Full color emission of all-bromide inorganic perovskite nanocrystals

Inorganic perovskites have attracted intensive research attention. The perovskites ABX(3) (X = Cl, Br, and I) can be used for blue, green, and red emission by adjusting the halogen X. However, it is very hard to avoid halogen exchanging when different halide perovskites are used together for optoelectronic devices. We synthesized the all-bromide inorganic perovskite nanocrystals with full color emission. The blue emission with a center wavelength of 405nm originates from the exciton recombination through the charge-transfer exciton state in perovskite Cs4PbBr6. The green emission with a center wavelength of 520nm results from band edge-exciton recombination in perovskite CsPbBr3. The red emission with a center wavelength of 606nm comes from the trapped- and self-trapped-exciton recombination in perovskite CsPb2Br5. Our experimental results show that all-bromide inorganic perovskite nanocrystals have great potential for full color light emitting devices.

Fast chemical recycling of carbon fiber reinforced plastic at ambient pressure using an aqueous solvent accelerated by a surfactant

The properties of infusibility and insolubility in organic solvent of cured epoxy resin makes it difficult to recycle carbon fiber reinforced plastics (CFRP). We have reported the recycling of CFRPs using the oxidizing power of hydroxyl radicals generated from NaOCl solution. In our study, we used benzyltrimethylam-monium bromide (BTAB) and sodium dodecyl sulfate (SDS) for the interfacial separation between the epoxy resin and carbon fibers (CF). The surfactant system maximized recycling efficiency in both pretreatment and the main reaction of the CFRP recycling process. In the second step, the reaction time to successfully reclaim the CFs was much shorter, only one hour, compared with the two-hour reaction time for the non-SDS process previously reported by us. Scanning electron microscope images and Raman analyses showed that the surface of the reclaimed CF (r-CFs) was clean and smooth without any defects, and there was no significant structural change compared to virgin CF (v-CFs). The tensile strength of r-CF was 3.42 GPa which is 96.9% of the v-CF. Thus, the CFRP recycling process using SDS not only results in r-CF with good mechanical and physical properties, but also increases recycling efficiency by reducing the time. (C) 2020 Elsevier Ltd.

Oxalic Acid Monothioester for Palladium-Catalyzed Decarboxylative Thiocarbonylation and Hydrothiocarbonylation

Oxalic acid monothioester (OAM), an easily accessible and storable reagent, was reported herein as a thioester synthetic equivalent for palladium-catalyzed decarboxylative thiocarbonylation of organohalides and hydrothiocarbonylation of unsaturated carbon-carbon bonds at room temperature with high chemo- and regioselectivity. The reaction is applicable to the synthesis of cysteine-derived thioesters, thus allowing chemical modification of cysteine-containing peptides. Decarboxylation of OAM proceeds through oxidative addition of Pd(0) to the acyl-S bond, which accounts for the very mild reaction conditions.

Development of a rat and human PBPK model for bromate and estimation of human equivalent concentrations in drinking water

A physiologically based pharmacokinetic (PBPK) model was developed to described uptake, disposition and clearance of bromate in the rat using published experimental data in rat. The rodent bromate model was extrapolated to human using species-specific physiological parameters and standard interspecies scaling of rate constants. The bromate model is kinetically linear (i.e. AUC and Cmax) across the range of drinking water concentrations used in the cancer bioassays (15 to 500 ppm). This is likely the result of the poor oral bioavailability of bromate due to high reduction rates in the intestinal tract. The bromate PBPK model was used to assess the human equivalent drinking water concentration (HEC) consistent with average plasma concentrations in the rodent bioassays. At drinking water concentrations <500 mg/L, the predicted HEC was two to three fold lower than the bioassay concentration and was dependent on the reported drinking water intake reported in the bioassay.

Synthesis of benzotriazoles derivatives and their dual potential as alpha-amylase and alpha-glucosidase inhibitors in vitro: Structure-activity relationship, molecular docking, and kinetic studies

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

Microwave-assisted pyrolysis of organometallic gel prepared through ternary combination of surfactants for fabrication of nano-porous gamma alumina: adsorptive properties, characterization

BACKGROUND In present work, gamma-Al2O3 nanoparticles, with uniform morphology and controllable size, were successfully fabricated by the microwave-assisted pyrolysis of organometallic gels prepared through the application of aluminum nitrite, urea, glycine, and triple mixed surfactants. A series of pyrolysis reactions were carried out by the conventional and microwave treatments to achieve nano-porous powders. The effects of different process factors, such as fuel composition, pyrolysis method, calcination temperature, and surfactant mixing ratio, on the adsorptive properties and physico-chemical characteristics of powders were investigated. RESULTS gamma-Al2O3 nanoparticles (10-20 nm) were successfully synthesized through optimized process variables. Although the calcination temperature is a significant variable in altering adsorptive properties, microwave pyrolysis causes a reduction in the calcination temperature (700 degrees C). Cetyl trimethyl ammonium bromide (CTAB), which is a cationic surfactant, mixed with a non-ionic surfactant (Triton-X-100) can produce nano-sized gamma-Al2O3 particles. The stoichiometric aluminum nitrate-urea admixed with surfactants produced a powder with higher specific surface area, 238 m(2) g(-1), which is comparable with that obtained via the salt-urea-glycine system. CONCLUSION Though mesoporous powder with a large surface area can be synthesized by urea-glycine system, the employment of triple surfactant system admixed with urea may be a reliable route to produce mesoporous powder economically.

Electrochemical CO2 Fixation to alpha-Methylbenzyl Bromide in Divided Cells with Nonsacrificial Anodes and Aqueous Anolytes

Electrocarboxylation of organic halides represents a CO2 utilization strategy and a green alternative for the synthesis of many industrially relevant carboxylic acids. However, current electrocarboxylation methods rely on the utilization of sacrificial metal anodes, which are not sustainable, require high voltages, and complicate the understanding of the reaction mechanism. Here, we demonstrate the feasibility of performing electrocarboxylation reactions in divided cells with aqueous anolytes and nonsacrificial anodes, thereby eliminating the reliance on sacrificial anodes and opening the door for coupling of this important reduction process with various electrooxidation reactions requiring aqueous electrolytes. Specifically, we report a detailed study of electrocarboxylation of (1-bromoethyl)benzene at a silver cathode coupled with an oxygen evolution reaction at a platinum anode in a divided cell with organic and aqueous compartments separated by ion-exchange membranes of different types. We examine how operating parameters, including membrane type, applied potential, substrate concentration, electrolyte, and temperature affect the overall process and the reaction product distribution. Based on the extensive experimental results, we propose a detailed mechanism for major electrochemical product formation accounting for both aprotic and protic environments. Systematic analysis and mechanistic insights presented in this study are expected to enable a rational catalyst, electrolyte, and system design tailored to electroorganic CO2 fixation with different organic substrates to obtain industrially relevant carboxylic acids at practical potentials and currents.

Combination of SDF-1 and bFGF promotes bone marrow stem cell-mediated periodontal ligament regeneration

Stromal cell derived factor-1 (SDF-1) and basic fibroblast growth factor (bFGF) were reported to induce the differentiation of bone marrow stem cells (BMSCs) into cells with characteristics of periodontal ligament fibroblasts. Thus SDF-1 and bFGF may play a positive role in BMSCs-mediated periodontal ligament regeneration. Here, the methylthiazolyldiphenyl tetrazolium bromide (MTT) assay was used to investigate the effect of scaffolds, SDF-1 and bFGF on BMSCs proliferation. RT-PCR and Western blot were used to evaluate gene and protein expression. Beagle dogs were used to establish an animal model of tooth reimplantation and to investigate the effects of scaffolds, BMSCs, SDF-1 and bFGF on periodontal ligament regeneration. X-ray images and micro computed tomography (micro CT) were used to assess morphological changes in replanted teeth and surrounding alveolar bone. H&E staining and Masson’s staining were also performed. BMSCs from Beagle dogs growth on scaffolds consisted of dense structured collagens. SDF-1 and bFGF effectively promoted the differentiation of BMSCs into fibroblasts, periodontal membrane reconstruction, and cell proliferation in vitro. SDF-1 and bFGF also stimulated the expression of type I collagen (Col I), type III collagen (Col III), CXC family chemokine receptor 4 (CXCR4), and S100 calcium binding protein A4 (S100A4), and decreased the expression of alkaline phosphatase (ALP). In our experimental Beagle dog model of tooth extraction and replantation, application of SDF-1 and bFGF significantly elevated periodontal membrane reconstruction and thus supported the survival of replanted teeth. In conclusion, the findings from the present study demonstrated that SDF-1 and bFGF enhance the process of periodontal ligament reconstruction, and provide a basis and reference for the use of stem cell tissue engineering in promoting periodontal membrane regeneration.

Nischarin downregulation attenuates cell injury induced by oxidative stress via Wnt signaling

Nischarin (NISCH) is a key protein functioning as a molecular scaffold and thereby hosting interactions with several protein partners. Here, we aimed to investigate whether NISCH downregulation could protect rat pheochromocytoma (PC12) cells against oxidative stress-induced injury using a model of cell injury induced by hydrogen peroxide (H2O2). Cell viability was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Cell apoptosis rate was evaluated using flow cytometry. The expressions of apoptosis-related proteins Bax, Bcl-2, caspase-3 and NISCH were examined via Western blot analysis and immunofluorescence staining analyses. The expressions of NISCH, glycogen synthase kinase-3 beta (GSK-3 beta) and T-cell factor-1 (TCF-1) were examined using Western blot analysis. The results showed that incubation of H2O2 for 48 h significantly decreased the cell viability, increased the cell apoptosis rate and the NISCH expression in PC12 cells, whereas NISCH downregulation blocked the effects of H2O2 on cells. In addition, the expression of Bcl-2 was significantly reduced, and the expression of Bax and caspase-3 were significantly increased by H2O2 treatment. However, these effects were partially inhibited by the downregulation of NISCH. Furthermore, H2O2 significantly weakened the transduction of Wnt signaling, including the increases of GSK-3 beta and TCF-1 expressions and the decrease of beta-catenin expression, while NISCH downregulation attenuated the effect of H2O2 on Wnt signaling. Moreover, inhibition of the Wnt pathway further decreased the cell viability and promoted the cell apoptosis induced by H2O2 in PC12 cells. Our results suggest that NISCH downregulation may protect cells against oxidative stress-induced injury through regulating the transduction of Wnt signaling.
