21. Properties and applications of materials based on graphite oxide
Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE

23. Functional Copolymers of Polyvinylpyrrolidone
Abstract : In many ways, polyvinylpyrrolidone (PVP) has a unique combination of chemical and physical properties. Unlike most polymers it is soluble in water as well as a number of organic solvents. PVP also has excellent film forming properties, outstanding chemical stability, complexing ability, low toxicity, and good adherence to many different substrates. READ MORE

25. Development of Novel In Situ ESEM Techniques for the Study of Water Interaction with Soft Materials
Abstract : The transport of water is central to many applications of soft biomaterials; for example water management in personal care products, controlled drug release in pharmaceuticals and, on a fundamental level, the activities of living cells. Water transport through a material may occur in both liquid and gas phase, and is highly dependent on the microstructure. READ MORE
