When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

Sustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

Water Droplet Hammer: Piezoelectric Sensing of Ultrafast Mechanical Transients During Droplet Impact

Small, EarlyView.
Droplet impact on solid surfaces produces an ultrafast substrate‐coupled mechanical response that is resolved by PVDF piezoelectric sensing. An initial impulsive strain pulse is followed by interfacial oscillations before rebound. Weber‐number and timescale analyses reveal how droplet inertia, surface wettability, impact regime, and liquid viscosity ...
