## Description

- description: Glass bead–fiber mixed porous materials with tunable interconnected
    channel structures were prepared, and the influence of fiber-induced channel subdivision
    on water-flow behavior was investigated using X-ray CT–based analyses. Incorporation
    of milled glass fibers into interconnected channels formed between fused glass
    beads effectively subdivided relatively large channels. As a result, the number
    of pores increased and the average pore size decreased without major changes in
    overall porosity. CT-based flow analyses revealed that increasing fiber content
    reduced local water velocity and generated heterogeneous preferential flow pathways
    associated with channel subdivision. Tracer-particle analysis further indicated
    limited lateral displacement within the porous structures, indicating restricted
    transport pathways despite local flow heterogeneity. These results demonstrate
    that subdivision of interconnected channels influences local transport behavior
    in sintered glass-based porous materials. Preliminary microplastic capture experiments
    further indicated that incorporated fibers and additional layered double hydroxide
    deposition contributed to particle retention within the interconnected channels.
    Thus, this study provides a basis for designing structure-flow relationships in
    sintered glass-based porous materials.
