Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, ...
(Phys.org)—Scientists have demonstrated that pinwheel-shaped microgears floating on a liquid surface can rotate at speeds of up to 300 r.p.m. when illuminated by an ordinary LED. This light-driven motion, which arises because ...
(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
Tropical cyclones are extreme weather events, characterized by a circular form and formation over warm tropical oceans experiencing low atmospheric pressure, high winds and heavy rain. Tropical storms exceed 39 miles per ...
A study of 29 European lakes has found that some naturally-occurring lake bacteria grow faster and more efficiently on the remains of plastic bags than on natural matter like leaves and twigs.
