  • A poison helps to understand H2-producing biocatalysts

    In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore of interest for biobased hydrogen production. Although scientists have learned a lot about how these enzy more

  • Gold from old phones is real prospect thanks to chemical advance

    Vast quantities of gold could be salvaged from old mobile phones using a simple chemical method, a study shows. Current methods for extracting gold from old gadgets are inefficient and can be hazardous to health, as they often use toxic chemicals such as cyanide, researchers say. Electrical waste - more

  • Highly efficient heavy metal ions filter

    ETH researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. In November, Brazil experienced an unp more
