Governing by Ambiguity: Sociotechnical Imaginaries of Platforms in China
Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT Besides clear policy directives, the unresolved and open‐ended elements in policy communication also create discursive politics. This article argues that ambiguity in policy communication reflects the state's exercise of power within a fractured sociocultural landscape.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...
