Effective and accurate detection of trace explosives is crucial in the effort to thwart terrorist explosives attacks. A National Institute of Standards and Technology (NIST) standard reference material (SRM) has been developed for the evaluation of trace explosives detectors that sample by collection of residue particles using swiping or air filtration. SRM 2907 Trace Terrorist Explosives Simulants consists of two materials individually simulating the residues of the plastic explosive Semtex [for pentaerytritol tetranitrate (PETN)] and the improvised explosive triacetone triperoxide (TATP). Unique challenges were encountered in the development of these materials, including the selection of suitable inert substrates, material preparation, thermal stability testing, and analytical method development. Two independent analytical methods based on liquid chromatography with ultraviolet absorbance and mass spectrometric detection, LC-UV and LC/MS, respectively, were developed and used to certify the mass fractions of PETN and TATP. These materials were further evaluated for their suitability on a field swipe-sampled trace explosives detectors based on ion mobility spectrometry (IMS).

Chemical industries are highly vulnerable to accidental events or terrorist attacks due to their processing, storage, and transportation of explosive, flammable, and toxic materials. Major industrial risks include fire, explosion, and toxic chemical release. An effective risk evaluation system is essential to prevent accidents or terrorist attacks.

Increasing attention has been paid to the detection of explosives due to the occurrence of terrorist attacks around the world. Here, we used free radical polymerization to develop two different types of fluorescent copolymers for use in detecting picric acid. One exhibits aggregation-caused quenching (ACQ) and is called PNNS [poly (-isopropyl acrylamide---hydroxymethyl acrylamide --styrene-pyrene), poly (NIPAAm--NMA--St-Py)].

Introduction: The terror attack on October 7, 2023, in southern Israel resulted in approximately 1,200 civilians and security personnel killed. Of the civilians murdered, approximately 200 men, women, and children were murdered inside their homes, while the remaining casualties were murdered in an open field at a music festival, in their cars, or in the streets of local cities.
Materials And Methods: Currently, official data have not yet been published regarding the types of injuries suffered by Israeli civilians during the terror attack.

Metal-containing compounds form a large and rapidly expanding group of high-energy materials. Many compounds in this class attract the attention of non-professionals, who may attempt the illegal production of explosives. Several of these substances have been commercially available and pose significant danger if used by terrorists or for criminal purposes.
