Graphene Nanoribbon Transistors Using Hydrocarbon Seeds (University of Wisconsin-Madison)


New research paper titled "Graphene nanoribbons initiated from molecularly derived seeds" from researchers at University of Wisconsin-Madison with contributions from Argonne National Laboratory. Abstract "Semiconducting graphene nanoribbons are promising materials for nanoelectronics but are held back by synthesis challenges. Here we report that molecular-scale carbon seeds can be exploi... » read more

Inside Intel’s Ambitious Roadmap


Ann Kelleher, senior vice president and general manager of Technology Development at Intel, sat down with Semiconductor Engineering to talk about the company’s new logic roadmap, as well as lithography, packaging, and process technology. What follows are excerpts of that discussion. SE: Intel recently disclosed its new logic roadmap. Beyond Intel 3, the company is working on Intel 20A. Wit... » read more

Machine-learning system determines the fewest, smallest doses that could still shrink brain tumors In an effort to improve the quality of life for patients by reducing toxic chemotherapy and radiotherapy dosing for glioblastoma, the most aggressive form of brain cancer, MIT researchers are employing novel machine-learning techniques. According to the team, glioblastoma is a malignant tumor ... » read more

Sensing without battery power Engineers at the National University of Singapore developed an IoT-focused sensor chip that can continue operating when its battery runs out of energy. The chip, BATLESS, uses a power management technique that allows it to self-start and continue to function under dim light without any battery assistance. The chip can operate in two different modes: minimum-ene... » read more

Carbon nanotubes “unzipped” into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free way to unzip them. A Rice materials scientist discovered that nanotubes that hit a target end first turn into mostly ragged clumps of atoms, but nanotubes that happen to broadside the target un... » read more

Better Beer Rice University has devised a polymer material that could boost the properties of natural gas, beer and soda. By adding modified, single-atom-thick graphene nanoribbons (GNRs) to thermoplastic polyurethane (TPU), Rice’s polymer material could make it more practical for vehicles to run on compressed natural gas. The material is far more impermeable to pressurized gas and lighte... » read more
