Abstract

Superstable Separators (solid electrolytes) are required for novel aqueous-based high-energy lithium batteries, to enable their long-term operation. In their Communication on page 129 ff., C. Ma, M. Chi, et al. demonstrate excellent stability and conductivity of the cubic Li7La3Zr2O12 garnet in neutral and strongly basic solutions, indicating it may be the ideal solid electrolyte for next-generation high-energy lithium batteries.

Conformational Analysis In their Communication on page 102 ff., A. J. Wand et al. investigated the aromatic side chains of ubiquitin, which show a sharp thermal dynamical transition at approximately 312 K.1 Redox-Switchable Catalysis The development of a ferrocenylphosphane ruthenium(II) catalyst that can be reversibly switched off and on through chemical oxidation and reduction is described by E. Hey-Hawkins et al. in their Communication on page 311 ff.1 Thiol Click Reaction The reversible photoactivated thiol formation of spirothiopyran confers spatiotemporal sequential control to a thiol click reaction, as described by L. Zhu et al. in their Communication on page 174 ff.1
