Nanoparticles and nanocomposites applied to targeted applications sustainable energy, water remediation, and biomedical applications

Website conceptualization and administration: Erwan Rauwel

Research overview:

Sustainable energy, climate change mitigation, water remediation, and biomedical applications

 

Our research activities are in the frame of 5 UN sustainable development goals: Good health and well being, Cleaner water and sanitation, Affordable and cleaner energy, Climate actions, and Partnership for the goals. Our projects objectives fall in EU-decarbonized energy transition of 2050, and EU Green Deal principles of sustainability and green industry by promoting reusability of new technology and circular economy. Our research team regroups PhD students, researchers and professors from Estonian University of Life Science and Estonian Aviation Academy. Our main goal is to develop solutions based on nanotechnology to present societal problems related to climate change, energy and water scarcity and health.

 

Our research activities are presently mainly funded by the ETAg TEAM Grant (PRG2115), Thematic research and development programs from Estonian Ministry of Research / ETAg (TEM-TA144) and Mobilitas+ grants (MOBJD1200 and MOBJD1204).
We are a material science and nano-engineering research group with the main research focus on metal oxide and metal nanoparticle synthesis. Our research group is more particularly interested by silver, cobalt, copper, copper nitride, zinc oxide, hafnium dioxide, and hybrid nanomaterials. The main targeted applications are sustainable energy, biocidal coatings, water purification, optoelectronics, photovoltaics, photocatalysis, decrease of air freight carbon footprint, and biomedical application.

 

In addition to the conventional synthesis methods, green synthesis is an objective of ours. Team main expertise includes also thin film synthesis (ALD, MOCVD, PLD, sputtering), sol-gel chemistry, transmission electron microscopy and related techniques, vacuum techniques, CMOS technology, photoluminescence, scientific writing, research projects.

Our research activities were partially funded by the Estonian Centre of Excellence EQUiTANT TK134 (2015-2023) and EMÜ Bridge Funding (P200030VLVB) (2020-2023).
