Welding Molecular Crystals [PDF]

open access: yesJournal of the American Chemical Society, 2015
Both for fundamental and applied sciences, the design of complex molecular systems in the crystalline phase with strict control of order and periodicity at both microscopic and macroscopic levels is of prime importance for development of new solid-state materials and devices.

Plastic/ferroelectric molecular crystals: Ferroelectric performance in bulk polycrystalline forms

open access: yesAPL Materials, 2021
Plastic crystals are a class of compounds composed of small molecules with globular structures. Plastic crystals exhibit various unique features, most of which arise from the rotator motion and orientational disorder of the constituent molecules.

Sonofragmentation of Molecular Crystals [PDF]

open access: yesJournal of the American Chemical Society, 2011
Developing processes for the production of active pharmaceutical ingredients (APIs) with a specific crystal size or polymorph distribution is critical for improved drug delivery by aerosolization, injection or ingestion, for control of bioavailability, and for economy of preparation.

Low-density preference of the ambient and high-pressure polymorphs of dl-menthol

open access: yesIUCrJ, 2023
Lower-density polymorphs of dl-menthol were nucleated and crystallized in their high-pressure stability regions. Up to 0.30 GPa, the triclinic dl-menthol polymorph α, which is stable at atmospheric pressure, is less dense than a new β polymorph, which ...

Unveiling the self-association and desolvation in crystal nucleation

open access: yesIUCrJ, 2021
As the first step in the crystallization process, nucleation has been studied by many researchers. In this work, phenacetin (PHEN) was selected as a model compound to investigate the relationship between the solvent and nucleation kinetics.

Extraordinary anisotropic thermal expansion in photosalient crystals

open access: yesIUCrJ, 2020
Although a plethora of metal complexes have been characterized, those having multifunctional properties are very rare. This article reports three isotypical complexes, namely [Cu(benzoate)L2], where L = 4-styrylpyridine (4spy) (1), 2′-fluoro-4 ...

Acemetacin cocrystal structures by powder X-ray diffraction

open access: yesIUCrJ, 2017
Cocrystals of acemetacin drug (ACM) with nicotinamide (NAM), p-aminobenzoic acid (PABA), valerolactam (VLM) and 2-pyridone (2HP) were prepared by melt crystallization and their X-ray crystal structures determined by high-resolution powder X-ray ...
