“…High-pressure experiments were carried out using a cubic anvil press (180 ton, CT-factory, Tokyo, Japan) calibrated with phase transitions of bismuth [ 33 ]. The Cu-BTC powder was encapsulated in a cylindrical copper capsule, which was embedded in a NaCl filler and then a graphite tube heater, which were then placed in a 13 mm pyrophyllite cube with stainless steel electrodes.…”

Ultrahigh-Pressure Preparation and Catalytic Activity of MOF-Derived Cu Nanoparticles

A metal–organic framework (MOF) consisting of Cu-benzenetricarboxylic acid was processed under ultrahigh pressure (5 GPa) and at temperature of up to 500 °C. The products were characterized with TEM, FTIR, and XAFS. The decomposition of the MOF started at 200 °C at 5 GPa. This temperature was much lower than that in the vacuum. Single-nanometer Cu nanoparticles were obtained in carbon matrix, which was significantly smaller than the Cu particles prepared at ambient pressure. The catalytic activity for Huisgen cycloaddition was examined, and the sample processed at 5 GPa showed a much improved performance compared with that of the MOF-derived Cu nanoparticles prepared without high pressure.

“…The apparatus has undergone a detailed and adequate pressure calibration procedure with an error of less than 0.3 GPa. The pressure calibrations for the apparatus at room temperature were performed according to the phase transitions of Bi (I‐II at 2.55 GPa, II‐III at 2.77 GPa, and III‐V at 7.7 GPa) (Knibbe et al., 2018) and ZnTe (I‐I′ at 6.6 GPa, I′‐II at 8.9 GPa, and II‐III at 12.1 GPa) (Endo et al., 1982), with uncertainties of less than 0.3 GPa. The pressure calibrations at high temperature (1473 K) were based on phase transitions of coesite‐stishovite at 9.2 GPa (Zhang et al., 1996) and Mg 2 SiO 4 olivine‐wadsleyite at 13.6 GPa (Katsura et al., 2004).…”

Talc is widely distributed in metamorphic and hydrothermally altered rocks, and its velocity is useful for constraining the velocity of mantle wedge. In this study, we used ultrasonic interferometry to study the elastic properties of talc polycrystalline samples at high pressure (up to 5.6 GPa). VP increases monotonically with increasing pressure, and VS increases with pressure up to ∼3.2 GPa, but negative pressure dependence occurs above ∼3.2 GPa. Talc has a VP/VS ratio of 1.63–2.14 and Poisson's ratio of 0.20–0.36 at the pressure of 1.2–5.6 GPa, which can be used to explain some anomalous seismic observations in subduction zone. Combining the elastic properties of talc with those of olivine, orthopyroxene, and antigorite, the wave velocity of mantle wedge was calculated as a function of water content. The results suggest that lower water content is needed to match the observed values of seismic tomography when talc is present, compared with the antigorite scenario.

“…The Bi II-III and III-V phase transitions are sluggish in solid pressure media, and thus, the minimum in the electrical resistance labeled as "II-III" in Figure 2 was typically placed at 3.1 GPa for the pressure calibration of multi-anvil assemblies [19,20]. The Bi III-V phase transition at 7.7 GPa was indicated by the start of electrical resistivity reduction [17]. For pressure calibrations at high temperatures using 18 mm octahedra with gaskets cast from 646 ceramic, quench experiments were performed on amorphous or crystalline SiO2 powders [18] near the pressure-temperature conditions appropriate to the quartz-coesite phase transition (see Figure 3 for the cross section of the high-temperature assembly).…”

“…The new approach presented here can easily be adopted to any MAP laboratory. Our "injection-molded" octahedra were tested in our mineral physics laboratory at the University of Hawaii at Manoa, using both 1000-ton and 2000-ton presses equipped with Walker-design multi-anvil devices through a series of pressure-calibration experiments based upon the room temperature, pressure-dependent phase transitions in bismuth (Bi) [17], and the high-temperature phase transition in SiO 2 from quartz to coesite [18]. We then compare the pressure-generating efficiency and thermal-insulating properties of our cast ceramic octahedra to the calibrations for the corresponding 14/8 and 10/5 COMPRES cell assemblies (where the first number refers to the octahedron's OEL and the second number refers to the cube's TEL).…”

Making consistent and precise octahedral pressure media is crucial for reproducible high-pressure experiments in the multi-anvil press. Here we report a new approach of casting octahedra using 3D-printed molds, and pressure calibrations for octahedra both with and without pre-existing gaskets (“fins”). The 3D-printed molds for casting octahedra from either Ceramacast 584-OF or 646 cement improve the reproducibility of the octahedra and allow for a pre-existing central hole (for the high-pressure cell assembly) in the final cast product. Pressure and temperature calibrations of the octahedra have been performed based on phase transitions in bismuth (Bi) and silica (SiO2), respectively, in order to determine the efficiency and reproducibility of pressure generation and thermal insulation for cast octahedra designed for use with 18/12, 14/8, and 10/5 multi-anvil assemblies. The pressure-generating efficiency of the 14/8 and 10/5 octahedra with pre-existing gaskets, cast from the 584-OF cement, is similar to that of the corresponding COMPRES (Consortium for Materials Properties Research in Earth Sciences) octahedra, and more efficient than pre-cast octahedra made from the same material but lacking pre-existing gaskets. The efficiency of pre-gasketed 18/12 octahedra made of the 646 cement is markedly lower than those of the 584 cement. However, the 18/12 large-volume octahedra, cast (with fins) from the ZrO2-based 646 cement, also provides efficient thermal insulation. Casting octahedral solid pressure media for multi-anvil experiments using 3D-printed “injection” molds is a low-cost and low failure-rate alternative for conducting reproducible experiments at high pressure in the multi-anvil apparatus.
