Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Electron self-injection into an evolving plasma bubble
Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. view more (2009-11-03)
High-performance plasmas may make reliable, efficient fusion power a reality
In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. view more (2009-11-03)
LANL Roadrunner models nonlinear physics of high-power lasers
For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers to high enough pressure and temperature to initiate fusion burn. view more (2009-10-29)
How to identify early graft dysfunction preoperatively?
Small-for-size graft dysfunction (SFSGD) following living-related liver transplantation (LRLT) is characterized by early graft dysfunction (EGD) when the graft-to-recipient body weight ratio (GRBWR) is below 0.8%. view more (2009-10-16)
