The comprehensive characterization of hydrogen at ultra-high pressures
Physicists and material scientists have been trying to metallize hydrogen for many decades, but they have not yet succeeded. In 1968, British physicist Neil Ashcroft predicted that atomic metallic hydrogen would be a high-temperature semiconductor......»»
New family of wheel-like metallic clusters exhibit unique properties
While the wheel does not need to be reinvented, there are benefits to the development of new nano-wheels, according to a multi-institute research team based in China. The group fabricated a novel family of metallic compounds, each of which exhibit un.....»»
Enset, Ethiopia"s remarkable "tree against hunger" flowers at Kew Gardens for the first time
Enset (Ensete ventricosum), an African relative of the much-beloved banana plant, is flowering inside of Kew Gardens' Temperate House, marking the very first time this extraordinary plant has produced an inflorescence at the botanic garden. Royal Bot.....»»
Migrating ions through the perovskite layer in two dimensions
Electrostatic doping has been widely used in low-dimensional materials, including carbon nanotube (CNT) and two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs). Unlike conventional lattice doping with impurity.....»»
Giant magnetoresistance of Dirac plasma in high-mobility graphene
In a paper published in Nature this week (April 13, 2023), researchers from The University of Manchester report record-high magnetoresistance that appears in graphene under ambient conditions......»»
Study: No association between diversification of US police departments and clearance rates of crimes against minorities
Along with high rates of crime relative to other developed nations, the United States' crime clearance rates—the rates at which crimes are solved—are alarmingly low. One way to raise crime clearance rates is to diversify police departments. A new.....»»
Hot electron electrochemistry with ultrafast laser pulses
Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting in metallic surface stru.....»»
Researchers synthesize graphene using intense light
DGIST Professor Yoonkyu Lee's research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode material.....»»
How to improve water permeability and rejection performance of RGO membranes? RGO-MXene membranes give answer
Membrane separation technology has become one of the most effective methods for water treatment, owing to its advantages of high separation efficiency, convenient operation and low-energy consumption. The membranes prepared from graphene oxide (GO) h.....»»
Why you should treat ChatGPT like any other vendor service
Although OpenAI is an established organization with many years of experience promoting and developing AI systems, the relative immaturity of the ChatGPT application, combined with the lack of security assurance available for OpenAI, can put organizat.....»»
New method gets better performance out of atomically thin transistors

New machine-learning approach identifies one molecule in a billion selectively, with graphene sensors
Graphene's 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its a.....»»
Jewel beetles evolve to see new colors by duplicating their genes
Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants......»»
Oxygen groups key to unlocking graphene"s antimicrobial potential, say scientists
The amount of surface oxygen in graphene materials is a key factor in how effective they could be in killing bacteria—a discovery which may help to design safer and more effective products to combat antimicrobial resistance......»»
