Harmful Whiskers in Lithium Batteries

Authors: George Rajna

Scientists have uncovered a root cause of the growth of needle-like structures—known as dendrites and whiskers—that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire. [37] Scientists at the Okinawa Institute of Science and Technology Graduate University (OIST) report an approach for studying charge transfer that does not rely on complicated equipment—simplifying the real-time observation of catalysis. [36] Yi Zuo, University of Hawaii at Manoa College of Engineering and pediatrics professor, has invented a groundbreaking method that allows for easy determination of the surface free energy of particles as a quantitative measure of particle hydrophobicity. [35] A research team of Ehime University paved a way to achieve unexplored III-V semiconductor nanostructures. [34] Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. [33] Rice University scientists have found revealing information where light from a molecule meets light from a nanoparticle. [32] A University of Wyoming researcher and his team have shown, for the first time, the ability to globally align single-wall carbon nanotubes along a common axis. [31] The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics. [30] The solution consisting of colloidal quantum dots is inkjet-printed, creating active photosensitive layer of the photodetector. [29] I'm part of a group of nanotechnology and neuroscience researchers at the University of Washington investigating how quantum dots behave in the brain. [28] Nanotechnology may provide an effective treatment for Parkinson's disease, a team of researchers suggests. [27]
