摘要:Abstract(#br)In this paper, we present a novel physics based analytic model for C – V characteristics of planar Schottky diodes made by a GaAs MESFET process and used in GaAs MMIC. The model focuses on small dimensions, planar technology and ion implantation technology, and ...

摘要:Abstract(#br)The molecular imprinting technique was applied for the preparation of a polymer selective for an acidic drug, 5,5-diphenylhydantoin in a polar solvent using acrylamide as the hydrogen-bonding functional monomer. The binding characteristics of the imprinted polym...

摘要:Abstract(#br)In this paper, the cone theory and monotone iterative technique are used to investigate the minimal nonnegative solutions of initial value problems (IVPs) for n th order nonlinear integro-differential equations of mixed type on an infinite interval in a Banach space.
