RETRACTED: Mycosynthesis of Hematite (α-Fe₂O₃) Nanoparticles Using <em>Aspergillus niger</em> and Their Antimicrobial and Photocatalytic Activities by Ebrahim Saied, Salem S. Salem, Abdulaziz A. Al-Askar, Fathy M. Elkady, Amr A. Arishi, Amr H. Hashem

“…The structural and optical properties of Hem-NPs were investigated using X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic light scattering (DLS), and UV-visible and Fourier-transform infrared (FTIR) spectroscopies. The results revealed that all of the studied parameters, as well as their interactions, had a significant impact on the crystallite size. …”
