Selective Degradation of Polyurethanes in Mixed Plastic Wastes via Ir‐Catalyzed Hydrogenolysis

open access: yesAngewandte Chemie, EarlyView.
The selective degradation of polyurethanes in mixed plastic wastes with polyesters and polyamides was achieved using H2 as a reactant, enabling simultaneous recovery of diformamides and polyols arising from polyurethanes and separation of polyesters and polyamides without any degradation.

Integration of Redox‐Active Polyoxovanadate Clusters into PMMA: Structure, Nanoscale Organization and Multilevel Redox Switching

open access: yesAdvanced Electronic Materials, EarlyView.
Solvent‐processable polyoxovanadate–PMMA nanocomposites exhibit concentration‐dependent 2D and 3D organization on gold surfaces, while retaining multilevel redox switching at room temperature. These hybrids bridge nanoscale functionality and macroscopic measurement, establishing a versatile platform for hybrid molecular–polymer memory materials ...

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

open access: yesAngewandte Chemie, EarlyView.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, EarlyView.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

3D‐Printable Nanoporous Thermosets via Disulfide‐Based Polymerization‐Induced Microphase Separation

open access: yesAngewandte Chemie, EarlyView.
α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.
