DFT Insight Into Physical Properties of Halide Ions Replacements in Oxo‐Selenate Halide Compounds for Photovoltaic Application

open access: yesEnergy Science &Engineering, EarlyView.
Using density functional theory (CASTEP, GGA–PBE), the structural, electronic, optical, and mechanical properties of YSeO₃X (X = F, Cl, Br, and I) compounds are systematically investigated. The materials have exhibited structural stability, tunable band gaps, strong optical absorption, anisotropic ductile behavior, and promising potential for ...

Solid Biofuel Usage and Households' Behavior Toward Energy Choice in Northwest Ethiopia

open access: yesEnergy Science &Engineering, EarlyView.
This study analyzed household energy choice behavior in northwest Ethiopia using an integrated energy stacking and decision‐making framework. Evidence shows dominant reliance on solid biomass and a fuel‐stacking pattern, while urban residences, higher income, and education increase clean energy adoption, highlighting the need for pro‐poor, context ...

Characteristics of longitudinal maternal health studies in sub‐Saharan Africa: A systematic mapping of literature between 2012 and 2022

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 51-62, April 2025.
Abstract Background High maternal mortality rates in sub‐Saharan Africa necessitate the need for aligned research focusing on prevalent causes and neglected conditions in the region. Objective This mapping review aimed to describe the characteristics of longitudinal maternal health studies between 2012 and 2022 in sub‐Saharan Africa and identify gaps ...

Perinatal mortality in eastern Africa: A systematic review and meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Every day, over 5000 stillbirths and more than 6000 newborn deaths are estimated to occur worldwide, the majority in sub‐Saharan Africa and South Asia. Estimates, however, rely on data that might underestimate these deaths. Further, outside major categories such as preterm birth, infection, and complications at delivery, little is ...

Integration of contraception provision in emergency obstetric and neonatal care: A scoping review

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Emergency obstetric and neonatal care (EmONC) provides a framework to assess the capacity of health systems and mitigate maternal mortality. Given the high unmet need for contraception, integrating contraception provision and EmONC services could improve maternal and newborn health outcomes.
