The effects of microwave power and sample quality on drying kinetics characteristics zirconia were studied. It is found that by increasing the decreasing mass, surface diffusion coefficient (Deff) appears to an upward tendency. corresponding value Deff at a mass 10, 20, 30, 40g are 1.849E-14, 2.443E-14, 3.210E-14, 3.278E-14 m2/s, respectively. 300, 400, 500, 600, 700W 1.270E-14, 1.784E-14, 2.61...

This paper studies the feasibility of using flame spray to produce ZrO2 nano-particles using a liquid precursor. The effects of varying precursor concentrations and ratio of diluting medium on the phase composition, size and morphology of ZrO2 nano-particles are discussed. The morphology and size of the ZrO2 nano-particles was very much dependent on the precursor concentration. The solvent rati...

in this work, a simple and effective way to modify the support surface is developed and a nanostructure ceramic support to facilitate deposition of a defect-free overlying micro and meso (nano) porous membrane is obtained. to achieve high performance nanocomposite membranes, average pore size of outer surface of support was reduced by dip-coating in submicron and nano α-alumina slurries. in thi...

MgO is an important inorganic material, which can be used in many aspects, such as catalyst, toxic-waste remediation agent, adsorbent, and others. In order to make use of MgO, nano-MgO was prepared by ultrasonic method using Mg (CH3COO)2.2H2O as precursor, NaOH aqueous solution as precipitant in this paper. Effect factors on MgO nano-particle size were investigated. Characteristics of samples w...

Contrary to the dislocation-driven ‘smaller-is-stronger’ size-effect in nanocrystals, size-dependence of strength deformation twinning, another carrier plasticity, still lacks universal understanding. Deformation twinning enables pseudoplastic strain >5% a shape memory ceramic (ZrHfO4)x (YTaO4)1−x. We use diffraction methods, microstructure analysis, and in-situ nanomechanical experiments uncov...

The purposes of this study were to investigate the impacts of concentration levels of whey protein isolate (WPI) and inulin on the formation and physicochemical properties of WPI/inulin nano complexes and to evaluate their potential prebiotic effects. WPI/inulin nano complexes were produced using the internal gelation method. Transmission electron microscopy (TEM) and particle size analyzer wer...
