Shrimp shells to produce electrodes for large storage batteries

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.

The climate crisis threatens insects more than previously thought

Until now, insects in the tropics seemed to be the most threatened by climate change by living at the limit of their optimal temperature. An international team of scientists, with Spanish participation, has analysed the existing data and concluded that insects from temperate areas, such as Spain, could be as vulnerable to temperature increases as tropical insects.

Nanoparticles with quantum dots for restoring monuments
SINC

The fluorescence emitted by tiny zinc oxide quantum dots can be used to determine the penetration depth of certain substances used in the restoration of historical buildings. Researchers from Pablo de Olavide University have tested this with samples collected from historical quarries in Cadiz, where the stone was used to build the city hall and cathedral of Seville.
