Diffusional interaction and phase formation in nickel–aluminum films [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2017 In the present paper bimetal nickel –aluminum films are obtained in vacuum by method of the contact melting at temperature 650°C. The eutectic formations which appear on the surfaces of the films due to diffusion are detected by method of the raster-type

Gas Phase Formation of Methylgermylene (HGeCH3)
ChemPhysChem, 2020 AbstractThe methylgermylene species (HGeCH3; X1A′) has been synthesized via the bimolecular gas phase reaction of ground state methylidyne radicals (CH) with germane (GeH4) under single collision conditions in crossed molecular beams experiments. Augmented by electronic structure calculations, this elementary reaction was found to proceed through ...
