The interaction of poly(methacrylic acid) (PMAA) brushes with oppositely charged surfactants has been studied as a function of the polymer brush graft density, the surfactant concentration, and the surfactant alkyl chain length at neutral pH. The changes in the degree of dissociation of the polyacid alpha and in the amount of surfactant uptake beta were determined from infrared and multiple-angle ellipsometry measurements, respectively. The brush shrinks already strongly at a surfactant concentration of around 10-5 mol L-1, despite that the surfactant uptake in this regime is still low. A strong surfactant uptake sets in only above a critical concentration, which is slightly below the critical micelle concentration (cmc) of the respective surfactant. A comparison of dissocation a and surfactant uptake beta reveals that the surfactant is not exclusively bound electrostatically by an exchange of the carboxylic acid protons for surfactant ions, but also through hydrophobic interactions. The influence of surfactant concentration, alkyl chain length, and graft density on the complexation behavior is studied.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1120-02-1 is helpful to your research. Electric Literature of 1120-02-1

A series of 1,10-phenanthroline derivatives were used as supporting ligands for copper-catalyzed Ullmann reaction in neat water. The catalytic system based on 4,7-dihydroxy-1,10-phenanthroline has demonstrated the promising catalytic performances for aryl bromides. The catalytic system was applicable to a wide scope of substrates, high catalytic activity and selectivity were observed for the reactions of electron-deficient, electron-rich, and heterocyclic aryl bromides with imidazoles containing different steric hindrance. The superior promoting effect of 4,7-dihydroxy-1,10-phenanthroline is attributed to its water solubility under the basic conditions. You can?t hold back the power of water: pH-Responsive 4,7-dihydroxy-1,10-phenanthroline exhibits an excellent promoting effect in copper-catalyzed Ullmann cross-coupling reaction of aryl bromides and imidazoles with different steric hindrance in neat water.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 3922-40-5, you can also check out more blogs about3922-40-5

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1119-97-7, name is MitMAB, introducing its new discovery. Formula: C17H38BrN

The anaerobic biodegradability and toxicity to methanogenic gas production of different alkyl chain length homologs of quaternary ammonium based surfactants were examinated. Two series of these cationic surfactants were selected: alkyl trimethyl ammonium and alkyl benzyl dimethyl ammonium compounds. A simple anaerobic gas production test containing municipal digester solids as a source of anaerobic bacteria was used. Under the applied methanogenic conditions, the cationic surfactants tested showed a very poor primary biodegradation and no evidence of any extent of ultimate biodegradation was observed. The toxicity of quaternary ammonium based surfactants to methanogenic gas production decreased with increasing the alkyl chain length.

Cyclic voltammetry investigation has been performed for the binary mixtures of tetradecyltrimethylammonium bromide (TTAB), hexadecyltrimethylammonium bromide (HTAB), and polyoxyethylene(23)laurylether (Brij 35), with triblock polymers, Pluronic L64 and F127, by using 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) as an electroactive probe at 25C. A variation in the peak current versus the total concentration of surfactant allowed us to evaluate the critical micellar concentration (cmc) and related parameters from regular solution theory along with the diffusion coefficient of the electroactive species. A variation in the micellar mole fraction of the ionic component suggests that the mixed micelles are rich in triblock polymer component in the ionic surfactant rich region of the mixture and vice versa. The regular solution interaction parameter (beta) indicates the formation of mixed micelles due to synergistic interactions which have been found to be more intense in the combinations of F127 rather than that of L64.

In this study, the gemini surfactants of the alkanediyl-alpha-omega- bis(alkyl dimethyl ammonium) dibromide type, on the one hand, with different alkyl groups containing m carbon atoms and an ethanediyl spacer, referred to as ”m-2-m” (m = 10, 12 and 16) and, on the other hand, with n-C16 alkyl groups and different spacers containing s carbon atoms, referred to as ”16-s-16” (s = 2, 6, 10 and Ar (8)) have been synthesized, purified and characterized. The critical micelle concentration (CMC), micelle ionization degree (alpha) and Gibbs free energy of micellization (DeltaGmic) of these surfactants and the monomeric cationic surfactants DTAB and CTAB have been determined by means of electric conductivity measurements. In addition, the temperature dependence of the CMC was determined for the 10-2-10 gemini surfactant. The CMCs of the gemini surfactants are found to be much lower than those of the corresponding monomeric surfactants and the effect of the hydrophobic alkyl chain length is more important than that of the spacer. The CMC of 16-s-16 passes through a maximum of (or around) s = 6 and then decreases for s = 10. The presence of a maximum CMC is explained by the contribution of a change of conformation of the surfactant with increasing spacer chain length. The changes of a with s and m are found qualitatively similar to those found for CMC values. The values of DeltaGmic are more negative for the dimers than for the monomers and also change with an increasing spacer carbon number, as CMC values do. The thermodynamic parameters of micellization indicate that the micellization of 10-2-10 is enthalpy driven. AOCS 2011.

Feasibility of implementing a DEC-fortified (DEC at 0.2% w/w and iodine) salt strategy to hasten elimination of diurnally sub-periodic Wuchereria bancrofti (DspWB) from the lone foci in Nancowry islands, Nicobar district, India, was assessed. This is a two-arm community-based study: one arm (12 villages, population 2936) received double fortified salt along with annual mass drug administration (MDA) of DEC plus albendazole (DEC-salt+MDA-arm), and another (14 villages; population 4840) received MDA under the National Filaria Elimination Programme. DEC salt was distributed on camp mode supplemented by door delivery. Monthly survey was carried out in fixed and random households to assess the coverage, usage of DEC salt and DEC content. The impact on prevalence of mf at community level and antigenaemia among children was assessed. A total of 21 metric tonnes of free-flow DEC salt manufactured by Tamil Nadu Salt Corporation, India, was distributed for 1 year. In the DEC-salt+MDA-arm, > 90% of the households received and used the DEC salt. DEC was within therapeutic range (0.2?0.32% w/w) in the samples collected from kitchens. Community mf prevalence reduced from 2.27 to 0.14% in the DEC-salt-arm (< 1% in all the villages) and 1.26 to 0.74% (> 1% in 4 out of 14 villages) in the MDA-arm. Ag prevalence reduced to zero from 1.0 (DEC-salt+MDA-arm) and 6.3% (MDA-arm) in 2?3 years old, 1.2 and 3.6% from 2.9 in the DEC-salt-arm and 4.5% in the MDA-arm among 6?7 years old. It was feasible to deliver DEC-fortified salt covering > 90% of the households with compliance reaching the elimination target in the islands.

Cyanide ions are shown to interact with lanthanide complexes of phenacylDO3A derivatives in aqueous solution, giving rise to changes in the luminescence and NMR spectra. These changes are the consequence of cyanohydrin formation, which is favored by the coordination of the phenacyl carbonyl group to the lanthanide center. These complexes display minimal affinity for fluoride and can detect cyanide at concentrations less than 1 mum. By contrast, lanthanide complexes with DOTAM derivatives display no affinity for cyanide in water, but respond to changes in fluoride concentration.
