Upside-down design expands wide-spectrum super-camera abilities

By turning a traditional lab-based fabrication process upside down, researchers at Duke University have greatly expanded the abilities of light-manipulating metasurfaces while also making them much more robust against the ...

Tiny fish-shaped robot 'swims' around picking up microplastics

Microplastics are found nearly everywhere on Earth and can be harmful to animals if they're ingested. But it's hard to remove such tiny particles from the environment, especially once they settle into nooks and crannies at ...

All-optical switching on a nanometer scale

Ultrafast light-driven control of magnetization on the nanometer length scale is key to achieve competitive bit sizes in next generation data storage technology. Researchers at Max Born Institute in Berlin and of the large ...

Research team develops wood-based foam to keep buildings cooler

Summertime is almost here, a time when many people try to beat the heat. But running air conditioners constantly can be expensive and wasteful. Now, researchers reporting in the ACS journal Nano Letters have designed a lightweight ...

Spintronics: How an atom-thin insulator helps transport spins

An intermediate layer consisting of a few atoms is helping to improve the transport of spin currents from one material to another. Until now, this process involves significant losses. A team from Martin Luther University ...
