Thermal-stimulated pressure and current studies of bound water in lysozyme
Biophysical Journal, 1977 The state of bound water in crystalized lysozyme was studied by four techniques: electret thermal depolarization currents, thermal-stimulated pressure, isothermal polization decay, and thermogravimetry. Hydration levels ranged from 0 to 40 mg water/g protein.

Correlation between the electric and acoustic signals emitted during compression of brittle materials [PDF]
Fracture and Structural Integrity, 2017 An experimental protocol is described including a series of uni¬axial compression tests of three brittle materials (marble, mortar and glass). The Acoustic Emission (AE) technique and the Pressure Stimulated Currents (PSC) one are used since the ...

Piezo stimulated currents in marble samples: precursory and concurrent-with-failure signals [PDF]
Natural Hazards and Earth System Sciences, 2003 The Earth’s electric field transient variations are promising candidates of earthquake precursors. In order to study the physical mechanisms of such precursory signals, laboratory experiments of uniaxial compression were carried out.

Procedia Structural Integrity, 2017 Abstract: An experimental protocol was implemented to investigate possible correlations between the data provided by the Acoustic Emissions and the Pressure Stimulated Currents techniques and the role of the loading rate induced. Prismatic cement-mortar specimens were subjected to three-point bending (3PB) under various loading rates.
