  • Gases Excluded from Montreal Climate Deal Are Harming Ozone, Researchers Say

    A report finds that a man-made chemical, dichloromethane, which is not included in a United Nations treaty aimed at protecting the ozone layer, is contributing to ozone depletion.

  • Engineering Buildings That Rock in an Earthquake

    Buildings that rock during an earthquake and return to plumb would withstand seismic shaking better than structural designs commonly used in vulnerable zones, according to a researcher at Case Western Reserve University in Ohio.

  • Hawaiian Utility to Double Its Solar Hosting Capacity

    Hawaiian Electric Cos. (HECO) is proposing to double its hosting capacity for solar energy. The utility announced its intentions in late January to increase its penetration limits for rooftop solar minimum daytime load (MDL) from 120% to 250% of MDL. Those increases would be among the highest thresholds for solar penetration on distribution circuits in the U.S.

  • Bendable Implant Taps Nervous System without Damaging It

    Body implants that can interface with the nervous system run up against a basic material problem: wires are stiff and bodies are soft. Researchers at the École Polytechnique Fédérale, in Lausanne, Switzerland, have designed a soft, flexible electronic implant, which they say has the same ability to bend and stretch as dura mater, the membrane that surrounds the brain and spinal cord.

  • Method Recovers High-value Metals for Industry

    Researchers at the University of Guanajuato (UGTO) in Mexico have developed an extraction column which recovers metals companies use in their production processes to avoid environmental pollution and lessening economic losses.

  • Device Could Strengthen Security Screening Capabilities

    Engineers at Northwestern University built a compact version of a device that uses terahertz waves for the purpose of imaging, to identify explosives, chemical agents and dangerous biological substances from safe distances.

  • Nanoscale Mirrors Make Data Transfers More Secure

    New research performed at the Massachusetts Institute of Technology (MIT) and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory reveals the constructing of tiny "mirrors" to trap light around impurity atoms in diamond crystals, the team dramatically increased the efficiency with which photons transmit information about those atoms' electronic spin states, which can be used to store quantum information.

  • Safran Opens Research and Technology Center

    Safran has inaugurated a research and technology center in Paris, France, to focus on electric aircraft, new aircraft propulsion architectures and information and communications technologies.

  • Kevlar Barrier Could Lead to Safer Lithium-ion Batteries

    The battery technology innovation is an advanced barrier between the electrodes in a lithium-ion battery, reports University of Michigan.

  • Carbon Sequestration: Less Rock Created than Expected?

    Carbon sequestration is a process that injects carbon dioxide deep below the Earth’s surface where it solidifies into rock.

  • Engineers Aim to Bring "Cold Spray" 3D Printing to Space

    A team of engineers from Trinity College Dublin are leading a project to fine-tune “cold spray” (CS), a technology that deposits materials onto engineering components.

  • Engineers Build a Hand-held Lab

    Engineers at University of British Columbia’s (UBC) Okanagan campus have developed a lab powerful enough to look at microscopic drops of fluid and identify harmful pathogens, like those responsible for HIV, AIDS, and hepatitis, but also small enough to fit in your hand.

  • Signal Amplification Process Could Transform Communications

    Researchers at the University of California, San Diego (USCD), say they have discovered a new signal amplification process that may fuel new generations of electrical and photonic devices.

  • Software That Suggests Low-risk Alternatives

    Imagine that you could tell your phone that you want to drive from your house in Boston to a hotel in upstate New York, that you want to stop for lunch at an Applebee's at about 12:30, and that you don't want the trip to take more than four hours.

  • Laser-induced Graphene Shows Promise for Electronics

    Rice University scientists in Houston say they have advanced their recent development of laser-induced graphene (LIG) by producing and testing stacked, 3D supercapacitors, energy-storage devices that are important for portable, flexible electronics.

  • Mechanism to Counter Corrosion in Metals Discovered

    A new study reveals that certain characteristics of metal surfaces can stop the process of oxidation in their path.

  • Your Smart Phone as Medical Lab Instrument

    High-priced microscopes, spectrometers and chromatography devices get all the attention in lab equipment circles.

  • Computer Network Rivals Primate Brain in Object Recognition

    Primates visually recognize and determine the category of an object at a brief glance, and to date, this behavior has been unmatched by artificial systems. A study published in PLOS Computational Biology has found that the latest artificial "deep neural network" performs as well as the primate brain.

  • NREL Claims 45.7% Efficiency for Concentrator Solar Cell

    The U.S. Energy Department's National Renewable Energy lLaboratory has improved the design of its solar cell by adding an additional absorber layer. NREL says this increased the conversion efficiency to 45.7% for a four-junction solar cell at 234 suns concentration.

  • New ASTM Standard for Butanol Purity Testing

    A new ASTM International standard will be used in isobutanol manufacturing to test its purity for use in the chemical and fuel markets.
