Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

RAFT Copolymerization of DMAEA and AETAC Toward Charge‐Shifting Copolymers With Tunable Heparin Complexation

Macromolecular Rapid Communications, EarlyView.
Copolymers based on charge‐shifting (DMAEA) and permanently charged (AETAC) cationic acrylates were copolymerized via the RAFT process to achieve polycations with well‐defined composition. Moderate content of AETAC did not affect hydrolysis rates but significantly enhanced heparin binding.
