Flash memories have attracted considerable attention as promising next-generation nonvolatile memories owing to their higher chip density, multi-bit per cell storage property and compatibility with the current complementary metal–oxide–semiconductor (CMOS) process. Flash memories have been fabricate.....

During the turn-on and turn-off switching processes, power converters have to withstand high voltage and current, leading to high switching losses and stresses. The invention is a passive lossless snubber cell with minimum stress and wide soft-switching range. The energy reset / recirculation proces.....

The invention relates to an improved method for storing hydrogen in single-walled carbon nanotubes. Carbon nanotubes are dipped in hydrogen gas for absorption. The size of carbon nanotubes to be used depends on the density of hydrogen molecules, and generally, nanotubes of diameters from 0.5 to 1.2 .....
