In this thesis, nanosuspensions of two hydrophobic active pharmaceutical ingredient compounds, mefenamic acid (MEF) and dalcetrapib (DCP) have been prepared using an antisolvent precipitation method (Chapter III and V, respectively). Variation of process parameters such as concentration, temperature, stirring rate or antisolvent to solvent ratio allowed for particle size reduction into the low micron (MEF, 0.25 µm – 3.05 µm) or nano (DCP, ~430 nm) size range. However, the suspensions of the prepared particles of both compounds were highly unstable and formed larger micron-sized agglomerates over time. A method of introducing different additives at different times during the process, i.e. stepwise addition of additives has been developed to improve the formation and stability of MEF nanocrystals (Chapter III). From the eight surfactant and polymeric additives evaluated to produce nanoparticles in suspension, the most effective additive was sodium docusate (DOSS). When DOSS was present initially in the system, nanoparticles, ~312 nm in size, were generated. However, the particle size was not stable but increased to ~788 nm after 80 minutes in suspension associated with a polymorphic transformation. Combining the initial use of DOSS with the subsequent addition of hydroxypropyl methylcellulose allowed for the production of a suspension of MEF nanocrystals (~317 nm) with improved stability. The size of the crystals did not change in the first two hours and only increased to ~365 nm after 18 hours. The interaction of hydroxypropyl methylcellulose with MEF particles delayed polymorphic transformation by inhibiting nucleation and/or growth of the stable MEF polymorph. The hypothesis that the reduction of the size of MEF nanocrystals in the presence of DOSS is due to nucleation promotion by the additive, a phenomenon rarely captured experimentally, was studied by performing a series of induction time experiments under moderate supersaturations, varying the solvent composition and the concentration of DOSS (Chapter IV). In 40 % dimethylacetamide – 60 % water and in the presence of DOSS (at concentrations of 0.1 mg/mL and 0.2 mg/mL), classical nucleation theory reveals that the pre-exponential factor (A) increases by approximately 50 % while the interfacial energy is essentially uninfluenced. It is also found that the crystal growth rate becomes higher in the presence of DOSS. It is thus hypothesized that transport and desolvation of MEF molecules is facilitated in the presence of DOSS. With increasing amount of dimethylacetamide in the binary solvent mixture, the influence of DOSS appears to decrease. As an alternative to using soluble additives, DCP nanoparticles have been stabilized and formulated as solid nanocomposites on larger montmorillonite (MMT) carrier particles. This method combines the very high dissolution rate of the DCP nanoparticles with the simple solid-liquid separation and drying of the MMT composite microparticles…

▼ Newly discovered zeolite, IM-17 (UOV), with a complex structure directed by decamethonium dications, is fascinating owing to its very large unit cell (12.68 Ã… Ã— 22.22 Ã… Ã— 39.06 Ã…). This poses some interesting questions in crystal growth as to how the crystal memory is propagated over such a large distance. To investigate how such a large unit cell forms and allows stacking layers is the aim of this research. The investigation demands a powerful tool to study nanoscopic details, which can be reached employing Atomic Force Microscopy (AFM). Here we report results of our work on four crystals having complex structures: IM-17, DAF-1 (DFO), zeolite Rho (RHO) and NU-87 (NES). The outcomes are also compared to the crystal models simulated using CrystalGrower program. The PXRD technique was used to confirm the as-prepared crystal structures. From the SEM micrographs, the crystal morphologies were revealed. The AFM exhibits the presence of terraces on all of the crystal surfaces. Cross-section and histogram height measurements of the terraces correspond to the growth steps of the materials. The IM-17 crystal showed two mechanisms of growth: layer-by-layer on both (100) and (013) facets and spiral growth on the (100) facet. Layer-by-layer terraces dissolved in patches in alkaline solution while the spiral layer retreated during the dissolution. Meanwhile, the terraces on DAF-1 crystal surfaces demonstrated patches dissolution in solution combination of decamethonium hydroxide and phosphoric acid. Interestingly, these layers maintained their terrace positions throughout the dissolution time. Such phenomenon is called 'surface thinning'. Zeolite Rho possesses the simplest structure among the Rho-family zeolites. It has twelve {110} facets, on which the terraces grow with the same shape and orientation as the facet. The height of the small terraces did not decrease during the terrace retreat in alkaline solution until the critical surface area to maintain the structure together were achieved, after which the terrace height started to decrease. The NU-87 crystal was very resilient to the alkaline and acidic solution attack. In addition, the very thin crystal morphology of the NU-87 disadvantaged the crystal etching in basic solution. All crystals under study and several dissolution processes were also simulated using CrystalGrower software based on the natural tiles. The simulated crystals were in a good agreement with the experimental results. The crystal models also proved very important to understand the crystal habit and their structure which cannot be solved in the laboratory.

▼ With there being a strong connection between the underlying structure of materials and their properties, understanding this inherent coupling will lead to more effcient materials. This thesis studies three non-centrosymmetric compounds MnSb2O6, Cu3Nb2O8 and CeRhSi3 with the goal of understanding the coupling between the structure and the underlying magnetic and electronic properties. All three materials lack an inversion centre and this thesis investigates how this constraint influences the underlying interactions and therefore properties of these compounds. MnSb2O6 is predicted to be multiferroic - a group of materials that has drawn considerable attention these days. One of the most interesting aspects of multiferroics is the so-called magnetoelectric coupling. Whereas in ferroics, one can tune magnetization with magnetic field, polarization with electric field, elasticity with stress, the idea behind multiferroics is that one can tune the electric polarization by the magnetic field (or vice versa). In terms of applications, the idea of electric-field control of magnetism is particularly exciting and it could lead to smaller and more effective devices. In the first part of this thesis, I discuss single crystal preparation based on three different methods in an attempt to obtain high quality single crystals for neutron inelastic scattering studies. Improvement in the size of single crystals was achieved using the flux method. This turned out to be an important step for inelastic experiment with the total mass of 1.3 g single crystals (approximately 150 sealed ampoules). Moreover, polycrystalline sample of MnSb2O6 has been prepared successfully with the hydrothermal method. To the best of our knowledge, this process of preparation has not been published before. The second part of the MnSb2O6 study is focused on neutron experiments and following analysis. The experiment on triple axis spectrometer RITA-II mapped behaviour of spins in horizontal magnetic field. Critical exponent β was estimated with discussion on properties of this system. Obtained results were compared with complementary experiment on BT4 spectrometer with same results. The magnetic and structural chirality was tested with polarized neutrons on instrument D3. Whereas, magnetic chirality in compound has a dominant domain, we were not able to confirm the same for the structural chirality. The last part of this section is discussing another interesting aspect of MnSb2O6 - it's noncollinear magnetic structure within triangular lattice is making it an ideal candidate to study so called multimagnon processes. The classical picture of magnon as non-interacting and long-lived excitation has been questioned by recent studies of classical systems with measured multimagnon excitations. Whereas existing spin wave theory can explain these excitations for quantum systems (S = 1/2), it doesn't provide an answer for their existence in classical systems. Cu3Nb2O8 compound belongs to type-II multiferroics, which means that electric polarization emerges at a magnetic…

▼ A survey of the methods of purification of KC1, for use in preparing single crystals by growth from the melt, was made. Two methods, fractional recrystallization and ion exchange, were used. The purity of the salt and crystals grown from the same salt were compared with the findings of other authors. The ion exchange method of purification produced a salt with < 0.01 ppm lead ion and the material was suitable as a "pure" host matrix for the study of the properties of lead ion in KC1 single crystals. Two crystal-growing apparatus were designed and built to produce pure and lead ion-containing KC1 single crystals in an atmosphere of air or other gases. A novel method of producing a "dual" crystal, one section pure, the other containing lead ion, in a continuous host crystal, was introduced. The incorporation of lead ion into these crystals was studied by means of spectrophotometry and evidence for the incorporation of the ion at more than one site was noted. The homogeneity of doping was considered a function of the crystal growth method and the manner of incorporation of the lead ion into the crystal. A scanning absorption cell was designed and built to observe the uniformity of lead ion distribution in the crystal. The dithizone method of trace analysis of lead was adapted to the analysis of KC1 single crystals containing lead. The oscillator strength of the 273 mμ band, called the A band, of lead ion in KC1 was found to be 0.11. A preliminary investigation of the thermal sensitivity of the A band and some other bands due to lead ion, observed in the 250-270 mμ region, was made. It was found that quenching from 600°C maximized the A band. The diffusion and electrolytic transport of lead ion were studied to evaluate the effective charge on the lead ion species migrating under the influence of an electric field. Migration was studied from both plane and extended sources and the mobility of the species at 560°C was found to be no greater than 8 x 10⁻⁹ cm²/volt sec. The effective charge on the species was determined to be no greater than 0.6 of an electronic charge. This value is smaller than the charge on the free lead ion, and it is suggested that the lead ion migrates as a complex. The possible complexes involve the association of positive ion vacancies or chloride ions with the lead ion. The reduction of lead ion to elemental lead near the junction between the pure and lead-containing regions partially explained the apparent migration of lead ion, in a field, toward the anode as observed by other authors. The conductivity of pure and lead ion-containing crystals was observed. The association energy of a positive ion vacancy with the lead ion was found to be about 0.1 eV or greater. An anomaly in the experimental conductivity curves is explained by the loss of lead ion from crystals. Advisors/Committee Members: Scott, Allen B (advisor).

▼ A simulation algorithm for crystal size distribution dynamics in a continuous crystallizer was developed using the method of lines. Dimensionless crystal sizes, in vector form, were used as state variables. Simulation results using this algorithm satisfied stability criteria for continuous crystallizers, which had been developed previously using different methods. The use of a state space representation of the algorithm permits the use of well-known theoretical and numerical approaches to the modeling of an experimental R-z crystallizer and for design of a proportional controller for a continuous crystallizer system. Boundary conditions defined by the nucleation/growth rate kinetics were separately written as an auxiliary function so that other kinetics can be substituted without any change of the main algorithm. This implies that the algorithm is applicable for any growth-type particulate system. CSD dynamics from an experimental crystallizer were satisfactorily modelled using this algorithm with reasonable parameters: e.g. the recycle ratios of the fines dissolver and the product classifier, crystal sizes at the upper cut size of the dissolver and at the lower cut size of the classifier, initial CSD, and the form of the upset. Algorithms for controller design using pole placement and optimization techniques were applied to develop a proportional matrix controller for an R-z crystallizer. It was evident that pole placement is a better method than optimization to design a controller for this crystallizer system. The system poles are concentrated at a point and it is necessary to assign the controller poles further apart to obtain appropriate control. To summarize controller design using the pole placement method, a schematic flow diagram of a system controller using the minimum order Luenberger observer was illustrated. In this example, only a few population densities need to be measured to drive the controller. Advisors/Committee Members: Randolph, Alan D (advisor), Peterson, Thomas W.

▼ Recently, the rare earth nitrides have received a considerable attention from theorists and experimentalists due to their potential applications in spintronic, piezoelectric, and thermoelectric devices. In this work, erbium nitride (ErN) and scandium nitride (ScN) crystals were grown and characterized experimentally, and the growth process was modeled and simulated. Erbium nitride (ErN) is a rare earth nitride notable for its magnetic and optical properties. Here we report on its growth on a non-native substrate, tungsten foil, via physical vapor transport, and its characterization. The source material was erbrium metal that was converted to ErN by heating in nitrogen. Subsequently, it was sublimed to form the ErN crystals. The operating conditions were 1620-1770 ⁰C and 150-330 Torr in pure nitrogen. The growth rate increased exponentially with temperature with an activation energy of 508 kJ/mol, and inversely with pressure. X-ray diffraction revealed the ErN preferentially adopted a (100) orientation, the same as the dominant orientation of the tungsten sheet. The lattice constant was 4.853 Å. The crystal shapes and sizes were dependent on the temperature, as revealed by SEM and optical microscopy. The ErN crystals were highly faceted, bound by (100) and (111) crystal planes. The ErN compound deviated from stoichiometry: the Er:N atomic ratio ranged from 1:1.15 to 1:1.2 according to EDX and XPS elemental analysis. Raman spectra was in good agreement with theoretical predictions. Scandium nitride single crystals (14–90 µm thick) were grown on tungsten (100) single crystal substrate by physical vapor transport in the temperature range of 1850-2000 ⁰C and pressure of 15-35 Torr. Epitaxial growth was confirmed using in-plane ɸ scan and out-of-plane x-ray diffraction techniques which revealed that ScN exhibited cube-on-cube growth with a plane relationship ScN (001) || W (001) and normal direction ScN [100] || W [110]. Atomic force microscopy revealed the surface roughness decreased from 83 nm to 18 nm as the growth temperature was increased. X-ray diffraction (XRD) rocking curves widths decreased indicating the crystal quality improved with increasing growth temperature. The lowest XRC FWHM was 821 arcsec, which is so far the lowest value reported for ScN. Scanning electron microscopy (SEM) exhibited the formation of macrosteps and cracks on the crystal surface with latter due to the mismatch of ScN’s and tungsten’s coefficients of thermal expansion . In general for crystal growth, material should deposit on the seed crystal and not on any adjacent supporting structures. This efficiently uses the source material and avoids the possibility of spurious polycrystals encroaching on, and interfering with the single crystal growth. To achieve this goal, a new crucible design with a cooling fin in contact with the seed was simulated and experimentally demonstrated on the physical vapor transport (PVT) crystal growth of scandium nitride. The heat transfer of the growth cavity for a conventional crucible and a modified… Advisors/Committee Members: James H. Edgar.

peer-reviewed

The crystal growth process and associated kinetics of two active pharmaceutical ingredients (API) has been investigated using three crystal growth methods. The impact of organic solvent, supersaturation, temperature, polymorph form, and crystal seed quality on the crystal growth was studied. Isothermal seeded desuperaturation (ISD) growth method was used to investigate the growth rate of multiple salicylamide (SAM) crystals simultaneously. In-situ fourier transform infrared (FTIR) spectroscopy probe was employed for the determination of solution concentration and supersaturation decay data obtained was modelled using several growth rate equations and growth models, also tested different representations of the driving force. ISD provides kinetic data which was statistically representative of the crystal population due to the large number of crystals studied. Measuring the interfacial angle between faces combined with preferred orientation X-ray diffraction (XRD) was found to be the most accurate and reliable method leading to successful identification of each predicted SAM crystal face. Cuvette (CV) growth method was used to study the growth of single SAM crystals and the crystal growth rates were measured for both primary nucleated crystals and seed crystals manually inserted into the cuvette. As each facet had been face indexed it allowed for the growth of specific crystal facets, i.e. (200) of SAM, to be extracted directly from single crystals using a microscope. In an attempt to study multiple single crystals at once under controlled hydrodynamics, crystal seeds were grown using a new approach called the rotating disk (RD) growth method. Wherein seed crystals were attached to a disk that was rotated in a supersaturated solution by which the diffusion resistance was found to be eliminated. RD method was used to study the growth of two APIs including SAM and FII & FIII polymorphs of piracetam (PCM). It was deduced that ethyl acetate was adsorbed more strongly on the faces of SAM than the other solvents tested, the increased size of which, explained the irregular hexagonal plate habit obtained and relatively slow growth rates. Growth rate of the (011) facet of piracetam FII and FIII crystals was found to be reduced in isopropanol also due to its stronger interaction. Metastable PCM FII was found to have faster growth rates than the thermodynamically stable FIII. Within the range of experimental conditions, the growth rates of SAM and PCM were strongly affected by the temperature and also supersaturation. With a 10 °C increase resulting in a two to fourfold increase in the average growth rate depending on the solute – solvent system. Similarly, a two to fourfold increase in the average growth rate of both SAM and PCM was observed when the supersaturation was increased within the range of S-1 0.02 up to 0.10. Also SAM’s crystal seed quality was found to have a substantial impact on the growth rate, with rougher larger crystals leading to…

▼ Photonic crystals are optical materials with periodically distributed refractive indices. Their photonic bandgap effect on the flow of photons makes them appear colored like the wings of a Morpho butterfly. They have potential for use in nano lasers, photovoltaics, nonlinear optics, and other applications. Most of artificial photonic crystals are made by photolithography. For three-dimensional photonic crystals having their photonic bandgaps in the visible spectrum, the required precision and accuracy of fabrication are extremely high. Blue phases (BP) are a class of particular liquid crystal (LC) phases located between the isotropic and cholesteric phase. Such materials in their blue phases (BPI and BPII) organize spontaneously into three-dimensional cubic nanostructures. By controlling the chirality of the material or applying external fields, the color (bandgap) of a BPLC can be modulated. The conventional way of growing BP crystals is to cool the sample slowly and homogeneously from the isotropic state to the blue phase, resulting in polycrystalline texture. The diameter of each single crystal can range from 3 to 200 Î¼m depending on the cooling rate. BP polycrystals often lack uniform lattice directions, sufficient number of periods, and grain boundaries cause optical scattering, therefore hindering their applications. In this study, we created spatial temperature gradient by using two temperature-controlled stages. One stage was set at a temperature above the clearing point (the ISO stage) and the other at a temperature in the BP range (the BP stage). The BP crystal growth was conducted by moving the sample from the ISO stage to the BP stage. The single BP crystals thus grew along the moving direction. The resulting single crystals are considerably larger than those grown by the conventional approach. In this thesis, we discussed the parameters that affect the grain size, such as material, temperatures of stages, moving rate, and the addition of external fields. In the experiments, we examined the grain size and other properties of the BP crystals by means of microscopic images, KÃ¶ssel diagrams, spectra and voltage-transmittance diagrams. By adopting the proposed strategy for crystal growth, we have achieved millimeter-sized BP single crystals, enabling a wider range of applications and more in-depth fundamental research.

▼ The crystal growth of nanoporous materials is different from most other classes of material in that their framework architectures contain periodic arrangement of pores or voids in which there is no direct bonding between adjacent units of the framework. This poses a variety of questions as to how such parts of framework develop during the crystallization process, atomistically and energetically. Here we use the nanoporous metal-organic framework, ZIF-8 as a prototypical material to obtain a basic understanding of the growth of a nanoporous material. The crystals of ZIF-8 produced in the N,N-dimethylformamide solvent [ZIF-8(DMF)] and methanol-co-N,N-dimethylformamide solvent [ZIF-8(MeOH)] are both rhombic dodecahedron in shape with a much smaller crystal size in the latter. In the study of the kinetics of ZIF-8(DMF) crystallization, we get a good agreement in the values of activation energies using both Avrami-Erofe’ev-Hancock-Sharp and Gualtieri’s models, i.e. about 120 kJ mol-1 for nucleation, and 95 kJ mol-1 for crystal growth process. The study of kinetics of ZIF-8 surface growth, by in situ AFM, with ZIF-8(DMF) as seed crystal that are grown in the methanolic growth solution we see faster rate in the <100> directions than the <110> directions, with the most probable activation energy of about 80 kJ mol-1 in both directions. This is the first example of in situ AFM being used to obtain activation energy for a surface growth in MOF. We also reveal here that growth process of ZIF-8 occurs through the nucleation and spreading of successive metastable unenclosed sub-steps to eventually form stable terrace steps of the enclosed framework structure in which this process is reliant on the presence of nonframework species to connect the framework species that have voids between them. The experiments also enable identification of some of the fundamental units in the growth process and the stable crystal surface plane. Further, the spreading of terraces at high supersaturation condition (early state) is fairly isotropic as is seen through the formation of almost-rounded terraces on the surface of ZIF-8. The growth direction becomes clear as the supersaturation condition nears to equilibrium (later stage) by the formation of rhombohedral terraces with pointy ends growing along the <100>, and <110> directions and straight edges growing perpendicular to the <111> direction. Formation of this rhombohedral morphology is explained by a coarse grain approach similar to that used in the Kossel model by making assumptions that the sodalite cage is the growth unit and attachment of one sodalite cage in each growth direction is the rate determining step for the formation of a new row of sodalite cages in each direction. Finally, based on the profiles of growth spirals formed from screw dislocations on the ZIF-8 surface obtained from the ex situ AFM images and ICE theory, plausible screw dislocations with Burgers’ vector of 1/2 <111> and <100>, but not <110>, are deduced. Some of the findings in this work will be applicable to numerous…

▼ Newly discovered zeolite, IM-17 (UOV), with a complex structure directed by decamethonium dications, is fascinating owing to its very large unit cell (12.68 Å x 22.22 Å x 39.06 Å). This poses some interesting questions in crystal growth as to how the crystal memory is propagated over such a large distance. To investigate how such a large unit cell forms and allows stacking layers is the aim of this research. The investigation demands a powerful tool to study nanoscopic details, which can be reached employing Atomic Force Microscopy (AFM). Here we report results of our work on four crystals having complex structures: IM-17, DAF-1 (DFO), zeolite Rho (RHO) and NU-87 (NES). The outcomes are also compared to the crystal models simulated using CrystalGrower program. The PXRD technique was used to confirm the as-prepared crystal structures. From the SEM micrographs, the crystal morphologies were revealed. The AFM exhibits the presence of terraces on all of the crystal surfaces. Cross-section and histogram height measurements of the terraces correspond to the growth steps of the materials. The IM-17 crystal showed two mechanisms of growth: layer-by-layer on both (100) and (013) facets and spiral growth on the (100) facet. Layer-by-layer terraces dissolved in patches in alkaline solution while the spiral layer retreated during the dissolution. Meanwhile, the terraces on DAF-1 crystal surfaces demonstrated patches dissolution in solution combination of decamethonium hydroxide and phosphoric acid. Interestingly, these layers maintained their terrace positions throughout the dissolution time. Such phenomenon is called 'surface thinning'. Zeolite Rho possesses the simplest structure among the Rho-family zeolites. It has twelve {110} facets, on which the terraces grow with the same shape and orientation as the facet. The height of the small terraces did not decrease during the terrace retreat in alkaline solution until the critical surface area to maintain the structure together were achieved, after which the terrace height started to decrease. The NU-87 crystal was very resilient to the alkaline and acidic solution attack. In addition, the very thin crystal morphology of the NU-87 disadvantaged the crystal etching in basic solution. All crystals under study and several dissolution processes were also simulated using CrystalGrower software based on the natural tiles. The simulated crystals were in a good agreement with the experimental results. The crystal models also proved very important to understand the crystal habit and their structure which cannot be solved in the laboratory.

▼

Crystallising large, flexible molecules, which are becoming more common in pharmaceutical development, often presents significant challenges for chemists and particle scientists. These difficulties are sometimes attributed to the flexibility of the molecule, and the existence of multiple conformers in solution. Structurally related impurities, frequently present when crystallising these materials, can also impact on growth and habit, and both these aspects are considered in this thesis. This work considers two pharmaceutical compounds, a relatively small but nonetheless flexible molecule, ethenzamide, and a precursor of Amprenavir, a much larger molecule. Both compounds typically grow as thin needles in a wide variety of solvents, and effort was required to grow suitable crystals for structure determination. Ethenzamide has an unusual structure, the amide group being out-of-plane relative to the ring, while in all known co-crystals of the compound, including three new co-crystal structures determined in this work, it has a planar structure with an intramolecular hydrogen bond not seen in the single component crystal. Theoretical structure generation calculations suggest a second polymorph with a planar conformation may exist, though a screen has not found any further solid phases. ab initio work suggests the planar conformation is the stable arrangement in vacuo. Several structures for the Amprenavir intermediate have been determined, as an ethanol solvate, a methanol solvate and a hydrate. A phase diagram has been measured in the industrial solvent mix, and the nucleation and growth properties of this molecule, both pure and in the presence of several structurally related impurities, have been measured. The Cambridge Structural Database has been searched for similar structures, and conformational searches have been carried out for both molecules, using vacuum phase ab initio energy calculations. Infrared spectroscopy has been used to investigate solution phase structure. These theoretical and practical studies will try to relate conformational properties to crystallisation behaviour.

▼ Synthesis and single crystal growth methods for Li-containing chalogenides, specifically LiIn1-xGaxSe2, single crystals are discussed. This study elucidates the possibility of improving neutron detection by reducing the indium capture contribution; with the incorporation of the lithium-6 isotope, gallium substitution may overcome the neutron detection efficiency limitation of 6LiInSe2 due to predominant capture by the indium-115 isotope. As a figure of merit, the ternary parent compounds LiInSe2 and LiGaSe2 were included in this study. Quality crystals can be obtained utilizing the vertical Bridgman method producing quaternary compounds with tunable optical properties. Quaternary crystals of varying quality depending on gallium concentration, approximately 5 x 5 x 2 mm3 or larger in volume, were harvested, analyzed and revealed tunable absorption characteristics between 2.8-3.4 eV. The electronic structure and optical properties of the LiIn1–xGaxSe2 (x=0, 0.25, 0.5, 0.75, 1) solid solution were studied by density functional theory (DFT) with pure functionals. The exchange-correlation is treated within the local density approximation (LDA) and generalized-gradient approximation (GGA). The electronic structures for each respective compound are discussed in detail. Calculations reveal that gallium incorporation can be used to tune the optical-electrical properties of the solid solution and correlates with the lattice parameter. The band gap trend of the LiIn1–xGaxSe2 system follows a nonlinear behavior between the LiInSe2 and LiGaSe2 ternary boundaries. The bowing parameter is estimated to be on the order of 0.1–0.3eV at the -point. Low-temperature optical absorption revealed a 30% change in the temperature dependence of the band gap for the intermediate compound LiIn0.6Ga0.4Se2 compared to ternary boundaries and suggests the heat capacity to be another control element through strain.

The discovery of first high-Tc cuprate superconductor in 1986 has boosted the research in strongly correlated materials. The motivation for understanding the mechanism of superconductivity has increased much in order to engineer novel superconducting materials with high transition temperatures. Hence, the investigation of other families (non-cuprates) of superconductors has been of great interest that might also help to understand the mechanism of superconductivity. The program of my doctoral thesis was two-fold: (i) studies on the synthesis and crystal growth of layered sodium cobalt oxide (NaxCoO2) and investigations on their thermal, structural and physical properties; (ii) synthesis of newly discovered K doped MFe2As2 (M = Ba and Sr) and Ru doped BaFe2As2 superconductors by novel methods and to study their structural and superconducting properties. Both the systems are of layered structure like high Tc cuprates and d electrons play a crucial role on the conduction band. The main difference is that the NaxCoO2 system has the triangular lattice symmetry and Fe-pnictide compounds have the tetragonal coordination when compared to the square planar coordination in cuprates. The first chapter provides a brief introduction about superconductivity. The second chapter presents the review on NaxCoO2 and Fe-pnictide superconductors. Also various experimental techniques used for the sample characterisation are given in this chapter. The third chapter comprises of the synthesis, deintercalation/interaction studies and characterization of the polycrystalline NaxCoO2. Synthesis of NaxCoO2 compounds with precise x value is difficult due to volatile nature of Na. In the present work, NaxCoO2 (x = 0.75, 0.80 and 0.90) samples were synthesized by modified quenching method. Samples with lower x values (x = 0.30 and 0.40) were prepared by bromination method. The melting behavior of NaxCoO2 was analyzed by TG-DTA measurements. All the samples were identified as single phase by means of powder newlineXRD studies.
