The compact organization of hydrophilic guest ions facilitates water-assisted ion-conduction in all the compounds. The dense packing of the compounds imparts high ion-conducting ability and minimizes the possibility of fuel crossover, making this approach promising for design and development of compounds as potential components of energy devices. This work presents the first report of evaluating ion-conduction in a purely metal-carbonate framework, which exhibits high ion-conductivity on the order of 10(-2) S cm(-1) along with very low activation energy, which is comparable to highly conducting well-known crystalline coordination polymers or commercialized organic polymers like Nafion.}, doi = {10.1021/acs.inorgchem.7b01217}, author = {Manna, Biplab and Desai, Aamod V. and Illathvalappil, Rajith and Gupta, Kriti and Sen, Arunabha and Kurungot, Sreekumar and Ghosh, Sujit K.} } @article {49437, title = {Unconventional hole doping of S = {\textonehalf} kagome antiferromagnet CoCu3(OH)6Cl2}, journal = {Advanced Physics Research}, volume = {3}, year = {2024}, month = {SEP}, type = {Article}, abstract = {

Geometrically perfect S = {\textonehalf} kagome lattices with frustrated magnetism are typically electrical insulators. Electron or hole doping is predicted to induce an exotic conducting state including superconductivity. Herein, an unconventional strategy of doping an S = {\textonehalf} kagome lattice CoCu3(OH)6Cl2\ is adopted {\textendash} a structural analogue of a well-known quantum spin liquid (QSL) candidate herbertsmithite (ZnCu3(OH)6Cl2) {\textendash} by integrating it with reduced graphene oxide (rGO) via in situ redox chemistry. Such an integration drastically enhances the electrical conductivity, resulting in the transformation of an insulator to a semiconductor, corroborating the respective density of states obtained from the density functional theory calculations. Estimation of the magnetic moments, data on the Hall-effect measurements, Bader charge analysis, and photoemission signals, altogether provide a bold signature of remote hole doping in CoCu3(OH)6Cl2\ by rGO. The remote doping provides an alternative to the site doping approach to impart exotic electronic properties in spin liquid candidates, specifically, the generation of topological states like Dirac metal is envisioned.
