Electrolytic Partial Fluorination of Organic Compounds. 64. Anodic Mono- and Difluorination of Thiazolyl Sulfides

open access: yes, 2016
The anodic fluorination of 2-thiazolyl methyl sulfide, 2-thiazolyl propargyl sulfide, and 2-thiazolyl acetonyl sulfide was successfully carried out to provide the corresponding 5-fluorothiazole and 2,5,5-trifluorothiazoline derivatives.

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...

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

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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

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

open access: yesAdvanced 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.
