Recycled Kevlar battery could boost electric car range by 5 times

A network of aramid nanofibers, recycled from Kevlar, can enable lithium-sulfur batteries to overcome their Achilles heel of cycle life—the number of times they...

This wearable air sampler could detect personal exposure to coronavirus

Masks, physical distancing, good hygiene, and ventilation can help reduce the transmission of COVID-19 in public places. But even when these measures are taken, scientists...

Scientists find way to boost perovskite solar cells with quantum dots

Perovskites are hybrid compounds made from metal halides and organic constituents. They show great potential in a range of applications, e.g. LED lights, lasers, and...

When graphene speaks, scientists can now listen

It may be true that seeing is believing, but sometimes hearing can be better. Case in point: Two brothers in a Rice University laboratory heard...

‘Fitbit for the face’ can turn any face mask into a smart monitoring device

In a new study from Northwestern University, researchers have developed a new smart sensor platform for face masks that they are calling a "Fitbit...

Graphene could replace rare metal used in smartphone screens, shows study

Scientists demonstrated the successful fabrication of an Organic Light-Emitting Diode (OLED) with a monolayer graphene anode, replacing ITO in organic light-emitting diodes. Indium is one...

Scientists develop stable sodium battery technology

Replacing lithium and cobalt in lithium-ion batteries would result in a more environmentally and socially conscious technology, scientists say. Toward that end, University of Texas...

Scientists revitalize batteries by bringing dead lithium back to life

Researchers may have found a way to revitalize rechargeable lithium batteries, potentially boosting the range of electric vehicles and battery life in next-gen electronic...

This coating could protect solar panels from snow and ice

Researchers have demonstrated an inexpensive, clear coating that reduced snow and ice accumulation on solar panels, enabling them to generate up to 85% more...

New atomically-thin material could improve efficiency of light-based tech

Solar panels, cameras, biosensors and fiber optics are technologies that rely on photodetectors, or sensors that convert light into electricity. Photodetectors are becoming more efficient...
