Researchers use wood materials to create reliable organic solar cells

One of nature’s most common organic materials—lignin—can be used to create stable and environmentally friendly organic solar cells. Researchers at Linköping University and the Royal Institute of Technology (KTH) have now shown that untreated kraft lignin can be used to make solar cells even more environmentally friendly and reliable. The study has been published in the journal Advanced Materials.

New method tracks physical processes inside both liquid and solid parts of Li-ion batteries

What if you could charge your electric vehicle in the same amount of time it takes to fill a tank of gas? In a new paper published in Joule, researchers from McGill University and the University of Quebec in Montreal (UQAM) announced the development of a novel method that enables researchers to peer inside Li-ion batteries and, for the first time, track the physical processes that take place in both the liquid and solid parts of the battery cells as they happen.
