Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer 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.

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

Polymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

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

Quarterly 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.

Proposing a Framework to Center Justice in Ambitious Science Teaching

Science Education, EarlyView.
ABSTRACT Though educators and researchers have developed shared theory and language for priorities necessary to disrupt the status quo toward more equitable science education, we lack a tool that organizes sets of teaching practices across an instructional unit to support enactment and rehearsal.

Embodied, Enacted, and Multimodal: Exploring Science Teachers’ Metaphors in Authentic Classroom Contexts

Science Education, EarlyView.
ABSTRACT Over the past decades, science education research has extensively examined the role of metaphors in teaching and learning science. However, much of the existing research has focused on verbal manifestations of metaphors, thereby overlooking aspects of metaphors that may occur in non‐verbal form. This study reconceptualises metaphors as dynamic

The Transformational STEM Consciousness Scale: A QuantCrit Measure of a Liberatory STEM Outcome

Science Education, EarlyView.
ABSTRACT Guided by QuantCrit, we introduce and validate the Transformational STEM Consciousness (TSC) scale, which fuses students' motivation to pursue racial and social justice through STEM with a critique of STEM's historic complicity in inequity. Surveying 255 undergraduate and graduate students in 18 justice‐integrated STEM courses across 11 US ...

An Exploration of the Relationships Between Science Identity and Disabled Identities in Undergraduate Science Students

Science Education, EarlyView.
ABSTRACT Science identity is often conceptualized through constructs such as performance, competence, recognition, and interest, with prior research highlighting the roles of race, gender, and cultural background in shaping students' experiences. However, limited scholarship has examined how disability interacts with science identity in postsecondary ...

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

Sleep 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 ...

An Ecological Systems Analysis of University Students' ChatGPT Use in Higher Education

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Educational technology research has largely conceptualised students' ChatGPT adoption through individual‐level cognitive or integrity frameworks, leaving multilevel systemic conditions undertheorised. This study applies Bronfenbrenner's ecological systems theory (EST) to examine how students at a research‐intensive university in Istanbul ...
