For the block copolymer, 2 kDa PEG monohydroxy terminated was used with 1% PPTS (see experimental section for the detailed description), (b) the dual stimulus-mediated degradation of the polymers ...

Photochemical dissolution of buoyant microplastics to dissolved organic carbon: Rates and microbial impacts. Journal of Hazardous Materials, 2020; 383: 121065 DOI: 10.1016/j.jhazmat.2019.121065 ...

The vanillin derivative developed by the team absorbs light at 300 nm and enters into an excited state. This leads to a chemical reaction that triggers the degradation of the polymer. Because this ...

By integrating an extensive range of photochemical parameters, such as water depth and dissolved organic carbon (DOC) levels, the research reveals key regional variations in pollutant degradation.

Analysts interested in measuring the degradation of molecules due to photodegradation should consider using a photochemical reactor. There are two photochemical reactors in the engineering ...

Polymers with a nitrogen-based linkage resulted in compounds called pyrroles, whereas those made with oxygen produced furans. Pyrroles and furans are both abundant, naturally occurring compounds.

The two components of these blended polymers have differing benefits and challenges when used as potential biodegradable packaging. Polycaprolactone (PCL) allows for better material function, but this ...
