Nanotubes promise fuel from water
News & Analysis  
3/25/2005   Post a comment
Sandia National Laboratories recently demonstrated that hollow organic nanotubes, married to an inorganic catalyst, can harness sunlight to turn water into pure hydrogen and oxygen. By 2006, Sandia researchers hope to have prototypes from which a new kind of solar cell could be made that would convert water into fuel.
Research looks to avert nanoparticle pollution
News & Analysis  
3/21/2005   Post a comment
Critics of nanotechnology have fastened onto speculation by Sun Microsystems co-founder Bill Joy about runaway nanobots turning the planet into "gray goo," tainting the technology in all its forms. Now, cooperating engineering teams at the Georgia Institute of Technology and Rice University are angling to find out if that's so. Their preliminary results in measuring the behavior of nanomaterials in the environment show that the threats are real, but so is the hope of preventive solutions.
Algorithm colorizes automatically
Product News  
3/14/2005   Post a comment
An algorithm that simplifies the labor-intensive task of colorizing black-and-white motion pictures has been created at Hebrew University in Jerusalem. The algorithm lets simple scribbles accomplish what would otherwise demand exacting definition.
Nanowires corralled for interconnect tasks
News & Analysis  
3/14/2005   Post a comment
A research group at the University of Delaware has demonstrated a way to precisely position and control the growth of organic nanowires atop a prepatterned substrate, potentially providing a means of interconnecting future nanocircuits.
Nanotubes enable dense supercapacitors
News & Analysis  
3/7/2005   Post a comment
Using conventional materials-processing technology as a foundation, researchers at the University of California-Davis have developed nanotube-based thin films to build capacitors with a power density of 30 kilowatts per kilogram, a tenfold increase over previous devices.
Intel targets multithreaded software for multicore processors
News & Analysis  
3/3/2005   Post a comment
Intel Corp. Senior Fellow Justin Rattner predicted that future multicore processors will divide and conquer rather than depend faster single-processor speeds.

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
