Unexpected effects of catalytic amounts of additives on crystallization from the gas phase: Depression of the sublimation temperature and polymorph control
(American Chemical Society, 2016-04-11)
Sublimation of carbamazepine, piracetam, diflunisal, and p-minobenzoic acid is enhanced by the presence of additives. Temperature reductions and polymorph control have been observed. Sublimation of carbamazepine containing ...
The natural bile acid surfactant sodium taurocholate (NaTC) as a coformer in coamorphous systems: Enhanced physical stability and dissolution behavior of coamorphous drug-NaTc systems
(Elsevier, 2018-10-28)
The amorphization of 18 different drugs on milling with one mole equivalent sodium taurocholate (NaTC) was investigated. In all cases the X-ray powder pattern showed an amorphous halo after milling at room temperature or ...
Planar [Ni-7] discs as double-bowl, pseudo metallacalix[6]arene host cavities
(RSC, 2010-09-19)
We report three heptanuclear[Ni-7] complexes with planar disc-like cores, akin to double-bowl metallocalix[6]arenes, which form molecular H-bonded host cavities.
