Scientists from Universidad Carlos III in Madrid (UC3M) are participating in a European research project that involves developing a new type of tidal energy generator that will be cheaper and more efficient. The device would replace conventional magnetic materials for new materials that are made using an alternative technology.
US and Spanish researchers have used a polymeric material to replicate the body of the Agrilus planipennis, a beetle that invades woods in North America. The decoy reproduces the texture and iridescent green colour of the females’ shell on a nanometric scale, and does so with such perfection that the males pounce on them as if they were real. In this way they can be caught and populations of this pest reduced.
