The effect of propylene glycol (PG), its monoalkyl ethers and esters on the micellar behavior of a cationic surfactant tetradecyltrimethylammonium bromide (TTAB) in aqueous solution was examined by employing electrical conductivity and small angle neutron scattering (SANS) technique. From conductivity measurements critical micelle concentration (CMC) and degree of counter ion dissociation (alpha) were evaluated. PG and propylene glycol monomethyl ether (PGMME) delayed micelle formation while propylene glycol monobutyl ether (PGMBE) propylene glycol monomethyl ether acetate (PGMMEA) and propylene glycol diacetate (PGDA) favored the process at studied concentrations. SANS data revealed the effect of all these additives for 100 mM TTAB; decrease in micelle size and aggregation number (Nagg) was observed. Results are discussed in terms of effect of additives on water structure and solvent properties and correlated with structure of additives and their octanol-water partition co-efficient values (log Po/w).

A highly sensitive and simple colorimetric strategy for Hg2+ detection is introduced based on anti-aggregation of gold nanoparticles (AuNPs). 2-Mercaptobenzothiazole (MBT) can cause the aggregation of AuNPs due to strong covalent Au-S bond formation resulting in color change from red to blue. However, the presence of Hg2+ led the AuNPs to remain in the dispersed state because MBT prefers to interact with Hg2+ rather than AuNPs. Based on the anti-aggregation mechanism, Hg2+ can be detected by observing the color change of AuNPs solution containing MBT. The minimum detectable quantity is 0.1 muM by the naked eyes, and the limit of the detection (LOD) is 6.0 nM by UV-vis spectroscopy with the linear range from 0.05 to 1.0 muM. Furthermore, the developed detection system is also environmental-friendly and inexpensive, which has been successfully used in lake water and milk powder samples detection.

Using a cationic trimeric surfactant [C14H29N+(CH3)2(CH2)2N+(CH3)(C14H29) (CH2)2N+(CH3)2C14H29]·3Br- (C14-14-2-14), with a short spacer group (s = 2) as structure-directing agent and sodium silicate as precursor, high quality, ordered two-dimensional (2D) hexagonal mesoporous silica was prepared through the S+I- route (S = surfactants, I = precursor). The samples were characterized by small-angle X-ray diffraction, transmission electron microscopy (TEM) and N2 adsorption-desorption. Results showed that the pore structure belonged to 2D hexagonal structure with space group P6mm. The mesoporous silica possessed uniform pore arrays, which pore size was about 3.0 nm. The Brunauer-Emmet-Teller (BET) surface area was up to 1000 m2/g. With the decrease of hydrothermal temperature and of the molar ratio of sodium silicate to C14-2-14-2-14, the mesostructure of silica became more ordered. Compared with tetradecyltrimethylammonium bromide (TTAB), which could be taken as the monomer of C14-2-14-2-14, and it was also used as structure-directing agent to synthesize mesoporous silica, C14-2-14-2-14 was a good structure-directing agent for the synthesis of mesoporous materials due to its strong assembly ability.

Investigations of intermolecular interactions are of great interest and many studies in this field focus on the use of theoretical computational chemistry. Commonly the systems of interest comprise molecules with hundreds of atoms, limiting the use of ab initio theoretical methods. In order to investigate the accuracy of different quantum chemical methods, a systematic study was carried out involving 15 inclusion complexes of alpha-cyclodextrin and 28 complexes of beta-cyclodextrin. The accuracy of semiempirical methods in geometry prediction was evaluated in comparison to crystallographic data, with AM1 and PM3 showing the best results. Subsequently, the accuracy of semiempirical methods in predicting both geometry and interaction energy was studied using the results of DFT calculation as reference, with and without dispersion correction. The best method was B3LYP/6-31G(d,p) with D3 correction, followed by PM6 with D3 correction with similar accuracy. However, as the DFT method require a high computational cost for large systems, PM6-D3 is the method recommended for the systems studied here. The main conclusion is the need to develop a semiempirical method capable of correctly describing the interaction energy, which must correspond to an accurate geometry.

Cyclic voltammograms (CVs) of C60 films and C60 embedded in cast films of triple-tailed cationic surfactant solutions and salt-free zero-charged cationic/anionic (catanionic) surfactant vesicles on glassy carbon electrode in a typical room-temperature ionic liquid (RT-IL), 1-n-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]), were examined. CVs show typically electrochemical oxidation and reduction. The salt-free zero-charged catanionic surfactant bilayer vesicles were determined by freeze-fracture transmission electron microscopy (FF-TEM) images and small-angle X-ray scattering (SAXS) measurements. The cast films of the salt-free zero-charged catanionic surfactant vesicles incorporated C 60 molecules were employed to study the electrochemical properties in RT-ILs, which would open new fields for the bulk electronic properties of fullerenes or their derivatives in ionic liquids.

It is widely accepted that particles stabilize flotation froths and that stable froths result in improved flotation performance. Predicting the effect of particle addition on froth stability is, however, challenging. Furthermore, there is currently no technique that allows the prediction of the effect of different flotation reagents on froth stability, without carrying out froth stability experiments. In this study, we use the maximum bubble pressure technique to measure the surface tension with and without particles, over a range of surfactant concentrations, and compare the results to froth stability measurements. The results show a clear link between surface tension and froth stability, with conditions that yield lower surface tension giving higher froth stability. The addition of particles lowers surface tension, and increases froth stability. This work shows, for the first time, the explicit link between surface tension and froth stability in particulate systems. We propose that the maximum bubble pressure technique can be used to predict the effect on froth stability of changing combinations of particles and reagent type and dosage in a rapid, reproducible system.

Catalase is one of the firsts in every realm of biological sciences. At the same time it also has a number of unusual features. It has one of the highest turnover numbers of all enzymes. It is essential for neutralizing the noxious hydrogen peroxide both in the nature and the various industries such as dairy, textile and pharmaceutics. It also has the merit of being one of the first protein crystals to be isolated. Ironically its three-dimensional structure was discerned some forty years later. However through the times this senile enzyme has continued to intrigue the scientists by surprising facts and phenomena, such as peculiar interweaving of subunits and remarkable thermal stability. It is also known for suicide inactivation by its own substrate. Catalase is known to be implicated in various medical scenarios and its levels have served as a marker in that capacity. It has even been incorporated into several pharmaceuticals. This review strives to clarify these perspectives. It also draws attention to the biophysical contributions offered by thermodynamics and kinetics in these discoveries. The ultimate aim of this review, however, is to state that the venerable catalase will continue to bewilder us with its mysteries well into the twenty-first century.

Synthetic Route of 1119-97-7, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1119-97-7, Name is MitMAB, molecular formula is C17H38BrN.

The interaction between ceftriaxone sodium trihydrate (CFT) drug and surfactants such as tetradecyltrimethylammonium bromide (TTAB), Triton X-100 (TX-100), and Tween-80 (TW-80) was studied under various conditions by using three different physico-chemical methods. CFT is used for the treatment of lung infections, urinary bladder, bone, joint, gonorrhea, meningitis, etc., depending on the bacterial disease. Different parameters such as critical micelle concentration (cmc), various thermodynamic parameters for drug-TTAB aqueous mixtures in an ethanol solvent, etc., have been measured. The varying cmc value of TTAB with the addition of CFT in the TTAB solution signifies the existence of interaction between TTAB and CFT. This interaction and the cmc values of mixtures of drug and TTAB, depend upon the employed concentration of alcohols and the system temperature. Negative values of the standard free energy of micellization (DeltaGo m), were obtained for all cases; this indicates the spontaneous nature of the currently employed system of drug and surfactant mixtures. Parameters such as heat capacity (DeltaCp.m.) and various transfer energies were also evaluated and are discussed. In the case of the cloud point (CP) method the phase separation of TX-100 in an aqueous system was intensified in the presence of CFT. The standard free energy of clouding (DeltaGo c), for the (CFT-TX-100) system was evaluated and found to be positive; this indicates the non-spontaneous characteristic of this clouding action. For the system of CFT-TW-80 mixtures, the value of the binding constant (Kb) is dependent on temperature, and the types of solvent of different composition in both aqueous and alcoholic mediums. Therefore, hydrogen bonding and electrostatic interactions are important due to the binding interaction between CFT and TW-80.
