Bioengineers and cognitive scientists have developed the first portable, 64-channel wearable brain activity monitoring system that’s comparable to state-of-the-art equipment found in research laboratories. The system is a better fit for real-world applications because it is equipped with dry EEG sensors that are easier to apply than wet sensors, while still providing high-density brain activity data.

Scientists at three Department of Energy national laboratories have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from damage.

Thousands bound together are still thinner than a single strand of human hair, but with research from Binghamton University, boron nitride nanotubes may help build better fighter planes and space shuttles. A team of scientists led by Changhong Ke, associate professor of mechanical engineering at Binghamton University’s Thomas J. Watson School of Engineering and Applied Science, and researcher Xiaoming Chen were the first to determine the interface strength between boron nitride nanotubes (BNNTs) and epoxy and other polymers.
