The electrochemical urea oxidation reaction (UOR) is the performance‐limiting half of electrolysis for producing renewable hydrogen energy. Nevertheless, essence electrode function mechanism catalysts remains unclear. Therefore, design and optimization are restricted. Herein, an in situ Raman spectroscopy method employed to directly measure properties NiCo double hydroxides (NiCo DHs) under working conditions. Given definitely evidence, evolution process spectra shows that Ni element...
An ammonia electrolytic cell with NiCu/C as anode catalyst for hydrogen production is presented. The electrochemical oxidation of was investigated on prepared by a chemical reduction method. It found that current response strongly dependent the mass ratio Ni and Cu. Cyclic voltammetry polarization curves showed 50 wt. % Ni50Cu50/C electrode energy-effective. electrolyzer can operate under low voltage to save energy in production.
Herein, we present the facial preparation of one-dimensional nanoscale square rod array Sn–Co–Cu alloy films through electrodeposition and subsequent annealing methods under template-free condition, their electrochemical performances assembled lithium cells as anode were tested in detail. The results indicated that anodes displayed an excellent cyclic performance. discharge capacities 1072 897 mA h g–1 at corresponding current densities 200 2000 after 500 cycles, with a high capacity...
Lithium-sulphur (Li-S) batteries are high-energy-density and cost-effective batteries. Herein, petal-like Ni1-x Mn x (OH)2 (x ≈ 0.04) nanosheets were synthesised using a hydrothermal method the electrical conductivity of Ni(OH)2 was improved by applying cathode functional materials in Li-S With up to 5 mg cm-2 S content cathode, fabricated electrode exhibited specific discharge capacities 1375 1150 mA h g-1 at 0.2 0.5C, retained this capacity 813 714 after 200 cycles, respectively....
Summary The Fourier-series method (FSM) is used to solve the prediction problems of sucker-rod pumping systems. With displacement and load at any point rod string, by means FSM, other string are obtained. no need pump models, FSM easily predicts various conditions that challenges conventional methods. As for prediction, valuable design, selection, installation, operation diagnostics, surface cards generated can be as characteristic diagnosis systems in situations when only available. also a...
Stabilizing LiCoO2 (LCO) at 4.5 V rather than the common 4.2 is important for high specific capacity. In this study, we developed a simple and efficient way to improve stability of voltages. After sol–gel method, introduced trifluoroacetic acid (TA) surface LCO via an afterwards calcination. Meanwhile, TA reacted with residual lithium on LCO, further leading formation uniform LiF nanoshells. The nanoshells could effectively restrict interfacial side reaction, hinder transition metal...
An effective myoglobin-Nafion film is prepared by introducing gold nanoparticles in through a simple procedure ion-exchange combined with electrochemical reduction. Gold are highly dispersed an average size of 2.3 +/- 0.2 nm. The behavior myoglobin entrapped the has been carefully investigated cyclic voltammetry. results show that introduction into makes direct electron transfer efficient. A pair well-defined redox peaks for heme Fe(II)/Fe(III) observed formal potential -0.150 V 0.1 M...
Euler spirals are a kind of fair curves that have linear curvatures in terms arc length. However, cannot be represented by polynomials exactly. In this paper, we propose an algorithm for approximating segment spiral which interpolates two specified points and tangents at the B-spline curve. The curve is obtained as solution to differential equation satisfies boundary conditions. Similar exact interpolating spiral, also has approximate curvature. Furthermore, fitting data sequence smoothly...
We propose to use Galilee invariance in hydrodynamics and Lorentz of relativistic order simplify the upwinding numerical scheme.
Octane number is an important indicator reflecting the combustion performance of gasoline. To accomplish octane modeling and its control variables optimization effectively, this paper proposes a novel method MDR-NSGA-II which combines multi-level dimension reduction (MDR) non-dominated sorting genetic algorithm II (NSGA-II). Firstly, based on chemical data, MDR used to select obtain main variables. The integrates advantages distance correlation coefficient, sparse representation method,...
