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.

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.

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.

Comparative study on the liquid desiccant dehumidi fi cation performance of lithium chloride and potassium formate

Liquid desiccant dehumidification is promising as it could be driven by renewable energy. In the present study, it newly investigated the dehumidification characteristics of KCOOH solution in an internally cooled dehumidifier. To select suitable concentration range, the vapor pressure of KCOOH solution with different solution concentration and temperature was measured with static method firstly. Then comparative experimental study was conducted to identify the dehumidification performance of KCOOH and LiCl solution under different solution and air flow rate, temperature and air humidity. Experimental results indicated that 70.3% KCOOH solution had almost the same vapor pressure as 35% LiCl solution. Under the same experimental conditions, the absolute moisture removal of 70.3% KCOOH solution was slightly higher than that of 35% LiCl solution as a result of the increased wetting area. It was found that the mass transfer coefficients of the two liquid desiccants were almost the same. An empirical correlation of Sh number was obtained to predict the mass transfer coefficient of KCOOH solution for dehumidification with a mean absolute relative deviation of 7.81%.

A combined interfacial polymerization and in-situ sol-gel strategy to construct composite nanofiltration membrane with improved pore size distribution and anti-protein-fouling property

Pore size distribution is crucial for the application of nanofiltration membrane in size-selective separation of industrial fluids. In this work, a novel combined interfacial polymerization (IP) and in-situ sol-gel strategy was proposed to fabricate composite nanofiltration membrane with narrow pore size distribution. Aqueous solution of piperazine and polyvinyl alcohol (PVA) was employed to perform interfacial polymerization with organic solution of trimesoyl chloride and tetraethyl orthosilicate (TEOS) on porous support. The non-reactive additive TEOS within the interfacially synthesized selective separation layer was then employed to perform sol-gel. The space-limited hydrolysis and condensation of TEOS molecules and their chemical bonding with PVA molecules were confirmed by analyzing membrane physico-chemical property and were found to be effective in tuning mean pore diameter, narrowing the pore size distribution and thus enhancing membrane perm-selectivity. Compared to those of membrane PA1 with similar mean pore size fabricated by only IP technique, the water permeability and rejection ratio of PEG1000 to raffinose (R-PEG1000/R-raffinose) of membrane PA-TEOS0.5 fabricated by combined IP and sol-gel technique were higher by 25.0 and 20.1%, respectively. Moreover, static adsorption and dynamic deposition tests using aqueous bovine serum albumin solution proved that in-situ sol-gel process could endow the membrane with better protein fouling resistance.

Experimental investigation of the influence of salt on the phase transition temperature in saline soil

Phase transition temperatures are important indexes to distinguish salt expansion and frost heave in frozen saline soil. By a series of cooling experiments, the phase transition temperatures of sodium chloride and sodium sulfate saline soils were measured for different salt concentrations. The results showed that the freezing temperature of saline soil is lower than that of a bulk solution of equivalent concentration. Affected by the surface energy of the ice/liquid solution, the freezing temperature deviations between the soil pore solution and bulk solution gradually increase with increasing salt concentration, whereas the degree of supersaturation of saline soil decreases. The eutectic temperature of saline soil is not constant but varies with the salt concentration. The accumulation of both ice and salt crystals affects the eutectic temperature. Though the freezing temperatures and salt crystallization temperatures between loess and silty clay are similar, prominent deviations appear in the eutectic temperatures. In addition, the phase diagram of the pore solution in saline soil is discussed. This work promotes an understanding of the phase transition process and the deformation of saline soil during cooling.

Genetic deletion of connexin 37 causes polyuria and polydipsia

The connexin 37 (Cx37) channel is clustered at gap junctions between cells in the renal vasculature or the renal tubule where it is abundant in basolateral cell interdigitations and infoldings of epithelial cells in the proximal tubule, thick ascending limb, distal convoluted tubule and collecting duct; however, physiological data regarding its role are limited. In this study, we investigated the role of Cx37 in fluid homeostasis using mice with a global deletion of Cx37 (Cx37(-/-) mice). Under baseline conditions, Cx37(-/-) had similar to 40% higher fluid intake associated with similar to 40% lower urine osmolality compared to wild-type (WT) mice. No differences were observed between genotypes in urinary adenosine triphosphate or prostaglandin E2, paracrine factors that alter renal water handling. After 18-hours of water deprivation, plasma aldosterone and urine osmolality increased significantly in Cx37(-/-) and WT mice; however, the latter remained similar to 375 mmol/kg lower in Cx37(-/-) mice, an effect associated with a more pronounced body weight loss despite higher urinary AVP/creatinine ratios compared to WT mice. Consistent with this, fluid intake in the first 3 hours after water deprivation was 37% greater in Cx37(-/-) vs WT mice. Cx37(-/-) mice showed significantly lower renal AQP2 abundance and AQP2 phosphorylation at serine 256 than WT mice in response to vehicle or dDAVP, suggesting a partial contribution of the kidney to the lower urine osmolality. The abundance and responses of the vasopressin V-2 receptor, AQP3, NHE3, NKCC2, NCC, H+-ATPase, alpha ENaC, gamma ENaC or Na+/K+-ATPase were not significantly different between genotypes. In summary, these results demonstrate that Cx37 is important for body water handling.

Toward tailoring of a new draw solute for forward osmosis process: Branched poly (deep eutectic solvent)-decorated magnetic nanoparticles

The introduction of suitable draw solutes is a critical factor in increasing water permeability of a forward osmosis (FO) process. In this study, a branched poly (deep eutectic solvent) was synthesized by surface initiated ring opening polymerization of glycidol on the magnetic core followed by introducing choline chloride as hydrogen bond acceptor to glycerol moieties. Due to the polyionic nature of as-synthesized material, it was expected to represent high osmotic pressure and high water flux. Moreover, the existence of Fe3O4 magnetic nanoparticles as core leads to easy separation of draw solute by an external magnetic field with low energy consumption. The FO performance of the branched poly (deep eutectic solvent)@Fe3O4 as a draw solute was investigated where the water flux of 17.9 L m(-2) h(-1) (LMH) and the reverse solute flux of 0.12 g m(-2) h(-1) (gMH) were obtained for 3.5 g L-1 solution. The recyclability of magnetic draw solute was also studied to ensure the FO applicability. Moreover, the brackish water containing 0.2 M and 0.3 M NaCl was also employed as a feed solution to evaluate the capability of branched poly (deep eutectic solvent)@Fe3O4 for the water desalination process.

Freshwater salinization increases survival of Escherichia coli and risk of bacterial impairment

Elevated levels of Escherichia coli (E. coli) are responsible for more designated freshwater stream impairments than any other contaminant in the United States. E. coli are intentionally used as a sentinel of fecal contamination for freshwaters because previous research indicates that salt concentrations in brackish or marine waters reduce E. coli survival, rendering it a less effective indicator of public health risks. Given increasing evidence of freshwater salinization associated with upland anthropogenic land-use, understanding the effects on fecal indicators is critical; however, changes in E. coli survival along the freshwater salinity range (<= 1500 mu S cm(-1)) have not been previously examined. Through a series of controlled mesocosm experiments, we provide direct evidence that salinization causes E. coli survival rates in freshwater to increase at conductivities as low as 350 mu S cm(-1) and peak at 1500 mu S cm(-1), revealing a subsidy stress response across the freshwater-marine continuum. Furthermore, specific base cations affect E. coli survival differently, with Mg2+ increasing E. coli survival rates relative to other chloride salts. Further investigation of the mechanisms by which freshwater salinization increases susceptibility to or exacerbates bacterial water quality impairments is recommended. Addressing salinization with nuanced approaches that consider salt sources and chemistry could assist in prioritizing and addressing bacterial water quality management. (C) 2021 Elsevier Ltd.

Recent advances in catalytic silylation of hydroxyl-bearing compounds: A green technique for protection of alcohols using Si-O bond formations

The development of catalytic silylation of alcohols under ambient reaction conditions plays an important role in organic synthesis. New silyl groups and methods for their introduction and removal are constantly being developed and offer chemists a wider range of options. In recent years, silyl protecting groups have been given expanded roles beyond their traditional use of temporarily rendering inactive alcohols. As silyl ether can be further converted to the parent alcohols in acidic conditions, silylation of alcohols can be regarded as an alternative method for hydroxyl protection under ambient reaction conditions. Merging the silyl protection/deprotection of alcohols with such modern methodologies, as green chemistry and nanoscience, has added additional value to these temporary components of synthetic intermediates. This review describes the historical background of the trimethylsilyl ethers preparation from alcohols using catalytic complexes and also the transformation of trimethylsilyl ethers into alcohol-containing compounds via deprecation techniques.
