## Description

- description: Concentrated suspensions of micrometer-sized particles exhibit a unique
    rheological behavior that is strongly dependent on the shear rate and shear stress.
    Corn-starch suspensions, which are starch particles from corn plants, have been
    extensively studied as model samples for concentrated suspensions exhibiting discontinuous
    shear thickening (DST) and dynamic shear jamming (SJ). However, starch particles
    from other plant sources have not yet been investigated, despite their different
    sizes and shapes. This study investigated the effects of the structural parameters
    of starch particles by preparing concentrated suspensions of starch particles
    from 13 different plants at particle fractions of 25%–50% and evaluating their
    rheological behaviors through steady shear, pull-out, and ball-drop tests. Starch
    particles can be classified as polygonal and ellipsoidal. The DST and SJ behaviors
    typically reported for concentrated cornstarch suspensions were confirmed for
    other starch particles in both particle groups. The ball-drop test demonstrated
    excellent shock absorption properties for 11 concentrated suspensions of starch
    particles, except for sago palms. In the case of concentrated suspensions of starch
    particles, the particle fraction and shear applied were the dominant factors that
    significantly affected the rheological behavior, whereas the particle shape was
    not a primary contributor. This study confirms the possibility that the properties
    of the liquid in a particle suspension can significantly affect the DST and SJ
    behaviors.
