New polymers synthesis by organocatalyzed step-growth polymerization of aldehydic monomers : polyaldols, linear polybenzoin and hyperbranched polyacetals

The higher vertical growth rate of the spiral mounds on Pt(111) reflects the different incorporation mechanisms for atoms in the top region and can be formally represented by

First, we assume thon the diffusion length tD (defined from the correlation function (2.4) in the asymptotic Poisson regime) is independent of the surface inclination m, and of

Concerning the synthesis models, it would be interesting to make further signal analyses on recorded sounds in order to define specific amplitude and frequency modulation laws for

Two articles on global ethics debate its place in the dis- cipline of applied ethics; the conclusion is that global ethics involves a theoretical reworking of key ethical needs
