Impact of Bi-Axial Shear on Atherogenic Gene Expression by Endothelial Cells
This study demonstrated the effects of the directionality of oscillatory wall shear stress (WSS) on proliferation and proatherogenic gene expression (I-CAM, E-Selectin, and IL-6) in the presence of inflammator...

Mixing analysis of PCS slurries in a horizontal scraped surface bioreactor
Horizontal rotating reactors offer many advantages for enzymatic hydrolysis of viscous biomass slurries; however, they do not provide homogenous mixtures since motion is only in the angular direction. Multi-di...

Enzymatic Saccharification and Viscosity of Sawdust Slurries Following Ultrasonic Particle Size Reduction
Results in a previous study showed up to a 55% increase in saccharification rates when the initial particle size range decreased from 590 < x < 850 μm down to 33 < x < 75 μm. The smaller particle sizes also lower...
