Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin

open access: yesJournal of Applied Polymer Science, EarlyView.
The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting Tg,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior Tg of 135°C.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Pelvic breadth and juvenile locomotor energetics: Implications for the obstetrical dilemma hypothesis across human growth in past and present humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

IFAA Recommendations for good practice for the donation and anatomical study of human remains (revised 2026)

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The study of human anatomy is foundational to education and research in the anatomical and health sciences. In 2012, the International Federation of Associations of Anatomists (IFAA) first published Recommendations to promote ethical practice in the acquisition of human remains for this purpose.
