There has been an increase in demand for nanocomposite, which has resulted in large-scale manufacturers employing high-energy processes and harmful solvents. Because of this, the need for environmentally benign "green" synthesis processes has grown. Other methods for making nanocomposite include using plants and plant products, bacteria, fungi, yeast, and algae. Green synthesis has minimal toxicity and is safe for human health and the environment compared to other processes, making it the ideal option for creating nanocomposite materials. This work reveals an environmentally friendly synthesis method for magnetic nanocomposites. In particular, they were using an aqueous extract of Artemisia to obtain ZnO/Fe3O4 using cold plasma technology. The magnetic nanocomposite was prepared with different concentrations (0.01, 0.02, and 0.03) of M and (2:8) of the aqueous extract. The structural properties were studied using X-ray diffraction, where the crystal size ranged from 30 to 40 nm, while the surface morphology was studied through the field emission scanning electron microscope, and it was found that the shape of the particles is semi-spherical and within a particle size range of 30 to 60 nm. "Green" magnetic nanocomposites showed low toxicity and high biocompatibility, allowing their application in biomedicine, where magnetic nanocomposites were employed as anti-agents for E. coli and S. aureus using the agar diffusion method. Its high effect on bacterial inhibition was noted when the concentration was increased, as the diameter of inhibition ranged (11-22) mm for E. coli and (15-24) mm for Staphylococcus aureus.

Zinc selenide (ZnSe) nanostructure’s optical and structural characteristics were investigated in this study. Pulse laser deposition of thin films on glass substrates was achieved using an Nd:YAG laser (wavelength 1064 nm) at different laser powers (100, 200, 300, 400 and 500 mJ) with fixed pulses 100 pulses, repetition rate 6 Hz and distance 10 cm between laser and the substrate with a thickness of films 200 nm. An atomic force microscope (AFM) and X-ray diffraction method were used to research the impact of altering the laser intensity on the structural characteristics. A branched (100) polycrystalline type and a plane (111) and branched (100) polycrystalline type are prevalent (002). In addition, AFM measurements further revealed that the smallest granular size achieved at high laser power was 48.40 nm at 100 mJ. The findings showed that it is possible to construct nanostructures with medium grain sizes of alumina (72.99 nm). The study of the relationship between laser energy and nanostructure optical characteristics was explored and it was discovered that the transitions had a specific range of 2.83–3.10 eV.
