Semiconducting, Magnetic or Superconducting Nanoparticles encapsulated in Carbon Shells by RAPET method.
Journal Title: Carbon - Science and Technology - Year 2008, Vol 1, Issue 1
Abstract
An efficient, solvent-free, environmentally friendly, RAPET (Reactions under Autogenic Pressure at Elevated Temperature) synthetic approach is discussed for the fabrication of core-shell nanostructures. The semiconducting, magnetic or superconducting nanoparticles are encapsulated in a carbon shell. RAPET is a one-step, thermal decomposition reaction of chemical compound (s) followed by the formation of core-shell nanoparticles in a closed stainless steel reactor. The representative examples are discussed, where a variety of nanomaterials are trapped in situ in a carbon shell that offers fascinating properties.

Methane storage in a commercial activated carbon
A commercial activated carbon was examined for possible methane storage application. The structural and surface properties of the carbon were characterized by Nitrogen adsorption isotherm at 77 oK. It was found that the...
Oxygen reduction activity of carbon fibers cathode, and application for current generation from the NAD+ and NADH recycling reaction
Carbon fibers treated at 700 oC for 10 min. were found to have O2 reduction activity when being used as a cathode. The special type of partition combined with both cationic and anionic exchange membranes was applied betw...
Is vacuum annealing converts p-type single wall carbon nanotube field effect transistor (in air) to n-type (in vacuum) is universially true (?)
Our study on nickel silicide and gold contacted single-wall-carbon-nanotube field effect transistors (SWCN-FETs) is in sharp contrast to earlier published reports of type conversion in SWCN-FETs (from p- to n-) when cycl...
Efficiency enhancement of wood stove integrated with catalytic combustor and modified chimney
Domestic wood combustion produces smoke that is harmful to human health and increases fine particle level in the atmosphere. Some necessary changes in the design are essential in the domestic wood stove in order to impro...
Preparation of iron doped carbon coated W18O49 and its photoactivity
Iron doping to carbon coated W18O49 was carried out through solid-state reaction of WO2.9 with iron acetate at 400oC, followed by carbonization with poly(vinyl alcohol) (PVA) as carbon precursor at 800oC in N2 atmosphere...
