Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties

Macromolecular Rapid Communications, EarlyView.
A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Effect of temperature and strain rate on compressive response of extruded magnesium nano-composite

Journal of Magnesium and Alloys, 2015
The hot deformation behaviour of extruded magnesium-zinc oxide nano composite has been studied using hot compression test. The test was conducted in the temperature range of 250–400 °C and in the strain rate range of 0.01 to 1.5 s−1.The processing map ...

Investigation on hot workability and mechanical properties of.pdf

, 2022
This paper explores the effects of solution treatment on hot workability and mechanical properties of a Ni3Al-based alloy named IC-221M. As-cast IC-221M alloy cracked during the hot working process. Optical and scanning electron microscopy revealed that cracks initiated and propagated through ?+Ni5Zr eutectic phase during hot working.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Care Praxis–Driven STEM Design for Sustainable and Just Communities in Middle School

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Despite the growing interest in incorporating care ethics into STEM education, these topics are rarely integrated into K‐12 standards and pedagogical practice. We explore how care praxis, a political and ethical approach to STEM education, supports students' sense‐making in addressing real‐world problems throughout STEM design, merging social,

Multi‐Vine Disease Prediction in a Field Test Spanning Whole Growth Season at Wine‐Industrial Site (McLaren Vale)

Artificial Intelligence for Engineering, EarlyView.
Overall, the findings provide reliable evidence for block‐level disease early warning, inspection prioritisation, and spray decision‐making, helping to reduce unnecessary inputs, lower environmental burdens, and improve the resilience and sustainability of vineyard production systems.

Who Is a Patriotic Man? Rethinking Hegemonic Masculinity in Modern Iran

Gender &History, EarlyView.
ABSTRACT This article examines the analytical viability of the concept of “hegemonic masculinity” in the historical study of masculinities in early‐twentieth‐century Iran (c.1890–1941). It argues that a radical problematizing of the concepts of hegemony, class, “the West,” and patriotism helps us move beyond the binaries of Western‐Iranian and modern ...

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...
