The level of chlorideions (Cl⁻) in sweat is a recognized biomarker for the genetic disorder cystic fibrosis (CF). The accurate quantitation of chlorideions in sweat is therefore a vital diagnostic tool for this life-threatening disease. In this work, a fluorescent, chlorideion chemosensor was developed by exploiting the strong interaction between silver (Ag+) and chlorideions. Using the concept

Efficient and general methods for the synthesis of amines remain in high demand in the chemical industry. Among the many known processes, catalytic hydrogenation is a cost-effective and industrially proven reaction and currently used to produce a wide array of such compounds. We report a homogeneous nickel catalyst for hydrogenative cross coupling of a range of aromatic, heteroaromatic, and aliphatic
