Beyond Traditional RAFT Polymerization: Emerging Strategies and Future Perspectives; A Third Update
This review explores recent advances in the past five years for non‐traditional RAFT polymerization, focusing on new activation strategies, sustainable depolymerization, and integration with automated and AI‐driven synthesis. Together, these innovations advance polymer chemistry and reveal how the pieces of the non‐traditional RAFT puzzle are steadily ...

Volumetric additive manufacturing allows to print parts extremely fast, but is so far is limited by the build volume of the printers. The foaming materials presented here allow to expand printed parts up to 500% reaching densities of 0.16 g cm−3 as well as providing shape memory properties enabling the creation of lightweight, functional parts ...

Effect of TMAH on the rheological behavior of alumina slurries for gelcasting
Tetramethyl ammonium hydroxide (TMAH) has been demonstrated to increase solids loading effectively and to accelerate gelling rate of alumina slurries gelled by Isobam (a copolymer of isobutylene and maleic anhydride) system.

Skeletal editing of alkenes via the cascade cleavage of C(sp2)═C(sp2) and C(sp3)─C(sp3) bonds, enabling the insertion of the nitrogen atom and thereby the synthesis of lactam and amide derivatives using nitroarenes as nitrogen atom insertion reagents under light irradiation.

Expanding the Alkene‐Forming Capability of the Pseudomonas Savastanoi Ethylene‐Forming Enzyme
Bump‐and‐hole studies on the Pseudomonas savastanoi ethylene‐forming enzyme (PsEFE) enable formation of low levels of alkene products other than ethylene from naturally occurring 2‐oxoglutarate derivatives. The results show that plants and/or microorganisms have potential for enzyme‐catalyzed production of propylene and 1‐butylene, potentially to exert

ABSTRACT Upconverting nanoparticles (UCNPs) have attracted much attention in nanomedicine due to their ability to upconvert photons. However, their adverse effects hinder the biomedical applications. In this paper, bisphosphonate‐modified poly(isobutylene‐alt‐maleic acid)‐graft‐poly(N,N‐dimethylacrylamide)‐coated NaYF4:Yb,Er,Pr UCNPs (UCNP@PIMAPDMA ...

Impact of Extrusion Pretreatment on Polypropylene Waste Pyrolysis
Schematic of the recycling process, highlighting the extrusion (450°C, 2 min) pretreatment applied to postconsumer PP samples before pyrolysis at 425°C–475°C for 15–45 min. ABSTRACT The present study investigates the influence of extrusion pretreatment on the pyrolysis of post‐consumer polypropylene (PP), expanding upon previous findings related to the
