The use of electrocoagulation (EC) and anodic oxidation (AO) processes was studied for improving a treatment system for landfill leachates based on a membrane bioreactor (MBR) and a nanofiltration step. The main limitation of the current full-scale system is related to the partial removal of organic compounds that leads to operation of the nanofiltration unit with a highly concentrated feed solution. Application of the EC before the MBR participated in partial removal of the organic load (40 %) with limited energy consumption (2.

Article Synopsis
- In rural Burkina Faso, a study was conducted to assess the impact of combining Seasonal Malaria Chemoprevention (SMC) with nutrient supplementation among undernourished children under five years old, due to high levels of both malaria and malnutrition in the area.
- The study involved 1059 children divided into three groups, each receiving different combinations of SMC and nutritional interventions, followed over a year to monitor malaria incidence and overall health through regular check-ups.
- Results showed that adding lipid-based nutrient supplements (PlumpyDoz) significantly reduced both uncomplicated malaria (by 23%) and severe malaria (by 52%) compared to the control group, also lowering general illness rates by 24%, while no effect was found on
Article Synopsis
- This study explored how stable lead halide perovskites are under normal conditions when combining Formamidinium (FA) and Cesium (Cs) cations.
- The researchers prepared CsFAPbI solutions with varying Cs and FA ratios, deposited them using spin-coating, and analyzed their properties through techniques like XRD and SEM.
- Results indicated that the mixed perovskites maintain a stable crystal structure and exhibit better durability compared to pure FA and Cs films, with the best solar cell efficiency simulation reaching approximately 22.36%.
Seasonal Malaria chemoprevention (SMC) is one of the large-scale life-saving malaria interventions initially recommended for the Sahel subregion, including Burkina Faso and recently extended to other parts of Africa. Initially, SMC was restricted to children 3 to 59 months old, but an extension to older children in some locations was recently recommended. Further characterization of SMC population profile beyond age criterion is necessary for understanding factors that could negatively impact the effectiveness of the intervention and to define complementary measures that could enhance its impact.

Both processes achieved high TOC removal. A yield of 95 % was obtained by combining EF with BDD anode during 6 h of treatment.
