Since 2018, KosarTech Group has commenced its activity focusing on the implementation of practical research projects within the academic disciplines of surface science and thin-film physics and on repair, maintenance, and malfunction detection of deposition devices and vacuum systems. Having partaken in various scientific and industrial projects, the group resolved to actively engage in content creation in the digital world with the aim of enhancing the practical ability and knowledge in the field of the physics and chemistry of surfaces. Therefore, the KosarTech website was launched in 2020, which is a platform offering the services of consultation, quality control, installation and malfunction detection of equipment, and content creation in the fields mentioned. Additionally, it provides students, researchers, scientists, technologists, and industrialists with the opportunity to broadly share their experiences, optimally undertake their research projects, and reliably foresee the trend of the developments occurring in surface science and thin-film physics.
