Long-term solar energy storage Researchers from Chalmers University of Technology and Universidad de La Rioja created a system capable of storing solar energy for extended periods of time. The system, called Molecular Solar Thermal Energy Storage (MOST), hinges on a molecular photoswitch made from carbon, hydrogen and nitrogen. When the molecule is hit by sunlight, it turns into an energy-rich... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more

Atomristors for thin memory Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip. "For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more

Spintronics gains traction The field of spintronics is gaining interest. The technology could enable a new class of spin-based devices, which combine the switching speeds of logic and the non-volatility of memory. Controlling the magnetism by means of electric fields is the key for future devices, but the ability to switch ferromagnetism technology at room temperature is challenging. Helmho... » read more
