Ion Charge Compensation upon Electrochemical Doping of Redox Polymer Films with Tunable Crosslinking Density

open access: yesAdvanced Electronic Materials, Volume 12, Issue 6, 23 March 2026.
The electrochemical doping of redox homo‐ and copolymers containing triphenylamine (TPA) as redox‐active units is reported. Electrochemical crosslinking leads to films with tetraphenylbenzidine (TPB) crosslinking units. Advanced electrogravimetric tools are applied to get insights into their mixed ionic‐electronic conducting characteristics: anion ...

Corporate Sustainability Performance and Fraud Risk Management in Nigeria's Extractive Sector: The Moderating Role of Ownership Structure in an Evolving Environmental Policy Landscape

open access: yesCorporate Social Responsibility and Environmental Management, Volume 33, Issue 2, Page 2906-2927, March 2026.
ABSTRACT Using the environmental quality cost management model, this study examines how fraud risk management (FRM) influences corporate sustainability performance (CSP) and how ownership structures moderate it. The study uses artificial neural networks (ANN) and logistic regression models to test two hypotheses. H1 demonstrates that the prevention and
