Fluorine polymer probes for magnetic resonance imaging: quo vadis?

, 2019
Over the last few years, the development and relevance of F-19 magnetic resonance imaging (MRI) for use in clinical practice has emerged. MRI using fluorinated probes enables the achievement of a specific signal with high contrast in MRI images. However,

τBu₂SiF-Derivatized D₂-Receptor Ligands: The First SiFA-Containing Small Molecule Radiotracers for Target-Specific PET-Imaging [PDF]

, 2011
The synthesis, radiolabeling and in vitro evaluation of new silicon-fluoride acceptor (SiFA) derivatized D-2-receptor ligands is reported. The SiFA-technology simplifies the introduction of fluorine-18 into target specific biomolecules for Positron ...

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

Advanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

The influence of fluorine substitution on some enzyme mediated reactions [PDF]

, 1997
The replacement of a hydrogen or hydroxy group with a fluorine atom is a popular strategy to alter the activity of biologically important molecules, as their similar sizes mean that such a replacement has little steric impact.

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

Tribological properties of room temperature fluorinated graphite heat-treated under fluorine atmosphere [PDF]

, 2010
This work is concerned with the study of the tribologic properties of room temperature fluorinated graphite heat-treated under fluorine atmosphere. The fluorinated compounds all present good intrinsic friction properties (friction coefficient in the ...

Reversible Calcium Alloying on Bulk and Indium (Sub)‐Micro Negative Electrodes for Calcium‐Based Batteries

Advanced Functional Materials, EarlyView.
Description: Indium metal serves as a reversible calcium‐alloying negative electrode. By transitioning from planar electrodes to powders and (sub‐)micron indium particles, the specific surface area is increased, improving the areal capacity density and cycling stability for calcium‐based batteries.

Novel [18F]-labeled thiol for the labeling of Dha- or maleimide-containing biomolecules

EJNMMI Radiopharmacy and Chemistry, 2022
Background Prosthetic approach for the radiolabeling of biologics with fluorine-18 is a robust strategy and has been employed for many years. It requires fast, biocompatible and selective reactions suited to these fragile molecules. Michael addition of a
