• Seismic shieldLarge-scale metamaterials could earthquake-proof buildings in tremor-prone regions

    Metamaterials – artificial structures that exhibit extraordinary vibrational properties – could come to the rescue of regions threatened by earthquakes, according to new research. The study, performed by researchers in Europe and involving detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks.

  • Fuel cellsWider temperature tolerance is based on ion-pair-coordinated polymers

    A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

  • Security appsSayVU security app – developed by a BGU graduate student -- deployed at Rio Olympics

    A new app, SayVU, conceived as a graduate student project at Ben-Gurion University of the Negev, is being deployed at the 2016 Rio Olympics. International Security & Defense Systems (ISDS), the security integrator for the Olympics, selected SayVU as one of the Israeli technologies being used to protect attendees. SayVU enables a user to send a distress signal to an emergency hotline even if a phone is locked and without having to access the application. The message can be sent in a number of ways; shaking the device, tapping the camera button, or simply speaking into the phone.

  • First response technology“Liquid fingerprinting” technique identifies unknown liquids instantly

    A new company — Validere — will commercialize sensing technology invented at Harvard University that can perform instant, in-field characterization of the chemical make-up and material properties of unknown liquids. Validere aims to develop the licensed technology, called Watermark Ink (W-INK), into a pocket-sized device that could be used by first responders to quickly identify chemical spills, or by officials to verify the fuel grade of gasoline right at the pump.

  • DronesSuccessful flight test of UAV with mass-actuated controls

    For the first time an unmanned aerial vehicle that uses moving weights in its wings, instead of traditional control surfaces or ailerons to turn, was successfully flight-tested. A recently graduated University of Texas at Arlington student  used existing UTA research to design, build, and test a UAV that uses mass actuation — weights that move back and forth within the wings to change the center of gravity from side to side — to turn while airborne.

  • CounterterrorismRemotely disabling non-cooperative vehicles

    As they strive to keep the public safe, one of the key challenges facing European security services is the ability to control and stop, at distance, non-cooperative vehicles posing a threat. However, this ability presents more than a technical challenge. To comply with EU legislation, as well as adhere to ethical concerns, the technology would also have to be safe for the user, the driver (and passengers), as well as members of the public and the material infrastructure of the surrounding environment. In lab bench testing, researchers evaluated signal frequency, waveform, and duration — principally of electromagnetic pulses (EMP) and high power microwaves (HPM) — to determine which could best disrupt the functioning of a vehicle’s electronic components.

  • Guns3D printing: a new threat to gun control and security policy?

    By Daniel C. Tirone and James Gilley

    The threat of self-manufactured firearms is not new, but a critical barrier is collapsing. Until recently, most people did not have the skills to make a weapon as capable as commercially available ones. However, recent developments in the field of additive manufacturing, also known as 3D printing, have made home manufacturing simpler than ever before. The prospect of more stringent gun safety legislation is also fueling interest in at-home production. The worst threats 3D printing poses to human life and safety are likely some distance in the future. However, the harder policymakers and others work to restrict access to handguns or unconventional weapons, the more attractive 3D printing becomes to those who want to do harm.

  • R&DDHS report highlights R&D priorities for technologies used in the field

    The Department of Homeland Security has released the Integrated Product Teams for Department of Homeland Security R&D Fiscal Year 2016 Report. The report identifies twenty-four focus areas for technological research and development (R&D), which fall under five mission areas: aviation security, biological threats, border security, cybersecurity, and counterterrorism.

  • DetectionSuper-sniffer mice detect land mines, decode human olfactory system

    Researchers have created super-sniffer mice that have an increased ability to detect a specific odor. The mice, which can be tuned to have different levels of sensitivity to any smell by using mouse or human odor receptors, could be used as land-mine detectors or as the basis for novel disease sensors.

  • Explosive detectionCan next-generation bomb ‘sniffing’ technology outdo dogs on explosives detection?

    By David Atkinson

    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. What researchers have wanted to develop for a long time is a new chemical detection technology that could “sniff” for explosives vapor, much like a canine does. Many efforts over the years fell short as not being sensitive enough. My research team has been working on this problem for nearly two decades – and we’re making good headway. Inspired by the tremendous detection capabilities of dogs, we’ve made remarkable advances toward developing technology that can follow in their footsteps. Deploying vapor analysis for explosives can both enhance security levels and provide a less intrusive screening environment. Continuing research aims to hone the technology and lower its costs so it can be deployed at an airport near you.

  • DetectionSpeedy terahertz-based system could detect explosives

    By Larry Hardesty

    Terahertz spectroscopy, which uses the band of electromagnetic radiation between microwaves and infrared light, is a promising security technology because it can extract the spectroscopic “fingerprints” of a wide range of materials, including chemicals used in explosives. Spectroscopic system with chip-scale lasers cuts detection time from minutes to microseconds.
