Quantum dots (QDs) were immobilized on an ultra-flat Au surface by using amide binding between the carboxyl groups on the QDs and the amino groups of the self-assembled monolayer on the surface. The number density of the QDs estimated by atomic force microscopy (AFM) agreed with the quantity of QDs estimated by X-ray photoelectron spectroscopy and fluorescence microscopy. QDs were also immobilized...
The relationship between the surface structures of skin layers of crosslinked aromatic polyamide composite reverse osmosis (RO) membranes and their RO performances have been studied using two surface analytical techniques: SEM and AFM. As a result, it was found that RO membranes whose skin layer surface structures were rough produced high fluxes, and an approximately linear relationship existed between...
