Population and Transcriptomic Changes of the Tropical Fish Parasite Caligus confusus (Copepoda: Caligidae) with Seasonal Variations in Sea Temperature
(MDPI, 2023)Fish–parasite systems could be subject to two scenarios under climate change: (i) increased water temperature might enhance parasite metabolism, allowing the parasite to spread rapidly; (ii) parasitism could decrease if ... -
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 ... -
Metal decorated carbon nanotube aerogels from sodium polyacrylate crosslinking by divalent ions
(Elsevier, 2023)In this work sodium polyacrylate functionalized carbon nanotube aerogels were prepared from aqueous medium by simple ionic cross-linking using copper nitrate and calcium chloride as cation sources to obtain self-standing ... -
