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 ...

MIT researchers found a way to measure cell density quickly and accurately -- measuring up to 30,000 cells in a single hour. They also showed density changes could be used to make useful predictions, ...

More than 2,000 years after Archimedes found a way to determine the density of a king’s crown by measuring its mass in two different fluids, MIT scientists have used the same principle to solve an ...

Measuring density is crucial in manufacturing many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide ...

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 ...
