Effect of sodium chloride on the thermodynamic, rheological, and microstructural properties of field pea protein isolate/chitosan complex coacervates

The effect of increasing sodium chloride concentration (c(Na)(Cl), 0-0.4 M) on the formation and rheological and microstructural properties of field pea protein isolate (FPPI)/chitosan (Ch) complex coacervates was investigated. The maximum turbidity and zeta potential of FPPI/Ch mixtures consistently decreased with the increasing c(Na)(Cl). The tertiary conformation of FPPI was altered to facilitate the aggregation of FPPI/Ch complexes via hydrophobic interactions. Changes in thermodynamic parameters during the titration of FPPI with Ch confirmed the addition of NaCl could cause the inhibition of electrostatic complexation and the induction of non-Coulombic interactions. FPPI/Ch complex coacervates exhibited first enhanced and then weakened viscoelastic properties and an initially tightened and then a loosened microstructure as the c(Na)(Cl )increased. In summary, appropriate c(Na)(Cl) favors the formation of FPPI/Ch complex coacervates with improved functionalities via the coordination of promoted hydrophobic interactions and inhibited electrostatic attractions, facilitating the application of this protein ingredient in food development.

Solvometallurgical process for the recovery of rare-earth elements from Nd-Fe-B magnets

The protic ionic liquid pyridine hydrochloride is known to be a non-aqueous solvent for metal oxides, including rare-earth oxides. However, its application in extractive metallurgy and especially in solvent extraction has been so far limited by its miscibility with the aqueous phase. In this paper, molten pyridine hydrochloride (165 degrees C) was used to dissolve production scrap of Nd-Fe-B permanent magnets to recover the valuable metals neodymium and dysprosium. The Nd-Fe-B scrap powder completely dissolved in just 10 min with a lixiviant-to-solid ratio of 10 g g(-1). Afterwards, non-aqueous solvent extraction was performed at high temperature (165 degrees C) by using molecular extractants (PC-88A) or ionic liquids (Cyphos IL 101). The high temperature lowers the viscosity of the solvents, so that they can be used in undiluted form. Moreover, the high temperature affects the equilibrium constants and, hence, the distribution of the metals between the two phases. In the first stage, 30 vol% PC-88A in p-cymene was used to extract dysprosium(III), whereas in the second stage 100 vol% PC-88A was used to extract most of the neodymium(III). Finally, a mixture of Cyphos IL 101-p-cymene 70:30 (wt.:wt.) was shown to efficiently extract iron(II,III) from the concentrate leachate. A conceptual flowsheet was designed, which included the recycling of the pyridine hydrochloride to lower the costs and the environmental impact of the process.

Synthesis, characterization, crystal structure and bioactivity properties of the benzimidazole-functionalized PEPPSI type of Pd(II)NHC complexes

Herein, six new benzimidazole-functionalized Pd-based complexes bearing N-propylphthalimide group were synthesized. These new PEPPSI type of Pd(II)NHC complexes (PEPPSI: Pyridine Enhanced Precatalyst Preparation, Stabilization and Initiation) were prepared from the N-propylphthalimide substituted benzimidazolium salts, palladium chloride (PdCl2) and 3-chloropyridine. The structures of all (NHC)PdX2(3-chloropyridine) complexes have been clearly characterized by using NMR (H-1 and C-13), FTIR spectroscopic method, and elemental analysis techniques. Also, the structures of three of the (NHC)PdX2(3-chloropyridine) complexes were confirmed by single-crystal X-ray diffraction. Also, novel N-propylphthalimide-substituted (NHC)PdX 2 (3-chloropyridine) complexes effectively inhibited acetylcholinesterase (AChE), with Ki values in the range of 0.54 +/- 0.10 to 3.01 +/- 0.63 mu M. For butyryl-cholinesterase (BChE) was obtained with Ki values in the range of 0.82 +/- 0.11 to 5.03 +/- 0.86 mu M. For alpha-glycosidase (alpha-Gly) the most effective Ki values of 1c, 1d, and 1b were with Ki values of 23.83 +/- 5.98, 26.04 +/- 7.11, and 30.61 +/- 3.85 mu M, respectively. All novel N-propylphthalimide-substituted PEPPSI complexes and control compounds had almost similar inhibition profiles. (C) 2020 Elsevier B.V. All rights reserved.

Applications of UV/H2O2, UV/persulfate, and UV/persulfate/Cu2+ for the elimination of reverse osmosis concentrate generated from municipal wastewater reclamation treatment plant: Toxicity, transformation products, and disinfection byproducts

Reverse osmosis concentrate (ROC) resulting from treatment of municipal wastewater reclamation involves high concentrations of recalcitrant pollutants. This study evaluated the toxicity of an ROC containing harmful biocides during representative UV synergistic oxidation processes (SOPs) (e.g., UV/hydrogen peroxide (H2O2), UV/persulfate (PS), and UV/PS/Cu2+). Treated ROC exhibited up to 1.3-2.3 times higher toxicity than the parent compounds such as dodecyl trimethyl ammonium chloride (DTAC) and dodecyl dimethyl benzyl ammonium chloride (DDBAC). Based on the intermediates identification, the major toxic intermediates were screened through silico assessment using the quantitative Ecological Structure-Activity Relationship (ECOSAR) tool. The transformation products (TPs) of hydroxylation and ketonization were the major formed reactions from the UV/PS/Cu2+. Also, some cytotoxic TPs were accumulated during the UV/H2O2 and UV/PS oxidations, where the carbonaceous-disinfection byproducts were more than the nitrogenous-disinfection byproducts. In the presence of chloride and bromide, chlorate and bromate could be formed during the UV-SOP; they were influenced by the different water matrix in comparison with the different ROC. Also, the formation of the total organic halogen species (TOX) was found to follow this order: UV/PS/Cu2+< UV/H2O2 < UV/PS. In this study, the predicted cytotoxicity using the correlation between the TOX and the cytotoxicity was more acceptable than that of the cytotoxicity index method. Further, the R-square of the correlation between the TOX and the cytotoxicity for the UV/H2O2 and UV/PS was 0.82 and 0.79, respectively. The predicted cytotoxicity using the TOX correlation method in the ROC could also be used to monitor and prevent the application of different oxidations inmunicipal wastewater reclamation treatment plants.

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.

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.

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.

Paper-Based Enzyme Biosensor for One-Step Detection of Hypoxanthine in Fresh and Degraded Fish

Food freshness monitoring, which can reflect the quality of the product at the time of use, remains a great challenge for consumers and the food industry. Herein, we report the development of a cost-effective enzyme-based paper biosensor, which can monitor fish freshness and predict spoilage. The biosensor measures the release of hypoxanthine (HX), an indicator of meat and fish degradation, using the enzymatic conversion of HX by xanthine oxidase (XOD). We demonstrate that the entrapment of XOD and an organic dye, nitro blue tetrazolium chloride (NBT), within a sol-gel biohybrid enables their stabilization on paper and promotes the enzymatic reaction with further retention of the reaction products within the cellulosic network . Linearity in the micromolar concentration range with a detection limit of 3.7 mu M for HX is obtained. The biosensor has high selectivity toward HX and is manufactured in few steps from inexpensive widely available materials. The applicability of the biosensor is demonstrated by following fish degradation over time and measuring HX concentrations ranging from 117 (+/- 9) to 198 (+/- 5) mu M within 24 h of degradation, at levels that are comparable with those measured by a commercial enzymatic kit for HX detection. As compared to the commercial kit, our biosensors are more cost-effective, do not require addition of exogenous reagents and are portable, having all of the reagents needed for analysis embedded within the sensing platform. This proof-of-concept work demonstrates that the paper-based HX biosensor has potential as a robust reagentless device for real-time monitoring of food freshness and for other applications in which HX plays an important role.
