The mechanical and water vapor permeability of starch/carrageenan cast films were investigated, the rheological properties of starch/carrageenan blends were also studied. The blends were prepared by different concentrations of starch and carrageenan. Three concentration of starch (0.75%, 1% and 1.25%) and two concentrations of carrageenan (0.5% and 0.75%) were used with adding 0.5% glycerol as ...

Abstract The key for improving the mixing efficiency of pseudoplastic fluids is to enhance chaotic degree in flow field. xanthan gum solution was used study characteristics and performance a stirred tank with impeller perturbed six-bent-bladed turbine. Based on velocity time series collected by experiment particle image velocimetry (PIV), distributions largest Lyapunov exponent (LLE) Kolmogorov...

• Alumina microlattices with solid struts were fabricated stereolithography 3D printing . Specific stiffness and specific strength of the best for Simple Cubic design, followed by Octet Truss Kelvin Cell designs. lattices failed column from boundaries into center while fractured along diagonal (110) plane. At low relative densities, microlattice sequentially, due to truss buckling, at high simu...
