With each terrorist attack on another airport, train station or other public space, the urgency to find new ways to detect bombs before they’re detonated ratchets up. Chemical detection of explosives is a cornerstone of aviation security. Typically called “trace Read More …
By mimicking how dogs get their whiffs, government and university researchers have demonstrated that “active sniffing” can improve by more than 10 times the performance of current technologies that rely on continuous suction to detect trace amounts of explosives and Read More …
HARRISBURG, Pa. — A new state-of-the-art advanced technology computed tomography checkpoint scanner (CT) that provides 3-D imaging has been installed and is in use at the Transportation Security Administration (TSA) checkpoint at Harrisburg International Airport. The new technology provides critical Read More …
FOR IMMEDIATE RELEASE S&T Public Affairs, 202-254-2385 Washington, D.C. – With a growing need to improve the security, efficiency and accuracy of passenger and baggage screening, the Department of Homeland Security (DHS) Small Business Innovation Research (SBIR) Program is working with a small Read More …
Whether it’s an airport screening station or in-the-field terrorism investigations, trace detection of explosives – which are chemical compounds – generally involves the collection of vapor or particulate samples from these chemicals and analyzing them using a sensitive sensor system. Read More …
Explosive materials pose a threat whether they are used by domestic bad actors or in a theater of war and staying ahead of our adversaries is a job that the Departments of Homeland Security and Defense share. Our research and Read More …
Two laboratories under the Department of Homeland Security’s science and technology directorate are teaming up to test portable explosives trace detectors. Researchers from the Transportation Security Laboratory validated gaps with the detectors and have spoken with vendors and customers to Read More …
This Defence and Security Accelerator (Accelerator) themed competition seeks to make a real difference in aviation security through innovative science and technology. The competition is looking for proposals to improve our ability to prevent explosives, hidden within electrical items in passenger baggage, from Read More …
University of Michigan researchers have developed a laser-based method that could be used to detect chemicals such as explosives and dangerous gases quickly and accurately. Eventually, this method could be used in systems placed in airports, for the environmental monitoring Read More …
Bomb plots could be thwarted with the help of a portable system for detecting traces of high explosives using fluorescent polymer nanoparticles, developed by A*STAR. Coated on to paper, these polymers display an explosive-detection performance far more robust than previous Read More …
A technology expert has created a computer chip based on mice neurons that could recognise the smell of explosives. The device could be implanted into the brain of future robots, which could be trained to recognise danger via odours, replacing Read More …
