Application of Fe₃O₄ magnetite nanoparticles grafted in silica (SiO₂) for oil recovery from oil in water emulsions by Wamda Faisal Elmobarak (17058024)

“…Using an MD_dose as low as 10 mg/L attained a %_hdem in the range of 93% - 4.3% for O/W mixtures with C_oil < 2000 mg/L, which slightly decreased to ~90% for higher concentrations. The reported %R_oil(p-value <0.05) was >90 ± 0.1 for tests carried out with pH 7 and C_sur0.1 g/L and declined at higher pH and Csur to % 86.5 due to the increase in emulsion stability. …”

Global, regional, and national burden of household air pollution, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021 by Fiona B, Bennitt

“…FindingsIn 2021, 2·67 billion (95% uncertainty interval [UI] 2·63–2·71) people, 33·8% (95% UI 33·2–34·3) of the global population, were exposed to HAP from all sources at a mean concentration of 84·2 μg/m3. Although these figures show a notable reduction in the percentage of the global population exposed in 1990 (56·7%, 56·4–57·1), in absolute terms, there has been only a decline of 0·35 billion (10%) from the 3·02 billion people exposed to HAP in 1990. …”

Migration frameworks in Africa by Alemu Asfaw Nigusie (16962900)
