Aqueous emulsion acrylic adhesive was prepared by batch polymerization With 2-ethylhexyl acrylate (2-EHA) and butyl (BA) as soft monomers, methyl methacrylate (MMA) hard monomer, acid (AA), amide (AM) hydroxyethyl (HEA) hydrophilic functional dodecanethiol (NDM) molecular weight regulator, Sodium dodecyl benzene sulfonate (SDBS) octyl phenol polyoxyethylene ether (op-10) mixed emulsifiers, ammo...

A new bio-inspired method was applied in this study to simultaneously improve the monovalent anion selectivity and antifouling properties of anion exchange membranes (AEMs). Three-layer architecture was developed by deposition of polydopamine (PDA) and electro-deposition of N-O-sulfonic acid benzyl chitosan (NSBC). The innermost and outermost layers were PDA with different deposition time. The ...

Understanding adhesion of micro-particles particularly microcapsules containing a functional active on fabric surface is crucial to effective delivery of the active to the latter. Fabric surface is very rough, and direct measurement of the adhesion of single micro-particles on surfaces with roughnesses greater than the particle diameter can be difficult. In this work cotton films were successfu...

Phase contrast and epifluorescence microscopy were utilized to monitor morphological changes in human astrocytoma cells during a time-course exposure to single-walled carbon nanotube (SWCNT) conjugates with different surfactants and to investigate sub-cellular distribution of the nanotube conjugates, respectively. Experimental results demonstrate that cytotoxicity of the nanotube/surfactant con...

Washing is one of the common technologies in the chlorinated organic pollution site repair, surfactant adding would help washing more chlorinated organics pollution, but it also can be dissolved in eluent with the chlorinated organic together, and increase the difficulty of the eluent treatment. In this text, three surfactants, anionic surfactant (sodium dodecyl benzene sulfonate, SDBS), cation...

We present spectroscopic analyses of 17 faint blue stars in the globular cluster NGC 6752, using optical and UV spectrophotometric data and intermediate resolution optical spectra. Effective temperatures, surface gravities, and helium abundances of the stars are determined and compared to theoretical predictions. All stars are helium deficient by factors ranging from 3 to more than 100, indicat...

This research aimed to study the effects of individual components on physicochemical properties systems composed surfactants, polymers, oils, and electrolytes in order maximize recovery efficiency kerosene while minimizing impact environment human health. Four independent factors, namely anionic surfactant sodium dodecylbenzene sulfonate (X1) (SDBS), oil (X2) (kerosene), water-soluble polymer p...

Recently a new class of hot subluminous stars strongly enriched in C and O have been discovered (CO-sdOs). These show abundances very similar to those observed PG1159 but at lower temperatures. Moreover, it has recently suggested that enrichment might be the key ingredient driving pulsations He-rich subdwarf (He-sdBVs). Here we argue these two types rare can explained by variant one main channe...

In this study, the urea-formaldehyde (UF)-tung oil solution of phenolic amide (PA) microcapsules to realize anti-fouling and anti-corrosion integration was synthesized by in situ polymerization method. The compounds structures were optimized investigating six kinds different emulsifiers. results showed that high-core-content narrow-particle-size-distribution could be with sodium dodecyl benzene...
