Patterns of Richness and Endemism in the Gypsicolous Flora of Mexico
(MDPI, 2023)Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their flora has been poorly studied. ... -
RecruitNet: A global database of plant recruitment networks
(Wiley, 2023)Plant recruitment interactions (i.e., what recruits under what) shape the composition, diversity, and structure of plant communities. Despite the huge body of knowledge on the mechanisms underlying recruitment interactions ... -
The Effect of a Yb Co-Dopant on the Blue Upconversion and Thermoluminescent Emission of SrLaAlO4:Yb3+,Tm3+ Phosphors
(MDPI, 2023)In this study, we described the structural, morphological, optical, photoluminescence, and thermoluminescence properties of SrLaAlO4:Tm3+,Yb3+ (SLAO:Tm,Yb) blue-emitting phosphors made by combustion synthesis and a ... -
Exploring the crystal structure and properties of ytterbium orthoantimonate under high pressure
(Royal Society of Chemistry, 2023)The crystal structure of YbSbO4 was determined from powder X-ray diffraction data using the Rietveld method. YbSbO4 is found to be monoclinic and isostructural to ?-PrSbO4. We have also tested the influence of pressure on ... -
One-Pot Synthesis of Iron-Modified Zeolite X and Characterization of the Obtained Materials
(MDPI, 2023)Iron inclusion in the composition of the zeolite crystal structure endows it with new and useful properties. However, direct synthesis involving Fe, frequently creates unfavorable conditions that hinder the crystallization ... -
Influence of the Valence of Iron on the NO Reduction by CO over Cu-Fe-Mordenite
(MDPI, 2023)A comprehensive study of the catalytic properties of the copper-iron binary system supported on mordenite, depending on the iron valence—CuFe2MOR and CuFe3MOR—was carried out, and redox ability has been considered as a ... -
Are nurse plants useful for facilitating the reintroduction of mid- and late successional tree species in tropical montane cloud forests?
(Sociedad Botánica de México, 2023)Background: In Mexico, where 50 % of the original Tropical montane cloud forest (TMCF) has been lost due to human activities, the restoration of these forests is essential. Questions and/or hypotheses: (1) Liquidambar ... -
Metal decorated carbon nanotube aerogels from sodium polyacrylate crosslinking by divalent ions
