Summary: In this study, a novel PbO2 electrode modified with rare earth elements (La, Ce, Gd and Er) doping was prepared by electrodeposition. The micro-morphology, crystal structure, and electrochemical properties of the modified electrode were characterized. The results showed that rare earth elements doping significantly improved the oxidation ability of the PbO2 electrode by reducing grain size, increasing oxygen evolution potential, enlarging electrochemical active surface area, and enhancing center dot OH formation ability.

Summary: The study introduces a facile strategy for fabricating Nd3+-doped rare-earth core-shell nanoparticles (Nd-RENPs) with strong emission in the near-infrared-II (NIR-II) window. These Nd-RENPs can be quickly eliminated from the hepatobiliary pathway, reducing the potential risk of long-term retention in the reticuloendothelial system (RES). Additionally, the Nd-RENPs are successfully utilized for NIR-II in vivo imaging and magnetic resonance imaging (MRI) contrast agents, enabling precise detection of breast cancer.

Summary: In this study, it was found that using Partial Least Squares Regression (PLSR) models to link laboratory sample reflectance to mineral/geochemical properties can be employed for quantitative predictions of bulk LREE and HREE concentrations. However, limitations include the need to exclude samples with high hematite content and low REE concentrations, as well as the significant impact of sample mineralogy on the predictions. Further research is needed to validate and refine prediction models for diverse lithological carbonatite sites.

Summary: To promote Ti scrap recycling, new technologies are needed to efficiently remove oxygen impurities. However, direct removal of oxygen from solid Ti is extremely difficult and there are currently no effective deoxidation methods for industrial use. This study experimentally verified a new deoxidation technique for Ti using the vapor of high-vapor-pressure rare earth metals such as Sm, Eu, Tm, and Yb. The results showed that Eu did not decrease oxygen concentration below 1000 mass ppm in Ti samples, while the vapor of Sm, Tm, and Yb decreased oxygen concentration through oxide formation reactions. Tm vapor was particularly effective in deoxidizing Ti at or below the oxygen concentration of Ti sponge produced by the Kroll process (3500 mass ppm O).

Summary: A new series of soda-lime glass doped with Nd and Eu2O3 was densified in a multi-anvil press up to 21 GPa, showing a maximum densification saturation of 3.55 +/- 0.14%. The evolution of Nd3+ transition was found to be the most sensitive calibration, while Brillouin spectroscopy exhibited a divergent behavior. Results suggest better hydrostatic conditions in this study may have contributed to the differences in densification curves reported previously.

Summary: A multi-channel lanthanide nanocomposite was used to achieve tailored synergistic treatment of multiple subcutaneous orthotopic tumors under non-uniform whole-body infrared irradiation prescription. The nanocomposite reduces intratumoral glutathione by simultaneously activating the fluorescence and photothermal channels, enabling customized prescriptions to be made based on individual information provided by fluorescence. With an accessional therapeutic laser system, customized synergistic treatment of subcutaneous orthotopic cancer cases with multiple tumors is possible with both high efficacy and minimized side effects.

Summary: This study reveals that Cs3Bi2Br9 in the Cs3Bi2Br9/CdS heterojunction not only participates in light-driven processes, but also plays a significant role in the activation and conversion of key intermediates during C(sp3)-H bond transformation. Moreover, various aromatic hydrocarbons can be effectively photocatalytically converted to corresponding aldehydes/ketones as major products. This work highlights the importance of surface catalysis mechanisms in photocatalysis for both halide perovskites and other semiconductors.
