In this work, we studied nonlinear dynamics and optical limiting (OL) effects of pulse trains in zinc porphyrins meso-tetrakis methylpyridiniumyl (Zn2+TMPyP) sulfonatophenyl (Zn2+TPPS) porphyrin J-aggregates. The environments were selected as aqueous solutions micelles sodium dodecyl sulfate (SDS) cetyltrimethyl ammonium bromide (CTAB). Our numerical results show that both Zn2+TMPyP Zn2+TPPS ar...

We report a facile route to selectively deposit and arrange palladium (Pd) nanoparticles on single-walled carbon nanotubes (SWCNTs) having sub 10 nm diameter by using supramolecular self-assembly of sodium dodecyl sulfate (SDS) as a soft template.

The aim of this study was to investigate the effect of sodium dodecyl sulfate (SDS), citric acid, and hydrogen peroxide (H2O2), alone or in combination, on reducing the population of four foodborne pathogens, including Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus on eggshells. In each series of tests, eight fresh eggs were inoculated with each bact...

Sodium dodecyl sulfate (SDS)-poly(propylene oxide) methacrylate (PPOMA) (of molecular weight M(w) = 434 g x mol(-1)) mixtures have been studied using conductimetry, static light scattering, fluorescence spectroscopy, and 1H NMR. It has been shown that SDS and PPOMA form mixed micelles, and SDS and PPOMA aggregation numbers, N(ag SDS) and N(ag PPOMA), have been determined. Total aggregation numb...

This study investigated calcium sulfate and chitosan on the textural modification microstructure of tofu made from lentils. The addition varying amounts (0–12 mM) (0–1.0%) into lentil milk could affect gel properties lentil-based tofu. properties, including hardness cohesiveness, significantly increased with 12 mM sulfate, exhibiting a slightly discontinuous network structure regular pore netwo...

Surfactants are synthetic organic chemicals that are formulated to have cleansing or solubilisation properties with the development of the industrial economy and increase in population density, surfactants have become one of the most widely disseminated xenobiotics to enter the aquatic environment, creating a serious environmental problem. Principal criterion for the ecological behavior of surf...

Sodium dodecyl sulfate (SDS) self assembles at hydrophobic graphite surfaces forming linear parallel hemicylinders with approximately 5 nm spacing between adjacent hemicylinders. In this paper, we report the effect of cosurfactants on the SDS surface micelle structures. It is known from the literature that cosurfactants influence the relaxation times of bulk phase micelles. Specifically, the re...

This study is to prepare chitosan beads modified with sodium dodecyl sulfate (SDS) effectively remove Cr(III) from an aqueous solution. The characterizations of SDS-chitosan by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform-infrared (FT-IR) and photoelectron (XPS) proved the successful synthesis adsorbent. adsorption on SDS material was investigat...

a simple hydrothermal method was designed for the synthesis of the nanostructure barium phosphonate in presence of cetyltrimethylammonium bromide (ctab) or sodium dodecyl sulfate (sds) as surfactant. ft-ir, edax, xrf, xrd, sem were used to characterize this material. effect of solvent on morphology complex was discussed. thermogr avimetric analysis (tga) shows the existence of porosity and stab...
