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

Viscosidad de un fluido

Ingenio y Conciencia Boletín Científico de la Escuela Superior Ciudad Sahagún, 2022
En la presente práctica de laboratorio se analiza el comportamiento dinámico de un objeto sumergido en un fluido viscoso que desciende a través de la consideración de la fuerza gravitacional, la fuerza de empuje y la fuerza de arrastre, para estimar la viscosidad de un fluido.

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.
