Extraction-Controlled Evaluation of Lactide-Modified Cellulose Prepared by Bulk Ring-Opening Polymerization

This study demonstrates that bulk ring-opening polymerization of lactide on cellulose produces extraction-resistant, cellulose-associated lactide-derived material, likely including grafts, by distinguishing true covalent modification from physically retained homopolymers through a combination of solvent extraction, FTIR carbonyl retention analysis, and thermal characterization.

Reaction Atmosphere-Induced In-Situ Restructuring of FeOx Nanoparticles to Isolated (≡SiO)3–Fe Sites for High-Temperature NH3-SCR

Exposure to a reaction atmosphere induces the in-situ restructuring of FeOx nanoparticles into stable isolated (≡SiO)3–Fe sites within Fe-ZSM-5, which enhances high-temperature NH3-SCR performance by optimizing NO chemisorption and suppressing ammonia overoxidation via a reverse Eley–Rideal mechanism.

Modified expanded polystyrene as partial substitute for lightweight concrete aggregates

This study optimized the heat treatment of expanded polystyrene (EPS) to create modified EPS (MEPS) and found that while substituting MEPS for coarse aggregates significantly reduces concrete compressive strength, replacing fine aggregates with up to 40% MEPS effectively lowers density with a statistically insignificant impact on strength.

Effect of Vanadium Addition on the Microstructure and Mechanical Properties of Si–Mo Ductile Iron at Room and Elevated Temperatures

The addition of vanadium to Si–Mo ductile iron modifies carbide morphology and microstructure, significantly enhancing high-temperature strength, creep-rupture life, and fatigue performance at 800°C despite a trade-off of increased oxide scale susceptibility and a non-monotonic effect on room-temperature strength.

Molecular capping arrests Ostwald ripening of interfacial zinc hydroxide sulfate for reversible zinc electrochemistry

This study demonstrates that the molecular capping agent N-ethyl-2-pyrrolidone (NEP) suppresses Ostwald ripening of interfacial zinc hydroxide sulfate by regulating post-nucleation ageing and reconstructing the solvation environment, thereby creating a stable organic–inorganic interphase that enables highly reversible and long-lasting zinc electrochemistry.
