Abstract:

ZnO nanorods were fabricated by a template-free gel pyrrolysis method based on polyvinyl alcohol (PVA) polymeric network. In the present method, zinc salt precursor is trapped in the homogenized gel network to control the mechanism and kinetics of zinc salt calcinations process. By controlling the gel structure and gel pyrrolysis rate, zinc salt precursor can be calcinated to zinc oxide nanorods. The morphology and particle size of the synthesized sample depend on some parameters including amount of zinc salt and PVA in the initial solution, type and composition of the solvent, type and amount

Abstract:

When fine-sized 45ZnO·55P2O5 or 50ZnO·50P2O5 glass powders were mixed with distilled water, hydration immediately occurred, resulting in the formation of viscous hydrogels. 31P MAS-NMR spectra showed that the hydrogels contain orthophosphates and long-chain phosphates; no significant differences in their structures between the hydrogels were shown. The 45ZP gel and 50ZP gel showed high conductivities (e.g., 9.9 and 2.8 mS/cm, respectively, at 30°C). The conductivities were related to the proton amount in the hydrogel; the amount in the 45ZP gel was larger than that in the 50ZP gel. Electric do

A sago-based gel polymer electrolyte (GPE) was prepared by mixing native sago with potassium hydroxide (KOH) aqueous in order to investigate the applicability of GPE to zinc-air (Zn-air) battery. The viscosity and conductivity of the sago GPE were evaluated using varying sago amounts and KOH concentrations. The viscosity of the sago GPE was kept as a reserve in the region of ~ 0.2 Pa s as the KOH concentration was increased from 2 to 8 M. Sago GPE was found to have an excellent ionic conductivity of (4.45  0.1) x 10-1 S cm-1 with 6 M KOH. GPE was also employed in an experimental Znair battery

Abstract:

Aqueous Zn-ion batteries (AZIBs) are quite promising energy sources. However, aqueous electrolytes present many challenges such as hydrolysis reactions, liquid leakage, Zn dendrites, and interfacial side reactions. To solve the above problems of aqueous electrolytes, in this study, a kind of SiO2-sodium alginate gel polymer electrolyte (SiO2-SA GPE) is prepared through a one-pot method. The SiO2-SA GPE possessed high ionic conductivity of 1.144 × 10−2 S·cm−1 and perfect mechanical strength. The Zn//LiFePO4 batteries assembled with SiO2-SA GPE delivered a high discharge specific capacity of 89.

To test this hypothesis, an experiment was conducted to determine the ultimate tissue distribution of Zinc in rats fed either a radioactively-labeled 65Zn-chelate or 65ZnSO4. The 65Zn-chelate was prepared by heating a solution of 65ZnSO4 and an equimolar mixture of glycine and methionine for 5 minutes at 90°C. The resulting chelate was then separated from unincorporated 65ZnSO4 by gel filtration chromatography

Abstract:

Objective: An efficient and facile preparation route has been developed to prepare activated carbon (AC)/zinc oxide (ZnO) nanocomposite electrodes for the supercapacitor electrode. Methods: The zinc oxide nanostructure was synthesized via the sol-gel method by using conventional hexamethylenetetramine (HMTA) reagent as the reducing agent. Results: The physicochemical and electrochemical properties of the nanocomposites were characterized by X-ray diffraction analysis (XRD) and cyclic voltammetry (CV) analysis, respectively. 10 wt% of ZnO loading shows an optimum specific capacitance of 398 F/g

Thermodynamic calculations indicate that the tendency of dehydration of silica gel is significantly enhanced with the increasing temperature. It was shown that the temperature, ammonium chloride concentration, or L/S ratio increased resulted in greater leaching efficiency. The following optimized leaching conditions were obtained: stirrer speed 400r/min, NH4Cl concentration 5.5M, L/S ratio 9mL/g at 160?C for 3h. Under these opti
