Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...
This study investigated learning in three engineering student clubs at a large public university. This included a small-sized chemical reaction car competition, a large-sized formula racing team, and an international humanitarian engineering club. Research methods included observations of work sessions (N=27) and semi-structured interviews (N=19). Using Cultural Historical Activity Theory...
Rising CO₂ concentrations in the atmosphere (396 ppmv as of April 2012)
increase the effect of global warming and climate change. CO₂ sequestration has become
a potential method to mitigate climate change. This study focuses on capillary/residual
trapping as a form of geologic CO₂ sequestration. Capillary/residual trapping occurs
when supercritical...
