Initiator-free synthesis of semi-interpenetrating polymer networks via Bergman cyclization [PDF]
Semi-interpenetrating polymer networks (semi-IPNs), composed of two or more polymers, forming intertwined network-architectures, represent a significant type of polymer combination in modern industry, especially in automotive and medical devices. Diverse

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, EarlyView.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Multi‐Responsive PAA/PNIPAM Semi‐IPN Hydrogel Properties Controlled by PAA Topology
Macromolecular Rapid Communications, EarlyView.Polymer topology governs hydrogel behavior in semi‐interpenetrating networks. Cyclic poly(acrylic acid) enables controlled pH‐responsive swelling, improved stability, and enhanced deformability compared to linear analogues, while linear systems show higher strength during thermal de‐swelling.

Interpenetrating Polymer Networks: Processing, Properties and Applications
, 2013 Interpenetrating polymer networks (IPNs) are defined as combination of two or more polymers in network form with at least one of which is polymerised and/or crosslinked in the immediate presence of the others.

Modelling Suicide‐Related Communication Dynamics: A Socio‐Cybernetic Framework for Governance
Systems Research and Behavioral Science, EarlyView.ABSTRACT Suicide‐related phenomena (SPS) are often approached through individual‐level risk factors or moral framings, yet their population‐level dynamics depend critically on how ‘suicide’ becomes observable, circulates and is governed across functionally differentiated systems.

Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials
Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...
