Argonne materials scientists announced a new technique to grow these little forests at the microscale (the scale shows 100 micrometers, which is about the diameter of a single human hair). Image by Arnaud Demortière, Alexey Snezhko and Igor Aronson. Click to enlarge.
Good hair day: New technique grows tiny 'hairy' materials at the microscale

Scientists at Argonne attacked a tangled problem by developing a new technique to grow tiny “hairy” materials that assemble themselves at the microscale.

Most simple solar cells handle the bluish hues of the electromagnetic spectrum inefficiently. This is because blue photons — incoming particles of light that strike the solar cell — actually have excess energy that a conventional solar cell can’t capture. Click to enlarge.
New solar cell technology captures high-energy photons more efficiently

Scientists at Argonne and the University of Texas at Austin have together developed a new, inexpensive material that has the potential to capture and convert solar energy — particularly from the bluer part of the spectrum — much more efficiently than ever before.

Currently, the most efficient methods we have for making fuel – principally, hydrogen – from sunlight and water involve rare and expensive metal catalysts, such as platinum. Click to enlarge.
Cobalt catalysts allow researchers to duplicate the complicated steps of photosynthesis

In a new study, Argonne researchers have used cobalt catalysts to duplicate the steps in the complicated electronic dance of photosynthesis.

Argonne scientists Rajh, Soderholm and Segre named AAAS fellows

Physical chemist Tijana Rajh, chemist Lynda Soderholm and physicist Carlo Segre of the U.S. Department of Energy’s Argonne National Laboratory have been named fellows of the American Association for the Advancement of Science.

In order to understand how complex materials merge at the boundary, scientists look at cross-sections of an oxide superlattices. In this picture, peaks correspond to layers of cuprate superconductor and valleys to metallic manganites (bottom region). The power of scanning tunneling microscopy allows researchers to gain insight into both the material's topography as well as its electronic properties. Click to enlarge.
A material's multiple personalities

Just like people, materials can sometimes exhibit “multiple personalities.” This kind of unusual behavior in a certain class of materials has compelled researchers at the U.S. Department of Energy’s Argonne National Laboratory to take a closer look at the precise mechanisms that govern the relationships between superconductivity and magnetism.

Microorganisms found in salt flats could offer new path to green hydrogen fuel

A protein found in the membranes of ancient microorganisms that live in desert salt flats could offer a new way of using sunlight to generate environmentally friendly hydrogen fuel, according to a new study by researchers at the U.S. Department of Energy’s Argonne National Laboratory.
