Fuel cells are a way of converting fuels into electricity. A notable use of fuel cells is in space vehicles such as the Apollo spacecraft and the space shuttles. There are many types of fuel cells, but they all consist of an anode, a cathode, and an electrolyte that allows charges to...
X-ray photoelectron spectroscopy (XPS; Thermo Fisher Scientific Alpha XPS system, Thermo Fisher Scientific, Cambridge, UK) was used to analyze the binding energies of the elements. Calibration was conducted using the C 1s method, in which the binding energy of C 1s was calibrated at 284.6 eV....
The heat generated in Li-ion batteries is mainly composed of four elements: reaction heat, Joule heat, polarization internal resistance heat, and side-reaction heat. When the exothermic rate of the Li-ion battery exceeds the rate of heat dissipation, the internal temperature of the battery will...
For the phase change problem of layered oxides, the introduction of manganese, iron, copper and other elements doping is often used to obtain a stable crystal structure.Mu et al. used Na2CO3, CuO, Fe2O3, and Mn2O3 to prepare a cobalt- and nickel-free layered metal oxide O3-Na0.9[Cu...
Elements tend to react to acquire the stable electron structure of a noble gas. 元素倾向于通过反应获得如稀有气体般稳定的电子结构。 Positive Ion Formation 正电离子的形成 A positive ion forms when an atom loses one or more valence electrons in order to attain a noble gas configuration. A positiv...
36. We used the separate solution method to calibrate the elements of the ISFET sensor array and extract the Nikolskii selectivity coefficients of each sensor element to each ionic species in our study. With all sensor elements simultaneously measuring the same analyte solution, we used Nikolskii...
G. S. Ofelt Aug 1962 Magnetic and electric dipole transitions between levels of the 4fx configuration perturbed by a static crystalline field are treated. The expression obtained for the pure‐electronic electric‐dipole transition probability involves matrix elements of an even‐order unit tensor betw...
This synergistic combination of elements of copper (Cu), manganese (Mn), and zinc (Zn) with GO to form CZMOG electrode enhances the latter's performance, stability, and life span. Our results show that the synthesized nanocomposites are crystalline with spherical flake-like shapes. The ...
