  • New findings move flexible lighting technology toward commercial feasibility
    Organic light-emitting diode (OLED) technology holds promise for developing residential and commercial lighting options with greatly enhanced levels of flexibility as well as environmental, health, and cost benefits -- but challenges remain. A new article identifies next steps toward solving those challenges and reaching commercial feasibility.

  • Solar water-splitting technology developed
    Researchers have demonstrated an efficient new way to capture the energy from sunlight and convert it into clean, renewable energy by splitting water molecules. The technology uses sunlight-harvesting gold nanoparticles.

  • Long-sought chiral anomaly detected in crystalline material
    Evidence for a long-sought phenomenon -- first theorized in the 1960s and predicted to be found in crystals in 1983 -- called the 'chiral anomaly' in a metallic compound of sodium and bismuth has been presented by scientists. The researchers also found an increase in conductivity in the material that may suggest ways to improve electrical conductance and minimize energy consumption in future electronic devices.

  • Self-sweeping laser could dramatically shrink 3-D mapping systems
    Researchers are using light to move mirrors, a novel concept to automate the way a light source changes its wavelength as it sweeps the surrounding landscape. The advance could have implications for imaging technology using LIDAR.

  • Microscopic animals inspire innovative glass research
    When researchers set about to explain unusual peaks in what should have been featureless optical data, they thought there was a problem in their calculations. In fact, what they were seeing was real. The peaks were an indication of molecular order in a material thought to be entirely amorphous and random: their experiments had produced a new kind of glass.

  • How to curb emissions: Put a price on carbon
    Literally putting a price on carbon pollution and other greenhouse gasses is the best approach for nurturing the rapid growth of renewable energy and reducing emissions. While prospects for a comprehensive carbon price are dim, especially in the US, many other policy approaches can spur the renewables revolution, according to a new policy article.

  • Metallic gels produce tunable light emission
    New tunable luminescent gels could find use in chemical, biological detectors.

  • Gas sensors sound the smoldering fire alarm
    Smoke detectors are everywhere, but still thousands of people die in fires annually. Fire gas detectors, which detect carbon monoxide and nitrogen oxide, identify fires at an early stage. Thanks to a new measurement principle, these costly sensors will soon be inexpensive and ready for the mass market.

  • Wastewater to irrigate, fertilize and generate energy
    To meet the requirements of Asian cities, researchers are adapting an idea they have already applied in Germany for comprehensive water management: developing a concept for reducing water use, treating wastewater and extracting fertilizer for a strip of coastline in the Vietnamese city of Da Nang.

  • Making fuel from light
    Photosynthesis has given life to the planet. While scientists have been studying and mimicking the natural phenomenon in the laboratory for years, understanding how to replicate the chemical process behind it has largely remained a mystery -- until now.
