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.

Tailoring Microstructure and Corrosion Performance of In-Situ Alloyed Ti-5Cu-1Si Alloy via Laser Powder Bed Fusion: Impact of Volumetric Energy Density

This study demonstrates that optimizing the volumetric energy density during laser powder bed fusion of Ti-5Cu-1Si alloy refines its microstructure by increasing equiaxed grain density and β-phase fraction while reducing lattice strain, thereby significantly enhancing corrosion resistance through improved passive film stability.

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.

Influence of Fe Doping on the Structural, Electrical, and Room-Temperature Ethanol Sensing Properties of Sol–Gel Spin-Coated TiO₂ Thin Films

This study demonstrates that sol–gel spin-coated TiO₂ thin films doped with 0.5% Fe exhibit optimal room-temperature ethanol sensing performance, achieving a high response of 19.54 to 500 ppm ethanol due to enhanced oxygen vacancies and charge transport, while maintaining excellent stability and durability.
