1. Insights into Materials Properties from Ab Initio Theory : Diffusion, Adsorption, Catalysis & Structure
Abstract : In this thesis, density functional theory (DFT) calculations and DFT based ab initio molecular dynamics simulations have been employed in order to gain insights into materials properties like diffusion, adsorption, catalysis, and structure. In transition metals, absorbed hydrogen atoms self-trap due to localization of metal d-electrons. READ MORE

2. Theory of Hydrogen Quantum Diffusion
Abstract : Atomic hydrogen adsorbed on a metal surface is one of the simplest possible examples of chemisorption, yet it is very challenging. The adsorption and the very elementary process of surface diffusion, a single atomic jump, have been investigated theoretically using several methods. READ MORE

3. Ecostrategies in theory and practice : Farmer's perspectives on water, nutrients and sustainability in low-resource agriculture in the dry zone of Sri Lanka
Abstract : PROBLEMThe need for a sustainable man - nature relationship has long been a neglected aspect of development theory. The increasing awareness of this negligence has led to a search for development strategies alternative to conventional industrial growth. READ MORE

4. Energy Storage Materials: Insights From ab Initio Theory : Diffusion, Structure, Thermodynamics and Design
Abstract : The development of science and technology have provided a lifestyle completely dependent on energy consumption. Devices such as computers and mobile phones are good examples of how our daily life depends on electric energy. READ MORE

5. Quantitative methods for diffusion measurements in fluorescence microscopy
Abstract : In this work, statistical methods are developed for mapping mass transport locally based on images collected using a confocal laser scanning microscope. Besides presenting raster image correlation spectroscopy as an established method in fluorescence microscopy, we introduce a single particle tracking method which takes advantage of the raster scanning of the image in a confocal microscope.
