A review on corrosion protection with single-layer

AbstractIn this review, most of the works are attempted to cover about corrosion protection of metals with molecular-tight atomic thin carbon layers of all sorts of graphene derivatives from the very beginning to the latest theoretical and experimental research findings, so as engineering achievements in the field up to date. Although high and tuneable electrical conductivity of graphene is

Synthesis and surface functionalization of silica

Most of the synthetic techniques employ sol-gel processing at 25 °C with careful control of the reactant to solvent ratios or the use of templates so as to control particles sizes. Mesoporous silica nanoparticles can be synthesized by modifying the Stöber process with added Fine synthetic control resulting in high surface areas,

Nitrogen-doped mesoporous carbon of extraordinary

2015-12-19 · In contrast to batteries, capacitors typically can store less power, but they can capture and release that power much more quickly. Lin et al. fabried a porous carbon material that was then doped with nitrogen. This raised the energy density of the carbon more than threefold—an increase that was retained in full capacitors, without losing their ability to deliver power quickly.
