Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is ...

However, the efficacy of SF6 is entirely dependent on its density. Even a minor leak can compromise insulation, leading to ...

Based on the gas displacement method, this article describes a method for determining the optimal gas type and pressure for measuring cement density, providing a reliable method to characterize porous ...

For the description of ocean currents accurate measurements of the density of sea water are of great importance. For this purpose, measuring instruments are needed which reach a small uncertainty. To ...

This release is also available in German. For oceanography – and there in particular for the description of ocean currents – accurate measurements of the density of sea water are of great importance.
