Effects of Catalyst Synthesis Methods on the Physicochemical Properties of Silica‐Supported Au–Ru Bimetallic Catalysts and their Influence on the Oxidation of Phenols with H2O2

open access: yesChemistryOpen
Herein, silica‐supported Au–Ru catalysts with 5% loading for each metal were prepared by microwave‐assisted loading (MW) and deposition (DP) methods. Au–Ru nanoparticles are obtained on MW‐5Au5Ru while short Au–Ru nanochains are obtained on DP‐5Au5Ru ...

Harnessing Methylselenol (CH3SeH): A Highly Effective Platform for Stimuli‐Responsive Delivery With Therapeutic Potential

open access: yesAdvanced Science, EarlyView.
Tools for controlled selenol delivery are crucial for exploring Se‐related biology and medicine, but compound platforms for triggerable release of CH3SeH remain lacking. Herein, we report the first general triggered platform (TD‐MSe) for efficient cyclization release of CH3SeH in live cells.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Palladium/Heteropoly Acid Catalyzed Oxidative Coupling of 2-Methoxy-1,4-benzoquinone with Arenes

open access: yesJournal of the Brazilian Chemical Society, 2002
Oxidative coupling of 2-methoxy-1,4-benzoquinone and arenes in acetic acid gives methoxyaryl-substituted 1,4-benzoquinones. The reaction is effectively catalyzed by a Pd(OAc)2/heteropoly acid (H9PMo6V6O40 ) redox system with dioxygen as the final oxidant.

Toward Sustainable Smart Packaging: Demonstration of Laser‐Induced Graphene Sensors on Orange‐Based Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
Orange peel waste is directly transformed into biodegradable bioplastic films and converted into electronically active laser‐induced graphene (LIG) sensors through single‐step 450 nm laser scribing. Without requiring conductive inks, metallic coatings, or transfer steps, localized photothermal conversion creates porous 3D graphitic networks with sheet ...

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Electrochemical Control of Scholl Reaction: Arenium Cation Versus Radical Cation Pathways

open access: yesAngewandte Chemie, EarlyView.
Electrochemical control of Scholl reactions allows selective access to the arenium cation and radical cation pathways via low‐potential acidic (LPA) and high‐potential neutral (HPN) conditions, respectively. This control reveals that most substrates react through both pathways, albeit with clear preferences, and provides an experimental foundation for ...

Embedded Morgan Fingerprints for More Efficient Molecular Property Predictions With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
High dimensionality of Morgan fingerprints causes overfitting and slow training. Embedded Morgan Fingerprint (eMFP) compresses this encoding while keeping key structural information intact. Tested on five regression models across three databases for HOMO–LUMO gap prediction, eMFP outperforms standard fingerprints, training faster on large, high ...

Hydrogen‐Bonding Order Associated With Radical Delocalization in Layered Organic Cathode Materials

open access: yesAngewandte Chemie, EarlyView.
“TAQ” and TAPT share the same pyrazine‐based molecular structure but differ in degree of crystallinity. Combined x‐ray scattering, solid‐state NMR, MicroED, and EPR reveal that “TAQ”'s higher crystallinity and ordered hydrogen‐bonding network are associated with enhanced radical delocalization and conductivity, highlighting structural order as a design
