The reduction of iron(III) oxide minerals is an important component of iron cycling in the subsurface. For example, certain bacteria couple carbon oxidation and iron reduction to obtain energy from growth. Although iron oxides are poor conductors of electricity, electrons that are transfered to an iron oxide mineral are quite mobile, using thermal energy to hop from one iron atom to another. New research used time-resolved X-ray absorption spectroscopy to quantify the hopping rates for different iron(III) mineral phases and to confirm a theoretical picture of how the electron at one site alters the positions of the atoms around it. This work contributes to our understanding of how soil mineralogy evolves when geochemical or biochemical processes create reducing conditions.

A Nephila clavipes female spider in the center of her web. The radial strands and scaffolding of her web is composed of major and minor ampullate spider silk fibers. Commonly referred to as dragline silk, this substance was imaged at the nanoscale at Argonne’s Advanced Photon Source. Image by Jeff Yarger.
Untangling the mysteries of spider silk

Argonne chemist Richard Rosenberg examines source material for an experiment to induce chirality into pre-biological systems at the Advanced Photon Source. Rosenberg used X-ray photoelectron spectroscopy to measure the secondary electron induced photolysis reaction rate of a model chiral compound adsorbed on a magnetic substrate. He found that changing the magnetization direction in relation to the high-intensity X-ray beam created an excess of one chirality over another.
