Guided by machine learning, chemists at the Department of Energy’s Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material. A supercapacitor made with the new material could store more energy — improving regenerative brakes, power electronics and auxiliary power supplies. This research has …
UC Berkeley chemists have proved that three carbon structures recently created by scientists in South Korea and Japan are in fact the long-sought schwarzites, which researchers predict will have unique electrical and storage properties like those now being discovered in buckminsterfullerenes (buckyballs or fullerenes for short), nanotubes and graphene. The new structures were built inside …
A Glasgow University team has developed medical sensors powered by a porous foam of graphene and silver, an advance with potential applications in the wearable device market. They used a commercially available graphene foam to make a layered structure with a silver-containing epoxy resin to form supercapacitors capable of storing three times as much power …
