Potato tuber permittivity during deformation in compression [PDF]
Research in Agricultural Engineering, 2007 Potato tuber specimens of two varieties (Nicola and Saturna) were deformed in a compression loading/unloading test. The tuber complex permittivity spectrum at frequencies 0.1-500 kHz was measured repeatedly during the deformation.

Chiral multi-curved shell metamaterials integrating compression-torsion and buckling mechanisms for ideal energy absorption [PDF]
Nature CommunicationsMetamaterials with compression-torsion or buckling mechanism have demonstrated significant potential for energy absorption. However, compression-torsion metamaterials easily trigger deformation, resulting in low load-bearing capacity, and buckling ones ...

Effects of Pre-Strain on the Evolution of Microstructure and Strain Hardening of Extruded Az31 Magnesium Alloy [PDF]
Materials Research, 2017 Pre-compression 3% and pre-stretch 3% subsequent annealing at 200ºC for 2h are conducted on AZ31 magnesium alloys, then inverse tensile and compressive deformation are carried out at room temperature, respectively.

Superconductivity in Compression-Shear Deformed Diamond
Physical Review Letters, 2020 Diamond is a prototypical ultrawide band gap semiconductor, but turns into a superconductor with a critical temperature T_{c}≈4 K near 3% boron doping [E. A. Ekimov et al., Nature (London) 428, 542 (2004)NATUAS0028-083610.1038/nature02449]. Here we unveil a surprising new route to superconductivity in undoped diamond by compression-shear deformation ...
