Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm·sup·3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm.sup.3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine.

Abstract: Systems, methods, and computer media for implementing a video game platform based on video game state data are provided herein. A system can include a processor, a data store, an intake coordinator, and a distribution coordinator. The data store can be configured to store video game state data for different video game play sessions. The intake coordinator can be configured to receive video game state data representing a video game environment over a period of time while a video game is being played by a first user. The video game state data can include frames having time stamps. Some of these frames can be designated as key frames that contain sufficient information to recreate the video game environment at a specific time. A distribution coordinator can be configured to transmit the video game state data to a requesting client, and the requesting client can recreate the video game environment.

Abstract: A semiconductor or similar body used, for example, for a solar cell is examined for the physical locations of characteristics effecting its performance, such as grain boundaries, areas of relatively higher sheet resistance, bulk resistance, shortened carrier lifetime, etc. A grid array layout for conductive lines may be specifically tailored such it is positioned over less efficient photo-generative regions of the body to, for example, minimize shadowing of more efficient regions, provide a short conduction path for regions of shortened carrier lifetime, etc. The grid array layout may then be formed on the surface of the body, for example by a digital lithographic process, to accommodate cell-by-cell and/or body-by-body variations in the performance characteristics. The tailored grid array provides increased overall photo-generative efficiency of the completed solar cell.
