Asymptotic Conformal Invariance of SU(2) and Standard Models in Curved Space-time
The asymptotic conformal invariance of some SU(2) model and Standard Model in
curved space-time are investigated. We have examined the conditions for
asymptotic conformal invariance for these models numerically.Comment: 13 pages, Revtex3.
Conformally Coupled Induced Gravity with Gradient Torsion
It is found that conformally coupled induced gravity with gradient torsion
gives a dilaton gravity in Riemann geometry. In the Einstein frame of the
dilaton gravity the conformal symmetry is hidden and a non-vanishing
cosmological constant is not plausible due to the constraint of the conformal
coupling.Comment: 8pages, LaTeX, no figure, to be appeared in PR

Photoelectrochemical ion concentration polarization : a microfluidic ion filtration system using light-driven electrochemical reactions
We report an ion separation or filtration method used in microchannel called photoelectrochemical ion concentration polarization (pICP). As a variant of faradaic ion concentration polarization (fICP), pICP utilizes TiOâ‚‚ photoelectrochemistry to form an ion depletion zone (IDZ) with light. A microfluidic device with TiOâ‚‚ photoanode and Pt cathode generated IDZ near the cathode by generating a corresponding electrochemical reaction. Local electric field near the cathode was amplified with TiOâ‚‚ irradiation. Furthermore, on-chip solution conductivity measurement confirmed decrease in ion concentration as a consequence of pICP ion filtration.Chemistr
