Thiazolidines and synthetic analoges: Synthesis, characterization and reactivity / Tiazolidini i sintetički analozi - sinteza, karakterizacija i reaktivnost
(Hemijski pregled, 2008)
Compounds containing 4-oxo-1,3-thiazolidine ring attract attention due to their chemical reactivity, biological activity and diverse application. Among them, 2-alkylidene-4-oxothiazolidines are of interest as precursors ...
Short history of aromaticity concept / Kratka istorija pojma aromatičnosti
(Hemijski pregled, 2008)
One of the most used concepts in modern chemical literature is concept of aromaticity. However, aromaticity, similar to some other very useful chemical concepts, cannot be quantified and directly measured. Hence, aromaticy ...

(Hemijski pregled, 2005)
The results of the probe investigation related to knowledge of some of the basic chemistry facts are presented in this paper. Our investigation has involved teachers, parents and pupils.
Observation of all-metal aromatic molecules / Revolucionarni pronalazak aromatičnih molekula sastavljenih samo od atoma metala
(Hemijski pregled, 2001)
Aromaticity is a concept invented to account for the unusual stability of an important class of organic molecules: the aromatic compounds. Here we report experimental and theoretical evidence of aromaticity in all-metal ...
'Types' of aromaticity / 'Tipovi' aromatičnosti
(Hemijski pregled, 2008)
The field of aromaticity continues to be controversial. The central theme of this controversy is the definition of aromaticity itself. Today, the proliferation of 'types' of aromaticity goes far beyond the conventional ...
Criteria for characterization of aromaticity / Kriterijumi za karakterizaciju aromatičnosti
(Hemijski pregled, 2008)
Because of the importance of aromaticity in chemistry, there have been many attempts to rationalize and quantify this property, and to derive a universal quantitative measure of it. However, because of its multiple ...
Resolved structure and selectivity mechanism of a potassium channel / Određena je struktura i otkriven mehanizam selektivnosti kalijumovog kanala
(Hemijski pregled, 2001)
Potassium Channels play a central role in the function of nearly every living cell. In the nervous system they govern the frequency of nerve impulses. The Potassium Channels are highly selective-perhaps as much as 10000:1 ...
