Mixed micellization behaviour of tri-substituted surface active ionic liquid and cationic surfactant in aqueous medium and salt solution: Experimental and theoretical study

The aim of the present study is to investigate the mixed micellization behaviour of trisubstituted surface active ionic liquid (SAIL) 1-tetradecyl-2,3-dimethylimidazolium bromide [C(14)bmim][Br] and cationic surfactant cetyltrimethylammonium bromide ((TAB) in aqueous solution and in the presence of inorganic salt, sodium bromide (NaBr) using the conductivity, steady-state fluorescence and H-1 NMR measurements. The degree of counter-ion dissociation (g), critical micelle concentration (cmc), various thermodynamic parameters of micellization (Delta G(m)(0), Delta H-m(0) and Delta S-m(0)) have been evaluated from conductivity measurements. All these parameters show that strong synergistic interactions have been observed in the studied mixed systems in the aqueous medium and the presence of salt promotes the electrostatic interactions that result in lowering of cmc values. The aggregation number (N-agg) of mixed micelle has been ascertained from steady-state fluorescence quenching indicate that the contribution of CTAB was always more than that of SAIL. The results have been analysed on the basis of Rubingh, Clint and Motomura theory. Various mixed micellar parameters such as ideal cmc (cmc*), activity coefficients (f(1) and f(2)), micellar mole fraction of CTAB in mixed and ideal state (X(1)(m)and X-1(ideal)), interaction parameter (beta(m)) and excess Gibbs free energy of micellization (Delta G(ex)) have been calculated at temperatures of (298.15, 308.15 and 318.15) K. Mixed micellar parameters (cmc*, X-1(m), and Delta G(ex)) reveal non-ideal behaviour of the mixed system and magnitude of interaction parameter (beta(m)) becomes more negative in the presence of salt. H-1 NMR shed light on the electrostatic interactions between CTAB and SAIL in mixed state. (C) 2019 Elsevier B.V. All rights reserved.

The formate electrooxidation on Pt/C and PtSnO2/C nanoparticles in alkaline media: The effect of morphology and SnO2 on the platinum catalytic activity

Pt/C and PtSnO2/C electrocatalysts with and without cubic preferential morphology were used for formate electrooxidation reaction (FER) in alkaline medium. The synthesis of catalysts was carried out by alcohol reduction method using KBr as a shape directing agent (Bromide Anion Exchange method BAE). The X-ray diffraction (XRD) showed characteristic peaks of the Pt face-centered cubic (FCC) structure, as well as cassiterite SnO2. The Transmission Electron Microscopy (TEM) and Scanning Transmission Electron Microscopy (STEM) micrographs show SnO2 dispersed onto carbon support and adjacent to the Pt nanoparticles (NPs), as well as cubic Pt NPs. The cyclic voltammetry (CV) measurements show that the current density peak for FER on Pt/C (100) is 2.40 times higher than on Pt/C polycrystalline (poly). The current density at end of chronoamperometry (CA) analysis on PtSnO2/C poly was 1.33 and 5.29 times higher than on Pt/C (100) and Pt/C poly, respectively. The presence of SnO2 and the (100) facets of platinum cubic morphology might prevent platinum surface deactivation caused by intermediates formed during the FER process.

A novel method for the synthesis of pyrido[1,2-b][2]benzazepines on the basis of 2-(bromomethyl)benzophenones and 2-(bromomethyl)benzaldehyde

A novel method for the synthesis of pyrido[1,2-b][2]benzazepine derivatives is based on the reaction of 2-(bromomethyl)benzophenones and 2-(bromomethyl)benzaldehyde with 2-methylpyridines. The route of synthesis of 6H-pyrido[1,2-b][2]benzazepinium salts includes several steps with the possibility of isolating intermediate 1-benzyl-2-methylpyridinium and 11-aryl-11-hydroxy-11,12-dihydro-6Hpyrido[1,2-b][2]benzazepinium bromides. The efficiency of dehydration of intermediate carbinols increases with the use of protic solvents, an increase in heating time, and in the presence of electron-withdrawing substituents in the benzazepine moiety. The structure of the reaction products was proved by mass spectrometry, IR and one- and two-dimensional correlation NMR spectroscopy.

Ruddlesden-Popper-Phase Hybrid Halide Perovskite/Small-Molecule Organic Blend Memory Transistors

Controlling the morphology of metal halide perovskite layers during processing is critical for the manufacturing of optoelectronics. Here, a strategy to control the microstructure of solution-processed layered Ruddlesden-Popper-phase perovskite films based on phenethylammonium lead bromide ((PEA)(2)PbBr4) is reported. The method relies on the addition of the organic semiconductor 2,7-dioctyl[1]benzothieno[3,2-b]benzothiophene (C-8-BTBT) into the perovskite formulation, where it facilitates the formation of large, near-single-crystalline-quality platelet-like (PEA)(2)PbBr4 domains overlaid by a approximate to 5-nm-thin C-8-BTBT layer. Transistors with (PEA)(2)PbBr4/C-8-BTBT channels exhibit an unexpectedly large hysteresis window between forward and return bias sweeps. Material and device analysis combined with theoretical calculations suggest that the C-8-BTBT-rich phase acts as the hole-transporting channel, while the quantum wells in (PEA)(2)PbBr4 act as the charge storage element where carriers from the channel are injected, stored, or extracted via tunneling. When tested as a non-volatile memory, the devices exhibit a record memory window (>180 V), a high erase/write channel current ratio (10(4)), good data retention, and high endurance (>10(4) cycles). The results here highlight a new memory device concept for application in large-area electronics, while the growth technique can potentially be exploited for the development of other optoelectronic devices including solar cells, photodetectors, and light-emitting diodes.

Honokiol-camptothecin loaded graphene oxide nanoparticle towards combinatorial anti-cancer drug delivery

Honokiol (HK) is a natural product isolated from the bark, cones, seeds and leaves of plants belonging to the genus Magnolia. It possesses anti-cancer activity which can efficiently impede the growth and bring about apoptosis of a diversity of cancer cells. The major concerns of using HK are its poor solubility and lack of targeted drug delivery. In this study, a combinatorial drug is prepared by combining HK and camptothecin (CPT). Both CPT and HK belong to the Magnolian genus and induce apoptosis by cell cycle arrest at the S-phase and G1 phase, respectively. The combinatorial drug thus synthesised was loaded onto a chitosan functionalised graphene oxide nanoparticles, predecorated with folic acid for site-specific drug delivery. The CPT drug-loaded nanocarrier was characterised by X-ray diffractometer, scanning electron microscope, transmission electron microscope, UV-vis spectroscopy and fluorescence spectroscopy, atomic force microscopy. The antioxidant properties, haemolytic activity and anti-inflammatory activities were analysed. The cellular toxicity was analysed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT assay) and Sulforhodamine B (SRB) assay against breast cancer (MCF-7) cell lines.

Physicochemical Characteristics of a Variant of Chaperon GroEL Apical Domain Designed to Enhance the Expression and Stability of Target Proteins

This work describes the properties of a new protein, a modification of GroEL apical domain designed to be a leader in fusion systems. This polypeptide leader demonstrates a high level of expression in a bacterial system; it is soluble and retains its solubility during standard biochemical manipulations. The secondary structure of the protein and its thermostability, as well as the protein solubility, were studied in a wide temperature range. To simplify the subsequent purification of the target protein, the possibility of its chemical cleavage from the fused protein by methionine residues with cyanogen bromide is provided.

Weissella cibaria EIR/P2-derived exopolysaccharide: A novel alternative to conventional biomaterials targeting periodontal regeneration

Healing and regeneration of periodontium are considered as a complex physiological process. Therefore, treatments need to be addressed with highly effective components modulating the multiple pathways. In this study, exopolysaccharide (EPS) produced by Weissella cibaria EIR/P2, was partially purified from the culture supernatant and subjected to characterization within the aim of evaluating its potential for periodontal regeneration. High-Performance Liquid Chromatography analysis revealed a single-peak corresponding to the glucose which identified the EPS as dextran. Fourier transform-infrared spectra were also displayed characteristic peaks for polysaccharides. According to the results of gel permeation/size exclusion-chromatography, the molecular mass was determined to be 8 x 10(6) Da. To clarify its anti-bacterial activity on Streptococcus mutans, effects on viability and biofilm formation was evaluated. At 50 mg/mL, dextran exhibited a bactericidal effect with 70% inhibition on biofilm formation. Besides, dose-dependent antioxidant effects were also detected. The efficacy of dextran in enhancing the viability of human periodontal ligament fibroblast cells (hPDLFCs) was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium-bromide (MTT) assay, and an increase was observed in the viability of hPDLFCs. In conclusion, dextran derived from W. cibaria can be potentially used as a multi-functional bioactive polymer in the design of new therapeutic strategies to promote healing and regeneration of periodontium.

A pore-scale study on improving CTAB foam stability in heavy crude oil-water system using TiO2 nanoparticles

The main challenge of foam injection for enhanced oil recovery (EOR) is foam stability at harsh reservoir conditions. With regard to this matter, this research aims to investigate the effect of TiO2 nanoparticles (NPs) in improving the stability of foam bubbles in porous media. The conductivity of hexadecyltrimethylammonium bromide (CTAB) solutions was measured to determine critical micelle concentration (CMC). Thereafter, TiO2 NPs were added into the foam solution and pH, contact angle, and interfacial tension (IFT) in the presence and absence of CTAB were measured. The stability of foam bubbles was evaluated through bulk foam tests and absorbance measurements. Finally, different nanofluids (at the concentrations of 0.00, 0.01, 0.03, 0.06, and 0.10 wt%), nano-CTAB solutions (at the concentrations of 0.00, 0.01, 0.03, 0.06, and 0.1 wt% NPs at the CMC of CTAB) and foams (at the concentrations of 0.00, 0.01, 0.03, 0.06, and 0.1 wt% NPs and at the CMC of CTAB) were injected into a heavy oil saturated heterogeneous porous medium. The results of the conductivity measurements showed that the highest adsorption of CTAB molecules onto the NPs surfaces occurs at 0.03 wt% NPs and 0.03 wt% CTAB. The results of micro- and macroscopic images from bulk foam tests revealed improved foam stability for this nano-CTAB foam. Moreover, contact angle and IFT results showed further improvement in interfacial properties for the mixture of NPs and CTAB solutions. Ultimately, in terms of oil recovery, the highest oil recovery factor (54%) was observed upon injection of foam with 0.03 wt% TiO2 NPs and 0.03 wt% CTAB, compared to the 22% recovery factor of DW injection. The visualization experiments showed that 32% enhancement in the recovery factor was mainly due to oil production from dead-end pores. This was because of different functions of NPs including stabilization of foam bubbles, wettability alteration, and improved foam generation mechanisms.

Rumex dentatus could be a potent alternative to treatment of microbial infections and of breast cancer

OBJECTIVE: To investigate the phytochemicals and in vitro antioxidant, antimicrobial and cytotoxic potential of Rumex dentatus (R. dentatus) leaf extracts. METHODS: The total phenolics and flavonoids content of R. dentatus extracts were evaluated by the Folin-Ciocalteu and aluminum chloride colorimetric methods respectively. Antioxidant potential of studied plant extracts was assessed through 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity, total reducing power and total antioxidant methods. Moreover, antibacterial and antifungal capacity was also evaluated by disc diffusion method against six clinically isolated multi-drug bacterial strains as well as six fungal isolates. Further, cell cytotoxicity was also evaluated through 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazoliurn bromide assay. RESULTS: Ethanol extract showed highest total phenolic [(38.9 +/- 1.5) pg gallic acid equivalent/mg] and total flavonoids [(17.2 +/- 1.9) mu g quercetin equivalent /mg] contents. Antioxidant assays indicated that ethanol and methanol extracts possess potent antioxidant potential. Moreover, it was observed that ethanol and hexane extracts have the potential to inhibit most of the tested multi-drug resistant bacterial strains while methanol, chloroform and hexane extracts could inhibit the growth of pathogenic fungal strains successfully. Among all the studied extracts, ethanolic extract showed highest cytotoxicity against MCF-7 cell line then Hep-2 and DU-145 cell lines by MTT assay with lowest IC50 of 47.3 mu g/mL. CONCLUSION: These results suggest that R. dentatus could be a potent alternative candidate for treatment of microbial infections and for breast cancer treatment. (C) 2019 JTCM. All rights reserved.
