve spektrofotometrik olarak incelendi. Sonuçlar, sistamin Schiff bazı (1) ve dinükleer (2a−2c) ve trinükleer (3a−3c) bor komplekslerinin dsDNA ile etkileştiğini gösterdi. Sistamin Schiff bazı (1), dinükleer (2a−2c) ve trinükleer (3a) bor komplekslerinin dsDNA ile interkelasyon yaparak ve trinükleer bor kompleksleri (3b ve 3c)'nin dsDNA ile hem oluk hem de interkalasyon yolu ile etkileştiği bulundu. Within the contex of this thesis, 1 SalenH2 type ligand with disulphide bond (S−S), cystamine Schiff base (1), and 6 original boron complexes (2a−2c and 3a−3c) were synthesized. Firstly, cystamine Schiff base (1) was obtained from the reaction of salicylaldehyde with cystamine dihydrochloride in EtOH. Arylboronic acids (phenylboronic acid and 4-hydroxyphenylboronic acid) and cystamine Schiff base (1) were brought to condensation reactions in a 2:1 stoichiometry in toluene to obtain dinuclear boron complexes with a boraxane group (RB-O-BR) (2a and 2b). Trinuclear boron complexes (3a and 3b) with a boroxine group (B-O-B)-(O2BPh), two four-coordinate and one three-coordinate boron atoms were synthesized through the combination of boric acid/arylboronic acid (phenylboronic… Advisors/Committee Members: Koçak, Selen Bilge (advisor).

▼ This thesis has a research focus on novel nanomaterials synthesis, fabrication and the fundamental understanding of the process and properties regarding surface enhanced Raman spectroscopy application. The two projects are: 1) a novel solid-state growth of silver nanowires (AgNWs), and 2) fabrication of 2D layered MoS2 on gold film for surface enhanced Raman spectroscopy (SERS). Solid-state and bottom-up growth of nanowires-based research has been specific to semi-conductor nanowires, with rare research reports on the growth of metal nanowires in the similar manner. Synthesis of AgNWs has been around in the research filed for more than a decade. Most of the synthesis processes reported till now were all solution-based processes involving complex synthesis set-up employing harsh conditions for good yield. This research presents a solid-state green synthesis of AgNWs with detailed growth analysis, reporting key factors influencing the self-growth of the nanowires. Our synthesis process is simple, performed at room temperatures and uses bio-compatible chitosan polymer as base for silver nanoparticles (AgNPs) synthesis and AgNWs growth. A new way of blocking oxygen by thin film coating, to avoid oxidative etching of Ag atoms which hinders growth of AgNWs, is investigated. Role of Cl- ions and influence of its concentration to initiate the growth AgNWs is examined thoroughly with the help of UV-Vis, XRD and EDS analysis. Finally, role of time in the continuous growth of AgNWs is studied for seven weeks long under SEM. AgNWs/Chitosan polymer platform is directly employed in SERS application to detect Raman active probe Rhodamine 6G (R6G) at a detection limit of 10-7M. This report, for the first time, presents an inexpensive synthetic and growth mechanism for solid-state and bottom-up growth of metal nanowires. This research helps in paving a new way for research involved with Ag nanowires. 2D materials other than graphene which made their presence strong in research field are transition metal dichalcogenides (TMDCs). Among a range of TMD materials, Molybdenum disulfide (MoS2) has shown promising impact in various fields like optoelectronics, SERS based biosensors, photonics and electrochemistry. SERS enhancement observed in semiconductor (1.8ev) monolayer MoS2 is due to various factors like surface plasmons, excitons and charge transfer. But, monolayer MoS2 exhibit a modest Raman enhancement (<100) when compared to other 2D materials like graphene. Multilayer MoS2 which have lower bandgap (1.4ev to 1.6ev) exhibits no SERS enhancement due to increase in the thickness of the material. Lower SERS enhancement property of monolayer MoS2 is addressed by incorporation of nanoparticles on the surface of MoS2 and with the combination of MoS2 and metal nanostructures. But, there are very less reports on dealing with few layers MoS2 SERS enhancement. Here, in this report we observed raise in intensity of primary Raman signals E2g1 and A1g of few layer MoS2 with respect to change in thickness of Au film substrates on which MoS2 is…

▼ Nano materials such as nanowires and 2-dimensional (2-D) molybdenum disulfide (MoS2) have received tremendous attention over the past few decades. Numerous applications have been proposed such as nanowire MOSFETs, nanowire electrical generators, nanowire biosensors, nanowire single photon detectors, MoS2 transistors, and MoS2 photodetectors. Some of these devices outperform state-of-the-art commercial products, but none of these nano material based devices have been commercialized up to date. One of the biggest barriers for industries to use these nano materials is a lack of mass fabrications methods. For nanowires, obtaining a large area planar array of nanowires is extremely difficult and no known method can achieve a high-density large-area array of precisely positioned nanowires. Although there has been huge progress over the past few years, the yield and density of planar nanowire arrays from the reported literature are far from required values for industrial use. For MoS2, obtaining a single-crystal phase with a wafer-scale uniform monolayer is needed in order for the material to be mass fabricated. Although wafer scale monolayer MoS2 has successfully been grown, it contained a high density of grain boundaries which would cause non-uniform performance when mass produced into nano-scale devices. In this dissertation, general pathways for commercialization of nanowire and MoS2 based devices will be explained as well as the backgrounds on the nanowire/MoS2 field. Also, state-of the art methods for achieving planar nanowire arrays and growing monolayer MoS2 will be discussed. In a later section, a new method will be proposed that shows the highest yield and density of planar nanowires ever reported. A growth method for obtaining large-scale single-crystal monolayer MoS2 will be proposed as well. Advisors/Committee Members: Li, Xiuling (advisor), Li, Xiuling (Committee Chair), Lyding, Joseph W.

▼ In the past few decades, there has been a tremendous ongoing effort to understand the nature of nanomaterials. Shrinking dimensions of the materials to the nanoscale regime reveal various intriguing properties of the nanomaterials due to quantum confinement effects. Especially, electron confinement in two dimensional materials enables compelling electronic properties as compared to the other nanostructured materials. Besides, thinning 2D materials down to monolayer thicknesses increases the surface-to-volume ratio to such an extent that makes them appealing for electrochemical energy conversion and storage technologies. Moreover, atomically thin 2D materials are flexible with good performance under bending, making them attractive materials for flexible electronics, energy storage devices and actuators. Recent advancements in energy storage technologies using 2D materials, particularly in materials such as graphene and its analogues, would finally make supercapacitors viable to complement or replace batteries. High surface-to-volume ratio and good ionic transport in addition to excellent electrical conductivity enables high charge storage capacities with fast energy uptake and delivery. For instance, graphene possess very high capacitive charge storage performance thanks to pure electrostatic attraction of ions (electrochemical double layer effect) on the highly porous carbon surface. Besides, pseudocapacitive 2D materials such as transition metal carbides (Mxenes) possess good electrical conductivity and capacitive performance concurrently because of the presence of transition metal in the structure. Transition metal dichalcogenides (LTMDs) such as molybdenum disulphide (MoS2) are also studied candidate materials for electrochemical charge storage as well. However, naturally occurring MoS2 has a 2H phase crystal structure with 1.9 eV band gap, which renders it semi-insulating and therefore not immediately attractive as an electrode material for energy storage. Despite, the 1T phase of MoS2 is metallic and 107 time more conductive that 2H phase. The aim of this work is to use the metallic 1T phase of MoS2, which can be obtained from the semiconducting 2H phase of MoS2 during chemical exfoliation of the bulk material. In so doing, the ultimate goal is to exploit the phase transformation of MoS2 and successfully utilize it as supercapacitor electrode. The results show that that chemically exfoliated nanosheets of MoS2 containing a high concentration of the metallic 1T phase can electrochemically intercalate ions such as H+ , Li+ , Na+ and K+ with extraordinary efficiency and achieve capacitance values ranging from âˆ¼400 to âˆ¼700 F cmâˆ’3 in a variety of aqueous electrolytes. We also demonstrate that this material is suitable for high-voltage operation in non-aqueous organic electrolytes, showing prime volumetric energy and power density values, coulombic efficiencies in excess of 95%, and stability over 5,000 cycles. As we show by X-ray diffraction analysis, these favourable electrochemical properties of 1T MoS2… Advisors/Committee Members: Chhowalla, Manish (chair), Klein, Lisa (internal member), Amatucci, Glenn (internal member), Akdogan, Koray (internal member), Asefa, Tewodros (outside member).

Two dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) have attracted much attention due to their unique physical and chemical properties. Increased interest in the research of 2D layered materials began in 2004 when graphene, a monolayer of graphite, was discovered. TMDs are a class of layered materials which consist of over 40 members ranging from semiconductors to insulator to metals. There are three polytypes crystal structure of TMDs (1T, 2H, and 3R), which represent trigonal, hexagonal and rhombohedral, respectively. TMDs can be synthesized by one of two different approaches, top-down and bottom-up. Top-down includes mechanical and chemical exfoliation, while bottom-up includes physical and chemical vapor deposition. Synthesizing these atomically thin materials enables a new set of properties due to the quantum confinement effects. MoS2 and NbS2 are two significant members of the TMD family and are the main topic of work in this thesis. These two materials were successfully synthesized with chemical vapor deposition (CVD) by controlling their growth parameters, each of which has a great influence on nucleation and the growth mechanism. Their shape evolution mechanism provides important insight into their nucleation and growth mechanism. The MoS2 part of this work was dedicated to understand this mechanism and how to apply it to other TMDs. To do that, MoS2 was synthesized on different substrates to explore the optimum surface chemistry between the substrate atoms and reactants. On the other hand, Niobium disulfide (NbS2) has received less attention compared to other TMDS due to its unexplored properties. Therefore, analyzing growth parameters and the potential applications of NbS2 was also another aim of this thesis. In the NbS2 part of this thesis, two different approaches were pursued growing NbS2 flakes. The first approach used sulfur and Nb2O5 powders as the precursors. The second approach used an alkali promoter, Nb2O5, and sulfur. The alkali-assisted approach yielded high-quality growth of few-layered NbS2 with thicknesses ranging from 2 – 10 nm and lateral dimensions in the hundreds of micrometers. Our Raman and transmission electron microscopy analyses suggested that the as-grown material is a mixture of 2H and 3R phases. It was found that there was a substantial amount of incorporated potassium ions from the growth process in the NbS2 samples, which leads to doping and metallic behavior. In the absence of alkali growth promoters, the lateral dimensions of the crystals are smaller, but they displayed metallic behavior. The electrical and HER properties of NbS2 exhibited a promising result for future studies. The realization of thin and metallic TMDs is crucial for studying potential integration into electronics and catalysis.

▼ This report describes a kinetic study of the thermal decomposition of methyl disulfide. The study was made as a contribution to the chemistry of organic sulfur compounds. The homogeneous decomposition was studied by the static method in an all-glass apparatus. It was followed by observation of the accompanying pressure changes and by analysis of the reaction mixture at various stages of the reaction. Several new analytical methods were developed for this analysis. The experimental conditions were varied by varying the temperature of the decomposition, the pressure of the reactant, and the surface to volume ratio of the reaction vessel, and by adding various substances to the reacting system. The experimental results show that the reaction is composite: (1) Initially a fraction of the reactant disulfide adsorbs on the surface of the pyrex reaction vessel at a rate which agrees with the theoretical rate for a collision mechanism. (2) There follows an induction period during which the disulfide does not decompose. (3) The first decomposition is into methyl mercap-tan and a non-volatile product believed to be a thiofor-maldehyde polymer. The suggested overall reactions are: CH₃-S-S-CH₃ → CH₃SH + CH₂=S n CH₂=S → (-CH₂-S-)n (4) A later, competing, process produces hydrogen sulfide, ethylene, free sulfur and polysulfides. It is possible that the carbon disulfide formed is produced by this reaction, and it is probable that the thioaldehyde polymer is decomposed. The overall unbalanced reactions may be written: CH₃SSCH₃ + ((CH₂S)n?) → H₂S + C₂H₄ + S + (CS₂?) + (?) CH₃-S-S-CH₃ + Sₓ → CH₃-Sₓ -CH₃ (5) Secondary reactions continue long after the disulphide has been used up. The major process appears to be the degradation of the postulated polythioformaldehyde to hydrogen sulfide and possibly to carbon disulfide and ethylene. Degradation of the polysulfides appears to occur also, and there may well be further secondary reactions. The nature of the various component processes have been discussed in some detail, and lines of further research have been suggested. The structure of disulfides and polysulfides and the bonding of organic sulfur compounds have been discussed.

There has been an increased interest in the research of 2D layered materials since the past few years especially after the discovery and physics related study of Graphene, a monolayer of graphite. Layered materials beyond graphene are the family of transition metal dichalcogenides (TMDs) which consist of over 40 members ranging from semiconductors to insulators to metals. All these materials are shown to be easily exfoliated to form monolayers which exhibit a new set of properties owing to the quantum confinement effects that occur during their exfoliation. The intrinsic thickness of less than 1nm per layer, lack of dangling bonds, controllable bandgap and precise control of thickness has aroused the interest of electrical engineers all over the world to use these materials for future electronics and make the dream of all 2D electronics to become true. Field effect transistors made from TMD semiconductors (MoS2, WS2, MoSe2, WSe2 etc.) are exhibiting excellent characteristics namely ON/OFF ratios in the range of 108, saturation currents exceeding 200 μA/μm, mobilities exceeding 100 cm2/Vs and subthreshold swings almost approaching the theoretical limit of 60 mV/dec. Though these values are impressive, they are far below their theoretical expectations, mainly due to the high contact resistance between the metal and semiconductor because of which their excellent intrinsic characteristics are not practically realized. There have been many efforts in mitigating this high contact resistance such as use of different contact metals, chemical doping of contact regions and long thermal annealing of devices which resulted in partial success. The aim of this work would be in establishing a universal strategy in reducing this high contact resistance to provide an ohmic-like contact between the metal and the TMD semiconductor by employing their phase-engineered metallic counterparts as the contacts. By fabricating transistors in which the electrode material and the channel similar is of the same material composition, many factors, which are detrimental to the operation of high performance transistors, can be eliminated. We have gained expertise in phase transformation of these transition metal dichalcogenides and successful utilized them as the contacts by locally patterning different phases on a single monolayer flake. We obtained record saturation currents, transconductances, mobilities and sub-threshold slopes for our novel transistors. This thesis will include details of synthesis of these TMD semiconductors, phase transformation and fabrication of transistors with lowered contact resistance with main emphasis on Molybdenum disulfide (MoS2).

▼ In the General Introduction to this Thesis, it was pointed out that the work of previous investigators posed two major problems. The first of these is that of the two “missing” sulfur atoms, and the second, that of the chemical nature of the “active site” of papain. The results of the present investigation provide the answer to the first of these two problems. The investigation of the sulfhydryl content of native, unactivated papain by a number of methods reveals only a fraction of a mole of sulfhydryl per mole of protein. The disulfide interchange reaction clearly indicates the presence of eight groups of papain which, after exposure to 9.6N HC1 at 39°, behave in a manner analogous to the cysteine and cysteine residues in other proteins. In fact, it appears to be reasonable to assume that under the conditions of the interchange reaction, we are dealing with eight half-cystine residues. The determination of the disulfide content of papain by argentimetric amperometric titration with sulfite as the cleaving agent clearly shows the presence of three disulfide bonds in papain at near-neutral pH, whether in the native, urea-denatured, or detergent denatured protein. When papain is exposed to pH 1.7 for a short period of time and then titrated at near-neutral pH in 8M urea, four disulfide bonds may be titrated with silver ion in presence of sulfite. Finally, determination of cysteic acid in acid hydrolysates of papain oxidized with preformic acid clearly shows the presence of eight moles of cysteic acid per mole of papain. The above evidence indicates that after acid treatment or oxidation (which is also performed under acidic conditions), the sulfur content of papain can be accounted for completely on the basis of the half-cystine content of the protein. The answer to the first of the two problems posed above unfortunately has not automatically provided an answer to the second. The studies on the thiol content of active papain in clearly indicate that the activation of papain is associated with the appearance of on thiol group per mole of protein. The hypothesis that activation of papain involves the cleavage of a disulfide bond is subject to a number of serious criticisms. 1. A reductive cleavage of an intramolecular disulfide by column reduction should lead to the appearance of two thiol groups. Actually, Finkle and Smith have shown that only one such group appears as a result of this treatment. This point has been confirmed in the present study. 2. The assumption of an inter-molecular disulfide bond requires the concomitant assumption that inactive papain is a dimer. No evidence for the existence of such a dimer has been found. 3. The fact that acid treatment is required before the fourth disulfide bond can be titrated with silver ion in the presence of sulfite is plausibly explained on the basis of the simple assumption that the denaturation resulting from this treatment renders the bond accessible to sulfite, or changes its environment. The finding that 8M urea at 37° does not bring this about argues against this…

▼ MoS2 nanosheets (MoS2 NSs) have been shown in past publication having various advantages: easily uptake by cells, surface modification of functional groups and low cytotoxicity, with high degradability (in vivo). In recent studies, in order to increase the dispersion of MoS2 nanosheets in water, the molecules used as dispersions have evolved from commercial surfactants to biomolecules, such as lysozymes, bovine serum albumin, silk fibroin, etc., which are suitable for organisms. This phenomenon shows that the MoS2 nanosheets have a strong affinity for the peptide molecules in vivo. Amyloid diseases: including Alzheimer's, Parkinson's and type 2 diabetes each have their own pathologies associated with specific amyloidogenic peptides or proteins. The fibrosis of each of these peptides involves complex multi-steps. The process changes from monomeric form to soluble oligomers and fibril or amyloid seed until eventually large hydrophobic mature fibrils are formed. Current research supports low molecular weight soluble oligomers as an intermediate species in the aggregation pathway that ultimately contributes to amyloid-mediated cell death. Therefore, many studies using small molecule drugs or nanomaterials to control amyloid inhibition have flourished. As described in the previous paragraph, this study performed a series of studies on the affinity between molybdenum disulfide nanosheets and bovine insulin, and the regulation of bovine insulin aggregation. The theoretical calculation of affinity shows that the negatively charged and hydrophobic nature of MoS2 nanosheets surface facilitates the adsorption of positively charged and hydrophobic amino acids. Different sizes of molybdenum disulfide nanoparticles were prepared at different ultrasonic oscillation times, and the best size was selected in experiments that inhibit bovine insulin aggregation. Finally, it is concluded that the MoS2 nanosheets help to reduce the formation of bovine insulin fibers and reduce the resulting hemolytic effects, will expand the application value of MoS2 nanosheets in biochemistry.

▼ There is a rising demand to substitute fossil fuels with environmental-friendly energy resources. Providing hydrogen resource through a water splitting process can be one way to satisfy this critical need. The high cost of the conventional water splitting catalysts such as platinum makes this process inapplicable for industry utilization. Hence, there is a need to find low cost catalysts to make this process applicable for future applications. In this respect, earth abundant and inexpensive MoS2 nanostructures with sulfur (s) terminated edge atoms have previously been tested for HER activity. However, results indicate less efficient HERs on these structures which is mainly attributed to: (i) a low electrochemical activity of sulfur edge atoms, and (ii) a high charge transfer resistance between semiconductor MoS2 and electrode due to the Schottky barrier formation at their interface. In this work, a large-area crystalline 3D structured MoS2/Graphene (Gr) heterostructure is directly grown on the glass carbon electrodes using a large-scale atmospheric pressure chemical vapor deposition (APCVD) technique to considerably increase the active edge atoms of the MoS2 and improve the charge transfer toward active edge sites. The grown 3D structured MoS2 with Mo terminated edges has shown remarkable electrochemical activity due to the high density of d orbital electrons of the edge atoms (Mo). Our recent work published in chemistry of materials[1], which is widely reviewed in the second and third chapters of this dissertation, has fully investigated the growth mechanisms of this structure and the applicability of its heterostructure with graphene for HER activity. The control experiments and characterizations have revealed that the 3D structured MoS2 follows the Stranski-Krastanov growth mode in which the transition from 2D to 3D happens after a critical thickness. The turn over frequency (TOF) measurements have shown a very high value for the 3D structured MoS2 demonstrating high chemical activity of this structure. Also, the electrochemical impedance spectroscopy (EIS) measurements have shown that the charge transfer resistance is much lower in 3D structured MoS2 grown on graphene film than those grown on glassy carbon and transferred to glassy carbon. These results confirm that the growth of this structure on top of the graphene film considerably improved the contact resistance between MoS2 and electrode.

▼ Atomic thin transition metal dichalcogenides (TMDCs) are a large class of low dimensional materials, having many unique properties such as indirect-direct band gap transition, strong spin-orbit coupling, valence band maximum (VBM) and conductance band minimum (CBM) at the corners of the Brillouin zone for monolayer TMDCs, and conservation of spatial symmetry or broken symmetry depending on the number of layers. The photoluminescence (PL) and Raman spectra can be used to effectively detect the small variations in the atomic and energy band structure of monolayer and multilayer TMDCs. This study thoroughly investigates the PL and Raman spectra of atomic thin MoS₂ and WS₂. Many second-order Raman vibrational modes assisted by defects have been observed in the Raman spectrum, under 514.5 nm (corresponding to 2.40 eV) excitation. The frequencies of the 2LA(M), A_1g(M) + LA(M) and 2LA(M) ‒ 2E_2g¹(M) modes are 352, 582 and 297cm^-1, respectively. LA(M) refers to the longitudinal acoustic mode around point M in the Brillouin zone. Monolayer TMDCs such as WS₂ are direct band gap semiconductors. Exciton is formed by the hole and electron at the VBM and CBM, respectively. The recombination energy of A exciton in monolayer WS₂ varies from 2.053 eV at 77 K to 2.01eV at room temperature. The direct band gap at point K decreases with increasing temperature due to electron-phonon coupling. The chemical bonding weakens with enhanced vibration of lattice, which increases the energy band gap. The relation between band gap and temperature is fitted and the energy band gap at absolute temperature is 2.057 eV, which is consistent with the density functional theory (DFT) calculation. Bilayer TMDCs such as WS₂ and MoS₂ are indirect band gap semiconductors. The indirect band gap in bilayer MoS₂ is 1.50 eV, whereas that in the hexagonal boron nitride(hBN)-encapsulated bilayer is 1.52 eV. The variation in indirect band gap is due to the sensitivity of the VBM at the Γ point. The indirect band gap of trilayer TMDCs is 1.47 eV. The emerging indirect energy gap in a heterostructure with monolayer WS₂ and MoS₂ is caused by the hybridization of the Γ point in the two layers. The extent of hybridization is determined by the interlayer distance, which can be varied with the time of annealing at 393K. The interlayer distance varies from 1.6 to 0.8 nm after 12 h of annealing. The indirect band gap emerges at 1.79 eV after 6 h of annealing and shifts down to 1.4 eV after 12 h of annealing. The biaxial tensile strain in the hBN-encapsulated multilayer MoS₂ induced by annealing at 600 K can be detected by the redshift of E_2g¹ in the Raman spectra, which is consistent with the DFT calculation. The redshift of the in-plane mode, E_2g¹, is 1.57 cm^-1 and the blueshift of the out-of-plane mode, A_1g, is 0.28cm^-1. For the hBN-encapsulated…

▼ This thesis mainly focuses on the fabrication and transport measurement of three different materials: two-dimensional (2D) MoS₂ and germanane, and one-dimensional (1D) carbon nanotube. In MoS₂ electrical double layer transistor, artificial hetero states are induced at the top and bottom surface of a single few-layer flake, forming a homojunction with atomically sharp and clean interface. The doping level of the top and bottom surface are controlled by ionic gating and back gating, where superconductivity and Shubnikov-de Haas quantum oscillation is observed, respectively. The interaction between these two states can be electrically tuned between weak and strong coupling. Phenomenologically, an insulating bottom surface serves as an additional dielectric layer for the carrier tuning of top superconducting channel by back gating, while a conducting bottom channel causes anti-proximity effect between top and bottom surface which suppress the superconductivity in top channel. Furthermore, a lateral superconductor-normal-superconductor junction is realized at the surface of MoS₂ by partially isolating the surface from ionic liquid. An anomalous magnetoresistance is observed, which is attributed to the non-monotonic behavior probability of Andreev reflection with the increase of magnetic field. Germanane (GeH) transistor is fabricated for studying its electronic properties. Due to its large band gap nature, the as-made GeH transistor shows little conductivity. After thermal annealing, however, the conductivity is greatly improved, and the conductivity increases with increasing annealing temperature. Eventually a metallic state is established, showing very high conductivity which is comparable to metal and higher than any allotrope of germanium. Combined with the Raman spectra, we argue that the enhancement of conductivity is dominated by the dehydrogenation. During annealing, hydrogen atoms escape from the framework of GeH, leaving behind the multi-layer germanene. Weak antilocalization is observed at low temperature, suggesting that the spin-orbit interaction is strong in multi-layer gemanene. Ultra-small (0.4 nm) single-walled carbon nanotubes (SWCNTs) are synthesized in the linear channels of AFI zeolite crystal. An efficient CVD process of growing uniform 0.4 nm-SWCNTs using ethylene and CO is developed. From the Raman spectra, both the RBM and G band are clearer and stronger than the old process which use the template molecules as the carbon source for growing SWCNTs. The two clear RBM peaks at 535 and 551 cm^-1 indicate that the 0.4 [email protected] are mainly composed of (5,0) and (3,3) nanotubes. This conclusion is supported by theoretical simulation of the RBM. By using ethylene as the carbon feedstock, the optimal conditions are found to be heating under high pressure with a temperature of 700°C, both the quantity and quality of 0.4 nm-SWCNTs in the AFI channels are significantly improved.

▼ Basal-bolus insulin therapy is essential for maintaining tight glycemic control in patients with type 1 diabetes. Despite recent advances, there are issues with its long-term heat stability, which particularly affects patients living in poorer tropical regions. Hence there is a need to develop more thermally stable analogues of insulin. Some degradation products are caused by disulfide shuffling which leads to oligomerization. This could be avoided by substituting the disulfide bonds with non-reducible cystine isosteres such as cystathionine, but incorporation of non-natural mimetics in peptides generally requires chemical synthesis. All current insulin therapeutics on the market are produced biosynthetically due to the large mass of material required and there are currently no chemical methods available that rival these yields. A more efficient chemical synthesis is required to make a modified analogue viable. Described herein are three key accomplishments which attempt to address the issues raised above. Firstly, an improved method for forming disulfide bonds in peptides utilizing a photocleavable thiol protecting group in combination with an “activated” thiol is reported. The efficacy of this new approach was established in simpler model systems and then applied to insulin, whereby higher yields were achieved compared to existing synthetic methods. Secondly, a proof-of-concept study was designed such that lactam bridges were incorporated into insulin-like peptide 3 as replacements for the intermolecular disulfide bonds. The insights gained from this study helped formulate new approaches for incorporating non-natural mimetics in insulin. Finally, replacement of the A6 – A11 disulfide bond with cystathionine in insulin was achieved via the use of orthogonally-protected monomeric building blocks. This new analogue was synthesized in excellent yield and has been fully characterized. It was found to have native binding activity for both insulin receptors and a tertiary structure similar to human insulin. Its serum stability was maintained and it exhibited improved thermal stability, which could lead to an enhanced therapeutic.
