A promising new process, known as Atomic Layer Deposition, could potentially improve existing solar energy systems. The new technique has been invented by Brian Willis, an associate professor of chemical and biomolecular engineering at the University of Connecticut and the former director of UConn’s Chemical Engineering Program. He explored the so called rectennas, or nano-antennas, […]

Researchers at Aalto University School of Chemical Technology developed a new cost-effective method to convert waste energy into electricity without carbon dioxide emissions. The team defined the synthesis method as extremely suitable for growing films made of thermoelectric zinc oxide material. To improve the thermoelectric properties of the material, the team added small amounts of either aluminium or […]

By growing layers of zinc oxide and titanium dioxide on a semiconductor surface, researchers from the ÃƒÆ’Ã¢â‚¬Â°cole polytechnique fÃƒÆ’©dÃƒÆ’©rale de Lausanne (EPFL) have managed to create solar cells that can ultimately extract hydrogen from water under the direct action of sunlight, just like leaves do their natural photosynthesis.

Yet another chapter is about to be written in the history of lithium ion batteries. Present in almost any device from earpieces to electric cars, there is a need to use them in micro- or nano-sized devices. A DARPA-funded project aims at creating the smallest lithium ion batteries ever, as small as a grain of sand.
