Nikolaos Boukis is an expert in the field of supercritical water, corrosion and contact person for questions concerning the above mentioned topics and the fermentation of synthesis gases at high pressures.
Nikolaos Boukis studied chemistry at the University of Athens (NKUA) (1976-1981). He completed his doctorate at the Ruprecht-Karls-Universität Heidelberg in the fields of radiochemistry and physical chemistry (1985), with the experimental part taking place at the Nuclear Research Centre Karlsruhe, Institute for Hot Chemistry (IHCh, today KIT - IKFT). After his doctorate, he was called up for military service. During this time, he researched camouflage colors at the Greek National Defense Research Center (ΚΕΕΘΑ, until 1987). Subsequently, he worked and researched in the field of spent nuclear fuel reprocessing at the former IHCh. Since 1992 he has been in charge of application-oriented work in the field of supercritical water (in particular reactor material corrosion and biomass gasification) and since 2016 also in the field of microbial fermentation of synthesis gases under high pressure. From 2010 to 2012, he headed the project office for the construction of bioliq® plant components for gasoline synthesis and gas purification. Since 2016, Nikolaos Boukis is also IKFT's radiation protection officer (SSB).
