The generalized Laplace equation of capillarity I. Thermodynamic and hydrostatic considerations of the fundamental equation for interfaces
Boruvka and Neumann\\'s (BN) generalized theory satisfies all the requirements of thermodynamics and mathematics.
Further, to test the BN theory, a hydrostatic treatment of a two phase capillary system is presented. This non-thermodynamic approach...
The generalized Laplace equation of capillarity II. Hydrostatic and thermodynamic derivations of the Laplace equation for high curvatures
Two derivations are given of the generalized Laplace equation of capillarity, which assume constant surface tensions and constant curvature potentials over the surface for highly curved interfaces a priori: one based on hydrostatics and the other...
Hydrostatic pressure induced transformation from δT_c to δl pinning in MgB2
The impact of hydrostatic pressure up to 1.2 GPa on the critical current density (Jc) and the nature of the pinning mechanism in MgB2 have been investigated within the framework of the collective theory. We found that the hydrostatic pressure can...
Giant enhancement in critical current density, up to a hundredfold, in superconducting NaFe0.97Co0.03As single crystals under hydrostatic pressure
progress. Jc at high temperatures in high fields still needs to be further improved, however, in order to meet the requirements of practical applications. Here, we demonstrate a simple approach to achieve this. Hydrostatic pressure can significantly enhance...
Hydrostatic pressure: A very effective approach to significantly enhance critical current density in granular iron pnictide superconductors
current density in the Fe-based superconductors. Here, we propose to use hydrostatic pressure to significantly enhance flux pinning and Tc in polycrystalline pnictide bulks. We have chosen Sr4V2O6Fe2As2 polycrystalline samples as a case study. We...
