Structure and Optical Properties of Layered Perovskite (MA)(2)PbI2-xBrx(SCN)(2) (0 <= x < 1.6) The layered perovskite (MA)(2)PbI2(SCN)(2) (MA = CH3NH3+) is a member of an emerging series of compounds derived from hybrid organic-inorganic perovskites. Here, we successfully synthesized (MA)(2)PbI2-xBrx(SCN)(2) (0 <= x < 1.6) by using a solid-state reaction. Despite smaller bromide substitution for iodine, 1% linear expansion along the a axis was observed at x similar to 0.4 due to a change of the orientation of the SCN- anions. Diffuse reflectance spectra reveal that the optical band gap increases by the bromide substitution, which is supported by the DFT calculations. Curiously, bromine-rich compounds where x >= 0.8 are light sensitive, leading to partial decomposition after similar to 24 h. This study demonstrates that the layered perovskite (MA)(2)PbI2(SCN)(2) tolerates a wide range of bromide substitution toward tuning the band gap energy.

A Streamlined Regenerative Glycosylation Reaction: Direct, Acid-Free Activation of Thioglycosides

Our group has previously reported that 3,3-difluoroxindole (HOFox) is able to mediate glycosylations via intermediacy of OFox imidates. Thioglycoside precursors were first converted into the corresponding glycosyl bromides that were then converted into the OFox imidates in the presence of Ag2O followed by the activation with catalytic Lewis acid in a regenerative fashion. Reported herein is a direct conversion of thioglycosides via the regenerative approach that bypasses the intermediacy of bromides and eliminates the need for heavy-metal-based promoters. The direct regenerative activation of thioglycosides is achieved under neutral reaction conditions using only 1 equiv. NIS and catalytic HOFox without the acidic additives.

Micelles of Mesoporous Silica with Inserted Iron Complexes as a Platform for Constructing Efficient Electrocatalysts for Oxygen Reduction

Iron, N-codoped carbon materials (Fe-N-C) are promising electrocatalysts toward oxygen reduction reactions due to their high atom utilization efficiency and intrinsic activity. Nanostructuring of the Fe-N-C materials, such as introducing porosity into the carbon structure, would be conducive to further increasing the exposure of active sites as well as improving the mass transfer. Herein, we explore the potential of iron complexfunctionalized micelles of mesoporous SiO2 as a platform for constructing porous Fe-N-C materials. The classical three-dimensional MCM-48 was selected as a proof-of-concept example, which was utilized as the hard template, and cetyltrimethylammonium bromide micelles inside it played the role of the main carbon source. Fe-N-x sites were derived from Fe-1,10-phenanthroline complexes in the micelles introduced by in situ incorporation of 1,10-phenanthroline and post Fe2+ insertion in an aqueous solution. After thermal annealing in a nitrogen atmosphere and subsequent removal of the MCM-48 framework, a carbon material that possesses porous structural features with uniformly dispersed Fe-N-x sites (MPC@PhFe) was obtained, which shows superior ORR activity in a 0.1 M KOH solution and great potential for Zn-air battery applications as well. This work demonstrates the feasibility as well as the effectiveness of turning micelles of mesoporous SiO2 into porous carbon structures and might offer a universal strategy for manufacturing carbon materials for future application in energy storage and conversion.

Damage and Phenotype Change in PC12 Cells Induced by Lipopolysaccharide Can Be Inhibited by Antioxidants Through Reduced Cytoskeleton Protein Synthesis

The present study investigated changes in cellular phenotype and oxidative stress during the inflammatory response in PC12 cells stimulated by lipopolysaccharide (LPS) and assessed the effects of minocycline, astragalus (AST), and baicalin on inflammation. PC12 cells were exposed to LPS with or without minocycline, AST, or baicalin. Cell viability was measured by a thiazolyl blue tetrazolium bromide (MTT) assay. Contrast and laser confocal microscopy were used to analyze changes in cellular phenotype and cytoskeleton synthesis. Western blotting tested the expression of alpha 7nAChR and vimentin. Inhibitory ratio of superoxide dismutase (SOD) activity and leakage of lactate dehydrogenase (LDH) were detected to evaluate cellular oxidative stress. Results showed that LPS could attenuate PC12 cell viability in a time- and dose-dependent manner, which could be rescued by minocycline. In addition, minocycline could reverse PC12 cell phenotypic change and the synthesis of the mesenchymal cytoskeleton protein vimentin, both induced by LPS. During LPS-initiated inflammation, alpha 7nAChR and vimentin expression were obviously inhibited by minocycline, AST, or baicalin. The inhibitory rate of SOD activity and LDH leakage in PC12 cells were increased by LPS and attenuated significantly when exposed to minocycline, AST, or baicalin. These findings suggest phenotype change, altered cytoskeleton protein synthesis, and oxidative stress are all involved in the inflammatory response in PC12 cells during which alpha 7 nicotinic acetylcholine receptor (alpha 7nAChR) is induced by LPS stimulation. Minocycline, AST, and baicalin have a protective effect against PC12 cell injury, acting as antioxidants and inhibitors of mesenchymal proteins.

Simultaneous fabrication of carbon nanodots and hydroxyapatite nanoparticles from fish scale for biomedical applications

Fish industries and markets produce large quantities of fish scales, skins, shells, and bone wastes post processing that contaminate the environment and cause health risks in humans. In this context, we have developed a novel and simple integrated process to valorize the Lethrinus lentjan fish scales by fabricate carbon nanodots (CDs) and hydroxyapatite nanoparticles (HA NPs) simultaneously. The fish scale treatment was carried out by hydrothermal method at 280 degrees C that produced CDs and HA NPs simultaneously. Under hydrothermal treatment, organic and inorganic substances of fish scale is transformed to CDs and HA NPs respectively. As TEM images confirmed that fish scale derived CDs were spherically shaped and similar to 3 to 15 nm in size. The CDs exhibited excitation-dependent emission in photoluminescence. The HA NPs were similar to 8 to 12 nm in diameter and similar to 50 to 100 nm in length with rod shape. Also, HA NPs possess spherical shape nanostructures with 15-50 nm in diameter. Furthermore, we assessed the cytotoxic behavior of synthesized nanostructures using the MTT assay and acridine orange/ethidium bromide (AO/EB) staining. These results showed that synthesized CDs and HA NPs did not cause significant changes in cell viability and morphology, indicating biocompatibility. Additionally, the synthesized CDs and HA NPs were exploited as fluorescent probes for cellular imaging and osteogenic differentiation of stem cells respectively. Overall, the study results indicate that low-cost fish waste was valorized by producing CDs and HA NPs concurrently. The synthesized nanostructures can be applicable for bio-imaging and bone tissue engineering applications.

Formation and potential application of micelles composed of biocompatible N-lauroyl-amino acid ionic liquids surfactant

Surface-active ionic liquid (SAIL) surfactants have attracted attention as promising alternatives to conventional surfactants because of their tailor-made and tunable properties. SAILs also address the limitations associated with conventional surfactants including toxicity and formation of unstable micelles. Here, we investigated the aggregation behavior of three biocompatible choline N-lauroyl-amino add (NIAA)-based ILs with different amino acid side chains in aqueous solutions. The micellar behaviors of NLAA-ILs were investigated using surface tensiometry, conductometry, dynamic light scattering (DLS) and transmission electron microscopy (TEM). The critical micellar concentration (CMC) of the NLAA-ILs was found to be 2 to 4-fold lower compared with the conventional surfactant sodium dodecyl sulfate (SDS). The thermodynamic behavior confirmed that the micelle formation of NLAA-ILs was stable, spontaneous and entropy driven at room temperature. DLS and TEM studies revealed that the size and shape of the micelles depended on the presence of an N-hydrogen group in the head group of the anion. Choline N-lauroyl glycinate ([Cho][NLG]) and dicholine N-lauroyl aspartate ([Cho](2)[NLA]) were predominantly produced as unilamellar vesicles in water whereas choline N-lauroyl sarcosinate ([Cho][NLS]) formed small spherical micelles. Importantly, SAIL [Cho][NLG] showed lower toxicity toward mammalian cells compared with the analogous Rs or the conventional surfactant SDS and similar toxicity to the conventional surfactant Tween 80. SAIL [Cho][NLG] was more efficient at forming hydrophobic ion pairs with the macromoleadar drug heparin compared with SAIL [Cho][NLS]. These results clearly suggest that the biocompatible NLAA-ILs represent promising potential substitutes for conventional surfactants in various biomedical applications. (C) 2020 Elsevier B.V.

A redox and pH dual-triggered drug delivery platform based on chitosan grafted tubular mesoporous silica

Tubular mesoporous silica (T-mSiO(2)) was facilely synthesized through a co-template method by using cetyltrimethylammonium bromide and alpha-Fe2O3 as the dual templates, and then disulfide (-SS-) bonds and carboxyl groups (-COOH) were introduced to the resultant T-mSiO(2) via the reaction with 2-carboxyethyl 2-pyridyl disulphide. The obtained -SS- grafted T-mSiO(2) (SS-T-mSiO(2)) was then grafted with chitosan (CS) via the amidation reaction between the -COOH groups on SS-T-mSiO(2) and the -NH2 groups on CS. The CS grafted SS-T-mSiO(2) (CSSS-T-mSiO(2)) was fully characterized by various technologies such as transmission electron microscopy, energy dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Finally, the as-synthesized CS-SS-T-mSiO(2) was used as the carrier for redox and pH dual-triggered delivery of 5-fluorouracil (5-FU), an anti-cancer drug, and the results indicate that the developed CS-SS-T-mSiO(2) might be a potential responsive carrier for redox and pH dual-triggered drug delivery.

Drivers of disinfection byproduct formation and speciation in small, chlorinated coastal groundwater systems: relative roles of bromide and organic matter, and the need for improved source water characterization and monitoring

Numerous small public groundwater systems on coastal islands in Washington State (WA) that are susceptible to seawater intrusion have reported disproportionately high frequencies of regulatory exceedances for halogenated organic DBPs; especially brominated DBPs. Fifteen such systems spread across a similar to 1000 km(2) study area were monitored quarterly over a year in a collaboration between the WA Department of Health and University of Washington to identify key drivers of these trends, and to develop operational and regulatory recommendations aimed at minimizing DBP formation in these and similar systems in WA and elsewhere. [Br-] alone was not observed to be a strong predictor of DBP formation potentials (DBP-FPs) or speciation for source waters across the study area, likely due to accompanying large variations in [DOC]. However, bromine substitution factors correlated relatively well with [Br-]/[DOC] ratios, highlighting the importance of both [Br-] and [DOC] in governing DBP formation and speciation in coastal groundwaters. Overall DBP-FPs correlated strongly with [DOC], UV absorbance at 254 nm (A(254)), and selected size exclusion chromatography (SEC) and fluorescence metrics for each groundwater, with A(254) a particularly strong surrogate for DOC. This was consistent with high uniformity of DOM properties (confirmed from SUVA(254), fluorescence index, PARAFAC components, and SEC chromatograms) across the study area. Specific DBP-FPs (e.g., similar to 72 mu g(TTHM) mg(C)(-1)) for the source waters were quite high compared to typical groundwaters, pointing to inherently high DOM reactivity as an additional factor in the frequent DBP regulatory exceedances observed for the investigated sites. Measurements also revealed seasonal trends (e.g., in [Br-] and [DOC]) correlated with DBP formation, but not captured by routine regulatory monitoring, as well as widespread inconsistencies in chlorination practices at the studied systems. While such factors and correlations are well established for surface waters, this work provides one of the few examinations incorporating both laboratory and full-scale observations to demonstrate their importance in small, coastal groundwater systems. Based on these findings, WA has adopted a number of changes in its design manual for new groundwater disinfection systems, and is evaluating changes in its disinfection monitoring and DBP programs that may also serve as models for wider implementation.
