Using the stimulant as a catalyst, researchers create new gels for drug delivery. Caffeine is well-known for its ability to help people stay alert, but a team of researchers at MIT and Brigham and Women’s […]

Researchers at MIT have found a way to make graphene with fewer wrinkles, and to iron out the wrinkles that do appear. They found each wafer exhibited uniform performance, meaning that electrons flowed freely across each wafer, at similar speeds, even across previously wrinkled regions.
