Challenges of midwifery staff at Tehran hospitals: A qualitative study from the midwifery managers perspective.

Aim: This study aimed to investigate the challenges faced by midwifery staff working in hospitals from midwifery manager's perspectives and provide suggestions to solve them.

Design: Descriptive qualitative study.

Methods: The study was conducted in Tehran in 2021.

α-FeO/graphene oxide powder and thin film nanocomposites as peculiar photocatalysts for dye removal from wastewater.

In this study, hematite graphene oxide (αFeO-GO) powder nanocomposites and thin-film hematite graphene oxide (αFeO-GO) were synthesized for application in the removal of Rhodamine B (RhB) from textile wastewater. αFeO-GO nanomaterials were placed onto the FTO substrate to form a thin layer of nanocomposites. Different analysis including XRD, FTIR, Raman spectra, XPS, and FESEM were done to analyze the morphology, structure, and properties of the synthesized composites as well as the chemical interactions of αFeO with GO.
