Title: The effects of cetyltrimethylammonium bromide surfactant on alumina modified zinc oxides

Abstract

Highlights: • Synthesis of novel ZnO−Al{sub 2}O{sub 3} oxides in the presence of CTAB surfactant. • Determination of the structural, surface and optical properties. • Nanocrystalline, high-surface area ZnO−Al{sub 2}O{sub 3} oxides. • ZnO-Al{sub 2}O{sub 3} materials of different gap energy. - Abstract: Novel alumina modified zinc oxide materials were prepared by co-precipitation method in the presence of different amounts of cetyltrimethylammonium bromide (CTAB) surfactant. X-ray diffraction, {sup 27}Al magic-angle spinning Nuclear Magnetic Resonance Spectroscopy, and transmission electron microscopy studies evidenced formation of 10–15 nm zinc oxide nanoparticles in the presence of the small amounts of surfactant. Amorphous alumina and zinc aluminate phases of different coordination environment of Al sites were identified. An increase of surfactant concentration led to the elongation of nanoparticles and changes of the nature of hydroxyl groups. Precipitation in the high CTAB concentration conditions facilitated formation of mesoporous materials of high specific surface area. The materials were composed of very small (2–3 nm) zinc aluminate spinel nanoparticles. High concentration of CTAB induced widening of band gap energy.

  • This paper reports on the characterization and preliminary comparison of gold nanoparticles of differing surface modification and shape when used as extrinsic Raman labels (ERLs) in high-sensitivity heterogeneous immunoassays based on surface enhanced Raman scattering (SERS). ERLs are gold nanoparticles coated with an adlayer of an intrinsically strong Raman scatterer, followed by a coating of a molecular recognition element (e.g., antibody). Three types of ERLs, all with a nominal size of {approx}30 nm, were fabricated by using spherical citrate-capped gold nanoparticles (sp-cit-Au NPs), spherical CTAB-capped gold nanoparticles (sp-CTAB-Au NPs), or cube-like CTAB-capped gold nanoparticles (cu-CTAB-Au NPs) as cores. The performancemore » of these particles was assessed via a sandwich immunoassay for human IgG in phosphate buffered saline. The ERLs fabricated with sp-CTAB-Au NPs as cores proved to be more than 50 times more sensitive than those with sp-cit-Au NPs as cores; the same comparison showed that the ERLs with cu-CTAB-Au NPs as cores were close to 200 times more sensitive. Coupled with small differences in levels of nonspecific adsorption, these sensitivities translated to a limit of detection (LOD) of 94, 2.3, and 0.28 ng/mL, respectively, for the detection of human IgG in the case of sp-cit-Au NPs, sp-CTAB-Au NPs, and cu-CTAB-Au NPs. The LOD of the cu-CTAB-Au NPs is therefore {approx}340 times below that for the sp-cit-Au NPs. Potential applications of these labels to bioassays are briefly discussed.« less
  • In this paper, we have investigated the chemical bonding interaction of S in a CTAB (cetyltrimethylammonium bromide, CH 3(CH 2) 15N +(CH 3) 3Br )-modified sulfur–graphene oxide (S–GO) nanocomposite used as the cathode material for Li/S cells by S K-edge X-ray absorption spectroscopy (XAS). The results show that the introduction of CTAB to the S–GO nanocomposite and changes in the synthesis recipe including alteration of the S precursor ratios and the sequence of mixing ingredients lead to the formation of different S species. CTAB modifies the cathode materials through bonding with Na 2S x in the precursor solution, which ismore » subsequently converted to C–S bonds during the heat treatment at 155 °C. Moreover, GO bonds with CTAB and acts as the nucleation center for S precipitation. Finally, all these interactions among S, CTAB, and GO help to immobilize the sulfur in the cathode and may be responsible for the enhanced cell cycle life of CTAB–S–GO nanocomposite-based Li/S cells.« less

  • The solubility of water in water-in-oil microemulsions stabilized by cetyltrimethylammonium (CTA) has been investigated as a function of the nature of the surfactant counterion (bromide; CTAB/chloride; CTAC), the composition of the oil (chloroform and chloroform/heptane mixtures), the salinity of the droplets, and the nature of the salt employed to modify it. Changing the composition of the oil from neat chloroform to a 500% mixture with heptane produces an increase of the water solubility in the microemulsions stabilized by CATB and decreases it in the CTAC microemulsions. Strong alterations of the solubility of water were found to occur upon mixing ofmore » the surfactants. Solubility increases abruptly on going from either CTAC- or CTAB-stabilized microemulsions to mixtures of both surfactants, reaching a maximum at CTAC mole fractions of 0.5 and 0.4 for solutions of the surfactants in chloroform and chloroform/heptane, respectively. Mixtures of CTAC and CATB in a solvent comprising 500% chloroform/heptane show a different behavior. In this system, water solubility continuously decreases when the CTAC/CTAB ratio increases. Solubility increases with salinity in the CTAC-stabilized microemulsions and decreases in the CTAB-stabilized microemulsions. Nevertheless, the magnitude of the effects observed is dependent on the nature of the salt employed to modify the salinity of the droplets. The results obtained are explained in terms of the model of Shah and coworkers by considering that, due to the stronger binding of bromide than of chloride to the surfactant heads at the micellar interface, water solubility in solutions of CTAB or CTAC in chloroform is determined by different factors: the curvature of the surfactant film (CTAB) and the interaction between droplets (CTAC).« less
