Women's empowerment and its association with fertility preference are vital for central-level promotional health policy strategies. This study examines the association between women's empowerment and fertility decision-making in low and middle resource countries (LMRCs). This cross-sectional study uses the Demographic and Health Survey database. 53 LMRCs from six different regions for the period ranging from 2006 to 2018. The data of women-only aged 35 years and above is used as a unit of analysis. The final sample consists of 91 070 mar

Revealing the active phase and structure of catalyst nanoparticles (NPs) is crucial for understanding the growth mechanism and realizing the controlled synthesis of carbon nanotubes (CNTs). However, due to the high temperature and complex environment during CNT growth, precise identification of the active catalytic phase remains a great challenge. We investigated the phase evolution of cobalt (Co) catalyst NPs during the incubation, nucleation, and growth stages of CNTs under near-atmospheric pressure using an in situ close-cell env
