Shock formation in electron-ion plasmas: mechanism and timing [PDF]
, 2015 We analyse the full shock formation process in electron-ion plasmas in theory and simulations. It is accepted that electromagnetic shocks in initially unmagnetised relativistic plasmas are triggered by the filamentation instability.

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 ...

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

Entropy-driven formation of the gyroid cubic phase [PDF]
, 2006 We show, by computer simulation, that tapered or pear-shaped particles, interacting through purely repulsive interactions, can freely self-assemble to form the three-dimensionally periodic, gyroid cubic phase.

Eutectic colony formation: A phase-field study [PDF]
Physical Review E, 2002 Eutectic two-phase cells, also known as eutectic colonies, are commonly observed during the solidification of ternary alloys when the composition is close to a binary eutectic valley. In analogy with the solidification cells formed in dilute binary alloys, colony formation is triggered by a morphological instability of a macroscopically planar eutectic

A sparsity-driven approach for joint SAR imaging and phase error correction [PDF]
, 2012 Image formation algorithms in a variety of applications have explicit or implicit dependence on a mathematical model of the observation process. Inaccuracies in the observation model may cause various degradations and artifacts in the reconstructed ...

Influence of the parameters of thermal decomposition of ammonium tetravanadate on the processes of phase formation of highly dispersed vanadium oxides. [PDF]
Trudy Odesskogo Politehničeskogo Universiteta, 2018 The peculiarities of the thermal decomposition of the highly dispersed vanadium (IV) ammonium tetrabutanate salt, which is a precursor for the production of nanocrystalline vanadium oxides of different degrees of oxidation (V2O5, VO2), are studied.
