Abstract: A process for producing silicon comprises the steps of a reduction step [1] of depositing silicon by reacting chlorosilanes and hydrogen in a reactor under heat and discharging an exhaust gas that contains hydrogen, oligomers of silanes, and a silicon powder; a carring step [2] of carrying the exhaust gas that has been exhausted in the step [1] while keeping a temperature of the exhaust gas at not less than 105° C.; a removal step [3] of supplying the exhaust gas that has been carried in the step [2] to a filter at a temperature of not less than 105° C. and discharging the exhaust gas from the filter at a temperature of not less than 105° C. to remove the silicon powder from the exhaust gas and give a mixed gas that contains the hydrogen and the oligomers of silanes; and a separation step [4] of cooling the mixed gas that has been obtained in the step [3] to separate the hydrogen as a gas phase from the mixed gas.

Abstract: An easy and controllable method and system to attach a carbon nanotube to a scanning probe tip such as a scanning probe microscopy (SPM) tip using a focus ion beam (FIB) technique. The method and system includes selecting a carbon fiber by a Focus Ion Beam micromanipulator, picking up the carbon fiber with the nanotube tip, forming a slot on an SPM tip, and inserting the carbon fiber with the nanotube tip into the slot.

Abstract: The invention relates to a process for the production of hydrogen peroxide comprising a liquid-liquid extraction step, said extraction step comprising contacting an organic feed solution containing hydrogen peroxide with an extraction solvent comprising less than about 30 wt % of water to achieve extraction of hydrogen peroxide to said extraction solvent and obtaining an extract containing hydrogen peroxide.

Abstract: An apparatus and process are presented that provide for the separation of hydrogen peroxide from a solution having an acid and hydrogen peroxide.

Abstract: The crude oil reserves have a time limit which may be calculated. Before the automobile industry, aviation, the weapons industry, and space travel change their combustion engines over to silanes, for example, hydrogen peroxide will preferably be used as an energy carrier. The hydrogen peroxide may be obtained especially advantageously from a power plant process according to the present invention, in which hydrocarbons contaminated with sulfur are used for combustion. The present invention also relates to a novel system for transporting/conveying hydrogen peroxide.

Abstract: A plasma reactor including a first dielectric having at least one slot defined therethrough, and a segmented electrode including a plurality of electrode segments, each electrode segment is disposed proximate an associated slot. Each electrode segment may be formed in different shapes, for example, a plate, bar, rim, or plug. The electrode segment may be hollow, solid, or made from a porous material. The reactor may include a second electrode and dielectric with the first and second dielectrics separated by a predetermined distance to form a channel therebetween into which the plasma exiting from the slots defined in the first dielectric is discharged. The fluid to be treated is passed through the channel and exposed to the plasma discharge. If the electrode segment is hollow or made of a porous material, then the fluid/gas to be treated may be fed into the slots defined in the first dielectric and exposed therein to the maximum plasma density.

Abstract: The present invention relates to simplified processes for the preparation of pure hydrogen peroxide (H2O2). H2O2 is a known oxidizer and disinfectant that is used in many industrial processes having many uses in the pharmaceutical, electronic, food and water purification industries. The present invention presents the use of sulfuric acid (H2SO4) as a catalyst utilizing water and electricity as the only raw materials for the production of H2O2. Separation processes are performed with membranes. Produced hydrogen is used as a fuel in a fuel cell, thereby reducing electrical cost.
