Abstract:

Cocrystals have generated a lot of interest due their ability to influence: physiochemical properties, optical properties etc. These properties are important in the pharmaceutical and food industry. In this thesis, the scale up of cocrystal synthesis is studied using a novel slurry cocrystallisation approach involving an anti-solvent and solvent mixture. The anti-solvent composition is typically > 97 %, with the solvent comprising the rest. This counter-intuitive approach resulted in > 95 % caffeine-oxalic acid cocrystal yield in less than 2 hrs. The mixed anti-solvent/solvent approach was app

Abstract:

This paper considers a free energy functional and corresponding free boundary problem for multilayered structures which arise from a mixture of a block copolymer and a weak solvent. The free boundary problem is formally derived from the limit of large solvent/polymer segregation and intermediate segregation between monomer species. A change of variables based on Legendre transforms of the effective bulk energy is used to explicitly construct a family of equilibrium solutions. The second variation of the effective free energy of these solutions is shown to be positive. This result is used to sh

The focus of this project is to find a suitable method to determine the mixing ratio inbinary fluid mixtures in continuous-flow microfluidic systems because of thedifficulties in doing so for mixtures containing compressible fluids. Refractive indexand relative static permittivity are both properties that could be suitable, but methodsmeasuring the refractive index scales badly for microsystems. A microfluidic chip for measuring capacitance was placed on a PCB together with amixing structure with strain-relieved fluid and electrical interfaces.

Salt forms homogeneous solutions with water; most studies to date have assumed that deep eutectic solvents (DES) and water form similar homogeneous systems.

Materials based on amphiphilic molecules have a wide range of industrial applications and are of fundamental importance in the structure of many biological systems. Their importance derives from their behaviour as surface-active agents in solubilization applications and because of their ability to form systems with varying degrees of structural order such as micelles, bilayers and liquid crystal phases. The nature of the molecular ordering is of importance both during the processing of these materials and in their final application. A Monte Carlo simulation of a three dimensional lattice model

Abstract:

Aprotic solvents are organic solvents which do not easily react with a substance dissolved in it and they do not exchange protons despite of their high ion and polar group dissolving power. Therefore, this characteristic property makes aprotic solvents very suitable intermediates in many industries producing pharmaceuticals, textile auxiliaries, plasticizers, stabilizers, adhesives and ink. Dehydration of these mixtures and recirculation of valuable materials are substantial issues in industrial applications. The conventional method for recovery of aprotic solvents has been distillation, which

Abstract:

N-methyl-2-pyrrolidone(NMP) and ionic liquids(ILs)are solvents with “green” characteristics, such as low volatility and low toxicity. They can be used as a valid alternative to the common organic solvents with a high environmental, health and safety impact. The aim of my research was to investigate their thermodynamical, structural, and dynamical properties, both in the neat state and in mixture, by using a combined approach of different experimental techniques together with computational ones. In PAPER I, the structural effect of water on NMP over the whole concentration range were stu

Abstract:

L'amélioration de la solubilité est un aspect critique dans la formulation et le développement de nouvelles molécules thérapeutiques. Pour surmonter les défis associés à une faible solubilité, les chercheurs ont évalué de nombreuses stratégies, dont l'utilisation de cyclodextrines et de cosolvants. Cette dernière approche est une technique simple et efficace, dans laquelle des solvants organiques sont utilisés pour améliorer la solubilité des composés peu solubles dans l'eau. Ces dernières années, les solvants eutectiques profonds (DESs) ont émergé comme une alternative abordable et verte comp
