(Phys.org)—In a new study, scientists have proposed that tiny residual effects measured by ether-drift experiments in the 1920s and '30s may be the first evidence of a temperature gradient that was theorized in the 1970s, ...
(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) —The ability to make measurements of the biomolecular interactions that occur inside living cells is essential for understanding complex biological processes. But probing the inside of living cells without damaging ...
(Phys.org)—The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new ...
(PhysOrg.com) -- In an attempt to develop a power source that is compact, environmentally friendly, and has an unlimited lifetime, a team of researchers from Singapore has fabricated an energy harvesting device that generates ...
In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired ...
Ice-templating is a powerful technique to construct biological materials using ice nucleation and growth to obtain frozen material architectures, but scientists have been unable to control these two factors with effective ...
A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators - resulting in leak-free machines that can stay operating longer.
