Epoxy spacers in gas-insulated substations (GIS) and transmission lines (GITL) accumulate surface charge under HVDC stress, distorting the electric field and lowering flashover voltage. Here, γ-rich alumina and α-Al2O3 nanofillers were synthesized from recycled aluminum beverage cans through acid dissolution, carbonate...

Epoxy-based solid insulation is widely used in high-voltage systems; however, its breakdown reliability and thermal endurance remain critical limitations under coupled electrothermal stresses. This study investigates mesoporous Mg/Al hydrotalcite as a multifunctional nanofiller for enhancing the dielectric, breakdown,...

Crosslinked hydroxyethyl cellulose/epichlorohydrin MnO₂ (HEC/ECH–MnO₂) nanocomposite films were prepared by in situ solution-casting of MnO₂ nanoparticles into a crosslinked (HEC) with (ECH) at five loadings (5–25 wt.%). MnO₂ nanoparticles were chosen for their availability, low cost, and redox-active Mn

Rhipicephalus microplus is a significant ectoparasite of cattle and the emergence of resistance to acaricides has created a need for developing sustainable approaches to its control. The purpose of this study was to prepare green silver nanoparticles with the aqueous extract of the leaves of Ficus carica and assess the...

Antimicrobial resistance (AMR) poses a critical threat to food safety, particularly in African food systems where surveillance infrastructure is limited and climate change is accelerating microbial adaptation. Traditional microbiological risk assessment approaches fail to capture the biological complexity of AMR emerge...

BACKGROUND
Ambient PM2.5 is an IARC Group 1 carcinogen, yet prospective evidence from sub-Saharan Africa remains scarce. We investigated long-term exposure to PM2.5, PM10, and NO₂ and incident cancer risk in a Nigerian adult cohort.
METHODS
We studied 5621 adults across Lagos, Kano, and Rivers States with median foll...

Poly(ADP‐ribose) polymerase‐1 (PARP‐1) plays a central role in the repair of DNA single‐strand breaks and represents an established therapeutic target in cancer treatment. In this study, a series of novel oxadiazole–morpholine hybrid compounds was designed and synthesized using a structure‐based drug design approach to...
