Selective desolvation in two-step nucleation mechanism steers crystal structure formation

Illustrated is a two-step nucleation process, where solute molecules in the solution are first partially desolvated to form locally dense liquid clusters followed by selective desolvation to yield crystalline solids.

Competing repair strategies for word-final obstruent-liquid clusters in northern metropolitan French

ABSTRACT French licenses word-final obstruent-liquid clusters (table /tabl/; souffre /sufʁ/). These clusters may be realised faithfully resulting in an apparent violation of the sonority sequencing principle (Clements, 1990). Yet, the clusters can also be repaired in one of two ways: (1) through the reduction of the cluster (i.e. [tab]) or (2) through the epenthesis of a schwa vowel, resyllabifying the cluster into the onset position (i.e. [ta.blə].) In this article, I investigate which factors condition the realisation of word-final obstruent-liquid clusters. The results are formalised in Maximum Entropy Grammar (Goldwater and Johnson, 2003), but evidence for effects of style and speaker age require the scaling of several constraints (Coetzee and Kawahara, 2013). This study sheds light on these curious clusters, while raising new questions about the interaction of grammatical and non-grammatical factors.

1-Alkyl-3-Methylimidazolium Cation Binding Preferences in Hexafluorophosphate Ionic Liquid Clusters Determined Using Competitive TCID Measurements and Theoretical Calculations

Ionic liquids (ILs) exhibit unique properties that have led to their development and widespread use for a variety of applications. Development efforts have generally focused on achieving desired macroscopic properties...

Positional factors in syllabification

From the perspective of standard generative phonological theory, syllable structure is not recorded in the lexicon but it is obtained by means of a syllabification algorithm based on a series of principles. In a given language, the algorithm should parse obstruent+liquid clusters as tautosyllabic both in word-initial and word-internal positions. The tautosyllabic parse as a branching onset complies with all principles on which the syllable-building algorithm is based. In standard theory, if branching onsets of obstruent+liquid are allowed in a language and documented in word-initial position, tautosyllabic parse is predicted to hold also word-internally. Likewise, Kaye’s (1992) Uniformity Principle makes the same prediction, since it states that sequences of contiguous positions that are in a governing relation and contain the same phonological material have the same constituent structure. The present paper draws attention to empirical data showing obstruent+liquid clusters being parsed tautosyllabically in word-initial position and heterosyllabically in word-internal position in the same language. An account is proposed to explain the data discussed, claiming that positional factors may also be relevant in determining syllabification.
