Kinetics Influence of Operation Conditions on Crystal Growth of Calcium Nitrate Tetrahydrate in a Circulating Fluidized Bed

In order to improve the traditional freezing crystallization process of calcium nitrate in nitric phosphate process, crystal growth experiments by adding Ca(NO3)2·4H2O seeds in supersaturated calcium nitrate solution in a Circulating Fluidized Bed (CFB) crystallizer were carried out on crystal growth kinetics. The results showed that the growth of C...

Quantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics

Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size 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 ...

Effect of Temperature and pH on the Growth Kinetics and Carotenoid Production by Sporobolomyces ruberrimus H110 Using Technical Glycerol as Carbon Source

A new isolated strain of Sporobolomyces ruberrimus H110 was cultivated  on technical glycerol as carbon source and effect of different temperatures and pH on the growth and pigmentation was studied. The maximum concentration of total carotenoid was 3.84 mgg-1 including torularhodin (3.70 mgg-1) and β-carotene (0.14 mgg-1) using 19ºC at pH 6, but the highest ...

Mathematical Models for Microbial Kinetics in Solid-State Fermentation: A Review

  Context:In this review, we discuss empirical and stoichiometric models, which have been developed recently in SSF processes and the influence of environmental conditions on the variables of these models. Additionally, new studies on modeling of product formation are also mentioned. <span style="color: windowtext...

Growth Kinetics and in Vitro Aging of Mesenchymal Stem Cells Isolated From Rat Adipose Versus Bone Marrow Tissues

Objective- To investigate and compare growth potential as well as aging of mesenchymal stem cells (MSCs) derived from rat bone marrow tissue and adipose tissue (AT) occurred at epicardial and epididymal regions. Design- Experimental study.   Animals- 10 Wistar Rats.   Procedures- Rat MSCs occurred at bone marrow and epicardial and epididymal AT were isolated and culture expanded through sev...
