machine for reaction path calculation

We received an inquiry regarding the introduction of a machine for research on alloy catalysts.Specific applications and conditions are as follows.

・Using Quantum ESPRESSO with Winmostar, it is assumed to calculate the surface electronic state, calculate the system in which reactive species (propylene, hydrogen, etc.) are adsorbed, and calculate the reaction path by the NEB method.

・Since metal compounds are used, some of them have more than 10 atoms in the unit cell.

・Since this is an estimate for budget application, the specific budget has not been decided, but for the time being, it is assumed to be about 50 yen.

From our company, we proposed a configuration that we considered with an amount close to the budget of 50 yen.
