Aug 24, 2024 (Nanowerk News) Scientists have harnessed elliptical micropillars to enhance the generation and detection of coherent acoustic phonons in the gigahertz range. This advancement represents a significant step forward in the development of more efficient nanoacoustic transducers. Controlling hypersound at the nanoscale has long been a significant challenge...
Superconductivity Is unpredictable at the edge
Aug 24, 2024 (Nanowerk News) Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must unwind. To accommodate this abrupt change, the electrons at the edge of the...
Using machine learning to speed up simulations of irregularly shaped particles
Aug 24, 2024 (Nanowerk News) Simulating particles is a relatively simple task when those particles are spherical. In the real world, however, most particles are not perfect spheres but take on irregular and varying shapes and sizes. Simulating these particles becomes a much more challenging and time-consuming task. The ability...
Turning bacteria into bioplastic factories
Aug 24, 2024 (Nanowerk News) In a world overrun by petroleum-based plastics, scientists are searching for alternatives that are more sustainable, more biodegradable and far less toxic to the environment. Two new studies by biologists at Washington University in St. Louis highlight one potential source of game-changing materials: purple bacteria...
