“…(i) When Ag-TiO 2 /ZIF-8 is added to a solution containing bacteria, it can release Ag + and Zn 2+ with low toxicity and biological antibacterial activity, these metal ions can come into direct contact with the bacteria and bind to component proteins in cell walls and membranes, denaturing and inactivating the component proteins ( Chen et al, 2023 ; Wang et al, 2023 ). This causes the outer layer to lose its protection and the bacteria burst and die ( Mariappan et al, 2022 ; Sun et al, 2023 ).…”

In recent years, massive bacterial infections have led to human illness and death, reminding us of the urgent need to develop effective and long-lasting antimicrobial materials. In this paper, Ag-TiO2/ZIF-8 with good environmental friendliness and biological antibacterial activity was prepared by solvothermal method. The structure and morphology of the synthesized materials were characterized by XRD, FT-IR, SEM-EDS, TEM, XPS, and BET. To investigate the antibacterial activity of the synthesized samples, Escherichia coli and Bacillus subtilis were used as target bacteria for experimental studies of zone of inhibition, bacterial growth curves, minimum bactericidal concentration and antibacterial durability. The results demonstrated that 20 wt.%Ag-TiO2/ZIF-8 had the best bacteriostatic effect on E. coli and B. subtilis under dark and UV conditions compared to TiO2 and ZIF-8. Under the same conditions, the diameter of the inhibition circle of 20 wt% Ag-TiO2/ZIF-8 is 8.5–11.5 mm larger than that of its constituent material 4 wt% Ag-TiO2, with more obvious antibacterial effect and better antibacterial performance. It is also proposed that the excellent antibacterial activity of Ag-TiO2/ZIF-8 is due to the synergistic effect of Ag-TiO2 and ZIF-8 under UV light. In addition, the prepared material has good stability and durability with effective antimicrobial activity for more than 5 months.

“…However, long-term operation of wearable sensors often results in bacterial proliferation at the interface between the sensor and the skin, which reduces the accuracy of sensors and poses a risk to human health. Usually, antibacterial properties can be achieved by incorporating metallic materials such as Au, Ag, Cu, Zn, and Ga into the matrix material. − Among them, Au and Ag exhibit the strongest antibacterial performance but are expensive. Zn possesses a relatively weaker antibacterial effect, while Ga and Cu demonstrate stronger antibacterial properties against E.…”

“…Acidic precipitation mobilizes aluminium from natural sources, and direct anthropogenic releases of aluminium compounds associated with industrial processes occur mainly in the air. Certain uses lead to the presence of aluminium in drinking water and foodstuffs, and many researchers are keen to study the influences of aluminium oxide such as Chen [7] studied the antibacterial anodic aluminium copper coatings on aluminium alloys which helps in the preparation of materials long-term antibacterial performances. The microchannel system used by Liu et al, [8] to study the strong interaction between Ru/defects-rich aluminium oxide which boosts the photothermal methanation of carbon dioxide.…”

This research article, explores the influence of an inclined magnetic field on the fluid flow over a permeable stretching/shrinking surface with heat transfer. The study use water as a conventional base fluid, with graphene oxide (GO) and Aluminum oxide (Al2O3) nanoparticles submerged to create a nanofluid, the system of governing nonlinear partial differential equations converted into ordinary differential equations via suitable similarity conversions. This allow for the unique solution for stretching sheet/shrinking sheets to be obtained, along with the corresponding temperature solution in terms of the hypergeometric function, several parameters are included in the investigation and their contribution is graphically explained to examine physical characteristics such as radiation, inclined magnetic field, solution domain, volume fraction parameter, and temperature jump. Increasing the volume fraction and thermal radiation increases the thermal boundary layer, increasing the magnetic field parameter and inverse Darcy number increases the temperature and decays the velocity profile. The present work has many useful applications in engineering, biological and physical sciences, as well as in cleaning engine lubricants and thrust-bearing technologies.
