A Rapid and Sensitive Method for the Determination of Chitosan Concentration by NMR Relaxometry
ABSTRACT A rapid, reagent‐free method for the quantification of chitosan in aqueous solutions was developed using 1H nuclear magnetic resonance (NMR) relaxometry. Transverse relaxation times (T2) of chitosan solutions (5–1000 mg/L) were measured with a Carr–Purcell–Meiboom–Gill (CPMG) sequence on a benchtop NMR relaxometer.

Platinum group pincer complexes are highly efficient catalysts. Additionally, their high activity enables challenging transformations with low catalyst loading. Herein, we summarize the most relevant advances of catalysis involving platinum group pincer complexes. The use of pincer complexes based on platinum group metals is undoubtedly one of the most

Cholesteric Liquid Crystal Displays as Optical Sensors of Barbiturate Binding
The influence on the optical properties of cholesteric liquid crystal displays (LCDs) was examined for neutral molecule binding by mesogen/receptors in the mesomorphic phase. The motivation was to prepare neutral molecule sensors that use a colour change
