Security personnel need to be able to find explosive materials and persons who have been in contact with them. To aid such searches, the National Institute of Standards and Technology (NIST), with support from the Department of Homeland Security, has developed a new certified reference material, Standard Reference Material (SRM) 2905, Trace Particulate Explosives. Compatible with field and laboratory assay methods, the SRM will be helpful in calibrating, testing and developing standard best...

The holographic structure on the frisbee glistens colorfully. It is unique to this batch and makes the product forgery-proof. Explosives are used to emboss the original pattern into the injection moulding tool. This method can be used to give copy protection to industrial goods, and also mass-produced goods such as DVDs or medical pills and tablets. The patented technology was developed by Gnter Helferich of the Fraunhofer Institute for Chemical Technology ICT in Pfinztal. He will receive one...

Israeli chemists have engineered new molecules that can be used to detect microscopic signs of cancer, as well as explosive materials and water pollutants. The Tel Aviv University researchers said both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts that are too small for conventional detection techniques. But now the scientists say they've developed a molecule that can magnify weak traces of such tiny molecules into something that can...

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...

The most abundant material on Earth exhibits some unusual chemical properties when placed under extreme conditions. Lawrence Livermore National Laboratory scientists have shown that water, in hot dense environments, plays an unexpected role in catalyzing complex explosive reactions. A catalyst is a compound that speeds chemical reactions without being consumed. Platinum and enzymes are common catalysts. But water rarely, if ever, acts as a catalyst under ordinary conditions. Detonations of...

U.S. and Danish scientists say they have discovered a way to sensitively detect explosives based on the physical properties of their vapors. The researchers said their technology, which is being developed into prototype devices for field testing, is capable of trace detection of explosives. Certain classes of explosives have unique thermal characteristics that help to identify explosive vapors in presence of other vapors, said Thomas Thundat, a researcher at the Oak Ridge National Laboratory...

 A group of researchers in Tennessee and Denmark has discovered a way to sensitively detect explosives based on the physical properties of their vapors. Their technology, which is currently being developed into prototype devices for field testing, is described in the latest issue of the journal Review of Scientific Instruments, which is published by the American Institute of Physics (AIP)."Certain classes of explosives have unique thermal characteristics that help to identify explosive...

WASHINGTON, Dec. 31 /PRNewswire-USNewswire/ -- The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) published a notice in the Federal Register today containing the list of 238 explosive materials that are subject to federal law and implementing regulations. The annual list is comprehensive but not all-inclusive. Therefore, an explosive material may not be on the list but may still be within the coverage of the law if it meets the statutory definitions. The list covers...

An office worker in Worcester, England, kept a World War I shell as a paperweight for years without knowing it was still live, a friend says. Jon Williamson said his friend, Jeff Heyes, had unknowingly put his own life in danger by keeping the live shell on his desk, using the potentially deadly item as a simple paperweight, the Daily Mail said Friday. Williamson said it was not until he saw the shell that its potential danger became apparent to Heyes, who had the item removed by area...

Dynamite, invented by Swedish chemist Alfred Nobel in 1867, is an explosive that harnesses the potential of nitroglycerin to explode. Normally it is sold in an 8 inch long stick and weighs about .6 pounds although other sizes do exist. TNT is usually the standard by which explosive power is gauged; however, dynamite actually has more than 60% greater energy density than TNT. Nitroglycerin dissolved in nitrocellulose and a small amount of ketone can form another type of dynamite. This type...
