Salvaging Rare Earth Elements from Electronic Waste

Manufacturers rely on rare earth elements, like neodymium, to create strong magnets used in motors for electronics including hybrid cars, aircraft generators, loudspeakers, hard drives and in-ear headphones. But mineral deposits containing neodymium are hard to reach and are found in just a few places on Earth.

Monitoring Glucose Levels, No Needles Required

Noninvasive glucose monitoring devices are not currently commercially available in the United States, so people with diabetes must collect blood samples or use sensors embedded under the skin to measure their blood sugar levels. Now, with a new wearable device, less intrusive glucose monitoring could become the norm.

Wearable Head Scanner for Comfort, Mobility During Brain Scans

To collect accurate images of a patient's brain, the patient must be still and confined in a tube-like MRI scanner for a long period of time. To better assess their brain function and behavioral health, however, they should move naturally and freely during a scan. Researchers have proposed a solution to both clearly visualize and accurately assess the brain via photoacoustic imaging with a stretchable, flexible material.

Silicon Anodes Muscle in on Battery Technology

Silicon is a staple of the digital revolution, shunting loads of signals on a device that's likely just inches from your eyes at this very moment. Now, that same plentiful, cheap material is becoming a serious candidate for a big role in the burgeoning battery business. It's especially attractive because it's able to hold 10 times as much energy in an important part of a battery, the anode, than widely used graphite.

Inexpensive Tin Packs a Punch for Future Supercapacitors

A sustainable, powerful micro-supercapacitor may be on the horizon. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes — the connections responsible for managing the flow of electrons during charging and dispensing energy. Now, researchers have developed a better material to improve connectivity while maintaining recyclability and low cost.
