Carbon-nanotube arrays take heat off chips
News & Analysis  
5/15/2006   Post a comment
A carbon-nanotube-based thermal material has been crafted by researchers at Purdue University to transfer heat away from the densely packed transistors that are increasingly being crammed onto silicon chips. The researchers claim that the material transfers heat away from chips to any heat sink faster than the liquid-cooled method used by many of today's manufacturers.

A virtual reality installation sporting 100 million pixels is being touted as offering the world's highest resolution, and could aid medical and military research.
Dip-pen technique drives molecular-scale litho
News & Analysis  
5/8/2006   Post a comment
IBM Corp. has found a way to electrically control the deposition rate of materials--the ink--from a dip-pen lithography system without lifting it from the substrate on which it is writing, thereby enabling molecular-scale nanolithography.
Screener promises better airport security
News & Analysis  
5/8/2006   Post a comment
U.S. airports have invested billions in security since the 9/11 terrorist attacks. Still, the Government Accountability Office managed to sneak bomb-making components onto planes at 21 U.S. airports--every one it tested--over a recent four-month period.
A Nobel effort
News & Analysis  
5/8/2006   Post a comment
Two scientists at IBM's Zurich Research Laboratory, Gerd Binnig and Heinrich Rohrer, won the 1986 Nobel Prize in physics for inventing the scanning tunneling microscope in the early 1980s. But that microscope needed an electrically conducting surface.

IBM uses atomic microscope for direct writing

IBM unveiled a new method of direct writing to substrates that harnesses an atomic force microscope to electronically control molecular-scale lithography.
Biofuel cell gets charge from the air
News & Analysis  
5/1/2006   Post a comment
Have you ever wondered why all the ingredients for fuel--hydrogen and oxygen--can't be harvested from air? Oxford University researchers wondered, too. In searching for the answer, the team discovered living enzymes that had already evolved to harvest hydrogen and oxygen from air. By fashioning a battery anode from a metal impregnated with that microbe, the researchers were able to demonstrate a biofuel cell with enough capacity to power a digital watch.
Nanogenerator takes charge from motion
News & Analysis  
5/1/2006   Post a comment
The first nanoscale piezoelectric generator, which could one day use environmental motion to provide unlimited electricity for small devices, has been demonstrated by researchers in Georgia.
