Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
Non-conventional interactions in proteins containing porphyrine
(Society of Physical Chemists of Serbia, 2006)
The significant number of XH/TI interactions with Ti-system of five-membered pyrrole rings and six-membered chelate rings from porphyrin was found in crystal structures of proteins. There is a larger number of the interactions ...
Dismutacija NO u NO+ i NO- vrste katalizovana jonima gvožđa u prisustvu mokraćne kiseline
(Belgrade : Serbian Chemical Society, 2001)
U našim ranijim radovima utvrdili smo da pri izlaganju cerebrospinalne tečnosti (CSF) azot monoksidu in vitro dolazi do njegove dismutacije u NO+ i NO' vrste. CSF sadrži tzv "slobodno" gvoždje u mikromoiarnim koncentracijama ...
Change of water redox potential, pH and rH in contact with magnesium enriched kaolinite–bentonite ceramics
(Elsevier, 2008)
It was established that the addition of Mg to the mixtures of kaolinite and bentonite can provide clay compositions which, after
sintering at high temperatures, produce very porous ceramics with microcrystalline and ...
The effects of laser light interactions with materials of cultural heritage
(Belgrade: Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2009)
The effects of laser light and material interaction during the process of testing, processing and conservations of cultural heritage objects are very important concerning of the material characteristics preservation. Ruby ...
A Novel Access to Tetrahydro β-Carbolines via One-Pot Hydroformylation / Fischer Indole Synthesis: Rearrangement of 3,3- Spiroindoleninium Cations
(American Chemical Society (ACS), 2008)
The two component one-pot hydroformylation/Fischer indole synthesis sequence of 2,5 dihydropyrroles and phenyl hydrazines allows a facile and convenient access to tetrahydro-β-carbolines in moderate to good yields.
XPS study of the nickel oxidation state in the reduced (Ag)NiMg/SiO2 vegetable oil hydrogenation catalysts
(Society of Physical Chemists of Serbia, 2008)
Two series of (Ag)NiMg/SiO2 catalysts are synthesized on SiO2 support derived
from two silica sources: diatomite activated at 800oC (Series a; Mg/Ni=0.1 and
SiO2/Ni=1.07) and synthetic water glass (Series b; Mg/Ni=0.1 ...
Melt Rheology of Aliphatic Hyperbranched Polyesters
(Wiley, 2009)
Rheological behavior in melt of aliphatic hyperbranched polyesters (AHBP), synthesized using pseudo-one-step and one-step procedure, was investigated in this work. Three commercially available AHBP were also examined. ...
Nekonvencionalne interakcije u proteinima koji sadrže hem / Non-conventional interactions in proteins with the heme group
(Belgrade : Serbian Crystallographic Society, 2006)
For this study, the Protein Data Bank (PDB) Select October 2004 list of non-redundant protein chains (25% threshold version, 2485 protein chains and 388067 amino acid residues) was used to examine systematically the ...
Dinamičko-mehanička svojstva hibridnih magnetnih kompozitnih materijala sa polimernom matricom / Dynamic mechanical properties of hybrid magnetic composite materials with polymer matrix
(Универзитет у Београду, Технолошко-металуршки факултет, 2009)
Savremena istraživanja u oblasti razvoja magnetnih kompozitnih materijala na bazi Nd-Fe-B legura usmerena su u tri osnovna pravca: povećanje magnetne energije, odnosno optimizacija magnetnih svojstava, poboljšanje otpornosti ...
