Jan 31, 2025 (Nanowerk Spotlight) Inside the human digestive tract, an electronic capsule can now generate its own electricity using recycled seaweed, power small electronic devices, with the duration depending on the specific energy requirements of each device, kill harmful bacteria through electrical pulses, and then breaks down into fragments...
Light-twisting materials created from nano semiconductors
Jan 31, 2025 (Nanowerk News) Cornell scientists have developed a novel technique to transform symmetrical semiconductor particles into intricately twisted, spiral structures – or “chiral” materials – producing films with extraordinary light-bending properties. The discovery, detailed in a paper in the journal Science ("Transforming achiral semiconductors into chiral domains with...
3D-printed nanopillars promote neuron growth
Jan 30, 2025 (Nanowerk News) Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers of the University of Technology in Delft (TU Delft) have developed a 3D-printed ‘brain-like environment’ where neurons grow similarly to a real brain....
