Linking Process‐Induced Degradation to Mechanical Property Deterioration in Flax Fiber–Reinforced Bio‐Polymer Matrix Composites

open access: yesPolymer Composites, EarlyView.
Effect of processing‐induced thermal degradation on the mechanical performance of thermoplastic flax fiber composites. ABSTRACT The drawback of biobased polymer matrix composites (PMCs) is their limited temperature stability, resulting from degradation, which restricts their processability in established composite manufacturing processes requiring ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Tourist sightings improve the precision of camera trap‐derived density estimates using spatial capture‐recapture models

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine tourist‐contributed images with camera trap‐based monitoring data to estimate leopard (Panthera pardus) population densities using multi‐session spatial capture–recapture models. We show that incorporating tourist observations improves precision and yields an overall density estimate of 7.02 leopards per 100 km2, while ...

Study of the Performance and Smoke Density When Gasoline–Diesel Blends Are Used as Fuel of a Diesel Engine

open access: yesJournal of Engineering
The world is currently facing a serious environmental crisis, partly driven by the pollutant emissions from diesel engines. Although these engines are known for their efficiency, their emission levels are highly dependent on fuel quality.

“There Are Places Full of Beauty”: Desettling High School Students' Scientific Writing

open access: yesScience Education, EarlyView.
ABSTRACT This study contributes to desettling and expanding expectations about the forms of scientific language that belong in students' scientific writing. The primary empirical focus is the analysis of 52 high school student abstracts articulating community‐based investigations, submitted as part of their participation in a student conference in a ...

A Method for Assessing the Risks to Sustainability Posed by Process Operations

open access: yesSustainable Development, EarlyView.
ABSTRACT We present a framework for assessing the risks to sustainability posed by any given set of processes. The objective is to improve sustainability by enabling better decision‐making in policy and business contexts. The framework can be applied to any system of processes where available information supports discovery and quantification of ...
