Web5 dec. 2024 · We report a one-step strategy to synthesize, in situ, highly water-dispersible NaYF 4 : Yb/Er upconversion nanoparticles (UCNPs) by employing dicarboxylic acids. The dicarboxylic acids serve as a type of dual-purpose surface ligand for both controlling the growth and enabling the water dispersibility of the NaYF 4 : Yb/Er UCNPs. It is found that … Web2 dagen geleden · Despite recent advancements in the development of catalytic asymmetric electrophile induced lactonization reactions of olefinic carboxylic acids, the archetypical hydrolactonization has long remained an unsolved and well-recognized challenge. Here, we report the realization of a catalytic asymmetric hydrolactonization using a confined … WebPM10 samples were collected from Huangshi (HS) city, Central China during April 2012 to March 2013, and were analyzed for short-chain saturated dicarboxylic acids (diacids) using a capillary gas chromatograph (GC). We found that oxalic acid (C2, 318 ± 104 ng·m−3) was the most abundant diacid species, followed by malonic acid (C3, 25.4 ± … how do i get amazon prime on my tv with roku
