| New way to plug 'leaky' light cavities demonstrated Posted: 10 Dec 2014 11:08 AM PST Engineers have demonstrated a new and more efficient way to trap light, using a phenomenon called bound states in the continuum that was first proposed in the early days of quantum wave mechanics.  |
| New 'high-entropy' alloy is as light as aluminum, as strong as titanium alloys Posted: 10 Dec 2014 11:08 AM PST Researchers have developed a new 'high-entropy' metal alloy that has a higher strength-to-weight ratio than any other existing metal material.  |
| 'Smart windows' have potential to keep heat out and save energy Posted: 10 Dec 2014 09:14 AM PST Windows allow brilliant natural light to stream into homes and buildings. Along with light comes heat that, in warm weather, we often counter with energy-consuming air conditioning. Now scientists are developing a new kind of 'smart window' that can block out heat when the outside temperatures rise. The advance could one day help consumers better conserve energy on hot days and reduce electric bills.  |
| New 'electronic skin' for prosthetics, robotics detects pressure from different directions Posted: 10 Dec 2014 09:14 AM PST Touch can be a subtle sense, but it communicates quickly whether something in our hands is slipping, for example, so we can tighten our grip. For the first time, scientists report the development of a stretchable 'electronic skin' closely modeled after our own that can detect not just pressure, but also what direction it's coming from. The study on the advance could have applications for prosthetics and robotics.  |
| Defects are perfect in laser-induced graphene Posted: 10 Dec 2014 05:07 AM PST Researchers use lasers to create graphene foam from inexpensive polymers in ambient conditions. The laser-induced graphene may be suitable for electronics and energy storage.  |
| Scientists resolve spin puzzle Posted: 10 Dec 2014 05:06 AM PST Scientists have helped to uncover the properties of defects in the atomic structure of magnetite, potentially opening the way for its use in producing more powerful electronic devices.  |
