Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad range of materials for use in things like sensors and detectors.

Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity. Their work has been published in the scientific journal Angewandte Chemie.
A major new study by an interdisciplinary team of researchers finds that it is possible -- and critical -- to bring industrial greenhouse gas emissions to net zero by 2070. Published Sunday in Applied Energy, the study assesses the range of technologies and policies interventions available to enable global industry decarbonization. This paper was the result of a collaboration among almost two dozen leading technical experts, led by Jeffrey Rissman of Energy Innovation and coauthored by Resources for the Future (RFF) Senior Fellow Dallas Burtraw.
At the BESSY II storage ring, a team has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. They used an elliptical double-undulator developed at HZB and operated the storage ring in the so-called two-orbit mode. This is a special mode of operation that was only recently developed at BESSY II and provides the basis for fast switching.
A team of scientists reports March 30 in the journal Proceedings of the National Academy of Sciences how carbon behaved during Earth's violent formative period. The findings can help scientists understand how much carbon likely exists in the planet's core and the ways it influences chemical and dynamic activities that shape the world, including the convective motion that powers the magnetic field that protects Earth from cosmic radiation.
Researchers at Linköping University, working with colleagues in Great Britain, China and the Czech Republic, have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. The result has been published in Nature Communications.
A research team at The University of Tokyo has introduced a machine-learning algorithm that can scan through microscope images to find 2D materials like graphene. This work can help shorten the time required for 2D material-based electronics to be ready for consumer devices.
Scientists studying high-Tc superconductors at the US Department of Energy's Brookhaven National Laboratory have definitive evidence for the existence of a state of matter known as a pair density wave -- first predicted by theorists some 50 years ago. Their results show that this phase coexists with superconductivity in a well-known bismuth-based copper-oxide superconductor.
Spanish conquerors depended on indigenous expertise to keep up their munitions supplies, archaeologists have found.
