Aqueous phase behavior of the PEO-containing non-ionic surfactant C12E6: A molecular dynamics simulation study

Hypothesis: Non-ionic surfactants containing polyethylene oxide (PEO) chains are widely used in drug formulations, cosmetics, paints, textiles and detergents. High quality molecular dynamics models for PEO surfactants can give us detailed, atomic-scale information about the behavior of surfactant/water mixtures. Simulations: We used two molecular dynamics force fields (FFs), 2016H66 and 53A6(DBW), to model the simple non-ionic PEO surfactant, hexaoxyethylene dodecyl ether (C12E6). We investigated surfactant/water mixtures that span the phase diagram of starting from randomly distributed arrangements. In some cases, we also started with prebuilt, approximate models. The simulations results were compared with the experimentally observed phase behavior. Findings: Overall, this study shows that the spontaneous self-assembly of PEO non-ionic surfactants into different colloidal structures can be accurately modeled with MD simulations using the 2016H66 FF although transitions to well-formed hexagonal phase are slow. Of the two FFs investigated, the 2016H66 FF better reproduces the experimental phase behavior across all regions of the C12E6/water phase diagram. (C) 2020 Elsevier Inc. All rights reserved.

Two Cu(ii)-based coordination polymers: Dye degradation and important values on the later recovery of fracture patients by activating the WNT signaling pathway

Through utilizing the mixed-ligand method, two novel coordination polymers {[Cu(bpdc)(bpbenz)]}(n), (1, H(2)bpdc = [1,1′-biphenyl]-4,4′-dicarboxylic acid, bpbenz = 1,4-bis(4-pyridyl)benzene) and {[CR(bpdc)(bide)(2)]}(n) (2, bide = 4,4′-bis(imidazolyl)diphenyl ether) with structural diversity have been synthesized via Cu(NO3)(2)center dot 3H(2)O reacting with the rigidity bicarboxylic ligands H(2)bpdc in the existence of the distinct nitrogen-donor co-ligands. The photocatalytic degradation performance of complex 1 to distinct dye contaminants (MO, RhB and MB) was assessed. The results confirm that the photocatalytic degradation efficiency of complex 1 to the MB is the highest (MO 86.2%, RhB 85.7% and MB 92.1%). Their application values on the later recovery of fracture patients were then evaluated. The real time RT-PCR method was conducted to assess the osterix and n=2 relative expression levels in the mesenchymal stem cells (MSCs). The western blot method was implemented and the WNT (WNT is a fusion of two terms, wg derived from the Drosophila gene wingless (wg) and int derived from the proto-oncogene integration, which is the mammalian homolog of wg) protein expression levels were assessed.

Rapid, high-efficient and selective removal of cationic dyes from wastewater using hollow polydopamine microcapsules: Isotherm, kinetics, thermodynamics and mechanism

Developing new adsorbents with high adsorption capacity, rapid adsorption rate as well as good adsorption selectivity are highly demanded for efficiently purifying organic wastewater. We here reported new hollow polydopamine microcapsules (H-PDA-MCs) synthesized by a facile oxidation self-polymerization of dopamine using iron trioxide (Fe2O3) nano-cube as a template and considered as a high-efficiency adsorbent for capturing organic dyes. First, the morphology and microstructure of H-PDA-MCs were investigated through SEM, TEM, FTIR, XRD, N-2 adsorption and Zeta potential. The adsorption performance of H-PDA-MCs was systematically studied. Second, three kinetic models and five isothermal adsorption models were employed to study the adsorption process and the equilibrium adsorption behavior, respectively. Furthermore, the adsorption mechanism was discussed by FTIR, UV and XPS spectra. The results showed that H-PDA-MCs owned good selective adsorption behavior towards cationic dye. At 298.15 K, the maximum adsorption capacity of H-PDA-MCs towards MB was up to 191.55 mg g(-1) and the adsorption equilibrium time was only 60 min. The adsorption kinetic process was in line with the pseudo-second-order kinetic model, and the adsorption equilibrium data was well described by the Langmuir and Temkin isotherm models. The thermodynamic parameters demonstrated that the adsorption is an endothermic and spontaneous process.

Flavonoids composition and antioxidant potential assessment of extracts from Gannanzao Navel Orange (Citrus sinensis Osbeck Cv. Gannanzao) peel

The antioxidant effect of 95% ethanol extract and its three subfractions, PE (petroleum ether), EtOAc (ethyl acetate), and water extracts, from Gannanzao navel orange peel, were evaluated by ABTS (2,2 ‘-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)), DPPH (1,1-diphenyl-2-picryl-hydrazyl) and FRAP (ferric reducing/antioxidant potential) methods for the first time. Furthermore, the TPC (total polyphenol content), TFC (total flavonoid content), and primary individual flavonoids of the four extracts were analyzed and compared. The results indicated that: (1) the EtOAc extract exhibited the best antioxidant potential among these four extracts in all three antioxidant bioassay platforms; (2) Corresponding to the antioxidant potential, the EtOAc extract contained the highest contents of both TPC and TFC; (3) Compared with other extracts, the EtOAc extract was significantly (p < 0.01) rich in the contents of narirutin, sinensetin, nobiletin, 4 ',5,6,7-tetramethoxyflavone, and 3,3 ',4 ',5,6,7-hexamethoxyflavone, which might be the main bioactive compounds responsible for the excellent antioxidant potential of EtOAc extract.

Optimization of sulfobutyl-ether-beta-cyclodextrin levels in oral formulations to enhance progesterone bioavailability

Progesterone oral dose regimens are indicated for the treatment of luteal phase deficiency and estrogen dominance. The poor aqueous solubility of progesterone leads to erratic oral absorption, resulting in suboptimal or excessive plasma levels. Developing a formulation to enhance the solubility of progesterone in the gastrointestinal tract would be beneficial to decrease drug absorption variability and increase bioavailability. The solubility of progesterone at 400 mM sulfobutyl-ether-beta-cyclodextrin (SBE-beta-CD) concentration was similar to 7000-fold greater than its intrinsic solubility, aided by the formation of SBE-beta-CD-progesterone complex. The complex was characterized using differential scanning colorimeter, Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy techniques. FTIR and NMR studies of the complex confirm the interaction between functional groups of SBE-beta-CD and progesterone to form an inclusion complex. Molecular modeling studies demonstrated progesterone binding poses with four probable SBE-beta-CD isomers and these results matched with NMR and FTIR data. The progesterone oral formulations were optimized by increasing the levels of SBE-beta-CD in the formulation to prevent the displacement of progesterone from the complex by gastrointestinal contents. The oral bioavailability of progesterone in rats was increased 5-fold when administered with the optimized formulation compared to administration with progesterone API capsules. Studies demonstrated that the optimized formulation prevents precipitation of progesterone in the intestinal tract and increases progesterone oral bioavailability in rats.

Preparation of thin film nanocomposite hollow fiber membranes with polydopamine-encapsulated Engelhard titanosilicate-4 for gas separation applications

Among the various separation membranes, the thin-film nanocomposites (TFN) membranes have been widely applied for gas separation. In the present study, TFN hollow fiber membranes using polydopamine (PD)-encapsulated ETS-4 (Engelhard titanosilicate-4), PD-ETS-TFN, with a pore size of 3-4 angstrom were prepared for gas separation applications. The proposed TFN hollow fiber membranes were prepared by condensation-based interfacial polymerization (IP) between poly(ethylenimine) as an aqueous monomer and 1,3,5-benzenetricarbonyl trichloride as an organic monomer on a porous PES [poly(ether sulfone)] substrate. The dopamine-encapsulated ETS-4 was incorporated inside the polyamide layer to maximize the hydrophilicity of the membrane. Various methods were employed to analyze the structures and characteristics of the ETS-4 and TFN membranes, and tests were conducted to evaluate the permeance of H-2, CO2, N-2, and CH4 through PD-ETS-TFN. The results revealed a facilitated transport property toward CO2. Due to the molecular sieving effect of the ETS-4, the proposed membranes achieved a permeance as high as 60.4 GPU toward H-2 and H-2/CO2 selectivity of 14.3.
