Towards of multi-source data fusion framework of geo-referenced and non-georeferenced data: prospects for use in surface water bodies

Geocarto International, 2023
This paper proposes an approach of fusion geo-referenced and non-georeferenced data. These data can be acquired by a) unmanned surface vehicles (USVs), b) unmanned aerial vehicles (UAVs), c) airborne and submersible optical sensors, d) acoustic sensors ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

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

Ciencias 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,

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Influence of mother plant age on the in vitro propagation of Agave cupreata Trel. & A. Berger via organogenesis

Discover Plants
Agave cupreata Trel. & A. Berger is an endemic species from southern Mexico with cultural and economic value due to its use in mezcal production. The increasing global demand for mezcal has led to intense overexploitation, resulting in a marked decline ...

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

Advanced 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.

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

Ciencias 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 ...

Weeds of commercial crops in Colima, Mexico

Revista Mexicana de Biodiversidad, 2021
Weeds are plants adapted to habitats modified by people and that often interfere with different human activities. These plants constitute an economically and ecologically relevant group because of their implications for agriculture. Because the agrestal
