Relation between extensional viscosity and polymer conformation in dilute polymer solutions
Yusuke Koide, Takato Ishida, Takashi Uneyama +1
We investigate extensional viscosity and polymer conformation in dilute polymer solutions under uniaxial extensional flow using dissipative particle dynamics simulations. At high e…
A Review on Molecular Simulations for the Rupture of Polymer Networks
Yuichi Masubuchi, Takato Ishida, Yusuke Koide +1
Molecular simulations provide a powerful means to unravel the complex relationships between network architecture and the mechanical response of polymer networks, with a particular…
Influence of Stretching Boundary Conditions on Fracture in Phantom Star Polymer Networks: From Volume to Cross-sectional Area Conservation
Yuichi Masubuchi, Takato Ishida, Yusuke Koide +1
This study systematically investigates the effect of stretching boundary conditions, ranging from conservation of cross-sectional area to conservation of volume, on the rupture beh…
Steady-state extensional viscosity of wormlike micellar solutions via dissipative particle dynamics simulations
Yusuke Koide, Takato Ishida, Takashi Uneyama +1
We investigate the steady-state extensional viscosity of wormlike micellar solutions using dissipative particle dynamics simulations. As the extension rate increases, the steady-st…
Direct observation of the compression behavior of polystyrene microbeads in a diamond anvil cell
Haruto Moriguchi, Ken Niwa, Masashi Hasegawa +4
The pressure dependence of the bulk modulus of glassy polystyrene (PS) was measured in the relatively high-pressure regime, up to 6 GPa, at ambient temperature. For the measurement…
Effects of Stirring Time on Formation of Microplastics Fragmented from Photo-aged Polypropylene
Kazuya Haremaki, Takumitsu Kida, Yusuke Koide +3
This paper examines the evolution of microplastic (MP) size distributions fragmented from photo-aged polypropylene (PP) in stirred water. PP specimens fragmented into MPs with thei…
