1. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure
Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

2. Structural and Electronic Properties of Graphene on 4H- and 3C-SiC
Abstract : Graphene is a one-atom-tick carbon layer arranged in a honeycomb lattice. Graphene was first experimentally demonstrated by Andre Geim and Konstantin Novoselov in 2004 using mechanical exfoliation of highly oriented pyrolytic graphite (exfoliated graphene flakes), for which they received the Nobel Prize in Physics in 2010.

3. Microstructure and plastic deformation of textured CVD alumina coatings
Abstract : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. READ MORE

4. Assessment of human swallowing using in-vivo and in-vitro approaches
Abstract : Texture modification is the most vital strategy to manage dysphagia: a condition in which food and beverages are difficult to swallow. Typically thickeners in the form of starch or gums are added to the food to increase the viscosity and thereby reduce the speed of bolus flow. READ MORE

5. Nitride Thin Films for Thermoelectric Applications : Synthesis, Characterization and Theoretical Predictions
Abstract : Thermoelectrics is the reversible process which transforms a temperature gradient across a material into an external voltage through a phenomenon known as the Seebeck effect. This has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.
