Impact of Waste‐Derived Slate Dust on Structural, Thermal, and Thermomechanical Behavior of Recycled Poly(Ethylene Terephthalate)

open access: yesPolymer Composites, EarlyView.
This study investigates the use of waste slate dust as a filler in recycled PET. Incorporating up to 20 wt% slate dust caused no filler‐induced molecular degradation, increased the crystallization temperature, thermal conductivity, and storage modulus. ABSTRACT Recycled polyethylene terephthalate (rPET) is widely considered a sustainable alternative to

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...

Advancing Sustainable Development Through Resource Efficiency: Institutional Asymmetries and Firm Capabilities in European Agri‐Food SMEs

open access: yesSustainable Development, EarlyView.
ABSTRACT Resource efficiency has become a priority for the European agri‐food sector, yet adoption remains uneven across countries and firms. This study examines how European agri‐food small and medium‐sized enterprises (SMEs) adopt resource efficiency practices.

Beyond sleep‐specific bias: Eye‐tracking observations of general negative attentional biases linked to insomnia

open access: yesSleep Research, EarlyView.
Abstract Although attentional bias toward sleep‐related stimuli is well documented in insomnia and is regarded as a cognitive outcome arising after the disorder's onset, it remains unclear whether insomnia also involves a general negative attentional bias toward nonsleep negative stimuli, a transdiagnostic vulnerability for psychiatric disorders ...
