AI Article Synopsis

  • F magnetic resonance imaging (F MRI) is an advanced imaging technique that excels in clinical diagnosis but faces challenges in creating effective fluorine agents.
  • Researchers developed a novel platform called FILAMP, using fluorinated ionic liquids (ILs), which respond to environmental stimuli to release their fluorine payloads.
  • This "turn-on" mechanism allows for enhanced F signals, successfully detecting biological targets at both cellular and animal levels, showcasing its potential for diagnosing and monitoring disease processes.

Article Abstract

F magnetic resonance imaging (F MRI) is a promising technique for molecular imaging and clinical diagnosis, benefiting from its negligible background and unlimited tissue penetration depth. However, the development of F probes with good water solubility and versatile functions for bioresponsive and practical applications remains a challenge. Here, we report fluorinated ion liquids (ILs) as a new type of fluorine agents and build a fluorinated ionic liquid-based activatable F MRI platform (FILAMP), which relies on the phase transition of ILs. Upon exposure to environmental stimulation, coating polymer dissolves or degrades to release the fluorinated ILs payload, which rapidly enhances F signal. This "turn-on" response is verified by the successful detection of biological targets (for example, dysregulated pH and MMP overexpression) at the cellular level and in mice, demonstrating the potential of FILAMP as a robust activatable F probe for diagnosis and monitoring of biological and pathological processes.

High Correlation Between Li Solvation Energy and Li Ionic Conductivity in Lithium Metal Battery Electrolytes.

Int J Mol Sci

December 2024

Department of Energy and Materials Engineering and Advanced Energy and Electronic Materials Research Center, Dongguk University-Seoul, Seoul 04620, Republic of Korea.

In lithium metal batteries, accurately estimating the Li solvation ability of solvents is essential for effectively modulating the Li solvation sheath to form a stable interphase and achieve high ionic conductivity. However, previous studies have shown that the theoretically calculated Li binding energy, commonly used to evaluate solvation ability, exhibits only a moderate correlation with experimentally measured ionic conductivity (R = 0.68).

Article Synopsis
  • The study uses molecular dynamics simulations to analyze how different termination functional groups on TiCT MXene membranes affect the behavior of nearby water molecules and foulants.
  • Results indicate that a denser water layer forms near hydroxyl (OH) terminated membranes compared to fluorine (F) or oxygen (O) terminations, influencing the binding of alginate monomers.
  • Steered molecular dynamics simulations reveal that M alginate monomers bind more strongly to O terminated surfaces, while binding is weak near OH terminations due to hydration water, with calcium ions enhancing fouling via contact and solvent-shared ionic pairs.

Pentafluoroorthotellurate Uncovered: Theoretical Perspectives on an Extremely Electronegative Group.

Inorg Chem

January 2025

Departamento de Química Física and Instituto de Biocomputación y Física de Sistemas Complejos (BIFI), Universidad de Zaragoza, Zaragoza 50009, Spain.

Article Synopsis
  • The pentafluoroorthotellurate group (-OTeF, teflate) is a potent electron-withdrawing substitute for fluoride, known for its stability and size, which helps avoid bridging ligand behavior.
  • This study employs advanced Quantum Chemical Topology methods to analyze the electronic structure and bonding of the teflate group, comparing its electronegativity with halogens and investigating the interactions in various XOTeF systems.
  • Findings reveal that while teflate exhibits strong electron-withdrawing abilities akin to fluorine, its bonding is predominantly ionic and shares similar electronegativity traits with other O-donor groups.

Non-Flammable fluorinated gel polymer electrolyte for safe lithium metal batteries in harsh environments.

Compared to liquid electrolytes, gel polymer electrolytes (GPEs) offer enhanced safety and represent an up-and-coming option for high-energy-density lithium metal batteries (LMBs). However, several challenges hindered the practical application of GPEs for LMBs, such as low ionic conductivity at room temperature, decomposition at high voltage, and poor interfacial compatibility with lithium anode. In this study, a non-flammable fluorinated GPE was synthesized using 2,2,2-trifluoroethyl acrylate (TFEA) and ethoxylated trimethylolpropane triacrylate (ETPTA) as precursor materials, with succinonitrile (SN) incorporated as a plasticizer and a dual-salt system of lithium bis(trifluoro-methane) sulfonimide and lithium difluoroxalate borate.

Fluorination from Surface to Bulk Stabilizing High Nickel Cathode Materials with Outstanding Electrochemical Performance.

High nickel layered oxides provide high energy densities as cathodes for next-generation batteries. However, critical issues such as capacity fading and voltage decay, which derive from labile surface reactivity and phase transition, especially under high-rate high-voltage conditions, prevent their commercialization. Here we propose a fluorination strategy to simultaneously introduce F atoms into oxygen layer and create a F aggregated interface.
