Interaction between two surfaces in relativemotion can give rise to energy dissipation and hence sliding friction. A significant portion of the energy is dissipated through the creation of non-equilibrium phonons. Recent advances in material synthesis have made the production of specific single layer honeycomb structures and their multilayer phases, such as graphene, graphane, fluorographene, M...

Diamond has poor interface tolerance with Al. To enhance bonding, in this study, tungsten carbide (WC) nanocoatings on the surface of diamond particles were prepared using sol–gel and in-situ reaction methods. WO3 two concentrations, 0.2 mol/L, 0.5 was, respectively, coated particles, then sintered at 1250 °C for 2 h to produce WC nanocoatings. The concentration mol/L was not enough cover compl...

We report on the fabrication, the characterization, and the optical simulation of a gold-silica nanocomposite and present its integration into a broadband anti-reflective coating (ARC) for a silicon substrate. The two-layer ARC consists of a nanocomposite (randomly distributed gold cluster in a silica matrix) and a pure silica film. We capitalize on the large refractive index of the composite t...

Free-radical polymerization inside mesoporous silica has been investigated in order to open a route to functional polymer-silica composite materials with well-defined mesoporosity. Various vinyl monomers, such as styrene, chloromethyl styrene, 2-hydroxyethyl methacrylate, and methacrylic acid, were polymerized after impregnation into mesoporous silicas with various structures, which were synthe...

In recent years, pseudocapacitors have been receiving much attention as low-cost and safe energy storage technology for emerging applications in flexible devices. However, creating high-energy-density electrode materials is now the main limit high-performance pseudocapacitors. this work, we propose a novel reduction route synthesis of uniform MnO2 nanocoating with porous morphology on nickel fo...

The present work is devoted to the experimental determination of uniformity ion flux density on a substrate with an increased size (~200 cm2 ) in order form nanostructures by laser-plasma method. system for deposition consists erosion laser torch target material and located vacuum chamber. For smooth adjustment parameters deposited particles substrate, grid between which negative potential appl...
