Washington, November 21 : Devices like cell phones, digital cameras, and notebook computers may soon be available with longer running times, thanks to Korean researchers at Hanyang University who have developed a new material for anodes that are used in their batteries to absorb lithium ions.

Research leader Jaephil Cho has revealed that the new material involves three-dimensional silicon structures that are highly porous.

Lithium ion accumulator batteries produce current by moving lithium ions. They usually contain a cathode (positive electrode) made of a mixed metal oxide, such as lithium cobalt oxide, and an anode (negative electrode) made of graphite.

With the aim to strengthen the bond among them, AT&T and Samsung have taken a step ahead together and brought out a new phone, Samsung Eternity aka the Samsung SGH-a867.

London, October 29: Microsoft researchers have developed a system called SideSight that can allow a mobile phone user to control a handset placed on a table by wiggling his/her fingers in the space around it.

The technology was unveiled last week at the User Interface in Software and Technology symposium in Monterey, California.

Alex Butler, a researcher from the Sensors and Devices Group at Microsoft Research Cambridge in the UK, has revealed that the system derives its exceptional ability from infrared sensors that can pick up the movement of fingers up to 10 centimetres away.

"The big advantage of our prototype is the finger does not block any of the screen space," New Scientist magazine quoted Butler as saying.

Indian mobile users will now have a chance to own Nokia's N85 multimedia phone from the premium N series of Nokia.
