Glycine, the simplest amino acid found in our bodies, has a superpower in its β-phase form: it is highly piezoelectric, meaning it can convert mechanical pressure into electricity. However, this phase of glycine is unstable, usually transforming into a non-piezoelectric α-phase before we can ever use it in a device. We wanted to see if we could trap this elusive phase in tiny spaces to keep it stable. https://phys.org/news/2026-05-stability-range-piezoelectric-glycine-nanoconfinement.html Nanophysics Wed, 13 May 2026 19:20:01 EDT news697886383 Professor Kyungwho Choi's team of the School of Mechanical Engineering at Sungkyunkwan University, in collaboration with Professor Jinsoo Kim's team in the Department of Chemical Engineering at Kyung Hee University, have proposed a strategy that simultaneously overcomes the limitations of conventional hydrogel-based triboelectric nanogenerators (TENGs)—namely low output performance, poor mechanical strength, and insufficient transparency—by utilizing biomimetic stevia. https://phys.org/news/2026-05-everyday-sweetener-powerful-transparent-stretchable.html Materials Science Mon, 11 May 2026 11:20:06 EDT news697713363 Your phone warms up after a 20-minute FaceTime call.
