Pressure-Induced Polymerization: Addition and Condensation Reactions
Molecules, 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]
Bulletin 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.

Nanocrystalline iron at high pressure [PDF]
, 2001 X-ray diffraction measurements were performed on nanocrystalline iron up to 46 GPa. For nanocrystalline epsilon-Fe, analysis of lattice parameter data provides a bulk modulus, K, of 179±8 GPa and a pressure derivative of the bulk modulus, K[prime], of 3 ...

Time-dependent exchange creates the time-frustrated state of matter
Scientific Reports, 2022 Magnetic systems governed by exchange interactions between magnetic moments harbor frustration that leads to ground state degeneracy and results in the new topological state often referred to as a frustrated state of matter (FSM).
