A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers
Angewandte Chemie, EarlyView.A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

Recycling of Polyamide from Scrap Tyres as Polymeric Composites
Research in Agricultural Engineering, 2015 Rubber granulate, metal waste and textile waste (polyamide fibres) come into the mechanical process of waste tyres recycling. The pollution and degradation processes are problematic in using of secondary raw material.

Advanced Science, EarlyView.We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing
Advanced Electronic Materials, EarlyView.By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...
