Solar Storms Are Back, Threatening Life As We Know It On Earth by Brian K. Sullivan

Solar storms have their roots in an 11-year cycle that shifts the polarity of the sun’s magnetic field. The magnetic forces at work on the sun get tangled during the process, and can punch out through the surface, sending the sun’s plasma into outer space and potentially triggering storms on Earth. The most powerful geomagnetic […]

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% […]

Better Solutions For Making Hydrogen May Lie Just At The Surface by Christina Nunez, Argonne National Laboratory

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That’s because, even though hydrogen is abundant, it must be derived from another substance that contains it—and today, that substance is often methane gas. Scientists are seeking ways to isolate this energy-carrying element without using fossil […]

Explainer: The Toxic Water At Japan’s Fukushima Nuclear Plant

Japan will release about 1.25 million tonnes of Fukushima water into the sea – part of its plan to decommission the power station destroyed in the 2011 tsunami. Japan’s decision to release more than one million tonnes of treated radioactive water – equivalent to about 500 Olympic-sized swimming pools – from the tsunami-ravaged Fukushima nuclear […]

Low-Cost Solar-Powered Water Filter Removes Lead, Other Contaminants by Princeton University

A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid. The device resembles a large sponge that soaks up water but leaves contaminants-like lead, oil and pathogens-behind. To collect the purified water from the sponge, one simply places it in sunlight. The researchers […]

Reviewing Recent Advancements In The Development Of Solid-State Batteries by Ingrid Fadelli

Solid state batteries (SSBs) are an emerging battery technology with high energy densities that could compete with lithium-ion batteries (LIBs), which power a wide range of electronic devices on the market today. In contrast with classic LIBs, SSBs have a solid ‘ceramic’-based electrolyte that separates the anode and cathode inside the battery. In some batteries, […]

‘Wearable Microgrid’ Uses The Human Body To Sustainably Power Small Gadgets by University of California

Nanoengineers at the University of California San Diego have developed a “wearable microgrid” that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing. […]

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 […]
