Ion/surface collisions: An alternative to gas-phase collisional activation in mass spectrometry
(Serbian Chemical Society, 2001)
Collisions of ions at solid surfaces result in a number of phenomena, of which surface-induced dissociation (SID) is the most important. SID has been shown to be a viable alternative to collision-induced dissociation (CID) ...
Štetne supstance i njihovo uklanjanje iz mase papira i voda kružnog toka / Harmful substances and their removal from paper pulp and and circular water stream
(Association of Chemical Engineers of Serbia, 2008)
U okviru ovoga rada dat je sistematski pregled uzroka intenzivnog povećanja sadržaja
štetnih supstanci u masi papira i vodama kružnog toka u poslednjih dvadesetak godina i
njihov negativan uticaj na proizvodnost papir ...
The effect of the composition of the dispersing medium of oxide sols on the electrocatalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes / Uticaj sastava disperzne sredine oksidnih solova na elektrokatalitičku aktivnost RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
Primary and secondary dendrite spacing of Ni-based superalloy single crystals
(Serbian Chemical Society, 2009)
Ni-based superalloy single crystals were grown by different methods (gradient method and Bridgman technique with spontaneous nucleation and with seed). In all crystal growth experiments using the Bridgman technique, the ...
Oxygen reduction at platinum nanoparticles supported on carbon cryogel in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2007)
The oxygen reduction reaction was investigated in 0.1 M NaOH solution, on a porous coated electrode formed of Pt particles supported on carbon cryogel. The Pt/C catalyst was characterized by the X-ray diffraction (XRD), ...
Performances of continuous dryer with inert medium fluidized bed / Performanse kontinualne sušnice sa fluidizovanim slojem inertnih čestica
(Association of Chemical Engineers of Serbia, 2008)
A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder. IV. The internal structure of the powder particles
(Journal of the Serbian Chemical Society, 2004)
The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, ...
The influence of some factors on the electrical conductivity and particle size of core/shell polystyrene/polyaniline composites / Утицај неких фактора на електричну проводљивост и величину честица композита са језгром од полистирена и омотачем од полианилина
(Serbian Chemical Society, 2005)
The electrically conductive, micron-sized, core/shell polystyrene (PS)/polyaniline (PANI) composite particles were synthesized by chemical oxidative polymerization of aniline in the presence of micron-sized PS particles ...
Analitičke tehnike za određivanje i praćenje hemijskih supstanci od uticaja na koroziju / Analytical technics for determination and monitoring of chemichal sustances affecting the corrosion
(Society for Structural Integrity and Life (DIVK), 2007)
Hemijske supstance u korozijskim naslagama i vodi i
pari u kontaktu sa naslagama već godinama izazivaju veliku pažnju svih onih koji su na bilo koji način povezani sa zaštitom materijala od korozije.
Population doses from terrestrial gamma exposure in Serbia
(Institute of Oncology, 2007)
Background: Terrestrial radiation emitted from naturally occurring radionuclides, such as 40K and radionuclides from the 238U
and 232Th series and their decay products represent the main external source of irradiation to ...
