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 ...

Designing “Korean” Kimchi: Speculative Configuration of Distance and Commodity Value in the Chinese Kimchi Industry

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT In the Chinese kimchi industry, manufacturers employ product names, photographs, and logistical strategies to promote their kimchi's “Koreanness.” So, what makes their kimchi “Korean,” and how does its Koreanness formulate kimchi's commodity value?

The Formation and Transformation of Low‐Dimensional Carbon Nanomaterials by Electron Irradiation

open access: yesSmall, EarlyView.
The article reviews irradiation phenomena in graphene‐ or graphite‐based nanomaterials from the scale of single atoms to tens or hundreds of nanometers. Observations dating back to the 1990s can now be explained on the basis of new results. The evolution of the understanding during three decades of research is presented, and the remaining problems are ...

Preserving the Surface Activity of Lung Surfactant Using Soft Nebulization

open access: yesSmall Science, EarlyView.
This study examines the integrity and surface activity of animal‐derived lung surfactant under different nebulizations. Low‐energy nebulization preserves lamellar structures of the surfactant, enhancing rapid spreading and stability in maintaining low surface tension during interface area changes.

Macroscale Superlubricity with a High Load‐Carrying Capacity Enabled by Nitrogen‐Doped Graphene Quantum Dots in Lubricated Silicon‐Doped Amorphous Carbon Films

open access: yesSmall Structures, EarlyView.
Achieving superlubricity in aqueous‐lubricated systems for energy conservation remains challenging. Here, a newly developed nanolubricant based on nitrogen‐doped graphene quantum dots (NGQDs) enables robust superlubricity between steel and silicon‐doped amorphous carbon film.
