A new spectroscopy method is bringing researchers closer to understanding - and artificially replicating - the solar water-splitting reaction at the heart of photosynthetic energy production. Understanding the step-by-step mechanism of photosynthesis could lead to methods of producing highly efficient solar energy.
Researchers have found that it is possible to make an electric circuit with a magnetic insulator. This was previously deemed impossible. The circuit is realized using spin waves: wave-like perturbations in the magnetic properties of a material.
Telecommunication networks will soon have to exploit the quantum properties of light. Researchers recently generated directly cross-polarized photon pairs on a chip, a first in quantum optics. Polarization will now be among the controllable parameters for harnessing light, helping the creation of low cost, high performance, energy efficient technologies.
A research team has discovered that a primitive form of the liquid-gas transition extends far into the supposedly featureless supercritical phase at the molecular scale in water and demonstrated that the conclusions are likely to apply more generally.
Researchers have built an atomic X-ray laser with the shortest wavelength yet, producing a stable beam with a wavelength of 1.5 Angstrom, or 0.15 nanometers. This tiny wavelength is nearly ten times shorter than that of previously-reported atomic lasers.
The list of potential mechanisms that underlie an unusual metal-insulator transition has been narrowed by a team of scientists using a combination of X-ray techniques. This transition has ramifications for material design for electronics and sensors.
An overview of regulatory solutions worldwide on the use of nanotechnology in food and feed production shows a differing approach: only the EU and Switzerland have nano-specific provisions incorporated in existing legislation, whereas other countries count on non-legally binding guidance and standards for industry.
