Contra‐Diffusion Engineering of Single‐Atom Catalytic Interlayers Enables Reversible Sulfur Redox Chemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
A contra‐diffusion strategy is introduced to grow uniformly distributed Co–Nx single‐atom catalysts (CoSAs) within a carbonized aramid nanofiber (CANF) interlayer. The resulting CD‐CANF enables efficient polysulfide regulation, low metal loading, and exceptional long‐term cycling stability in lithium–sulfur batteries. ABSTRACT Achieving durable lithium–

Natural Antioxidants as Thermal Stabilizers in Post‐Consumer Polypropylene

open access: yesJournal of Applied Polymer Science, EarlyView.
A synergistic antioxidant system combining two natural antioxidants, quercetin and tocopherol, enhances the thermo‐oxidative stability of recycled polypropylene. The approach addresses key barriers to the utilization of recycled polymers, offering a sustainable pathway to improve material performance and supporting the broader adoption of recycled ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Understanding the spacing of placodes in the eye: A comparative study across age and species

open access: yesThe Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.
