Mixed eldfellite compounds \ce{Na(Fe_{1/2}M_{1/2})(SO4)2} (M = Mn, Co, Ni): A new family of high electrode potential cathodes for the sodium-ion battery
Gum-Chol Ri, Song-Hyok Choe, Chol-Jun Yu
Natural abundance of sodium and its similar behavior to lithium triggered recent extensive studies of cost-effective sodium-ion batteries (SIBs) for large-scale energy storage syst…
Influence of water intercalation and hydration on chemical decomposition and ion transport in methylammonium lead halide perovskites
Un-Gi Jong, Chol-Jun Yu, Gum-Chol Ri +4
The use of methylammonium (MA) lead halide perovskites \ce{CH3NH3PbX3} (X=I, Br, Cl) in perovskite solar cells (PSCs) has made great progress in performance efficiency during recen…
Ab initio study of sodium cointercalation with diglyme molecule into graphite
Chol-Jun Yu, Song-Bok Ri, Song-Hyok Choe +3
The cointercalation of sodium with the solvent organic molecule into graphite can resolve difficulty of forming the stage-I Na-graphite intercalation compound, which is a predomina…
Ab initio Investigation of Adsorption Characteristics of Bisphosphonates on Hydroxyapatite (001) Surface
Mun-Hyok Ri, Yong-Man Jang, Chol-Jun Yu +1
The structures of some bisphosphonates (clodronate, etidronate, pamidronate, alendronate, risedronate, zoledronate, minodronate) were obtained and analyzed, and their adsorption en…
