Researchers have shown how to shuttle lithium ions back and forth into the crystal structure of a quantum material, representing a new avenue for research and potential applications in batteries, 'smart windows' and brain-inspired computers containing artificial synapses.

As researchers engineer solutions for eventually replacing electronics with photonics, a Purdue University-led team has simplified the manufacturing process that allows utilizing multiple colors at the same time on an electronic chip instead of a single color at a time.

Article describes PPPL research to help General Electric design an advanced and cost-effective power switch to protect the US electric grid.

A fabric coating with thin, lightweight and flexible pressure sensors that can be embedded into shoes and other functional garments, sensors that can measure everything from the light touch of a finger to being driven over by a forklift. And it's comfortable to boot!

An international team of scientists developed the world's first antilaser for nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists demonstrated that it is possible to absorb the selected signal completely, even though the nonlinear system makes it difficult to predict the waves behaviour. The results can be used to manipulate superfluid flows, create atomic lasers, and also study nonlinear optical systems. The study was published in Science Advances.

Engineers have developed printable metal tags that could be attached to plain objects, like water bottles, walls or doors, and turn them into 'smart' Internet of Things devices. The tags can also be fashioned into paper-thin control panels that can be used to remotely operate WiFi-connected speakers, smart lights and other smart home appliances. The metal tags are made from patterns of copper foil printed onto paper-like materials and disturb WiFi signals when touched.

Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. Now, physicists have revealed new behaviour involving the antiparticle equivalent of skyrmions in a ferromagnetic material. The researchers demonstrated their findings using advanced computer simulations that can accurately model magnetic properties of nanometre-thick materials. The results are published in Nature Electronics.

Computer simulations reveal new behavior of antiskyrmions in gradually increased electric currents.

Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a Rutgers University-New Brunswick-led study. The researchers' suspicious object detection system is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional screening typically requires high staffing levels and costly specialized equipment.
