• Coal waste fuel may reduce anthropogenic emissions, TPU study reveals

    Scientists from Tomsk Polytechnic University are developing a technology for fuel production from coal processing wastes. This fuel is ten times more environmentally friendly that will make it possible to resolve two problems at once: to reduce the amount of anthropogenic emissions of TPSs and efficiently dispose wastes from coal processing and beneficiation. The research team of the Department of Automation of Thermal Power Processes led by Professor Pavel Strizhak shares its outcomes.

  • New method enables real-time monitoring of materials during irradiation

    A new advance on a method developed by MIT researchers could enable continuous, high-precision monitoring of materials exposed to a high-radiation environment. The method may allow these materials to remain in place much longer, eliminating the need for preventive replacement. It could also speed up the search for new, improved materials for these harsh environments.

    The new findings appear in the journal Applied Physics Letters, in a paper by graduate student Cody Dennett and assistant professor of nuclear science and engineering Michael Short. This study builds on the team’s earlier work that described the benchmarking of the method, called transient grating spectroscopy (TGS), for nuclear materials. The new research shows that the technique can indeed perform with the high degree of sensitivity and time-resolution that the earlier calculations and tests had suggested should be possible for detecting tiny imperfections.

  • Keeping the hydrogen coming

    A novel molybdenum-coated catalyst that can efficiently split water in acidic electrolytes is developed by researchers at KAUST and could help with efficient production of hydrogen.

  • Ultra-stable perovskite solar cell remains stable for over a year

    Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22% power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have been achieved. EPFL scientists have now built a low-cost, ultra-stable perovskite solar cell that has operated for more than a year without loss in performance (11.2%). The work is published in Nature Communications.

  • Are Bidets More Environmentally Friendly Than Toilet Paper?

    While bidets remain unpopular in America, they’re a familiar fixture in bathrooms all over the world. And they raise an inevitable question: Is it better for the environment if you wipe, or should you wash instead?

    The answer may surprise you — and could lead you to rethink your next bathroom remodel.

  • Rooftop Solar Panels Are Great for the Planet—But Terrible for Firefighters

    When first responders arrived to the burning home on Eugene Street in Manchester, New Hampshire just after 2 am on January 27, half the home was already up in flames. It was a big fire, but relatively routine: Working in the dark, the firefighters made sure the two residents got out unharmed, and got to work.

  • Argonne scientists make vanadium into a useful catalyst for hydrogenation

    Just as Cinderella turned from a poor teenager into a magnificent princess with the aid of a little magic, scientists at the U.S. Department of Energy’s Argonne National Laboratory have transformed a common metal into a useful catalyst for a wide class of reactions, a role formerly reserved for expensive precious metals.

    In a new study, Argonne chemist Max Delferro boosted and analyzed the unprecedented catalytic activity of an element called vanadium for hydrogenation – a reaction that is used for making everything from vegetable oils to petrochemical products to vitamins.

  • Why Don't Green Buildings Live Up to Hype on Energy Efficiency?

    Not long ago in the southwest of England, a local community set out to replace a 1960s-vintage school with a new building using triple-pane windows and super-insulated walls to achieve the highest possible energy efficiency. The new school proudly opened on the same site as the old one, with the same number of students, and the same head person—and was soon burning more energy in a month than the old building had in a year.

  • Solar-Powered EV Charging Arrives in the San Joaquin Valley

    Some coastal residents might describe Fowler, California, as the middle of nowhere. But it’s smack in the center of the San Joaquin Valley, a region critical for growing food for the rest of the state and much of the U.S. Like much of the Valley, this town of 5,500 people, located a 15-minute drive south of Fresno, struggles with terrible air quality. But a growing movement may soon change that.

  • Printed, flexible and rechargeable battery can power wearable sensors

    Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics. The work appears in the April 19, 2017 issue of Advanced Energy Materials.  

    The researchers made the printed batteries flexible and stretchable by incorporating a hyper-elastic polymer material made from isoprene, one of the main ingredients in rubber, and polystyrene, a resin-like component. The substance, known as SIS, allows the batteries to stretch to twice their size, in any direction, without suffering damage.
