First-principles studies of perovskite thin films and heterostructures
… however, the effects of film growth, atomic adsorption, and strain can have fundamental effects on the properties of the oxides in question. In this dissertation, we use density functional theory to calculate the properties of SrTiO₃ and BaTiO₃, and discover the effects of the environment on …

Surface Structure/Property Relationship for (001) Surface of Magnetite
Magnetite (Fe3O4), a well-known magnetic material, is still attracting intense study because of its great application in catalyst and technology development. These useful properties are related to the coexistence and coupling of several degrees of freedom, including charge, lattice, orbital and …

Catalytic upgrading of biomass through the hydrodeoxygenation (HDO) of bio-oil derived model compounds
… (010) surface to reveal dissociative H₂ adsorption on the (010) surface to be the rate-limiting step. Kinetic studies on MoO₃ supported on ZrO₂ reveal the differences in reaction mechanism and the nature of active sites for HDO on MoO₃/ZrO₂ as compared to bulk MoO₃. The third section …

Evaluating Steel Byproducts and Natural Minerals for Phosphate Adsorption from Agricultural Subsurface Drainage
… to the loss of P from soils. The use of adsorption materials to bind P has emerged as a promising technology for P removal. The objective of this study was to perform batch and column experiments to investigate the P adsorption potential of several materials for agricultural subsurface …

A theoretical investigation in heterogeneous gold catalysis
… On an AU13 cluster, the energetics of CO2 adsorption and hydrogenation remain unfavourable. The cluster-size dependency of hydrogen and carbon monoxide adsorption was investigated. It was found that small gold clusters (1 to 13 atoms in size) can bind both H and CO strongly. Due to the …

Novel amorphous silica and silica xerogels for the adsorption of organic pollutants from water
… for water remediation and the use of an adsorption media as a prior treatment could make them a potentially cost-effective option. Among solid sorbents, hydrophobic aerogels exhibit attractive properties for oil spill applications; however, very few studies have investigated their …
