• Advances in the use of photocatalysts to help keep water clean safe

    Photocatalysis involves the acceleration of chemical reactions using the power of light; researchers experiment with different types of photocatalysts to reduce nitrates in water

  • Preventing earthquake-induced soil liquefaction to protect buildings

    When earthquakes occur, buildings can shift or fall; often, the failure is because of soil liquefaction, a phenomenon that occurs when loose, water-saturated soils lose strength in response to the sudden shaking from an earthquake, causing the soil to behave like a liquid; scientists have come up with a way to minimize liquefaction

  • Shape-memory alloys for earthquake-resistant structures

    To improve the performance of structures during earthquakes, researchers have been investigating the use of “smart” materials, such as shape-memory alloys, which can bounce back after experiencing large loads

  • Nuclear accidents pose “essentially zero risk" to public health

    A new study by the U.S. Nuclear Regulatory Commission (NRC) concluded that there is only a “very small” risk to public health if a severe nuclear accident were to occur in the United States

  • A solution for troubled ITER nuclear fusion reactor

    Nuclear fusion offers the promise of endless energy supply – but the technology requires extremely high temperatures of up to 150 million degrees in order to form plasma (ionized gas); since no material can withstand these temperatures, the fuel (a mixture of two isotopes of hydrogen: deuterium and tritium) must be kept trapped in extremely energetic magnetic fields; the magnets that produce these fields are composed of giant coils of superconducting cables; so far, the superconducting cables designed for the European ITER fusion reactor have been unable to withstand the planned 40,000 to 60,000 charge cycles

  • Local officials oppose “unacceptable” levee ratings

    In recent years as part of an effort to bolster the nation’s flood protection infrastructure, the Army Corps of Engineers has analyzed and declared more than 200 levee systems across the country as “unacceptable,” resulting in a firestorm of criticism from local officials

  • Bill would allow DHS to impose cybersecurity standards

    A bill before Congress would significantly increase the power of DHS to monitor the cybersecurity practices of industries and services which are part of the U.S. critical infrastructure

  • The cost of bolstering U.S. infrastructure cyber-protection

    To achieve security capable of stopping 95 percent of cyber attacks on U.S. critical infrastructure – 100 percent protection is not attainable – experts said the industries involved would have to boost spending to a group total of $46.6 billion from the current $5.3 billion

  • Compressed natural gas as transportation fuel

    A number of different fuel sources — ethanol, biodiesel, electricity, and hydrogen — have each shown their promise as an alternative to petroleum; scientists at Argonne Lab want to add one more contender to the list of possible energy sources for light-duty cars and trucks: compressed natural gas (CNG)

  • Critical infrastructure operators must double cybersecurity spending: report

    A new study finds that critical infrastructure operators in the United States are massively under spending on cybersecurity

  • Scientists develop new concrete corrosion sensors

    Scientists have made a major breakthrough in developing sensors which dramatically improve the ability to spot early warning signs of corrosion in concrete; the sensors will make monitoring the safety of structures such as bridges and vital coastal defenses much more effective

  • Smart paint monitors structural safety

    An innovative low-cost smart paint that can detect microscopic faults in wind turbines, mines, and bridges before structural damage occurs; the environmentally friendly paint uses nanotechnology to detect movement in large structures, and could shape the future of safety monitoring

  • Massive solar storm leaves critical infrastructure largely unharmed

    Last week critical infrastructure operator’s dodged a bullet when a colossal solar storm sent a flood of highly-charged protons hurtling at the earth; critical infrastructure operators had braced for the worst, but the storm only resulted in minimum disruptions to the world’s energy grid and transportation systems

  • Pepco buys solar competition prize-winning building for display

    WaterShed, a prize-winning, energy-saving house designed by a team from the University of Maryland, has been bought by Pepco; the utility will maintain the building and open ot for public display

  • Sea water could corrode nuclear fuel

    Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 — and that was probably the best action to take at the time; scientists have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles
