Exploring chemical reactions using EUV The University of Tokyo has established a facility to study fast chemical reactions using a coherent extreme ultraviolet light source. The new coherent extreme ultraviolet (XUV) source facility enables researchers to explore time-dependent phenomena, such as ultrafast chemical reactions of biological or physical samples. Located in an underground fa... » read more
The Evolution Of High-Level Synthesis
By Brian Bailey - 27 Aug, 2020 - Comments: 3
High-level synthesis is getting yet another chance to shine, this time from new markets and new technology nodes. But it's still unclear how fully this technology will be used. Despite gains, it remains unlikely to replace the incumbent RTL design methodology for most of the chip, as originally expected. Seen as the foundational technology for the next generation of EDA companies around the ... » read more

Quantum Internet The U.S. Department of Energy (DOE) recently unveiled a strategy to develop a quantum Internet in the United States. DOE's 17 National Laboratories will serve as the backbone of the quantum Internet, which will rely on the laws of quantum mechanics to control and transmit information over a network. Currently in its initial stages of development, the quantum Internet coul... » read more

GaN-on-SOI power semis At the recent IEEE International Electron Devices Meeting (IEDM), Imec and KU Leuven presented a paper on a gallium-nitride (GaN) on silicon-on-insulator (SOI) technology for use in developing GaN power devices. With GaN-on-SOI technology, researchers have developed a 200-volt GaN power semiconductor device with an integrated driver and fast switching performance. ... » read more
Three-valued memory Scientists at the Tokyo Institute of Technology and the University of Tokyo developed a new three-valued memory device inspired by solid lithium-ion batteries which could potentially serve as low power consumption RAM. The new device consisted of a stack of three solid layers made of lithium, lithium phosphate, and gold. This stack is essentially a miniature low-capacity... » read more

Smartphone virus scanner Scientists at the University of Tokyo built a new type of virus scanner for smartphones: to detect diseases, not malware. The handheld, portable device uses a smartphone to help scan biological samples for influenza virus. The virus scanner is about the size of a brick, with a slot to position a smartphone such that its camera looks through a lens. Inside the device... » read more
