Ovalbumin, pertussis toxin, aluminum hydroxide, MgSO4, NaH2PO4, KCl, NaHCO3, NaCl, glucose, sucrose, CaCl2, Tween 80, dimethyl sulfoxide, pancuronium bromide, sodium cyanide, trypsin, Ham's F12, Ki16425, and ethanol were purchased from Sigma-Aldrich (Sigma-Aldrich, Oakville ON).
Various surfactants were used in the electrode modification: dihexadecyl hydrogen phosphate, cetyltrimethylammonium bromide, sodium dodecyl sulfate and Triton X-100.
Briefly, a GNPs growth system consisted of designated concentrations of hydrogen tetrachloroaurate, cetyltrimethyl ammonium bromide, sodium citrate, and phosphate buffer was designed, followed by the addition of 1 mL different level of test samples.
When fixing a sample, synthetic resin may be substituted by halide salts (i.e. potassium bromide, sodium chloride or silver chloride etc).
Gnanam and Rajendran [16] synthesized nanocrystalline tin oxide powders of about 8 to 13 nm in size using different surfactants such as cetyltrimethyl ammonium bromide, sodium dodecyl sulphate, and polyethylene glycol via hydrothermal reaction at 160°C for 12 h and studied their structural and photoluminescence properties.
Berberine, ethidium bromide, sodium pyruvate, uridine, and L-nitroarginine methyl ester (L-NAME) were obtained from Sigma-Aldrich Inc. (St . Louis MO).
Enthalpies of solution were measured for tetraphenylphosphonium bromide (Ph4PBr), sodium tetraphenylborate (NaBPh4) and sodium bromide (NaBr) in mixtures of N,N-dimethylformamide (DMF) and water over the whole composition range at 298.15 K. Single ion enthalpies of transfer were calculated with a number of assumptions.
The β-galactosidase activity was determined as described in Zhang and Bremer (1995), with the following modifications: hexadecyltrimethylammonium bromide and sodium deoxycholate were excluded from the substrate solution and the concentration of dibasic sodium phosphate in the permeabilization solution was 100 mM.
Silver nitrate (AgNO3), tetraethylorthosilicate (TEOS), 3-aminopropyltrimethoxysilane (APTS), cetyltrimethyl ammonium bromide (CTAB), sodium borohydride (NaBH4), 1-ethyl-3- 3-dimethyl aminopropyl)-carbodiimide (EDC), poly(sodium-4-styrenesulfonate) (PSS), and ascorbic acid were obtained from J & K Chemical Limited (China).
Novel reservoir engineering displacement fluids (cetyltrimethylammonium bromide and sodium salicylate in water) are examined as candidates for proppant placement during fracturing.
The presence of NaCl, AlCl3, cetyltrimethyl ammonium bromide and sodium dodecylsulfate observed to cause high colloidal stabilities of the nanocomposite dispersions by reaching to zeta-potential values of ζ > + 30 mV and ζ < − 30 mV.
