inert annealing of irradiated graphite by inductive heating

Production of Graphite Chloride and Bromide Using

The decrease in chlorine content on heating (see above) shows that the structure of graphene chloride can be recovered by annealing at high temperature. Consistent with this, the Raman spectrum of annealed G–Cl shows a higher D/G intensity ratio than that for G–Cl, which is indicative of the creation of numerous new graphitic domains that are smaller in size than the ones present in

Stored energy release behaviour of disordered carbon,

The use of graphite as a moderator in a low temperature thermal nuclear reactor is restricted due to accumulation of energy caused by displacement of atoms by neutrons and high energetic particles. Thermal transients may lead to a release of stored energy that may raise the temperature of the fuel clad above the design limit. Disordered carbon is thought to be an alternative choice for this

Carbon Felt

Carbon felt and graphite felt are designed for use as high temperature insulation in vacuum furnaces and inert gas furnaces. The needle-punched PAN based carbon and graphite felt is light in weight and has low thermal conductivity. It can be used in oxidizing temperatures up to 400 C and in vacuum or protective atmospheres up to 3200C Thermal properties of carbon felt: Low thermal

Solid State Phase Transition of Nanodiamond upon

Annealing of an irradiated sample of a detonation nanodiamond by fast neutrons led to the release of Wigner energy in the temperature range from 230 to 450 C. And with an increase in the exposure time of the neutron beam to the sample, the amount of energy released during subsequent annealing in an inert atmosphere increased [4].

Magnetism of FePt Nanoclusters in Polyimide

FePt nanoclusters have been implanted onto polyimide films and subjected to thermal annealing in order to obtain a special magnetic phase (L1sub0/sub) dispersed within the polymer. SQUID measurements quantified the magnetic features of the as-prepared and annealed hybrid films. As-implanted FePt nanoparticles in polyimide films exhibited a blocking temperature of 70 #xb1;

Nanopatterning of Fluorinated Graphene by Electron Beam

We demonstrate the possibility to selectively reduce insulating fluorinated graphene to conducting and semiconducting graphene by electron beam irradiation. Electron-irradiated fluorinated graphene microstructures show 7 orders of magnitude decrease in resistivity (from 1 TΩ to 100 kΩ), whereas nanostructures show a transport gap in the source–drain bias voltage. In this transport gap
