Tiny Electrical Vortexes Close Gap Between Ferroelectric and Ferromagnetic Materials

Material & Energy, Nanotechnology, Tech / Vicentina Inácio

Ferromagnetic materials possess a self-generating magnetic field; ferroelectric materials create their own electrical field. Electric and magnetic fields are important. Physics tells us that they are entirely different classes of material. Now the finding by University of Warwick-led scientists of a complex electrical ‘vortex-like’ pattern that mirrors its magnetic equivalent indicates that they could actually […]

AI-Driven Dynamic Face Mask Adapts To Exercise and Contamination Levels

Material & Energy, Nanotechnology / Ngoma Manuel

Many people have become familiar with using face masks to protect themselves and others throughout the coronavirus pandemic, yet that does not mean the masks are consistently comfortable, especially during exercise. Now, scientists reporting in ACS Nano have created a dynamic respirator that regulates its pore size in response to altering conditions, such as exercise
