Backscatter Wi-Fi radio Engineers at the University of California San Diego developed an ultra-low power Wi-Fi radio they say could enable portable IoT devices. Using 5,000 times less power than standard Wi-Fi radios, the device consumes 28 microwatts while transmitting data at a rate of 2 megabits per second over a range of up to 21 meters. "You can connect your phone, your smart devices, ... » read more

Six-angstrom waveguide Engineers at the University of California San Diego, City University of New York, and Johns Hopkins University created the thinnest optical waveguide yet. At only three atoms thick, the team says the waveguide serves as a proof of concept for scaling down optical devices. The waveguide consists of a tungsten disulfide monolayer (made up of one layer of tungsten atoms ... » read more

Spray-on antenna Engineers at Drexel University developed a sprayable form of the 2D material MXene that can be used to create antennas on nearly any surface. The antennas perform as well or better than the ones currently used in mobile devices and RFID tags. The MXene titanium carbide can be dissolved in water to create an ink or paint. The exceptional conductivity of the material enables ... » read more

Recycling cathodes Nanoengineers at the University of California San Diego developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. In new batteries built with the cathodes, charge storage capacity, charging time and ba... » read more
