In recent years many efforts have been devoted to the screening and the study of new solid-
state forms of old active pharmaceutical ingredients (APIs) with salification or co …

The field of isotope effects has expanded exponentially in the last decade, and researchers
are finding isotopes increasingly useful in their studies. Bringing literature on the subject up …

The hydrogen bond interaction of pyridine with the silanol groups of the inner surfaces of
MCM-41 and SBA-15 ordered mesoporous silica has been studied by a combination of solid …

The Lewis acidity of isolated framework metal sites in Beta zeolites was characterized with
15N isotopically labeled pyridine adsorption coupled with magic-angle spinning nuclear …

Hydrogen bonding in ionic liquids based on the 1-(2′-hydroxylethyl)-3-methylimidazolium
cation ([C2OHmim]+) and various anions ([A]−) of differing H-bond acceptor strength, viz …

A cancer candidate, compound 1, is a weak base with two heterocyclic basic nitrogens and
five hydrogen-bonding functional groups, and is sparingly soluble in water rendering it …

Cocrystals and amorphous solid dispersions have generated interest in the pharmaceutical
industry as an alternative to more established solid delivery forms. The identification of …

Heterogeneous Brønsted acid catalysts are tremendously important in industry, particularly
in catalytic cracking processes. Here we show that these Brønsted acid sites can be directly …

Hydrogen bond geometries and 1 H NMR chemical shifts of OHO hydrogen‐bonded
systems have been analyzed using an improved valence bond order model. This model …

The low-temperature 1H, 19F, and 15N NMR spectra of mixtures of collidine-15N (2, 4, 6-
trimethylpyridine-15N, Col) with HF have been measured using CDF3/CDF2Cl as a solvent …
