New Roof Coating Keeps Roofs Much Cooler

Written by , on June 10, 2015

Scientists at the University of Technology Sydney have developed a coating which keeps roofs significantly cooler than the ambient air temperature, even under the most intense summer conditions. Dr Angus Gentle and Emeritus Professor Geoff Smith reported that a roof with a “coated polymer stack” – a combination of specially chosen polyesters on a silver […]  Read more »

Hybrid Supercapacitors Promise Large Storage and Fast Charging

Written by , on April 20, 2015

Scientists at UCLA have developed hybrid supercapacitors that can store as much charge as a lead acid battery, yet can be recharged in seconds compared with hours for conventional batteries.  Read more »

Solar Power at Night?

Written by , on March 11, 2014

Physicists at the Harvard School of Engineering and Applied Sciences, led by Federico Capasso, a world-renowned expert in semiconductor physics, photonics and solid-state electronics, have proposed a device that would harvest energy from Earth's infrared emissions into outer space. The device would consist of a "hot" plate at the temperature of the Earth and air, […]  Read more »

Using Viruses to Make Better Batteries

Written by , on March 10, 2014

Lithium-air batteries hold the promise of drastically increasing power per battery weight. However, achieving this requires solving a number of challenges, including the need to develop better, more durable materials for the batteries' electrodes and improving the number of charging-discharging cycles the batteries can withstand. MIT researchers believe that a combination of genetic engineering and […]  Read more »

Recycling Carbon Dioxide Using Gold Nanoparticles

Written by , on March 10, 2014

By using gold nanoparticles of just the right size, researchers from Brown University in Rhode Island have developed a catalyst that selectively converts carbon dioxide to carbon monoxide which can be used to make alternative fuels and useful chemicals. The scientists already knew that cabon dioxide can be converted into carbon monoixde by the presence […]  Read more »
