Next-Generation Battery Technology

Sandia National Laboratory researchers have developed a family of liquid salt electrolytes - known as MetILs - that could lead to better batteries and well as devices that can help incorporate large-scale intermittent renewable energy sources, like solar and wind, into the nation’s electric grid.

Superconducting Current Limiter

A new superconducting current limiter based on YBCO strip conductors has been installed at a power plant. At the Boxberg power plant of the Swedish company Vattenfall, the current limiter protects the grid for own consumption that is designed for 12,000 volts and 800 amperes against damage due to short circuits and voltage peaks.

Lightweight, Solar-Powered Generator

An Office of Naval Research (ONR)-funded solar generator has recently entered full production, with several systems already in the field. The Ground Renewable Expeditionary ENergy System (GREENS) is a portable, 300-watt, hybrid battery generator that uses the sun to produce electric currents.

Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.

Low-Power Quantum Computers

By 2017, quantum physics will help reduce the energy consumption of computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next step will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as quantum tunneling. At the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, research is well underway.
