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

open access: yesENERGY &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

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Bridging computational and clinical strategies for presurgical identification of epileptogenic networks

open access: yesEpilepsia Open, EarlyView.
Abstract Objective About one third of epilepsy patients are drug‐resistant. Resective epilepsy surgery remains a key treatment option but depends critically on accurate identification of the seizure onset zone (SOZ), which is still guided mainly by subjective visual inspection of electrophysiological signals.

Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization

open access: yesEnergy Science &Engineering, EarlyView.
The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...
