Power/Performance Bits: Oct. 6


Waste plastic supercapacitor Researchers from the University of California Riverside found a way to recycle waste plastic into energy storage devices. The work focused on polyethylene terephthalate plastic waste, or PET, which is found in soda bottles and many other consumer products. The researchers first dissolved pieces of PET plastic bottles in a solvent. Using electrospinning, they fab... » read more

Durian supercapacitors Researchers from the University of Sydney developed a method that uses durian and jackfruit waste to create supercapacitors. Supercapacitors are capable of quickly storing and discharging energy. The team says their fruit-based material is more efficient than ones typically made from activated carbon. "Using durian and jackfruit purchased from a market, we conver... » read more

High mobility transistor Engineers at the University of Delaware created a high-electron mobility transistor, a device that amplifies and controls electrical current, using gallium nitride (GaN) with indium aluminum-nitride as the barrier on a silicon substrate. Among devices of its type, the team says their transistor has record-setting properties, including record low gate leakage current... » read more

Textiles for energy storage Scientists at RMIT University developed a way to laser print waterproof textiles with graphene supercapacitors for embedded energy storage. The process takes three minutes to create a 10x10cm patch. The electronic textile is based on nylon coated with PDMS on one side for waterproofing. The other side was paint coated with graphene oxide and a binder to form thin... » read more

Scaling Battery Technology


Batteries are an essential ingredient for the growth of electronics from small devices used for IoT as well as large batteries for electric cars. Historically, battery energy density improves 5%-8% per year. While this is much slower than the historical improvements from Moore’s Law, it’s still the kind of growth that can result in leaps in efficiency, opening the door for a better experien... » read more

More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

Printed supercapacitors Researchers at Drexel University and Trinity College created ink for an inkjet printer from MXene, a highly conductive two-dimensional material, which could be used to print flexible energy storage components, such as supercapacitors, in any size or shape. The material shows promise as an ink thanks to its high conductivity and ability to apply easily to surfaces usi... » read more

Bio-hybrid fungi Researchers at Stevens Institute of Technology combined a white button mushroom, electricity-producing cyanobacteria, and graphene nanoribbons into a power-generating symbiotic system. "In this case, our system - this bionic mushroom - produces electricity," said Manu Mannoor, an assistant professor of mechanical engineering at Stevens. "By integrating cyanobacteria that ca... » read more

Physical neural network Engineers at UCLA built a physical artificial neural network capable of identifying objects as light passes through a series of 3D printed polymer layers. Called a "diffractive deep neural network," it uses the light bouncing from the object itself to identify that object, a process that consumes no energy and is faster than traditional computer-based methods of imag... » read more

Long-lived data storage Scientists from RMIT University and Wuhan Institute of Technology demonstrated a next-generation optical disk with up to 10TB capacity and a six-century lifespan using gold nanoparticles. The technology could radically improve the energy efficiency of data centers according to the researchers, using 1000 times less power than a hard disk center by requiring far less ... » read more
