Density Functional Theory‐Guided Design and Fabrication of Cu/g‐C3N4 Single‐Atom Catalysts for Efficient Nitrate Reduction to Ammonia

open access: yesRare Metals, EarlyView.
ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐

The Forthcoming General Election in the Republic of Ireland: Winds of (Left‐Wing) Change or Plus Ça Change?

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 180-188, January/March 2025.
Abstract The forthcoming general election will be the most consequential electoral contest for the Republic of Ireland in a century. The polity is situated in truly novel territory with the potential for an historic first: the incoming of a Sinn Féin‐led, left‐wing government.
