The existence of the protonated hexatitanate H2Ti6O13 was only very recently demonstrated, even though only a partial characterisation has been accomplished. Our analysis of data from synchrotron and neutron powder diffraction, combined with IR spectroscopy data, provided us with a precise determination of the crystal structure, thus shedding light on the electrochemical properties of the material and the charge and discharge processes. H2Ti6O13 finally revealed itself to be an interesting material for rechargeable lithium batteries.
Selenium (Se) is an essential micronutrient for human health, protecting, for example, against cardiovascular disease, male sterility and certain forms of cancer. Even though it is a common nutrient e.g. in cereals, it is lacking in the diet of at least 1 billion people around the globe. The few available data indicate that Portugal is one of the countries concerned. A research project taking place in Portugal aims to assess the levels of Se in the country’s cereals and soils.
Scientists working at the Institut Laue-Langevin have shown that the charge of gold nanoparticles, identified by major pharmaceutical companies as a drug delivery agent of the future for the treatment of cancer, affects how they interact with our cell’s protective outer wall.

Since the period that followed World War II, gas turbines have developed to become more efficient, which led to increased gas temperatures inside the turbines. It is estimated that future gas turbines will function at temperatures about 200°C higher than today. The materials currently used cannot withstand such high temperatures. For this reason it is necessary to investigate new materials.

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. His proposed Higgs mechanism explains how elementary particles get their mass – and also plays a role beyond elementary particle physics. By using neutron scattering experiments, an international research team found the first indication that this mechanism can explain a phase transition of exotic magnetic states in a Yb2Ti2O7 crystal near absolute zero. 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”.
