Summary: Lithium, an important resource, is abundant in Salt Lake, but the high Mg2+/Li+ ratio is the main obstacle to its extraction. Researchers have successfully constructed a positively-charged nanofiltration membrane by incorporating polyethyleneimine (PEI) and layered double hydroxide (LDH) nanosheets on hydrolyzed polyacrylonitrile ultrafiltration membrane. The membrane, crosslinked with glutaraldehyde (GA), exhibited enhanced separation performance for Mg2+/Li+ in an aqueous solution, with a separation factor (SMg2+/Li+) of 18.7 when the Mg2+/Li+ ratio was 10. This membrane showed potential for Mg2+/Li+ separation with its maintained performance for 100 hours.

Summary: This work presents the use of potato starch films embedded with a cyanidin-rich onion extract as a food quality sensor. The extract's cyanidin reacts to pH changes caused by food spoilage, allowing it to replace synthetic pigments for monitoring food freshness. The extract is stabilized by being anchored on the surface of a filler made of halloysite nanotubes coated with layered double hydroxide nanocrystals. The filler, synthesized through a sustainable and solvent-free method, not only stabilizes the extract but also serves as a carrier for active species to extend the product's shelf-life.

Summary: Fluorescent lateral flow immunoassay (FLFIA) is widely used for its affordability and quick detection. In this study, dendritic mesoporous silica nanoparticles (DMSNs) were utilized as carriers to synthesize carbon dots (CD560) for FLFIA. By loading CD560 on DMSNs through the Si-O bond, a new type of fluorescence signal, DMSNs@CD560, was created, which improved the sensitivity of FLFIA. The DMSNs@CD560-FLFIA achieved high sensitivity detection of ovarian cancer biomarkers CA125 and HE4, providing a new method for early diagnosis of ovarian cancer.

Summary: This study introduces a novel approach to address the challenges of lower light absorption and faster carrier recombination in photocatalysis by anchoring cadmium sulfide quantum dots (CdS QDs) on inverse opal (IO)-TiO2. The IO-TiO2 structure enhances light absorption by reflecting light in the stop band, while the regulated size of CdS quantum dots promotes carrier transfer and synergistic-amplified photocatalysis. The hierarchical Z-scheme heterojunction exhibits significantly improved photodegradation performance compared to CdS QDs and IO-TiO2 alone.
