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.

Simulating how the Earth kick-started metabolism

(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living organisms.

Unexpected allies help bacteria clean uranium from groundwater

(Phys.org) —Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. Their initial goal ...

New study explores functionality in aquatic ecosystems

The functions of water-dominated ecosystems can be considerably influenced and changed by hydrological fluctuation. The varying states of redox-active substances are of crucial importance here. Researchers at the University ...

New class of substances for redox reactions

Redox reactions play an important role in our everyday life. In these reactions, one compound releases electrons and is oxidized, while another accepts electrons and is reduced. Such redox reactions are exploited by living ...

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.
