Solid-State EDLC Device Based on Magnesium Ion-Conducting Biopolymer Composite Membrane Electrolytes: Impedance, Circuit Modeling, Dielectric Properties and Electrochemical Characteristics

The polymer electrolyte based on Dx:Cs:Mg(CH3COO)(2):Ni with three different glycerol concentrations have been prepared. The impedance study has verified that the electrolyte with 42 wt.% of glycerol (A3) has the highest ionic conductivity of 7.71 x 10(-6) S cm(-1) at room temperature. The ionic conductivity is found to be influenced by the transport parameters. From the dielectric analysis, it was shown that the electrolytes in this system obeyed the non-Debye behavior. The A3 electrolyte exhibited a dominancy of ions (t(ion) > t(e)) with a breakdown voltage of 2.08 V. The fabricated electrochemical double layer capacitor (EDLC) achieved the specific capacitance values of 24.46 F/g and 39.68 F/g via the cyclic voltammetry (CV) curve and the charge-discharge profile, respectively. The other significant parameters to evaluate the performance of EDLC have been determined, such as internal resistance (186.80 to 202.27 Omega) energy density (4.46 Wh/kg), power density (500.58 to 558.57 W/kg) and efficiency (92.88%).

Pd-KIT-6: synthesis of a novel three-dimensional mesoporous catalyst and studies on its enhanced catalytic applications

Synthesis of a novel three-dimensional mesoporous Pd-KIT-6 is carried out by a room temperature sol-gel method. The synthesised material is well crystalline observed from the Small angle powder X-ray diffraction. Calcination at 550 degrees C for 8 h retains the structure. The particle sizes are in the micron range. Si/Pd ratio of the as-synthesized material is found to be 45 against the input ratio 100. Transmission electron micrograph reveals the presence of the porous hexagonal structure. Thermogravimetric studies reveal that the KIT-6 (Korea Advanced Institute of Science and Technology number 6) undergo less weight-loss compared to Pd-KIT-6, which indicates the material is more crystalline than its metal-free counterpart due to the enhanced crystallisation rate. These results also supported by BET-surface area and Transmission electron microscopic picture. The 960 cm(-1) band at Fourier transform Infrared spectroscopic analysis shows that the incorporation of Pd in the framework. These FT-IR results also supported by Raman Spectroscopic analysis. Electron spin resonance spectroscopic analysis shows that the Palladium is present in the +2 oxidation state in as-synthesized samples. Diffused reflectance Ultraviolet-Visible spectroscopic results show that Palladium is in tetrahedral coordination. Microwave irradiated Suzuki-Miyaura (SM) cross-coupling reactions studied by using the Pd-KIT-6 catalyst in detail without any organic solvent at 100 degrees C for 10 min. The reaction carried out in the presence of phenyl iodide, phenylboronic (PhB(OH)(2)), and K2CO3 produce biphenyl, with 98% yield. Change of halide to Phenyl bromide gave similar results, but Phenyl chloride gave lesser conversion (20%). It is due to the electronegativity difference between the halides. A plausible reaction mechanism is also proposed.

Irreversibility in Anion Exchange Between Cesium Lead Bromide and Iodide Nanocrystals Imaged by Single-Particle Fluorescence

Anion exchange is a powerful method to tune the emission wavelength of perovskite CsPbX3 (X = CI, Br, or I) nanocrystals across the visible spectrum. CsPbX3 nanocrystals can possess a number of crystal structures that depend on both their composition and size. Understanding the role these structural variations play during anion exchange is important for their future application in optoelectronic devices. In this work, we used fluorescence microscopy to monitor reaction trajectories of individual nanocrystals as they undergo anion exchange between CsPbBr3 and CsPbI3. By varying the concentration of substitutional ion used to induce anion exchange, we quantify differences in reaction times for exchange in opposite directions. CsPbI3 nanocrystals undergo more abrupt shifts in their emission characteristics as they transform to CsPbBr3, while CsPbBr3 nanocrystals exhibit a smoother transition during their transformation to CsPbI3. Simulations of anion exchange using Monte Carlo trajectories are consistent with a larger degree of structural reorganization when CsPbI3 nanocrystals undergo anion exchange. Together, these results reveal that there are structural differences between CsPbI3 nanocrystals synthesized by the hot-injection method and those produced by anion exchange. The narrower distribution of reaction times when CsPbI3 nanocrystals transform to CsPbBr3 may produce better compositional homogeneity when this reaction is scaled-up to incorporate these materials into optoelectronic devices.

Comparative Study of the Efficacy of Different Artemisia Cina Extracts and their Nanoparticulated Forms against A549 Lung Cancer Cell Line

The present study aimed to investigate the possible antiproliferative effects of the plant extracts of Artemisia cina on lung cancer, and whether the nanoencapsulation of the plant extracts in the form of nanoemulsion would potentiate their therapeutic efficacy. Soxhlet extraction of the freshly collected shade-dried plant using n-hexane and methanol was performed, and the two extracts were loaded within nanoemulsion using the water dilution method. The nanoemulsion was characterized for its particle size, zeta potential, polydispersity, physicochemical stability under refrigeration conditions, and was morphologically visualized using transmission electron microscopy. The antiproliferative activity of the extracts and their nanoforms was tested in A549 lung cancer cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Results revealed the successful preparation of the plant extract-loaded nanoemulsions with suitable particle size from 15-16 nm, a homogenous dispersion with polydispersity index (PDI) ranging from 0.23-0.31, and neutral surface charge. The nanoemulsions displayed insignificant changes in their physicochemical properties after storage for 3 months, and their spherical morphology was confirmed using transmission electron microscopy. Both n-hexane and methanol extracts di splayed antiproliferative activity against A549 cells, with IC50 values of 35.96 +/- 1.7 and 41.6 +/- 2.8 mu g/ml, respectively. On the other hand, their respective nanoparticulated forms displayed superior antiproliferative activity, with IC50 values of 12.59 +/- 0.7 and 5.6 +/- 0.4 mu g/ml, respectively. Therefore, it can be concluded that nanoencapsulation of plant extracts would significantly potentiate their antiproliferative activity, which paves the way towards a more effective anticancer therapy.

Nitrite sensor based on room temperature ionic liquid functionalized alpha-zirconium phosphate modified glassy carbon electrode

A novel ionic liquid/alpha-ZrP (C16MIM/alpha-ZrP) lamellar nanocomposite was fabricated via the electrostatic self-assembly deposition technique by using exfoliated alpha-ZrP nanosheets and guest molecules (1-hexadecyl-3-methylimidazolium bromide) as building blocks under mild conditions. C16MIM/alpha-ZrP nanocomposite was characterized by various analytical techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), Fourier transform infrared spectroscopy, and synchronous thermal analyzer. The net interlayer spacing of alpha-ZrP determined by XRD confirmed that the C16MIM cations formed a monolayer arrangement between the alpha-ZrP nanosheets. The morphology and microstructure of C16MIM/alpha-ZrP composite were observed using SEM and TEM. The C16MIM/alpha-ZrP modified glass carbon electrode exhibited excellent electrocatalytic activity toward the oxidation of nitrite in weak base media. The results obtained with differential pulse voltammetry demonstrated that the C16MIM/alpha-ZrP hybrid detected nitrite linearly in the concentration range from 7.3 mu M to 1.25 mM with the detection limit of 1.26 mu M (S/N = 3). Additionally, the prepared sensor showed outstanding reproducibility, high stability, and anti-interference capability.

Reversible Release and Fixation of Bromine in Vacancy-Ordered Bromide Perovskites

Bromine is an irreplaceable reagent for many important applications including necessary additive for flame retardants and rubber treatment. However, the toxicity, causticity, and vaporability of bromine make the safe usage and transportation of bromine challenging, which can be alleviated by the bromine prefixation. Herein, vacancy-ordered bromide perovskites such as Cs4Sb2Br12 and Cs2PdBr6 are selected out for the bromine fixation through density-functional theory calculations and experiments. The redox within the bromide perovskites is designed to provide the driving force for the reversible release and fixation of bromine. Heating and cooling the title bromide perovskites in a necked ampoule make the bromine visible and separable from the solid residue. The composition engineering (i.e., Cs4Sb2Br12 vs Rb4Sb2Br12, and Cs4Sb2Br12 vs Cs2PdBr6) can effectively tune the stability (against water and high temperature) and the bromine storage capacity (from 9.30% to 18.76%). In addition, this work can provide a one-step preparation method for the liquid bromine without further purification.

A novel oncolytic adenovirus inhibits hepatocellular carcinoma growth

Objective To evaluate the inhibitory role of a novel oncolytic adenovirus (OA), GP73-SphK1sR-Ad5, on the growth of hepatocellular carcinoma (HCC). Methods GP73-SphK1sR-Ad5 was constructed by integrating Golgi protein 73 (GP73) promoter and sphingosine kinase 1 (SphK1)-short hairpin RNA (shRNA) into adenovirus serotype 5 (Ad5), and transfecting into HCC Huh7 cells and normal human liver HL-7702 cells. The expression of SphK1 and adenovirus early region 1 (E1A) was detected by quantitative real-time PCR (qRT-PCR) and western blot, respectively. Cell viability was detected by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay, and apoptotic rate was determined by flow cytometry. An Huh7 xenograft model was established in mice injected intratumorally with GP73-SphK1sR-Ad5. Twenty days after injection, the tumor volume and weight, and the survival time of the mice were recorded. The histopathological changes in tumor tissues were observed by hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM). Results Transfection of GP73-SphK1sR-Ad5 significantly upregulated E1A and downregulated SphK1 in Huh7 cells, but not in HL7702 cells. GP73-SphK1sR-Ad5 transfection significantly decreased the viability and increased the apoptotic rate of Huh7 cells, but had no effect on HL7702 cells. Intratumoral injection of GP73-SphK1sR-Ad5 into the Huh7 xenograft mouse model significantly decreased tumor volume and weight, and prolonged survival time. It also significantly decreased the tumor infiltration area and blood vessel density, and increased the percentages of cells with nucleus deformation and cells with condensed chromatin in tumor tissues. Conclusions GP73-SphK1sR-Ad5 serves as a novel OA and can inhibit HCC progression with high specificity and efficacy.

The device was first converted to blue color from transparent when 1.0 V was applied, and then neutral gray color when the potential bias was increased to 2.0 V. Meanwhile, the corresponding optical contrasts (Delta T) were 54.5% and 22% at 392 nm and 605 nm, respectively. In addition, a good coloration efficiency of 128.9 cm(2) C-1 at 2.0 V and fast switching time (<2.5 s) were obtained. Finally, satisfied stability with 43.8% of Delta T (maintaining 80% of initial Delta T at 392 nm) was achieved after 2000 cyclic processes, which paves a new way to design colorless to neutral color ECDs.

Cytoproliferative and Anti-Oxidant Effects Induced by Tannic Acid in Human Embryonic Kidney (Hek-293) Cells

Tannic acid (TA) portrays a myriad of beneficial properties and has forthwith achieved incessant significance for its cytoprotective qualities in traditional and modern-day medicine. However, TA displays an ambiguous nature demonstrating anti-oxidant and pro-oxidant traits, beckoning further research. Although vast literature on the anti-proliferative effects of TA on cancer cell lines exist, the effects on normal cells remain unchartered. Herein, the cytoproliferative and anti-oxidant effects induced by TA in human embryonic kidney (Hek-293) cells were investigated. Data obtained from the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay demonstrated that TA increased the cell viability and cellular proliferation rate at higher concentrations. Hoechst assay, examining proliferation marker Ki67 supported these findings. DNA fragmentation and oxidative stress-inducers were specifically noted at IC25 and IC50 treatments via biochemical assays. This alluded to TA’s pro-oxidant characteristics. However, the countervailing anti-oxidant defence mechanisms as the endogenous anti-oxidants and phase2 detoxification enzymes were significantly upregulated. Luminometry fortified the anti-oxidant capacity of TA, whereby executioner caspase-3/7 were not activated subservient to the activation of initiator caspases-8 and -9. Thus, proving that TA has anti-apoptotic traits, inter alia. Therefore, TA proved to harbour anti-oxidant, anti-apoptotic, and proliferative effects in Hek-293 cells with its partial cytotoxic responses being outweighed by its cytoprotective mechanisms.
