Layer-by-layer assembly of polymersomes and polyelectrolytes on planar surfaces and microsized colloidal particles
Published in Journal of Colloid and Interface Science
Abstract Hybrid polyelectrolyte multilayer systems were fabricated on top of planar surfaces and colloidal particles via layer by layer (LbL) assembly of polystyrene sulphonate (PSS) and polybenzyl methacrylate-block-poly(dimethylamino)ethyl methacrylate (PBzMA-b-PDMAEMA) polymersomes. Polymersomes were prepared by self assembly of PBzMA-b-PDMAEMA ...
Manipulating interactions between functional colloidal particles and polyethylene surfaces using interfacial engineering...
Published in Journal of Colloid and Interface Science
Abstract The purpose of this study was to examine the interaction between lipid droplets and polyethylene surfaces, representative of those commonly used in food packaging. Lipid droplets with various surface charges were prepared by homogenizing corn oil and water in the presence of surfactants with different electrical characteristics: non-ionic ...
Adsorption analysis of nitrophenol isomers on silver nanostructures by surface-enhanced spectroscopy
Published in Journal of Colloid and Interface Science
Abstract SEIRA, SERS, TPD and DFT were used to study 4-nitrophenol (4NP), 3-nitrophenol (3NP) and 2-nitrophenol (2NP) adsorption on nanoscale silver films/powder. SERS and DFT demonstrated that 4NP adsorbed as the 4-nitrophenolate ion. SEIRA results revealed that a 4NP multilayer condensed differently using deposition solvents with and without pola...
A facile method for preparation of gold nanoparticles with high SERS efficiency in the presence of inositol hexaphosphat...
Published in Journal of Colloid and Interface Science
Abstract This paper described a facile method for preparation of gold nanoparticles with high efficient SERS activity within short reaction time in the presence of an environmentally benign and low-cost reagent named inositol hexaphosphate (IP 6). IP 6 acted as a tunable cross-linker to obtain a suitable separation (about 2 nm) between the neighbor...
Surface modification on a hyper-cross-linked polymeric adsorbent by multiple phenolic hydroxyl groups to be used as a sp...
Published in Journal of Colloid and Interface Science
Abstract A hyper-cross-linked polymeric adsorbent functionalized with multiple phenolic hydroxyl groups HJ-03 was prepared in this study and its adsorptive characteristics for p-nitroaniline from aqueous solution were studied as compared with Amberlite XAD-4. The adsorption of p-nitroaniline was sensitive to the solution pH and the maximum adsorpti...
Hot-injection synthesis of highly luminescent and monodisperse CdS nanocrystals using thioacetamide and cadmium source w...
Published in Journal of Colloid and Interface Science
Abstract Thioacetamide (TAA) has served as an excellent sulfur source to react with cadmium stearate to controllably produce highly luminescent and monodisperse CdS nanocrystals through the hot-injection method in dodecylamine solvent. The kinetics and thermodynamics of nucleation/growth of CdS nanocrystals, as well as their optical properties are ...
Diffusiophoresis of a sphere along the axis of a cylindrical pore
Published in Journal of Colloid and Interface Science
Abstract The diffusiophoresis of a charged spherical particle along the axis of an uncharged cylindrical pore filled with an electrolyte solution is analyzed theoretically. The influence of chemiphoresis, which includes two types of double-layer polarization, and that of electrophoresis arising from the difference in the diffusivities of the ionic ...
Micellization and micellar growth of alkanediyl-α,ω-bis(dimethyldodecylammonium bromide) surfactants in the presence of ...
Published in Journal of Colloid and Interface Science
Abstract Micellization and micellar growth of cationic dimeric surfactants of the alkanedyil-α,ω-bis(dimethyldodecylammonium) bromide type, 12- s-12,2Br − ( s = 3, 4, 6), in the presence of various amounts of 1-butanol, 1-pentanol, and 1-hexanol have been investigated. The influence of the nature and concentration of alcohol on the cmc, on the mice...
Predictive synthesis of ordered mesoporous silica with maltoside and cationic surfactants based on aqueous lyotropic pha...
Published in Journal of Colloid and Interface Science
Abstract Self-assembled nonionic alkyl glycoside surfactants are of interest for creating functional adsorption and catalytic sites at the surface of mesoporous sol–gel-derived materials, but they typically impart poor long-range order when they are used as pore templates. Improved order and control over the functional site density can be achieved ...
