Researchers report switching material between semiconductor and metallic states
A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that a semiconductor can be converted to a metal and back by light more easily and more quickly than previously tho.....»»
Star employees get most of the credit—and blame
Working with a "star" employee—someone who demonstrates exceptional performance and enjoys broad visibility relative to industry peers—offers both risks and rewards, according to new research from the Cornell University's ILR School......»»
Kagome graphene promises exciting properties
Researchers around the world are searching for new synthetic materials with special properties like superconductivity—that is, the conduction of electric current without resistance. These new substances are an important step in the development of h.....»»
Finding the best targets to improve crop yield by following CO2 journey inside the leaf
A team of scientists have measured the relative importance of the different obstacles that carbon dioxide (CO2) encounters in its voyage from the atmosphere to the interior of plant cells, where it is converted into sugars. This research leading meth.....»»
Wafer-scale production of graphene-based photonic devices
Our world needs reliable telecommunications more than ever before. However, classic devices have limitations in terms of size and cost and, especially, power consumption—which is directly related to greenhouse emissions. Graphene could change this.....»»
Iridium-catalyzed Z-retentive asymmetric allylic substitution reactions
In synthetic organic chemistry, Z-olefins are a challenging synthetic target to produce in the lab due to their relative thermodynamic instability. The Z-olefins form an unsaturated compound with a CnH2n formula that can be readily isomerized. Analog.....»»
Smaller, more powerful devices possible with new technique
Shrinking semiconductors even further would enable a whole new silicon revolution. But because that's impossible, the next best hope is integrating semiconductors with 2-D atomically-thin materials, such as graphene, upon which circuits can be create.....»»
After COVID-19 hit, federal financial aid applications dropped sharply among first-year students
After the COVID-19 crisis hit last March, federal student aid applications among potential college freshmen in California dropped 14 percent between mid-March and mid-August, relative to prior years. While there were also initial declines in applicat.....»»

Researchers have identified a new form of magnetism in so-called magnetic graphene, which could point the way toward understanding superconductivity in this unusual type of material......»»
A magnetic twist to graphene
Electrons in materials have a property known as 'spin," which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the spins in their electrons a.....»»
Scientists use trilayer graphene to observe more robust superconductivity
In 2018, the physics world was set ablaze with the discovery that when an ultrathin layer of carbon, called graphene, is stacked and twisted to a "magic angle," that new double layered structure converts into a superconductor, allowing electricity to.....»»
Study locates origins of glacier soot pollution in Northern India
New research identifies the relative importance of different sources of pollutants that accelerate glacial melting in the Indian Western Himalayas. This work can contribute directly to strategies to reduce pollutants at the source. Though earlier wor.....»»
Quantum tunneling in graphene advances the age of terahertz wireless communications
Scientists from MIPT, Moscow Pedagogical State University and the University of Manchester have created a highly sensitive terahertz detector based on the effect of quantum-mechanical tunneling in graphene. The sensitivity of the device is already su.....»»
Physicists create tunable superconductivity in twisted graphene "nanosandwich"
When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy......»»
Observing chiral edge states in gapped nanomechanical graphene
Edge states are an emerging concept in physics and have been explored as an efficient strategy to manipulate electrons, photons and phonons for next-generation hybrid electro-optomechanical circuits. Scientists have used gapless chiral edge states in.....»»
Researchers develop new graphene nanochannel water filters
When sheets of two-dimensional nanomaterials like graphene are stacked on top of each other, tiny gaps form between the sheets that have a wide variety of potential uses. In research published in the journal Nature Communications, a team of Brown Uni.....»»
