1. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation
Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.

2. Understanding Adhesive Mixtures for Inhalation : Particle Dynamics Modelling and Segregation Experiments
Abstract : Pulmonary route has been used as a source of drug delivery to lungs for centuries. Drugformulation decides the type of inhaler devices such as pressurized metered-dose inhalers(pMDIs), nebulizers and dry powder inhalers (DPIs). READ MORE

3. Transition in Particle-laden Flows
Abstract : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. READ MORE

4. Preparation of Pharmaceutical Powders using Supercritical Fluid Technology : Pharmaceutical Applications and Physicochemical Characterisation of Powders
Abstract : The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. READ MORE

5. Molecular Mechanisms Influencing the Performance of Amorphous Formulations for Poorly Water-Soluble Drugs
Abstract : Crystallisation is a concern for amorphous formulation because it compromises the solubility-enhancing benefit gained from amorphisation. Traditionally, amorphous formulation had been designed primarily based on trial-and-error approach. READ MORE
