Biphenyl-lithium-TEGDME solution as anolyte for high energy density non-aqueous redox flow lithium battery

Non-aqueous redox flow batteries, because of larger operating voltage, have attracted considerable attention for high-density energy storage applications. However, the study of the anolyte is rather limited compared with the catholyte due to the labile properties of redox mediators at low potentials. Here, we report a new strategy that exploits high concentration organic lithium metal solution as a robust and energetic anolyte. The solution formed by dissolving metallic lithium with biphenyl (BP) in tetraethylene glycol dimethyl ether (TEGDME) presents a redox potential of 0.39 V versus Li/Li+, and a concentration up to 2 M. When coupled with a redox-targeted LiFePO4 catholyte system, the constructed redox flow lithium battery full cell delivers a cell voltage of 3.0 V and presents reasonably good cycling performance.

Colorimetric Aptasensor Based on Truncated Aptamer and Trivalent DNAzyme for Vibrio parahemolyticus Determination

In this work, after optimizing the original aptamer sequence by truncation and site-directed mutagenesis, a simple and sensitive colorimetric aptasensor was established for detecting the widespread food-borne pathogen Vibrio parahemolyticus (V. parahemolyticus). The detection strategy was based on the competition for an V. parahemolyticus specific aptamer between its complementary DNA (cDNA) and V. parahemolyticus. The aptamer-conjugated magnetic nanoparticles (MNPs) were used as capture probes, and the G-quadruplex (G4) DNAzyme was employed as the signal amplifying element. Under optimal conditions, a wide linear detection range (from 102 to 107 cfu/mL) was available, and the detection limit could be as low as 10 cfu/mL. This method was also used to detect V. parahemolyticus in contaminated salmon samples, and the results showed good consistency with those obtained from standard plate counting method. Therefore, this novel aptasensor could be a good candidate for sensitive and selective detection of V. parahemolyticus without complicated operations.

The reaction of ferrocene-1,1′-dicarbaldehyde with 2-acetylpyridine at room temperature for 24 h results in the synthesis of 3,5-[1,1′-ferrocenediyl]-1,7-di(2-pyridylcarbonyl)heptane instead of the expected enone or 1,5-dicarbonyl. The crystal structure of this compound has been determined by single-crystal X-ray methods. The complex is electroactive and exhibits a reversible iron(II)/(III) process at +0.014 V vs ferrocene.

Heme oxygenase byproducts variably influences myocardial and autonomic dysfunctions induced by the cyclosporine/diclofenac regimen in female rats

We recently reported that exposure to cyclosporine (CSA) plus diclofenac causes hypertension and impairs left ventricular (LV) and cardiac autonomic functions in female rats. Here, we tested the hypothesis that these effects could be mitigated by facilitated heme oxygenase (HO) signaling. Experiments were performed in female rats to assess the effects of 10-day treatment with CSA (25 mg/kg/day)/diclofenac (1 mg/kg/day) regimen on cardiovascular functions in absence and presence of maneuvers that upregulate HO or its enzymatic products. The CSA/diclofenac-induced hypertension and impairment in cardiac sympathovagal balance (i.e. reduced low-frequency/high-frequency spectral ratio) were blunted upon concurrent treatment with hemin (HO-1 inducer), tricarbonyldichlororuthenium (II) dimer (CORM-2, carbon monoxide-releasing molecule), or bilirubin. While none of the latter treatments affected the CSA/diclofenac-evoked decrease in isovolumic relaxation constant (Tau, a measure of diastolic function), the increased LV contractility (dP/dtmax) and attenuated reflex bradycardia in CSA/diclofenac-treated rats was abolished by bilirubin only. Paradoxically, the CSA/diclofenac-evoked attenuation in reflex tachycardia was improved in presence of hemin or CORM-2, but not bilirubin. The favorable hemin effects were abrogated after inhibition of HO (ZnPP) or nitric oxide synthase (NOS, L-NAME). These finding highlights NOS-dependent modulatory roles for HO and its enzymatic products in improving the worsened cardiovascular profile in CSA/diclofenac-treated female rats.

Highly sensitive conductometric biosensors for total lactate, D- and L-lactate determination in dairy products

An original method combining two conductometric biosensors is proposed for the determination of total lactate, L- and D-lactate in dairy products. The biosensors were prepared through cross-linking of L-lactate oxidase from Pediococcus sp. (LODP) or a combination of LODP and horseradish peroxidase (HRP) at the surface of gold interdigitated microelectrodes using glutaraldehyde (GA) vapors. LODP is reported to catalyze specifically L-lactate oxidation into pyruvate and hydrogen peroxide in solution. In this work, we showed that LODP chiral selectivity was lost following enzyme cross-linking, rendering LODP sensor suitable for total lactate determination. Biosensor sensitivity towards both stereoisomers was 1.16 ¡À 0.04 muS muM-1. The addition of HRP significantly improved the linear range and stability of LODP biosensor, but also increased its sensitivity, the effect being more pronounced for D-lactate (+381%) than for L-lactate (+260%). This result was attributed to a modification in LODP chiral selectivity combined with the production of additional ions (acetate, H+ and HCO3-) via the HRP-catalyzed oxidation of pyruvate. A method, taking advantage of the difference in D- and L-lactate behaviours and combining the monoenzymatic and bienzymatic biosensors calibration data, was proposed for the calculation of their concentrations in unknown samples. Different parameters (HRP/LODP ratio, exposure time to GA vapors, pH and concentration of measurement medium) were optimized in order to achieve the best compromise between sensitivity and stability of the biosensors. The best limit of detection for L- and D-lactate, calculated as three times the signal to noise ratio was achieved with the bi-enzymatic sensor and was equal to 0.05 muM. LODP/HRP biosensor response towards L-lactate was not significantly affected by glucose, fructose and lactose. The proposed biosensors were finally applied to the determination of total lactate, D- and L-lactate concentrations in yogurt samples. Results were in good agreement with those obtained using a reference colorimetric enzymatic method.

Amino acid and peptide hemin derivatives as new promising virucidal agents

We synthesized a series of hemin derivatives (HDs) substituted by residues of amino acids and peptides at either one or two propionic-acid residues, and studied the virucidal activity of the compounds obtained against herpes simplex virus. Compounds 6,7-bis-(methyl ester N0 L-seryl)-protohemin (IX) (2) and 6,7-bis-[methyl ester N0-L-arginyl)-protohemin (IX) (6) shown the highest virucidal activity. We also investigated the interaction between HDs and lipid-membrane components as a possible mechanism of virucidal action. A model system including Clark’s electrode and a micellar solution of methyl linoleate was used to quantitatively assess the capability of HDs to catalyze the oxidation of polyunsaturated fatty acids as components of lipid membranes. Another model system including liposomes that consisted of dioleoylphosphatydylcholine and was loaded with the fluorescent dye carboxyfluorescein was employed to examine the effect of HDs on lipid-membrane permeability. The kinetics and efficacy of increasing liposome-membrane permeability on exposure to HDs appeared to depend on the nature of the substituents in the HDs. The findings are strongly suggestive of the presence of two different modes of interaction between an HD and the lipid membrane, i.e. oxidative and non-oxidative mechanisms possibly underlie the virucidal action of HDs.

An investigation of homogeneous electrocatalytic mechanism between ferrocene derivatives and L-cysteine/N-Acetyl-L-cysteine

The homogeneous electrocatalytic mechanism with a fast catalytic chemical reaction between a series of ferrocene derivatives and L-cysteine/N-Acetyl-L-cysteine (NAC) is systematically investigated. A comparison of different cyclic voltammetric waveforms is given to illustrate the interaction between kinetic parameter (lambda) and excess factor (gamma) in kinetic zone diagram via changing the scan rates and substrate/mediator ratio on both glassy carbon (GC) and boron doped diamond (BDD) working electrode experimentally. A split wave phenomenon is observed between ferroceneacetic acid (FAA) and L-cysteine. Also, the waveforms revealed that electron withdrawing groups (EWG) on the substrate hinders the kinetics of the homogeneous electron transfer while those on the mediator facilitates the same process. The homogeneous electrocatalytic order of the studied mediator is as follows: 1,1?-ferrocenedicarboxylic acid (FDA) > FAA > hydroxymethylferrocene (HMF) > 1-hydroxyethylferrocene (HEF) and the corresponding density functional theory (DFT) calculation is applied to support this statement. Furthermore, the second-order rate constant between FAA and L-cysteine is given by the support of numerical simulation (175 (mol m?3)?1 s?1). The present study would facilitate the understanding of homogeneous electrocatalytic process, especially those possessing a fast catalytic chemical step.

Substituent effects in the iron 2p and carbon 1s edge Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of ferrocene compounds

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.
