Role of a Pb2+ stabilizer in the electroless nickel plating system: a theoretical exploration

Article Abstract:

The electroless nickel (EN) plating mechanism is explained, by applying the structure of the Stern-Grahame electrical double layer (EDL) and the electronic tunneling theory of the quantum mechanics. Two mathematical models are developed to explain the dependence of Ni plating rate and phosphorus content of a Ni-P deposit layer on the Pb2+ concentration, which indicate that lead atoms embedded in the Ni-P lattice can reduce work function of the plating frontier.

Influence of frequency shifts on electron transfer processes

Article Abstract:

The quantum theory of electron transfer processes is extended to treat frequency changes between initial and final electronic states. The results emerge in a compact, physically transparent Marcus type form and also exhibit an interesting situation where frequency changes can balance against traditional reorganization energy.

Quantum mechanical/molecular mechanical molecular dynamics simulations of cytidine deaminase: from stabilization of transition state analogues to catalytic mechanisms.

Article Abstract:

The action-site interactions in stabilizing zebu larine 3,4, hydrate and transition state is described. The stability and integrity of TSA's in the active sites can provide more information with regard to the origin of transition state stabilization.
