Ultrasound (US) serves as a stimulus to change shear viscosity of aqueous polysaccharides of ι-carrageenan, κ-carrageenan and, agar. The US effect was compared in their aqueous solutions at 60 °C for the US frequency of 23, 45, and 83 kHz. Under the US condition with 50 W at 45 kHz, the shear viscosity of each aqueous solution was decreased significantly.(More)
The design and optimization of a coupled multicomponent distillation system is a non-linear and multivariable problem. The complexity of this kind of problem results in high solving difficulty. This paper addresses the application of genetic algorithms to the optimization of intensified distillation systems for quaternary distillations. We used a(More)
The effect of ultrasound (US) stimulation on the shear viscosity of aqueous polyvinyl alcohol (PVA) solution was studied when the solution was exposed to US at 23, 43, 96, and 141 kHz. The US stimulus showed a marked decrease of the shear viscosity of the solution in the order of 43>96>23>141 kHz, respectively, under US power dissipation of 8.5, 8.9, 8.9,(More)
Ultrasound (US) exposure strongly influenced thermosensitivity of microgels attracted with both N-isopropylacrylamide (NIPAM) and acrylic acid (AA) segments, due to that hydrogen bonds of carboxylic acid segments in microgels were broken by US and then the hydration with water occurred. US induced critical effects on the volume phase transition temperature(More)
