Cash, Credit, or Kin? Financing Pathways and the Uneven Sustainability of Off‐Grid Solar Electrification in Tanzania and Malawi

open access: yesSustainable Development, EarlyView.
ABSTRACT Solar home systems (SHSs) are celebrated as a technological antidote to sub–Saharan Africa's chronic electricity deficits, yet the financial and social mechanisms that move them from warehouse to household remain underexplored. Drawing on 157 interviews with SHS owners in Tanzania and Malawi, this study examines the financial pathways used to ...

Tunable Self‐Emulsification Via Viscoelastic Control of Marangoni‐Driven Interfacial Instabilities

open access: yesSmall Methods, EarlyView.
A striking interfacial instability–Marangoni bursting–is tamed by introducing trace polymers. Minute amounts of viscoelastic additives delay fragmentation, elongate fingers, and modulate instability wavelengths without altering droplet size. This study reveals how soft matter rheology can program self‐emulsification dynamics, offering new routes for ...
