The new “Updated science-wide author databases of standardized citation indicators” has been released. It represents a database of over 100,000 top-scientists and provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator. Separate data are shown for career-long and single year impact. Scientists are classified […]
We are proud to announce that Dr Silvia Hristova, who defended her PhD thesis in our group last year, was awarded by The Union of Scientists in Bulgaria for best PhD thesis in 2020. The thesis of Silvia considers the possibility of using controlled proton transfer as an elementary process in the molecular machinery. The […]
We warmly congratulate Professor Katharina M. Fromm (University of Fribourg), collaboration partner over many years, on her Chemistry Europe award. The Chemistry Europe Fellows Program was established in 2015 (as the ChemPubSoc Europe Fellows Program). For the period 2018/2019, 37 European chemists were recognized for their outstanding support as authors, advisors, guest editors, referees as […]
The first international scientific conference on “Medicinal, aromatic and edible plants and by-products in their processing (MAEP & WASTE): Use and utilization for a sustainable and circular economy” was held on 09.09.2021 in Plovdiv, Bulgaria. The main topics covered were the numerous opportunities for the application of biologically active substances from essential oil crops, such […]
Two novel, 7-hydroxyquinoline based, Schiff bases have been synthesized and their spectral properties have been investigated by combined use of optical and NMR spectroscopy and theoretical DFT calculations. The results indicate that 8-((phenylimino)methyl)quinolin-7-ol exists as a mixture of enol and two keto tautomers in solution, while 8-(((pentarfluorophenyl)imino)methyl)quinolin-7-ol is presented as a single enol form. Upon […]
A comprehensive chemical profiling of 1,1,1,2-tetrafluoroethane (freon R134a) subcritical extracts from the main genotypes of oil-bearing roses, was performed by gas chromatography–mass spectrometry (GC/MS) and gas chromatography with flame ionization detection (GC-FID) in order to reveal the differences in their chemical composition. One hundred and three individual compounds were identified using GC/MS and their quantitative […]
