Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Advances in Design Strategy and Mechanism Insights for Alkaline Hydrogen Evolution Reaction: Multilevel Site Engineering and Structure–Activity Relationship

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review is about material design based on engineering multilevel sites from theoretical calculation and synthetic routes to mechanism, structure–activity relationship, challenges and perspectives for boosting hydrogen production in alkaline electrolyte. Electrolytic water splitting is a clean, carbon‐free method for producing green hydrogen and has

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

A Longitudinal Comparison of the Effects of Election Outcomes on System Legitimacy in the United Kingdom and United States

European Journal of Social Psychology, EarlyView.
ABSTRACT Using three‐wave panel data from the United Kingdom (N = 604) and the United States (N = 512), we examined changes in system‐legitimization across the 2024 electoral cycle and whether trajectories differed for electoral winners and losers. In both countries, system‐legitimization increased after the election, suggesting that elections function

Improved Spectral Bound for Quasi-Cyclic Codes

IEEE Transactions on Information Theory, 2023
Spectral bounds form a powerful tool to estimate the minimum distances of quasi-cyclic codes. They generalize the defining set bounds of cyclic codes to those of quasi-cyclic codes. Based on the eigenvalues of quasi-cyclic codes and the corresponding eigenspaces, we provide an improved spectral bound for quasi-cyclic codes.

Quasi-cyclic and generalized quasi-cyclic codes and uniqueness of their generators

Discrete Mathematics, Algorithms and Applications, 2022
In this paper, we use a novel approach to describe generator polynomials of quasi-cyclic (QC) and generalized QC (GQC) codes over finite fields. Our study of QC- and GQC-codes will be general and not only restricted to one-generator codes. We prove that generator polynomials of QC-codes and GQC-codes are unique.
