Cerium(III) nitrate hexahydrate efficiently catalyzes the three-component Biginelli reaction under solvent-free conditions of an aldehyde, a beta-keto ester or beta-diketone and urea or thiourea to afford the corresponding 3,4-dihydropyrimidin-2(1H)-ones or -thiones in excellent yields.
In this paper, an electrokinetic flow of a water electrolyte in a nano-channel will be studied. This study will be with existence of the Electric Double Layer (EDL) and fully analytical. Governing equation for the EDL is Poisson-Boltzmann. In addition, Navier-Stokes equations for electrolyte flow, Species and mass conservation equations are in use. Induced… (More)
