Pressure techniques are experimental methods that apply controlled hydrostatic or uniaxial pressure to a sample to modify and probe its structural, electronic, magnetic, or thermodynamic properties. Implemented using devices such as diamond anvil cells, piston-cylinder cells, or multi-anvil presses, these techniques can generate pressures from fractions of a gigapascal to several hundred gigapascals. They are commonly coupled with in situ probes (e.g., X-ray diffraction, Raman/IR spectroscopy, electrical transport, or neutron scattering) to study phase transitions, equation-of-state behavior, bonding changes, and reaction pathways under extreme conditions relevant to condensed matter physics, materials science, and geoscience.
Scientists at Lawrence Livermore National Laboratory (LLNL) have reported advancements in understanding plasma pressure profiles within flow-stabilized Z-pinch fusion, a candidate for achieving net gain fusion energy in a ...
