Summary: The electrochemical deposition of rare earth metals at room temperature has gained increasing attention for its energy efficiency advantage over traditional processes. However, the formation of a passivating fluoride layer during electrolyte decomposition is often overlooked, leading to the rapid decay of deposition current and hindering practical application. To address this issue, a fluorine-free electrolyte utilizing borohydride anion was demonstrated, enabling efficient electrodeposition of rare earth metals without passivation effect. Synergetic effects between rare earth borohydride and lithium borohydride were observed, promoting dissociation and improving ionic conductivity and electrochemical performance.

Summary: In this study, rare earth (Gd) and transition metal (Co) co-doped LaFeO3 perovskite and its carbon nanotube (CNT) reinforced nanohybrid were prepared via a wet-chemical and post-ultrasonication method. The doped and reinforced materials were characterized using various physical and electronic techniques, and their effects on morphology, surface area, conductivity, and band structure were investigated. The resulting LGFCO@C catalyst exhibited excellent catalytic capabilities for the mineralization of anionic dye phenol red (PR), attributed to its hybrid composition, optimal band gap, large surface area, and high electronic conductivity. The incorporation of CNTs significantly improved light harvesting and catalytic activity. The stability and reusability of the LGFCO@C catalyst were also evaluated, showing only a minor decrease in activity after multiple reuse cycles. The study suggests that integrating multiple features into a single catalyst holds promise for advancing photocatalysis.

Summary: An optical quantum memory is a device that can store and release photonic quantum information. It is crucial for mitigating channel losses in large-scale quantum networks. Different physical systems such as atomic gases, single atoms in optical cavities, and rare-earth-ion doped solids have been used for realizing optical quantum memories. The focus is now on miniaturization and integration of quantum memories for practical applications in quantum networks, with solid state systems being a favored choice due to their stability and ease of fabrication.

Summary: This study proposes a bioorthogonal approach mediated by extracellular vesicles (EVs) derived from tumors to improve in vivo tumor imaging. By labeling ternary downconversion nanoparticles (DCNPs) with strong near infrared II (NIR-II) luminescence using EVs metabolically engineered with azide groups, remarkable improvement in tumor accumulation was achieved compared to passive targeting. This bioorthogonal labeling significantly increased NIR-II luminescence signals and prolonged retention at tumor sites.

Summary: Rare-earth-doped nanoparticles (RENPs) are promising for biomedical applications, but their interactions with proteins forming a protein corona (PC) can influence their fate in cells. This study focused on investigating the composition of the PC and its impact on cellular uptake for different surface-coated RENPs. Results showed that the stability and composition of the PC varied depending on the surface coating, affecting the internalization of RENPs in cancer cells through endocytic pathways. Understanding these nano-biointeractions is crucial for the future use of RENPs in biomedicine.

Summary: The size and shape of nanoparticles have a significant impact on their photoluminescence quantum yield (PLQY). This study found that the distortion of the crystal lattice in nanoparticles smaller than 20 nm led to an increase in PLQY. Additionally, the shape of nanoparticles within the range of 20-60 nm was found to be particularly relevant for PLQY.

Summary: Upconverting nanoparticles (UCNPs) have great potential for biomedical applications by converting NIR radiation to visible and UV radiation. Coating UCNPs with custom-made hydrophilic polyelectrolytes enhances their emission intensity and photoluminescence lifetime, making them more efficient for cancer cell labeling. Proper polymer coating improves the stability, cellular uptake, and quality of cellular labeling of UCNPs.

Summary: Nanoparticle-assisted laser tissue soldering is an appealing concept in surgical medicine for facilitating wound healing and avoiding sutures. However, the rapid temperature elevation can cause tissue damage. To monitor tissue temperature and achieve satisfactory healing results, we propose a non-invasive and non-contact method using terahertz radiation to visualize the localized photothermal damage.
