The paper presents the main findings of the investigation into the potential of using detonation nanodiamonds and diamond-containing soot (an intermediate product of the nanodiamond synthesis) as high-performance antifriction and wear-preventive additives to oil-based compounds. The application of these products is de…
At Physikalisch-Technische Bundesanstalt, the National Metrology Institute of Germany, a new type of deep ultraviolet scatterometer has been developed and set up. The concept of the system is very variable and versatile, so that many different types of measurements, e.g., classical scatterometry, ellipsometric scatter…
Problem statement: Researches has been conducted worldwide on a large number of natural or artificial lightweight aggregates. In spite of many of the researches of using natural fibers show considerable promise, the use of natural fibers to improve the properties of lightweight concrete still required to be a subject…
The influence of the composition on the crystallographic properties of deposited Mg(M)O (with M=Al, Cr, Ti, Y, and Zr) films is studied. For a flexible control of the composition, dual reactive magnetron sputtering was used as deposition technique. Two different approaches to predict the composition are discussed. The…
BACKGROUND: Liposomes have been successfully used as delivery vehicles for anticancer drugs. Both sonication and microfluidic technologies have been used to produce liposomes. The combination of the two methods was evaluated in this study. MATERIALS AND METHODS: The microfluidic devices, mainly comprising micro-dispen…
The Aldol condensation of furfural (Fur) with acetone (Ac) to 4-(2-Furyl)-3-buten-2-one (FAc) is one of the most important processes in the aqueous-reforming of oxygen-containing biomass derivatives and has been carried out in the presence of solid-base catalysts, calcined-rehydrated Layered Double Hydroxides (LDH). T…
The substrate-induced strain effect in La7/8Sr1/8MnO3 (LSMO) thin films grown on (001)-oriented SrTiO3 and ferroelectric 0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN-PT) substrates was investigated. A metal-insulator transition was observed at low temperature in LSMO/PMN-PT, which was ascribed to charge/orbital ordering (COO) f…
The world scientific community is presently engaged in one of the toughest technological tasks of the current century, namely, exploitation of nuclear fusion in a controlled manner for the benefit of mankind. Scientific feasibility of controlled fusion of the light elements in plasma under magnetic confinement has alr…
Abstract— The flexoelectro‐optic effect provides a fast‐switching mechanism (0.01–0.1 msec), suitable for use in field‐sequential‐color full‐motion‐video displays. An in‐plane electric field is applied to a short‐pitch chiral nematic liquid crystal aligned in the uniform standing helix (or Grandjean) texture. The swit…
This paper characterizes the inhomogeneous rare earth activator distribution across grain boundaries in transparent rare earth doped optical ceramics. Ce 3+ has been selected due to its high intensity fluorescence in visible range under blue or UV excitations, especially in (Gd,Y) 3 Al 5 O 12 disordered garnet ceramic…
In this paper, we reported a Raman scattering study of epitaxial graphene on different doped 6H-SiC (0001) substrates and investigated the substrate induced charge-transfer doping to the epitaxial graphene. We found that the charge carrier type and concentration of epitaxial graphene can be altered by SiC substrates w…
Pure cobalt titanate nanopowders were successfully prepared in wet-chemistry synthesis method, using cobalt acetate and tetra-n-butyl titanate as Co and Ti sources and stearic acid as complexing reagent. The gel was calcined at different temperatures in air ranging from 500°C to 650°C. Results of thermal analysis are…
Features associated with the cross relaxation between spin of the ground electric state of the nitrogen vacancy centre (NV) and other impurity spins, mainly substitutional nitrogen, NS, are observed as changes of the emission intensity as a function of external magnetic field. The features are attributed to NV-NV elec…
Mn and Cr-doped In2O3 films with Sn codoping were deposited on sapphire substrate by pulsed laser deposition. The ferromagnetism of Mn-doped In2O3 films shows reversible behavior, which can be switched between “on” and “off” states by controlling the carrier density via varying Sn concentration. The enhanced ferromagn…
Polymer/ceramic composite films with micro- and nanocombined hierarchical structures are fabricated by electron irradiation of poly(methyl methacrylate) (PMMA) microspheres/silicone grease. Electron irradiation induces volume contraction of PMMA microspheres and simultaneously transforms silicone grease into a ceramic…
The thermal rectification (TR) effect in a topological system, Möbius graphene strip, is studied by nonequilibrium molecular-dynamics simulation with Nóse-Hoover heat baths. Due to the nonlinear interaction in graphene and the topological asymmetry of the Möbius strip, the TR phenomenon emerges and the value of TR can…
The magnetic properties of La1−xCaxMnO3 (x=0.50, 0.67, and 0.75) nanoparticles have been systemically investigated in this work. It is found that although their bulk counterparts have different magnetic and charge ordered states, the nanoparticles show no long-range charge ordered transition but very similar magnetic…
The impact failure characteristics of rock subjected to one-dimensional coupled static and dynamic loads are conducted with a modified split Hopkinson pressure bar(SHPB). Firstly,the testing principle with axial precompression stress is re-examined based on one-dimensional wave theory. The axial precompression stress(…
Epitaxial Na0.5Bi0.5TiO3 thin films presenting various thicknesses were grown by pulsed laser deposition on epitaxial (100) platinum bottom layers supported by (100)MgO single crystal substrates. X-ray diffraction data indicated that all Na0.5Bi0.5TiO3 layers are single-phased and that (100)-oriented Na0.5Bi0.5TiO3 (N…
We study theoretically the nonlinear response properties of glass formers. We establish several general results, which together with the assumption of time-temperature superposition, lead to a relation between the nonlinear response and the derivative of the linear response with respect to temperature. Using results f…
