Microplastics in Agricultural Soil: Fate, Impacts, and Bioremediation by Earthworms

Journal of Plant Nutrition and Soil Science, EarlyView.
Microplastics enter the soil through various means, including the degradation of plastic film mulch, waste from cosmetics industries and municipalities, and the use of bioplastic seed coatings. These microplastics disrupt soil structure, microbial activity, enzyme function, and plant growth.

Cationic Photopolymerization of Biobased Oxetane Monomers Obtained from Adipic, Itaconic, and Citric Acid Functionalization

Macromolecular Chemistry and Physics, EarlyView.
Cationic photopolymerization of oxetane‐functionalized derivatives of adipic, itaconic and citric acids were investigated. FT‐IR and photo‐DSC analysis revealing high reactivity in all monomers, reaching nearly complete conversion within 90 seconds. The UV‐Cured films were fully characterized. The findings demonstrate the potential of bio‐based oxetane
