A team of physicists and geochemists at Argonne and Oak Ridge National Laboratory have shown that instead of just passively observing surface reactions of minerals, they can use X-rays to create the conditions by which reactions happen while simultaneously observing them.

The rise of X-ray beam chemistry

By using powerful photon beams generated by the Advanced Photon Source, a DOE User Facility, researchers have shown that they can now control the chemical environment and provide nanoscale structural detail while simultaneously imaging the mineral calcite as it is pushed to its extremes.

Argonne Mechanical Engineer Wenhua Yu installs a cylinder of high-conductivity foam into a prototype container as former postdoctoral fellow Taeil Kim, makes adjustments to a heat transfer loop in the background. Argonne researchers received funding from the U.S. Department of Energy SunShot Initiative to scale up and demonstrate their novel thermal energy storage system, which efficiently stores solar energy as heat for later use generating electricity. Total project funding is $1.6 million and includes an industry cost sharing arrangement. (Click image for larger view).
SunShot Initiative award funds scaleup of Argonne’s leading-edge thermal energy storage system

On September 16, 2015, the U.S. Department of Energy SunShot Initiative program announced funding awards to several research projects that aim to make concentrating solar power (CSP) plants cost competitive with traditional forms of electricity.

Team announces breakthrough observation of Mott transition in a superconductor

An international team of researchers announced today in Science the observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition.

A schematic of the pressure chamber of the double-stage diamond anvil cell (dsDAC) for ultra-high pressure generation and a photo of a DAC produced at BGI. Semi-balls made of nanocrystalline diamond of extraordinary strength are attached to the culets of the opposed gem quality diamonds of the DAC. A sample of osmium, shown as a small red dot on the top of the lower semi-ball, has a size of ca. 3 microns. It is compressed between the tips of the semi-balls, which are supported by a pressure-medium (solidified inert gases or paraffin) filling the pressure chamber of the DAC. Ultra-high pressure  is generated on the sample due to the two-stage exertion of a big force on a very small area. The diameter of the semi-balls is about 10 microns. The diameter of culets of the diamonds, to which the semi-balls are attached, is 250 microns. Image courtesy Elena Bykova,  University of Bayreuth. (Click to view larger.)
Extreme pressure causes osmium to change state of matter

An international group of researchers have demonstrated that ultra-high pressures cause core electrons to interplay, which results in experimentally observed anomalies in the compression behavior of the material.

Fertilization discovery: Do sperm carry tiny harpoons?

Could the sperm harpoon the egg to facilitate fertilization? That’s the intriguing possibility raised by the University of Virginia School of Medicine’s discovery, using the Structural Biology Center at the Advanced Photon Source, that a protein within the head of the sperm forms spiky filaments, suggesting that these tiny filaments may lash together the sperm and its target.

Making fuel from light: Argonne research sheds light on photosynthesis and creation of solar fuel

Recent experiments at Argonne have afforded researchers a greater understanding of how to manipulate photosynthesis, putting humankind one step closer to harvesting “solar fuel,” a clean energy source that could one day help replace coal and natural gas.

Scientists at Argonne National Lab have developed a new fuel cell catalyst using earthly abundant materials with performance that is comparable to platinum in laboratory tests. If commercially viable, the new catalyst could replace platinum in electric cars powered by fuel cells instead of batteries, which would greatly extend the range of electric vehicles and eliminate the need for recharging. This figure shows the microstructural difference between conventional catalysts and the new reduced-platinum catalyst. (Image courtesy Di-Jia Liu; click to view larger).
New catalyst may hasten commercialization of fuel cell vehicles

Supported by DOE’s Fuel Cell Technologies Office, scientists at Argonne have developed a new fuel cell catalyst using earthly abundant materials with performance that is comparable to platinum in laboratory tests. If commercially viable, the new catalyst could replace platinum in electric cars powered by fuel cells instead of batteries, which would greatly extend the range of electric vehicles and eliminate the need for recharging.
