Detecting Small Metallic Contaminants in Food Via Magnetization

July 29, 2015 — Researchers have developed a practical metallic-contaminant detector using three high-Tc RF superconducting quantum interference devices for food inspection. While the detection of small metallic ... read more

Cages Offer New Direction in Sustainable Catalyst Design

July 23, 2015 — Engineers have developed a new approach to structuring the catalysts used in essential reactions in the chemical and energy fields. The advance offers a pathway for industries to wean themselves off ... read more

July 23, 2015 — By encoding information in photons via their spin, 'photonic' computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information ... read more

New Finding Could Lead to Cheap, Efficient Metal-Based Solar Cells

July 23, 2015 — Although the domestic solar-energy industry grew by 34 percent in 2014, fundamental technical breakthroughs are needed if the U.S. is to meet its national goal of reducing the cost of solar ... read more

July 22, 2015 — For the first time, researchers have combined a novel synthesis process with commercial electron-beam lithography techniques to produce arrays of semiconductor junctions in arbitrary patterns within ... read more

July 21, 2015 — BPA's popularity soared after the 1950s, but evidence suggests that even low doses might be harmful to human and environmental health. Many manufacturers are now phasing out BPA, but it ... read more

July 20, 2015 — In a tremendous boost for spintronic technologies, scientists have shown that electrons can jump through spins much faster than previously ... read more

July 20, 2015 — Scientists studying thin layers of phosphorus have found surprising properties that could open the door to ultrathin and ultralight solar cells and LEDs. The team used sticky tape to create ... read more

July 17, 2015 — Research shows lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding ... read more

Drug-Encapsulating Nanoparticle With Bright Bio-Labels Measures How Anticancer Chemotherapy Formulations Enter Cells

July 16, 2015 — Part of a 1929 prediction by physicist Hermann Weyl -- of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point" -- has finally been ... read more

July 16, 2015 — Scientists have discovered Weyl fermions, elusive massless particles theorized 85 years ago that could give rise to faster and more efficient electronics because of their unusual ability to behave as ... read more

July 16, 2015 — Hexagonal boron nitride bends electromagnetic energy in unusual and potentially useful ways. Physicists recently found that nanoscale granules of the material can store light. Now they have shown ... read more

July 15, 2015 — Engineers have combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team designed a way to embed strongly luminescent nanoparticles ... read more

July 15, 2015 — The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this ... read more

July 14, 2015 — For the first time, the wavelike behavior of a room-temperature polariton condensate has been demonstrated in the laboratory on a macroscopic length scale. This represents a significant development ... read more

July 14, 2015 — How can two metals that are not magnetic combine to make a magnet? Scientists have found one answer in their creation of the first known itinerant antiferromagnet from nonmagnetic ... read more

July 14, 2015 — When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even ... read more

July 14, 2015 — Today, the LHCb experiment at CERN's Large Hadron Collider has reported the discovery of a class of particles known as ... read more
