First Nanoscale Look At A Reaction That Limits The Efficiency Of Generating Clean Hydrogen Fuel by Glennda Chu

Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen. But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% […]

Researchers Improve Efficiency Of Next-Generation Solar Cell Material by David L. Chandler

Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives. Now, a new approach to […]

Researchers Create Entangled Photons 100 Times More Efficiently Than Previously Possible by Stevens Institute of Technology

Super-fast quantum computers and communication devices could revolutionize countless aspects of our lives—but first, researchers need a fast, efficient source of the entangled pairs of photons such systems use to transmit and manipulate information. Researchers at Stevens Institute of Technology have done just that, not only creating a chip-based photon source 100 times more efficient […]

The First Room-Temperature Superconductor Has Finally Been Found by Emily Conover

The compound conducts electricity without resistance up to 15° C, but only under high pressure. Dias and colleagues formed the superconductor by squeezing carbon, hydrogen and sulfur between the tips of two diamonds and hitting the material with laser light to induce chemical reactions. At a pressure about 2.6 million times that of Earth’s atmosphere, […]
