An emulsion-templated and amino diol-dictated porous material as an efficient and well recyclable boric acid scavenger

A facile way to fabricate a pH-stable, durable, and porous material with active amines (NHx, x= 1,2)-derived diol groups on a pore surface is reported. Branched polyethyleneimine (PEI) in water forms a supramolecular complex with sodium dodecyl benzene sulfonate (SDBS), and this complex acts as an emulsifier. For the microcrystal cellulose (MC)-dispersed aqueous solution of PEI, SDBS is charged to turn the mixture into a medium internal phase air-in-water (A/W) emulsion upon oscillation. The emulsion is solidified by the partial crosslinking of PEI with polyethylene glycol diglycidyl ether (0.2 eq. of PEI NH groups) and further developed into an open-cellular monolith by removing the SDBS and water in the system. Under optimized conditions [pH 10, PEI at 20 % in water, and MC/PEI (50 % mass ratio)], the porous monolith (MC@PEI) shows a specific surface area of up to 14.9 m(2) g(-1). The amino groups are easily transformed into diols by treating with glycidol, and the resulting MC@PEI-diol can act as a scavenger to extract the trace boric acid in water. The adsorption follows the Langmuir model and shows chemical adsorption character with a boron-loading capacity of up to 2.68 mmol g(-1). Presaturing the scavenger with anionic dyes (488 mg g(-1)) exerts limited impact on the loading ability of BA. Additionally, the scavenger combines chemical stability in the absence of pH-labile bonds and mechanical durability for the composite structure with rigid MC skeleton and flexible PEI muscle.

Treatment of membrane concentrated leachate by two-stage electrochemical process enhanced by ultraviolet radiation: Performance and mechanism

Membrane systems are widely used for advanced leachate treatments in municipal waste incineration (MSWI) plants, resulting in the production of membrane concentrated leachate containing a high content of pollutants, especially refractory organics and salts. In this study, a two-stage electrochemical (TSE) process enhanced by ultraviolet (UV) radiation was applied to treat coagulated reverse osmosis concentrated leachate. Application of UV radiation throughout the TSE process produced remarkable results for pollutant removal because UV radiation promoted production of free radicals with strong oxidizing ability, which could function with active chlorine to oxidize pollutants, especially refractory organics. After the optimal UV-TSE (i.e., TSE process enhanced by UV radiation) treatment, the chemical oxygen demand, total organic carbon, light-absorbing substances (at 254 nm), ammonia nitrogen, and total nitrogen removal efficiencies were all more than 86%, and that of color, turbidity and chloride were more than 96%, which had better performance than TSE process. Following UV-TSE process, an obvious blue shift was observed in the UV-Vis spectra, with significant decrease in the absorbances in the UV region. The reduction in the intensity of peaks 1 and 2 in 3D fluorescence spectra was 87.37% and 88.90%, respectively. Flow field-flow fractionation analysis showed that the molecular weights of colored dissolved organic matter (DOM), humic-like DOM, and protein-like DOM deeply decreased. The UV-TSE treatment decomposed macromolecular organics into lower molecular organics more effectively and thoroughly, resulting in higher VOCs content in the treated sample, when compared with TSE-treated samples. These findings can shed light on the performance and organics removal mechanism of UV-TSE process, and provide a theoretical basis for the electrochemical treatment of membrane concentrated leachate from MSWI plants.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 320-51-4. Recommanded Product: 4-Chloro-3-(trifluoromethyl)aniline.

Genomic analysis of a functional haloacid-degrading gene of Bacillus megaterium strain BHS1 isolated from Blue Lake (Mavi Golu, Turkey)

Purpose: Bacillus megaterium strain BHS1, isolated from an alkaline water sample taken from Mavi Golu (Blue Lake, Turkey), can grow on minimal medium containing 2,2-dichloropropionic acid. We characterized this bacterium at the genomic level. Methods: The HiSeq platform was used to carry out genome sequencing, de novo assembly, and scaffolding with strain BHS1. Next, genome data were analyzed to demarcate DNA regions containing protein-coding genes and determine the function of certain BHS1 genes. Finally, results from a colorimetric chloride ion-release assay demonstrated that strain BHS1 produces dehalogenase. Results: De novo assembly of the BHS1 genomic sequence revealed a genome size of similar to 5.37 Mb with an average G+C content of 38%. The predicted nuclear genome harbors 5509 protein-coding genes, 1353 tRNA genes, 67 rRNA genes, and 6 non-coding (mRNA) genes. Genomic mapping of strain BHS1 revealed its amenability to synthesize two families of dehalogenases (Cof-type haloacid dehalogenase IIB family hydrolase and haloacid dehalogenase type II), suggesting that these enzymes can participate in the catabolism of halogenated organic acids. The mapping identified seven Na+/H+ antiporter subunits that are vital for adaptation of the bacterium to an alkaline environment. Apart from a pairwise analysis to the well-established L-2-haloacid dehalogenases, whole-cell analysis strongly suggested that the haloacid dehalogenase type II might act stereospecifically on L-2-chloropropionic acid, D,L-2-chloropropionic acid, and 2,2-dichloropropionic acid. Whole-cell studies confirmed the utilization of these three substrates and the gene’s role in dehalogenation. Conclusions: To our knowledge, this is the first report of the full genome sequence for strain BHS1, which enabled the characterization of selected genes having specific metabolic activities and their roles in the biodegradation of halogenated compounds.

Moisture re-adsorption characteristics of hydrochar generated from the Co-hydrothermal carbonization of PVC and alkali coal

Our previous work reported to simultaneously remove the alkali and alkaline earth metals, and chlorine by co hydrothermal carbonization (co-HTC) of high-alkali coal and polyvinyl chloride (PVC) (Fuel Process Technol, 199(2020)106277). This work is to investigate on the moisture re-adsorption characteristics of those hydrochar obtained at various co-HTC operating conditions. The results show that the water re-adsorption capacity of hydrochar was decreased with the circumstance temperature rising from 20 degrees C to 35 degrees C, while it was increased with the air humidity increasing from 50% to 80%. During the co-HTC, the addition of PVC could effectively inhibit the moisture re-adsorption behavior of hydrochar resulting from the adhere of the hydrophobic PVC to the surface of hydrochar as evidenced by SEM. The circumstance temperature had a significant influence on the effective diffusivity D over the humidity. The equilibrium moisture content (EMC) and effective diffusivity (D) could be linearly correlated with surface area and most probable pore size, respectively. The EMC of hydrochar was reduced about 0.6 mg/g as the BET surface area decreased 1 m(2). The reduction of oxygen-containing groups could reduce the adsorption equilibrium time and adsorption heat. Besides, the higher circumstance humidity would cause hydrochar to release higher adsorption heat. As the humidity was increased from 70% to 80%, the heat released by 1 g hydrochar was increased about 13.82-19.63 kJ/mol. Due to the lower EMC and adsorption heat, 300 degrees C was supposed to be a suitable temperature for the co-HTC to obtain hydrophobic hydrochar.

Spin-coated Cu2ZnSnS4 solar cells: A study on the transformation from ink to film

In this paper, we study the DMSO/thiourea/chloride salt system for synthesis of pure-sulfide Cu 2 ZnSnS 4 (CZTS) thin-film solar cells under ambient conditions. We map out the ink constituents and determine the effect of mixing time and filtering. The thermal behavior of the ink is analyzed, and we find that more than 90% of the solvent has evaporated at 250. C. However, chloride and sulfoxide species are released continually until 500. C, suggesting the advantage of a higher pre-annealing temperature, which is also commonly observed in the spin-coating routines in literature. Another advantage of a higher pre- annealing temperature is that the worm-like pattern in the spin-coated film can be avoided. We hypothesize that this pattern forms as a result of hydrodynamics within the film as it dries, and it causes micro-inhomogeneities in film morphology. Devices were completed in order to finally evaluate the effect of varying thermal exposure during pre- annealing. Contrary to the previous observations, a lower pre-annealing temperature of 250. C results in the best device efficiency of 4.65%, which to the best of our knowledge is the highest efficiency obtained for a puresulfide kesterite made with DMSO. Lower thermal exposure during pre-annealing results in larger grains and a thicker MoS 2 layer at the CZTS/Mo interface. Devices completed at higher pre-annealing temperatures display the existence of either a Cu-S secondary phase or an incomplete sulfurization with smaller grains and a fine-grain layer at the back interface.

Switching the solubility of electroactive ionic liquids for designing high energy supercapacitor and low potential biosensor

Ionic liquids are regarded as one of the most prodigious materials for sustainable technological developments with superior performance and versatility. Hence, in this study, we have reported the design and synthesis of electroactive disubstituted ferrocenyl ionic liquids (Fc-ILs) with two different counter anions and demonstrated the significance of their anion tuneable physicochemical characteristics towards multifunctional electrochemical applications. The Fc-IL synthesized with chloride counter anion (Fc-Cl-IL) displays water-solubility and can be used as a redox additive in the fabrication of supercapacitor. Supercapacitor device with Fc-Cl-IL based redox electrolyte exhibits outstanding energy and power densities of 91 Wh kg(-1) and 20.3 kW kg(-1), respectively. Meanwhile, ferrocenyl IL synthesized with perchlorate anion (Fc-ClO4-IL) exhibits water-insolubility and can serve as a redox mediator towards construction of a glucose biosensor. The biosensor comprising Fc-ClO4-IL is able to detect glucose at an exceptionally lower potential of 0.2 V, with remarkable sensitivity and selectivity. This study implies that the introduction of electroactive ILs could afford supercapacitor devices with high energy and power densities and biosensors with less detection potential.

Development of High-Level Omega-3 Eicosapentaenoic Acid (EPA) Production from Phaeodactylum tricornutum

Phaeodactylum tricornutum is a lipid-rich marine diatom that contains a high level of omega-3 polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA). In an effort to reduce costs for large-scale cultivation of this microalga, this study first established a New BBM medium (0.3 x strength BBM with only 3% of the initial phosphate level) to replace the traditional F/2 medium. Phaeodactylum tricornutum could grow in extremely low phosphate concentrations (25 mu M), without compromising the EPA content. In the presence of sea salts, silicate addition was not necessary for high rate growth, high EPA content, or lipid accumulation in this species. Using urea as the sole nitrogen source tended to increase EPA contents per dry biomass (by 24.7%) while not affecting growth performance. The use of sea salts, rather than just sodium chloride, led to significantly improved biomass yields (20% increase) and EPA contents of total fatty acid (46-52% increase), most likely because it supplied sufficient essential elements such as magnesium. A salinity level of 35 led to significantly higher biomass yields compared with 20, but salinity had no significant influence on EPA content. EPA became the dominant fatty acid with average levels of 51.8% of total fatty acids during the exponential growth phase at 20 ppt in New BBM medium with sea salts.

A green and highly efficient method of extracting polyphenols from Lilium davidii var. unicolor Salisb using deep eutectic solvents

It is important to find pollution-free, eco-friendly solvents to replace traditional organic solvents. As a new class of medium, deep eutectic solvents (DESs) provide a source of breaking through the green engineering barrier and bring new opportunities for extraction using green chemistry. In this research, the methods of polyphenol extraction from Lilium davidii var. unicolor Salisb with different types of DESs such as choline chloride, betaine, and tetrabutyl ammonium chloride-based DESs were investigated. Compared with traditional extraction solvent systems using methanol, DESs, which are composed of choline chloride and citric acid, have a higher extractive yield. The extraction conditions of polyphenol from Lilium davidii var. unicolor Salisb were studied; moreover, macroporous adsorptive resin was shown to be an efficient way in which to recover polyphenolic compounds. Recovery and reuse of DESs were also analyzed. DESs as green and designed solvent can be used to extract polyphenolic compounds from natural products.

Electrospun antibacterial poly(vinyl alcohol)/Ag nanoparticles membrane grafted with 3,3 ‘,4,4 ‘-benzophenone tetracarboxylic acid for efficient air filtration

In this study, poly(vinyl alcohol) (PVA) membranes containing Ag nanoparticles (AgNPs) were prepared by electrospinning and grafted copolymerization with 3,3′,4,4’-benzophenone tetracarboxylic acid (BPTA) to provide better mechanical properties, lower water vapor transmittance, and higher antibacterial activity (against Staphylococcus aureus and Escherichia coli) than the PVA/AgNPs membrane. The PVA/AgNPs/BPTA membrane showed higher antibacterial activity than the other membranes, and it produced inhibition zones with diameters of 18.12 +/- 0.08 and 16.41 +/- 0.05 mm against S. aureus and E. coli, respectively. The PVA/AgNPs/BPTA membrane was found to be capable of promoting reactive oxygen species (ROS) formation under both light and dark conditions. Cycling experiments performed following ROS quenching showed that the best-performing composite membrane retained> 70% of its original OH center dot radical and H2O2 charging capacity after seven cycles. In the filtration test, the electrospun nanofibrous membranes showed high filtration efficiencies of 99.98% for sodium chloride (NaCl). In addition, these membranes maintained a relatively low pressure drop of 168 Pa with a basis weight of 2.1 g m(-2). Thus, the PVA/AgNPs/BPTA membrane was concluded to be a promising medical protective material offering the benefits of structural stability and reusability.
