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

Website conceptualization and administration: Erwan Rauwel

                                           Research overview


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 activities are presently partially funded by the EMÜ Bridge Funding (P200030VLVB) and Mobilitas+ grant (MOBJD1200).
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 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 2015-2023 EQUiTANT (TK134),
