The enhancement of the dimer formation (which has an important role in carbon plasma chemistry) in the lateral structures is confirmed and even amplified by the use of background gas. Furthermore, temperature and electron density values have been estimated from the spectroscopic data, providing ...
A single layer of carbon atoms arranged in such a honeycomb structure forms a single graphene sheet. Several sheets stacked one on top of the other are regarded as multi-layer graphene, up to the point where the material becomes graphite (usually over about 30 layers, although clear standardiza...

One of the reasons why nanoparticles are so interesting is the fact, that the active surface area increases with the decrease of the particle size. In other words, it is possible to synthesize catalysts with a high activity using a relatively little amount of active metal1. This is especially...

Carried out in relfexion, a graphite secondary monochromator was used before the scintillation counter, which was used to detect the signal. KPFM measurements for all samples were carried out on an MFP 3D AFM (Asylum Research/Oxford Instruments, Santa Barbara, CA, USA) in a nitrogen-filled ...

The simplest way to describe graphene is that it is a single, thin layer of graphite — the soft, flaky material used in pencil lead. Graphite is an allotrope of the element carbon, meaning it possesses the same atoms but they’re arranged in a different way, giving the material differe...
Printed in Great Britain. @ 1989 IUPAC Clay minerals as selective and shape-selective sorbents R.M. Barrer Chemistry Department, Imperial College, London, SW7 ZAZ, England Abstract - An account has been given of four modes of sorption based on clay minerals and their cation exchanged and ...
graphite nanoparticles. However, analyzing nanoparticles' motion state and tribological properties in actual production is challenging because their size covers the micro-nano scale. In recent years, many researchers have used molecular dynamics (MD) simulations to quantitatively calculate tribological ...
