As the consumer electronics industry continues to grow, there is also a growing demand for the raw materials and metals used to make electronic components. Scientists at Osaka University have discovered a sustainable alternative to these finite resources in an unexpected place – crab shells. 

The researchers have developed a nanocarbon material for electronics applications made from chitin, one of the most important biopolymers in nature that is found abundantly in crab shells. 

According to the experts, nanocarbon materials show significant promise for use in electronic devices. Those with porous three-dimensional (3D) structures provide efficient networks for the transport of charge as well as electrolytes and reactants. 

Energy flow through nanocarbon materials can be made even more efficient with the addition of imperfections – known as defects – in the form of nitrogen and other chemical elements. (Read more)
