Capitalizing on ether groups, solvent-free synthesis produces ionic liquid integrated solid electrolytes for flexible capacitors delivering high energy and power.
The structural features of humic acids extracted from Zhaotong and Mile lignites were analyzed using comprehensive spectral analyses including UV-vis, FTIR, CP/MAS 13C NMR, XRD and XPS.
This purification process may be described by the unreacted shrink core model with solid resultant (inert material) and fixed particle size, which is carried out by the action of nitric acid solution on the precipitated silica obtained from yellow phosphorus slag which was leached with phosphoric acid. The study results indicate that the purification process is a chemical reaction controlling step and its apparent activation energy E a is 30.354 kJ/mol, with reaction order 0.6746.Le présent procédé de purification peutêtre décrit par le modèle du noyau rétrécissant non réagi avec la résultante solide (matériau inerte) et la taille de particule fixe. Ce procédé est obtenu par l'action d'une solution d'acide nitrique sur une silice précipitée obtenueà partir des scories de phosphore lavéesà l'acide phosphorique. Les résultats de l'étude montrent que le procédé de purification est uneétape de contrôle de la réaction chimique, dont l'énergie d'activation apparente Ea est de 30,2354 kJ/mol, avec un ordre de réaction de 0,6746.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
