  • Uranium from seawater idea boosted with shrimp shells

    Oceans hold billions of tonnes of uranium at tiny concentrations, but extracting it remains uneconomical. A report at the 244th meeting of the American Chemical Society described a new technique using uranium-absorbing mats made from discarded shrimp shells. Uranium is currently mined from ore deposits around the world, but there are fears that demand may outstrip the supply of ore as […]

  • Chitosan used to lengthen shelf life of bananas in China

    Scientists have figured out how to use chitosan — a substance derived from shrimp and crab shells — to delay the ripening of bananas for up to two weeks. Scientists speaking in Philadelphia at the 244th National Meeting & Exposition of the American Chemical Society described experiments designed to develop a spray-on coating that consumers could use themselves. The coating, […]

  • Mantis shrimp key to armour that can take 50,000 bullet impacts

    Military body armour and vehicle and aircraft frames could be improved by incorporating the unique structure of the club-like arm of a crustacean that looks like an armoured caterpillar, say researchers. The club is so strong that it shears the water, literally boiling it, forming cavitation bubbles that implode, yielding a secondary impact on its prey The bright orange fist-like […]

  • Research with shrimp shell may be key to diabetic bandages

    Somewhere, it seems, there should be some humor to be had. What do you get when you combine shrimp, seaweed and a bandage? If you’re Dr. Whitney Hough, it’s a combination that will help diabetics overcome slow-healing sores – known as diabetic ulcers. It’s not a joke in need of a giddy punch line. Hough, a 28-year-old Albertville native, is a […]

  • Shrimp shell nanoparticle combats microbes, heals wounds

    Nanoparticle-sized Chitosan has shown promise in effectively combating Staphylococcus saprophyticus and E. coli. Chitosan is a natural, non-toxic and biodegradable, obtained from chitin, the main component of the shells of shrimp, lobster and the beak of the octopus and squid. It could be used as a protective wound-healing material to avoid opportunistic infection as well as working to facilitate wound […]

  • Breaking Down Crab Shells Could Improve Solar Technology

    At Kyoto University in Japan, researches have found an interesting composite that might just meet these requirements in an unlikely place — a crab shell. A crab shell was put through a number of different chemical washes and was broken down into a material called chitin. The chitin is combined with a resin to create the desired compound. This material […]

  • Pharmaceuticals from crab shells

    Usually, mould fungi are nothing to cheer about – but now they can be used as “chemical factories”. Scientists at the Vienna University of Technology have succeeded in introducing bacterial genes into the fungus Trichoderma, so that the fungus can now produce important chemicals for the pharmaceutical industry. The raw material used by the fungus is abundant – it is chitin, […]
