Physicochemical Properties and Antibacterial Activity of Gellan Gum Incorporating Zinc Oxide/Carbon Nanotubes Bionanocomposite Film for Wound Healing
Published 2022-01-01“…The characterization results confirmed the reinforcement of the gellan gum (GG) matrix with zinc oxide nanoparticles (ZnONP) and multiwall carbon nanotubes (MWCNT), as an amorphous GG/ZnONP + MWCNT bionanocomposite film was obtained. SEM morphological analysis shows that the addition of ZnONP and MWCNT nanofillers changed the film microstructure into a sponge-like structure that is more suitable for fluid uptake and thus more useful for wound healing. …”

Creep of Sn-0.3Ag-0.7Cu solder in electronic packaging: Experiment and simulation
Published 2025-01-01“…In contemporary society, the growing reliance on electronic devices has necessitated the phasing out of traditional Sn–Pb solder due to its health hazards, prompting a transition to environmentally friendly, lead-free alternatives.This study aims to address the challenges of poor interfacial reliability and high cost associated with eutectic Sn–Ag–Cu solders by investigating the creep properties and service life of a low-silver solder alloy, Sn-0.3Ag-0.7Cu, as a filler material.The creep behavior of Sn-0.3Ag-0.7Cu was analyzed through creep testing, and fracture modes were identified via microstructural and fracture surface analysis.The Anand viscoplastic model was employed to simulate and calibrate the creep behavior, with its accuracy validated via thermal cycling experiments.Furthermore, the creep behavior of Ball Grid Array (BGA) solder joints was simulated using Abaqus software to examine the impact of creep on joint longevity and the influence of temperature on performance.…”

Strengthening mechanisms of a near-α titanium alloy with high strength and impact resistance
Published 2025-09-01“…In this work, we report a new discovery of obtaining a near-α titanium alloy with both high tensile yield strength (∼1050 MPa) and high Charpy impact absorbed energy (∼45 J). Microstructural and theoretical analysis reveal that the high strength is attributed to the dislocation strengthening and grain boundary strengthening, and the high Charpy impact absorbed energy of the alloy results from the combined effects of dislocation multiplication, twinning deformation and the transformation of α-Ti to FCC-Ti. …”
