Micellar-enhanced ultrafiltration has been carried out to investigate the separation of phenol from an aqueous stream via hollow fiber membranes. First, phenol is solubilized into the micelles of cationic surfactant such as hexadecyltrimethylammonium chloride (CTAC) and hexadecylpyridinium chloride (CPC), and then the micellar solution is treated continuously through an ultrafiltration membrane module. In the present study we examine the effects of retentate concentration, molecular weight cut-o

Stable dispersion of colloidal indium tin oxide nanoparticles was prepared by using indium tin oxide nanopowder, organic solvent, and suitable dispersants through attrition process. Various comminution parameters during the attrition step were studied to optimize the process for the stable dispersion of indium tin oxide sol. The transparent and conductive films were fabricated on glass substrate using the indium tin oxide sol by spin coating process. To obtain antireflective function, partially

Abstract The growing demand for energy storage systems and electric vehicles has intensified research on Li-ion batteries, in which the cathode significantly influences both cost and performance. This review focuses on recent advances in atomic layer deposition (ALD) as a strategy to enhance cathode materials through surface modification and doping. Originally developed for the semiconductor industry, ALD enables conformal and precisely controlled coating on substrates with high-aspect-ratio str
