Here's a unique "sponge" that turns used cooking oil into cheap biodiesel
This sponge-like creation is a new type of ultra-efficient catalyst for changing molecules into raw materials, i.e. materials intended for further processing. According to its authors, it is one of a kind, as it allows a number of different chemical reactions to be carried out within one material, with a high degree of control over the results. 'Previously manufactured catalysts can perform multiple reactions simultaneously, but we have seen many times that this approach has little chemical control, making it inefficient and difficult to predict. Our bio approach leans towards nature's catalysts - enzymes - to develop a powerful and precise way to perform many reactions in a specific order. It's like having a production line for nano-scale chemical reactions - all in one miniature and super-efficient catalyst molecule, explains Professor Karen Wilson, co-author of the study.
