摘要： A wafer has a layer containing silicon, a layer of polycrystalline diamond deposited on the silicon-containing layer, and a bow-compensation layer on the other side of the silicon-containing layer for reducing wafer-bow. A method of making a bonded structure includes an activation process for creating dangling bonds on the surface of one substrate, followed by contact-bonding the surface to a second substrate at low temperature. A bonded structure may include two substrates contact bonded to each other, one substrate including a layer containing silicon, a layer of polycrystalline diamond, a bow-compensation layer for reducing wafer-bow of the first substrate, and the other substrate including gallium nitride, silicon carbide, lithium niobate, lithium tantalate, gallium arsenide, indium phosphide, or another suitable material other than diamond.

摘要： An immobilized chalcogen system or body includes an element of chalcogen, an electrically conductive material, and a hydrophilic membrane gate. The hydrophilic membrane gate may be used to isolate hydrophobic regions, one related to polychalcogenide ion(s) and another related to a hydrophobic electrolyte system. The hydrophilic membrane gate may prevent polychalcogenide from forming, and may provide control of undesirable parasitic mass transport and undesirable electron transport inside a chalcogen-based battery, and thereby allow the battery to cycle at a high specific capacity with a long cycling life. If desired, the immobilized chalcogen system or body may be employed in a cathode of a rechargeable battery.

摘要： A charging station including a “reservoir” energy supply is proposed. The reservoir supply is formed of one or more rapid charge/discharge batteries that are also able to hold their charge for an extended period of time (as compared to conventional supercapacitors, for example). The reservoir supply is contemplated to accommodate transient increases in power demand when a given charging station has to re-charge several vehicles (for example) at the same time. The rechargeable batteries forming the reservoir are advantageously configured to thereafter be re-charged at a fast rate as well, making them ideal candidates for re-charging from secondary sources (such as, but not limited to, solar, fuel cells, wind, and the like).
