Electronic devices such as transistors are getting smaller and will soon hit the limits of conventional performance based on electrical currents. Devices based on magnonic currents -- quasi-particles associated with waves of magnetization, or spin waves, in certain magnetic...
Engineers at MIT and Penn State University have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes. In a paper published today in...
Rutgers and other physicists have discovered an exotic form of electrons that spin like planets and could lead to advances in lighting, solar cells, lasers and electronic displays. It's called a "chiral surface exciton," and it consists of particles...
Just as controlled-release medications slowly dole out their cargo after they experience a pH change in the body, implanted "artificial muscles" could someday flex and relax in response to light illuminating the skin. In pilot studies, scientists have...
Scientists from the University of California, Los Angeles (UCLA) and Solargiga Energy in China have discovered that caffeine can help make a promising alternative to traditional solar cells more efficient at converting light to electricity. Their research, published...
A team of international scientists from BAS, University of Iowa and GFZ German Research Centre for Geosciences has discovered a new method to explain how radiation belts are formed around the planet Saturn. Around Saturn, and other planets including...
Birds, fish and bacteria often gather into groups or swarms. This so-called collective behaviour requires all group members to continuously and reciprocally adapt their movements. It can be a challenging task, however, for researchers to ascertain the specific...
Researchers at Binghamton University, State University of New York, have developed skin-inspired electronics to conform to the skin, allowing for long-term, high-performance, real-time wound monitoring in users. "We eventually hope that these sensors and engineering accomplishments can help advance...
Hold a cold drink on a hot day, and watch as small droplets form on the glass, eventually coalescing into a layer of moisture (and prompting you to reach for a coaster). This basic physical process, condensation, is what...
In order to design noiseless electromagnetic (EM) devices, it is necessary to clarify the mechanism behind EM noise and theoretical calculations and computer simulations are performed for prediction assessment of devices. Two researchers at Osaka University developed an...
