Set against a piece of black construction paper, the wings of the male cattleheart butterfly look even blacker than black.
"Some animals have taken black to an extreme," said Alex Davis, a graduate student in the lab of Duke University...
An atomically thin materials platform developed by Penn State researchers in conjunction with Lawrence Berkeley National Lab and Oak Ridge National Lab will open a wide range of new applications in biomolecular sensing, quantum phenomena, catalysis and nonlinear optics.
"We...
Graphene is 200 times stronger than steel and can be as much as six times lighter. These characteristics alone make it a popular material in manufacturing. Researchers at the University of Illinois at Urbana-Champaign recently uncovered more properties of...
Graphene is well-known for its remarkable electronic, mechanical and thermal properties, but industrial production of high-quality graphene is very challenging. A research team at Delft University of Technology (TU Delft, The Netherlands) has now developed a mathematical model that...
Leiden chemists have created a new ultrathin membrane only one molecule thick. The membrane can produce a hundred times more power from seawater than the best membranes used today. The researchers have published their findings in Nature Nanotechnology.
Thin and porous
When...
Today, most quantum experiments are carried out with the help of light, including those in nanomechanics, in which tiny objects are cooled with electromagnetic waves to such an extent that they reveal quantum properties. Now, a team of physicists...
It is a well-known school experiment: Applying a voltage between two electrodes inserted in water produces molecular hydrogen and oxygen. Researchers seek to make water splitting as energy-efficient as possible to advance industrial applications. The material of the electrode...
Researchers at the University of Bristol have come up with a new type of nanoelectromechanical relay to enable reliable high-temperature, non-volatile memory.
The work, which is reported in Nature Communications, was carried out in collaboration with the University of Southampton and...
Scientists have developed a three-dimensional imaging technique to observe complex behaviours in magnets, including fast-moving waves and 'tornadoes' thousands of times thinner than a human hair.
The team, from the Universities of Cambridge and Glasgow in the UK and ETH...
Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research of the Korea Institute of Science and Technology (KIST, President Lee Byung Gwon) have announced the development of silicon anode materials that can increase battery...
Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy,...
