Thermal expansion is critical in many technological applications and its control represents a challenge for the material design. An international team of researchers from China, Italy, United Kingdom and United States has developed a method to control the thermal expansion in framework materials through a redox intercalation process. The study, conducted in part at the XAFS beamline of Elettra, is reported in Nature Communications.
Writing that has lain undiscovered for centuries inside a scroll that was charred in the eruption of Mount Vesuvius in 79 AD has been uncovered for the first time. The text, which was written inside a so called ‘papyrus roll’ that was found in the only surviving ancient library, discovered in Herculaneum 260 years ago, has been examined using X-rays at the European Synchrotron, the ESRF. The result, by a team from the Italian CNR, the ESRF, Ludwig-Maximilian-Universität, and the CNRS, was published in Nature Communications (20 January 2015). It offers new possibilities for deciphering hundreds of so far untouched texts, without the damage that can be caused by trying to open them.
