Services Items

• Calculation of Gibbs Free Energy

Our team of experts utilizes state-of-the-art computational methods such as density flooding theory (DFT) and molecular dynamics simulations to accurately calculate the Gibbs free energy of chemical systems and phase transitions. This information is critical for assessing thermodynamic stability, chemical equilibrium, and reaction feasibility.

• Reaction Kinetics

In addition to thermodynamic feasibility, we provide insight into reaction kinetics by analyzing the Gibbs free energy profile along the reaction coordinates. This analysis helps to elucidate reaction mechanisms, rate-limiting steps, and optimal reaction conditions.

• Phase diagram prediction

We use Gibbs free energy calculations to construct phase diagrams that map the stability regions of different phases as a function of temperature, pressure, and composition. These phase diagrams provide valuable information for material synthesis, alloy design, and process optimization.

• Phase Diagram Construction

Using the calculated Gibbs free energy data, we can construct phase diagrams that visualize the stability regions of different phases. These diagrams are indispensable for understanding phase transitions, optimizing material compositions, and predicting phase behavior under varying conditions.

Methods

Methodology

• System definition: We work closely with you to define the system of interest, whether it is a chemical reaction or a phase transition. This includes determining reactant/product, composition, temperature, and pressure conditions.
• Thermodynamic Simulations: Using sophisticated computational methods, we perform thermodynamic simulations such as DFT calculations or molecular dynamics simulations. These simulations evaluate the energy contributions of various components of the system, including enthalpy, entropy, and volume terms.
• Gibbs free energy calculation: By combining the simulated energy contributions with the appropriate thermodynamic equations, we calculate the Gibbs free energy of the system. This parameter provides key information about the thermodynamic behavior, stability, and feasibility of the process.
