Fluid flow profiles in free liquid films stabilised by anionic and cationic surfactants under an external electric field were investigated. Depthwise velocity fields were measured at the mid region of the free liquid film by confocal micron-resolution particle image velocimetry and corresponding numerical simulations were performed using Finite Element Method to model the system. Depthwise change in velocity profiles was observed with electroosmotic flow dominating in the vicinity of the gas?liquid and solid?liquid interfaces while backpressure drives fluid in the opposite direction at the core of the film. It was also found that the direction of the flow at various sections of the films depends on the type of surfactant used, but flow features remained the same. Numerical simulations predicted the flow profiles with reasonable accuracy; however, asymmetry of the actual film geometry caused deviations at the top half of the computational domain. Overall, electroosmotic flow profiles within a free liquid film are similar to that of the closed-end solid microchannel. However, the flow direction and features of the velocity profiles can be changed by selecting various types of surfactants. The free liquid films thickness was selected to match dimensions of foam Plateau border. Hence, these findings will be useful in developing a separation system based on foam electrokinetics.

Observation of the relations of the beta-lactum antibiotic drug levofloxacin hemihydrate (LFH) with of tetradecyltrimethylammonium bromide (TTAB) has been carried out by conductivity measurement technique in aqueous solution of alcohols and polyols at single fixed temperature (303.15 K) for different concentrations and at different temperatures (298.15?318.15 K) with interval of 5.0 K for one selected fixed concentration. For TTAB + LFH mixture with alcohols/polyols, a single critical micelle concentration (cmc) was found in this study. In presence of alcohols, the values of cmc for mixed systems LFH + TTAB exhibited higher (except for ethanol at 298.15 K) in magnitude in compare to their absence. This showed that the micellization of the mixture of LFH and TTAB was unfavorable to some extent in attendance of alcohols. In attendance of polyols, the cmc values for mixed systems LFH + TTAB was obtained smaller in scale in compare to their absence. This exhibited the early micellization of the mixture of LFH and TTAB. Values obtained for DeltaG0 m were negative, which indicate naturalness of the present study. The other kinds of thermodynamic parameters such as transfer enthalpy (DeltaH0 m.tr), transfer free energy (DeltaG0 m.tr), and transfer entropy (DeltaS0 m.tr) were also observed and demonstrated carefully. The compensation temperature (Tc) as well as the intrinsic enthalpy gain (DeltaH0? m) were also determined and interpreted. Moreover, the standard molar heat capacity (DeltaC0 m) for mixed system was evaluated and explained for the studied system.

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 1119-97-7 is helpful to your research. Safety of MitMAB

Shear-induced multilamellar vesicle (MLV) formation has been studied by coupling the small-angle neutron scattering (SANS) technique with neutron spin echo (NSE) spectroscopy. A 10% mass fraction of the nonionic surfactant pentaethylene glycol dodecyl ether (C12E5) in water was selected as a model system for studying weak inter-lamellar interactions. These interactions are controlled either by adding an anionic surfactant, sodium dodecyl sulfate, or an antagonistic salt, rubidium tetraphenylborate. Increasing the charge density in the bilayer induces an enhanced ordering of the lamellar structure. The charge density dependence of the membrane bending modulus was determined by NSE and showed an increasing trend with charge. This behavior is well explained by a classical theoretical model. By considering the Caille parameters calculated from the SANS data, the layer compressibility modulus B is estimated and the nature of the dominant inter-lamellar interaction is determined. Shear flow induces MLV formation around a shear rate of 10 s-1, when a small amount of charge is included in the membrane. The flow-induced layer undulations are in-phase between neighboring layers when the inter-lamellar interaction is sufficiently strong. Under these conditions, MLV formation can occur without significantly changing the inter-lamellar spacing. On the other hand, in the case of weak inter-lamellar interactions, the flow-induced undulations are not in-phase, and greater steric repulsion leads to an increase in the inter-lamellar spacing with shear rate. In this case, MLV formation occurs as the amplitude of the undulations gets larger and the steric interaction leads to in-phase undulations between neighboring membranes.

Synthesis of multilayered composite polymer particles comprising mainly poly(iso-butyl methacrylate)-block-polystyrene (PiBMA-b-PS) has been carried out by the use of two-step activator generated by electron transfer for atom transfer radical polymerization (AGET ATRP) in aqueous microsuspension. PiBMA-Br macroinitiator seed particles were prepared in the first step, followed by swelling with styrene and second step (seeded) polymerization. The blocking efficiency in the second step was found to be crucial with regards to the resulting particle morphology. A disordered sea-island morphology was obtained when the blocking efficiency was 47% (73% conversion), whereas a blocking efficiency of 61% (71% conversion) resulted in the formation of multilayered particles. High blocking efficiency can be achieved by careful adjustment of the activation rate by proper choice of polymerization temperature and amount of reducing agent (ascorbic acid).

Synthetic Route of 1119-97-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants.

The interaction of halide ions (I-, Br-, Cl-) with well-cleaned faceted platinum (nanocube, cuboctahedral) nanoparticles and platinum polycrystalline is investigated in 0.5 M H2SO4 electrolyte. Under electrochemical conditions, the Pt surface gets poisoned with halide ad-atoms and it causes the attenuation of both hydrogen adsorption/desorption in the lower potential region (0.06-0.4 V) and electroxidation of Pt nanoparticles in the higher potential region (0.6-1.2 V). Above certain concentration (5 ± 10-6 M), the strongly adsorbing I-ions mask the Hupd features. On the other hand, Br- and Cl- ions alter the peak features in the Hupd region, those are characteristic of different Pt surface sites. On excursion to higher potentials (?> 1.2 V), concurrent halogen evolution, Pt oxidation, and oxygen evolution are observed; the increase in peak intensity in the Hupd region reflects the reconstruction of the Pt surface. To remove the adsorbed halide ions from the Pt surface, an in-situ potentiostatic method is employed, which involves holding the working electrode at ?0.03 V in 0.1 M NaOH solution. The cleanliness and retention of surface-structure are confirmed from the voltammograms recorded in the test electrolyte and the recovery of oxygen reduction reaction (ORR) activity after cleaning the Br-ion-contaminated Pt surface supports this conjecture.

This study proposes a thermodynamic approach to effectively select functional agents onto zeolite for sodium dodecyl sulfate (SDS) sequestration in greywater reuse. We combine isothermal titration calorimetry (ITC) and quantum chemistry simulation (QCS) to identify the interactions between SDS and agents at the molecular level. Three potential agents, cetyl trimethyl ammonium bromide (CTAB), N,N,N-trimethyltetradecan-1-aminium bromide (C14TAB), and 14-hydroxy-N,N,N-trimethyltetradecan-1-aminium bromide (C14HTAB), differ in carbon chain length and hydrophilic groups. The ITC titration of SDS with CTAB released the highest heat, followed by those with C14TAB and C14HTAB, as was the same trend for the amounts of SDS adsorbed by the respective functionalized-zeolites. Results suggest that the favorable SDS sorption occurred at the bilayer CTAB-zeolite is driven by enthalpy as similar as the SDS?CTAB interaction found, regardless of the contribution from electrostatic and/or hydrophobic behaviors, while the declined sorption is entropy-driven via the predominant hydrophobic interaction onto the monolayer CTAB-zeolite. The data presented here interpret the nature of molecularly thermodynamic quantities and enable the manipulation of sorption capacity optimization.

The personal care products (PCPs) constitute various nonmedical products intended only for the application on the body surface and are not used to treat internal body problems like infections, etc. With a continuous change in culture and lifestyle in the society, the consumption of PCPs has increased several fold. In contrast, biocides are any chemical substances administered individually or in mixture with the intention of ?destroying, deterring, rendering harmless, preventing the action of, or otherwise exerting a controlling effect on, any harmful organism by any means other than mere physical or mechanical action.? The exponential rises in domestic application of PCPs and biocides have rendered them to be potential causes of environmental pollution. Their continuous detection in river bodies mainly due to improper treatment and uncontrolled release via sewage treatment plants has proven to be a leading cause of harm to ecological species. Some of them have been proved to have potential to become contaminants of emerging concern (CEC). Insufficient ecotoxicological data of PCPs for their environmental behavior and ecotoxicity have rendered Scientific Committee on Consumer Safety (SCCS) administered by the Directorate-General for Health and Consumer Protection of the European Commission to release guidelines pertaining to safer use and risk associated with it. On the other hand, Biocidal Products Regulation (BPR) EU 528/2012 was enacted to improve functioning of the biocide market and to ensure a high level of protection of human and animal health and the environment. In silico tools such as quantitative structure-activity relationship (QSAR) and read-across can be employed using existing information to rapidly identify the potentially most toxic and hazardous toxic PCPs/biocides and prioritize the most environmentally hazardous ones. QSAR is widely used to obtain predictions of known/untested or not yet synthesized chemicals in order to prioritize them as various toxic classes of potential hazard causing ingredients. The present chapter enlists the information related to impact and occurrence of PCPs/biocides along with their persistence, environmental fate, risk assessment, and risk management. Additionally, a special emphasis is given on in silico tools such as QSAR which can be employed in prediction of environmental fate of personal care products and biocides mainly related to the ecotoxicity to aquatic species. Finally, a detailed report is prepared on endpoints, ecotoxicity databases, and expert systems frequently used for ecotoxicity predictions of personal care products and biocides with the aim to justify the development and implementation of in silico tools in early risk assessment and reduction of animal experimentation.

The opportunistic pathogen, Acanthamoeba castellanii is the causative agent for the sight threatening infection Acanthamoeba keratitis (AK). It is commonly associated with contact lens wearers, and prevalence is increasing at an alarming rate due to an inadequate preventive strategy to protect the lens from this protist. This problem is compounded by the lack of an effective acanthamoebocide, particularly with cysticidal activity in the contact lens solutions. We have used cytotoxicity assays and a variety of biophysical approaches to show that two molecules with tails made of alkyl carbon, alkylphosphocholines (APCs) and quaternary ammonium compounds (QACs) had significant chain-length dependent efficacy against A. castellanii trophozoites, the latter producing death via permeabilization, and DNA complexing. QACs were more effective than APCs and had activity against cysts. Conversely, the QAC with 12 alkyl carbon chain, was non toxic, its presence increased A. castellanii trophozoites biomass and delayed encystation by 96 h. Interestingly, it was unable to induce excystation and increased trophozoite sensitivity to APC16. These results present a mono- and multi-inhibitor management strategy effective against trophozoites and cysts that may be useful for formulating into contact lense cleaning solutions and reducing AK incidence.

Mesoporous vanadia-silica catalysts have been prepared by three different sol-gel procedures using tetraethylorthosilicate (TEOS), vanadyl acetylacetonate (VAA), or VOCl3 and in some cases quaternary ammonium salts ((CH3)3C14H29N+Br – or (C10H21)4N+Br -) as surfactants. According to procedure A, TEOS and VAA were concomitantly hydrolyzed, in procedure B TEOS was prehydrolized and vanadium precursor was added to the silica sol, and in procedure C both TEOS and vanadium precursors were separately prehydrolized. The sol-gel procedures were controlled by checking the effect of the hydrolysis pH, refluxing time, surfactant, and conditions of gellifications (slow evaporation at room temperature or autoclavization). The samples were dried under vacuum, first at room temperature, then at 373 K, and finally calcined at 773 K. ICP-AES analysis indicated for all samples a vanadium content of around 6.5 wt%. The samples were impregnated with Cs2SO4 resulting in a Cs:V ratio of 3:1 and then dried and calcined under the same conditions. The catalysts were characterized using several methods: sorption isotherms of N2 at 77 K, XRD, and XPS. The results of the characterization indicated that during calcination of the V/Cs catalysts vanadia is dissolved in a sulfate containing molten salt. The activity of these catalysts for the oxidation of SO2 was tested in a gas containing 2% SO2, 19% O2, 79% N 2 in the temperature range 523-823 K. Similar experiments with gases containing 10% H2O in the feed or with wet catalysts were also performed. The activation of the catalysts and the catalytic behavior were monitored by in situ Raman and EPR spectroscopy. These characterization techniques indicated that the active molten phase contains vanadium oxosulfato complexes similar to the V2O5-M2S 2O7 (M=alkali metal)-based industrial catalyst, where kieselghur is used as carrier material. The high dispersion of vanadium in the studied catalysts results in an increased catalytic activity for the oxidation of SO2 contained in feed gases with low SO2 content.
