Reactions of NO2, H2O, and CO2 with a thick (>20 monolayer equivalent (MLE)) BaO film supported on Pt(111) were studied with temperature programmed desorption (TPD) and X-ray photoelectron spectroscopy (XPS). NO2 reacts with a thick BaO layer to form surface...

We have modelled the surface diffusion and growth of BaO and SrO both in the homoepitaxial and heteroepitaxial (BaO on SrO and SrO on BaO) cases. The diffusion proceeds most favourably by an exchange mechanism involving the surface layer. When...

It is unclear if fiber-reinforced fixed dental prostheses can be fabricated with physical properties that make them suitable for definitive prostheses. The purpose of this study was to compare the load bearing capacity of fiber-reinforced and unreinforced computer-aided design/computer-aided manufacturing...

Thermochemiluminescence (TCL) of organic compounds or biological substances is an interesting phenomenon and has been applied to polymer analysis and medical diagnostics. We improve traditional TCL assays using the assistance of catalytic nanomaterials and construct a nanomaterials array for the...
