A team of researchers from Penn State have developed a new and unique technique that enables the detection of single molecules of biological and chemical species from solid, liquid and gaseous samples, based on the ultra sensitivity of the surface-enhanced Raman scattering (SERS) with a slippery surface invented by Penn State. The researchers believe that the new technology would pave the way for various applications in the field of analytical chemistry, molecular diagnostics, environmental monitoring and national security.
Rice University scientists have invented an adaptive material, self-adaptive composite (SAC), that combines reversible self-stiffening and self-healing properties. SAC comprises a solid matrix composed of sticky micron-scale rubber balls.
Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun’s energy and then releases it as a burst of heat to melt away a layer of ice.
What do astrophysics, telecommunications and pharmacology have in common? Each of these fields relies on polarimeters — instruments that detect the direction of the oscillation of electromagnetic waves, otherwise known as the polarization of light.
A team of researchers from the University of Edinburgh has reconstructed a unique material which constitutes much of the larger planets in the solar system.
A new alloy with cold-loving features is reported to be one of the toughest metallic alloys ever, according to a team of Berkeley Lab researchers.
A team of scientists from the Moscow Institute of Physics and Technology (MIPT) and the Landau Institute for Theoretical Physics in the Russian Academy of Sciences has proposed a two-dimensional metamaterial composed of silver elements, that refracts light in an unusual way.
A team of physicists from ITMO University, Ioffe Physical-Technical Institute and Australian National University have researched the phenomenon of phase transition between photonic crystals and metamaterials - two types of periodic structures capable of manipulating light in intricate ways. The study helps to gain an insight into the fundamental properties of periodic structures and opens new possibilities for the design and creation of new electromagnetic materials. The results of the study were published in Nature Communications.
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.
Star Wars VII: The Force Awakens hits movie screens this week with its intense plot, edge-of-your-seat action scenes and, of course, lots of lightsabers. But is it actually possible to create a real-life lightsaber or build a functioning Death Star laser? To answer these questions and more, Reactions explores the science behind the Star Wars franchise.
