Ultracold atoms in the so-called optical lattices, which are generated by crosswise superposition of laser beams, have proven to be one of the most promising tools for simulating and understanding the behavior of many-body systems. However, the implementation in free space has some limitations such as the distance between the atoms (around 400 nm) and the short range of the interactions.
Traps. Whether you’re squaring off against the Empire or trying to wring electricity out of sunlight, they’re almost never a good thing. But sometimes you can turn that trap to your advantage. A team from the Univ. of Nebraska-Lincoln, working with researchers at NIST, has shown that electron-trapping defects that are typically problematic in solar cells can be an asset when engineering sensitive light detectors.
Microalgae offer a highly promising alternative to petroleum products without competing for resources used in the food industry. They have now been used, for the first time, to make asphalt. Researchers have recently proved the viability of bioasphalt, demonstrating its close similarity to the "real" asphalt used to pave roads.
Researchers at Oregon State Univ. have invented a new technology that can increase the bandwidth of Wi-Fi systems by 10 times, using LED lights to transmit information. The technology could be integrated with existing Wi-Fi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple Wi-Fi devices.
Dartmouth College astrophysicists and their colleagues haven’t only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe. Henize 2-10 is a small irregular galaxy that is not too far away in astronomical terms: 30 million light-years.
Fastening protein-based medical treatments to nanoparticles isn't easy. With arduous chemistry, scientists can do it. But like a doomed marriage, the fragile binding that holds them together often separates. This problem, which has limited how doctors can use proteins to treat serious disease, may soon change.
With a tag, an anchor and a cage that can be unlocked with light, chemists have devised a simple, modular system that can locate proteins at the membrane of a cell. The chemists fused proteins to molecules called SNAP-tags, modified enzymes that recognize a particular chemical group called a benzylguanine.
In a move that could improve the energy storage of everything from portable electronics to electric microgrids, Univ. of Wisconsin-Madison and Brookhaven National Laboratory researchers have developed a novel x-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.
A more effective method for closing gaps in atomically small wires has been developed by Univ. of Illinois researchers, further opening the doors to a new transistor technology. Silicon-based transistors have been the foundation of modern electronics for more than half a century. A new transistor technology, carbon nanotube wires, shows promise in replacing silicon because it can operate ten times as fast and is more flexible.
Massachusetts Institute of Technology physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas. As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the electrons, which can be used to map the electrons’ precise activity over several milliseconds.
Proximity effects in hybrid heterostructures, which contain distinct layers of different materials, allow one material species to reveal and/or control properties of a dissimilar species. Specifically, for a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition.
Sudden cardiac death accounts for approximately 10 percent of natural deaths, most of which are due to ventricular fibrillation. Each year it causes 300,000 deaths in the United States and 20,000 in Spain. Researchers have demonstrated for the first time that the transition to calcium alternans, an arrhythmia associated with increased risk of sudden death, has common features with the magnetic ordering of metals.
The editors of R&D Magazine have announced a deadline extension for the 2015 R&D 100 Awards entry process until May 18, 2015. The R&D 100 Awards have a 50 plus year history of awarding the 100 most technologically significant products of the year.
A new paper describes how an accurate statistical description of heterogeneous particulate materials, which is used within statistical micromechanics theories, governs the overall thermo-mechanical properties. This detailed statistical description was computed using a novel adaptive interpolation/integration scheme on the nation’s largest parallel supercomputers.
A research team has investigated the electronic properties of the family of unconventional superconductors based on fullerenes, which have the highest known superconducting critical temperature among molecular superconductors, and was able to demonstrate the guiding influence of the molecular electronic structure in controlling superconductivity and achieving maximum Tc.
