Stress management in lithium-sulfur battery: some space to breathe

Lithium-ion batteries, of the type we can find in any house-hold, have changed the world. But as society moves away from fossil fuels, we will need cheaper and greener technologies for storing energy to support renewable electricity generation and electric vehicles. The Lithium-Sulfur (Li-S) battery... click to read more

A quantum step forward in high pressure science

Under normal conditions, some materials are naturally better at conducting electricity than others. By applying high enough pressure, some materials that normally block the flow of electricity, like sulfur, can become conductors better than copper or gold. A wire of such "superconductor" could theoretically deliver... click to read more

World’s first microscale ‘transformer’ robot

The live-action Transformers film series features Autobots, mechanical, modular robotic lifeforms that could change their bodies into various alternative modes such as weapons, vehicles or machinery, and help save our planet from alien threats. Inspired by this fantasy, scientists and engineers have been developing technologies... click to read more

Cooled to the Quantum Realm

Levitation of objects sounds like magic, but it is precisely what Arthur Ashkin's optical tweezer won the Nobel Prize for in 2018. An optical tweezer amounts to an intense laser that focuses down to a very small point. Optical tweezers trap an object put at... click to read more

A match made in heaven: Stacking two solar cells boosts their efficiency

The development and realization of clean, renewable energy is one of the significant problems of our time. Over 850 million people do not have access to electricity. We must find a way to deliver it while maintaining a sustainable climate and air pollution standards. Solar... click to read more
