Computational Geometry, 2006 The authors consider combinatorial and computational issues that are related to the problem of moving coins from one configuration to another. Coins are defined as nonoverlapping discs, and moves are defined as collision free translations, all in the Euclidean plane.

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries
Advanced Functional Materials, EarlyView.Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

Advanced Functional Materials, EarlyView.A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Advanced Functional Materials, EarlyView.Lithium iron phosphate (LFP) accounts for over 50% of the global cathode market, underscoring the need for efficient recycling and regeneration. We propose a dual‐salt carbothermal shock (CTS) strategy using LiI and NaI to in situ repair Li vacancies.

Oesophageal coins invisible on chest radiography: a case report
International Journal of Emergency Medicine, 2017 Background Coins are made of metal, which is generally radiopaque, and so physicians often have the misconception that all coins are detectable by radiography.

Advanced Functional Materials, EarlyView.A Zn2+‐coordinated poly(vinylidene fluoride) binder is shown to suppress Jahn–Teller‐driven Mn dissolution while improving dispersion, wettability, and structural integrity in thick MnO2 cathodes. This simple binder‐engineering strategy enables high‐loading aqueous Zn‐ion batteries with enhanced areal capacity, cycling stability, and practical promise ...
