Novel approach improves graphene-based supercapacitors

Demand for integrated energy storage devices is growing rapidly as people rely more and more on portable and wireless electronics, and the global need grows for clean energy sources such as solar and wind energies.

Tiny pump builds polyrotaxanes with precision

Northwestern University researchers have developed the most precise way to build polyrotaxanes, a mechanically locked polymer for slide-ring gels, battery electrode materials and drug-delivery platforms.

How to free trapped radicals from carboxyl

The removal of carboxyl groups and the release of alkyl radical fragments from the tight binding of carboxyl groups are promising directions in organic synthesis, especially in drug synthesis. Various catalysts have been ...
