The isomorphisms and the center of weak quantum algebras $\omega sl_q(2) $

Abstract

The aim of this paper is to describe the centre as well as the structure of $ \omega sl_{q}(2) $ by applying the deformation of Harish-Chandra homomorphism.

Reversible Pattern Formation through Photolysis

“…The zeta potential of the surface over which the pattern was occurring is clearly significant. For example, a parylene, poly(chloro- p -xylylene), coated silicon dioxide surface (zeta potential ∼ −1 mV) exhibited enhanced patterning (see video IV in the Supporting Information) where particles moved at ∼18 μm/s as compared to 0.6 μm/s for the silver on uncoated silicon dioxide (zeta potential ∼ −70 mV) for particles of identical zeta potential. , Upon substituting ξ obtained from eq 6 into eq 4, we can solve for the theoretical velocity of the particle where velocity is both a function of the zeta potential of the particle (electrophoretic component) and the pressure gradient created by the chemical reaction (chemiphoretic component). Despite the approximations discussed above, our predicted velocities (Table ) have the correct direction and are generally within an order of magnitude of our experimental results for a series of negative particles with different zeta potentials and positively charged amidine particles and for two different surfaces (silver/silicon dioxide and silver/parylene).…”
