Spinels are oxides with chemical formulas of the type AB2O4, where A is a divalent metal cation (positive ion), B is a trivalent metal cation, and O is oxygen. Spinels are valued for their beauty, which derives from the molecules’ spatial configurations, but spinels in which the trivalent cation B consists of the element chrome (Cr) are interesting for a reason that has nothing to do with aesthetics: They have magnetic properties with an abundance of potential technological applications.

Artwork does not last forever. This is particularly true for paintings, which are appreciated for their visual appearance, but inevitably deteriorate through physical processes such as the deposition of air-borne dust and soot, oxidation, and attack by free radicals. As a result, after 50 to 100 years, a once-colourful painting that was exposed to city air may have become uniformly brown, or black, or white, and its protective varnish may have become opaque, cracked and irregular.

The process engineering has thus gained a method of testing theoretical models in practice.

Solar hydrogen can be produced from water and light in a process called photocatalytic water-splitting and could help to mitigate the impact of climate change, as no fossil fuels are used in its production. It then can be used as a renewable, environmentally friendly energy carrier, such as in hydrogen fuel cells. Nonetheless, it has proved a major scientific challenge to scale-up photocatalytic water-splitting to a stage where it could viably be used to produce hydrogen in enough quantities to revolutionise clean energy.

And, because neutrons and x-rays complement each other, neutrons are a valuable tool for verifying the results obtained via x-ray scattering at Argonne.
"Lithium has a large absorption coefficient for neutrons, which means that neutrons passing through a material are highly sensitive to its lithium concentrations," said Ziyang Nie, lead author and graduate student in Koenig's group. "We demonstrated we could use neutron radiographs to track in situ lithiation in thin and thick metal oxide cathodes inside battery cells. Because neutrons are highly penetrating, we did not have to build custom cells for the analysis and were able to track the lithium across the entire active region containing both electrodes and electrolyte."
Exactly how that process works at the microscopic level is not well understood.
Answering this question could have a big impact on both plant ecology and agriculture, which is why professors Kathryn and Jonathan Morris from Xavier University are using neutron scattering at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) to observe firsthand how these info-chemicals travel along tiny, pipe-like networks called fungal hyphae. Whether the messages move passively along the outside of those fungal networks or the fungi deliberately locate and absorb info-chemicals for transportation remains unclear.

Precise measurements at the ILL of beta asymmetry rule out neutron decay into exotic dark matter particles.
Last year, scientists became rather excited when they thought they might have found evidence for the production of dark matter particles from experiments measuring the lifetime of the neutron – one of the two constituents of the atomic nucleus (the other is the proton). The neutron is generally stable when bound in atomic nuclei, but in the free state it lasts for just under 15 minutes. Two different kinds of neutron experiments had come up with considerably different lifetimes, and researchers thought that the anomaly might be due to the decay to a dark matter particle contributing to one type of experiment but not to the other.
For the past 25 years, scientists have been developing fluorescent proteins for bioimaging. Today their diversity covers nearly the whole visible spectrum, including blue, cyan, green, yellow, orange, red, far-red and near infrared, allowing scientists to produce detailed images of various proteins’ localization within live cells using multicolour labelling.
A team of researchers at Institut Laue–Langevin (ILL) have used neutron scattering experiments to study a family of fluorescent proteins called Cyan Fluorescent Proteins (CFPs). “CFPs are very useful tools for bioimaging as they can be used to produce pictures of live cells - if the CFP is used as a fusion protein, it can reveal information about protein location, and if used as part of a biosensor, it can report on the evolution of various cell parameters (pH, calcium concentration…)” says Dr Judith Peters, scientist at ILL and professor at Université Grenoble Alpes.

Jülich, 26 October 2016 - An international research team has proved the existence of spin-spirals in a quantum liquid.

About the British physicist Peter Higgs has been much talk recently. Researchers at the European Nuclear Research Center CERN in Geneva were more likely to prove what he predicted in the 1960s as a Higgs boson.

During the cooling of a so called "quantum spin ice" state, they observed for the first time evidence of a spontaneous exchange with what Peter Higgs had predicted as a Higgs field in a magnet. The results are published in "Nature Communications".
