Patent number: 8753525Abstract: A microporous carbon matrix material composition for use in supercapacitor electrodes may be produced by depositing carbon on a sacrificial zeolite template via one of several methods (e.g., hydrothermal or solvo-thermal deposition, sub-atmospheric vapor phase deposition, or high-pressure infiltration of hydrocarbon vapors). The deposition produces a carbon-coated zeolite intermediary. A surface layer of carbon formed on the carbon-coated zeolite intermediary may then be refined and the refined carbon-coated zeolite intermediary may be etched to produce a microporous carbon matrix having a substantially uniform structure and substantially aligned pores. In some embodiments, the carbon-coated zeolite intermediary may be annealed after deposition.Type: GrantFiled: February 28, 2013Date of Patent: June 17, 2014Assignee: Sila Nanotechnologies Inc.Inventor: Gleb Nikolayevich Yushin

Patent number: 8741158Abstract: An article having a nanostructured surface and a method of making the same are described. The article can include a substrate and a nanostructured layer bonded to the substrate. The nanostructured layer can include a plurality of spaced apart nanostructured features comprising a contiguous, protrusive material and the nanostructured features can be sufficiently small that the nanostructured layer is optically transparent. A surface of the nanostructured features can be coated with a continuous hydrophobic coating. The method can include providing a substrate; depositing a film on the substrate; decomposing the film to form a decomposed film; and etching the decomposed film to form the nanostructured layer.Type: GrantFiled: October 29, 2010Date of Patent: June 3, 2014Assignee: UT-Battelle, LLCInventors: Tolga Aytug, John T. Simpson, David K. Christen
