Ionic and pH responsive thin film composite hollow fiber nanofiltration membrane for molecular separation

Ionic and pH responsive thin film composite (TFC) membrane is prepared by interfacial polymerization of lysine and trimesoyl chloride on the out surface of poly (m-phenylene isophthalamide) hollow fiber membrane. Hydrophilicity and strong negative charge of the TFC membrane are obtained by introducing a large amount of carboxylic groups in the cross-linked polyamide network, endorsing the ionic and pH response of the TFC membrane in terms of flux and rejection. The TFC membrane shows almost 100% rejection for Eriochrome black T, with a flux of 35.8 L/m(2)h (0.2 MPa) at low pH and salt concentration. However, the rejection decreases to 95.8%, and the flux increases more than three times at high pH and salt concentration due to the shift of the interaction in the polyamide network from hydrogen bonding to static-electric repulsion. The responsive TFC membrane also shows great performance in separation of dye-salt mixture and dye mixture.

Adsorption of Indigo Carmine dye onto the surface-modified adsorbent prepared from municipal waste and simulation using deep neural network

A new adsorbent was prepared from municipal wastes (a mixture of Corn Stover, Paper Waste, and Yard Waste) by cationization with 3Chloro2 Hydroxypropyl Trimethylammonium Chloride. The FTIR spectrum confirmed the quaternary ammonium group’s presence on the adsorbent surface (1450 cm-1). The maximum adsorption capacity (148 mg/g) was higher than the earlier reported values. Liu isotherm described well the adsorption process, with a high R2adj value (0.997). The pseudo-first-order equation fits well for kinetic data, and thermodynamic experiments demonstrated the endothermic nature of the adsorption. The deep neural network (DNN) is applied to simulate the adsorption process, which outperformed the classical machine learning and shallow neural network models. The DNN model predicted accurately the adsorption process with the lowest deviation from the actual values with Mean Absolute Error (MAE = 3.2), Root Mean Squared Error (RMSE = 4.89), and the highest performance accuracy of R-2 (0.96) as compared to various classical ML algorithms such as Linear Regressions (MAE = 12.53, RMSE = 18.01, R-2 = 0.42), Random Forest (MAE = 5.81, RMSE = 10.05, R-2 = 0.82), and Extra Trees (MAE = 4.35, RMSE = 8.22, R-2 = 0.88). The utilized DNN model can be used for predicting the removal efficiency of dyes for various combinations of input parameters without going through laboratory experiments.

Composition, antioxidant activity, and neuroprotective effects of anthocyanin-rich extract from purple highland barley bran and its promotion on autophagy

Anthocyanin-rich purple highland barley has attracted great attention recently due to its health benefits in humans. The composition of the purified anthocyanin extract (PAE) from purple highland barley bran (PHBB) was characterized by liquid chromatography-mass spectrometry (LC-MS) with a high acylated anthocyanin profile. PAE exhibited high antioxidant activity and potential neuroprotective effects on cobalt chloride (CoCl2)-induced hypoxic damage in PC12 cells by maintaining cell viability, restoring cell morphology, inhibiting lactic dehydrogenase (LDH) leakage, reducing reactive oxygen species (ROS) levels, enhancing antioxidant enzyme activities, inhibiting cell apoptosis, and attenuating cell cycle arrest. Treatment cells (PC12 and U2OS) with PAE activated autophagy, indicating that autophagy possibly acted as a survival mechanism against CoCl2-induced injury. This study demonstrated that PAE from the PHBB was a high-quality natural functional food colorant and potentially could be used as a preventive agent for brain dysfunction caused by hypoxic damage.

Estimation of Thermodynamic Properties and Phase Equilibria in Systems of Deep Eutectic Solvents by PC-SAFT EoS

This study examines the capabilities and shortcomings of perturbed-chain-statistical associating fluid theory equations of state (PC-SAFT EoS) applied for predicting properties and phase equilibria in systems of deep eutectic solvents. Treating deep eutectic solvents as pseudo-pure compounds and describing them as mixtures of two independent constituents are explored. Examples of choline chloride as the hydrogen bond acceptor (HBA) and levulinic acid, ethylene glycol, and phenol as hydrogen bond donors (HBDs) in a 1:2 molar ratio are considered. Excess properties of deep eutectic solvents with n-alkanols and water along with solubilities of carbon dioxide and ammonia are also considered. Besides that, liquid-liquid ternary systems of deep eutectic solvents with n-alkanes and 1-alkanols are analyzed. It has been found that although the pseudo-pure compounds approach with 2B associative scheme correctly estimates excess volumes, it exhibits poor accuracy in predicting excess enthalpies, solubility data, and liquid-liquid equilibria in ternary systems. When a temperature-dependent binary interaction between HBA and HBDs is applied, the individual approach predicts these properties in a more accurate manner.

Hydrogels based on physically cross-linked network with high mechanical property and recasting ability

In this work, hydrogels based on polyvinyl alcohol (PVA), acrylamide (AM), calcium chloride, and t-carrageenan were prepared via radical polymerization followed by freezing and thawing process. Comparing with pure PVA hydrogels, the obtained hydrogels possess higher tensile strength (1.54 MPa), Young’s modulus (92 kPa), and breaking energy (5.14 MJ/m(3)) due to the synergistic effect of physical cross-linkers containing PVA crystallization, double helix structures of carrageenan and hydrogen bond. Furthermore, the tensile stress of the hydrogel is negligibly changeable after twenty successive loading-unloading tensile tests under different strain demonstrating good fatigue resistance. And the hydrogels can also be recast many times under high temperature, which is favorable for the reuse of materials. Besides, the directional motion of ions endows the hydrogels with electronic conductivity which is very sensitive to the strain deformation. Together with the good mechanical property the hydrogels may have the promising application in flexible sensors.

A Visible-Light-Regulated Chloride Transport Channel Inspired by Rhodopsin

Inspired by the light-regulating capabilities of naturally occurring rhodopsin, we have constructed a visible-light-regulated Cl–transport membrane channel based on a supramolecular host-guest interaction. A natural retinal chromophore, capable of a visible-light response, is used as the guest and grafted into the artificial channel. Upon introduction of an ethyl-urea-derived pillar[6]arene (Urea-P6) host, threading or de-threading of the retinal and selective bonding of Cl- can be utilized to regulate ion transport. Based on the visible-light responsiveness of the host-guest interaction, Cl- transport can be regulated by visible light between ON and OFF states. Visible-light-regulated Cl- transport as a chemical model permits to understand comparable biological ion-selective transport behaviors. Furthermore, this result also supplies a smart visible-light-responsive Cl- transporter, which may have applications in natural photoelectric conversion and photo-controlled delivery systems.

Ethyl acetate fraction from Nymphaea hybrida Peck modulates inflammatory responses in LPS-stimulated RAW 264.7 cells and acute inflammation murine models

Ethnopharmacological relevance: Nymphaea hybrida Peck is used as a traditional medicinal herb for treating pain and inflammatory diseases, and known for its ornamental value and as a hot drink. However, the effects of N. hybrida polar fractions on lipopolysaccharide (LPS)-induced in vitro inflammation model and acute inflammation murine models have yet to be evaluated. Aim of the study: The aim of this study was to elucidate the anti-inflammatory effects of N. hybrida ethanol extract (NHE) and its polar fractions: petroleum ether (PE), methylene chloride (MC), ethyl acetate (EA), methanol (ME), and water (WA). The underlying molecular mechanisms of active fraction in LPS-stimulated RAW 264.7 murine macrophages were further investigated. Material and methods: Fractions with potential anti-inflammatory effects were screened using direct nitric oxide (NO) radical scavenging and cyclooxygenase (COX)-2 inhibition assays in vitro. The anti-inflammatory properties of potential fraction were evaluated in LPS-stimulated RAW264.7 cells, xylene-induced ear edema, carrageenaninduced paw edema and xylene-induced Evans blue exudation of acute inflammation murine models. The regulation of nuclear factor-kappa B (NF-kappa B) and mitogen-activated protein kinase (MAPK) signaling pathways were investigated using western blotting and immunofluorescence. Results: Compared to other polar fractions, NHE-EA displayed higher phenol and flavonoid content, and exerted greater activity in direct NO radical scavenging and COX-2 inhibition assay in vitro. NHE-EA markedly decreased the levels of inflammatory mediators, NO and prostaglandin E-2 (PGE(2)), by suppressing the over-expression of inducible nitric oxide synthase (iNOS) and COX-2 in LPS-stimulated RAW264.7 cells. The NHE-EA fraction dose dependently alleviated over-elevation of LPS-associated intracellular calcium and decreased the abnormal secretion of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-6, and interferon-gamma (IFN-gamma). The combination with NHE-EA effectively attenuated the activation and nuclear trans location of NF-kappa B p65, and the phosphorylation of extracellular signal-regulated kinases (ERK), c-Jun N-terminal kinases (JNK), and p38 kinases of MAPK pathways. NHE-EA could significantly ameliorate the degree of swelling of the mice ear and paw, the skin exudation of Evans blue and the excessive secretion of inflammatory cytokines. Conclusion: Our results demonstrated that NHE-EA was the most active polar fraction of N. hybrida extracts. It inhibited the LPS-associated inflammatory response by blocking the activation of NF-kappa B and MAPKs pathways in RAW264.7 cells. It also effectively alleviated the inflammatory response of acute inflammation. These results

Effect of high temperature and accelerated aging in high density micro-concrete

The design of concrete often requires numerous mix proportions and tentative mixings, which translates into a great number of specimens and tests. The process may be optimized by using small-scale specimens, which results in the saving of material, equipment and time, offering advantages such as better handling, easy kneading or smaller curing spaces. Nevertheless, the ability of small-scale specimens to reproduce the experimental properties determined through conventional samples is an open issue. The hypothesis of this study is that the differences between standard and small-scale specimens may be mitigated by applying a change of scale to the aggregates. The durability of high-density concrete for radiation shielding, in terms of weathering resistance and behaviour against heating cycles, has been determined by means of conventional and small-scale specimens (including scaled aggregates). The effects of various aggressive external agents (heating cycles, seawater and water with K2SO4) and the correlation between the results from scaled and standard specimens were determined. The analysis of the results enabled to establish the suitability of the use of micro-concretes to characterize concretes. In this study, the correlations between scaled and non-scaled models have been obtained in properties such as compressive strength, mass variation and ultrasonic pulse velocity after undergoing durability and thermal exposition tests.

Aqueous-phase behavior of glyoxal and methylglyoxal observed with carbon and oxygen K-edge X-ray absorption spectroscopy

Glyoxal (CHOCHO) and methylglyoxal (CH3C(O)CHO) are well-known components of atmospheric particles and their properties can impact atmospheric chemistry and cloud formation. To get information on their hydration states in aqueous solutions and how they are affected by the addition of inorganic salts (sodium chloride (NaCl) and sodium sulfate (Na2SO4)), we applied carbon and oxygen K-edge X-ray absorption spectroscopy (XAS) in transmission mode. The recorded C K-edge spectra show that glyoxal is completely hydrated in the dilute aqueous solutions, in line with previous studies. For methylglyoxal, supported by quantum chemical calculations we identified not only C-H, C=O and C-OH bonds, but also fingerprints of C-OH(CH2) and C=C bonds. The relatively low intensity of C=O transitions implies that the monohydrated form of methylglyoxal is not favored in the solutions. Instead, the spectral intensity is stronger in regions where products of aldol condensation and enol tautomers of the monohydrates contribute. The addition of salts was found to introduce only very minor changes to absorption energies and relative intensities of the observed absorption features, indicating that XAS in the near-edge region is not very sensitive to these intermolecular organic-inorganic interactions at the studied concentrations. The identified structures of glyoxal and methylglyoxal in an aqueous environment support the uptake of these compounds to the aerosol phase in the presence of water and their contribution to secondary organic aerosol formation.

Examination of inorganic gaseous species and condensed phases during coconut husk combustion based on thermodynamic equilibrium predictions

Multi-component thermodynamic equilibrium predictions of coconut husk combustion products were performed in this work. The calculation results showed that the concentration of the chlorine species in the flue gas and ash were clearly influenced by the combustion temperature. At temperatures below 820 degrees C the highest concentration was HCl(g), and above 820 degrees C was KCl(g). Chlorine species were also observed in ash, as KCl-NaCl-RbCl solid solution (when the combustion temperature was lower than 700 degrees C), and KCl-NaCl-K2SO4-Na2SO4 liquid solution (in the range of 600-960 degrees C). At low combustion temperatures (600 degrees C), chlorine retention in solid ash was the most effective. Speciation of inorganic gaseous species and condensed phases were investigated also during flue gas cooling from 1000 to 200 degrees C. Major condensed phase compositions were dominated by alkali metal salts in both solid and liquid phase states. In addition, the Gibbs energy of substance formation, and Gibbs reaction energy, in order to thoroughly interpret the thermodynamic predictions were determined. Finally, thirty seven eutectic points for binary systems calculated in the Phase Diagram module of the FactSage package were presented. For the purposes of interpreting the results, the melting point ranking for pure substances and binary systems were created. (c) 2020 Elsevier Ltd. All rights reserved.
