Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

open access: yesCarbon and Hydrogen, EarlyView.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

Maize Kernel Composition and Morphology Influences Pericarp Retention During Nixtamalization

open access: yesCereal Chemistry, EarlyView.
Abstract Background and Objectives Pericarp retention during nixtamalization directly influences masa quality, affecting texture, machinability, and nutritional content of staple foods such as tortillas and chips. Despite its industrial relevance, the underlying kernel traits that govern pericarp retention remain poorly characterized.
