Nanocomposite mullite/mullite powders by spray pyrolysis
A mullite/mullite nanocomposite powder has been synthesized, composed of nanometer-size 3Al2O3 · 2SiO2 (‘3 : 2’) mullite precipitates within a matrix of the high alumina 2Al2O3 · SiO2 (‘2 : 1’) mullite. Historically, the transition from the metastable high-alumina phase to the thermodynamically stable ‘3 : 2’ phase of mullite has been thought to be a continuous process, involving a continuous s...
متن کاملPorous carbon powders prepared by ultrasonic spray pyrolysis.
New, thermally robust meso- and macroporous carbon powders were prepared by ultrasonic spray pyrolysis (USP) of aqueous solutions using an inexpensive high-frequency ultrasound generator from a household humidifier. We choose our molecular precursors rationally, so that the expected decomposition pathways produce only remnant carbon atoms. Specifically, our rational design criterion led to halo...
متن کاملIntensification of Probiotic Microorganisms Viability by Microencapsulation Using Ultrasonic Atomizer
Uscarea prin pulverizare este o metodă frecvent folosită la încapsularea microorganismelor probiotice. În prezentul studiu a fost utilizat duză ultrasonică de 120 kHz pentru a obţine granule foarte fine, care pot fi folosite în produse lactate probiotice. Celule de bacterii lactice au fost încapsulate în alginat şi maltodextrină prin atomizare cu ultrasunete. Încapsularea a fost realizată pentr...

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
Characterization and Phase Transformation of Spherical YSZ Powders Fabricated Via air Plasma Spray Method
Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...
