Molecular basis of the shish-kebab morphology in polymer crystallization.
In the rich and long-standing literature on the flow-induced formation of oriented precursors to polymer crystallization, it is often asserted that the longest, most extended chains are the dominant molecular species in the "shish" of the "shish-kebab" formation. We performed a critical examination of this widely held view, using deuterium labeling to distinguish different chain lengths within ...
متن کاملInterfacial load transfer in polymer/carbon nanotube nanocomposites with a nanohybrid shish kebab modification.
Interfacial properties are known to have a critical effect on the mechanical properties of a nanocomposite material system. Here, the interfacial load transfer in a carbon nanotube (CNT)/nylon-11 composite was studied with a CNT/nylon-11 nanohybrid shish kebab (NHSK) structure modification using Raman spectroscopy. Characterization of the polymer crystal in the NHSK using differential scanning ...
متن کاملRuthenium and Osmium as Hydrogenation Catalysts
Little attention has been given to the use of ruthenium and osmium as catalysts for vapour-phase reactions. This paper shows that both these metals when supported on alumina possess signijcant activity for the hydrogenation of unsaturated hydrocarbons. In the hydrogenation of butene, butadiene and acetylene their activity is comparable with that shown by the other platinum group metals, althoug...
متن کاملnitrido complexes of ruthenium and osmium
Ru=O complexes have been demonstrated to be competent oxidants for oxidation of saturated hydrocarbons and epoxidat ion of alkenes . Photoexcitation of transdioxoosmium(V1) gives rise to super-oxidizing complexes having EO >2.2 V vs. n.h.e.. Some cationic RuZN and OsZN complexes are good model system for study of the mechanism of metalcatalysed oxidation of ammonia to nitrite and activation of ...
