Technology Produces Unclonable Digital Fingerprints for Internet of Things Devices

  • Magazine Article
  • TBMG-34932
Published 2019-08-01 by Tech Briefs Media Group in United States

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to authenticate devices linked to the Internet of Things (IoT).

Palm-Sized 3D Ultrasound for Scoliosis Mass Screening

  • Magazine Article
  • TBMG-34968
Published 2019-08-01 by Tech Briefs Media Group in United States

Researchers have developed a first-of-its-kind palm-sized 3D ultrasound imaging system for radiation-free scoliosis assessment. Named “Scolioscan Air,” the system is designed to bring accurate, safe and cost-efficient mass screening to schools and communities.

Combustion Gas Heat Exchanger

  • Magazine Article
  • TBMG-34897
Published 2019-08-01 by Tech Briefs Media Group in United States

Two very challenging problems facing the U.S. and the world are energy security and global climate change, largely due to dependence on fossil fuels. Cost-effective technologies have been developed that are capable of substantial energy savings through improved energy efficiency.

Microturbine Propulsion for UAVs

  • Magazine Article
  • TBMG-34863
Published 2019-08-01 by Tech Briefs Media Group in United States

Seventy years ago, military aviation moved from reciprocating engines to vastly more reliable turbo jets and turboprops. Shortly after, the commercial air transport industry followed suit, enabling modern air transport. Today, virtually all large aircraft rely on turbine propulsion, yet small aircraft, both manned and unmanned, have not exploited the advantages of turbines for propulsion.

Process Directly Converts Methane to Methanol

  • Magazine Article
  • TBMG-34934
Published 2019-08-01 by Tech Briefs Media Group in United States

Methanol is a key feedstock for the production of chemicals, some of which are used to make products such as plastics, plywood, and paints. Methanol also can fuel vehicles or be reformed to produce high-grade hydrogen for fuel cells. The current method for producing methanol from methane- or coal-derived synthesis gas involves a multi-step process that is neither efficient nor economical in small-scale applications. As a result, methane emissions from oil wells — accounting for 210 billion cubic feet of natural gas annually — are being vented and flared, according to the U.S. Energy Information Administration.

Capturing Unique Device Identifier Data on Non-Sterile Orthopedic Implants

  • Magazine Article
  • TBMG-34970
Published 2019-08-01 by Tech Briefs Media Group in United States

Now that medical devices are being labeled and uniquely identified to meet the requirements of the U.S. Food and Drug Administration (FDA) Unique Device Identifier (UDI) Rule, healthcare providers have an opportunity to capture and leverage the data contained in these unique device identifiers (UDIs) to improve the quality of care.

High-Temperature Dielectric Nanocomposite

  • Magazine Article
  • TBMG-34899
Published 2019-08-01 by Tech Briefs Media Group in United States

A nanocomposite was developed that could be a superior high-temperature dielectric material for flexible electronics, energy storage, and electric devices. The nanocomposite combines one-dimensional polymer nanofibers and two-dimensional boron nitride nano-sheets. The nanofibers reinforce the self-assembling material while the white graphene nanosheets provide a thermally conductive network that allows it to withstand the heat that breaks down common dielectrics, the polarized insulators in batteries, and other devices that separate positive and negative electrodes.
