Peak-effect and surface crystal-glass transition for surface-pinned vortex array
The peak effect has been investigated in clean Nb crystals with artificially corrugated surfaces by measuring the linear surface impedance in the 1kHz1MHz frequency range. From a two-mode analysis of the complex spectra, we establish that vortex dynamics is governed by surface pinning and deduce the associated vortex slippage length. We demonstrate experimentally and theoretically that the peak...

Effect of Surface Roughness on Vortex Length and Efficiency of Gas-oil Cyclones through CFD Modelling
Separation of suspended droplets in a fluid flow has been a great concern for scientists and technologists. In the current study, the effect of the surface roughness on flow field and the performance of a gas-oil cyclone is studied numerically. The droplets and the turbulent airflow inside the cyclone are considered to be the discrete and continuous phases respectively. The Reynolds stress mode...
متن کاملCrystal Nucleation Using Surface-Energy-Modified Glass Substrates
Systematic surface energy modifications to glass substrates can induce nucleation and improve crystallization outcomes for small molecule active pharmaceutical ingredients (APIs) and proteins. A comparatively broad probe for function is presented in which various APIs, proteins, organic solvents, aqueous media, surface energy motifs, crystallization methods, form factors, and flat and convex su...
متن کاملVortex Glass Transition in High Tc Superconductor
Zhenhua Ning Department of Physics, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA (Dated: December 13, 2006) Abstract This paper tries to give a clear description of the motion of vortex and the vortex glass transitions in high Tc superconductors from both theoretical analysis and experimental observation. Then a controversy of the location of the vortex glass transition in ...
