Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization

ChemistryEurope, EarlyView.
A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

Preparing an Exsolvable Ru‐Substituted LaFeO3 Perovskite With High Surface Area From a Self‐Sacrificial Polymer Template: A Versatile Strategy for Enhanced Catalytic Performance

Chemistry – A European Journal, EarlyView.
High‐surface‐area LaFe0.9Ru0.1O3 is prepared by infiltration of porous Amberlite XAD16 polymer beads. Ru exsolution of this perovskite material leads to a supported catalyst with small Ru particles, exhibiting promising catalytic performance propane combustion.

Strategies to control Cirsium arvense under organic farming conditions [PDF]

, 2005
Three strategies for controlling Cirsium arvense including (1) repeated stubble tillage with subsequent forage crop cultivation, (2) repeated mowing of a grass-clover ley, and (3) forage crop cultivation following a grass-clover ley ploughed in May/June (

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

Effects of Elevated Substrate-Ethylene on Colonization of Leek (\u3cem\u3eAllium porrum\u3c/em\u3e) by the Arbuscular Mycorrhizal Fungus \u3cem\u3eGlomus aggregatum\u3c/em\u3e [PDF]

, 2002
There are very few studies of hormonal regulation of arbuscular mycorrhiza formation that include the gaseous hormone ethylene. Ethylene is considered inhibitory to the formation of arbuscular mycorrhizae; however, very low concentrations may promote ...

Liquid‐Phase Synthesis of Halide Solid Electrolytes for All‐Solid‐State Batteries Using Organic Solvents

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops a scalable and universal liquid‐phase synthesis method of halide solid electrolytes using nitrogen‐containing solvents. The Li2YCl5−yBry (y = 0, 2, and 5) solid electrolytes synthesized via pyridine solvent exhibit an ionic conductivity over 1 × 10−4 S cm−1 at 25 °C.
