... reports about the effects of particle size and biomass crystallinity on sugar yield (proportional to biofuel yield). An important reason for this inconsistence is that particle formation in current size reduction methods is not well controlled, causing the effects of these two variables confounded. One...

..., WI) was employed to reduce the particle size of poplar wood. Figure 5 shows the milling cutter that was installed in the tool holder of the machine. It was a Slot Master® indexable milling cutter (Model SM612158, Republic Drill APT Corporation, Melrose Park, IL). Twelve carbide inserts were...

... is inelastic, dissipative force exits, leading to energy loss in every collision. The interparticle contact force is calculated based on the nonlinear Hertz theory. The packing structures quantified by porosity and the coordination number under different particle size distributions are discussed...

... the impact of electrostatic and Brownian motion forces on the progression of partial blocking. The simulations also examine the effects of fluid velocity, particle size, and particle surface potential. The inclusion of electrostatic and Brownian forces is shown to significantly impact the progression...

... dynamic methods are employed to model both a portion of a sintered alumina membrane with tortuous pores and the microemulsions passing through it. Several particle size distributions, measured experimentally at various times through the membrane service life and under two different cross-flow velocities...

... in reducing the size of ceramic micro- and/or nanoparticles to a desirable range to be used as a constituent for micro- and nanostructured materials. In this study, the time change of particle size of titanium dioxide TiO 2 micro- and nanoparticles in the stirred ball mill grinding process is characterized...

... for CMP processes. The proposed model also reveals that the nature of the slurry-pad interaction mechanism, and its associated force partitioning mechanism, is important for determining the variation of MRR with particle size and concentration. It is observed that under relatively soft pads, small...
