Abstract To meet the needs of the treatment of Cu²⁺ pollution in aqueous solution, the sodium alginate-modified polyacrylic acid (PAA/SA) composite hydrogel was prepared by solution polymerization with acrylic acid (AA) as monomer, sodium alginate (SA) as filler, N, N’-methylenebisacrylamide (MBA) as crosslinking agent, and potassium persulfate (K₂S₂O₈) as initiator. The characterization results showed that the introduction of SA significantly improved the physical and chemical properties of PAA hydrogel materials. Scanning electron microscopy (SEM) showed that as the SA content increased, the materials gradually evolved from a dense blocky structure to a porous network. When the SA… More >

Abstract To comprehensively explore the impact of binder content on the mechanical properties of the Polymer bonded explosive (PBX) substitute material (Polymer-bonded Analogue Explosive (PAE)—it is renowned for its outstanding high-temperature resistance, exceptional mechanical properties, excellent chemical stability, and superior electrical insulation), a series of experiments are meticulously carried out. The dynamic and static mechanical properties, along with the microstructure of PAE, are precisely measured through the Split Hopkinson Pressure Bar (SHPB) test, static compression tests, and Scanning Electron Microscopy (SEM). The dynamic performance test outcomes clearly indicate that both the binder content (2%, 4%, 6%)… More >

Abstract Biobased biodegradable plastics have gained increasing attention as sustainable alternatives to petroleum-based materials in food packaging, offering biodegradability, renewability, and reduced environmental impact. This review adopts a narrative review approach, integrating studies published between 2015 and 2025 from major databases to critically evaluate the recent advances, feasibility, and limitations of biobased biodegradable plastics in food packaging. Literature was thematically analyzed by material type and functional enhancement to assess their feasibility and limitations for sustainable packaging applications. Recent advances have focused on enhancing their mechanical, barrier, and functional properties through polymer blending, nanoparticle reinforcement, and incorporation… More >
