Stage-Resolved Characterization of Wastewater Sludge Streams for Thermochemical Valorization: Moisture, Fuel Value, and Ash Mineralogy Constraints

This study characterizes five distinct sludge streams from the Ankara Central Wastewater Treatment Plant to demonstrate that treating wastewater sludge as a uniform feedstock is flawed, as thermochemical viability shifts from being moisture-limited in upstream streams to being constrained by high ash content and mineral residue behavior in downstream streams.

Quantifying Structural and Elemental Contributions to Local Electric Fields on Metal Nanoclusters with Interpretable Machine Learning

By integrating density functional theory with interpretable machine learning, this study reveals that local geometry, rather than metal identity, is the primary determinant of local electric fields on transition-metal nanoclusters, enabling the development of highly accurate and interpretable predictive models for field-assisted catalysis.

Ionic-Layer Engineering Enables Propeller-Type Interstitialcy Oxygen Migration in Close-Packed Perovskite Solid Electrolytes

This study introduces an ionic-layer engineering strategy in close-packed perovskite solid electrolytes that reinterprets highly coordinated alkaline-earth sublattices as flexible motifs to enable propeller-type interstitial oxygen migration with low activation energy, offering a new design framework for oxide-ion conductors beyond conventional vacancy-mediated mechanisms.

Integrated processing of heterogeneous waste plastics through controlled thermal consolidation and contaminant managementIntegrated processing of heterogeneous waste plastics through controlled thermal consolidation and contaminant management

This study demonstrates the feasibility of recovering resource value from large, unshredded heterogeneous industrial plastic waste bales by subjecting them to controlled thermal consolidation and mechanical compression, thereby bypassing conventional preprocessing steps like shredding, cleaning, and complete remelting.
