The general aim of CEMNAT (Center of Materials and Nanotechnologies), since its foundation in 2013, is to carry out scientific, research and educational activities in materials sciences with use in photonics, electronics, photovoltaics and catalysis. CEMNAT is a true OPEN-ACCESS infrastructure, listed on the Roadmap of Large Research Infrastructures for years 2023-2026 (more information here). Based on its intellectual and instrumental resources CEMNAT provides synergic opportunities to external users from research organizations and companies as well as for own researchers and students.
