Abstract: Process and apparatus for functionalizing and/or separating graphene particles and other nanomaterials in which graphene and other nanoparticles are placed in a pile on one of two opposing conductive surfaces that are charged with a high D.C. voltage so that material of a certain character is attracted to the other conducting surface. This process takes place in an enclosed chamber that has been flooded with a designated gas at ambient pressure, with the material attracted to the second conducting surface passing through the designated gas. The high energy field creates a condition such that the material remaining on the first conductive surface takes on atoms of the designated gas and material the going to the second surface is further exposed to and characterized by the designated gas.

Abstract: Graphene composite material and devices using the same. The graphene is dispersed in material such as polyurethane, latex, other elastomers, and other polymers to produce a composite material having high heat transfer properties which make it particularly suitable for use in removing heat from LEDs and other electronic devices. Several examples of heat transfer devices utilizing the material are disclosed.

Abstract: An automated, computer-controlled landfill gas recovery system includes a number of equipment vaults, with each vault being associated with one or more wells in the landfill. The wells are in fluid communication with a piping system located in the associated vault, with the piping system including a main pneumatic control valve that can be adjusted to establish gas flow rate through the well or wells. Also, each vault includes a shielded enclosure that holds sensors and a local vault controller for generating signals representative of flow rate, vacuum, and oxygen/methane/carbon dioxide content of the gas being extracted from the well. These signals are sent to a remote computer. Based on the signals generated by the sensors, the computer communicates with each vault controller to control the pneumatic control valve of each vault to establish a gas flow rate from the associated well as appropriate to accord with one of several user-selected process control regimes.
