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

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Ceria Nanostructures Obtained by Hydrothermal Synthesis: Exploring the Experimental Parameter Landscape for Precise Morphology and Size Control

European Journal of Inorganic Chemistry, EarlyView.
Hydrothermal and microwave‐assisted syntheses enable systematic tuning of ceria nanostructure morphology. Chloride counter‐ions direct nanorod growth, while an acetate buffer yields uniform nanocubes whose size (14–26 nm) is tuned via the reactor filling ratio, with microwave heating significantly cutting reaction times to minutes while preserving high

Multiphysics Coupled Response of Stress and Seepage in Coal Under Borehole Disturbance and Optimization of Borehole Parameters

Energy Science &Engineering, EarlyView.
One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole
