High-resolution thermal expansion measurements under helium-gas pressure
(2012-08-01)
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4K ≤ T ≤ 300K and hydrostatic pressure P ≤ 250MPa. Helium ( 4He) is ...

Effect of pressure-assisted thermal annealing on the optical properties of ZnO thin films
(2012-12-21)
ZnO thin films were prepared by the polymeric precursor method. The films were deposited on silicon substrates using the spin-coating technique, and were annealed at 330°C for 32h under pressure-assisted thermal annealing ...

Pressure-induced phase transitions in Zr-rich PbZr1-xTixO3 ceramics
(2001-08-20)
A Raman study of structural changes in the Zr-rich PbZr1-x TixO3 (PZT) system under hydrostatic pressures up to 5.0 GPa is presented. We observe that externally applied pressure induces several phase transitions in PZT ...

Characterization of V-doped SnO 2 nanoparticles at ambient and high pressures
(IOP Publishing, 2018-12)
Nanoparticles of V-doped SnO2 with stoichiometry Sn1-xO2Vx (x = 0.05, 0.075, 0.125) have been synthesized by a co-precipitation method. Their structural, vibrational, and nuclear properties have been characterized by x-ray ...
