Wavenumber distribution in Hopf-wave instability: The reversible selkov model of glycolytic oscillation

Article Abstract:

The short-wave instability due to Horpf bifurcation in a reaction-diffusion model of glycolytic oscillations is investigated. Very low values of the ration d of the diffusion coefficient of the inhibitor and that of the activator (ADP) do help to create short waves, whereas high values of the ratio d and the complexing reaction of the activator ADP reduces drastically the wave-instability domain, generating much longer wavelengths.

Hydroxy double salt anion exchange kinetics: Effects of precursor structure and anion size

Article Abstract:

The details of anion exchange reactions of two layered hydroxy double salts, zinc copper hydroxy acetate (ZCA), nickel zinc hydroxy acetate, and a related layered material, zinc hydroxy acetate, was described at room temperature using (super 1)H NMR and powder X-ray diffraction. The reaction of ZCA with formate anions exhibited a unique zeroth-order kinetics release of acetate.

Global optimization of H-passivated Si clusters at the ab initio level via the GAM1 semiempirical method

Article Abstract:

A genetic algorithm (GA)-based procedure for finding the global minimum of medium-sized Si(sub x)H(sub y) clusters at the ab initio level is presented. Semiempirical calculations are used to prescreen the relative energies of the many locally optimized Si(sub x)H(sub y) structures generated by the GA.
