Dual‐Network Restriction in Dense EDTA‐Metal Coordination Polymers for Highly Efficient and Stable Organic RTP in Aqueous System

open access: yesAggregate, Volume 7, Issue 2, February 2026.
Dense composites with excellent water stability and phosphorescence performance are constructed using EDTA‐metal coordination polymers as the host matrix. Based on the synergistic confinement effect of the coordination and non‐covalent dual‐network within the composites, a phosphorescence quantum yield as high as 53% is achieved, enabling their ...

Versatile Photofunctionalization of Carbon Nanotubes via [4 + 2] Cycloaddition: A Facile Route to Hybrid Nanomaterials

open access: yesSmall Science, Volume 5, Issue 11, November 2025.
A [4 + 2] photocycloaddition of aryl cyclobutyl amines on carbon nanotubes is presented. A photocatalyst oxidizes the cyclic moiety to generate an active species trapped by the nanotube π‐cloud. The method functionalizes nanotubes of different characteristics and is tolerant to different functional groups decorating the amine.

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

open access: yesChemCatChem, Volume 17, Issue 15, August 7, 2025.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Molecular characterization of cellulose synthase (CesA) genes and impact of mutations on fungicide resistance in oomycetes [PDF]

open access: yes, 2012
Many oomycetes are important pathogens of plants (e.g. arable crops, fruit and forest trees), animals or microbes and, upon attacking their hosts, cause considerable economic damage mainly in agriculture and aquaculture.
