analysis of heavy metals and halogenated compounds in reclaimed water using novel electrospray ionization combined with plasma ionization linear ion trap mass spectrometry.

Water scarcity is a global concern that needs addressing through alternative sources. One of the approaches is the use of reclaimed water for irrigation. However, the presence of halogenated compounds and heavy metals in reclaimed water poses significant food safety threats.

Band Gap Engineering of Binary and Cobalt-Doped PbS Thin Films Integrated by SILAR Method for Optoelectronic Potentials.

Thin films of PbS, both undoped and cobalt-doped (Co-PbS), were produced on glass substrates using the straightforward and controllable approach of sequential ionic layer adsorption and reaction (SILAR). The reactive substances employed to deposit the PbS thin films were lead nitrate (Pb(NO)), cobalt nitrate (Co(NO₃)₂(H₂O)₆), sodium thiosulphate (NaSO) and HO for different dipping concentrations of lead and cobalt. The films were adherent to the substrate and were compact, and crack-free with a shiny silver color.

Health Facility Capacity and Health-care Worker Knowledge, Attitudes, and Practices of Hepatitis B Vaccine Birth-dose and Maternal Tetanus-Diphtheria Vaccine Administration in Nigeria: A Baseline Assessment.

Background: Hepatitis B virus (HBV) and neonatal tetanus infections remain endemic in Nigeria despite the availability of safe, effective vaccines. We aimed to determine health facilities' capacity for hepatitis B vaccine birth dose (HepB-BD) and maternal tetanus-diphtheria (Td) vaccination and to assess knowledge, attitudes, and practices of HepB-BD and maternal Td vaccine administration among health facility staff in Nigeria.

Materials And Methods: This was a cross-sectional study assessing public primary and secondary health facilities in Adamawa and Enugu States.
