Cationic Point Defect Fluoride to Improve Reaction Kinetics in (All) Solid-State Li Batteries

Seonghee Jeong, Dong-Il Kim, Myeongsoo Kim, Hyejin Kwon et autres

Nickel-rich cathode materials (NCM) have emerged as promising candidates for lithium-ion batteries (LIBs) and all-solid-state batteries (ASSBs) due to their high reversible capacity (>200 mAh g –1 ). However, surface side reactions with liquid and solid electrolytes during cycling increase interfacial resistance …

Highly Conductive Li‐Excess Oxide to Facilitate Durable Interfaces in All‐Solid‐State Batteries

Jaewoo Jung, Min Jae You, Yoojin Hong, Myeongsoo Kim et autres

Abstract All‐solid‐state batteries (ASSBs) have garnered significant attention as advanced energy storage systems due to their superior energy density and intrinsic safety, enabled by the incorporation of solid electrolytes instead of conventional liquid electrolytes in lithium‐ion batteries (LIBs). However, the commercialization of …

All-hydrocarbon, all-conjugated cycloparaphenylene-polycyclic aromatic hydrocarbon host-guest complexes stabilized by CH−π interactions

Hyejin Kwon, Carson J. Bruns

Polycyclic aromatic hydrocarbons (PAHs) are promising nanocarbon materials with diverse optoelectronic properties, yet they also pose concerning environmental and health risks. Despite the ubiquity of PAHs in the environment (crude oil, emissions, and biomass), most supermolecules rely on heteroatoms for stability. We …

Redox-switchable host–guest complexes of metallocenes and [8]cycloparaphenylene

Hyejin Kwon, Carson J. Bruns

-phenylene units. This work shows that CH-π bonding can be generalized as a driving force for CPP host-guest complexes and combined with other supramolecular forces to enhance stability. Owing to their semiconducting nature, amenability to functionalization, and reversible redox-dependent behavior, the [8]CPP-metallocene …

Solar Freckles: Long-Term Photochromic Tattoos for Intradermal Ultraviolet Radiometry

Jesse L. Butterfield, Sean P. Keyser, Karan Dikshit, Hyejin Kwon et autres

Abstract While tattooable nanotechnology for in-skin sensing and communication has been a popular concept in science fiction since the 1990s, the first tattooable intradermal nanosensors have only emerged in the past few years, and none have been demonstrated in human skin. We …
