Optimal Method to Realize Quantitative Detection of 1D and 2D Nanoassemblies Based on AIE-Active Bolaamphiphilic Molecules.

Controllable transformation between the bolaamphiphilic molecule assemblies with different morphological nanostructures represents an exciting new direction for materials. However, there are still significant challenges for the quantitative detection and real-time monitoring of a controllable nanoself-assembly process due to insufficient measuring methods. Herein, we propose a new and effective fluorescence technology for realizing quantitative detection of a controllable conversion process of one-dimensional (1D)/two-dimensional (2D) nanoassemblies by introducing AIEgens as the fluorescence signal part.

Estimating the Risk of Women Anemia Associated with Ozone Exposure Across 123 Low- and Middle-Income Countries: A Multicenter Epidemiological Study.

Anemia in women of reproductive age (WRA) presents a pressing global public health issue, particularly in low- and middle-income countries (LMICs). Yet, the potential impact of ozone (O) exposure on anemia remains uncertain. The study included 1,467,887 eligible women from 83 surveys of 45 LMICs between 2004 to 2020.

An Integrated, Portable, and Automatic Digital Detection System for Hepatitis B Virus Using Hybrid Magnetic System.

The rapid, precise, and automated diagnosis of infectious diseases is crucial for effective disease management and control. Herein, the integrated portable and automatic digital detection system (IPADS), a novel diagnostic platform for nucleic acid detection is introduced. The device employs the hybrid magnetic system (HMS), which uses an electromagnet and a movable permanent magnet to modulate the magnetic field and control bead movement, increasing nucleic acid extraction efficiency to over 80%, while simplifying the traditional labor-intensive process and enabling quick, low-risk sample processing.

Exploring micro(nano)plastics toxicity from an environmental management perspective: Zebrafish as a vital bridge for assessing potential human health risks.

The pollution stemming from the unwarranted utilization and inadequate disposal of plastic products is undergoing rapid escalation. The problem of micro(nano)plastics (MNPs) pollution has recently garnered significant attention, and the issue of human exposure to MNPs cannot be disregarded. However, the present state of research concerning human exposure to MNPs remains in its early stages.

Optimization design and experiment of cam-elliptical gear combined vegetables curved surface labeling mechanism.

To address the problems of the labeling curved surfaces vegetable with long label, such as the label wrinkled and the easy detachment, a cam-elliptical gear combined labeling mechanism with an improved hypocycloid trajectory is proposed. Provide the process of the mechanism, and establish a kinematic model of the mechanism. In order to improve the motion performances of the cam-elliptical gear combined labeling mechanism and avoid labels damage, the NSGA-II algorithm is used to optimize the parameters of the mechanism, resulting in 80 sets of Pareto solutions.
