Recent developments in sonochemical polymerisation.
High intensity ultrasound has been applied to two classes of step-growth polymerisation. The ring-opening polymerisation of cyclic lactones to polyesters was accelerated under 20 kHz ultrasound but, in the case of delta-valerolactone, sonication also promoted a depolymerisation reaction so that the molecular weight fell during later stages of the reaction. Sonication was also applied to the pre...
متن کاملdas g?ttliche aus der sicht rumis und der romantiker
die kultur eines jeden landes kann als ein nicht in sich abgeschlossenes system angesehen werden, das durch das handeln der menschen, durch anpassung, ubernahme, bereicherung etc. mit unterschiedlichem grad der dynamik, st?ndig im wandel ist. als eine ihrer auspr?gungen, werden in der literatur verschiedener kulturkreise die interkulturellen gemeinsamkeiten deutlich sichtbar. der ursprung vorha...
متن کاملThe prion paradox: infection or polymerisation?
A weak but significant similarity was found between the prion protein (PrP) and some transcription factors and zinc-finger proteins. A possible interpretation of this similarity is that the PrP is a metal- (copper-) binding transcription factor and might behave like a Zn-finger protein, with the Cu2+ binding to its histidine and serine residues. Copper-binding could create intramolecular bridge...
متن کاملReconstitution of three-phase microtubule polymerisation dynamics
Cytoplasmic microtubules (MTs) undergo growth, shrinkage, and pausing. However, how MT polymerisation cycles are produced and spatiotemporally regulated at a molecular level is unclear, as the entire cycle has not been recapitulated in vitro with defined components. In this study, we reconstituted dynamic MT plus end behaviour involving all three phases, by mixing tubulin with five Drosophila p...
متن کاملLaser Nephelometry Measurement of Fibrin Polymerisation
Ever since the description by Green' of a modification of the colorimetric method reported by Soria2 to determine the kinetics of fibrin polymerisation induced by reptilase was published, no attempts have been made to improve the sensitivity of the method. The controversial association of the abnormalities of fibrin polymerisation detected by traditional methods with the presence and severity o...
