Low-energy collisions of ionized acetone-d, , DMSO-d, and pyridine-d, with alkanethiolate self-assembled monolayer (SAM) surfaces prepared on gold were investigated. These experiments can be used to monitor routinely the condition of the surfaces and to determine whether a surface is acceptable for a given application. In addition to the surface-induced dissociation of the molecular ions, inten...

Equilibrium structures and thermodynamic properties of dodecanethiol self-assembled monolayers on small (Au140) and larger (Au1289) gold nanocrystallites were investigated with the use of molecular dynamics simulations. Compact passivating monolayers are formed on the (111) and (100) facets of the nanocrystallites, with adsorption site geometries differing from those found on extended flat Au(1...

This review describes the progress of the development of surface chemical reactions for themodification of self-assembled monolayers (SAMs) and the fabrication of surface chemical gradients. Various chemical reactions can be carried out on SAMs to introduce new functionalities. “Click” reactions, which are highly efficient and selective, have largely contributed to the development and implement...

Nanosized noble metal catalysts supported on high-surface-area support are of great importance for numerous industrial chemical processes to mediate reaction pathways in heterogeneous catalysis. Control of surface area and surface energy of nanocatalysts is a key to achieving high activity and selectivity for desired products. In the past decade, new synthetic methodologies for noble metal nano...

Surface relief formed by nanoimprinting and etching into a thermally grown SiO2 layer on Si was used to position the initial nuclei formed by chemically vapor deposited Si and Ge. By controlling the deposition conditions, the surface diffusion length was adjusted to be comparable to or larger than the spacing between features, thus favoring nucleation adjacent to steps, rather than random nucle...

By the introduction of an organic silane self-assembled monolayer, an interface-engineering approach is demonstrated for hole-conductor-free, fully printable mesoscopic perovskite solar cells based on a carbon counter electrode. The self-assembled silane monolayer is incorporated between the TiO2 and CH3NH3PbI3, resulting in optimized interface band alignments and enhanced charge lifetime. The ...
