▼ Liquids display an astonishing array of phenomena that, at first glance, seem to have little in common. In this thesis, we study two of these phenomena. The first is the hydrophobic effect, the well-known tendency of oil and water to demix and the driving force for biological assembly. The second is the glass transition, the process by which liquids cooled to very low temperatures become increasingly viscous until succumbing to structural arrest and displaying the rigidity of a solid with none of its microscopic ordering.In the first part of this thesis, we expand upon our prior understanding of the hydrophobic effect. We study the behavior of water in the confined volume created by a pair of RNA helices at the inter-subunit interface of the bacterial ribosome, which provides an opportunity to apply our contemporary understanding of the hydrophobic effect, first detailed by Lum, Chandler, and Weeks almost twenty years ago, to a context that is less idealized than previously studied. We also discuss and improve upon computational models of hydrophobic solvation, expanding their applicability to more complicated solute geometries.In the second part of this thesis, we study the glass transition from the perspective of the East model, a kinetically constrained lattice model of glass formers. We review and derive a number of results for East model glasses that we expect to emerge in more realistic, atomistic models of glass formers. We choose one such model and drive it out of equilibrium by cooling, forming a glass. We then check whether our East model predictions are correct. Of particular interest to us is whether inter-excitation correlations emerge out of equilibrium, a key prediction of the East model. Our atomistic results suggest that they do not, forcing us to reconsider our conceptual mapping between the highly abstract East model and more realistic models of glass formers.The common thread in these seemingly disparate parts of the thesis is the importance of collective fluctuations in liquid-state phenomena. The hydrophobic effect is a physical consequence of liquid-vapor interfacial fluctuations near extended hydrophobic surfaces, while dynamics in supercooled liquids, the precursors to glasses, are dominated by small, collective motions of particles in an otherwise jammed material. The importance of fluctuations in these and other liquid-state phenomena make the tools of statistical mechanics particularly suitable to their study. In this thesis, we employ these tools in the service of furthering our understanding of the liquid state.

▼ In the first part of this thesis, I discuss my work on droplet growth kinetics during dropwise condensation. Accurate heat transfer predictions during dropwise condensation depend on the growth rates of the condensing droplets. This includes both the heat transfer rate during droplet growth as well as following droplet sweeping—where large droplets sweep away other droplets on an inclined surface. Droplet growth rates on a given surface primarily depend on background vapor pressure and the extent of wall subcooling. Here, I report that larger droplets affect the growth rates of nearby smaller droplets during dropwise condensation on superhydrophobic aluminum surfaces. In large systems, neglecting this influence is less of a concern as the error will largely be contained in the uncertainty of the heat transfer rate prediction. However, in smaller phase-change heat transfer systems, like those currently being explored to cool MEMS/NEMS devices, accurate predictions of droplet growth rates are crucial. In this work, using high-angle environmental scanning electron microscopy (ESEM), I report visualizations of the effect that larger droplets have on the growth rates of nearby smaller droplets. Furthermore, I also hypothesize the underlying mechanism behind this phenomenon and discuss my ongoing work to validate this hypothesis. In the second part of this thesis, I propose a project to use functionalized surfaces to combat contamination of low-emissivity cryogenic surfaces. Future crewed space missions require high capacity cryocoolers for zero boil-off (ZBO) systems. Due to parasitic heat loads, cryocoolers have low efficiency, making approaches to limiting these loads highly desired. Water cryodepositing onto low-emissivity cryogenic surfaces results in high parasitic radiative loads. In this project, I propose a method for combating this load increase. Specifically, I propose to use a functionalized (biphilic) surface to getter water onto a small percentage (< 5 %) of the cryogenic surface, thus maintaining an overall low-emissivity. I aim to determine whether (1) the spatial control of water nucleation that the biphilic surface exhibits in non-cryogenic conditions extend to cryogenic conditions, (2) the biphilic surface maintains the low-emissivity of the cryogenic surface, and (3) the biphilic surface is durable in space-cryocooler applications. I discuss the preliminary considerations and objectives for this work, including the proposed fabrication and characterization process for the biphilic surfaces, as well as the proposed experimental apparatus to be used in conducting experiments.

▼ Using both artificial and natural templates, biomimetic micro-structures are fabricated on conventional coating materials (epoxy and silicone elastomers) to mimic both artificial and natural templates through effective pattern transfer processes. The pattern transfer processes use a soft-polymer negative stamp, where the flexibility of the stamp allows for easy conformation to both flat and curved surfaces. Patterns have been successfully transferred as a rigid epoxy to complex surfaces or as a soft elastomer replica of a hydrophobic Trembling Aspen leaf. The hydrophobicity and friction behaviour of the resulting micro-patterned surfaces are systematically investigated, showing that surface patterning can be used as an effective way to improve hydrophobicity while reducing the surface adhesion and friction without a loss of the structural integrity or rigidity typical of epoxy coatings. The relative strength of the micro-pattern was determined through indentation testing in order to support the claim of a robust pattern on the micro-scale that is able to withstand the harsh environment of industrial application or weather exposure. With the well characterized patterned epoxy material fabricated and able to be transferred to many different surfaces, the potential for the patterned surface to act as an icephobic coating was pursued. The robustness of the epoxy material with the unique ability to coat surfaces that are typically unable to possess a micro-structure makes this coating an ideal candidate for large-scale icephobic application. The potential use of a micro-patterned epoxy coating is investigated against comparable surface coatings within an innovative experimental set-up to measure the relative ice-adhesion strength of different substrates. In characterizing the relative shear-force required to remove frozen water droplets from the coating surface at the interface, several variables and factors were explored. The addition of a surface pattern was found to impact the icephobic ability of several materials, where different materials with the same pattern were compared to identify that the surface energy of the substrate influences the icephobic nature of a surface. Moreover, previous studies that relate the water contact angle or hysteresis to ice-adhesion strength are questioned through a preliminary qualitative analysis of ice adhesion strength data. This work demonstrates a potential process for the utilization of biomimetic epoxy micro-patterns as an enhanced hydrophobic and icephobic option for large scale protective coatings.

Istraživanja u okviru ove doktorske disertacije sprovedena su sa osnovnim ciljem razvoja derivata pektina unapređene funkcionalnosti u odnosu na primenu ovog polisaharida kao sorbenta i materijala za izradu ambalažnih filmova. U prvom delu rada opisan je postupak modifikacije pektina u reakciji esterifikacije sa acil-dihloridima, nakon čega su ispitana svojstva dobijenih acilovanih derivata sintetisanih pri različitim molarnim odnosima agensa za acilaciju i galakturonske kiseline. Utvrđeno je da promene u strukturi utiču na reološka, termička i morfološka svojstva pektina, kao i na interakcije koje se uspostavljaju u vodenim rastvorima. U cilju detaljnog sagledavanja svih parametara koji mogu imati uticaj na sorpciju pektina i njegovih derivata, u drugom delu rada ispitan je uticaj specifičnih anjona na umrežavanje nativnog pektina u vodenim rastvorima soli bakra. Analiza ovog uticaja rezultovala je uspostavljanjem analogije umrežavanja pektina sa relativnim uticajem anjona u vodenim rastvorima koje je opisano Hofmeister-ovom teorijom. Hidrofobnost acilovanih derivata, kao i mogućnost njihove primene kao sorbenata i materijala za izradu ambalažnih filmova, ispitana je u trećem delu rada. Dobijeni rezultati ukazuju da acil ostaci (C4-C10) u strukturi derivata utiču na povećanje hidrofobnosti nativnog pektina, što se može smatrati jednim od najznačajnijih rezultata proisteklih iz ove disertacije. Parametri procesa sorpcije Cu2+ jona iz vodenih rastvora ukazuju da acilovani derivati poseduju manji ravnotežni kapacitet u poređenju sa nativnim pektinom, pri čemu je utvrđeno da je vrednost ovog parametra uslovljena strukturom derivata. Filmovi na bazi acilovanih derivata pektina predstavljaju bolju barijeru za transport vodene pare, što se tumači kao posledica njihove povećane hidrofobnosti. Ipak, rezultati mehaničkih ispitivanja ukazuju da predložene modifikacije nemaju pozitivan uticaj na moguću primenu sintetisanih derivata kao materijala za izradu ambalažnih filmova.

Coacervation exhibits promising applications in various fields due to its unique properties. Proteins, a common polyelectrolyte, are known to form coacervate phases. As protein are complex macromolecules with multiple different hydrophobic and hydrophilic repeat units, it was hypothesized that the hydrophobic units may broaden the composition window for coacervation as at non-stoichiometric charge ratios hydrophobic groups can associate to stabilize phase separated structures similar to ion-pair interactions. Therefore, a simple synthetic system was investigated to isolate the influence of hydrophobic groups on the phase behavior of an aqueous polyelectrolyte blend. The objective of this work was to investigate if hydrophobically modify poly (methacrylic acid), a synthetic polyelectrolyte, was able to expand the composition window of the coacervate phase. In this work, a series of hydrophobically modified poly (methacrylic acid) and poly (allylamine hydrochloride) were investigated as negatively and positive charged polyelectrolytes, respectively. Poly (methacrylic acid), poly (methacrylic acid)-co-poly (methyl acrylate) and poly (methacrylic acid)-co-poly (ethyl acrylate) and poly (methacrylic acid)-co-poly (isopropyl acrylate) were synthesized by free radical polymerization. The target molar ratio was 9:1, where the hydrophobic acrylate part accounts for 10 mol% of the backbone repeat units. Nuclear magnetic resonance (NMR) was used to characterize the composition of the synthesized polymer. Gel permeation chromatography (GPC) was utilized to determine the molecular weight of the synthesized polymer. The phase separation and coacervate complex formation of poly (methacrylic acid) (PMAA) or its copolymers with poly (allylamine hydrochloride) (PAH) were investigated as a function of salt concentration. Sample turbidity is considered as an indicator of coacervate formation. By comparing the phase behavior plot, the precipitation region broadens with increasing salt concentration. By increasing the hydrophobicity of the poly (methacrylic acid), the coacervate region increased, which indicates coacervation is favored in more complex systems with the hydrophobic regions.

▼ Adhesion of Salmonella Enteritidis in lettuces leaves of hidroponic and convencional systems was evaluated in reason of the native microbiota, with or without sanitization with chlorinated organic compound and vegetal roughness, using Atomic Force Microscopy. Besides, surfaces hydrophobicities of the lettuce leaves and S. Enteritidis were determined, through water contact angle and free energy. Also, a thermodynamic study was accomplished based on the quantification of the total free energy of interaction of the surfaces to foresee the pathogen adhesion on the leaf surfaces. The presence of Salmonella sp. Was not observed in none of the lettuces samples. Except filamentous fungi and yeasts counts, the lettuce cultivars grown hydroponically presented smaller counts (P <0,05) for aerobic mesophilic, lactic bacteria and coliforms at 35C. Sanitization with 200mg.L-1 of total residual chlorine, pH 6.8, during 15 min reduced (P <0,05) the counts of all of the microbial groups, altering the native microbiota of the lettuces surface. The adhesion of S. Enteritidis was larger (P <0,05) in the Hydroponic lettuce and in both types of lettuces after the sanitization procedure (P <0,05). Images obtained by Scanning Electron Microscopy showed that the leaf surface presented different micro photographic characteristics and that the present stomats in surfaces served as entrance and shelter for the pathogen cells. The roughness values showed that the surface of lettuces cultivars qrown hydropomically was more wrinkled (P <0,05), with average of 1211.2 nm. The lettuce of conventional cultivaiton presented a mediumroughness of 293.3 nm. The qualitative analysis of hydriohobicity revealed that the surface S. Enteritidis was hydrophilic and that the surfaces of the hydroponic and conventional lettuces can be classified as hydrophobic and slightly hydrophilic,respectively. Free energies values were positive (Δgsws >0) for the surface of conventional cultivaion lettuce, and for S. Enteritidis surface, indicating hydrophilic surface, while for the lattuce cultivas grown hydroponically the value of the free energy was nagative (Δgsws <0), in other words, hydrophonic. The main factors involved in the adhesion of the pathogen in this research were superfaces roughness and competitor microbiota. Adhesion of S. Enteritidis to the leave surface was thermodynamically unfarvirable, independent of the cultivation way (ΔgAdesão >0). Thus, the termodynamic evaluation explains the low number of S. Enteritidis cells adhered to the leave surface. Results show the importance of the vegetables sanitization processe and of the sppropriate production practices and suggest that the recontamination is an important factor to be considered. In that sense, the biological preservation should be considered as an additional measure a not like a substitution of the hygienic-sanitarium processes. Besides, the study of factors that involve the bacterial adhesion in foods surfaces is of great importance for the control of this process and the obtaining… Advisors/Committee Members: Sukarno Olavo Ferreira, Luis Antonio Minim, Cleuber Antonio de Sá Silva, Washington Azevedo da Silva, Nélio José de Andrade.

Baigiamojo darbo tikslas – ištirti vilnos pluošto paviršiaus hidrofobiškumo įtaką dažiklių sorbcijai vilnos pluošte ir dažinių fizikinėms savybėms. Naujų antrachinoninių dažiklių RB 5-37 Mėlynojo ir RB 4-35 Žaliojo sintezė buvo atlikta Kauno Technologijos universitete, Organinės chemijos katedroje, prof. V. Mickevičiaus grupėje. Siekiant nustatyti, kokį pluoštą ir kokiomis sąlygomis intensyviausiai dažo naujieji dažikliai, atlikti parengiamieji tyrimai su multipluoštiniu audiniu (ISO 105 F10 DW), kurį sudaro vilna, poliakrilatas, poliesteris, poliamidas, medvilnė ir diacetatas. Bandymo metu buvo nustatyta, jog tiriamieji antrachinoniniai dažikliai intensyviausiai dažo vilną ir poliamidą. Tolimesni tyrimai atlikti naudojant standartinį vilnonį audinį (ISO 150/F – 1985 (E)). Siekiant įvertinti hidrofobinio paviršinio barjero įtaką dažiklių difuzijai jame, bandymai atlikti su standartiniu vilnos audiniu ir su audiniu, nuo kurio paviršiaus buvo pašalintas hidrofobinis sluoksnis.

The aim of this work was to evaluate the effect of the hydrophobicity of wool fibre surface on the sorption of the dyes and on the physical properties of dyed wool fibre. New Anthraquinonic RB 5-37 Blue and Green RB 4-35 dyes synthesis was carried out by Professor V. Mickevičius group at Kaunas University of Technology, Department of Organic Chemistry. The multifiber fabric (ISO 105 F10 DW), composed of wool, polyacrylates, polyester, nylon, cotton and the diacetate was used in order to determine the fiber and the conditions under which the new dyes intensively dye. The dyeing results showed that new dyes wool fibers and polyamide dyed intensively. The standard wool fabric (ISO 150 / F - 1985 (E)) was used for further dyeing experiments. The standard wool fabric without pretreatment and wool fabric extracted with methanol and chloroform solvents mixture were used in order to evaluate hydrophobic wool surface barrier effect on dye diffusion in to wool fabric. It has also been done a kinetic study of dyeing process and dyed wool fiber single thread mechanical properties testing, i.e. breaking force and extension at break using a dynamometer. The investigation of the dyeing kinetic using two newly synthesized dyes showed that the Green dye which differs from the Blue by NO2 functional group, better penetrates into the wool fabric, irrespective of what was the composition of the dyeing solution.

Την τελευταία δεκαετία, η επεξεργασία υφασμάτων με πλάσμα έχει αποκτήσει μεγάλο τεχνολογικό ενδιαφέρον καθώς μπορεί να χρησιμοποιηθεί σε διάφορα στάδια της επεξεργασίας. Η οξείδωση της επιφάνειας, η ενίσχυση της υδροφιλίας ή της υδροφοβικότητας της και η αντιμικροβιακή δράση, είναι κάποια παραδείγματα τέτοιων εφαρμογών. Τα πλεονεκτήματα της τεχνικής του πλάσματος σε σύγκριση με άλλες τεχνικές είναι ότι είναι φιλική προς το περιβάλλον και ταυτόχρονα οικονομική αφού μειώνει τις απαιτήσεις σε νερό και ενέργεια. Παρόλα αυτά δεν υπάρχουν στη βιβλιογραφία επαρκείς μελέτες σχετικά με τους βασικούς μηχανισμούς που διέπουν τη διεργασία. Σε αυτή την κατεύθυνση επικεντρώσαμε στη μελέτη της επίδρασης του πλάσματος He/O2 σε χαμηλές πιέσεις με στόχο την ενίσχυση της υδροφιλίας της επιφάνειας, στη διερεύνηση της επίδρασης του C2F6 πλάσματος για την ενίσχυση της υδροφοβικότητας καθώς και στο σχηματισμό PEO-like υμενίων για την βελτίωση της αντιμικροβιακής δράσης της επιφάνειας. Πιο συγκεκριμένα, μελετήθηκε η επίδραση του ποσοστού οξυγόνου στο μείγμα του αερίου, του χρόνου επεξεργασίας, της συνολικής πίεσης και της ισχύος του πλάσματος στην μεταβολή των επιφανειακών ιδιοτήτων και κυρίως στην ενίσχυση της υδροφιλικότητας πολυεστερικών υφασμάτων πριν και μετά από το αποκολλάρισμα τους. Για τη μελέτη της υδροφοβικότητας πραγματοποιήθηκαν πειράματα ως προς την συνολική πίεση, το χρόνο διεργασίας και την απόσταση των ηλεκτροδίων. Τέλος, για την ενίσχυση της αντιμικροβιακής δράσης της επιφάνειας μελετήθηκε η συνολική πίεση, η ισχύς καθώς και το ποσοστό του οξυγόνου στο μίγμα. Οι αλλαγές που λαμβάνουν χώρα στην αέρια φάση και ο πιθανότερος μηχανισμός στον οποίο οφείλονται οι αλλαγές στην επιφάνεια του υποστρώματος μελετήθηκαν με την εφαρμογή διαγνωστικών τεχνικών του πλάσματος. Έτσι ηλεκτρικές μετρήσεις πραγματοποιήθηκαν για τον υπολογισμό της καταναλισκόμενης ισχύος και της εμπέδησης της εκκένωσης ενώ παράλληλα, πραγματοποιήθηκαν οπτικές μετρήσεις με στόχο την καταγραφή των ειδών που παράγονται στην εκκένωση και την κατανομή τους στον χώρο. Από την άλλη μεριά για τη μελέτη των δομικών και φυσικοχημικών μεταβολών που υφίσταται η επιφάνεια κατά την επεξεργασία της με πλάσμα χρησιμοποιήθηκαν ηλεκτρονιακή μικροσκοπία σάρωσης και φασματοσκοπία φωτοηλεκτρονίων από ακτίνες Χ. Τέλος, μετρήσεις του ρυθμού απορρόφησης σταγόνας, γωνίες αδιαβροχίας και προσρόφηση πρωτεϊνών χρησιμοποιήθηκαν ως μέτρο εκτίμησης της υδροφιλίας, της υδροφοβικότητας και της αντιμικροβιακής δράσης αντίστοιχα. Τα βέλτιστα αποτελέσματα παρουσιάζονται και συζητούνται σαν συνάρτηση των ιδιοτήτων του πλάσματος

▼ This study investigated the effect of detergent treatment on susceptibility of attached Escherichia coli and Listeria monocytogenes to subsequent disinfectant treatment, in relation to food industry cleaning procedures. E. coli attached to stainless steel surfaces became significantly more susceptible to benzalkonium chloride (BAC) after treatment with sodium alkyl sulphate (SAS) by 0.51 Log10 cfu ml-1 and fatty alcohol ethoxylate (FAE) by 0.96 Log10 cfu ml-1. No change in susceptibility was observed with sodium dodecyl sulphate (SDS), sodium lauryl ethyl sulphate (SLES) or polyethoxylated alcohol (PEA). L. monocytogenes became significantly less susceptible to BAC after treatment with anionic detergents SAS by 0.79 Log10 cfu ml-1, SDS by 0.33 Log10 cfu ml-1 and SLES by 0.22 Log10 cfu ml-1, yet no change in susceptibility was observed with FAE. Following treatment with all detergents both organisms became significantly more susceptible to sodium dichloroisocyanurate (NaDCC) demonstrating that the effect of the disinfectant was independent of detergent type. Flow cytometry using the fluorochrome propidium iodide (PI) revealed significant increases in cell membrane permeability of both organisms by all detergents except sodium dodecyl sulphate (SDS) and the effect was much greater in E. coli. Increasing above the in-use concentration of SAS and FAE had no further effect on cell membrane permeability, or susceptibility to BAC. Hydrophobic interaction chromatography (HIC) showed that E. coli became less hydrophobic following treatment with SAS, SDS, FAE and L. monocytogenes became less hydrophobic following treatment with SAS and SDS but no effect was seen with FAE. Investigations into carbon chain length of detergent revealed that SAS and the C18 standard increased susceptibility of E. coli to BAC which, with permeability results, suggests a link between increase in susceptibility to BAC and increase in membrane permeability. Efflux experiments with L. monocytogenes showed that efflux of ethidium bromide (EtBr) was greater from cells treated with SAS than with FAE suggesting that the anionic charge on the detergent molecule influences an efflux mechanism that reduces susceptibility to BAC. Overall the results demonstrate that detergent type can influence the sensitivity of persistent food borne microorganisms to BAC and NaDCC and the significance of the findings may impact on the choice of agents used in cleaning procedures in the food industry.

Mikrobiologija - bakteriologija / Microbiology - bacteriology

Infekcije izazvane bakterijama koje produkuju biofilm su jedan od najaktuelnijih problema u bakteriologiji. Biofilm je način odbrane bakterija od djelovanja antibiotika i imunskog sistema domaćina. Terapija infekcija izazvanih biofilmom je uglavnom neuspješna, jer su za eradikaciju biofilma potrebne visoke koncentracije antibiotika koje bi bile izuzetno toksične po domaćina. Zbog neodgovarajuće i neuspješne terapije, bilo bi veoma značajno otkriti faktore i uslove sredine koji dovode do nastanka biofilma ili ga čak i indukuju. Streptococcus pyogenes ili streptokok grupe A (GAS) je jedan od najučestalijih humanih patogena, koji izaziva širok spektar oboljenja, koje se na osnovu patogenetskih mehanizama nastanka mogu podijeliti na piogene infekcije, toksemične infekcije i poststreptokokne sekvele. Ovako širok spektar oboljenja GAS može da zahvali mnogobrojnim faktorima virulencije. Sposobnost formiranja biofilma kao dodatnog faktora virulencije je još uvijek nedovoljno ispitana za GAS, iako je biofilm kao značajan faktor virulencije potvrđen kod mnogobrojnih bakterija. Početni i najvažniji korak u formiranju biofilma je adherencija za supstrat, bilo da su u pitanju adherencija za ćelije domaćina ili za vještačke materijale. Streptococcus pyogenes raspolaže sa znatnim brojem adhezina koji mu omogućavaju adherenciju za različite humane ćelije. Najveći značaj adherencije je u pripajanju za ćelije domaćina, agregaciji blisko postavljenih bakterija, stvaranju signala za prelazak u kolektivni način života, pri kojem bakterije dobijaju zaštitni matriksni omotač, koji u planktonskom načinu života ne postoji, a koji je odgovoran za većinu odbrambenih mehanizama kojima bakterije u biofilmu izbjegavaju eradikaciju sa mjesta infekcije. Smatra se da produkcija biofilma omogućava in vitro osjetljivim sojevima rezistenciju na antibiotike i dovodi do terapijskog neuspjeha. Uočeno je da su bolji produktori neinvazivni sojevi različitih vrsta streptokoka u odnosu na invazivne sojeve, kao i da su GAS sojevi osjetljivi na eritromicin bolji produktori u odnosu na eritromicin rezistentne sojeve. Takođe, pretpostavlja se da streptokokno kliconoštvo najvjerovatnije nastaje prodorom bakterija u epitelne ćelije ili stvaranjem biofilma u kriptama tonzila...

▼ With an ever growing population, increased air pollution, and decrease of natural resources, the construction sector requires new sustainable solutions. Bio-materials, usually crop by-products, are considered a strong alternative to conventional building materials, and their use is not a direct competition in other supply chains like food crops can be. On top of their lower cost of manufacture (from both an economic and resource perspectives), they present attractive acoustic and thermal insulation properties. Specifically, the woody core of the hemp plant (Cannabis sativa L.), also named hemp shiv, acts as a moisture buffer due to its micropores, which allow water vapour to permeate. A wider adoption of this material as part of a building envelope is however hindered by the intrinsic chemical characteristics of hemp shiv. Made up mostly of cellulose and other sugar-derived polymeric groups, hemp shiv deteriorate in warm and humid environments, giving rise to microbial growth, and present a non-negligible fire risk. Their combustibility and predisposition to absorb liquid water are two issues which need to be addressed in order to enable their use in the built environment. This thesis presents the development of a silica particle technology to limit the biodegradation and improve the fire performance of hemp shiv. A rational design approach was followed for the synthesis of silica particles, by changing reactions parameters and the ratios of reagents. Better understanding of the effect of the reagents proportions and temperature on the synthesis allowed the size, porosity, and surface chemistry of the resultant silica particles to be tailored. Specifically, it was found that keeping the quantity of water between two boundary conditions enabled the controlled synthesis of discrete particles which diameters ranged from 120 to 820 nm with a defined pore shape distribution. Select formulations of particles of different sizes were then functionalised to make them hydrophobic, which was successfully assessed when functionalised silica particles were deposited on glass slides. Hemp shiv were then coated with selected formulations of functionalised silica particles, and their water repellence was equally verified, as well as the limitation of their water uptake, which increased from a few seconds to beyond 20 minutes. The samples also demonstrated delayed biodegradation when exposed to a humid environment, whilst retaining their moisture buffering and hydrophobic properties. Finally, silica was shown to act as a heat sink, by absorbing part of the radiant heat thus more energy was required for the onset of pyrolysis to occur. They also protected the hemp shiv against further oxidation, and consequently reduced their combustion rate. Composite structures made from hemp shiv in which the silica particles were introduced displayed improved fire performance, and similar response (although physical rather than chemical) when compared to composites treated with conventional fire retardant solutions. The approach followed here…

▼ This dissertation is a synopsis of advancements in the field of ionic liquids and a group of uniform materials based on organic salts (GUMBOS) in biomedical applications, especially with regard to cancer research. The toxicity of chemotherapeutic agents to normal tissues and drug resistance are a major concern in cancer treatment. In this dissertation, GUMBOS and nanoGUMBOS as well as ionic liquids and nanodroplets are explored as possible chemotherapeutic agents with minimal toxicity to normal cells. In the first part of my dissertation, exploitation of ionic liquid chemistry to modulate toxicity of rhodamine 6G is reported. Rhodamine 6G-based GUMBOS with varying counter-anions that are stable under physiological conditions, display excellent fluorescence photostability, and more importantly have tunable chemotherapeutic properties were synthesized. In vitro studies indicate that the hydrophobic compounds of this series allow production of nanoGUMBOS which are non-toxic to normal cells and toxic to cancer cells. Furthermore, the anions, in combination with cations such as sodium, were observed to be non-toxic to both normal and cancer cells. Thus, we demonstrate that both the cation and anion play an extremely important and cooperative role in the anticancer properties of these compounds. In the second part, the concept of multifunctional nanoparticles is introduced and exploited for theranostic applications. Nanoparticles possessing multiple properties such as luminescence, magnetism, and cancer targeting, were synthesized and explored for use in cancer therapy. In this regard, it is demonstrated that these nanoparticles can not only be used in diagnostics and as drug delivery agents, but also as active pharmacophores. Finally, the third part of this dissertation is a report of novel ionic liquid based pH sensitive colorimetric nanosensors based on phosphonium and fluorescein. The pH dependent size changes in the nanodroplets are demonstrated and potential applications in detecting acidic environment and anticancer activity are investigated.

▼ Sporeformers are common dairy contaminants, which are of a great concern to the dairy industry. Quality of dairy products is affected by these sporeformers such as Bacillus species, which are a significant cause of spoilage of dairy products. Thermal processes such as pasteurization have been used to inactivate pathogens, but some of the sporeformers and their endospores are resistant to such heat treatments. Beside thermal treatments, various new approaches are being developed to improve the quality of dairy products. Amongst these, ultrasonication is a promising non-thermal technique for the inactivation of thermoduric sporeformers and their endospores. Current study was carried out using ultrasonication as a non-thermal technique to evaluate its effect on biofilm forming ability, injured cells recovery, zeta potential and hydrophobicity of common dairy sporeformers. Three different bacteria, Geobacillus stearothermophilus (ATCC®15952), Bacillus licheniformis (ATCC® 6634), and Bacillus sporothermodurans (DSM 10599) were selected for this study based on our previous experiments. Skim milk was inoculated with a specific amount of spores or vegetative cells followed by ultrasonication for 10 min at 80% amplitude in an ice bath. The ultrasonicated cells were tested for the properties as outlined above. Based on the results, ultrasonication was observed to affect the ability of biofilm formation on stainless steel surfaces of all three sporeformers. Bacillus sporothermodurans formed the significantly higher biofilms, while Geobacillus stearothermophilus formed the least biofilms. In addition, a greater attachment was observed for B. sporothermodurans as supported by the highest hydrophobicity with least zeta potential among the three bacteria. On the other hand, G. stearothermophilus was found to attach less with least hydrophobicity and highest zeta potential. Overall, a positive relationship was found between attachment and hydrophobicity, when hydrophobicity increased, the capability of spores to attach stainless steel surfaces also increased. In addition, it was observed that injured cells were capable to regain and recover under favorable conditions, within as short as 4 hours. The results thus indicate that post-ultrasonication, the injured cells can recover, and replicate under favorable conditions to form biofilms. Advisors/Committee Members: Sanjeev Anand.

▼ Flame retardants (FRs) are compounds used in, e.g., electronics and furniture to prevent fires. Due to leakage, FRs are widely spread in the environment and several FRs have been found to be environmentally persistent, bioaccumulative and toxic. As a result, legacy FRs such as polybrominated diphenyl ethers (PBDEs) have been banned, and replaced by alternative FRs with often similar properties as the banned ones. The aims of this thesis were to develop an analytical method for the analysis of alternative FRs, to assess the current FR pollution in Sweden, and to improve the understanding of transport and fate of FRs within boreal catchments. In Paper I, gas chromatography (GC) coupled to tandem mass spectrometry (MS/MS) using an electron impact (EI) ion source was concluded to provide the best overall sensitivity, for most analysed FRs, including halogenated FRs (HFRs), organophosphorus FRs (OPFRs) and PBDEs. Alumina was found to be the superior material for clean-up of FR-containing extracts. In Paper II, Oasis HLB eluted with dichloromethane (DCM) was concluded to provide the highest overall recovery for the extraction of FRs from water. A high influence (both positive and negative) of natural organic matter (NOM) on extraction recovery was observed for all extracted FRs when extracted from NOM-containing water. The influence appeared to be systematic and the formation of a NOM-sorbent layer and the ability of certain FRs to form strong hydrogen bonds are suggested to be key mechanisms when extracting FRs from NOM-containing water. The concentrations of FRs in Swedish rivers were investigated in Paper III. ΣFR concentrations ranged up to 170 ng/L (mean 31 ± 45 ng/L) with generally higher concentrations in the south (latitude<62°N) than in the north (latitude>62°N). Several OPFRs are suggested to undergo long-range atmospheric transport (LRAT). Daily fluxes of FRs into the Baltic Sea were estimated to be 8.8 kg/day and comprised mainly tetrabromobisphenol-A (TBBPA), 3,4,5,6-tetrabromophthalic anhydride (TEBP-Anh), and 2,4,6-tribromo-phenol (TBP). This is presumably the first time environmental detection of TEBP-Anh is reported and it is suggested to originate from nearby airports. In Paper IV, elevated FR concentrations were observed in streams and rivers during spring flood and hydrophobicity fractionation was observed during snowmelt. HFR concentrations were generally higher at a mire site than at a forested site.

Adhesion of Bacillus cereus to stainless steel 3044 was evaluated after different times and temperatures of contact. Mathematical models were obtained capable of predicting the adhesion of B. cereus in stainless steel, as a function of temperature (4 °C 35 °C) and time (1d - 10 d). The interaction between the surface of stainless steel and B. cereus was studied by the characteristics of interfacial interaction, determined from the measurement of contact angle of the surface of B. cereus, stainless steel and stainless steel attachment with B. cereus, in association with the extended DLVO theory and the thermodynamic theory of adhesion. It was evaluated the microtopographies and the roughness of the surface of stainless steel and stainless steel attachment with B. cereus with the help of atomic force microscopy and perfilometry. The increase in temperature of 4 °C to 35 °C increased the number of B. cereus attached more than 3 cycles log for the time of adhesion of 1 d and more than 4 cycles log for the time of adhesion of 10 d showing the importance of temperature in adhesion. The maximum number of attached cells, found in coupons incubated for 35 °C for 10 days (log 4.43 CFU/cm2) was close to that of cells attached when the coupons remained at the same temperature for 1 day (log 4.01 CFU/cm2) showing once again the importance of temperature in relation to time to adhesion of this bacteria. When the temperature rose from 7 °C to 15 °C the number of CFU/cm2 increased about 3 cycles log. Only in the region of high temperature was a good adjustment of the data obtained by the mathematical model. The strain of B. cereus study was considered hydrophilic while the stainless steel was considered hydrophobic. The adhesion was not thermodynamically favorable (ΔGadesão>0) between the stainless steel and strain of B. cereus studied. Thus, the interaction between them was not favoured by thermodynamic aspect of adhesion. There was no difference (p>0.05) in the roughness of the surfaces of stainless steel attachment with B. cereus when analyzed by atomic force microscope and for perfilometry. The effect of temperature was more important than the effect of time on the adhesion of B. cereus to stainless steel 304 #4. The strain of B. cereus study was able to adhere to the coupons of stainless steel 304 #4 at low temperatures (4 C, 7 C and 10 C). The results indicated that possible abuses in the temperature of storage under refrigeration decisively affect the number of attached bacteria, which may adversely affect the quality of milk.
