Acidic hydrolyses of some carbon and nitrogen substituted hydroxamic acids (R-C(O) N(OH)R’, R = CH3, R’=H; R=C6H5, R’ = H; R = C6H5, R’ = C6H5, R = C6H5, R’ = 4-CH3-C6H4) have been studied at 55 C in mixed micellar solution of surfactants (cationic – cationic, cationic-nonionic and anionic – nonionic). The results indicate that addition of nonionic surfactant to an acid solution of anionic surfactant (SDS) strongly decreases the observed rate constant. In other mixed micellar systems inhibition has been observed. Binding constants and rate constants for the reaction in the micellar pseudophase, obtained from the kinetic analysis, have been reported. The inhibition effects depend on the hydrophobic chain length of the surfactants and the hydrophobicity of the substrate.

On-column complexation of metal ions with 2,6-pyridinedicarboxylate (2,6-PDC) to form anionic complexes enabled their separation by capillary zone electrophoresis with direct UV detection at 214 nm. Nine metal ions, Cu2+, Zn2+, Ni2+, Cd2+, Mn2+, Pb2+, Fe3+, Al3+ and Ca2+, were determined in less than 7 min using10 mM 2,6-PDC solution containing 0.75 mM tetradecyltrimethylammonium bromide at pH 4.0. Satisfactory working ranges (20-300 muM), detection limits (3-10 muM) and good repeatability of the peak areas (RSD 2.1-4.2%, n=5) were obtained using hydrodynamic injection (30 s). The proposed method was used successfully for the determination of Mn2+, Fe3+, Al3+ and Ca2+ in groundwaters.

The interaction between bis(hexadecyldimethylammonium)hexane dibromide (16-6-16), bis(tetradecyldimethylammonium)hexane dibromide (14-6-14), their conventional counterparts cetyltrimethylammonium bromide (CTAB) and tetradecyltrimethylammonium bromide (TTAB) with polyvinylpyrrolidone (PVP) was investigated using the conductivity technique. The results show that gemini surfactants interact strongly with PVP as compared to conventional surfactants. The results also reveal that the surfactants with shorter hydrocarbon chain interact weakly as those of longer hydrocarbon chain. The interactions of 16-6-16 and 14-6-14 and their conventional counterparts with PVP were also studied using dynamic light scattering (DLS) measurements. We have also highlighted the effect of surfactant-polymer interactions on the dispersion force in the solution. Critical aggregation concentration (cac) and critical micelle concentration (cmc) were obtained using the conductivity data. The degrees of micelle ionization and free energies associated with aggregation, micellization, and transfer have also been evaluated and discussed.

Neuronal dynamin I plays a critical role in the recycling of synaptic vesicles, and thus in nervous system function. We expressed and purified dynamin I to explore potentially clinically useful endocytosis inhibitors and to examine the mechanism of their action. We estimated the IC50 of nineteen psychotropic drugs for dynamin I. The IC50 values of two selective serotonin reuptake inhibitors (sertraline and fluvoxamine) were 7.3±1.0 and 14.7±1.6 muM, respectively. Kinetic analyses revealed that fluvoxamine is a noncompetitive inhibitor of dynamin I guanosine triphosphatase (GTPase) with respect to guanosine 5?-triphosphate (GTP) and a competitive inhibitor with respect to L-phosphatidylserine (PS). Fluvoxamine may compete with PS for binding to the pleckstrin homology domain of dynamin I. On the other hand, sertraline was a mixed type inhibitor with respect to both GTP and PS. Our results indicate that sertraline and fluvoxamine may regulate the transportation of neurotransmitters by modulating synaptic vesicle endocytosis via the inhibition of dynamin I GTPase.

The method for separation and determination of several di- and tricarboxylic acids, including oxalic, malic, tartaric and citric acids (OX, MA, TA and CI), found in fruit juices by capillary zone electrophoresis with amperometric detection at a copper electrode was developed. Based on cyclic voltammetry (CV) experiments, the detection mechanism for the analytes at a copper electrode was proved to be the formation of complexes between di- and tricarboxylic acids and Cu(II) ion on the electrode surface. Separation was carried out in a pH 6.2 phosphate buffer solution (PBS) containing 0.4mmol/l cetylpridinium bromide (CPB) and 20mmol/l beta-cyclodextrin (beta-CD) as an electro-osmotic flow (EOF) modifier to reverse the direction of the EOF and a complexing reagent for CPB to improve the separation, respectively. At the working potential of 0.12V (versus SCE), the calibration curves for the analytes were linear with about three orders of magnitude and the detection limits (S/N=3) for them were between 4 and 8fmol. By the method developed here, di- and tricarboxylic acids in four fruit juices, apple, grape, pear and orange juices, were successfully separated and determined.

The binding and rotational properties of an excited-state intramolecular proton transfer (ESIPT) fluorophore, 2,2a¿²-bipyridine-3,3a¿²-diol, BP(OH)2 has been investigated in alkyltrimethylammonium bromide containing (CnTAB, n = 12, 14, and 16) micelles and alkyltrimethylammonium bromide/cholesterol (CnTAB (n = 14 and 16)/cholesterol) forming vesicles using fluorescence-based spectroscopy techniques. The formation of thermodynamically stable unilamellar self-assemblies of alkyltrimethylammonium bromide/cholesterol are characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM) measurements. Individually, aqueous solutions of all these alkyltrimethylammonium bromide form micelles after certain surfactant concentration (critical micelle concentration, cmc) of surfactant, whereas cholesterol molecules are insoluble in water. But with the variation of the cholesterol-to-surfactant molar ratio (Q = [cholesterol]/[surfactant]), uniform distribution of vesicular aggregates in aqueous solution can be obtained. The micelle-to-vesicle transition of surfactant solution upon addition of cholesterol also influences the steady state emission profile, fluorescence lifetime, and rotational dynamics of BP(OH)2 molecule. The diketo tautomer of BP(OH)2 molecule gets stabilized as the concentration of surfactant increases in aqueous solution. Fluorescence lifetime and rotational time constant of the BP(OH)2 molecule are also influenced by the variation of alkyl chain length of surfactant molecule. The emission quantum yield (I¿) is also found to be sensitive with surfactant concentration, variation in chain length of surfactants, and it saturates after the cmc of surfactants. The rigid and restricted microenvironment of vesicle bilayer enhance the lifetime and also rotational relaxation of BP(OH)2 significantly. The rotational behavior of BP(OH)2 in surfactant/cholesterol self-assemblies is also explained by using analytical parameters related to time-resolved anisotropy following two-step process and wobbling in a cone models.

Achieving mastery over the synthesis of metal nanocrystals has emerged as one of the foremost scientific endeavors in recent years. This intense interest stems from the fact that the composition, size, and shape of nanocrystals not only define their overall physicochemical properties but also determine their effectiveness in technologically important applications. Our aim is to present a comprehensive review of recent research activities on bimetallic nanocrystals. We begin with a brief introduction to the architectural diversity of bimetallic nanocrystals, followed by discussion of the various synthetic techniques necessary for controlling the elemental ratio and spatial arrangement. We have selected key examples from the literature that exemplify critical concepts and place a special emphasis on mechanistic understanding. We then discuss the composition-dependent properties of bimetallic nanocrystals in terms of catalysis, optics, and magnetism and conclude the Review by highlighting applications that have been enabled and/or enhanced by precisely controlling the synthesis of bimetallic nanocrystals.

Recent developments in the field of water-soluble polymers aimed at enhancing the aqueous solution viscosity are reviewed. Classic and novel associating water-soluble polymers for enhanced oil recovery (EOR) applications are discussed along with their limitations. Particular emphasis is placed on the structure-property correlations and the synthetic methods. The observed rheological properties are conceptually linked to the polymer chemical structure (1) and topology (2). In addition, the influence of external parameters, e.g. temperature, pH, salt, and surfactant, on the rheological behavior is reviewed. Progress booked in deeper understanding of the structure-property relationship is thoroughly discussed. Furthermore, a critical overview of the synthetic methods as well as of the solution properties of these polymers is provided. In this respect the influence of “internal” (i.e. chemical structure) and “external” (vide supra) factors on these properties provide a conceptual toolbox for the rationalization of the response of water-soluble polymers to external stimuli. In turn, such rationalization constitutes the basis for the design of new polymeric structures for EOR applications.

In this Letter, we show that the shape of a freezing drop of water can be sensitive to the presence of impurities. We measure the tip angle of water drops frozen on a cold plate. The fine changes in the tip angle are robustly captured by our image analysis method, which shows a deviation from that of pure water in solutions with salt (NaCl), polymer polyethylene glycol, and surfactant tetradecyltrimethylammonium bromide starting at concentrations of 10 – 6, 10 – 4, and 10 – 6 M, respectively. The method could be adapted into a portable water purity tester, but this work also highlights the complexity of water freezing as it is influenced by trace concentrations of impurities.
