  • Magnetic liquids improve energy efficiency of buildings
    on January 16, 2018 at 2:36 pm

    Climate protection and the reduction of carbon dioxide emissions have been on top of global development agendas. Accordingly, research and development projects have been conducted on national and international levels, which aim for the improvement of the CO2-footprint in diverse processes. Apart from particularly energy-intensive sectors of the industry, the building sector in particular is among the biggest CO2-emmitters: from residential homes, manufacturing facilities and storage depots to big commercial buildings, about 40 percent of the energy consumption within the EU are due to the heating, cooling, air conditioning and lighting of buildings.

  • Slow 'hot electrons' could improve solar cell efficiency
    on January 16, 2018 at 1:50 pm

    Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy is lost very fast, as it is converted into heat so it does not contribute to the voltage. Researchers have now found a material in which these hot electrons retain their high energy levels for much longer. […]

  • Solar fuels: better efficiency using microwires
    on January 15, 2018 at 5:16 pm

    Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place. […]

  • Panning for silver in laundry wastewater
    on December 20, 2017 at 5:17 pm

    Silver nanoparticles are being used in clothing for their anti-odor abilities but some of this silver comes off when the clothes are laundered. The wastewater from this process could end up in the environment, possibly harming aquatic life, so researchers have attempted to recover the silver. Now, one group reports that detergent chemistry plays a significant role in how much of this silver can be removed from laundry wastewater. […]

  • A functional genomics database for plant microbiome studies
    on December 19, 2017 at 7:44 pm

    Most of the interaction between microbes and plants occurs at the interface between the roots and soil. Biologists have isolated novel bacteria from plant root environments and combined the new genomes with thousands of publicly available genomes representing the major groups of plant-associated bacteria, and bacteria from plant and non-plant environments. Through the resulting database, researchers identified genes enriched in the genomes of plant-associated and root-associated organisms. […]
