Meta-surfaces are planar structures that locally change polarization, phase, and amplitude of light, thus enabling flat, lithographically patterned free-space optical components with functionalities controlled by design. Several types of meta-surfaces have been reported, but low efficiency and the inability to provide…

In search for the origins of the extraordinary low twinning stress of Ni-Mn-Ga magnetic shape memory alloys we studied the thermally induced changes of structure in Ni$_{50}$Mn$_{25+x}$Ga$_{25-x}$ ($x$=2.7--3.9) single crystal samples and compared them with twinning stress dependences. The alloys exhibited transformat…
We study a diffuse interface model for incompressible isothermal mixtures of two immiscible fluids coupling the Navier--Stokes system with a convective nonlocal Cahn--Hilliard equation in two dimensions of space. We apply recently proved well-posedness and regularity results in order to establish existence of optimal…

On the basis of the analysis of determination ways of thermal charge carriers capture cross section by defect from DLTS spectra the possible causes of essential measurement errors of the given parameter are revealed. The applicability borders of each way on a number of criteria — the characteristics of the investigate…
The influence of aluminum ions on requirements of plants of cereal crops (wheat Triticum aestivum L. and oats Avena sativa L.) in macronutrients is studied. In the first series of experiments it is revealed that doubling of a dose of phosphorus in the acid media has caused doubling of its inclusion in metabolic proces…
Abstract : Equipment Purchase - A Q-sense E4 Auto Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) with was bought to support DoD-relevant research on structural proteins, molecular interactions and surface science in general. The equipment included the following components: Complete Q-sense E4 Auto QCM…
Flying particles with visible fluorescence were observed when a target, ZnF 2 :Tm 3+ /Yb 3+ , was irradiated by using a 953.6 nm pulsed infrared laser.
In this paper, Y1 − x La x PO4:Eu3+ (x = 0.5, 0.7, and 0.3) nanophosphors were synthesized by a rather simple method. The products present different morphologies. For Y1 − x La x PO4:Eu3+, they have similar phase composition of a mixture of monoclinic LaPO4 and tetragonal YPO4. Furthermore, the luminescence behavior o…
There are many applications where compound materials can be of interest, for example when different properties are needed in different parts of a component. Compound materials can be produced by hot isostatic pressing (HIP) of powder metallurgical materials. One aspect that should be considered in the design is the qu…
We numerically study the splitting of light beam which carries orbital angular momentum (OAM) through single metal nano-scale hole. A light beam carrying with OAM has a helical phase distribution in the transverse plane, where the electric field has the form: E(r,θ)=E0exp(lθ), and l is the topological charge which den…
Heat loss in the heat supply systems of the Russian Federation reaches 300 million Gcal a year during transport. Excess heat loss is mostly due to the poor condition of the thermal insulation assemblies of pipelines and power equipment. Modern requirements for heat insulation coatings stipulate that they possess low t…
The interaction between adrenaline (Ad) and dibenzo-18-crown-6 (DB18C6) was studied by cyclic voltammetry, nuclear magnetic resonance spectroscopy, and the theoretical calculations, respectively. The results show that DB18C6 will affect the electron transfer properties of Ad. DB18C6 can form stable supramolecular comp…
To satisfy the high-stability requirement of a tiled grating, we have analyzed and optimized the stability of a newly designed precise tiledgrating device considering three aspects: structure design, transmission chain, and control algorithms. The main structure of the device is changed from a parallel-board structure…
Among ASCs, mesenchymal stem cells (MSCs), multipotent, represent a promising tool in clinical applications for their differentiative potential towards mesoderm-derived lineage (liver, kidney, muscle, epithelial, neuronal and cardiac cells)

Scattering of normally incident longitudinal and transverse acoustic waves by a randomly rough surface of an elastically isotropic solid is analyzed within the small perturbation approach. In the limiting case of a large correlation length $L$ compared with the acoustic wavelength, the specularity reduction is given b…
