SCAPS-1D-guided design of high-efficiency lead-free Cs2CuSbBr6 double-perovskite solar cells

Lead-free, Cs 2 CuSbBr 6 is a promising candidate due to its improved intrinsic stability and environmental compatibility. In this work, we present a detailed theoretical study of perovskite solar cells based on Cs 2 CuSbBr 6 , which is conducted utilizing the SCAPS-1D platform....

A systematic review of geospatial and meteorological approaches to flood risk assessment and monitoring

Abstract Increasing flood frequency, exposure and impacts associated with climate change, rapid urbanisation, and environmental change have intensified the need for robust flood risk assessment and monitoring frameworks. This systematic review synthesises advances in geospatial,...

Association between early sexual debut and HIV infection among adolescent girls and young women in Cameroon: does motherhood modify the relationship?

Abstract Background In Cameroon, where HIV prevalence among Adolescent girls and young women (AGYW) remains nearly double that of their male peers, limited evidence exists on how early sexual debut and motherhood jointly shape HIV risk. This study examines the association between...

Larvicidal Activity, GC–MS Profiling and Multitarget Molecular Docking of Essential Oils from Cymbopogon citratus, Tanacetum cinerariifolium and Salvia rosmarinus Against Anopheles arabiensis

Malaria remains a major public health challenge, particularly in sub-Saharan Africa, necessitating the development of environmentally sustainable alternatives to conventional insecticides. This study evaluated the larvicidal efficacy of essential oils extracted from Cymbopogon ci...
