Disclosed is a single wall carbon nanotube (SWCNT) film electrode (FE), all-organic electroactive device systems fabricated with the SWNT-FE, and methods for making same. The SWCNT can be replaced by other types of nanotubes. The SWCNT film can be obtained by filtering SWCNT solution onto the surface of an anodized alumina membrane. A freestanding flexible SWCNT film can be collected by breaking up this brittle membrane. The conductivity of this SWCNT film can advantageously be higher than 280 S/cm. An electroactive polymer (EAP) actuator layered with the SWNT-FE shows a higher electric field-induced strain than an EAP layered with metal electrodes because the flexible SWNT-FE relieves the restraint of the displacement of the polymeric active layer as compared to the metal electrode. In addition, if thin enough, the SWNT-FE is transparent in the visible light range, thus making it suitable for use in actuators used in optical devices.

The present invention generally relates to high-energy composition utilized with reactors and combustors for generating electricity either directly through nuclear or magnetic energy, or indirectly through thermal energy that incorporate the high-energy composition into at least one reactor operable at a temperature greater than 1000 Celsius and containing the composition with at least one co-reactant of Boron-10, with the Boron-10 specifically enabling an at least five percent increase of energy generation and/or efficiency as compared the same reaction without Boron-10. In one embodiment, the present invention relates to the Boron-10 composition within a high-energy reactor operable at a temperature at least 1000 Celsius and a method that applies at least one externally applied force acting upon the Boron-10 portion of the reactor.

A process for producing borazane from boron-nitrogen and boron-nitrogen-hydrogen containing BNH-waste products. The process includes reacting the BNH-waste products with a hydrogen halide, having the formula HX, wherein X is selected from the group consisting of F, Cl, Br, I, and combinations thereof, to form any of the following: a boron trihalide, having the formula BX3, an ammonium halide, having the formula NH4X, and hydrogen. The boron trihalide is then reacted with the hydrogen to form diborane, having the formula B2H6, and hydrogen halide. The ammonium halide is then converted to ammonia, having the formula NH3, and hydrogen halide. The diborane is then reacted with the ammonia to form borazane, having the formula BH3NH3.

摘要:
A process is presented, with the help of which well-balanced mineral substance and trace element preparations with a very high biological value can be prepared. The core of the process is the combination of a special grinding process and a treatment of acids which conform to food. In particular, multi element solutions of nanocluster, as well as general supersaturated solutions of hardly to dissolve species can be prepared by use of the process, which have a high health use. The corresponding mineral substance concentrates are described and specified in detail in this paper as are the multi-component mineral substance preparations and solutions presented for the first time.
摘要:
A process for growth of boron-based nanostructures, such as nanotubes and nanowires, with a controlled diameter and with controlled chemical (such as composition, doping) as well as physical (such as electrical and superconducting) properties is described. The boron nanostructures are grown on a metal-substituted MCM-41 template with pores having a uniform pore diameter of less than approximately 4 nm, and can be doped with a Group Ia or Group IIa electron donor element during or after growth of the nanostructure. Preliminary data based on magnetic susceptibility measurements suggest that Mg-doped boron nanotubes have a superconducting transition temperature on the order of 100 K.
