Dilution wave and negative-order crystallization kinetics of chain molecules. Physical Review Letters 85, 4397-4400.http://focus.aps.org/story/v6/st21http://repository.kln.ac.lk/handle/123456789/10085We show that the crystal growth rate of a very long-chain n-alkane C198H398 from solution can decrease with increasing supersaturation and follow strongly negative order kinetics. The experimental behavior can be well represented by a theoretical model which allows the molecule to attach and detach as either extended or folded in two. The obstruction of extended-chain growth by unstable folded depositions increases disproportionately with increasing concentration. As a consequence of this abnormal kinetics, a “dilution wave” can propagate and trigger a folded-to-extended-chain transformation on its way.enArticle
