Abstract: An article comprises a heat source, a heat sink, and a high-efficiency diamond material interposed between and thermally coupled to the heat source and the heat sink. The heat source and the high-efficiency diamond material have a contact area greater than 1 square centimeter.

Abstract: A diamond foam article comprises diamond deposited material on a substrate having an open contiguous structure at least partially filled with a filler material. Methods for forming a diamond foam article comprise providing a foam substrate; preparing the foam substrate for diamond deposition; depositing diamond material on the foam substrate by one of several diamond deposition methods; and at least partially filling the diamond foam article with a filler material. Diamond foam articles are bonded to other components.

Abstract: A heat pipe has at least one diamond element through which at least a portion of heat flowing into the heat pipe passes.

Abstract: A diamond foam article comprises diamond deposited material on a substrate having an open contiguous structure that permits the flow of fluids in at least one direction through the material. Methods for forming a diamond foam article comprise providing a foam substrate; preparing the foam substrate for diamond deposition; and depositing diamond material on the foam substrate by one of several diamond deposition methods.

Abstract: A method for making diamond material comprises providing a deposition chamber; placing a substrate in said deposition chamber; sealing and evacuating said deposition chamber; admitting to said deposition chamber gases suitable for diamond deposition; heating said substrate to a diamond deposition temperature; igniting and maintaining a plasma adjacent to a growth surface of said substrate such that said plasma extends no further than 1 mm from said growth surface of said substrate; and maintaining said plasma during a diamond deposition time period.
