New research from Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, shows that wounds on cultured skin cells heal three times faster when stimulated with electric current. The project was recently granted more funding so the research can get one step closer to the market and the benefit of patients. Credit: ScienceContinue reading “Electrical Wound Care…”

The new self-powered thermoelectric generator device uses an ultra-broadband solar absorber (UBSA) to capture sunlight, which heats the generator. Simultaneously, another component called a planar radiative cooling emitter (RCE) cools part of the device by releasing heat. Credit: Haoyuan Cai, Jimei University.

Graphical abstract. Credit: Nanomaterials (2023). DOI: 10.3390/nano13081404 Topics: Biology, Environment, Nanomaterials, Nanotechnology Among the biggest environmental problems of our time, micro- and nanoplastic particles (MNPs) can enter the body in various ways, including through food. And now, for the first time, research conducted at MedUni Vienna has shown how these minute particles manage to breach the blood-brainContinue reading “Mice, Men, and Nanoparticles…”
