Studies on preparation of weak acid-strong base type charge-mosaic membrane. II Preparation of weak acid-strong base type charge-mosaic membrane in thiol-quarternary amine groups.

Photoinduced strong acid-weak base reactions in a polar aprotic solvent.

The excited-state proton transfer (ESPT) of the strong photoacid, N-methyl-7-hydroxyquinolinium, was studied in the presence of different weak bases such as methanol, ethanol, and dimethyl sulfoxide in an aprotic solvent of acetonitrile. Here, we present chemical kinetics analysis of the ESPT mechanism to explain biphasic fluorescence decay of the parent photoacid and the sign reversal of the r...

Acid precipitation: strong and weak acids.

The Charge Ordered State from Weak to Strong Coupling

We apply the Dynamical Mean Field Theory to the problem of charge ordering. In the normal state as well as in the Charge Ordered (CO) state the existence of polarons, i.e. electrons strongly coupled to local lattice deformation, is associated to the qualitative properties of the Lattice Polarization Distribution Function (LPDF). At intermediate and strong coupling a CO state characterized by a ...

Strong ions, weak acids and base excess: a simplified Fencl-Stewart approach to clinical acid-base disorders.

BACKGROUND The Fencl-Stewart approach to acid-base disorders uses five equations of varying complexity to estimate the base excess effects of the important components: the strong ion difference (sodium and chloride), the total weak acid concentration (albumin) and unmeasured ions. Although this approach is straightforward, most people would need a calculator to use the equations. We proposed fo...

Ion transport through diffusion layer controlled by charge mosaic membrane

The kinetic transport behaviors in near interface of the membranes were studied using commercial anion and cation exchange membrane and charge mosaic membrane. From chronopotentiometry above the limiting current density, the transition time was estimated. The thickness of boundary layer was derived with conjunction with the conventional limiting current density and the transition time from stea...
