Nitrogen-doped carbon-decorated yolk-shell CoP@FeCoP micro-polyhedra derived from MOF for efficient overall water splitting

, 2021
Designing efficient non-precious electrocatalysts to facilitate overall water splitting is crucial and highly desirable but remains challenging. In this study, we synthesized nitrogen-doped carbon-decorated CoP@FeCoP yolk-shelled micro-polyhedras ...

Cop Watch/Cop Listen/Cop Move

Cultural Studies ↔ Critical Methodologies, 2016
In this essay, the authors argue for sound and movement as performative methodologies for studying policing. The proposed performative methodology, “Cop Watch/Cop Listen/Cop Move,” provides a space for (re)seeing, (re)listening, and (re)experiencing policing and, thus, prepares participants to navigate and challenge police surveillance and brutality ...
