The complicated evolution of an air film during drop impact. (a) Schematic description of air film evolution; namely, when an air film is entrapped during drop impact on a solid surface, it should evolve into a bubble to minimize its surface energy. (b) Schematic of ultrafast x-ray phase-contrast imaging, which enables the tracking of dynamic changes of air- liquid interfaces in real time. To view a larger version of the image, click on it.
Bubble study could improve industrial splash control

For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects the bubble's fate.

Schematic drawing of the double-stage diamond anvil cell assembly. The typical diameter of nano crystalline diamond semi-balls seen in the center of the drawing is 12-20 micrometers. The starting size of the sample is about three to four micrometers in diameter and about three micrometers thick.

High-pressure science gets super-sized

The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid.

This is an image of a G-protein-coupled receptor signaling complex whose structure was identified in 2011.  The receptor is in magenta while the different G protein subunits are colored green, red and blue.  Stanford biochemist Brian Kobilka shared the 2012 Nobel Prize in Chemistry for his work in determining the structure of this activated GPCR using X-rays provided by Argonne’s Advanced Photon Source.
Advanced Photon Source lights the way to 2012 Chemistry Nobel

Thanks in part to research performed at Argonne National Laboratory, the 2012 Nobel Prize in Chemistry was awarded today to Americans Brian Kobilka and Robert Lefkowitz for their work on G protein-coupled receptors.

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 clearer look at how iron reacts in the environment

Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles.

Tao Sun and Jin Wang, scientists at Argonne National Laboratory, use the Advanced Photon Source to design and test a new technique for X-ray detection that for the first time allows 3-D reconstructions of surface material with high-resolution.
Nano, photonic research gets boost from new 3-D visualization technology

For the first time, X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample.

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

Spiders weave a web even more tangled than originally thought – at least on the nanoscale level, according to a new study performed at Argonne National Laboratory.
