Thermo‐Kinetic Design of Magnesiothermic Reduction for Morphology‐Retaining Porous Si@C Anodes

Small, EarlyView.
Balancing Mg‐vapor supply and surface consumption during magnesiothermic reduction suppresses particle aggregation and preserves monodisperse morphology in porous Si@C spheres. The resulting architecture improves transport uniformity and reduces degradation within the electrode, leading to more stable high‐capacity cycling than aggregated counterparts ...

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

Support, reciprocity, and kinship as seeds of Indigenous family resilience during COVID‐19

Family Relations, EarlyView.
Abstract Objective Our goal was to better understand the impact of COVID‐19 on Indigenous family coping. The focal research question was the following: What protective factors do Indigenous women cite as buffering stressors related to COVID‐19 for themselves and their families? Background During the COVID‐19 pandemic, Indigenous peoples experienced the

A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.
