Researchers led by Sergey Lobanov from the GFZ German Research Centre for Geosciences have developed a new method to measure the density of silicon dioxide (SiO2) glass, one of the most important materials in industry and geology, at pressures of up to 110 gigapascals, 1.1 million times higher than normal atmospheric pressure. Instead of employing highly focused X-rays at a synchrotron facility, they used a white laser beam and a diamond anvil cell. The researchers report on their new and simple method in the current issue of Physical Review Letters.
