  • Squeezing light improves performance of MEMS sensors

    Microelectromechanical systems, known as MEMS, are ubiquitous in modern military systems such as gyroscopes for navigation, tiny microphones for lightweight radios, and medical biosensors for assessing the wounded. Such applications benefit from the portability, low power, and low cost of MEMS devices. The use of MEMS sensors is now commonplace, but they still operate many orders of magnitude below their theoretical performance limits, due to two obstacles: thermal fluctuations and random quantum fluctuations, a barrier known as the standard quantum limit.

  • Compact, high-power terahertz source at room temperature developed

    Terahertz (THz) radiation — radiation in the wavelength range of 30 to 300 microns — is gaining attention due to its applications in security screening, medical and industrial imaging, agricultural inspection, astronomical research, and other areas. Traditional methods of generating terahertz radiation usually involve large and expensive instruments, some of which also require cryogenic cooling. Researchers have developed a compact, room-temperature terahertz source with an output power of 215 microwatts.

  • The side of Homeland Security you won't see on TV

    The way the Department of Homeland Security is often portrayed in popular culture — surveillance and secret agents — leaves out a crucial aspect of its role. It also works on technology to detect attacks as they are happening, and helps federal and local governments prepare for all kinds of disasters, from hurricanes to accidental chemical spills to anthrax attacks. Argonne Laboratory engineers contribute to this effort, helping local and state governments form emergency plans, run drills for a pandemic flu outbreak in the city of Chicago, and analyzed ways to enhance security at plants and factories across the country.

  • Smartphone “microscope” can detect a single virus, nanoparticles

    Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Researchers have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.

  • U.S. military trains to support civil authorities during domestic CBRN incident

    Vibrant Response 13-2 exercise, conducted by U.S. Northern Command and led by U.S. Army North (Fifth Army), is an annual event and is the country’s largest CBRN exercise. The training exercise is used to evaluate a military unit’s operational and tactical ability to support civil authorities during domestic incidents involving chemical, biological, radiological, or nuclear weapons.

  • Molecule “scanner” uses terahertz radiation to identify single molecules

    Molecules could soon be “scanned” in a fashion similar to imaging screenings at airports, thanks to the world’s smallest terahertz detector, developed by University of Pittsburgh physicists. The scanner has the ability chemically to identify single molecules using terahertz radiation — a range of light far below what the eye can detect.

  • Approaches to international consequence management for CBRNE incidents

    The National Research Council (NRC) of the National Academy of Sciences, through a grant sponsored by NIST’s Office of Law Enforcement Standards (OLES), is organizing an effort to understand the metrics and measures that are needed to develop standards of response that will support the basic capabilities of a country or region to respond to a chemical, biological, radiological, nuclear, or explosive (CBRNE) incident

  • Green laser pointer identifies traces of dangerous chemicals in real time

    By using an ordinary green laser pointer, the kind commonly found in offices and college lecture halls, an Israeli research team has developed a new and portable Raman spectrometer which can detect minute traces of hazardous chemicals in real time; the new sensor’s compact design makes it a candidate for rapid field deployment to disaster zones and areas with security concerns

  • Long Beach Police Department purchases underwater inspection system for port

    The Port of Long Beach is the second busiest seaport in the United States and is a major gateway for trade with Asia, handling more than six million containers annually; to enhance port security, the City of Long Beach Police Department has purchased an Underwater Inspection System (UIS) from Cod Octopus

     

  • Immediate, in-the-field identification of hazardous materials

    Soldiers in war zones, and law enforcement and first responders on the scene will soon have the ability to collect and immediately analyze trace amounts of potentially dangerous chemical, explosive, or biological agents with the help of a surface swabbing device developed and prototyped by a Maine-based technology company with the help of the University of Maine researchers

  • Improved disaster resilience is imperative for U.S: report

    A new report from the National Academies says that it is essential for the United States to bolster resilience to natural and human-caused disasters, and that this will require complementary federal policies and locally driven actions that center on a national vision – a culture of resilience; improving resilience should be seen as a long-term process, but it can be coordinated around measurable short-term goals that will allow communities better to prepare and plan for, withstand, recover from, and adapt to adverse events

  • General Dynamics to integrate CBRN device in Army radios

    General Dynamics C4 Systems announced last week that it will work with U.S. Army researchers to install wireless-networking chips on radios that can also detect the presence of dangerous chemicals on the battlefield

  • Record revenues for Universal Detection Technology

    Last week Universal Detection Technology, which sells early warning monitoring technology for biological, chemical, and radiological threats, announced record high revenues for its most recent quarter

  • Field Forensics launches quick opium detection kit

    Field Forensics Inc., a U.S. developer of explosives detection and containment equipment, recently unveiled a new kit designed to detect a core chemical used to manufacture heroin

  • Floyd County gets additional $75,000 for CBRNE unit

    Floyd County in Georgia has received two DHS grants worth $75,000 to replace and repair equipment for its chemical, biological, radiological, nuclear, and explosives (CBRNE) response unit; the bulk of the money, approximately $65,000, will go towards replacing aging equipment, while the rest will go towards repairs; the CBRNE team was originally created four years ago with nearly $350,000 in DHS funding as part of the state’s terrorism prevention initiative
