Customer Success Story: Pioneering High-Pressure Research with Almax easyLab’s Diamond Anvils

We are thrilled to share a remarkable study conducted by one of our customers, which highlights the advanced capabilities of Almax EasyLab’s diamond anvils in high-pressure research. The study focuses on an updated isothermal equation of state (EoS) for molybdenum (Mo), achieved through innovative compression techniques using our beveled and toroidal diamond-anvils (DACs).

In a groundbreaking experiment, the research team developed a copper (Cu) pressure-transmitting medium (PTM) for the toroidal DACs, which provided a superior compression environment. This innovative approach allowed the team to achieve Mo unit-cell volumes up to 336 GPa, a significant improvement compared to traditional methods using a neon (Ne) PTM. The study demonstrated that using a softer metal like Cu in toroidal DACs can enhance the accuracy of high-pressure measurements, yielding results comparable to those obtained with noble-gas media under multi-megabar conditions.

The research, conducted at renowned facilities including Argonne National Lab and PETRA-III, involved meticulous sample preparation using focused-ion beam (FIB) technology to mill toroidal profiles from Type IIa beveled anvils supplied by Almax EasyLab. The Mo samples, encased in Cu, were subjected to extreme pressures, and the results were closely monitored using state-of-the-art x-ray diffraction techniques.

This study not only provides a new EoS for Mo but also sets a benchmark for future high-pressure research. The findings underscore the critical role of Almax EasyLab’s diamond anvils in pushing the boundaries of material science.

We are proud to support pioneering research like this and look forward to seeing more breakthroughs achieved with our high-precision instruments.
