Mechanochemical Synthesis of Lead‐Free Halide Layered Double Perovskites: A Green and Scalable Approach

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Herein we report a facile, green, and scalable synthetic alternative for the obtention of layered double perovskites (LDPs) via mechanosynthesis. This approach allows for the synthesis of phase‐pure LDPs in batches of up to 5 g within minutes. To our knowledge, this represents the largest scale and fastest synthesis of these materials reported to date.

Catalytic High‐Speed Reactive Extrusion for Polyethylene Mechanochemical Upcycling

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Twin screw extrusion at high speeds is a mechanochemical strategy for polyethylene recycling that takes advantage of high shear rates and intimate mixing with catalyst to induce structural transformations. This process intensification approach can lower the thermal energy requirements of chemical recycling, contributing to more economically viable and ...

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic

Mechanochemical Difluorocarbene‐Mediated C(sp3)–N Bond Cleavage and In Situ Formylation of Tertiary Amines

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
A sustainable mechanochemical method for C(sp3)–N bond cleavage and in situ N‐formylation of tertiary amines is developed using a difluorocarbene precursor. The transformation proceeds under mild ball‐milling conditions, demonstrating a broad substrate scope, excellent functional group tolerance, and efficient conversions of diverse aliphatic and ...

Opportunities of Highly Oxidized Single‐Walled Carbon Nanotubes for Electrochemical and Electromechanical Applications

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
This review presents recent advances in highly oxidized SWCNTs, which retain sp2 structural integrity while offering abundant surface functionalities and dispersant‐free processability. It highlights controlled oxidation strategies, enhanced interfacial reactivity, and their broad applicability—from wet‐spun fibers and chemical sensors to ...
