Different compositions of 3d transition metals with multiple characteristics (shown in Scheme 1), will result in high compositional diversity and therefore tunable their electrochemical performance as cathodes. Although V and Cr are relatively abundant elements in the Earth’s crust, V3+ and Cr3+ base...
Multiple metals (Fe, Co, Ni) modulated sulfide with the substrate of PBA precursor was carefully designed and served as anodes for both lithium- and sodium- ion batteries. The excellent electrochemical performances of the obtained anodes are attributed to the following merits: (a) the N-doped ...
Each element has unique oxidation states, with the most common state bolded in the periodic table. Elements can also have multiple possible oxidation states. Oxidation occurs in many elements, but not all. Some nonreactive elements like Helium (He) remain in a neutral oxidation rate of 0, mean...
In the final report of a two-year investigation released last week, the US Senate raised charges of alleged manipulating of oil, aluminum, and coal markets by Wall Street banks. In addition to other regulatory burdens and listless markets, these factors have led many banks to give up physical...
This forward-looking metric is calculated based on a model, which is dependent upon multiple assumptions. Also, there are limitations with the data inputs to the model. Importantly, an ITR metric may vary meaningfully across data providers for a variety of reasons due to methodological choices (...
1a and b, both systems comprise multiple sub-layers. Most importantly, a 2D kagome sub-layer is formed from V atoms, coexisting with Sb sub-layers. While these are similar in both systems, differences arise from the alkali atoms A. In the monolayer (bulk) system, alkali metals ...

132 Hydrogen sulfide and selenide have widely been employed in the synthesis of metal chalcogenides through reactions with aqueous metal cations, metal oxides, and sol–gel processing.133 Most procedures require multiple steps, extended processing, carefully tailored precursors, and/or the use of ...
