explains the efffects of Ce content on the properties as well as on the formed morphologies and scales.

The morphological features of the structures of the adsorbed substance on the surface of freshly cleaved mica in contact with the three-component water-surfactant-oil system were studied using atomic force microscopy. The mechanism of adsorption of anionic surfactants on the mica surface in the presence of cations in solution has been confirmed.

The effect of exposure (30, 60, and 120 min) during the processing in the low-pressure non-self-sustained arc discharge plasma on microstructure and phase composition of the modified surface layers obtained in a Ti-6Al-4V alloy with a preliminary deposited Al coating has been evaluated.

The difference between the mechanisms of crystallization of nanoparticles upon cooling from the melt and upon heating from low temperatures during devitrification is studied

Thin film with antidote lattice.

Mechanical properties, corrosion resistance and biocompatibility in vitro of pure Zn processed by high pressure torsion (HPT) were studied. Grain refinement and texture changes caused by HPT increase strength and ductility. HPT does not worsen the RBC hemolysis and ML viability of pure Zn. HPT insignificantly increases the degradation rate.

It has been established that the localization of crystalline LaB6 nanoparticles determines the work function of the hybrid carbon nanomaterial single-walled nanotubes/graphene. As the mass fraction of LaB6 nanoparticles increases, the work function decreases.

3D view of topological charge phase diagram. Axes are parameters of exchange and magnetoelectric interaction, height is absolute value of topological charge in ground state.

1. A theoretical study of new autointercalated carbon compounds formed from hexagonal graphyne layers has been performed. 2. The most stable nanostructured materials should be composed of autointercalated alpha-graphyne-1. 3. A porous orthorombic three-dimensional phase can be obtained on the basis of alpha-graphyne-1.

Grain fragmentation in tensile strained copper is orientation dependent

Elements composition and coating mechanism formation on WC-8%Co and WC-15%TiC-6%Co hard alloys

Crystallographic texture is an important characteristic of all anisotropic polycrystalline materials. The formation of recrystallization texture in Russian zirconium alloys is analyzed using Debye rings obtained by shooting with a synchrotron beam, the traditional X-ray method, and backscattered electron diffraction.

Microstructure of solid-state joint of dissimilar EK61 and EP975 Ni-based superalloys after pressure welding as well as following heat treatment.

The Ti-50.8 at.% Ni (TiNi) medical alloy wire samples with bioinert PVD-coatings of different compositions were studied. The elastic-force characteristics (phase yield strength σM, mechanical hysteresis value ΔH, residual deformation εres, and unloading plateau stress σc) of TiNi have been studied based on the stress-strain curves obtained at different temperatures (5°С, 19°С, 37°С, and 60°С).

The typical macrostructure of the AK4-1 aluminum alloy with local mixing of the AK12D alloy into it via friction stir processing

The inter-fragment boundary misorientation distributions are close at two temperatures of deformation, except for the high-angle peak associated with the twinning at 0.5Tm (Tm is the melting temperature of copper).

In niobium filaments of the Cu-7.7%Nb composite under cold-drawing beginning from the true strain of 8.5, macrostrains are observed according to the X-ray data, which is confirmed by TEM data, which demonstrate distortions of niobium lattice and formation of partially coherent boundaries (110)Nb || (111)Cu. These macrostrains are anisotropic and higher than those in the Cu-18%Nb composites.

Antibacterial nanospike morphology on nanostructured titanium obtained by Ar bombardment

The geometric scheme illustrates changes in size of coordination tetrahedron in ZnSxSe1-x substances diluted by 3d-impurity. Neutron-diffraction characterization of structure instability of ZnSxSe1-x:M (M=3d-ions) solid solutions are presented in the article.

Non-linear volt-current dependences with a zero current area have shown their ties with the structural state of carbon surface layer formed by 2-3 graphene planes assembled in an onion-shaped structure with these planes disoriented with respect to each other so that their new positions differ from the positions in the ideal graphite crystal.
