A High-Throughput, Solvent Free Method for Dispersing Metal Atoms Directly onto Supports

Atomically-dispersed metal catalysts (ADMCs) on surfaces have demonstrated high activity and selectivity in many catalytic reactions. However, dispersing and stabilising individual atoms in support materials in an atom/energy-efficient scalable way...

Nikolay N. Semyonov: a prophet and a tamer of fire and atom energy

The paper is a memoirs of the Honoured scientist of the Russian Federation Konstan­tin M. Dolgov of his communication with Soviet Academy of Science member Nikolay N. Se­myonov – one of the founders of the physical chemistry and the only Soviet Nobel Prize winner in chemistry. The paper provides the analysis of the personality of this prominent scientist, his achievements and his views upon the development of science and interactions between different branches of science.

Электронно-стимулированная десорбция атомов цезия с графена на иридии, интеркалированного и не интеркалированого цезием

Electron stimulated desorption (ESD) of neutral atomic Cs from graphene on Ir has been studied for two cases: when Cs intercalation does present and when it does not take place. Two peaks have been found at desorbed atom energy distribution: high-energy (HE) at the energy of 0.36 eV and low-energy (LE) one at the energy of 0.13 eV. HE peak has been observed for both cases, we attribute it with excitation of 2s carbon core level. LE peak was observed only when intercalation does not take place; we attribute it with excitation of 4f and 5p core levels of Ir. A model is put forward to describe atomic Cs ESD; we proposed that graphene on Ir acts as dielectric in the processes discussed above.
