Write the noble gas electron configuration for the Cr2+ ion. Write electron configurations for the following ions, and determine which have noble-gas configurations: a. Cd^2+, b. P^3-, c. Zr^4+, d. Ru^3+, e. As^3-, f. Ag...
元素周期表最右一列的元素被称为 noble gas(稀有气体,又名惰性气体),不过这个名字在历史上被更改过很多次,而且有的元素一点也不稀有,并且也不是惰性的。 从1868年,人们从太阳光谱中发现 He 开始,历经30多年,于1900年终于找到了最后一个放射性...
No Zn-N1C3, Zn-N2C2, Zn-N3C1, Zn-N3 and Zn-N4 configuration-related location site for Zn single atoms was observed. At the meantime, the nitrogenated carbon matrixes are very small in size, which can provide abundant edge sites for the maximum coordinating of Zn single atoms. Fig. 4 ...
presence of nonelectrochemical steps (e.g., *OO dimer formation/desorption) tends to increase rather than to reduce the thermodynamic overpotential of OER, while the presence of surface defects (e.g., VO defects) probably alters the configuration of adsorbed intermediates to improve the OER ...
(Color online) (a) Schematic configuration of homemade Zn-air battery; (b) discharge curves of Co/Co-Cu-S@SNPCP-CFs-based Zn-air battery at different current densities; (c) discharge and power density curve of Co/Co-Cu-S@SNPCP-CFs and Pt/C catalysts for Zn-air batteries; (d) dis...
2.1. Configuration of aqueous ZABs With respect to the types of electrolytes used, ZABs can be divided into two categories: aqueous ZABs and non-aqueous ZABs. Non-aqueous electrolytes include room temperature ionic liquids and quasi-solid flexible electrolytes. In aqueous ZABs, the normally used...
power systems with simplified configuration and suitable for various environments. Oxygen is known to be a rich source of energy from air and can be used to convert chemical energy into electrical energy through redox reactions. Therefore, combining the chemical energy of oxygen with the ...

maintaining more carbon atoms in both aromatic ring and alkynyl group close to Pt atoms and oxygen atoms in nitro close to Zn could make the configuration more stable. The adsorption configurations of 4-NPA at the Pt isolated-single-atomic-site (Pt–N–C) were also calculated and found that...
FIG. 2 is a schematic view of an interleaved microchannel reactor oriented in a co-current flow configuration. FIG. 3 shows the results of Water-Gas-Shift (WGS) reaction testing for a Pd/Zn/Al2O3 catalyst compared to commercial Shift catalysts. ...
