Synthetic Engineering of Manganese Oxide–Carbon Nanocomposites for Maximized Metal Utilization in Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...

Copper Catalyzed Anisotropic Dissolution of Silicon in HF–HCl Solutions: Metal‐Assisted Chemical Etching Without Additional Oxidant

European Journal of Inorganic Chemistry, EarlyView.
Metal‐assisted chemical etching without an oxidant? We report an unexpected Cu2+‐catalyzed anisotropic etching of silicon in HF–HCl solutions. Despite the low redox potential of Cu2+, pyramidal surface structures are generated without a distinctive additional oxidizing agent.

Policy Entrepreneurs and the Design of Administrative Reform: A Conceptual Framework and the Israeli Case

European Policy Analysis, EarlyView.
ABSTRACT What is the role of policy entrepreneurs in promoting the design of public administrative reform? We present a conceptual framework for assessing the influence of policy entrepreneurs on public administrative reform. We start by proposing a typology of the various policy entrepreneurs active in the administrative reform arena.

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

European Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled

Winning Legitimacy and Dodging Blame: How Government Communication Shapes Media Sentiments and Responsibility Attribution in Consensus Democracies

European Policy Analysis, EarlyView.
ABSTRACT How do governments' discursive credit‐claiming and blame‐deflection strategies shape perceived policy legitimacy in times of crisis? Despite the importance of legitimacy in conflictual times, systematic analyses of officeholders' credit‐claiming and blame‐deflection strategies and their effect on perceived legitimacy are still rare.
