• To overcome these deficiencies, a Voxtel team has developed a series of CBE taggants composed of metal oxide and semiconductor nanocrystal (NC) quantum dots, which are coupled to custom-designed bio(chemical)-functionalized ligand tethers, that are sensitive to a series of biological, chemical, and explosive agents. (epa.gov)
  • in comparison with lead azide, copper azide is even more explosive and too sensitive to be used commercially. (cdc.gov)
  • ORNL also produced the Raman Tunable Integrated Sensor (RAMiTS) used by inspectors and first responders to detect chemical agents (including explosive agents). (faqs.org)
  • Researchers at the Oak Ridge National Laboratory in Oak Ridge, Tennessee, test a portable chemical and biological agent monitor developed for the army and marines in 2001. (faqs.org)
  • Next, field demonstrations will be conducted to demonstrate the ability of these CBE taggants to detect the CBE agent at 2.5 km or more. (epa.gov)
  • In the proposed program, the sensitivity of the CBE taggant to CBE agents will be demonstrated, and the specificity and false alarm rate (FAR) will be characterized. (epa.gov)
  • Overall, results suggested that solvent extraction efficiency of explosives in plant was influenced by plant species and solvent used, and method presented here was believed to provide the preliminary data with respect to the analysis of simultaneous explosives in plants with LC-MS/MS. (mst.edu)
  • Maintenance personnel should be advised that the drain is potentially contaminated with explosive agents and caustic material. (cdc.gov)
  • Leveraging its work in taggants, Voxtel proposes to first develop a small-sized CBE colorimetric technology, that is used as a spray or coating, employing a biotaggant that does not undergo color change when an agent is present. (epa.gov)
  • Explosives frequently included small metal parts, increasing severity of injuries, challenging both physicians and healthcare systems. (nih.gov)
  • Today we manufacture a full line of industrial explosives and accessories, and provide technical and blasting services to customers throughout North America and around the world. (austinpowder.com)
  • The agent, whose name hasn't been released, was shot once in the face and is expected to make a full recovery. (myjournalcourier.com)
  • In the presence of a CBE agent, the bioconjugated ligand releases the quenching compound, and a unique optical signature is released that is easily detectable by the eye at short ranges or by LIDAR at longer ranges. (epa.gov)
  • To increase the chances of finding credible leads, some Special Agents spend time building relationships with informants. (atf.gov)
  • D. All Special Agents spend time building relationships with informants. (atf.gov)
  • E. None of the investigators who spend time building relationships with informants are special agents. (atf.gov)
  • Response "D" is cannot be inferred because the paragraph does not support the statement that all special agents spend time building relationships with informants. (atf.gov)
  • It may be that some special agents do not spend time building relationships with informants. (atf.gov)
  • A purported street-gang member charged in the shooting of an ATF agent in Chicago had opened fire as authorities conducted a middle-of-the-night "covert" operation to fit a tracking device on a vehicle, according to charging documents made public Tuesday. (myjournalcourier.com)
  • During an investigation, a lead will be investigated if, and only if, it is deemed credible by a Special Agent. (atf.gov)
  • C. If it is determined that a lead will not be investigated, then the lead was deemed credible by a Special Agent. (atf.gov)
  • Response "C" cannot be inferred because the paragraph does not provide information about the circumstances under which a lead will not be investigated if it was deemed credible by a special agent. (atf.gov)
