Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.

Interplay Between Dispersion, Nucleation, and Crystallization in HDPE/Graphene Nanocomposites Processed Under Thermokinetic Conditions

Polymer Engineering &Science, EarlyView.
Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

steel research international, EarlyView.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.
