Saws made of carbon

More material could be saved when manufacturing wafers in future. Ultra-thin saws made of carbon nanotubes and diamond would be able to cut through silicon wafers with minimum kerf loss. A new method makes it possible to ...

Exotic alloys for potential energy applications

The search for thermoelectrics, exotic materials that convert heat directly into electricity, has received a boost from researchers at the California Institute of Technology and the University of Tokyo, who have found the ...

Naturally occurring mineral for thermoelectric power generation

Researchers with the National Institute of Advanced Industrial Science and Technology have confirmed that a naturally occurring mineral, tetrahedrite, which mainly consists of non-toxic and earth-abundant elements, copper ...

Innovative self-cooling, thermoelectric system developed

Spanish researchers at the UPNA/NUP-Public University of Navarre have produced a prototype of a self-cooling thermoelectric device that achieves "free" cooling of over 30ºC in devices that give off heat. It is a piece of ...

Harvesting unused energy with flat thermoelectrics

A large proportion of the energy we produce disappears unused into thin air via waste heat. Tiny thermoelectric generators can tap this potential, whereby the electricity is produced by way of temperature differences. However, ...

US to restart plutonium production for deep space exploration

The end of NASA's plutonium shortage may be in sight. On Monday March 18th, NASA's planetary science division head Jim Green announced that production of Plutonium-238 (Pu-238) by the United States Department of Energy (DOE) ...

Fujifilm breaks record with thermoelectric material

(Phys.org)—Photographic film maker Fujifilm has been busy this year at the Nanotech 2013 conference being held in Tokyo. First came news of bendable/roll up speakers. Now the company is showing off a new thermoelectric ...

Improved thermoelectric materials with atomic layer deposition

Researchers at the Aalto University School of Chemical Technology have applied atomic layer deposition (ALD) technique to the synthesis of thermoelectric materials. Converting waste energy into electricity, these materials ...

Qatar unveils low-emission hybrid car

A Qatari research centre unveiled a low-emission and low-fuel-consumption hybrid car Wednesday on the sidelines of the UN climate talks taking place in the gas-rich country, it said in a statement.

Team demonstrates new hybrid nanomaterial for power generation

A University of Texas at Arlington physics professor has helped create a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current, surpassing earlier methods that used either light ...
