Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Significantly Different Prevalences of Contact Allergy to Hydroperoxides of Linalool and Limonene When Patch Testing With Different Patch Test Chambers

Contact Dermatitis, EarlyView.
Finn Chamber AQUA (FCA) detects significantly higher contact allergy prevalences to linalool hydroperoxides (7.0% vs. 5.1% FC) and limonene hydroperoxides (7.8% vs. 3.0% FC, 3.8% IQ) than Finn Chamber (FC) or IQ Ultra (IQ) in 629 dermatitis patients; chamber choice is therefore crucial for diagnostics.

Comparison of a 3D‐printed skin model with established methods for teaching punch biopsy with suturing

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Realistic and accessible models are essential for training physicians in clinical procedures. This study investigated whether a cost‐effective 3D‐printed skin model is superior to fruit and foam models for teaching skin biopsies. Patients and Methods The study (10/2023‐02/2025) involved 148 medical students who compared the 3D skin ...

Vergleich eines 3D‐gedruckten Hautmodells mit etablierten Methoden zur Lehre der Stanzbiopsie mit Nahtversorgung

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Zusammenfassung Hintergrund Realistische Trainingsmodelle sind essenziell, um Ärztinnen und Ärzte in klinischen Prozeduren zu schulen. In dieser Studie wurde untersucht, ob ein kostengünstiges, selbst generiertes 3D‐gedrucktes Hautmodell Früchten und Schaumstoffmodellen beim Erlernen von Hautstanzen überlegen ist.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.
