Tyndall National Institute create first junctionless transistor
Thursday, March 18th, 2010A team of scientists at the Tyndall National Institute in Cork, Ireland has created what they claim is the world’s first junctionless transistor.
The invention represents a breakthrough in transistors and nanoelectronics, and has the potential to revolutionize microchip manufacturing.
The approach uses a control gate around a silicon nanowire to control [...]
Generating hydrogen fuel from waste energy
Wednesday, March 17th, 2010We recently looked at a breakthrough in using sunlight to create hydrogen but now scientists have found a way to use ambient noise to turn water into usable hydrogen fuel. The process harvests small amounts of otherwise-wasted energy such as noise or stray vibrations from the environment to break the chemical [...]
Laser-activated nanotube speakers could be invisibly embedded in windows and walls
Monday, March 15th, 2010It is known that intense sound can be produced by electrically-powered nanotubes stretched into sheets, but researchers from University of Texas at Dallas (UT Dallas) have furthered this principle by arranging sheets of carbon nanotubes into “forests” which produce high-quality sound when struck with lasers. This is an exciting advancement [...]
Carbon nanotubes offer new way to produce electricity
Wednesday, March 10th, 2010Scientists have discovered that a moving pulse of heat traveling along the miniscule wires known as carbon nanotubes can cause powerful waves of energy.
These “thermopower waves” can drive electrons along like a collection of flotsam propelled along the surface of ocean waves, creating an electrical current. The previously unknown phenomenon [...]

A new nanotech catalyst
developed by McGill University Chemists Chao-Jun Li, Audrey Moores and their colleagues offers industry an opportunity to reduce the use of expensive and toxic heavy metals.
Catalysts are substances used to facilitate and drive chemical reactions. Although chemists have long been aware of the ecological and economic [...]
