Abstract: Various embodiments of the present invention are directed towards a system and method relating to depositing vapor in a sample. For example, a device includes a vapor source chamber configured to contain a vapor source material to generate vapor. An activation chamber is configured to contain a sample. The activation chamber is in fluid communication with the vapor source chamber to receive the vapor. A permeable separator divides the vapor source chamber and the activation chamber, and isolates the sample in the activation chamber while allowing vapor to pass between the vapor source chamber and the activation chamber. The device is sealable and configured to apply vacuum to the vapor and sample, to cause deposition of the vapor into the pumice stone samples.

Abstract: Embodiments include a system that may include a reactor including a reaction zone and a gas release zone separated by a selectively permeable membrane, wherein the selectively permeable membrane permits hydrogen to pass through the membrane and substantially blocks a substrate and its dehydrogenative coupling product from passing through the membrane. Embodiments further include a method of producing a dehydrogenative coupling product, wherein the method may include exposing a substrate to a catalyst in a reaction zone of a reactor; coupling the substrate to form the dehydrogenative coupling product and hydrogen; and separating the hydrogen from the dehydrogenative coupling product using a selectively permeable membrane and passing the hydrogen to a gas release zone of the reactor.

Abstract: The present disclosure provides a reactor and a method for the production of high purity silicon granules. The reactor includes a reactor chamber; and the reaction chamber is equipped with a solid feeding port, auxiliary gas inlet, raw material gas inlet, and exhaust gas export. The reaction chamber is also equipped with an internal gas distributor; a preheating unit; and an external exhaust gas processing unit connected between the preheating unit and a gas inlet. The reaction chamber is further equipped with a surface finishing unit, a heating unit, and a dynamics-generating unit. The reaction occurs through decomposition of silicon-containing gas in a densely stacked, high purity granular silicon layer reaction bed in relative motion, and uses the exhaust gas for heating. The present invention achieves a large-scale, efficient, energy-saving, continuous, low-cost production of high purity silicon granules.

Abstract: Disclosed is a technology based upon the nesting of tubes to provide chemical reactors or chemical reactors with built in heat exchanger. As a chemical reactor, the technology provides the ability to manage the temperature within a process flow for improved performance, control the location of reactions for corrosion control, or implement multiple process steps within the same piece of equipment. As a chemical reactor with built in heat exchanger, the technology can provide large surface areas per unit volume and large heat transfer coefficients. The technology can recover the thermal energy from the product flow to heat the reactant flow to the reactant temperature, significantly reducing the energy needs for accomplishment of a process.
