The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Escribir en comunidad: Construcción de relaciones y responsabilidad en la producción de conocimiento

American Anthropologist, Volume 127, Issue 3, Page 447-465, September 2025.
ABSTRACT As anthropology reckons with its past, present, and future, anthropologists increasingly seek to challenge inequities within the discipline and academia more broadly. Anthropology, regardless of subdiscipline, is a social endeavor. Yet research often remains an isolating (though not necessarily solitary) process, even within research teams and

Superstability of micrometre jets surrounded by a polymeric shell

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1261-1268, August 2025.
Superstable micrometre compound jets have been produced for serial femtosecond X‐ray crystallography.We have produced superstable compound liquid microjets with a 3D‐printed coaxial flow‐focusing injector. The aqueous jet core is surrounded by a shell, a few hundred nanometres in thickness, of a low‐concentration aqueous solution of a low‐molecular ...

High‐Quality Epitaxial Five‐Layer Aurivillius Films with In‐Plane Ferroelectricity for Electrocaloric Cooling

Advanced Electronic Materials, Volume 11, Issue 11, July 2025.
High‐quality epitaxial five‐layer Sr2Bi4Ti5O18Aurivillius films are grown on SrTiO3 by pulsed laser deposition. The electrocaloric effect derived from measurements of the in‐plane ferroelectric polarization reveals a maximum temperature change of ΔT ∼ 0.95 °C under an electric field of 150 kV cm⁻¹ at 135 °C.
