A diamond anvil cell (DAC) is a high-pressure device used in geology, engineering, and materials science experiments. It enables the compression of a small (sub-millimeter-sized) piece of material to extreme pressures, typically up to around 100–200 gigapascals, although it is possible to achieve pressures … See more The operation of the diamond anvil cell relies on a simple principle: $${\displaystyle p={\frac {F}{A}}}$$ where p is the pressure, F the applied force, and A the area. Typical culet sizes for diamond anvils … See more There are many different DAC designs but all have four main components: Force-generating device Relies on the … See more Prior to the invention of the diamond anvil cell, static high-pressure apparatus required large hydraulic presses which weighed several tons and required large specialized laboratories. The simplicity and compactness of the DAC meant that it could be … See more Heating in diamond-anvil cells is typically done by two means, external or internal heating. External heating is defined as heating the anvils and would include a number of resistive heaters that are placed around the diamonds or around the cell body. The … See more The study of materials at extreme conditions, high pressure and high temperature uses a wide array of techniques to achieve these conditions and probe the … See more The two main pressure scales used in static high-pressure experiments are X-ray diffraction of a material with a known equation of state and measuring the shift in ruby fluorescence lines. The first began with NaCl, for which the compressibility has been … See more An innovative use of the diamond anvil cell is testing the sustainability and durability of life under high pressures, including the search for life on extrasolar planets. Testing portions of … See more WebJan 26, 2024 · Isaac Silvera, Cabot professor of the natural sciences, who has been working on this problem for 45 years, and Ranga Dias, a postdoctoral fellow, reported their results in today’s issue of Science. They began by compressing hydrogen gas (which liquifies when cooled to minus 423 degrees Fahrenheit) in a diamond anvil cell made of two opposing ...
