Prevention of Mother-to-Child HIV Transmission Service Utilization among Pregnant Women in Northeast Ethiopia: A Cross-Sectional Survey.

Background: Targeting pregnant women attending antenatal care clinics provides a unique opportunity for implementing the Prevention of Mother-to-Child Transmission (PMTCT) programs against human immunodeficiency virus (HIV) infection of newborn babies. The objective of this study was to assess the PMTCT service utilization rate and to characterize its reasons among pregnant women attending antenatal care clinics at selected public health facilities in Debre Berhan Town, Northern Ethiopia.

Methods: A facility-based cross-sectional survey was conducted among 355 pregnant women from May 1 to June 15, 2019.

Photocatalytic degradation of methylene blue dye by zinc oxide nanoparticles obtained from precipitation and sol-gel methods.

Zinc oxide (ZnO) nanoparticles were synthesized by precipitation and sol-gel methods. The aim of this study was to understand how different synthetic methods can affect the photocatalytic activity of ZnO nanoparticles. As-synthesized ZnO nanoparticles were characterized by X-ray diffraction (XRD) and UV-Visible spectroscopic techniques.
