easyLab® Mcell Ultra used to study topological semimetal LaBi

Researchers use the easyLab® Mcell Ultra to investigate the possible relation between extreme magnetoresistance (XMR) and superconductivity by looking at pressure effects on LaBi.  With increasing pressure Tafti et al. observe the disappearance of the XMR followed by the appearance of superconductivity at about 3.5 GPa.   In contrast to other topological semimetals, LaBi appears to show a region of coexistence between XMR an ...read more

New miniature Boehler-Almax anvils with less 0.5mm thickness considerably reduces attenuation in X-Ray Raman scattering experiments

In an recent article [c.f. Petitgirard et al., J.Synchrotron Rad. 24, 276-282 (2017)], Petitgirard and co-workers describe their development of miniature Boehler-Almax design anvils for X-ray Raman scattering (XRS) experiments.   These miniature anvils manufactured by Almax easyLab, have thickness of less than 0.5mm, which is about one third of the size of typical diamond anvils.  Based on such miniature diamond anvils the resea ...read more

Discovery of new material state counterintuitive to laws of physics

When you squeeze something, it gets smaller. Unless you’re at Argonne National Laboratory. At the suburban Chicago laboratory, a group of scientists has seemingly defied the laws of physics and found a way to apply pressure to make a material expand instead of compress/contract. “It’s like squeezing a stone and forming a giant sponge,” said Karena Chapman, a chemist at the U.S. Department of Energy labor ...read more

Type IIa Diamond Anvil FTIR Selection

Diamonds are categorized by the presence of nitrogen in their crystal structure. Type I diamonds have nitrogen and are the most common diamonds, whereas type II diamonds have no detectable nitrogen in their crystal structure. Type I diamonds are further classified according to the aggregation state of the nitrogen in the crystal structure. Thus, type Ia diamonds are natural diamonds with aggregated nitrogen. Type Ib diamonds, on the other hand ...read more

Extra facets on diamond anvils can occur

When polishing natural diamond anvils, we are sometimes confronted with minor naturals or naives around the girdle of the diamond anvil during the finish polishing step. In order to clean the natural surfaces from any such defects, we must polish a small extra facet on these naturals or naives. This additional facet can be at most up to 1/3 of the pavilion or crown facet size. Furthermore, this facet does not weaken the diamond anvil. You ...read more

An Introduction to Diamond Anvil High Pressure Cells

To generate high pressures large forces are needed. Since pressure = force/area, it follows that for a given force, the smaller the area over which it is applied the greater will be the pressure. The simplest way to generate a high pressure on a sample is to trap it between two opposed pistons (or anvils) that are then driven together along a common axis. More complex systems are sometimes used. Specifically, four pistons applied along th ...read more

Synthetic Type 2a Anvils with Ultra-Low Fluorescence Available from easyLab

 Natural diamond crystals have been used for DAC anvils for many years now.  Although widely successful, natural anvils suffer from a limited lifetime, stability and attainable pressures because of the crystal defects inherent to them as well as quality variations.  Furthermore, natural diamond crystals emit luminescence, which may make it difficult to measure the optical signal from a sample placed inside the DAC. ...read more
