In this research, crystallization of Fe36Cr12Mo10 and α-Fe phases in devitrification of Fe51Cr18Mo7B16C4Nb4 amorphous alloy was studied using X-ray diffraction and transmission electron microscopy. For evaluation of crystallization kinetics, differential scanning calorimetric tests were carried out at different heating rates. Results showed that two-step crystallization led to the formati...
The super-saturation condition has to be provided to form gas hydrates. Consequently, the prediction of the guest molecule fraction in the aqueous phase is crucial in the study of the gas hydrate kinetics. In the present work, several experiments were carried out in a semi-batch reactor in order to determine the mole fraction of methane and ethane during gas hydrates formation (growth stage...
two different growth media, namely complex and defined media, were used to examine establishment of steady-state conditions in phosphate-limited culture system of saccharomyces cerevisiae cen.pk113-5d strain. using the defined growth medium, it was possible to obtain steady state condition in the continuous culture. the effect of phosphate concentration on the growth of s. cerevisiae in phospha...
