Description

IMNR, established over 50 years ago, is a national R&D institute active in the field of materials science and engineering based on non-ferrous and rare metals (alloys, composites, hybrids) and applied inorganic chemistry, aiming to further research for the efficient use of resources and critical materials substitution, and develop high-tech applications in sensors, security, energy, automotive, aerospace, medicine, waste management, etc.

The institute’s main research directions include: technologies for advanced metal-based materials and their compounds; new chemical processes for processing primary and secondary resources (solubilization in autoclaves in controlled atmosphere, microwave processing); mild chemical methods for the synthesis of advanced nanomaterials (oxides, composites, hybrids): hydrothermal / solvothermal at high pressures, spray drying, encapsulation and core-shell materials; new technologies for capitalizing advanced materials (coatings and thin films by EB-PVD, and thermal evaporation depositions, electro-deposition in aqueous solutions and molten salts, hydrothermal-electrochemical deposits with real-time RAMAN monitoring). The quality of its R&D results has led to the institute's continued presence in international projects funded by programs such as: NATO-SFP, FP5, FP6, FP7, Horizon2020 and bilateral co-operations.

Through the Technology Transfer Center for Advanced Materials CTT AVANMAT, IMNR aims to implement and capitalize on the results obtained in the R&D activity in the field of biomaterials, intelligent materials and sensors, increasing competitiveness, and supporting long-term economic and social development.

IMNR also aims to extend and strengthen its partnerships and collaborations with the European scientific community. Currently IMNR is coordinating the SUPERMAT Virtual Center, is a member of 1 EU Association (SPIRE), 1 EU Alliance (ERMA), 1 EU Network (CircLean), 4 COST Action Networks (ITHACA, CRM-EXTREME, BIONECA, HERALD), 4 European Technology Platforms (NANOFUTURES, NANOMEDICINE, RAW MATERIALS and RAW NANOVALUE), 3 national clusters (MHTC Magurele, ROHEALTH, PROECO-CBRNE).

IMNR has implemented a quality management system (ISO 9001:2015), an innovation management system (SR 13572:2016), and is accredited by RENAR for laboratory analyses.
