First-Principles Theory of Surface Thermodynamics and Kinetics

Understanding the complex behavior of particles at surfaces requires detailed knowledge of both macroscopic and microscopic processes that take place; also certain phenomena depend critically on temperature and gas pressure. To link these processes we combine state-of-the-art microscopic, and macroscopic phenomenological, theories. We apply our theory to the O Ru(0001) system and calculate ther...

Molecular-scale formation of carbonate solid solutions from multicomponent aqueous solutions and other related phenomena

This work deals with the growth behaviour of calcite surfaces in contact with multicomponent carbonate aqueous solutions containing divalent cations (Ba, Sr, Mn, Cd or Mg). The result of solid surface-aqueous solution interactions is the formation of solid solutions, with calcite as one of the end-members. In situ Atomic Force Microscopy and other surface techniques have revealed a wide variety...

Role of Surface Phenomena on Converter Slag Composition

For beneficiation of converter slag, the role of surface phenomena on slag composition was studied. This work includes some experimental data, which were measured for basic oxygen steel (BOS) slag in Isfahan Steel Plant. All data were collected on site in the plant. The results support the idea that surface activity plays a major role in converter slag formation. It was also a new finding t...

Non-Dissociative Gas Adsorption with Different Chemisorption Geometries on Nanoporous Surfaces

Isotherm equation is one of the important scientific bases for adsorbent selection. There are different isotherms that do not account for an adsorbate, different chemisorption geometries on the nanoporous surface. It is interesting to introduce a general isotherm, which considers different chemisorption geometries of an adsorbate on nanoporous surfaces. In this study, an isotherm for non-dissoci...
