Introducing Diradicaloid Thiele's Hydrocarbon Derivatives as Ligand in Transition Metal Chemistry. [PDF]

Angew Chem Int Ed Engl
N‐doped Thiele's hydrocarbon derivative is introduced as a ligand for the synthesis of mono‐ and bimetallic rhodium complexes as well as cyclometalated iridium complexes. These compounds constitute the first metal complexes based on a Thiele's hydrocarbon (or p‐quinodimethane) derivative and, to the best of our knowledge, the first cyclometalated ...

Fully Synthetic, Biomimicking Polysulfates With Tunable Anticoagulant and Endothelial Cell-Selective Bioactivity. [PDF]

Macromol Biosci
Sulfated PHEMA‐based polyelectrolyte brushes are introduced as a reductionist platform to probe glycosaminoglycan‐inspired bioactivity. High charge density governs growth factor interactions and is associated with distinct vascular cell responses, enabling balanced endothelial and smooth muscle cell co‐culture.

Construction of a MOF-Based Snap-Top Delivery Nanosystem for Powerful Dual-Responsive Synergistic Colitis Treatment. [PDF]

Adv Sci (Weinh)
A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Deployable 3D-Printed Vascular Stent with Surface-Catalysed Endogenous Nitric Oxide Generation. [PDF]

Adv Mater
A deployable 3D‐printed vascular stent was fabricated with surface‐catalyzed endogenous nitric oxide generation, representing a promising new direction for stent development. The stent can be remotely controlled by magnetic force in its compressed state and fully deployed at the target site using an untethered heat source, potentially eliminating the ...

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides. [PDF]

J Pept Sci
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...

Multicompartment Nanostructures as Templates for Multimetallic Hybrid Materials

Small Science, 2023
ABC triblock terpolymers are promising soft templates for organic/inorganic hybrids because of their ability to form nanostructures with complex shapes, multiple compartments, and precisely localized chemistry. Exemplified on multicompartment nanofibers (

The Shift from Affix to Clitic in the History of the English Genitive: Evidence from John of Trevisa’s Polychronicon

SELIM
In this article I address the question of the change in grammatical nature for the English genitive from inflectional affix to clitic. I focus on the rise of the group genitive, a construction in which the mark for possession is not attached to the head

The Investigation of the Deactivation of the Metal‐Modified ZSM‐5 Zeolites for the Catalytic Dehydration of Glycerol

Carbon and Hydrogen, Volume 28, Issue 3, Page 360-373, September 2026.
During the glycerol dehydration over ZSM‐5 zeolite, the modification by metal promoters results in the suppression of the bicyclic and tricyclic aromatics over the modified ZSM‐5 zeolite catalysts. However, the issue of the fast deactivation still remains an apparent challenge, which requires more different perspectives to understand the deactivation ...

Role of Core and Surface States Electronic Structure in the Tunable Optical Properties of Nitrogen‐Doped Carbon Dots

ChemPhotoChem, Volume 10, Issue 9, September 2026.
This work provides insight into the photoluminescence mechanism of nitrogen‐doped carbon dots derived from PTCDA and urea. The materials exhibit a dual‐emission system composed of dominant, excitation‐independent core emission and secondary excitation‐dependent surface/state emission.
