The mixture was stirred sufficiently and ultrasonic treated for 5 min to facilitate the interaction between titania and pumices.
Molecular weight (MW) degradation, viscosity and anti-inflammatory property of ultrasonic treated polysaccharide were optimized with response surface methodology.
Decreased pore size that accounts for compressive strength improvement was determined in the samples prepared with lower concentration of microwave and ultrasonic treated foaming agent.
Next, the SPIO nanoclusters were prepared following a typical synthetic procedure with minor modification [6, 26, 27], and the SPIO and Alkyl-PEI (ratio 1 0.6) were dissolved in chloroform and ultrasonic treated for 24 h.
Finally, different substances were added to the ultrasonically treated sludge to analyze the effects of ultrasonic treatment on anaerobic digestion.
FTIR spectra of samples ultrasonically treated and untreated confirmed that the initial product of ultrasonic degradation in polymer melts is a macroradical.
After dilution, the SWNT dispersion is treated with an ultrasonic process for 30 min and followed by the PVDF filtration to collect the purified and functionalized SWNTs.
Similarly, Arami et al. [8] produced nanostructured rutile with 15 20 nm crystallite size, which is usually difficult to be obtained at low temperatures, by simply treating in ultrasonic bath the product of dissolution of TiO2 pellets in 10 M NaOH.
