Mission, Goals, Tasks and Main Research Directions of Engineering Institute of Membrane Technologies of Georgian Technical University

Mission of Engineering Institute of Membrane Technologies of Georgian Technical University is to implement multifunctional scientific-research, educational and innovative programs of interdisciplinary and critical directions, the uniqueness of which is conditioned by revealing the creative potential of the University, the Institute and the international scientific community. Goal of the Institute is to carry out multidisciplinary, interdisciplinary fundamental and applied researches for industrial implementation and development of nanotechnologies, based on allocations and grants allocated by budgetary, local and foreign scientific foundations. Provide scientific, educational, expert and consulting services to legal entities and individuals in the footsteps of dozens of existing critical technologies.

New nanomaterials, nanotechnologies and nanosystems created at the Institute have been introduced in the medical, energy and food industries of Georgia, which has been mastered worldwide in 15 developed countries, where it has been granted the status of state-level critical technology, as well as new materials, catalysis, genetic engineering and digital technologies. Tasks of the Institute: 1. Description - systematization of the latest informational data on membrane technologies according to the sector directions of Georgian economy on the basis of local, international publications, scientific-technological and internet databases. 2. Together with the University faculties, development of educational-scientific infrastructure of nanotechnology research for all three levels of University Teaching, which provides international level working environment for students within Bachelor's, master's and doctoral programs. 3. Implementation of scientific-research activities for creation, processing, regulation and industrial development of new innovative products of membrane nanotechnologies and nanosystems.

Main directions of the Institute's scientific-research activities:

Development and creation of science-intensive membrane nanotechnologies, Nanosystems and innovative polymer nanomaterials for the purpose of sustainable development of the state and ensuring a safe environment for human health, their study-scientific and industrial scale development implies the following scientific-research activities in the fields of critical technologies, defense, ecology, natural drinking and wastewater, medical, energy, agriculture, food industry, pharmaceutical: 1. Research and monitoring of modern aspects of study, scientific and innovation activities of membrane Sciences and industry according to the sector directions;
2. Experimental research, processing of new nanocomposition materials, processing and creation of micro-, ultra-, nanofiltration and reverse osmotic membranes;
3. Theoretical and experimental
