A transparent-to-gray electrochromic device based on an asymmetric viologen

A transparent-to-gray electrochromic device (ECD) based on an asymmetric viologen was fabricated and characterized. The core material derived from novel bipyridine salt (named 1-(2-(diethoxy-phosphoryl)ethyl)-1 ‘-(4-vinylbenzyl)-[4,4 ‘-bipyridine]-1,1 ‘-diium chloride bromide, DVB) combined with complementary species of ferrocene was assembled in a device with a simple configuration of ITO/EC solution/ITO. 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.

The Interaction of Glymes with Surfactant Micelles

The critical micelle concentrations (CMC) values and counterion dissociation (alpha values) have been determined for a number of mixed micellar systems consisting of two typical ionic surfactants and glycol ethers (glymes) as cosurfactants, namely diethylene glycol dimethyl ether, diethylene glycol diethyl ether, triethylene glycol dimethyl ether, and tetraethylene glycol dimethyl ether. Conductance experiments were used to determine the CMC and alpha values of the mixed micelles as a function of glyme concentration in the aqueous mixed solvent. Favorable interactions between sodium dodecyl sulfate micelles and glyme cosurfactants were deduced from the decreases in the CMC values and the large increase in the alpha values of these systems as a function of increasing glyme concentration in the mixed solvents. In contrast to the anionic surfactant/glyme systems, in general, there appeared to be little favorable interactions between the surfactant and glymes when micelles of the cationic surfactant dodecyltrimethylammonium bromide were formed in water/glyme solvent systems containing an increasing amount of the glymes. The interaction of glymes with the surfactant micelles was examined closely via C-13 nuclear magnetic resonance (NMR) chemical shifts for both surfactant and glyme carbons; these chemical shifts changes were interpreted in terms of the distribution and the localization of the glymes in the aggregates. Finally, partition constants, determined from two-dimensional diffusion-oriented spectroscopy (2D-DOSY) experiments, were used to calculate thermodynamic quantities of transfer of the glymes between the bulk phase and the self-assembled aggregates. All these results are interpreted in terms of the key contributions that both the glyme ethoxylated groups and alkyl endgroups make to the hydrophobic interactions.

Solid-liquid equilibria for the ternary systems of RbX + CdX2 + H2O (X = Cl, Br) at T=298.15 K and the thermodynamic properties of the new solid compounds

Solid-liquid equilibria in the ternary systems RbX + CdX2 + H2O (X = Cl, Br) at T = 298.15 K and under 101.3 kPa were investigated by the method of isothermal solution saturation, and the corresponding phase diagrams were constructed. It was found that there were five crystallization regions corresponding to CdCl2 center dot 2.5H(2)O, RbCd(2)Cl5 center dot H2O, RbCdCl3, Rb4CdCl6 and RbCl in the system (RbCl + CdCl2 + H2O). Four crystallization regions corresponding to CdBr2 center dot 4H(2)O, RbCdBr3, Rb4CdBr6 and RbBr were found in the system (RbBr + CdBr2 + H2O). The new solid compounds RbCdCl3, RbCdBr3 and Rb4CdBr6 were congruently soluble in water, and new double salts RbCd2Cl5 center dot H2O and Rb4CdCl6 were incongruently soluble in water. The new solid-phase compounds RbCd2Cl5 center dot H2O, RbCdCl3, Rb4CdCl6, RbCdBr3 and Rb4CdBr6 were characterized by chemical analysis, XRD and TG-DTG techniques.

A dual promotion strategy of interface modification and ion doping for efficient and stable carbon-based planar CsPbBr3 perovskite solar cells

Carbon-based all-inorganic cesium lead bromide (CsPbBr3) halide perovskite solar cells (PSCs) have attracted tremendous attention owing to their low cost, simplified preparation, and outstanding stability even under harsh conditions. However, the CsPbBr3 perovskite always suffers from an undesirable crystallization and film morphology with incomplete coverage and numerous grain boundaries. Herein, a novel dual promotion strategy combining interface modification with ion doping is proposed to achieve highly efficient and stable carbon-based planar CsPbBr3 PSCs. A thin CsBr modified layer was first inserted between the compact TiO2 (c-TiO2) and PbBr2 layers, wherein the crystallization of PbBr2 can be enhanced and then assist the growth of perovskite grains can be provided, so that CsPbBr3 films can reduce pinhole generation and accelerate carrier extraction, and decrease the hysteresis effect. Then an appropriate cobalt (Co2+) ion is doped into the CsPbBr3 film, which not only increases the grain size with decreasing grain boundary, but also ameliorates the energy level and recombination. Consequently, the champion power conversion efficiency (PCE) of the CsPbBr3 PSCs reaches up to 8.67% with an increment of about 30%. Moreover, the best-performing PSC without encapsulation also displays excellent humidity and thermal stability, maintaining above 98% of its initial PCE in an air atmosphere after 100 days, and over 95% under heat treatment at 85 degrees C after 600 hours, respectively. This study provides a promising route to boost the performance of all-inorganic perovskite solar cells.

Surface active monomers: from micellar solution properties to molecular characteristics

Hydrodynamic methods and light scattering were used in the studies of solutions of a surface active monomer 11-acryloyloxyundecyltrimethylammonium bromide (AUTA-Br) and its polymers in 0.05 M NaCl. Aqueous solutions of AUTA-Br monomer in the concentration range of 4 to 16 CMC contain individual molecules and near-spherical AUTA-Br aggregates. The pAUTA-Br polymers possess rather high equilibrium rigidity (11.8 nm). This high value of equilibrium rigidity found for pAUTA-Br macromolecules is apparently caused by two factors: the presence of a bulky side substituent in each AUTA-Br monomer unit and incomplete suppression of electrostatic interactions between neighboring monomer units in the backbone.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 3972-65-4, you can contact me at any time and look forward to more communication. COA of Formula: C10H13Br.

The role of S100B and nitric oxide in the apoptotic action of pentylenetetrazole on astrocytes

Introduction: Astrocyte, S100B and nitric oxide may have a role in the pathogenesis and treatment of epilepsy. However, the effects of nitric oxide and S100B on the gliotoxic effects of chemical convulsants such as pentylenetetrazole (PTZ) is unknown. Therefore, we aimed to evaluate the effects of S100B and nitric oxide on gliotoxicity of PTZ in a 1321NI1 astrocytic culture. Methods: The 1321N1 astrocytes were exposed to PTZ (40mM), arundic acid (50 mu M) or both of them for 24h. In addition, we poured L-arginine (100 or 500 mu M), N-nitro-L-arginine methyl ester (100 or 500 mu M), 7-nitroindazole (30 or 100 mu M) and aminoguanidine (50 or 100 mu M) to the culture media contained PTZ, arundic acid or both of them and incubated for 24h. Cell viability was measured by the methylthiazolyldiphenyl-tetrazolium bromide reagent and the S100B protein level was measured using an enzyme-linked immunosorbent assay. Results: There was a negative correlation between cell viability in astrocytes and the intracellular S100B levels. PTZ decreased cell viability, but it increased the intracellular S100B levels. Arundic acid, N-nitroarginine methyl ester, 7-nitroindazole and aminoguanidine reversed the PTZ effects on cell viability and intracellular S100B levels. Adding the L-arginine to PTZ plus arundic acid reduced the modulatory effects of arundic acid on PTZ. Conclusion: Nitric oxide and S100B have a role in gliotoxicity of PTZ in cell culture. Arundic acid suppresses PTZ-induced S100B elevation and gliotoxicity possibly by modulation of the nitric oxide pathway.

One-dimensional polymeric iodoplumbate hybrids with lanthanide complex cations: syntheses, crystal structures, and photoelectric and photocatalytic properties

New iodoplumbate hybrids with lanthanide complexes [La(DMF)(8)]Pb3I9 (1) and [Ln(DMF)(8)]Pb5I13 (Ln = Sm (2), Gd (3)) (DMF = N,N-dimethylformamide) were prepared using octakis complex cations [Ln(DMF)(8)](3+) formed in situ as structure directing agents by volatilizing at room temperature. The polymeric 1-D [Pb3I9](n)(3n-) anion in compound 1 is constructed by PbI6 octahedral units via face-sharing featuring a waved chain structure, while the 1-D [Pb5I13](n)(3n-) anion in 2 and 3 is composed of PbI6 units via both edge-sharing and face-sharing. The compounds 1-3 show steep band gaps at 3.02, 2.61, and 2.57 eV, respectively, indicating potential semiconducting properties. They exhibit catalytic activities in the photodegradation of organic pollutants like crystal violet (CV) and methylene blue (MB). Compounds 2 and 3 are more effective than 1 in the photocatalytic degradation of CV, which are related to their intensity of the photocurrent response. The photocurrent response, cyclic voltammetry measurements and photocatalytic mechanism investigation for compound 2 show that OH radical and h(+) hole are the main reactive species in the degradation experiment of CV.
