Berger et al. utilize extreme ultraviolet, second-harmonic generation (XUV-SHG) spectroscopy to investigate the polar metal phase of lithium osmate (LiOsO3), where the coexistence of polarity and metallicity is unexpected. As the first demonstration of XUV-SHG spectroscopy around a phase transition, these results pave the way for using nonlinear XUV methods to investigate broken symmetry from an element-specific perspective.

Molecular Complex Removes Copper Ions from Water
X-ray analyses provided key insights into the copper uptake mechanisms in a new organic-inorganic hybrid material that quickly and selectively removes copper ions from water. The material provides an efficient tool for copper remediation as well as a blueprint for creating other hybrid materials for removing toxic metals from water. Read more »
Scientists Design New Framework for Clean Water
A promising solution to water pollution from abandoned copper mines relies on materials that adsorb copper ions from wastewater, but commercially available products lack the required chemical specificity and load capacity. A team of scientists has designed a new crystalline material that targets and traps copper ions from wastewater with unprecedented precision and speed. Read more »
Scientists Trace ‘Poisoning’ in Chemical Reactions to the Atomic Scale
A team of researchers has employed a combination of measurements, including x-ray experiments at the ALS, to gather the most detailed information yet on problematic carbon-based deposits called “coke,” and to find ways to prevent its formation or reduce its effects. Read more »
On the Way to Unlimited Energy
With the help of four different ALS beamlines, scientists were able to understand and improve the morphology of the main device structure in organic photovoltaic cells. Read more »
