Hydrothermal Synthesis and Characterization of the Melamine‐Based SHG Material HgCl2(C3N6H6)

European Journal of Inorganic Chemistry, Accepted Article.
The pursuit of efficient nonlinear optical (NLO) materials is critical for advancing optoelectronic applications. This study focuses on the synthesis and characterization of HgCl2(C3N6H6), a melamine‐based hybrid metal halide. Structural analysis reveals a non‐centrosymmetric lattice facilitated by large asymmetric secondary building units and a π ...

Synthesis and Optical Properties of Ln2Ln′2‐Tetranuclear Lanthanide(III) Complexes

European Journal of Inorganic Chemistry, EarlyView.
A series of new heterotetranuclear lanthanide complexes (Ln2Ln′2) is synthesized to study Ln‐to‐Ln′ energy transfer. Using stable dinuclear precursors, Tb2Yb2 and Nd2Tb2 are prepared and show visible/NIR emission. Reduced Tb3+ lifetimes suggest energy transfer to Yb3+ or Nd3+, offering a modular route to mixed‐lanthanide systems.

On the Applicability of the Advocacy Coalition Framework for Analyzing EU Policy Processes

European Policy Analysis, EarlyView.
ABSTRACT Initially developed for the US context, the Advocacy Coalition Framework (ACF) is increasingly used to analyze policy processes in the EU. But policymaking in EU differs from the US context, why the applicability of ACF in the EU context should be scrutinized.

Design and Optimization of a Robust Wide‐Area Damping Controller for Mitigating Inter‐Area Oscillations in Wind‐Integrated Power Systems

Energy Science &Engineering, EarlyView.
ABSTRACT In power networks, low‐frequency oscillations—particularly inter‐area oscillations—pose a serious threat to system stability because of disruptions like short‐circuit faults and the increasing use of renewable energy sources like wind farms. To lessen the negative impacts of time delays when sending distant signals, this study presents a novel
