2. Surface Stabilization and Electrochemical Properties from a Theoretical Perspective
Abstract : Diamond and cubic boron nitride surfaces have extreme properties that can be exploited in novel tribological, electrochemical and electronic applications. Normally insulating diamond surfaces can exhibit high surface conductivities due to hydrogen termination and the nature of the surrounding atmosphere. READ MORE

3. Reactivity of Transition-Metal Compounds from Electronic Structure
Abstract : Transition-metal carbides (TMC's), nitrides, and sulfides belong to the class of materials known as transition-metal compounds (TMX's). Besides having intriguing properties, these materials are relevant for, e.g., growth and catalysis. READ MORE

5. A surface approach to understanding the dissolution of fluorite type materials : Implications for mineral dissolution kinetic models
Abstract : Traditional dissolution models are based in the analyses of bulk solution compositions and ignore the fact that different sites of a surface dissolve at different rates. Consequently, the variation of surface area and surface reactivity during dissolution are not considered for the calculation of the overall dissolution rate, which is expected to remain constant with time.
