Adaptation of the Bridgman anvil cell to liquid pressure mediums [PDF]

open access: yesRev. Sci. Instrum. 78, 123901 (2007), 2008
The advantage of Bridgman anvil pressure cells is their wide pressure range and the large number of wires which can be introduced into the pressure chamber. In these pressure cells soft solid pressure mediums like steatite are used. We have succeeded in adapting the Bridgman cell to liquid pressure mediums.

Effect of Oxygen Mole Fraction on Static Properties of Pressure-Sensitive Paint [PDF]

open access: yesSensors, Vol. 21, No. 4, 1062 (2021), 2020
The effects of oxygen mole fraction on the static properties of pressure-sensitive paint (PSP) were investigated. Sample coupon tests using a calibration chamber were conducted for polymer-based PSP (PHFIPM-PSP), polymer/ceramic PSP (PC-PSP), and anodized-aluminium PSP (AA-PSP).

Pressure-Induced Polymerization: Addition and Condensation Reactions

open access: yesMolecules, 2021
Under pressure of 1–100 GPa, unsaturated organic molecules tend to form covalent bond to each other for a negative enthalpy change, which often produces polymeric materials with extended carbon skeleton.

Anisotropy of structural and mechanical properties in CuCrZr alloy following hydrostatic extrusion process [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2022
The methods of severe plastic deformation (SPD) of metals and metal alloys are very attractive due to the possibility of refinement of the grains to nanometric sizes, which facilitates obtaining high mechanical properties.

Nested order-disorder framework containing a crystalline matrix with self-filled amorphous-like innards

open access: yesNature Communications, 2022
The synthesis and characterization of new crystalline-amorphous hybrid materials is challenging. Here, the authors report the preparation of a nested order-disorder framework by applying high pressure to a nested copper chalcogenide Cu12Sb4S13.

Effect of microstructure refinement of pure copper on improving the performance of electrodes in electro discharge machining (EDM)

open access: yesScientific Reports, 2023
The paper presents an analysis of the impact of plastic deformation using hydrostatic extrusion (HE) on the structural, mechanical and functional properties of pure copper for use as electrodes in the process of electro discharge machining (EDM). As part

Ambient and high-pressure electrical transport and structural investigations of magnetic Weyl semimetal PrAlGe [PDF]

open access: yesarXiv, 2023
We present ambient and high-pressure electrical transport and structural properties of recently discovered magnetic Weyl semimetal PrAlGe. Electrical resistivity at ambient pressure shows an anomaly at $T_C$ = 15.1 K related to the ferromagnetic transition. Anomalous Hall effect (AHE) is observed below $T_C$.

New high-pressure phase and equation of state of Ce2Zr2O8 [PDF]

open access: yesJOURNAL OF APPLIED PHYSICS 111, 053519 (2012), 2012
In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase of Ce2Zr2O8 transforms to a rhombohedral structure beyond 5 GPa with a feeble distortion in the lattice. Pressure evolution of unit-
