AbstractThe results of an experimental study of the interfacial tension and surface wettability in the nanosuspension/oil/rock system are given. The effect of the concentration and size of silicon oxide nanoparticles on the coefficient of interfacial tension and the contact angle of wetting has been systematically studied for the first time. A wide...

AbstractWe have studied the growth of GaN layers by the metalorganic vapor phase epitaxy (MOVPE) on sapphire substrates at various reactor pressures, including ones above the atmospheric level. It is established that the epitaxial growth at higher pressures does not affect the crystalline perfection of epilayers, their electron mobility, and backgr...

AbstractImprovement of physical and mechanical characteristics of mineral-filled polyethylene (MFPE) upon addition of alumina nanofibers with a high aspect ratio has been experimental studied. It is shown that, at the weight concentration of alumina nanofibers of 0.1 wt %, the ultimate tensile strength increases from 3.82 ± 0.04 to 6.70 ± 0.07 MPa ...

AbstractWe have studied the luminescent properties of zinc oxide (ZnO) films on a rhombohedral plane of sapphire with a buffer layer of gold nanoislands. The luminescence spectrum revealed a set of oscillations caused by the classical interference in the thin ZnO film. This set can be represented by a bar code in which every bar corresponds to the ...

AbstractWe analyze the possibility of generating pulses of superradiance in the terahertz range during the concurrent scattering of a laser pulse by a high-current relativistic electron beam with frequency conversion downward. The scattered radiation propagates in the opposite direction (with respect to the translational velocity of the particles)....

AbstractMetal–ferroelectric–semiconductor Pb(ZrTi)O3/Ba0.2Sr0.8TiО3/Si(001) heterostructures have been synthesized by radiofrequency cathode sputtering. It has been established that the Pb(ZrTi)O3 films are single-phase and textured and the degree of predominance of one crystallographic orientation over another (110 or 001) is determined by the Ba0...

AbstractHigh-speed photodetectors (PDs) based on InGaAs/GaAs quantum well-dot (QWD) nanostructures with the frontal-end and back-end input of radiation have been studied. A PD with 40 rows of QWDs exhibited a spectral responsivity of up to 0.4 A/W in the 950–1100 nm optical range at a –5-V bias voltage. The decay time constant of pulsed response fo...

AbstractThe spectrum of slow electromagnetic waves (EMWs) existing in a left-handed medium based on a magnetoactive plasma metamaterial has been theoretically studied. The metamaterial under study is a strip waveguide completely filled with longitudinally magnetized cold electron plasma containing a periodic structure made from ideally conducting s...

AbstractThe nature of changes in laser photoacoustic signals near small-diameter holes in aluminum and steel layers in a bimetallic plate obtained by hot rolling is investigated. The experimental results are compared with the solution of the classical Kirsch problem for stress distribution around a circular hole in a prestressed material. The possi...

AbstractPeculiarities of the motion of one and two supercavitating strikers in water upon their simultaneous entry into water at speeds exceeding the speed of sound in the medium are considered. Conditions have been developed to ensure nondestructive entry of strikers into the water and stable movement along an aiming trajectory in the transonic sp...
