Purple power: Synthetic ‘purple membranes’ transform sunlight to hydrogen fuel

Argonne researchers have found a new way to produce solar fuels by developing “synthetic purple membranes.” These membranes involve an assembly of lipid nanodiscs, man-made proteins, and semiconducting nanoparticles that, when taken together, can transform sunlight into hydrogen fuel.

“When scientists add or remove a proton (H+) from the perovskite (SmNiO3 (SNO)) lattice, the material’s atomic structure expands or contracts dramatically to accommodate it in a process called ‘lattice breathing,’” said Badri Narayanan, an Argonne assistant material scientist and co-author of the study. But when it happens repeatedly, this activity wanes, resembling human forgetfulness. (Image by Argonne National Laboratory.)
Forget about it

Inspired by human forgetfulness — how our brains discard unnecessary data to make room for new information — scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually “forgets.” This could one day be used for advanced bio-inspired computing.

Matt Dietrich is a physicist in Argonne’s Physics Division. His research into new physics beyond the Standard Model, which could provide clues as to why matter dominates our universe, earned him a 2017 DOE Early Career Research award. (Image courtesy of Matt Dietrich.)
Two Argonne scientists receive DOE Early Career Research Program awards

Argonne scientists Matt Dietrich and Tom Peterka have received DOE Early Career Research Program awards. Peterka was awarded for his work to redefine scientific data models to be communicated, stored and analyzed more efficiently. Dietrich was recognized for his work probing potential new physics beyond the Standard Model that could help explain why matter came to dominate the universe.

Mica provides clue to how water transports minerals

In a new study from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with the University of Illinois at Chicago and the University of Delaware, chemists have been able to look at the interface between water and muscovite mica, a flat mineral commonly found in granite, soils and many sediments. In particular, the researchers looked at the capture and release of rubidium – a metal closely related to but more easily singled out than common elements like potassium and sodium.
