Spanish researchers at MIT have developed a system to produce electrodes for vanadium flow batteries, used in renewable energy storage. The electrodes are made from chitin, a polysaccharide found in the exoskeleton of crustaceans and insects. The advantage of this component is that it contains nitrogen in addition to carbon, which is then incorporated into the structure of the electron during the production process, improving electrode’s performance.
French scientists at the Neel Institute have produced a graphene patch that records the condition of chronic wounds, such as ulcers suffered by the elderly or those with diabetes, at any time. The data can be sent from home to the hospital via mobile phone, facilitating a rapid response to possible infections.
