个人简介
- Dr. Oleksandr Tkach is a researcher at the CICECO - Aveiro Institute of Materials, Department of Materials and Ceramic Engineering, University of Aveiro. He works in the field of Materials Science & Engineering and Solid State Physics. A particular area of his scientific activity is related to oxide electroceramics. Present research interests of Dr. Tkach include the development of thermoelectric and piezoelecric oxide materials and composites for energy harvesting technologies; giant permittivity dielectric oxides for energy storage; nanostructured magnetoelectrics for sensor and electronic applications; and alternative energy efficient concepts for current assisted ceramic sintering.
- Oleksandr Tkach graduated in Microelectronics and Semiconductor Devices by the National Technical University of Ukraine “Kyiv Polytechnic Institute” in 1999, investigating nanocrystalline silicon for optoelectronic applications.
In 2005 he got PhD degree in Materials Science & Engineering from the University of Aveiro, Portugal, studying strontium titanate based ceramics for tunable device applications under a personal PhD grant by Portuguese Foundation for Science and Technology (FCT).
Completion of PhD was followed by an award of Experienced Research position within Marie Curie research training network MULTIMAT to be realized by Dr. Tkach at the University of Barcelona. However, being Ukrainian citizen not supported in obtaining Spanish work visa, he had to return to Aveiro for 1.5 year post-doctoral fellow on multiferroics investigation, participating in EU FP6 STREP project MULTICERAL and European Network of Excellence FAME and contributing to 2 invited talks.
In 2007 Dr. Tkach won a personal post-doctoral grant by FCT to work at the University of Porto on alkali tantalates and other perovskite ceramics and thin films, contributing to 2 FCT I&D projects and to awarded poster done within bilateral Portugal/Germany project.
In 2012, he got post-doc contract at the Johannes Gutenberg University of Mainz, Germany, within EU FP7 project IFOX and ERC project MASPIC, investigating artificial multiferroic heterostructures and contributing to the photoemission-electron-microscopy synchrotron beam-times.
In 2014 Dr. Tkach was promoted to Assistant Researcher position in the University of Aveiro, CICECO, coordinating FCT Independent Researcher project, acknowledged in his 26 papers, 4 book chapters and 10 invited talks and used for hiring 2 post-doc fellows with Dr. Tkach as a solely supervisor for them as well as for 1 Master student. There are more 8 Master and 1 post-doc co-supervisions by Dr. Tkach. Besides being the FCT and CICECO internal projects PI, Dr. Tkach participated in 2 COST action TO-BE and NETPORE, more 3 FCT I&D projects; contributed to organization of 4 scientific events and to 1 awarded poster; edited a book published by Nova Science Publishers; joined Editorial boards of 6 scientific journals, reviewing as well manuscripts for >50 journals. In overall, Dr. Tkach has participated in 3 European, 8 Portuguese FCT and 2 projects with industry as well as 2 bilateral projects with aggregate amount over 48 M€.
- Dr. Tkach publication profile contains 1 edited book, 7 book chapters and 107 articles, including papers in high impact factor (IF) Advanced Functional Materials (IF=19.924), Nature Physics (IF=19.684), Journal of Materials Chemistry A (IF=14.511), Carbon (IF=11.307), Chemistry of Materials (IF=10.508) and Journal of Materials Science and Technology (IF=10.319). From his 47 publications in the top quartile JCR SCI journals in their areas, 20 papers are published in the in the top 5 journals of their areas. Four publications by Dr. Tkach in J. Eur. Ceram. Soc. 37 (2017) 2391, Coatings 8 (2018) 449, Nanomaterials 11 (2021) 1240 and C 8 (2022) 12 were highlighted as the feature or editor choice articles, one in J. Mater. Chem. C 6 (2018) 2467 was selected for the 2018 HOT Papers themed collection, and two in Phys. Rev. Lett. 101 (2008) 165704 and Condens. Matter 5 (2020) 58 were selected for reproduction in book “100 Years of Ferroelectricity 1921 – 2021” by World Scientific. Dr. Tkach is first author, lead writer, and principal contributor on 48/3 and corresponding author on 35/3 papers/chapters. According to Web of Science/Publons and Scopus, his h-index is 25 to date. According to Google Scholar (profile Alexander Tkach), there are about 2500 citations with h-index of 28.
