Dynamics of n-alkanes: Comparison to Rouse Model
The crossover to Rouse-like behavior for the self-diffusion constant D, the viscosity η, and the equilibrium structural statistics of n-alkanes (6 ≤ n ≤ 66) is studied numerically. For small n the chains are non-Gaussian and the mean squared end-to-end distance 〈R2〉 is greater than 6〈R2 G〉, where 〈R2 G〉 is the mean squared radius of gyration. As n increases, 〈R2〉/〈R2 G〉 → 6(1 + a/n), where a de...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولDynamics of Rouse polymers in Maxwell fluids
A generalization of the Rouse model of the dynamics of polymers in solution is proposed. The motion of long polymer chains is considered to be due to exponentially correlated random forces driving the polymer segments, which is a more realistic model than the approximation of white thermal noise in the standard theory. Due to the fluctuationdissipation theorem such a model is consistent with th...
متن کاملCatalytic dehydroisomerization of n-alkanes to isoalkenes
An equilibrated mixture of pentene isomers was produced by dehydroisomerization of n-pentane on catalysts consisting of Pt clusters within [Fe]ZSM-5 channels. These catalysts showed high isomerization rates, excellent stability even without added H2, and isopentene selectivities above 60%. Metal sites on Pt clusters dehydrogenate n-alkanes and n-alkenes formed undergo skeletal rearrangements wi...
متن کاملRouse dynamics of colloids bound to polymer networks.
We present experimental evidence of a transition in the short-time Brownian motion of colloids from diffusive to subdiffusive, Rouse-like. This transition is seen for particles that are bound, through physical adsorption, to transient polymer networks. The characteristic Rouse scaling of the mean square particle displacement with radical t, found in the experiments, is rationalized using an ana...
