3D lasersko skeniranje, CAD / CAM i CNC tehnologije u zaštiti kulturne baštine / 3D Laser Scanning, CAD / CAM and CNC Technology in the field of Cultural Heritage
(Beograd: Univerzitet u Beogradu - Mašinski fakultet / Belgrade: University of Belgrade - Faculty of Mechanical Engineering, 2011)
Savremene tehnologije nalaze veliku primenu u oblasti zaštite kulturne baštine. Posebno interesantno polje odnosi se na izradu „beskontaktnih“ replika umetničkih i arheoloških predmeta, kao i na restauraciju oštećenih ...
Interaction of Mg enriched kaolinite-bentonite ceramics with arsenic aqueous solutions
(Elsevier, 2009)
Mg-enriched kaolinite–bentonite ceramics prepared in this work exhibited very porous and non-uniform structures, with grain sizes ranging from 1 to 20 μm. During the interaction of this ceramics with aqueous solutions of ...
The ωσ method: A new contactless comparison method for measuring electrical conductivity of nonferromagnetic conductors
(AIP Publishing, 1997)
A novel, very simple, eddy current method for measuring the electrical conductivity of nonferromagnetic conductors is described. This method is relative, i.e., we measure the ratio of conductivities of two samples of the ...
Heat capacities and thermodynamic functions of neodymia and samaria doped ceria
(Elsevier, 2021)
Doped ceria materials are ionic conductors currently under investigation for use in solid oxide fuel cells, catalysts, and other applications. We measured the heat capacity of several doped ceria samples from 1.8 K to 300 ...
Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis
(Royal Society of Chemistry, 2008)
Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. ...
Photoacoustic properties of softmagnetic amorphous Fe81B13Si4C2 ribbon
(Springer, 1998)
Photoacoustic properties of amorphous Fe81B13Si4C2 ribbons were investigated. The amplitude and phase photoacoustic spectra were measured as a function of the modulation frequency of an He–Ne laser beam. Thermal diffusivity ...
XRF and LIBS measuring on metal and ceramic laser-cleaned surfaces
(Budapest: International Measurement Confederation (IMEKO), 2016)
The use of lasers in the conservation of artefacts plays an important role since its posibilities of safe, efficient and efective cleaning on complex surfaces and wide range of materials. This paper presents the results ...
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.
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 ...
Ka integritetu umetničkog dela / Into protection of artwork integrity
(Novi Sad: Platoneum d.o.o., 2017)
Ovaj introduktivni esej objavljen u okviru naučne monografije „Umetnost i kriminal“ autorke dr Renate Samardžić, daje pogled na pitanje očuvanja integriteta umetničkog dela, iz perspektive 21. veka, u kontekstu novih ...
