AbstractIn this paper, we carry out numerical modeling of the magnetoplastic effect. The molecular-dynamics simulation of deformation processes in Cu–Ni metal alloys are performed, in order to clarify the mechanisms of the magnetoplastic effect, which has been experimentally observed in copper, titanium, aluminum and magnesium alloys. A numerical e...

AbstractThe state of the surface layer of polished silicon substrates and the effect of surface-cleaning procedures, such as washing in an ultrasonic bath, etching, and vacuum annealing, is studied. The X-ray reflectivity technique is used to determine the root-mean-square (rms) roughness, thickness, and density of the damaged surface layer. It is ...

AbstractThe results of studying the possibility of using a position-sensitive detector with a 100 × 100 mm 10B active layer to record thermal and fast neutrons are presented. The operation of the detector is explored using a tungsten-beryllium photoneutron source at the Institute for Nuclear Research, Russian Academy of Sciences. The low efficiency...

AbstractThe results of using resonance neutron scattering at Gd atoms for the experimental determination of complex reflection coefficient of metallic samples with ferromagnetic layers by neutron reflectometry are presented. A reference Gd layer is deposited onto the surface of the samples under study, for which the scattering length of slow neutro...

AbstractThe study of the influence of electron-beam treatment on the structural features of a TiNi powder alloy obtained by calcium-hydride reduction is carried out. It is found that electron-beam treatment leads to homogenization of the phase and chemical composition of the surface layer of the TiNi powder alloy, smoothing of the surface relief of...

Abstract—We report on a synthesis procedure for obtaining a UiO-66 metal-organic framework in the form of nanoparticles with a modified surface. A distinctive feature of the developed procedure is that modification occurs directly during synthesis. Biocompatible polyethylene glycol (PEG) is selected as the organic polymer covering the surface of th...

AbstractA structural study of graphene oxide complexes with detonation nanodiamonds (particle size 4–5 nm, positive surface potential) in aqueous suspensions by small-angle neutron scattering is reported. While the pure graphene oxide suspension exhibits a completely planar structure, the grafting of detonation nanodiamond particles results in a sl...

AbstractIn this paper the surface of diffusion filter membranes of alloy Pd–5.3 at %–In–0.5 at % Ru is studied by atomic force microscopy. This alloy is in demand in the diffusion separation processes of high-purity hydrogen. The surface of membranes is studied before and after hydrogenation. Prior to hydrogenation, it is determined that the surfac...
