    • Spontaneous combustion in nanobubbles inspires compact ultrasonic loudspeaker (ScienceDaily)- September 28, 2011
    • Nanometre-sized bubbles containing the gases hydrogen and oxygen can apparently combust spontaneously, although nothing happens in larger bubbles. For the first time, researchers at the University of Twente's MESA+ Institute for Nanotechnology have demonstrated this spontaneous combustion in a publication in Physical Review E. More...
    • Energy efficiency in building and cities (ScienceDaily)- September 28, 2011
    • Sustainable energy consumption, the use of renewable energies, energy efficiency and the reduction of CO2 emissions are the current challenges that cities and communities must overcome if they want to achieve the ambitious energy and climate targets if they want to achieve the set out by the EU in their EU 2020 strategy. More...
    • Simulating turbulent combustion speeds design (PhysOrg)- September 22, 2011
    • A team led by mechanical engineers Joseph Oefelein and Jacqueline Chen of Sandia National Laboratories (Sandia) simulates turbulent combustion at different scales. A burning flame can manifest chemical properties on small scales from billionths of a meter up to thousandths of a meter, whereas the motion of an engine valve can exert effects at large scales from hundredths of a meter down to millionths of a meter.

    • Microwave ovens a key to energy production from wasted heat (Eurekalert)- September 20, 2011
    • More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat – an age-old problem - but researchers have found a new way to make "thermoelectric" materials for use in technology that could potentially save vast amounts of energy. And it's based on a device found everywhere from kitchens to dorm rooms: a microwave oven. More...
    • Big step towards redefining the Kelvin: scientists find new way to determine boltzmann constant (ScienceDaily)- September 20, 2011
    • Metrologists are measurement artists who are very precise -- in the case of the Boltzmann constant up to the sixth decimal place. Whoever is able to determine it very exactly will cause a small revolution in the field of worldwide temperature measurement: The temperature unit will then no longer be based -- as before -- on a chemico-physical material property, i.e. the triple point of water, but on an unchangeable fundamental constant. More...
    • Innovative superconductor fibers carry 40 times more electricity (e! Science News)- September 7, 2011
    • Wiring systems powered by highly-efficient superconductors have long been a dream of science, but researchers have faced such practical challenges such as finding pliable and cost-effective materials. Now researchers at Tel Aviv University have found a way to make an old idea new with the next generation of superconductors. More...
    • Quake-prone Japan Looks At Geothermal Energy (PhysOrg)- August 26, 2011
    • Kazuhiro Takase shows AFP around Japan's first geothermal plant at Hachimantai city in Iwate prefecture. The forces that make Japan one of the world's most quake-prone and volcanic countries, and sparked a nuclear disaster, could become part of its long-term energy solution, experts say. More...
    • Solar Furnaces: A Powerful Use of Solar Power (RenewableEnergyWorld)- August 25, 2011
    • Solar power can be used in many extraordinary ways. One of the most majestic applications of solar thermal energy is the solar furnace. These are enormous installations that make use of solar thermal energy for extreme high heat processes (temperatures as high as 3500oC/6330oF). More...
