    Abstract Rechargeable aqueous zinc-ion batteries are considered as promising candidates for safe and green energy storage. Yet, Zn anodes still suffer from serious challenges. Herein, an effective cation-sieve of polyethersulfone-modified sulfonated polyether ether ketone is developed as protective coating layer of the Zn anodes. Cation-only transmission and dense property of the layer can protect the Zn from active water and anions, inhibiting corrosion, hydrogen evolution reaction (HER), and passivation. Zincophilic property of the layer can homogenize Zn

    Abstract Alkaline nickel-zinc (Ni-Zn) batteries, as traditional rechargeable aqueous batteries, possess an obvious advantage in terms of energy density, but their development has been hindered by the anode-concerned problems, Zn dendrites, self-corrosion, passivation, deformation, and hydrogen evolution reaction (HER). Herein, to solve these problems, a dual protective strategy is proposed toward the anode using ZnO as an initial active material, including a C coating on ZnO (ZnO@C) and a thin poly­(vinyl alcohol) (PVA) layer coating on the electrode (ZnO@C-PVA). In a three-electrode configuration, the reversible capacity can reach 600 mAh g-¹ for the ZnO@C-PVA. Using excessive commercial Ni­(OH)₂ as the cathode, the alkaline Ni-Zn cells exhibit good electrochemical performance: Discharge capacity can be as high as 640-650 mAh g-¹ at 4 A g-¹ with a Coulomb efficiency (CE) as high as 97-99% after activity, suggesting low self-corrosion and HER. Capacity retention is 97% after 1200 cycles, indicating rather good durability. The discharge capacity is even slightly increased with the increase of charge/discharge current density (≤8 A g-¹), implying good rate performance. Additionally, the discharge voltage can reach 1.8 V (midpoint value) at various current densities, reflecting the fast reaction kinetics of the anode. Most importantly, no Zn dendrites and passivation are observed after long-term cycling. The strategy proposed here can solve the anode-concerned problems effectively, exhibiting a high application prospect.

    Abstract Elderly individuals with non-dipper hypertension are at high risk of cardiovascular disease because of increased stiffness of peripheral arteries. Since, vitamin D deficiency is prevalent in elderly Chinese. We examined whether reduced plasma levels of 25-hydroxyvitamin D [25(OH)D] may help promote this stiffness.Hypertensive patients at least 60 years old without history of peripheral arterial disease at our hospital were retrospectively divided into dipper and non-dipper groups according to the results of 24-hour ambulatory blood pressure monitoring. Plasma levels of 25(OH)D were measured by enzyme immunoassay. Peripheral arterial stiffness was measured based on the cardio-ankle vascular index (CAVI).Of the 155 patients enrolled, 95 (61.3%) were diagnosed with non-dipper hypertension and these patients had significantly lower plasma levels of 25(OH)D than the 60 patients with dipper hypertension (19.58 ± 5.97 vs 24.36 ± 6.95 nmol/L, P < .01) as well as significantly higher CAVI (8.46 ± 1.65 vs 7.56 ± 1.08 m/s, P < .01). Vitamin D deficiency was significantly more common among non-dipper patients (57.9% vs 31.7%, P < .01). Multivariate regression showed that age and 25(OH)D were independently related to CAVI, with each 1-ng/ml decrease in 25(OH)D associated with a CAVI increase of +0.04 m/s.Non-dipper hypertension is associated with vitamin D deficiency and reduced plasma levels of 25(OH)D. The latter may contribute to stiffening of peripheral arteries, increasing the risk of cardiovascular disease.

    Abstract Determination of phytate and phosphate by suppressed conductivity ion chromatography was investigated. Plant samples were extracted with 1% (mass fraction) trichloroacetic acid (TCA). After centrifugal settling, the supernatant was filtered with a 0.45 microm filter membrane before injected into the ion chromatographic system and detected by suppressed conductivity. The gradient eluent was composed of 0.22 mol/L sodium hydroxide solution, water and 50% (v/v) isopropyl alcohol solution. Phytate and phosphate were determined within 15 min, and no interference was found in the presence of fluorate, chlorate, nitrate, sulphate and TCA. Good linearities for phytate and phosphate were obtained in the ranges of 5-400 mg/L (r2 = 0.9994) and 5-500 mg/L (r2 = 0.9999), and the detection limits (S/N = 3) were 3.5 mg/L and 1.5 mg/L, respectively. The average recoveries for phytate and phosphate were 99.8% and 98.4%, and their relative standard deviations were 1.98% and 2.09%, respectively.

    Abstract Gold nanoparticles were in-situ decorated on top of a polyaniline film (GNPs-PANI) via the direct electroreduction of the adsorbed AuCl ₄ ⁻ ions on a glassy carbon electrode that previously was coated with PANI by electropolymerization. The GNPs-PANI composite and the performance of the resultant sensors were investigated in some detail. The sensor was applied to the oxidation of dopamine (DA) with improved catalytic activity. Its catalytic current showed wide linear response toward dopamine ranging from 3 to 115 μM, with a low detection limit of 0.8 μM (S/N=3). In addition, the sensor exhibits easy-operation, fast response to dopamine, as well as excellent reproducibility and stability. [graphic removed]

    Abstract Spermine-graft-dextran (Spe-g-Dex) copolymer was synthesized and used as a non-covalent coating for the separation of proteins and neurotransmitters by capillary electrophoresis. The coating was obtained via flushing the capillary with 1.0% Spe-g-Dex copolymer solution for 2min. Electroosmotic flow (EOF) was strongly suppressed, ranging from −1.60×10⁻⁹ to 3.65×10⁻⁹ m² V⁻¹ s⁻¹. Effect of experimental conditions, such as the copolymer concentration, the concentration and pH of the background electrolyte (BGE), on the Spe-g-Dex coating was investigated. Separation of lysozyme, cytochrome c, ribonuclease A and α-chymotrypsinogen yielded high separation efficiencies ranging from 141000 to 303000plates/m and recoveries from 85.4% to 98.3% at pH 4.0 (284.0mM sodium acetate-acetic acid buffer, I =50mM). Run-to-run repeatabilities and day-to-day, and capillary-to-capillary reproducibilities were all below 1.7%. In addition, Spe-g-Dex coating allowed the successful separation of five neurotransmitters, 5-hydroxytryptamine, dopamine, epinephrine, isoprenaline, dobuamine at pH 4.0 with high separation efficiencies of 290000-449000plates/m.
