Abstract: Carbon-based electrodes such as for incorporation into ultracapacitors or other high power density energy storage devices, include activated carbon, carbon black, binder and at least one molecular sieve material. The molecular sieve component can adsorb and trap water, which can facilitate the use of the device at higher voltage, such as greater than 3V. The molecular sieve material may be incorporated into the carbon-based electrodes or formed as a layer over a carbon-based electrode surface.

Abstract: A lithium-ion capacitor may include a cathode, an anode, a separator disposed between the cathode and the anode, a lithium composite material, and an electrolyte solution. The cathode and anode may be non-porous. The lithium composite material comprises a core of lithium metal and a coating of a complex lithium salt that encapsulates the core. In use, the complex lithium salt may dissolve into and constitute a portion of the electrolyte solution.

Abstract: The present invention relates to imidazole, oxazole and thiazole derivatives of tumor-targeted drug combretastatin A4, and phosphate esters, sulfonate esters or pharmaceutically acceptable salts, glycoside derivatives, solvates thereof, wherein the A-ring comprises a 3,5-dimethoxyphenyl group having a substituent at the 4-position. The pharmacological activity assays have demonstrated that the compounds of the present invention have good in vitro anti-tumor activity and excellent tubulin inhibitory effect.

Abstract: A method for producing activated carbon includes heating a phenolic novolac resin carbon precursor at a carbonization temperature effective to form a carbon material, and reacting the carbon material with CO2 at an activation temperature effective to form the activated carbon. The resulting activated carbon can be incorporated into a carbon-based electrode of an EDLC. Such EDLC can exhibit a potential window and thus an attendant operating voltage of greater than 3V.

Abstract: Stabilized lithium particles include a lithium-containing core and a coating of a complex lithium salt that surrounds and encapsulates the core. The coating, which is a barrier to oxygen and water, enables the particles to be handled in the open air and incorporated directly into electrochemical devices. The coating material is compatible, for example, with electrolytic materials that are used in electrochemical cells. The average coated particle size is less than 500 microns.

Abstract: The method and apparatus for monitoring a photo-detector generates a highly compliant mirror current across a broad range of photo-detector current levels. The apparatus for monitoring includes: a pair of bipolar transistors and a first non-linear isolation element. The pair of transistors are connected in a mirror configuration with a sense transistor one of the pair of transistors sensing a photo-detector current and with a mirror transistor one of the pair of transistors mirroring the photo-detector current with a mirror current. The first non-linear isolation element has at least two terminals a first of which couples to the collector of the mirror transistor. The first non-linear isolation element exhibits a non-linear voltage drop between the at least two terminals in response to varying levels of the mirror current to improve compliance between the mirror current and the detector current. Methods and means for monitoring a photo-detector are also disclosed.
