Abstract Two new Schiff base derivatives N,N‐dimethyl‐4‐((2‐(phenylthio) phenyl)imino)propenyl)aniline ( CSP ) and 2‐(4‐(dimethylamino)phenyl) allylidene) amino)benzenethiol CSH were synthesized. Sensing mechanism of the sensors was investigated using UV‐Vis spectroscopy in presence various metal ions. The sensor shows high sensitivity selectivity to Cu 2+ over a wide range other ions acetonitrile (ACN)/water (H 2 O) (v/v : 1). can detect by color change from yellow pink. complex...
More frequent and/or longer hemodialysis (HD) has been associated with improvements in numerous clinical outcomes patients on dialysis. Home HD (HHD), which allows more dialysis lower cost and flexibility treatment planning, is not widely used worldwide. Although, retrospective studies have indicated better survival HHD, this issue remains controversial. In multicenter study, we compared thrice-weekly extended HHD in-center conventional (ICHD) a large patient population long-term...
Schiff bases of 2‐(phenylthio)aniline, (C 6 H 5 )SC 4 NCR (R = ( o ‐CH 3 )(C ), ‐OCH ) or ‐CF )), and their palladium complexes (PdLCl 2 were synthesized.

The optically pure binaphthyl-based phosphoramidite ligands and their perfluorinated analogs have been first used for the preparation of chiral palladium nanoparticles (PdNPs). These PdNPs extensively characterized by X-ray diffraction, photoelectron spectroscopy, transmission electron microscopy, 31P NMR, thermogravimetric analysis techniques. circular dichroism(CD) exhibited negative cotton effects. Perfluorinated provided smaller (2.32-3.45 nm) well-defined nanoparticles, in comparison...
