Chloride gradient render carrier extraction of hole transport layer for high V-oc and efficient inverted organometal halide perovskite solar cell

A carrier transport layer and its interfacial effects on an organometal halide perovskite light harvesting layer play an influential factor in either photovoltaic performance or long-term stability of a perovskite solar cell (OHPSC). Although the understandings of the carrier transport layers and interfacial effects on regular structured OHPSCs have been explored, knowledge of an interface between hole transport layer of NiOx and perovskite in an inverted OHPSC is still necessary to be developed. Here, we performed a universal NiOx film with the sequential passivation strategy of NiCl2 (SPS-NiCl2 treatment) for either wide bandgap or narrow bandgap of OHPSCs. The SPS-NiCl2 treated NiOx film not only implements the passivation at the perovskite layer/NiOx film interface but also confers itself a gradient energy level of valance band inducing by chloride. Comprehensive characterizations reveal that the SPS-NiCl2 treated NiOx film suppresses non-radiative recombination at the interface and enlarges the splitting of the quasi-Fermi level at the interfaces. The photoconversion efficiency (PCE) of the champion device comprised of the SPS-NiCl2 treated NiOx film can achieve 19.53% with a record V-oc of 1.16 V, the lowest V-oc deficit of 390 mV in NiOx based inverted OHPSCs. The corresponding devices with encapsulation also exhibit superior long-term stability, and over 80% of initial PCE can be maintained after 1500 h damp-heat test. This study sheds the light on managing the interfacial issues of an inverted OHPSC and offers a feasible path to develop a universal hole transport layer for perovskite layers with different energy bandgap.

Association of Salt Iodization and Urine Iodine Concentration in Schoolchildren from Public Schools in Northeast of Brazil

Iodine deficiency (ID) is recognized as a leading risk factor for child development. Universal salt iodization (USI) is an effective and well-established intervention strategy for the prevention of iodine deficiency disorders (IDD). To evaluate the levels of iodine in household salt samples and the urinary iodine concentration (UIC) in schoolchildren aged 6 to 14 years in public schools in Bahia, Brazil. A cross-sectional study was conducted with 1231 students (6 to 14 years old) from 17 public schools in Bahia. The iodine concentration was evaluated in salt and UIC samples. The adapted Sandell-Kolthoff reaction was used to determine urinary iodine levels. A spectrophotometer (UV-Vis) was used to examine the reduction of ceric ammonium sulfate. A standard iodine solution using a potassium iodate was used to extrapolate the iodine concentrations. The total of 665 salt samples had a median iodine concentration of 24 mg/kg (25th-75th percentile 17.0 to 28.5 mg/kg). The largest proportion (79.6%) of salt samples had iodine concentration in the recommended range, 17.6% of the samples presented iodine at a salt concentration below the established level (<15 mg/kg) and a small proportion was above it (2.8%). The general mean urinary iodine concentration (MUIC) was 217.53 +/- 28.30 mu g/L and median was 205.50 mu g/L. The students evaluated and the salt samples analyzed showed satisfactory results, as recommended by Brazilian legislation and nutritional recommendations of the World Health Organization (WHO). But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6276-54-6, you can contact me at any time and look forward to more communication.

Strategic biorefinery platform for green valorization of agro-industrial residues: A sustainable approach towards biodegradable plastics

The production of cellulose reinforced bio-composites has emerged as an efficient bio-sustainable alternative for high-quality functional polymeric materials to replace the presently dominated petroleum-based plastics. Also because, lignocellulose biorefinery from waste agro-industrial residues has attracted widespread attention for combating increasing environmental pollution caused by incineration of such wastes. In this prospect, the fractionation of tender coconut husks (TCH) to yield cellulose, hemicellulose and lignin fractions has been investigated by different pretreatment methodologies using conventional and novel reaction media. Excellent outcomes were obtained with the use of the deep eutectic solvent composed of choline chloride and oxalic acid dihydrate that led to the dissolution of 95.5% of the initial lignin in TCH to yield a cellulose fractional recovery of 87.5% at the optimal conditions attained by parametric variations. Interestingly, the same eutectic mixture also functionalized the obtained cellulose to cellulose nanocrystals (CNC) with 69% yield, crystallinity index of 88.6% and average particle size of 146 nm. Further, isolated starch from waste tamarind seeds was used as the polymer matrix wherein the CNC was added as a suitable bio-filler to cast bioplastic films using biodiesel byproduct glycerol as a plasticizer. The characterization of the biodegradable films revealed a tensile strength of 21.8 MPa along with outstanding thermal and moisture barrier properties. The results elucidate that the huge dependence for petro-plastics could be reduced with the integrated valorization of solid wastes that can aid wide-ranging industries and align with the rising motto of a bioeconomy.

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.

Enzyme Inhibitory Kinetics and Molecular Docking Studies of Halo-Substituted Mixed Ester/Amide-Based Derivatives as Jack Bean Urease Inhibitors

A series of halo-substituted mixed ester/amide-based analogues 4a-l have been prepared as jack bean urease inhibitor, which showed good to excellent inhibition of enzyme activity. The role of halo-substituted benzoyl moieties and alkyl substituted anilines in urease inhibitory kinetics was also investigated. The alkyl-substituted anilines 1a-b reacted with chloroacetyl chloride to afford intermediates 2a-b, which were then reacted with different halo-substituted benzoic acids 3a-f to prepare the title compounds 4a-l. The chemical structures of final products 4a-l were ascertained by FTIR, H-1 NMR, C-13 NMR, and mass spectra. The compound 4b showed remarkable activity with IC(50)1.6 +/- 0.2 nM, better than the standard thiourea having IC(50)472.1 +/- 135.1 nM. The 2-chloro-substituted phenyl ring on one side of compound 4b and 4-isopropyl-substituted benzene on the other side play an essential role in inhibition of urease activity. Lineweaver-Burk plots (kinetics study) indicated about 4b derivative as a mixed type of inhibitor. The virtual screening performed against urease enzyme (PDBID 4H9M) showed that compounds 4b and 4e have binding energies of -7.8 and -7.9 Kcal/mol, respectively. Based upon our results, it was found that derivative 4b is a highly potent urease inhibitor, better than the standard thiourea.

Novel green manufacture of metallic aluminum coatings on carbon steel by sol-gel method

Industrial processes for fabricating hot-dipping aluminum coatings on carbon steels involve problems related to equipment complexity, environmental issues and high energy consumption. To address these problems, a novel method for manufacturing metallic aluminum coating on carbon steel Q235 at room temperature by sol-gel method was developed in this work. Both the single-layer coating (47 mu m) and the double-layer coating (97 mu m) specimens were prepared by spraying some aqueous silica sol slurries containing spherical and flaky micro metallic aluminum powders on the steel surface at room temperature and then drying them at 50 degrees C. When the two coating specimens were heated at 500 degrees C for 10 h, heated double-layer specimens were thus obtained. It was found that the double-layer and the heated double-layer specimens didn’t rust at all after being soaked in aerated 3.5 wt% NaCl for 30 days. The shielding effect of the compact top coating was the main anticorrosion mechanism of the double-layer coating based on some electrochemical impedence spectroscopies and potentiodynamic polarization curves. Both coatings comprised only one metallic Al phase based on XRD. A very small quantity of Al2O3 phase appeared only after heating both coating specimens at 500 degrees C in the air for 10 h. In both cases the coatings didn’t crack at all after being heated at 500 degrees C in the air for 15 h by SEM observation and the oxidation rates of the steel substrates under these conditions were reduced by over 72% owing to the presence of the coatings. The average adhesive strengths of the single-layer and double-layer Al coatings were 12.06 MPa and 11.23 MPa, respectively, which were much larger than the corresponding value (max 8 MPa) of an ordinary anti-rusting epoxy coating on Q235 steel. Compared to the conventional hot-dipping aluminum or aluminized process, this novel method eliminates all the high temperature processes and thus saves a lot of energy, eliminates the use of all hazardous fluorides or chlorides and explosive H-2, avoids the formation of the voids inside aluminized coating, reduces the hot-dipped Al coating defects, can be applied for the steel plates with over 0.8 mm thickness, and can be applied in situ to repair damaged Al or Zn coatings.

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.

Cellular toxicology and mechanism of the response to silver-based nanoparticle exposure in Ewing’s sarcoma cells

Ewing’s sarcoma is the most aggressive connective tissue tumor, mainly affecting children and adolescents; the 5 year survival rate is only 50%. Current treatments have poor effectiveness, and more efficient treatments are being sought. Silver-based nanoparticles, such as silver chloride nanoparticles (AgCl-NPs) and silver/silver chloride (Ag/AgCl-NPs) nanoparticles, can be biologically produced and can release Ag+ ions into solution; however, their antitumor activity has been minimally investigated. The aim of this study was to evaluate the antitumor potential of AgCl-NPs and Ag/AgCl-NPs against Ewing’s sarcoma cells. A673 cells (Ewing’s sarcoma) were treated for 72 h with 0-12.5 mu g ml(-1) of Ag/AgCl-NPs or 0-40 mu g ml(-1) of AgCl-NPs. Human cells from the RPE-1 cell line (pigmented retinal epithelium) were used as a model of nontumor cells. The RPE-1 cells were less affected by the administration of AgCl-NPs or Ag/AgCl-NPs, with small reductions in the number of cells and viability and a small increase in apoptosis rates, while lysosomal damage, changes in reactive oxygen species (ROS) production, loss of mitochondrial membrane potential and alterations in microfilaments or cell areas were not observed. A673 tumor cells had significantly reduced number and viability levels when treated with AgCl-NPs, with reductions of 65.05% and 99.17%, respectively, whereas with Ag/AgCl-NP treatment, reductions of 65.53% and 92.51% were observed, respectively. When treated with silver-based nanoparticles, A673 cells also showed a significant increase in ROS production and loss of mitochondrial membrane potential, which culminated in an increase in the percentage of apoptosis among the population. Lysosomal damage was also observed when A673 cells were treated with the highest concentration of AgCl-NPs. In conclusion, the results showed that both AgCl-NPs and Ag/AgCl-NPs had some antitumor activity with minimal effects against healthy cells, which demonstrated the possibility of their use in cancer therapy.

Extraction of Au(III) using aromatic ethers via ion solvation from acidic chloride media: Structural factors that influence extraction

Ethereal compounds, such as the commercially available extractant dibutyl carbitol (DBC), can extract Au(III) from acidic chloride media by ion solvation. Herein, various aromatic ether compounds comprising an aromatic ring and aliphatic chains were prepared to compare the extraction affinity toward Au(III) without dilution. Aromatic monoethers are not useful for the extraction of Au(III). Conversely, the extraction of Au(III) using aromatic 1,2-diethers increases as a function of hydrochloric acid concentration. For aromatic 1,2-diethers, the shorter the aliphatic chain, the higher the extraction affinity toward Au(III). 1,2-Dimethoxybenzene (o-DMB), which has the shortest side chains, exhibits the highest extraction affinity. 1,3-Dimethoxybenzene (m-DMB), which is a regioisomer for o-DMB, was not suitable for the extraction of Au(III). The extraction selectivity toward Au(III) over that of Fe(III) and Ga(III) using o-DMB, under high concentrations of hydrochloric acid, is higher than that using DBC. Selected aromatic 1,2-diethers, including o-DMB, show a significantly higher extraction capacity toward Au(III) than the industrial requirement of 30 g/dm(3). Au(III) extracted using o-DMB was quantitatively recovered by reduction with oxalic acid. In a separation test from a mixed system comprising seven metals, Au(III) was selectively extracted and with a recovery percentage, after reduction, reaching 95.7%.
