Graphene oxide membranes could reduce paper industry energy costs
The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper m.....»»
The quest for the magic angle
Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal.....»»
As coronavirus variants spread, the US struggles to keep up
Without federal strategy or enough funding, US sequencing superpowers don't work. Enlarge (credit: Bing Guan | Bloomberg | Getty Images) Across the US, the coronavirus is in retreat. The pandemic is still raging, mind you, with more than 70,00.....»»
Researchers clarify the microscopic origin of dissipation with graphene
Mechanical sources of dissipation play a key role in modern physics, with applications that span nanomechanics, biomechanics, materials science, and quantum computing. In clocks and other vibrating mechanisms, energy loss is usually proportional to t.....»»
3-D-printing perovskites on graphene makes next-gen X-ray detectors
Since Wilhelm Röntgen discovered them in 1895, X-rays have become a staple of medical imaging. In fact, barely a month after Röntgen's famous paper was published, doctors in Connecticut took the first ever radiograph of a boy's broken wrist......»»
Capturing the contours of live cells with novel nanoimaging technique using graphene
With every passing day, human technology becomes more refined and we become slightly better equipped to look deeper into biological processes and molecular and cellular structures, thereby gaining greater understanding of mechanisms underlying diseas.....»»
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.....»»
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.....»»
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.....»»

"Magnetic graphene" forms a new kind of magnetism
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.....»»
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.....»»
Anna-Sophie Dienemann creates wearable pop-up "distance keepers"
Design Academy Eindhoven graduate Anna-Sophie Dienemann has developed a line of accessories to encourage social distancing that can be unleashed by the wearer when others come too close. Read more Design Academy Eindhoven graduate Anna-Sophi.....»»
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.....»»
