Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

open access: yesFood Frontiers, EarlyView.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...
