Andrei Kovalevsky (Kavaleuski) is a principal researcher at CICECO - Aveiro Institute of Materials (starting from July 2013). He obtained PhD in physical chemistry in 2002 from Belarusian State University, working on mixed ionic-electronic conductors (MIECs) for various energy conversion, chemical production and environmental monitoring applications, including oxygen permeation membranes and solid oxide fuel cells (SOFCs). This was followed by post-doctoral research at University of Aveiro (Portugal) and Flemish Institute for Technological Research (VITO, Belgium), with main emphasis on developing new concepts and approaches for oxygen-permeable membranes for partial oxidation of hydrocarbon feedstock. Working as a post-doc in Aveiro in 2010-2013, he diversified his research interests into the domain of technologies for direct electrochemical reduction of metal oxides and pyroelectrolysis process, including demonstration of the concept for iron pyroelectrolysis in magnesium aluminosilicate melts (supervision of one PhD thesis concluded in 2014), and electrolytic in-situ reduction of iron oxides and ferrospinels in alkaline medium (currently one PhD thesis work ongoing and one post-doc supervised). Another research activity contributed by AK in that period deals with design of functional porous ceramics for catalytic and separation applications, including processing of porous cellular ceramics through emulsification in alumina/spinel suspensions and hydrothermal functionalization of the pores (one post-doc supervised, one PhD thesis work and one research grant (MSc) ongoing).
In 2012 AK started a new direction in CICECO research, focused on oxide thermoelectrics as cheap and much less toxic alternatives to traditional thermoelectric materials. Prospective applications include conversion of the concentrated solar radiation or waste heat from automotive exhaust to the electrical energy. AK proposed new ideas for boosting thermoelectric performance in oxides, based on unique structural and electronic tunability of these materials by imposed external conditions and specific redox interactions in the crystal lattice. Another innovative approach involves application of unconventional techniques for processing oxide thermoelectrics such as laser floating zone method (electrical- and magnetic field assisted), in collaboration with Physics Department of University of Aveiro. Currently AK supervises or co-supervises two post-docs, one research fellow and one MSc student focused on thermoelectrics topic. Since 2014 ten papers on oxide thermoelectrics were published with overall ~100 citations up to now, including publications in Chem. Mater. (IF=9.47, doi: 10.1021/acs.chemmater.5b01389), J. Mater. Chem. A (IF=8.87, doi: 10.1039/c6ta09860f), J. Phys. Chem. C (IF=4.54, doi: 10.1021/jp409872e) and Phys. Chem. Chem. Phys. (IF=4.12, doi: 10.1039/c4cp04127e), in collaboration with Empa (Switzerland), University of Stuttgart (Germany) and University of Zaragoza (Spain). In second half of 2017-beginning of 2018 AK gave/was invited to give 3 invited talks on thermoelectrics topic at two international conferences and one workshop. Several proposals on thermoelectrics with UA/CICECO as an international consortium coordinator were submitted to highly-competitive M-ERA.NET 2015, 2016 and INTERREG SUDOE 2015 calls, including participation of industrial partners Martifer Solar / Voltalia (Portugal) and Apel Laser (Romania). The recent proposal on advanced TE materials submitted to 2017 FCT Call for SR&TD Project Grants (PI -AK) is supported by Bosch Termotecnologia (Portugal) and Voltalia (Portugal) companies, manifested their interest to the progress and outcome of the project.
AK co-authored ~115 SCI papers, with h-index of 30 and ~3100 citations (Scopus, as of January 2018), 5 book chapters and participated in more than 20 R&D projects, supported by European Commission and national funding agencies. Currently he acts as a PI of a project supported by the program of bilateral cooperation between FCT and DAAD, Germany (2017-2018). AK has been a regular referee for ~20 SCI journals, including Advanced Materials, Advanced Functional Materials, Chemistry of Materials, Journal of Membrane Science, Inorganic Chemistry, ACS Applied Materials & Interfaces. He participates in Editorial Board of Heliyon journal (Elsevier). Between 2015-2017 AK acted as a project proposals evaluator for ACS Petroleum Research Fund, Israel Science Foundation (ISF), The Research Council of Norway and M-ERA.NET programs. AK contributes to the educational process at University of Aveiro by teaching two practical courses (“Laboratories of Materials Engineering II” within Integrated Master´s Program in Materials Engineering (4h/week) and ”Materials of Mechanical Construction” within Integrated Master´s Program in Mechanical Engineering (4h/week)).
