ENHANCEMENT OF THERMAL CONDUCTIVITY OF ALUMINIUM BY DOPING GRAPHENE FOLLOWED BY MELTING AND CASTING PROCESS
The present invention relates to the process for enhancement of thermal conductivity property of aluminium up to 50 to 90% or more by doping graphene or reduced graphene of two to five layers into aluminium by melting and casting process under inert or vacuum or atmospheric condition using salt and flux. Graphene with purity of 70 to 90% was incorporated into aluminium of any form for 30 to 120 minutes under inert atmosphere or vacuum at 700-900 deg C. Graphene of 0.1 to 5% weight of the total weight of aluminium has been used in the process. Under optimum conditions enhancement of thermal conductivity up to 80 to 90% has been observed using this process.

Method for die casting an inner door panel for a vehicle side door
A method for manufacturing an inner door panel for a vehicle side door that employs a die casting process. The method includes providing a die cast mold having opposing mold halves that combine to define a die cavity configured to provide the inner door panel. An impact beam is positioned in the mold cavity prior to combining the first mold half and the second mold half, and a molten metal is provided to the mold cavity so that molten metal flows into all areas of the mold cavity and around the impact beam after the first mold half and the second mold half are combined. A solidified molded inner door panel is then removed from the die cast mold that includes an encapsulated impact beam.

CONDUCTIVE LIQUID THREE DIMENSIONAL PRINTER
A printer that produces objects from liquid conductive material is disclosed. In one embodiment, the print head has a chamber for containing liquid conductive material surrounded by an electromagnetic coil. A DC pulse is applied to the electromagnetic coil, resulting in a radially-inward force on the liquid conductive material. The force on the liquid conductive material in the chamber results in a drop being expelled from an orifice. In response to a series of pulses, a series of drops fall onto a platform in a programmed pattern, resulting in the formation of an object.
