An augmented volume‐based model of the glass transition temperature of 209 molecular liquids

Ulrich P. Preiss, Muhammad I. Saleh

Journal of Pharmaceutical Sciences > 102 > 6 > 1970 - 1980

It is well known that the amorphous state can greatly enhance the bioavailability of drugs. However, comparatively few compounds form either liquids at room temperature or glasses above it. We present qualitative insights as to why some molecules would form glasses instead of crystals and a fast, straightforward, physically well founded, and nonproprietary method to calculate the expected glass transition...

Journal of Organometallic Chemistry > 2008 > 693 > 15 > 2561-2571

The selectivity factor in the separation of lanthanide could be associated with the coordination behaviour. Thus, we observed the study in the solid phase to understand the coordination pattern of Ln(III) with the 18-crown-6 (18C6) ligand. Good selectivity of the rigid 18C6 ligand toward Ln(III) depends on gradually smaller their ionic radii of Ln(III) in the complexes formation in the presence of...
