Kintech Lab develops and implements integrated computer simulation software and information systems for the first principles-based predictive modeling and analysis of the properties of new processes, materials and devices. Kintech Lab completed about 200 scientific research projects in the fields of combustion, chemistry and petrochemistry, plasmachemistry, development of advanced light sources, pollution free energy technologies, energy conversion materials, microelectronics, functional nanostructures, solar cells. Our mission is development and implementation of methodologies for predictive mechanistic modeling. This approach solves the problem of insufficiency of experimental data, unveil a mechanistic picture of the underlying processes, and, hence, reduce the amount of necessary experimental studies. Predictive mechanistic modeling is performed using multilevel approaches based on first-principles methods and interlevel data transfer.
