A solar cell you can bend and soak in water
Mar 27, 2024 (Nanowerk News) Researchers from the RIKEN Center for Emergent Matter Science and collaborators have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed. One of...
Biocompatible nanoparticles enhance systemic delivery of cancer immunotherapy
Mar 27, 2024 (Nanowerk News) Purdue University researchers are developing and validating patent-pending poly (lactic-co-glycolic acid), or PLGA, nanoparticles modified with adenosine triphosphate, or ATP, to enhance immunotherapy effects against malignant tumors. The nanoparticles slowly release drugs that induce immunogenic cell death, or ICD, in tumors. ICD generates tumor antigens...
Spiral magnetic fields surround black hole Sagittarius A*
Mar 27, 2024 (Nanowerk News) A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking...
