Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...

Crystalline and Microstructural Properties of Cd1−x−yMnxCryTe Semiconductor System (x = 0.33 and 0.05 ≤ y ≤ 0.15)

physica status solidi (a), Volume 223, Issue 3, 6 February 2026.
Cd1−x−yMnxCry (x = 0.33, 0.05 ≤ y ≤ 0.15) quaternary semiconductors were synthesized by direct fusion and characterized by XRD/Rietveld refinement and SEM. All compositions crystallize in the zinc blende structure, exhibiting a systematic lattice contraction with increasing Cr content, evidencing partial Cd substitution, accompanied by marked ...

Trophic Ecology of Loggerhead Turtles (Caretta caretta) in Southern Brazil: Insights From Stable Isotopes

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the trophic ecology of loggerhead turtles recorded stranded along the Paraná coast in southern Brazil. Carbon and nitrogen stable isotopes were analysed in muscle tissues from 20 loggerhead turtles and in 69 specimens representing 12 prey species (molluscs, crustaceans and teleost fishes).

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

The Anatomical Record, Volume 309, Issue 2, Page 293-313, February 2026.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...
