A groundbreaking research effort involving scientists at NREL; Lawrence Berkeley National Laboratory (LBNL); University of Colorado, Boulder (CU); and other partner institutions around the country recently published 'A Map of the Inorganic Ternary Metal Nitrides,' which appears in Nature Materials.

In a paper presented at the recent IEEE Symposium on Security and Privacy, MIT researchers detail a system that, for the first time, automatically generates optimized cryptography code that's usually written by hand. Deployed in early 2018, the system is now being widely used by Google and other tech firms.

We investigated the history of Japanese black tea, its decline, the manufacturing technology and the components of tea. We found that the main reasons for the revival and spread of Japanese black tea were production and manufacturing innovation. Fermentation is an especially important process because it determines tea quality. Fermentation technology was established by entrepreneurial farmers and transferred to other Japanese black tea farmers, resulting in the rapid market creation of Japanese black tea.

Ferroelectric FET (FeFET) is a promising memory device because of its low-power, high-speed and high-capacity. Toward 3D integration for higher capacity, a team of researchers developed a ferroelectric-HfO2 based FeFET with 8nm-thick IGZO channel instead of poly-silicon channel. They achieved nearly ideal subthreshold swing of 60mV/dec and higher mobility than poly-silicon channel thanks to the material property of IGZO and junctionless transistor operation. The obtained results will contribute to ultralow power devices for IoT applications.

While stories in the media present automation as having the potential to eliminate large swaths of jobs in the near future, a new study by researchers Maury Gittleman and Kristen Monaco argues otherwise.

Inspired by snail biology, scientists at the University of Pennsylvania, Lehigh University and the Korea Institute of Science and Technology have created a super-glue-like material that is 'intrinsically reversible.' In other words, it can easily come unglued. They have reported their findings in a paper published today in Proceedings of the National Academy of Sciences.

Indium-gallium-zinc oxide ceramics are used as the backplane for flat-panel displays, this was made possible through substantial synergistic contributions coming from the powerhouse that is Japan. A team of researchers from Japan reports the synthesis of centimeter-scale single crystals of a particular type of these semiconductors, InGaZnO4 (IGZO-11), with attractive characteristics such as wide band gap and high electrical mobility and conductivity, which make it promising candidates for transparent optoelectronic devices like touchable displays and organic LEDs.
