One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

open access: yesAngewandte Chemie, EarlyView.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

3D‐Printed Supramolecular Eutectogels—Tunable Conductive Wires for Soft Electric Circuits

open access: yesAdvanced Electronic Materials, EarlyView.
Soft, flexible gels based on self‐assembling low‐molecular‐weight gelators in deep eutectic solvents can be 3D‐printed into electrical circuits using a simple wet‐spinning approach, acting as tunable conducting components, and having potential future applications in bionanoelectronics.

Design and optimization of processes for recovering rare earth elements from end‐of‐life permanent magnets

open access: yesAIChE Journal, EarlyView.
Abstract Recovery of rare earth elements (REEs) from end‐of‐life (EOL) products represents a strategic opportunity to strengthen the domestic supply chain for rare earth elements. This work presents a superstructure‐based optimization framework for finding the most economical processing pathway for different EOL rare earth permanent magnets (REPMs ...

The natural ways of degradation of pesticides based on 2,4-dichlorophenoxyacetic acid [PDF]

open access: yes, 2016
To increase crop yields by destroying weeds the separate group of pesticides exist, that is called herbicides. Among the herbicides based on chlorphen oxalcanecarboxylic acids products of sodium and ammonium salts, as well as 2,4-dichlorophenoxyacetic ...

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

Involvement of several transcriptional regulators in the differential expression of tfd genes in Cupriavidus necator JMP134 [PDF]

open access: yes, 2009
Cupriavidus necator JMP134 has been extensively studied because of its ability to degrade chloroaromatic compounds, including the herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and 3-chlorobenzoic acid (3-CB), which is achieved through the pJP4 ...
