New International Building Codes Address Fire Safety And Evacuation Issues For Tall Structures
2008-10-03 00:00:00.0
Science Daily:Construction News
Future buildings -- especially tall structures -- should be increasingly resistant to fire, more easily evacuated in emergencies, and safer overall thanks to 23 major and far-reaching building and fire code changes approved recently by the International Code Council based on recommendations from the Commerce Department's National Institute of Standards and Technology. The recommendations were part of NIST's investigation of the collapses of New York City's World Trade Center towers on Sept. 11, 2001. ...read more

Researchers are working to create electronic systems that can diagnose and heal their own faults in ways similar to the human immune system. The project is called SABRE (Self-healing cellular Architectures for Biologically-inspired highly Reliable Electronic systems). ...read more
Cautionary Note In Use Of Carbon Nanotubes As Interconnects
2008-09-16 00:00:00.0
Science Daily:Construction News
Researchers have used scanning tunneling microscopy to confirm remarkable changes in the fundamental electronic behavior when double-walled carbon nanotubes are subject to radial deformations and torsional strain. The work reported in Nano Letters reveals that squashing and twisting a double-walled nanotube opens an electronic band gap in an otherwise metallic system, which has major ramifications on the use of carbon nanotubes for electronic and NEMS applications. ...read more
