  • A novel chitosan/sponge chitin origin material as a membrane for supercapacitors

    A new chitosan/sponge chitin – based membrane (CS/CH membrane) was prepared via the casting method for the first time. We used the demineralized skeleton of the marine demosponge Ianthella basta as a source for a chitinous network. The obtained membrane was immersed in 1 M LiOAc (lithium acetate) solution and tested in an Electric Double Layer Capacitor (EDLC) cell. For comparison, chitosan (CS) with […]

  • Biomass-Based Solar Cells from Shrimp

    Using hydrothermal carbonization, researchers at Queen Mary University of London’s (QMUL) School of Engineering and Materials Science in the UK have exacted carbon nanodots from shrimp cells and applied them to zinc-oxide nanorods to make biomass-based solar cells. More info

  • Mantis shrimp inspires new body armor

    The mantis shrimp is able to repeatedly pummel the shells of prey using a hammer-like appendage that can withstand rapid-fire blows by neutralizing certain frequencies of “shear waves,” according to new research by Univ. of California, Riverside and Purdue Univ. engineers. The club is made of a composite material containing fibers of chitin, the same substance found in many marine […]

  • Shrimp Shells Yield Cheap Solar Cells

    Electricity-generating solar cells have been created from the chemicals found shells of shrimp and other crustaceans, for the first time. The materials chitin and chitosan, found in the shells, are abundant and significantly cheaper to produce than the expensive metals such as ruthenium, which is similar to platinum, that are currently used in making nanostructured solar-cells. Currently the efficiency of […]

  • Lobster industry byproducts make tasty treats

    In a bid to reduce waste from the harvest and export of southern rock lobsters – a multimillion dollar industry in South Australia – Flinders University and the South Australian Research and Development Institute (SARDI) have teamed up to find innovative ways of using leftover shells and parts from the processing of this premium seafood. The two institutes are working […]

  • A Sea Change in IBD Treatment?

    A Florida immunologist and macrophage biologist recently received a substantial grant from the National Institutes of Health to investigate a possible role for chitin, an abundant component of shrimp, crab and lobster shells, in treating inflammatory bowel disease. Yoshimi Shibata, PhD, professor of biomedical science at the Charles E. Schmidt College of Medicine of Florida Atlantic University, in Boca Raton, […]

  • Researchers hope to turn shrimp shells into useful products

    University of Alabama chemist Robin Rogers imagines a future where shrimp shells could become more than a smelly seafood byproduct. “I believe in what I would call a chitin economy. I personally believe, if properly developed, the material you can develop from chitin and the markets you could sell them in would make the shrimp shell worth more than the […]

  • Shrimp, 30,000 Volts Help Start-up Land $1.5 Million for Uranium Extraction

    The U.S. Department of Energy selected a University of Alabama start-up company for an approximate $1.5 million award to refine an alternative material to potentially extract uranium from the ocean. Uranium, which naturally occurs in seawater and in the Earth’s crust, is the fuel for nuclear power. For decades, scientists have sought a more economical and efficient way to remove […]

  • Australia: A new project aims to convert garbage — including fish byproducts — into valuable products

    One company’s food waste could be transformed into another’s treasure – or even a product that improves our health and wellbeing. This is the premise of research at the University of Sydney that’s investigating how discarded food can be rich in nutrients. Professor Fariba Dehghani, of the university’s school of chemical and biomolecular engineering, is leading the ongoing project and […]
