Logic and memory shown on molecular scale
News & Analysis  
10/31/2003   Post a comment
Integrated circuits all depend on lockstep, unerring, nanoscale accuracy in their fabrication. Now Rice University researchers have challenged that wisdom by demonstrating that molecule-sized electronic devices can be used for both logic and memory, despite being randomly wired, error-prone and inaccurately formed at the nanoscale.
Nanosprings breakthrough shrinks size of sensors
News & Analysis  
10/30/2003   Post a comment
Quantum dots, nanowires and other nanoscale structures populate the frontier of semiconductor research, collectively aimed at downsizing chip components to the molecular scale.
Hybrid tunnel diodes could leapfrog Moore's Law
News & Analysis  
10/29/2003   Post a comment
Semiconductor researchers have known since the 1950s that the quantum-confinement effects of tunnel diodes boost circuit speed and current handling. Now some researchers say a new CMOS-compatible tunnel diode process could extend the lifetime of existing silicon fabs by leapfrogging the next node in the semiconductor road map.

Semiconductor researchers have known since the 1950s that the quantum-confinement effects of tunnel diodes boost circuit speed and current handling while reducing component count and power consumption.
Microfluidic battery runs on water
News & Analysis  
10/23/2003   Post a comment
Converting hydrostatic pressure directly into electrical current — without "moving parts" like a fuel cell — has enabled the demonstration of a new kind of battery. The electrokinetic microchannel battery prototype harnessed the combined sub-nanoamp electrical output from 500,000 microfluidic channels to generate microamps of power.
Silicon IC unravels DNA's spiral for easy reading
News & Analysis  
10/22/2003   Post a comment
Researchers at Purdue University have succeeded in unraveling strands of DNA into an easy-to-ready linear "tape," potentially a first step toward one day creating computers based on DNA, according to the team.
EEG brain cap detects musical creativity

Analog CMOS chip mimics octopus retina
News & Analysis  
10/7/2003   Post a comment
Neophyte scuba divers tend to expect underwater vistas akin to those in tropical-island brochures-bright, clear water, filled with colorful fish. The harsh reality is that most underwater scenes are poorly lit at best, with the norm being dark, monotone and murky.
