Boosting Hydrogen Evolution Electrocatalysis via Regulating the Electronic Structure in a Crystalline-Amorphous CoP/CeOx p-n Heterojunction.

ACS Applied Materials and Interfaces, 2022
The modulation of the electronic structure is the effective access to achieve highly active electrocatalysts for the hydrogen evolution reaction (HER). Transition-metal phosphide-based heterostructures are very promising in enhancing HER performance but ...

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 ...

CoP-Doped MOF-Based Electrocatalyst for pH-Universal Hydrogen Evolution Reaction.

Angewandte Chemie, 2019
Although electrocatalysts based on transition metal phosphides (TMPs) with cationic/anionic doping have been widely studied for hydrogen evolution reaction (HER), the origin of performance enhancement still remains elusive mainly due to the random ...

DE-COP: Detecting Copyrighted Content in Language Models Training Data

International Conference on Machine Learning
How can we detect if copyrighted content was used in the training process of a language model, considering that the training data is typically undisclosed? We are motivated by the premise that a language model is likely to identify verbatim excerpts from
