Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Preparation of Rare Earth Lu-doped TiO2 Film by Sol-gel Method and Its Photocatalytic Degradation of Methyl Orange Under Natural Light

Medžiagotyra, 2022
TiO2 can effectively degrade organic pollutants under ultraviolet radiation. Due to the large band gap of TiO2, natural light is not suitable for catalysis, which reduces the applicability of TiO2 materials.
