Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

European Journal of Inorganic Chemistry, EarlyView.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...

Micro‐ and Nanopatterning of Highly Conductive PEDOT Thin Films

Macromolecular Rapid Communications, EarlyView.
This work presents micro‐ and nanoscale fabrication strategies for organic thin‐film devices using non‐commercial PEDOT synthesized by V2O5‐mediated oxidative polymerization. Optimized films show controlled thickness and tunable conductivity. At the nanoscale, nanosphere lithography enables large‐area hexagonally packed PEDOT nanopillar arrays down to ...

Corrosion and Passivation: An Intimate Struggle for Durable Non‐Aqueous Multivalent Metal Batteries

National Materials, EarlyView.
In multivalent metal batteries, corrosion and passivation are intrinsically coupled. Anodes and current collectors pose conflicting interfacial demands: ion‐ versus electron‐conductivity. This review deciphers their intricate interplay and discusses current strategies to balance these mechanisms for achieving durable battery performance.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
