Polyhydroxyalkanoates (PHAs) represent a promising class of biodegradable polyesters synthesized by various microorganisms as energy storage compounds. Their versatility and environmental friendliness make them potential candidates for replacing conventional plastics across numerous applications. However, challenges such as limited mechanical properties, high production costs, and thermal instability have hindered their widespread adoption.

Background: We synthesised the current evidence in coverage and quality of delivery care, change in neonatal mortality (NMR), and causes of neonatal death in the private sector deliveries in the Indian state of Bihar from 2011 to 2021.

Methods: Women aged 15-49 years with livebirths were interviewed in three household surveys involving state-representative samples in 2011, 2016 and 2020-2021 designed to document the coverage of maternal and newborn health services and change in NMR over time. Verbal autopsy interviews were used to assign the cause of neonatal death.

Zirconium dioxide nanoparticles (ZrO NPs) have gained significant attention due to their excellent bioavailability, low toxicity, and diverse applications in the medical and industrial fields. In this study, ZrO NPs were synthesized using zirconyl oxychloride and the aqueous leaf extract of as a stabilizing agent. Analytical techniques, including various spectroscopy methods and electron microscopy, confirmed the formation of aggregated spherical ZrO NPs, ranging from 15 to 30 nm in size, with mixed-phase structure composed of tetragonal and monoclinic structures.
