A team of scientists led by the U.S. Department of Energy's Ames Laboratory has developed a first-of-its-kind catalyst that is able to process polyolefin plastics, types of polymers widely used in things like plastic grocery bags, milk jugs, shampoo bottles, toys, and food containers.
An international joint research team including Dr Zi Yang MENG, Associate Professor of Department of Physics at the University of Hong Kong (HKU), has solved the puzzle of the NFL behaviour in interacting electrons systems, and provided a protocol for the establishment of new paradigms in quantum metals, through quantum many-body computation and analytical calculations. The findings have recently been published in Npj Quantum Materials.
Ultrathin materials such as graphene promise a revolution in nanoscience and technology. Researchers at Chalmers University of Technology, Sweden, have now made an important advance within the field. In a recent paper in Nature Communications they present a method for controlling the edges of two-dimensional materials using a 'magic' chemical.
A decades-old technique for probing protein motions proves more accurate than current practices.
Kamran Ullah from Pakistan and Hameed Ullah from Porto Alegre, Brazil have demonstrated the theory behind how a cavity optomechanical system induces OMIT and reduces the speed of light, in a paper in EPJ D entitled 'Enhanced optomechanically induced transparency and slow/fast light in a position-dependent mass optomechanics'
In the global race to measure ever shorter time spans, physicists from Goethe University Frankfurt have now taken the lead: together with colleagues at the accelerator facility DESY in Hamburg and the Fritz-Haber-Institute in Berlin, they have measured a process that lies within the realm of zeptoseconds for the first time: the propagation of light within a molecule. A zeptosecond is a trillionth of a billionth of a second (10 exp -21 seconds).
Magnesium silicide (Mg2Si) is a thermoelectric material that can convert heat into electricity. Though it is known that adding antimony impurities enhances the performance of Mg2Si, the mechanisms underlying this effect are unclear. Now, scientists from Japan shed light on the effects of these impurities at the atomic level, taking us closer to arriving at a practical way of efficiently harvesting waste heat from cars and thermal power plants to produce clean energy.
POSTECH Professors Daesu Lee and Si-Young Choi's joint research team demonstrates a novel physical phenomenon by controlling variations of the atomic structure.
Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a microchip technology that can convert invisible near-infrared laser light into any one of a panoply of visible laser colors, including red, orange, yellow and green. Their work provides a new approach to generating laser light on integrated microchips.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have proposed a novel method for finding dark matter, the cosmos' mystery material that has eluded detection for decades.
