The graphical abstract shows Young's modulus and strength of Ni with monolayer and multilayer graphene, as well as snapshots of the structures under uniaxial tension.

Frequency dependences of Fe films (SAS·HCl) at different times of their formation t (days): 1 – 1 day, 2 – 3 days, 3 – 5 days. Pressure P=104Pa.

Structure of a photoresistor with a film of a polyaniline derivative.Oxidative polymerization of 2-(1-methylbut2-en-1-yl)aniline.

Ultra-high frequency acoustic oscilations of main gas pipeline wall are one of the causes of stress corrosion of the metal pipeline

A material with a gradient porous structure was produced by the method of layer-by-layer deposition of the powder mixtures. Permeability of materials with gradient porous structure was increased by 30 – 57 % due to the use of the coarse porous layer.

Compared with traditional annealing without a field, unsaturated magnetic field annealing leads to a more significant improvement in the soft magnetic properties of an amorphous alloy with a higher Ni content.

A comparison of results between high pressure torsion (HPT) experiments with transformation the layered Cu-Ta composites into metal matrices one.

The stress-induced martensite formation depends on the strain rate. A higher strain rate results in a lower proportion of stress-induced martensite.

Dilatograms of PT-3V SLM-specimen and a rod.

Scheme of pressure welding and solid-state joint of heat-resistant nickel-based EK79 and EP975 superalloys.

Some areas consisting of two layers free of microcracks have been found in the structure of the coatings (Fig. 1). The lower layer - points (3 – 5) contains an increased concentration of Fe (~ 17-47 at.%). The (Fe) concentration in the crystallites of the upper layer (points 6 – 9) does not exceed 5 at.%, which is adequate to its content in crystallites in the areas with microcracks (Fig. 2). The lower layer of a two-layer coating due to its higher ductility acts as a barrier preventing the occurrence of microcracks at a sufficiently high Fe content (more than 14 wt.%).

Our study is the first to demonstrate that lanthanum, even in small quantities, being part of the Al–Ca–La complex eutectics, has a decisive influence on the microstructure formation and mechanical properties of Al–Ca alloys.
