Energy Transfer Dynamics in Collisions of Polar and Non-polar Gases with Functionalized Self-Assembled Monolayers
Molecular beam scattering experiments are used to investigate the extent of thermal accommodation of Ne, CD4, ND3, and D2O in collisions with long chain CH3, NH2, and OH terminated self-assembled monolayers (SAMs) on gold. Surface rigidity, internal degrees of freedom of the impinging gas, and …

Interfacial Energy Transfer in Small Hydrocarbon Collisions with Organic Surfaces and the Decomposition of Chemical Warfare Agent Simulants within Metal-Organic Frameworks
A molecular-level understanding of gas-surface energy exchange and reaction mechanisms will aid in the prediction of the environmental fate of pollutants and enable advances toward catalysts for the decomposition of toxic compounds. To this end, molecular beam scattering experiments performed in an …

Effects of phosphorus on bond rupture during hydrodeoxygenation and dehydrogenation reactions on ruthenium
… programmed reaction (TPR) and reactive molecular beam scattering (RMBS) experiments were used to determine bond rupture barriers and selectivity of C-O bond rupture compared to C-H/C-C bond rupture. The TPR results showed that longer alkyl carbon chains can promote self-stabilizing …
