Phytate and cation binding activity
… of phytate on the absorption of di(poly)valent cations and the interactions between phytate and divalent cations have become more important. In this study, phytate-cation(s) complexation interaction were studied in the relation to the pH, the concentration of the available cation(s), and the …

An investigation of cation-exchange in aqueous pyridine
… pyridine solutions of the alkaline earth metal cations. The ion-exchange phenomena investigated included: swelling, preferential sorption of solvent and selectivity variations with loading, degree of neutralization of the resin, solvent composition and choice of solution phase anion. The …

The reactivity and cation exchange of MOF-5
… MOF-5 can be derivatized with redox-active cations for subsequent use in coordination chemistry and small-molecule activation. Rather than reproduce known metal species, this work harnesses the intrinsic properties of the MOF-5 lattice to isolate species that are difficult or impossible to …

Cation-disordered oxides for rechargeable lithium battery cathodes
… rechargeable lithium batteries for complex applications such as in electric vehicles or in grid energy storage. Nearly all high-energy density cathode materials for rechargeable lithium batteries have been sought from well-ordered close-packed oxides in which lithium and transition metal ions …

Layered Double Hydroxides as Anion- and Cation-Exchanging Materials
… the LDH. The ability of LDH to incorporate metal cations or any ions/molecules/complexes, that have a postive charge, have not been previously investigated, mainly due to the chemical and physical nature of LDH. The possibility of cationic incorporation with LDH would most likely occur by surface …

Cation radical induced oxidative chemistry of hydrazones and oximes
Electron transfer reactions of cation radicals have drawn much interest (1). Shine and Sugiyama were the first to observe that alkyl radicals were formed by an initial electron transfer step in reactions of thianthrene cation radical with organomercurials (2). The possibility that thianthrene …
