The explosive PETN has been around for a century and is used by everyone from miners to the military, but it took new research by Sandia National Laboratories to begin to discover key mechanisms behind what causes it to fail at small scales. “Despite the fact explosives are in widespread use, there´s still a lot to learn about how detonation begins and what properties of the explosive define the key detonation phenomena,” said Alex Tappan of Sandia´s Explosives...

Locating Landmines And Buried IEDs Made Easier With New Chemical Sensor
2012-08-02 08:09:07

A chemical sensing system developed by engineers at the University of Connecticut is believed to be the first of its kind capable of detecting vapors from buried landmines and other explosive devices with the naked eye rather than advanced scientific instrumentation. The research was first reported in the May 11, 2012 online edition of Advanced Functional Materials. The key to the system is a fluorescent nanofiberous film that can detect ultra-trace levels of explosive vapors and buried...

The National Institute of Standards and Technology (NIST) has released a new standard reference material (SRM) to aid in the detection of two explosive compounds that are known to be used by terrorists. Researchers designed the new test samples to simulate the size and behavior of residues that remain after handling the explosives PETN (pentaerythritol tetranitrate) and TATP (triacetone triperoxide). Instrument developers, academic researchers and government labs can use the SRM to test,...

U.S. lawmakers say the use of body scanners at airport security points is likely to be revisited after a would-be attacker smuggled explosives aboard a plane on Christmas Day, AFP reported. The controversial machines, which can scan beneath clothing to detect items that may be hidden from ordinary view, are considered effective and have been tested at numerous international airports. Most security experts say the scanners likely would have detected the explosives that Umar Farouk...

U.S. government scientists say they've shown that water in hot dense environments acts as a catalyst, speeding chemical reactions without being consumed. Lawrence Livermore National Laboratory scientists said although the properties of pure water at high pressures and temperatures have long been studied, water in a reactive environment had never been researched. Lead scientist Christine Wu said she and her team studied the detonation of the high explosive pentaerythritol tetranitrate and...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'
