Printing RF antennas with graphene ink Researchers from the University of Manchester, together with BGT Materials Limited, a graphene manufacturer in the United Kingdom, printed a radio frequency antenna using compressed graphene ink. The antenna performed well enough to make it practical for use in RFID tags and wireless sensors, the researchers said. Even better, the antenna is flexible, e... » read more

Elastic energy harvesting Researchers from the Korea Advanced Institute of Science and Technology (KAIST) and Seoul National University collaborated to develop a hyper-stretchable elastic-composite energy harvesting device. Their stretchable piezoelectric generator can harvest mechanical energy to produce a ~4V power output with around 250% elasticity and a durability over 104 cycles. The... » read more

Towards spin-based computing It’s a given that semiconductors process electrical information, while magnetic materials enable long-term data storage. Along these lines, researchers from the University of Pittsburgh and the University of Wisconsin-Madison have discovered a way to fuse these two distinct properties in a single material that they believe could pave the way for new ultrahigh den... » read more

“Lock-free” vs. “wait-free” parallel algorithms Since computer chips have stopped getting faster, regular performance improvements are now the result of chipmakers’ adding more cores to their chips, rather than increasing their clock speed. And in theory, doubling the number of cores doubles the chip’s efficiency, but splitting up computations so that they run efficiently in parall... » read more
