Just squeeze in -- when spaces are tight, nature loosens its laws
It turns out that when they're in a hurry and space is limited, ions, like people, will find a way to cram in -- even if that means defying nature's norms. Recently published research from an international team of scientists, including Drexel University's Yury Gogotsi, PhD, shows that the charged particles will actually forgo their 'opposites attract' behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial.

New quantum phenomena in graphene superlattices
Graphene Flagship researchers show the first new type of quantum oscillation to be reported for thirty years. It is the first of its kind to be present at high temperature and on the mesoscale and sheds light on the Hofstadter butterfly phenomenon.

Scientists demonstrated 1.3 μm submilliamp threshold quantum dot micro-lasers on Si
A group of researchers from the Hong Kong University of Science and Technology and University of California, Santa Barbara, successfully demonstrated record-small electrically pumped micro-lasers epitaxially grown on industry standard (001) silicon substrates in a recent study. A submilliamp threshold of 0.6 mA, emitting at the near-infrared (1.3?m) was achieved for a micro-laser with a radius of 5 μm. The thresholds and footprints are orders of magnitude smaller than those previously reported lasers epitaxially grown on Si.

World first: 'Storing lightning inside thunder'
In a world first, University of Sydney researchers have stored photonic information on a microchip as an acoustic wave. This allows precious extra time to store, process and then redistribute the data without relying on electronics, which produce excess heat. Such a hybrid chip could have a huge impact in cloud computing and telecommunication centres, which are overheating as we churn through data on our phones.

Sensing with a twist: A new kind of optical nanosensor uses torque for signal processing
As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging to develop. An international group of researchers have put a literal twist on this challenge, demonstrating a new nanoscale optomechanical resonator that can detect torsional motion at near state-of-the-art sensitivity. Their resonator, into which they couple light, also demonstrates torsional frequency mixing, a novel ability to impact optical energies using mechanical motions.

Hydrogen power moves a step closer
Physicists are developing methods of creating renewable fuel from water using quantum technology. Renewable hydrogen can already be produced by photoelectrolysis where solar power is used to split water molecules into oxygen and hydrogen. But fundamental problems remain before this can be adopted commercially due to inefficiency. The study demonstrates that the novel use of nanostructures could increase the maximum photovoltage generated in a photoelectrochemical cell, increasing the productivity of splitting water molecules.

Nanotechnology experts at Sandia create first terahertz-speed polarization optical switch

Self-healing gold particles
Self-healing materials are able to repair autonomously defects, such as scratches, cracks or dents, and resume their original shape. For this purpose, they must be composed of several components whose combined properties result in the desired characteristics. Scientists of the Karlsruhe Institute of Technology (KIT) and the Technion - Israel Institute of Technology now discovered that also tiny particles of pure gold have surprising self-healing capacities.

Filtering molecules from the water or air with nanomembranes
Free-standing carbon membranes that are a millionth of a millimetre thin: these are a special research field of Professor Dr. Armin Gölzhäuser from Bielefeld University and his research group. The nanomembranes can serve as ultrafine filters and as a protective layer. The Bielefeld physicists have registered several patents for manufacturing such molecular foils.

Self-folding electronics could enable advanced robotics (video)
As demand grows for more versatile, advanced robotics and other technologies, the need for components that can enable these applications also increases. Producing such components en masse has been a major challenge. But now, in ACS Applied Materials & Interfaces, researchers report that they have developed a way to help meet this need by printing electronics that can fold themselves into a desired shape.

Quantum sensors decipher magnetic ordering in a new semiconducting material
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale.

As 'flesh-eating' Leishmania come closer, a vaccine against them does, too
Boils the size of sand dollars, facial damage reminiscent of acid wounds, death by maiming of the liver and spleen. Leishmania parasites inflict suffering around the world that is the stuff of parables. They are the second-deadliest parasites after malaria, and global warming is slowly pushing them north toward the United States. Can a new experimental vaccine someday stop them? The vaccine has worked in humanized mice, as detailed in a new study.
