Multi-metal MOF-on-MOF metal-organic gel-based visual sensing platform for ultrasensitive detection of chlortetracycline and D-penicillamine.

The widespread presence of antibiotic residues in the environment and food represents a significant threat to human health. In this study, a novel MOF-on-MOF (FCZE) gel with excellent peroxidase activity and strong fluorescence properties successfully synthesized by using Polyvinyl pyrrolidone (PVP) as a cross-linker and H₄BTEC as a ligand. Based on the energy transfer from the FCZE ligand to Eu luminescence, an ultrasensitive fluorescence method was developed for the detection of chlortetracycline (CTC), achieving a limit of detection (LOD) as low as 0.

Association between triglyceride glucose-body mass index and depression among US adults: A cross-sectional study.

Objectives: The triglyceride glucose-body mass index (TyG-BMI) is a well-established surrogate marker for insulin resistance. While an association between insulin resistance and depression has been identified, that between TyG-BMI and depression remains unclear. Therefore, we used data from the National Health and Nutrition Examination Survey (NHANES) database to investigate this.

Review of Acoustic Agglomeration Technology Research.

Acoustic agglomeration is employed as a precursor technique that modifies the sound field of fine particles to increase their size, thereby facilitating more efficient emission control. This paper reviews progress in the field of acoustic agglomeration technology, clarifies the mechanisms at play within the acoustic agglomeration process, and outlines its applicability in both gas-liquid and gas-solid phases. Furthermore, it analyzes the factors impacting the efficacy of acoustic agglomeration, summarizes the numerical simulation research of acoustic agglomeration, and proposes directions for technological enhancement.
