UCLA researchers claim to have harnessed excess energy generated by a continuous-wave laser using a photovoltaic effect that converted heat into electricity to power a chip.
Defects spur light emission in nanotube FETs
News & Analysis  
6/26/2006   Post a comment
Portland, Ore. -- IBM Corp. researchers say they have characterized four types of carbon nanotube field-effect transistsor defects that can stimulate nanotube FETs to emit light.

Molecular switch promises to solve sticky situations
News & Analysis  
6/21/2006   Post a comment
Researchers have grafted organic light-switchable molecules onto a polymer so it can be switched from slippery to sticky with UV light. The technique could improve microfluidic chips used in medical applications.
Record-low gate voltage for nanotube field emitters
News & Analysis  
6/19/2006   Post a comment
Portland, Ore. -- Scientists at the U.S. Naval Research Laboratory in Arlington, Va., said they have fabricated arrays of high-current carbon nanotube field emitters with a record-low gate voltage of just 60 volts for emissions of up to 1.2 amps per square centimeter.

Technique takes flight to quickly erase hard drives
News & Analysis

Since the forced landing of a U.S. spy plane in China, researchers have been looking for a way to quickly erase computer hard drives to deny access to sensitive intelligence data.
Indium oxide may best GaAs for spintronics
News & Analysis  
6/12/2006   Post a comment
Portland, Ore. -- Harnessing electron spin for optomagneto-electronic devices will depend on materials that, like silicon, can separately adjust their densities and dopant levels to designer specifications. Indium oxide doped with chromium may fill the bill, according to a research team from the Massachusetts Institute of Technology and Boise State University.

Nanoscale jigs seen for MEMS
News & Analysis  
6/12/2006   Post a comment
Portland, Ore. -- Carbon nanotubes are the strongest material on earth, more stable and rigid than diamond. But once that strength is fractured, nanotubes can be collapsed into sheets of diamond. The force that is released is enough to extrude even the strongest metals. By virtue of the controlled collapsing of metal-filled nanotubes, researchers at Rensselaer Polytechnic Institute (Troy, N.Y.) hope to harness the power of diamonds to machine nanoscale pins and posts for microelectromechanical
Decoupling capacitors return to simpler times
Product News  
6/5/2006   Post a comment
AVX Corp. has made what it claims is a revolutionary step backward with its invention of a patented new land-grid array (LGA) architecture for decoupling capacitors.

Team posits 'cloaking' nanomaterial
News & Analysis  
6/5/2006   Post a comment
The researcher who introduced the concept of negative-index-of-refraction metamaterials in 2000 is now positing that materials with a variable refractive index could enable such fantastic applications as a Harry Potteresque "invisibility cloak."
