When heated by an electronic cigarette, propylene glycol and glycerol produce a nicotine-carrying-aerosol. This hygroscopic/hyperosmolar aerosol can deposit deep within the lung. Whether these deposits trigger local inflammation and disturb pulmonary gas exchanges is not known. The aim of this

(R)-2-Hydroxybutyric acid ((R)-2-HBA) is an important building block for azinothricin family of antitumour antibiotics and biodegradable poly(2-hydroxybutyric acid). However, optically active (R)-2-HBA could not be produced through microbial fermentation or chemical synthesis. Several biocatalytic methods have been reported for the

Three flavones (quercetin, myricetin and amentoflavone) were extracted from Chamaecyparis obtusa leaves using deep eutectic solvents (DESs) as additives to conventional extractions solvents. Sixteen DESs were synthesized from different salts and hydrogen bond donors. In addition, C. obtusa was extracted
