GAS Antisolvent Crystallization of Aspirin Using Supercritical Carbon Dioxide: Experimental Study and Characterization
antisolvent addition, process temperature, solute concentration and the solvent type (methanol and acetone) on the final product particle size distribution, morphology and crystallinity. In accordance to particle size analysis and scanning electron microscopy...
Quantum Dots of CdS Synthesized by Micro-Emulsion under Ultrasound: Size Distribution and Growth Kinetics
distribution and the
growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time.
In addition, an agreement was observed with the size distribution obtained from...
The effect of particles size on work hardening behavior of a low carbon steel with a composite-type microstructure
of bimodal particle size distribution on the work hardening was also evaluated. Although the addition of a certain amount of fine particles to the steel microstructures containing coarse particles has a main role in the enhancement of isotropic contribution...
Making Oil-in-Water Emulsions by Ultrasound and Stability Evaluation Using Taguchi Method
size distribution of samples was investigated using
Taguchi statistical method. The results showed that increasing sonication time decreased mean
diameter of droplets and narrowed droplet size distribution curves. NaCl was found to have a...
Survival of Microencapsulated Potential Probiotic Bacteria in Simulated Gastric Juice
.05). After sequential incubation in simulated gastric (60 min), number of surviving cells was 6.5 log cfu mL-1 for L. acidophilus and 7.5 log cfu ml -1 for L. rhamnosus while 2.2 log cfu ml -1 was obtained for free cells. Particle size distribution...
A Kinetic Modeling of Particle Formation by Gas Antisolvent Process: Precipitation of Aspirin
particle size distributions were produced which were in an acceptable agreement with the experimental data of the investigated system....
