2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices

Small, EarlyView.
This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

Tetrazine Functionalized Graphene Enables Capture of Ultra‐Low Concentrations of Biomacromolecules

Small, EarlyView.
A novel method for covalent modification of monolayer graphene utilizing tetrazine containing diazonium salt is demonstrated. The modified graphene bearing tetrazine moieties undergoes inverse electron demand Diels‐Alder reactions with trans‐cyclooctene‐linked molecules, enabling bioorthogonal attachment of nanobodies that selectively capture EGFP ...

Recyclable Printed Liquid Metal Composite for Underwater Stretchable Electronics

Small Science, Volume 5, Issue 5, May 2025.
This work presents a multifunctional liquid metal (LM) microdroplet‐based composite with a custom‐designed block copolymer as the matrix, optimized for printing. The composite exhibits high conductivity, stretchability, durability in dry and aqueous environments, and recyclability of LM using green solvents. These properties highlight its potential for

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Fluorescence Spectrum of Anisole Vapour [PDF]

Nature, 1962
THE fluorescence spectrum of anisole in the vapour state has been developed following the technique of Bass and Sponer1. The vapour was contained in a cell fitted with quartz windows and the fluorescence was excited by the radiation from condensed spark between manganese electrodes. The spark was produced by a high-voltage transformer rated 1/4 kW.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

British Journal of Pharmacology, EarlyView.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

New Phytologist, EarlyView.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.
