Aluminum and its alloys have a lot of industrial applications due to their appropriate physical and chemical characteristics. However, those present a modest mechanical performance. One method to improve its strenght is the addition of hard insoluble particles as: carbides (Al4C3, TiC), oxides (Al2O3) or nitrides (TiN, AlN), which can difficult the dislocation movement at atomic level, resultin...

AMoO3–carbon nanocomposite was synthesized from amixture ofMoO3 and graphite by a controlled ball milling procedure. The as-prepared product consists of nanosized MoO3 particles (2–180 nm) homogeneously distributed in carbon matrix. The nanocomposite acts as a high capacity anode material for lithium-ion batteries and exhibits good cyclic behavior. Its initial capacity exceeds the theoretical c...

Abstract Screen-printing inks containing various morphologies of carbon are used in the production a variety printed electronics applications. Particle morphology influences rheology ink which will affect deposition and therefore electrical performance component. To assess effect both concentration on print topography conductivity, screen printable with differing loading concentrations graphite...

Apr i l 20 0 8 Graphene, a newly isolated form of carbon, provides a rich lode of novel fundamental physics and practical applications BY ANDRE K. GEIM AND PHILIP KIM C onsider the humble pencil. It may come as a surprise to learn that the now common writing instrument at one time topped the list of must-have, high-tech gadgets. In fact, the simple pencil was once even banned from export as a s...

Abstract In this work, we show evidence of enhanced photocatalytic activity in mechanically activated graphite-zinc oxide (ZnO) composites using time-resolved photoluminescence (TRPL) and time-integrated (TIPL) spectroscopy. The graphite-ZnO were synthesized through facile mixing grinding graphite ZnO precursors without any heat treatment. ground at room temperature with varying to mass ratios ...

A variety of strategies for the synthesis of solution processable graphene sheets has been developed so far. However, no approach has been reported to directly produce highly conductive, low-oxygen-containing graphene sheets without relying on toxic reagents and metal containing compounds and without generating toxic by-products. With an aim of developing such an eco-friendly approach, for the ...

Interfacial interactions between liquid-solid and solid-solid phases/surfaces are of fundamental importance to the formation of hydrate deposits in oil and gas pipelines. This work establishes the effect of five categories of physical and chemical modification to steel on clathrate hydrate adhesive force: oleamide, graphite, citric acid ester, nonanedithiol, and Rain-X anti-wetting agent. Hydra...
