Abstract We investigated the growth mechanism of 2D Mo2C crystals by chemical vapor deposition (CVD) under various time and temperature conditions. The kinetics on Cu via were using a modified Johnson-Mehl-Avrami-Kolmogorov (JMAK) model. To analyze surface coverage, we employed scanning electron microscopy (SEM) applied model to determine rate activation energy. exhibited temperature-dependent ...

in this research, chitosan was used for the removal of cr (vi) ions from aqueous solution. the effect of parameters like solution ph, initial cr (vi) concentration, agitation time, amount of adsorbent and agitation speed on the adsorption process was studied. the experimental equilibrium data were analyzed by using various models such as langmuir and freundlich. freundlich isotherm model fitted...

A mesoscale model is developed by integrating the rate theory and phase-field models and is used to study the fission-induced recrystallization in U-7Mo alloy. The rate theory model is used to predict the dislocation density and the critical size and density of the recrystallized nuclei due to irradiation. The predicted fission rate and temperature dependences of the dislocation density are in ...

In this paper, impacts of day-ahead market pricing on behavior of producers and consumers in option and day-ahead markets and on option pricing are studied. To this end, two comprehensive equilibrium models for joint put option and day-ahead markets under pay-as-bid and uniform pricing in day-ahead market are presented, respectively. Interaction between put option and day-ahead markets, uncerta...

Phytoremediation consists of taking advantage the capacity certain plants to absorb, accumulate, or metabolize contaminants. In this study, Eichornia crassipes (water lily) treated with water (WLW) and NaOH (WLN) was investigated as an adsorbent for removal Ni(II) Cu(II) present in aqueous solution, focusing on determining most efficient conditions (adsorbent concentration, contact time, pretre...
