POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Yucatan Current variability through the Cozumel and Yucatan channels

open access: yesCiencias Marinas, 2011
A comparison based on eight months of simultaneous observations of the flow variability in the Yucatan and Cozumel channels shows that the portion of the Yucatan Current that crosses through Cozumel Channel is best correlated with the flow near the ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

open access: yesAdvanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Structural pattern of the Todos Santos Coastal Plain, based on geophysical data

open access: yesCiencias Marinas, 2004
A set of gravity and magnetic data taken within the Todos Santos Coastal Plain between 1962 and 2000 from land, sea and air is used to integrate the structural framework and tectonic model of this area. The present work collected all the available data,

Development of interactive MRI‐based 3D visualization tools for neuroanatomy education in Latin America

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Nutrient input from the Colorado River to the northern Gulf of California is not required to maintain a productive pelagic ecosystem

open access: yesCiencias Marinas, 2015
The high phytoplankton production (PP) of the northern Gulf of California (NGC) supports a rich biodiversity and fisheries with high yields. The NGC is the habitat of the vaquita (Phocoena sinus), the cetacean most at risk of extinction in the world ...
