来源：ACS PublicationsWe investigated the photoelectrical conversion properties of various rare-earth ferrites (REFeO3) as photoelectrochemical capacitor cathode materials. Among electrodes of LaFeO3 with different crystallinities, the electrode using it prepared by solid-state synthesis showed the highest photovoltage. Its highest crystallinity probably suppressed the electron–hole recombination to promote the hole accumulation. In various REFeO3 (LaFeO3, NdFeO3, GdFeO3, and ErFeO3), electrical conductivity and photovoltage were increased with increasing rare-earth ion size. We consider that hol...

来源：ACS PublicationsWe describe the osteogenic potential and hemocompatibility of rare-earth-doped hydroxyapatite in a murine preosteoblastic (MC3T3-E1) cell line, aiming to assess the osteoblast differentiation effect of ytterbium-, terbium-, cerium-, and europium-doped hydroxyapatite through alkaline phosphatase activity and the expression levels of osteogenic marker genes, including Runx2, ALP, OPN, and BMP2. Our findings reveal various levels of enhancement in early osteogenic activity across the four dopants. Among the dopants tested, europium- and ytterbium-doped hydroxyapatites produce t...

来源：ACS PublicationsRare earths (RE) are crucial strategic resources and have demonstrated remarkable efficacy in material modification. However, there is a wide variety of RE elements, and the mechanism for regulating electronic structure is unclear, which limits their accurate selection and efficient utilization. The RE tetrad effect divides RE elements into four groups, with the boundaries set at the points where the 4f electrons are filled to 1/4, 1/2, and 3/4. Herein, we present a systematic strategy for regulating the electronic structure of Co-based spinel compounds via it. Research resu...

来源：ACS PublicationsTo enhance the upconversion luminescence (UCL) of small-sized nanoparticles, core–shell nanostructures are employed to effectively isolate emitting ions from surface quenchers. However, the synthesis of such structures is frequently compromised by cation intermixing, a result of core dissolution during shell growth. This unintended ion diffusion undermines the passivation function of the inert shell, as emitting ions relocated near surface defects contribute to nonradiative energy loss, thus diminishing luminescence enhancement. This detrimental effect is especially severe f...
