Study of Polyethylene Crystallization
Dans l'industrie, les produits finis en plastique sont fabriqués par diverses techniques de traitement telles que le moulage par compression, le moulage par injection, le moulage par soufflage, l'extrusion, etc. Ces opérations impliquent l'exposition de résines polymères à de nombreux conditions …

Online polymer crystallization experiment
… for online remote operation of a polymer crystallization experiment was refined, beta tested in actual use conditions, and extended based on feedback from those tests. In addition, an application for graphically simulating macroscopic crystal spherulite growth was developed for use as an …

Crystallization Behavior of Bisphenol-A Polycarbonate: Effects of Crystallization Time, Temperature, and Molar Mass
Crystallization and multiple melting behavior of bisphenol-A polycarbonate (PC) was investigated using differential scanning calorimetry (DSC) for the monitoring of thermal behavior and atomic force microscopy (AFM) for the morphology study. The exceedingly slow crystallization kinetics of PC and …

Order phenomena in polymer crystallization
… influence of order phenomena in polymer melts on crystallization kinetics has been investigated by means of nuclear magnetic resonance (NMR) spectroscopy. In particular the so-called memory effect in syndiotactic polypropylene (s-PP) and the influence of entangled polymer chains (entanglements) on …

Heterogeneous nucleation in polymer crystallization
… between the nuclei, with no changes in the crystallization kinetics. The extent of the shift in the crystallisation temperature of a heterogeneously nucleated polymer has been found to be related to the initial number of spherulites present in the un-nucleated polymer. The highest shift in …

Crystallization and dissolution of electrolyte salts
Η κρυστάλλωση και η διάλυση αλάτων αποτελούν σημαντικές διεργασίες οι οποίες συνεισφέρουν στην φθορά των μνημείων της πολιτιστικής μας κληρονομιάς, τα οποία έχουν κατά κύριο λόγο κατασκευασθεί από δομικά υλικά όπως ο ασβεστόλιθoς και το μάρμαρο. Η κρυστάλλωση ευδιάλυτων αλάτων (π.χ. θειϊκό νάτριο, …

Precursor phases in non-classical crystallization
… of this thesis is to understand molecular crystallization as a multistep process with or without polymeric additives, including transient liquid-liquid phase separation, nanocrystal nucleation within the dense phase, and subsequent nanocrystal self-assembly or self-organization in sequence. …

Cooling and crystallization of komatiite flows.
… in the upper layers of flows grew by constrained crystallization arising from strong thermal pradients and the high lattice thermal conductivity and near-infrared transparency of olivine (3-5 times greater than that of the surrounding melt). Such crystals exhibit a very strong preferred …

Purification and crystallization of spliceosomal snRNPs
In Eukaryoten werden die nicht-kodierenden Sequenzen des prä-mRNA-Transkripts durch einen Ribonukleoproteinkomplex, das Spleißosom, entfernt. Die Hauptkomponenten des Spleißosoms sind die Ribonukleoproteinpartikel (snRNPs) U1, U2, U4, U5 und U6. Neben der U1 small nuclear RNA (snRNA) enthält das U1 …
