Anions And Cations

Dendrite-free Zn anodes are achieved by using the highly efficient electrolyte additives based on polyoxometalate. Both of the anions and cations of polyoxometalate play important roles in inhibiting the growth Zn dendrites.

Anions And Cations

In-situ electron microscopy has gained considerable attention in recent years. It provides a “live” view of a material or device under study at various length scales. For example, by heating or cooling a sample one can study structural change at the atomic scale to understand the driving forces and mechanisms of phase transitions. By applying electric and magnetic fields on a ferroelectric or magnetic architecture in operation, one can directly observe how electric and magnetic domains switch, how anions and cations shift their positions, and how spins change their configuration across a domain wall, aiding the development of better electromagnetic devices. In the study of photovoltaic devices and junctions, a major challenge is to directly correlate light-induced electric currents with local structural inhomogeneities and dynamics. Such a capability would allow us to evaluate the performance of individual p-n junctions and to improve optoelectronic efficiency.

The title salt, C19H18N3 +·NO3 −, has two symmetry-independent cations and two symmetry-independent anions in the asymmetric unit, with almost identical geometries. Bond lengths and angles within the guanidinium unit are close to those expected for a Csp 2 atom. Intermolecular hydrogen bonds link anions and cations, forming chains that run along the c axis.
