Dr. Dimitar Stoychev is a Professor at the Institute of Physical Chemistry—Bulgarian Academy of Sciences. He graduated from the St. Petersburg Institute of Technology (Russia) in 1969, receiving a diploma in electrochemical engineering (MS degree). In the same year, he joined the Institute of Physical Chemistry at the Bulgarian Academy of Sciences in Sofia. He obtained his Ph.D. degree in 1980 from IPC BAS. In 2000, he received his D.Sc. degree from IPC-BAS on the basis of his doctoral dissertation entitled “Immersion Treatment of Aluminum and Electrodeposition of Copper Coatings with Definite Properties”. The research interests of D. Stoychev include the electrodeposition (initial and advanced stages of electrocrystallization) of metals and oxide layers, their structure and physico-mechanical properties, corrosion resistance, methods for chemical and electrochemical passivation, and protection of metal surfaces using environment-friendly chemical solutions, protective/decorative, and functional composite coatings. He has authored and coauthored more than 200 scientific papers and reports, and he is the holder of 29 patents.
