What is the chemical behaviour of the parent elements in period 3 chlorides in relation to water (hydrolysis) and solubility (dissolution)? What is the atomic structure of acetylsalicylic acid? How can we measure standard electrode potentials? What do these measurements s...
In this work, homovalent doped Na3V2(PO4)2F3/C cathode was synthesized by a fast reduced sol-gel method where CrF3was used as dopant. The crystal structure, morphology, electrical conductivity, electrochemical performance and formation mechanism of Na3V2-xCrx(PO4)2F3/C were comprehensively dis...
The structure of K6Bi13(PO4)15 can be described as a three-dimensional (3D) network composed of the Bi-O polyhedra and PO4 tetrahedra with K atoms filling in the space to balance the residual charges. K5Bi(P2O7)2 features 2D [BiP4O14]∞ layers built by the BiO6 octahedra and P...
structure and composition than the 2+ and 4+ valance states. For these reasons, the majority of Mn5+emitting host materials contain electropositive ions such as alkaline earth metals and PO43-and VO43-groups (or SiO44−group with a charge compensation). The typical examples of such material...
