ChemSheet - from computational thermodynamics to spreadsheet engineering

ChemSheet is one from the internationally renowned ChemSage/FactSage family of thermochemical calculation programs, which are extensively used in universities as well as in corporate and government laboratories. With its pioneering Excel interface, ChemSheet offers new possibilities and practical advantages to both scientists and engineers in the use of thermochemical calculations across a wide spectrum of applications by providing the easy-to-use spreadsheet approach towards complex thermodynamic multi-phase problems. ChemSheet offers the same library of subroutines for data handling and phase equilibrium calculation purposes, which are included in the ChemApp Gibbs energy solver. In addition to the predetermined mass balance constraints, which are used for chemical and phase equilibria in Gibbs energy calculations, within the frame of ChemSheet it is easy to use dynamic and immaterial constraints. They allow for calculation of systems controlled by work factors (either systemic or externally induced) as well as of processes controlled by chemical reaction kinetics. Thus, solving e.g. surface and interface energies, Donnan potentials and simulation of chemical or biochemical reaction pathways can be performed.
