Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

Chemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Carboxylate–Probase Catalyzed Favorskii Reaction

Chemistry – A European Journal, EarlyView.
Stronger together: A combination of a carboxylate catalyst and a silylating agent generates a stronger base catalyst for a metal‐free catalytic addition of alkynes to aldehydes and ketones under chemoselective, O‐silylative conditions. The reaction is proposed to proceed via quaternary ammonium (Q+) cation – acetylide anion ion pairs, with chiral ...

N-fixing tree species promote the chemical stability of soil organic carbon in subtropical plantations through increasing the relative contribution of plant-derived lipids

Forest Ecosystems
Biodiversity experiments have shown that soil organic carbon (SOC) is not only a function of plant diversity, but is also closely related to the nitrogen (N) -fixing plants.

Phosphorus enrichment mediates the responses of plant lignin and microbial necromass accumulation to nitrogen addition in subalpine forest soil

Geoderma
It is widely recognized that increased nitrogen (N) and phosphorus (P) inputs play critical roles in plant carbon (C) inputs and microbial growth and activity, thereby profoundly affecting the composition and dynamics of soil organic C (SOC).
