Sustainable microalgae-based technology for biotransformation of benzalkonium chloride in oil and gas produced water: A laboratory-scale study

Many countries have implemented stringent regulatory standards for discharging produced water (PW) fromthe oil and gas extraction process. Among the different chemical pollutants occurring in PW, surfactants are widely applied in the oil and gas industry to provide a barrier from metal corrosion. However, the release of these substances fromthe shale formation can pose serious hazardous impacts on the aquatic environment. In this study, a low-cost and eco-friendly microalgae laboratory-scale technology has been tested for biotransformation of benzalkonium chloride (BAC(C12) and BAC(C14)) in seawater and PW during 14-days of treatment (spiked at 5 mg/L). From the eight microalgae strains selected, Tetraselmis suecica showed the highest removal rates of about 100% and 54% in seawater and PW, respectively. Suspect screening analysis using liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) allowed the identification of 12 isomeric intermediates generated coming from biotransformation mechanisms. Among them, the intermediate [OH-BAC(C12)] was found as the most intense compound generated from BAC(C12), while the intermediate [2OH-BAC(C14)] was found as the most intense compound generated from BAC(C14). The suggested chemical structures demonstrated a high reduction on their amphiphilic properties, and thus, their tendency to be adsorbed into sediments after water discharge. In this study, Tetraselmis suecica was classified as the most successful specie to reduce the surfactant activity of benzalkonium chloride in treated effluents. (c) 2020 The Authors.

S100A2 Silencing Relieves Epithelial-Mesenchymal Transition in Pulmonary Fibrosis by Inhibiting the Wnt/beta-Catenin Signaling Pathway

Pulmonary fibrosis (PF) is a progressive and lethal disease with poor prognosis. S100A2 plays an important role in the progression of cancer. However, the role of S100A2 in PF has not yet been reported. In this study, we explored the potential role of S100A2 in PF and its potential molecular mechanisms. Increased expression of S100A2 was first observed in lung tissues of PF patients. We found that downregulation of S100A2 inhibited the transforming growth factor-beta 1 (TGF-beta 1)-induced epithelial-mesenchymal transition (EMT) in A549 cells. Mechanically, TGF-beta 1 upregulated beta-catenin and the phosphorylation of glycogen synthase kinase-3 beta, which was blocked by silencing S100A2 in vitro. Furthermore, lithium chloride (activator of the Wnt/beta-catenin signaling pathway) effectively rescued S100A2 knockdown-mediated inhibition of EMT in PF. In conclusion, these findings demonstrate that downregulation of S100A2 alleviated PF through inhibiting EMT. S100A2 is a promising potential target for further understanding the mechanism and developing a strategy for the treatment of PF and other EMT-associated diseases.

Effect of dissolved oxygen on electrochemical corrosion behavior of 2205 duplex stainless steel in hot concentrated seawater

The corrosion behavior of 2205 duplex stainless steel was investigated in hot concentrated seawater with different dissolved oxygen (DO) concentration by electrochemical measurement techniques and surface analysis methods. DO obviously enhances the cathodic reaction process, the formation of passive film and polarization resistance. With increasing the DO concentration from 0.34 to 3.06 mg L-1, the relative contents of Fe2O3 and Cr2O3 and the Cr-enrichment gradually enlarge in the passive film. The higher DO concentrations result in lower defect densities and thicker of space charge layers in the passive films, which may effectively inhibit the intrusion of aggressive chloride ions. The increment in DO concentration clearly increases the pitting potential, but decreases the repassivation potential. It may weaken both the occurrence and repassviation tendencies of stable pitting corrosion.

Combination of solvent extraction with deep eutectic solvent based dispersive liquid-liquid microextraction for the analysis of aflatoxin M-1 in cheese samples using response surface methodology optimization

A new extraction procedure based on combination of a solvent extraction and deep eutectic solvent based dispersive liquid-liquid microextraction has been introduced for the extraction of aflatoxin M-1 from cheese samples. In this method, acetonitrile, deionized water, and n-hexane are added onto the sample and vortexed. Owning to different affinities of the substances in cheese toward the mentioned solvents, an efficient and selective extraction of the analyte is done in the acetonitrile phase. After centrifugation, the acetonitrile phase is removed and mixed with a new hydrophobic deep eutectic solvent prepared from N,N-diethanol ammonium chloride and carvacrol as an extraction solvent. The mixture is injected into deionized water, and a cloudy solution is obtained. Eventually, an aliquot of the organic phase is injected into high-performance liquid chromatography-fluorescence detection. After optimizing the effective parameters with the response surface methodology and a quadratic model, limits of detection and quantification were 0.74 and 2.56 ng/kg, respectively. The obtained extraction recovery and enrichment factor were 94% and 94, respectively. Also, intra- (n = 6) and interday (n = 4) precisions were less than or equal to 8.6% at a concentration of 5 ng/kg. The suggested method was applied to determine aflatoxin M-1 in different cheese samples.

Ultra-small molybdenum sulfide nanodot-coupled graphitic carbon nitride nanosheets: Trifunctional ammonium tetrathiomolybdate-assisted synthesis and high photocatalytic hydrogen evolution

The preparation of nanoscale molybdenum sulfide (MoS2)-modified graphitic carbon nitride (g-C3N4) nanosheets usually contains complex and multiple-step operations, including the separate synthesis of nanoscale MoS2 and g-C3N4 nanosheet, and their subsequent composite process. To effectively overcome the above drawbacks, herein, a facile one-step trifunctional ammonium tetrathiomolybdate ((NH4)(2)MoS4)-assisted approach has been designed to produce ultra-small MoSx nanodot-coupled g-C3N4 nanosheet photocatalyst, including the first addition of ammonium chloride (NH4Cl) and (NH4)(2)MoS4 into melamine precursors and their following one-step calcination. During high-temperature calcination, except for the promoting generation of the g-C3N4 nanosheets by produced ammonia (NH3) and hydrogen sulfide (H2S) gases, the above (NH4)(2)MoS4 decomposition not only can efficiently clip the s-heptazine framework to produce more terminal amino groups and cyano groups, but also can produce ultra-small MoSx nanodots on the resultant g-C3N4 nanosheet surface, resulting in the final production of ultra-small MoSx nanodot-coupled g-C3N4 nanosheets. The resultant MoSx nanodot-coupled g-C3N4 nanosheets evidently exhibit increased photocatalytic hydrogen (H-2)-generation rate, about 8-fold increase to the traditional MoS2-modified g-C3N4 photocatalyst. The ncreased H-2 -generation rate can be mainly attributed to the synergism of MoS x nanodots and cyano group on the g-C3N4 nanosheet surface. The current facile technology could open the sights for the preparation of other high-efficiency photocatalysts. (C) 2020 Elsevier Inc. All rights reserved.

Calcium-silicate-hydrate seeds as an accelerator for saving energy in cold weather concreting

Cold weather concreting is well-known for its high energy consumption and carbon emissions because it needs to take various measurements to prevent the frost damage of concrete. Effectively promoting the strength of concrete developed rapidly in cold weather is a crucial way to solve this problem. In this study, the chloride-free and green calcium-silicate-hydrate (C-S-H) seeds were used to modify the performance of Portland cement (PC) at the negative temperature. The results showed that the strength of PC adjusted by C-S-H seeds developed rapidly at negative temperature (-5 degrees C) within 28 d after several hours pre-curing; its strength value at 28 d (74.2 MPa) was comparable with that of PC cured at room temperature for 28 d (75.3 MPa). The addition of C-S-H seeds significantly accelerated the early hydration of PC during pre-curing and the subsequent hydration at negative temperature. The freezing point and the frozen water of cement paste were significantly reduced by C-S-H seeds and pre-curing, which can help to prevent the cement matrix from frost damage at -5 degrees C. This advantage was further demonstrated by the improvement of the microstructure caused by ice. The easy-operate and green method can significantly decrease energy consumption and CO2 emissions in cold weather concreting. (C) 2020 Elsevier Ltd. All rights reserved.

Blue Perovskite Light-Emitting Diodes: Opportunities and Challenges

Metal halide perovskites are considered as promising candidates for lighting applications owing to their excellent optoelectronic properties, such as high electron/hole mobility, high photoluminescence quantum yield, high color purity, and facile color tunability. In recent years, perovskite light-emitting diodes (LEDs) have developed rapidly, and their external quantum efficiencies (EQEs) have exceeded 20% for green and red emissions. However, the EQEs and stabilities of blue (particularly deep-blue) perovskite LEDs are still inferior to the green and red counterparts, which severely restricts the application of perovskite LEDs in high-performance and wide color gamut displays as well as white light illumination. Therefore, summarizing the development of blue perovskite LEDs and discussing the opportunities and challenges associated with their future applications will help to guide the further development of the entire perovskite LED field. In this review, according to the emission color, we divide the blue perovskite LEDs into three parts for a better discussion, i.e., the emissions in the sky-blue, pure-blue, and deep-blue regions. We introduce their developed history and discuss the basic strategies to achieve blue emission. There are three typical methods to obtain perovskite emitters with blue emission, i.e., (1) composition engineering, (2) dimensional engineering, and (3) synthesis of perovskite nanocrystals and quantum dots. For composition engineering, changing ions in perovskite ABX3 structure can easily tune the perovskite emission color, particularly while changing the anions in X position. Therefore, modulating the ratio between the X-site anions of Br- and a- can cause perovskites to emit blue photons ranging from 420 to 490 nm, which almost covers the entire blue spectrum. For dimensional engineering, perovskite materials can form a series of low-dimensional structures (layered structures) with the insertion of organic ligands between the perovskite frameworks. This type of low-dimensional perovskite material typically exhibits better lighting properties than those exhibited by its three-dimensional counterpart owing to its unique charge or energy transfer process of charge carriers. Blue perovskite nanocrystals and quantum dots with high photoluminescence quantum yields are excellent candidates for realizing high-performance pure-blue and deep-blue devices because they can easily incorporate a- in their crystals, which is considerably limited in perovskite thin films owing to the poor solubility of inorganic chloride sources in polar solvents. Furthermore, we discuss several challenges associated with blue perovskite LEDs, such as the inferior device performance in the pure-blue and deep-blue regions, difficulty in hole injection, electroluminescence (EL) instability of mixed halide perovskite systems, and lagged operation lifetime, and introduce potential solutions accordingly. Note that the challenges faced by blue perovskite LEDs are also the opportunities for research in this area. Therefore, this review is of a great reference value for the next evolution of blue perovskite LEDs.

NiFe2O4-rGO/ionic liquid modified carbon paste electrode: An amplified electrochemical sensitive sensor for determination of Sunset Yellow in the presence of Tartrazine and Allura Red

In this paper, using a carbon paste electrode (CPE) modified with 1-ethyl-3-methylimidazolium chloride as an ionic liquid (IL) and NiFe2O4-rGO nanocomposite (IL/NiFe2O4/rGO/CPE), a sensitive and effective electrochemical sensor is applied to analyze Sunset Yellow. The X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX) and Fourier-transform infrared spectroscopy (FTIR) are employed to characterize the synthesized NiFe2O4-rGO nanocomposite. The oxidation peak currents of colorants were obtained by CV and DPV techniques; and as a result, the two linear ranges from 0.05 to 30 mu M (R-2 = 0.9939) and 30 to 500 mu M (R-2 = 0.9953) along with LOD of 0.03 mu M for Sunset Yellow is obtained. The proposed sensor is successfully applied to determine the Sunset Yellow, Tartrazine and Allura Red in PBS (pH 3). The IL/NiFe2O4/rGO/CPE displays a high performance for analysis of these dyes in hair shampoo and an orange juice as real samples with acceptable results.

Neutralization inhibition mechanism of lithium nitrite and its effect on the microstructure of mortar

The effects of calcium nitrite on corrosion inhibition of rebar in concrete have been well established. Increase in compressive strength of concrete and decrease in penetration of chloride ion have been reported. However, the effect of lithium nitrite on durability of concrete is less understood. Hence, the performance of lithium nitrite against penetration of chloride ion and neutralization in mortar were experimented. Specimens containing lithium nitrite at different replacement ratio (0%, 5%, 12.5% and 25% of total mixing water) were cured under different conditions and subjected to accelerated neutralization. Ion analysis and characterization showed a substantial increase in neutralization inhibition with the addition of lithium nitrite. The decrease in calcium and increase in lithium ions were confirmed in the regions penetrated by carbon dioxide. Under any curing condition, 25% replacement of lithium nitrite showed the presence of Li+ concentration of about 40 mg/L around the specimen surface and more than 20 mg/L at all depths after promotion of neutralization. The internal pH of mortar was maintained at 12 or above for replacement ratio above 12.5% through the production of lithium hydroxide, even if calcium hydroxide was consumed by carbon dioxide. Both Li+ and moisture content affected the degree of neutralization inhibition. (C) 2020 Elsevier Ltd. All rights reserved.

Removal of rare-earth fission products from molten chloride salt used in pyroprocessing by precipitation for consolidation into glass-bonded sodalite waste form

As an alternative method to absorption into zeolite-A for removing rare-earth (RE) fission products (FPs) accumulated in spent molten chloride salt generated by the pyrometallurgical reprocessing of spent nuclear fuel, the precipitation of the RE FPs followed by consolidation into a glass-bonded sodalite waste form has been proposed to reduce the waste volume. Chemical forms of the precipitates generated by the addition of Li2O or Li2CO3 in LiCl-KCl melts containing chlorides of REs were identified. Then, the salt adhering to the Gd2O3 precipitate, which was generated by the addition of Li2O into LiCl-KCl molten salt containing GdCl3, was removed by vacuum distillation. The distillation product or its simulant (Gd2O3) was mixed with zeolite-A and fresh zeolite, and then consolidated into glass-bonded sodalite under uniaxial pressing at the maximum temperature and pressure of 915 degrees C and 1.3 x 10(5) Pa, respectively. Examinations of the consolidated products showed that a dense product was fabricated and that gadolinium existed as NaGd9Si6O26, as expected from the literature, or Gd2O3 in the products.
