Predicting X-ray absorption spectra from graphs

X-ray absorption spectroscopy (XAS) is a popular characterization technique for probing the local atomic structure and electronic properties of materials and molecules. Because atoms of each element absorb X-rays at characteristic ...

Researchers find new shape for hydrophobic molecules in water

The embedding of hydrophobic molecules in water looks quite different than previously assumed. In water, hydrophobic molecules are surrounded by a two different water populations: the inner shell forms a two-dimensional network ...

New tool to measure aerosol optical hygroscopicity

Researchers at Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science recently developed a humidified cavity-enhanced albedometer (H-CEA) which could simultaneously measure relative-humidity-dependent ...

First detailed electronic study of new nickelate superconductor

The discovery last year of the first nickel oxide material that shows clear signs of superconductivity set off a race by scientists around the world to find out more. The crystal structure of the material is similar to copper ...

Shocking heat waves stabilize single atoms

Single atoms work great as catalysts, but they usually don't stay single for long. Argonne scientists are part of a team that uses high-temperature shock waves to keep them in their place.

New approach facilitates spectroscopy on individual molecules

While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich (TUM) provides precise information about the interaction of individual ...

A water-splitting catalyst unlike any other

Electricity can be generated by renewable sources such as sunlight and wind, then used to split water, which makes hydrogen as a fuel for emerging energy devices such as fuel cells. Because hydrogen is a clean fuel, researchers ...
