Abstract: Compositions of matter including a cloth base comprising one or more not fully carbon fibers woven together, where at least a portion of the not fully carbon fibers of the cloth base are carbonized and comprise graphene petals thereon. The not fully carbon fibers may be selected from a variety of materials including cellulose fibers such as hemp, linen, and/or cotton, and may also or alternatively include synthetic fibers such as polyester, Kevlar, and/or Rayon. A method for producing such a carbonized conductive fiber-based cloth is also provided, the method including carbonizing a cloth base comprising not fully carbon fibers in a plasma stream of a plasma process and growing graphene petals integrally on the carbonized cloth using the same plasma process.

Abstract: A method of graphitic petal synthesis includes a step of providing a flexible carbon substrate, such as that including carbon microfibers. The method further includes the step of subjecting flexible carbon substrate to microwave plasma enhanced chemical vapor deposition. The resulting synthesized graphitic petal structure may optionally be coated with PANI.

Abstract: Pesudocapacitive electrodes having improved electrochemical properties for energy storage systems, and methods for their manufacture. The pseudocapacitive electrode may include a porous substrate and a nanoscale structure having an array of nanoneedles or an array of nanopetals located on the substrate. The nanoscale structure includes a bi- or tri-metal oxide or a bi- or tri-metal hydroxide.

Abstract: The present invention provides a data write-in method of flash memory for writing data into two or more flash chips, the method comprises: firstly correspond the physical blocks in the two flash chips to the odd logical block address and the even logical block address respectively; analyse the logical block address which corresponds to the write-in operation from the data write-in instruction; judge the parity of said logical block address and select the corresponding flash chip according to the result; operate the flash chip, detect whether or not the other flash chip needs to be programmed or erased after direct the instruction to program or erase the flash chip, when the other flash chip needs to be programmed or erased, then direct the program or erase instruction to the other flash chip. Using the method of the present invention can program and erase two flash chips simultaneously, thereby increasing the data write-in speed greatly.
