In crystalline cellulose I, all glucan chains are ordered from reducing ends to non-reducing ends. Thus, the polarity of individual is added forming a large dipole within crystal. If one can engineer unidirectional alignment (parallel packing) crystals, then it might be possible utilize material properties originating polar structures. However, most post-synthesis manipulation methods reported ...

Recently, the existence of so-called granular bubbles and droplets has been demonstrated experimentally. Granular are clusters particles that respectively rise sink if submerged in an aerated vibrated bed another material different size and/or density. However, currently there is no model explains coherent motion these predicts transition between a rising sinking motion. Here, we propose analyt...

Both large deformation and strong discontinuity problems exist in the process of bubble-bubble interaction. The lattice Boltzmann method which is based on the microscopic level has naturally comparative advantage to describe tiny changes in multiphase flow system. A three-dimensional lattice Boltzmann (LB) model of two horizontally aligned bubbles is presented to explore the bubble movement, to...
