    Biosorption of Lanthanides from Aqueous Solutions Using Pretreated Buccinum tenuissimum Shell Biomass by Yusuke Koto, Naoki Kano, Yudan Wang, Nobuo Sakamoto, Hiroshi Imaizumi

    Published 2010-01-01
    “…Consequently, the following matters have been mainly clarified. (1) The crystal structure of the shell biomass was transformed from aragonite (CaCO3) into calcite (CaCO3) phase by heat-treatment (480∘C, 6 hours); then mainly transformed into calcium oxide (CaO) by heat-treatment (950∘C, 6 hours), and calcium hydroxide (Ca(OH)2) by heat-treatment (950∘C, 6 hours) and adding water. (2) The shell biomass showed excellent sorption capacity for lanthanides. (3) Adsorption isotherms using the shell biomass can be described by Langmuir and Freundlich isotherms satisfactorily for lanthanides except “heat-treatment (950∘C, 6 hours) sample”. (4) Shell biomass (usually treated as waste material) can be an efficient sorbent for lanthanides in future.…”

    Suppressing surface segregation by introducing lanthanides to enhance high-temperature oxygen evolution reaction activity and durability by Jingwei Li, Zichao Wu, Yuxiang Shen, Yuefeng Song, Houfu Lv, Xiaomin Zhang, Guoxiong Wang

    Published 2025-01-01
    “…A critical challenge lies in alleviating surface segregation and preserving the high OER performance of BSCF anodes. Herein, lanthanides are introduced to substitute the Ba in BSCF, labeled as Ln _0.5 Sr _0.5 Co _0.8 Fe _0.2 O _3− _δ (LnSCF, Ln = La, Pr, Nd, Sm), to regulate its stability and performance. …”
