Manufacturing Bits: March 21


Making harder windows Using cubic silicon nitride materials, a team of researchers have developed a harder window that can sustain severe conditions. There is a demand for harder and stronger windows in various applications, such as engines, ball bearings, cutting tools and other others. To enable this technology, researchers used materials based on transparent polycrystalline ceramics. One... » read more

TFETs Cut Sub-Threshold Swing


One of the main obstacles to continued transistor scaling is power consumption. As gate length decreases, the sub-threshold swing (SS) — the gate voltage required to change the drain current by one order of magnitude — increases. As Qin Zhang, Wei Zhao, and Alan Seabaugh of Notre Dame explained in 2006, SS faces a theoretical minimum of 60 mV/decade at room temperature in conventional MO... » read more

Higher-Than-Ballistic Conduction of Viscous Electron Flows (MIT & Weizmann)


Source: Massachusetts Institute of Technology, Weizmann Institute of Science, Rehovot  Israel Haoyu Guo, Ekin Ilseven, Gregory Falkovich, Leonid Levitov "A new finding by physicists at MIT and in Israel shows that under certain specialized conditions, electrons can speed through a narrow opening in a piece of metal more easily than traditional theory says is possible. This “superball... » read more

Math picture language Harvard University researchers reminded that Galileo called mathematics the “language with which God wrote the universe,” as he described a picture-language. Now that language has a new dimension. [caption id="attachment_35501" align="alignright" width="300"] Arthur Jaffe (left) and Zhengwei Liu are the creators of a new, 3D pictorial language for mathematics. They b... » read more

Power/Performance Bits: Feb. 28


Power converter for IoT At the International Solid-State Circuits Conference, researchers from MIT presented a new power converter that is efficient at a wide range of currents, which could be a boon for IoT sensors that have variable power requirements. The device maintains its efficiency at currents ranging from 500 picoamps to 1 milliamp, a span that encompasses a 200,000-fold increase in... » read more

Electronics for Venus A team of scientists at NASA's Glenn Research Center in Cleveland demonstrated the first prolonged operation of electronics in the harsh conditions found on Venus. Current Venus landers can only operate on the planet's surface for a few hours due to the extreme atmospheric conditions. The surface temperature on Venus is nearly 860 degrees Fahrenheit, and the planet h... » read more

Large scale quantum computer blueprint An international team comprised of researchers from the University of Sussex, Google, Aarhus University, RIKEN, and Siegen University recently unveiled what they say is the first practical blueprint for how to build a quantum computer. The team asserted that once built, the computer would have the potential to answer many questions in science; create n... » read more

Wearable AI System Can Detect A Conversation Tone (MIT)


Source: Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and Institute of Medical Engineering and Science (IMES); Tuka AlHanai and Mohammad Mahdi Ghassemi "It’s a fact of nature that a single conversation can be interpreted in very different ways. For people with anxiety or conditions such as Asperger’s, this can make social situations extremel... » read more

System Bits: Jan. 31


Optimizing code To address the issue of code explicitly written to take advantage of parallel computing usually losing the benefit of compilers’ optimization strategies, MIT Computer Science and Artificial Intelligence Laboratory researchers have devised a new variation on a popular open-source compiler that optimizes before adding the code necessary for parallel execution. Charles E. Lei... » read more

Modified carbon nanotubes used to track individual cells Carbon nanotubes come to the forefront of scientific research yet again, this time for serving as the most sensitive molecular sensing platforms available. MIT engineers believe they have designed sensors that, for the first time, can detect single protein molecules as they are secreted by cells or even a single cell. The sensors that... » read more
