Stereocontrolled alpha-Galactosylation under Cooperative Catalysis

A recent discovery of a cooperative catalysis comprising a silver salt and an acid led to a dramatic improvement in the way glycosyl halides are glycosidated. Excellent yields have been achieved, but the stereoselectivity achieved with 2-O-benzylated donors was poor. Reported herein is our first attempt to refine the stereoselectivity of the cooperatively catalyzed galactosylation reaction. Careful optimization of the reaction conditions along with studying effects of the remote protecting groups led to excellent stereocontrol of alpha-galactosylation of a variety of glycosyl acceptors with differentially protected galactosyl donors.

Development and Study of Nanoemulsions and Nanoemulsion-Based Hydrogels for the Encapsulation of Lipophilic Compounds

Biocompatible nanoemulsions and nanoemulsion-based hydrogels were formulated for the encapsulation and delivery of vitamin D-3 and curcumin. The aforementioned systems were structurally studied applying dynamic light scattering (DLS), electron paramagnetic resonance (EPR) spectroscopy and viscometry. In vitro studies were conducted using Franz diffusion cells to investigate the release of the bioactive compounds from the nanocarriers. The cytotoxicity of the nanoemulsions was investigated using the thiazolyl blue tetrazolium bromide (MTT) cell proliferation assay and RPMI 2650 nasal epithelial cells as in vitro model. DLS measurements showed that vitamin D-3 and curcumin addition in the dispersed phase of the nanoemulsions caused an increase in the size of the oil droplets from 78.6 +/- 0.2 nm to 83.6 +/- 0.3 nm and from 78.6 +/- 0.2 nm to 165.6 +/- 1.0 nm, respectively. Loaded nanoemulsions, in both cases, were stable for 60 days of storage at 25 degrees C. EPR spectroscopy revealed participation of vitamin D-3 and curcumin in the surfactants monolayer. In vitro release rates of both lipophilic compounds from the nanoemulsions were comparable to the corresponding ones from the nanoemulsion-based hydrogels. The developed o/w nanoemulsions did not exhibit cytotoxic effect up to the concentration threshold of 1 mg/mL in the cell culture medium.

Performance analysis of a dual component generator-condenser of an absorption heat transformer for water desalination

The purpose of this work is to evaluate the behavior of a novel dual component: generator-condenser (GE-CO) applied to a single-stage absorption heat transformer for water desalination (SAHT-WD) by simple evaporation that operates with a LiBr-H2O mixture. The GE-CO consists of two sections located in the same shell, where desorption and condensation occur simultaneously. The evaluation has been divided into an experimental and a theoretical analysis. The experimental analysis is focused on determining the operating conditions that favor the performance of the GE-CO and the overall SAHT-WD. To estimate the heat transfer coefficients and wetting efficiencies based on the experimental results, a mathematical model that considers variation of the inlet absorption mixture stream, the refrigerant, the heating and cooling water was constructed. The results indicate a good coupling between the GE-CO and the AHT, with maximum values of COP and desalinated water flow of 0.49 and 3.91 x 10(-4) kg/s. The maximum specific desalination rate (SDR) of the AHT-WP was 1.10 x 10(-4) kg/s/kW. Both in the GE and CO, the heat transfers of the film of the absorbent mixture and the refrigerant respectively, limit the heat transfer process.

The electrokinetic properties of cationic surfactants adsorbed on a hydrophobic substrate: effect of chain length and concentration

Electrokinetic (EK) properties, such as the electro-osmotic flow (EOF), are influenced by surfactant adsorption at the solid-liquid interface. With the growing popularity of poly(methyl methacrylate) (PMMA) as the substrate for polymeric-based microfluidics, it is important to understand the effect of surfactants on EOF in these devices. Here, we investigate the effect of surfactant chain length and concentration on the electro-osmotic (EO) mobility induced by three cationic surfactants cetyl trimethylammonium bromide (CTAB), trimethylammonium bromide (TTAB), dodecyl trimethylammonium bromide (DTAB) in PMMA microcapillaries. The EO mobility curve as a function of concentration shows three regimes. First, at very low concentrations below 0.002 mM, the mobility is constant and approximately equal to the value obtained with the surfactant-free electrolyte (1 mM KCl). Next, the EOF reverses and mobility increases linearly with surfactant concentration. Finally, the mobility reaches a plateau at a concentration well below surfactant CMC (0.2-mM CTAB, 0.5-mM TTAB and 2-mM DTAB) and decreases at the vicinity of CMC. Our results show that the rate of change in mobility with respect to concentration is a linear function of chain length and increases with longer-chain surfactants. In addition, we deduce the magnitude of Van der Waals or cohesive energy between the adsorbed alkyl chains from the EO mobility values. For the alkyl trimethylammonium surfactants adsorbed on the hydrophobic surface of PMMA, this energy was found to be 0.114 kT smaller than the reported value for ionic surfactants adsorbed on a hydrophilic surface.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 615-36-1 is helpful to your research. SDS of cas: 615-36-1.

Disruption of Cationic/Anionic Viscoelastic Surfactant Micellar Networks by Hydrocarbon as a Basis of Enhanced Fracturing Fluids Clean-Up

Studies of the effects produced by the solubilization of hydrophobic substances by micellar aggregates in water medium are quite important for applications of viscoelastic surfactant solutions for enhanced oil recovery (EOR), especially in hydraulic fracturing technology. The present paper aims at the investigation of the structural transformations produced by the absorption of an aliphatic hydrocarbon (n-decane) by mixed wormlike micelles of cationic (n-octyltrimethylammonium bromide, C8TAB) and anionic (potassium oleate) surfactants enriched by C8TAB. As a result of contact with a small amount (0.5 wt%) of oil, a highly viscoelastic fluid is transformed to a water-like liquid. By small-angle neutron scattering (SANS) combined with cryo-TEM, it was shown that this is due to the transition of long wormlike micelles with elliptical cross-sections to ellipsoidal microemulsion droplets. The non-spherical shape was attributed to partial segregation of longer- and shorter-tail surfactant molecules inside the surfactant monolayer, providing an optimum curvature for both of them. As a result, the long-chain surfactant could preferably be located in the flatter part of the aggregates and the short-chain surfactant-at the ellipsoid edges with higher curvature. It is proven that the transition proceeds via a co-existence of microemulsion droplets and wormlike micelles, and upon the increase of hydrocarbon content, the size and volume fraction of ellipsoidal microemulsion droplets increase. The internal structure of the droplets was revealed by contrast variation SANS, and it was shown that, despite the excess of the cationic surfactant, the radius of surfactant shell is controlled by the anionic surfactant with longer tail. These findings open a way for optimizing the performance of viscoelastic surfactant fluids by regulating both the mechanical properties of the fluids and their clean-up from the fracture induced by contact with hydrocarbons.

Inhibition of bromate formation in the O-3/PMS process by adding low dosage of carbon materials: Efficiency and mechanism

Ozone/peroxymonosulfate (O-3/PMS), firstly proposed by our group, is an efficient advanced oxidation process for the degradation of organic pollutants. However, the elevation of bromate formation was the main problem in the treatment of bromide-containing water. In this work, adding low dosage of powdered activated carbon (PAC), carbon nanotube (CNT) and graphene oxide (GO) in the inhibition of bromate formation and the enhanced degradation of organic pollutants during the O-3/PMS process were firstly investigated. As 10 mg/L of PAC, CNT and GO were added, the bromate conversion efficiency (25.1%) was decreased to 15.9%, 14.1%, and 8.8% at pH = 7.0, 50 mu M PMS addition and 1.135 mg min-1 ozone injection after 25 min reaction. It is shown that the carbon materials played a crucial role in reducing intermediate products (HOBr/OBr-) in the reaction, thereby blocked the bromate formation. This may be due to the defects such as vacancies and zigzag/armchair-like edges on the graphene boundary, which were reported as active sites for oxygen reduction reaction. Meanwhile, the addition of three carbon materials would also promote the degradation of oxalic acid and para-chlorobenzoic acid, and the effect of GO was better than the other two. According to the release of TOC in the reaction, the stability of GO was obviously stronger than that of PAC and CNT, which was attributed to that GO had a relatively stable lamellar structure. Finally, compared with the deionized water, the water matrices that would trap free radicals in actual water samples can significantly inhibit the bromate formation. Therefore, adding low dosage of carbon materials is an effective way to control the bromate formation and promote the degradation of organic pollutants in the O-3/PMS process.

The Interaction of Glymes with Surfactant Micelles

The critical micelle concentrations (CMC) values and counterion dissociation (alpha values) have been determined for a number of mixed micellar systems consisting of two typical ionic surfactants and glycol ethers (glymes) as cosurfactants, namely diethylene glycol dimethyl ether, diethylene glycol diethyl ether, triethylene glycol dimethyl ether, and tetraethylene glycol dimethyl ether. Conductance experiments were used to determine the CMC and alpha values of the mixed micelles as a function of glyme concentration in the aqueous mixed solvent. Favorable interactions between sodium dodecyl sulfate micelles and glyme cosurfactants were deduced from the decreases in the CMC values and the large increase in the alpha values of these systems as a function of increasing glyme concentration in the mixed solvents. In contrast to the anionic surfactant/glyme systems, in general, there appeared to be little favorable interactions between the surfactant and glymes when micelles of the cationic surfactant dodecyltrimethylammonium bromide were formed in water/glyme solvent systems containing an increasing amount of the glymes. The interaction of glymes with the surfactant micelles was examined closely via C-13 nuclear magnetic resonance (NMR) chemical shifts for both surfactant and glyme carbons; these chemical shifts changes were interpreted in terms of the distribution and the localization of the glymes in the aggregates. Finally, partition constants, determined from two-dimensional diffusion-oriented spectroscopy (2D-DOSY) experiments, were used to calculate thermodynamic quantities of transfer of the glymes between the bulk phase and the self-assembled aggregates. All these results are interpreted in terms of the key contributions that both the glyme ethoxylated groups and alkyl endgroups make to the hydrophobic interactions.

Evaluating the role of ionic liquids (ILs) in the crystallization of lysozyme

This investigation focuses on revealing the role of ionic liquids (ILs) on protein crystallization. Three different ILs, 1-Ethyl-3-methylimidazolium bromide ([Emim]Br), 1-Ethyl-3-methylimidazolium tetrafluoroborate ( [Emim] BF4), and 1-Butyl-3-methylimidazolium bromide ([Bmim]Br), and the model protein lysozyme were chosen for investigation. Studies were carried out both thermodynamically and kinetically. With the presence of ILs, a slight increase in the solubility and an obvious decrease in induction time were discovered. Results showed that ILs can affect lysozyme nucleation by arranging molecules in nuclei to linear like. The intermolecular interactions between ILs and lysozyme molecules were further revealed using Circular Dichroism Spectroscopy. The addition of ILs interacted with lysozyme molecules through changes in secondary structure. An increase in proportional to-helix content of lysozyme was achieved with the addition of a small amount of ILs, leading to more stable lysozyme molecules favorable for crystallization.

Cooperative Effects in Surfactant Adsorption Layers at Water/Alkane Interfaces

In the present work, the properties of dodecyl dimethyl phosphine oxide (C12DMPO) at the water/decane interface are studied and compared with those obtained earlier at the interface to hexane. To simulate the interfacial behavior, a two-component thermodynamic model is proposed, which combines the equation of state and Frumkin isotherm for decane with the reorientation model involving the intrinsic compressibility for the surfactant. In this approach, the surface activity of decane is governed by its interaction with C12DMPO. The theory predicts the influence of decane on the decrease of the surface tension at a very low surfactant concentration for realistic values of the ratio of the adsorbed amounts of decane and surfactant. The surfactant’s distribution coefficient between the aqueous and decane phases is determined. Two types of adsorption systems were used: a decane drop immersed into the C12DMPO aqueous solution, and a water drop immersed into the C12DMPO solution in decane. To determine the distribution coefficient, a method based on the analysis of the transfer of C12DMPO between water and decane is also employed.
