Density functional theory calculations have been used to study the adsorption of methylamine and methanol on the hydroxylated (0 0 0 1) surface of α-quartz. The surface structure for these calculations was based on the structure reported recently by

The structure, formation and decomposition pathways of 2-butoxide species formed on a Pd(1 1 1) surface following the adsorption of 2-butanol is studied by a combination of density functional theory (DFT), analysis of the low-energy electron intensit

The physico-chemical properties of cinchona alkaloids have been characterized in connection to their use for catalytic enantioselective conversions. Adding to the previous identification of their active site at the nitrogen atom in the quinuclidine r

Chiral modification of achiral metal catalysts with chiral auxiliary molecules is a promising method of creating chiral surfaces for heterogeneous catalysis. The ability of a chiral template overlayer to affect the adsorption enantioselectivity of a

Many phenomena can occur when chiral molecules adsorb on solids. Density Functional Theory calculations have provided information that strongly complements experimental studies. Advances have been made in two related avenues for creating surface chir

Acetate adsorbs on Pd(1 1 1) as a disordered overlayer. We have used a recently developed LEED I–V technique that allows the structure of disordered molecular overlayers to be examined to determine the structure of acetate adsorbed on Pd(1 1 1). Ou

The structure of formate species adsorbed on Pd(1 1 1) has been determined using low-energy electron diffraction (LEED). The presence of formate species on the Pd(1 1 1) surface was established using reflection-absorption infrared spectroscopy (RAIRS

Experimental studies have reported that glycine is adsorbed on the Cu(110) and Cu(100) surfaces in its deprotonated form at room temperature, but in its zwitterionic form on Pd(111) and Pt(111). In contrast, recent density functional theory (DFT) cal
