Laser heating with doughnut-shaped beams.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 12/28/2022, Vol. 132 Issue 24, p1-9. 9p.

Abstract: Doughnut-shaped laser beams have applications in laser-based additive manufacturing, laser heating of diamond anvil cells, and optical super-resolution microscopy. In applications like additive manufacturing and heating of diamond anvil cells, a doughn...

Yield strength of CeO2 measured from static compression in a radial diamond anvil cell.

Publication Type: Academic Journal

Pressure evolution in a diamond anvil cell without a pressure medium.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 3/28/2022, Vol. 131 Issue 12, p1-9. 9p.

Abstract: The inhomogeneity in pressure inside the sample chamber of a diamond anvil cell (DAC) poses a major challenge to the accurate measurement of the properties of materials under high pressures, especially when the pressure medium solidifies under compress...

Strength of tantalum to 276 GPa determined by two x-ray diffraction techniques using diamond anvil cells.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 1/7/2022, Vol. 131 Issue 1, p1-7. 7p.

Abstract: Tantalum (Ta) is a metal that has useful properties that make it useful in extreme environments. It is, therefore, important to understand how Ta performs in such extreme conditions by accurately measuring its properties. In this work, the yield streng...

High‐pressure Raman study of Na‐Ca burbankite—A possible CO2 host in deep mantle.

Publication Type: Academic Journal

Source(s): Journal of Raman Spectroscopy. Jan2023, Vol. 54 Issue 1, p101-106. 6p.

Abstract: Na‐Ca carbonates synthesized in high‐pressure experiments and found in mineral inclusions inside diamonds, exhumed from mantle depths, attract a lot of attention as potential hosts of subducted CO2 in the deep mantle and sources of carbonate‐rich magma...

Pressure-dependent bandgap study of MBE grown {CdO/MgO} short period SLs using diamond anvil cell.

Publication Type: Academic Journal

Source(s): Applied Physics Letters. 12/12/2022, Vol. 121 Issue 24, p1-6. 6p.

Abstract: Semiconductor superlattices (SLs) have found widespread applications in electronic industries. In this work, a short-period SL structure composed of CdO and MgO layers was grown using a plasma-assisted molecular beam epitaxy technique. The optical prop...

Synthesis and Magnetic Properties of Iron Polyhydrides at Megabar Pressures.

Publication Type: Academic Journal

Source(s): JETP Letters. Dec2022, Vol. 116 Issue 11, p804-816. 13p.

Abstract: Iron polyhydrides have been synthesized at pressures of 77–157 GPa and temperatures up to 2000 K by the laser heating of an iron–borazane (ammonia borane NH3BH3) sample in diamond anvil cells. X-ray spectra of the synthesized products indicate the form...

SrB4O7:Sm2+ fluorescence improves the accuracy of temperature measurements in externally heated diamond anvil cells.

Publication Type: Academic Journal

Source(s): Review of Scientific Instruments. 12/1/2022, Vol. 93 Issue 12, p1-8. 8p.

Abstract: The sample temperature in an externally heated diamond anvil cell (EHDAC) is generally measured by a thermocouple fixed to the pavilions of diamond anvils, ignoring the temperature difference between the thermocouple and the sample. However, the measur...

Probing the partitioning behaviour of Xe using in situ X-ray synchrotron techniques at high P–T conditions.

Publication Type: Academic Journal

Source(s): High Pressure Research. Dec2022, Vol. 42 Issue 4, p318-335. 18p.

Abstract: Understanding crystal/melt xenon (Xe) partitioning at depth is key to properly trace planetary processes using Xe isotopes. Partition coefficients measured on experimental samples recovered at room pressure (P) and temperature (T) span 6 orders of magn...
