Abstract: A quartz glass container is shown and described herein. The quartz glass container exhibits a low concentration of surface defects on an inner surface of the container. In aspects hereof, the container may have a surface defect density of 50 or fewer surface defects per square centimeter within a 1 cm band centered 1 cm from the base of the container.

Abstract: The present technology provides a non-cylindrical structure for transporting media, including gases, liquids, solids, or energy comprising a layer of thermal pyrolytic graphite (TPG) surrounded by an outer layer and an inner layer comprising a metal, a ceramic, a glass, or a plastic. In particular, the present technology relates to a non-cylindrical tube or a pipe having an inner layer, an outer layer, and a layer of TPG between the inner layer and the outer layer wherein the TPG layer is configured to manage the direction of heat conduction.

Abstract: A thermal management assembly comprising a bulk graphene material and a metal-based coating layer disposed on opposing surfaces of the bulk graphene core material comprising an agent that is reactive with the graphene to form a carbide. The metal-based coating layer can serve as an outer layer of the assembly or can serve to bond the graphene to other materials encapsulating the graphene core. The metal-based coating layer with the reactive agent provides an assembly exhibiting excellent thermal conductivity properties and greatly improved thermal interface resistance.
