Thermal behaviour of some nonporous methacrylate polymers
(Society of Physical Chemists of Serbia, 2010)
Three nonporous methacrylate polymer samples were synthesized by suspension
polymerization, and subsequently investigated. The surface area and the surface
morphology of the spherical beads were examined by the BET method ...
Diffusion-based kinetic modeling of textile dye adsorption by porous copolymer
(Society of Physical Chemists of Serbia, 2012)
Macroporous glycidyl dimethacrylate and ethylene glycol dimethacrylate
copolymer functionalized with diethylene triamine, PGME-deta, was tested as
adsorbent for removal of Acid Orange 10 (AO10) and Reactive Black 5 ...
Galactic Structures from Gravitational Radii
(Galaxies, 2018)
We demonstrate that the existence of a Noether symmetry in f (R) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales. ...
Perrhenate sorption by amino-functionalized glycidyl methacrylate copolymer: investigation of rhenium as an analogue of radioactive technetium
(Society of Physical Chemists of Serbia, 2014)
In order to define the favorable conditions for radioactive technetium (99Tc)
uptake, the sorption behavior of its non-active chemical analogue rhenium
(
75Re) on amino-functionalized macroporous hydrophilic copolymer ...
Quantification of basic dyes adsorption onto mesoporous silica SBA-15 using image analysis software
(Belgrade : Institute of Technical Sciences of SASA, 2014)
Caesium-137 and potassium-40 in blueberry-based products on the market in Serbia
(RAD Centre, Niš, Serbia, 2018)
Synthesis of gold nanoparticles using aldehyde functionalized levan as reducing agent
(Society of Physical Chemists of Serbia, 2014)
In this work, gold nanoparticles (AuNPs) were synthesized in aqueous
solution by aldehyde functionalized microbial polysaccharide levan as a
reducing agent. Resulting nanoparticles were characterized by UV-Vis
spectroscopy ...
Natural and artificial radionuclides in moss samples from the region of Northern Greece / Prirodni i proizvedeni radionuklidi u uzorcima mahovina iz regiona Severne Grčke
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2017)
Terrestrial mosses obtain most of their nutrients directly from precipitation and dry
deposition, and they can be used for monitoring of airborne radionuclide depositions.
Ninetyfive samples of Hypnum Cupressiforme were ...
Просторна дистрибуција природних радионуклида мерена у Србији употребом биомонитора / Spatial distribution of natural radionuclides measured by the use of mosses
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2017)
Активност природних радионуклида је мерена у 217 узорака маховина Hypnum
cupressiforme које су сакупљене крајем лета 2015. године на комплетној територији Републике Србије са циљем да се установи просторна дистрибуција
...
Praćenje promene sadržaja urana u vodi za piće iz beogradskog vodovoda tokom višegodišnjeg perioda / Tracking changes of contents of uranium in water from Belgrade plumbing during multi-year period
(Београд : Институт за нуклеарне науке "Винча" : Друштво за заштиту од зрачења Србије и Црне Горе, 2017)
Uran je prisutan u površinskoj i podzemnoj vodi u rasponu koncentracija od 0,01 µg/dm3 do 1500 µg/dm3. Zbog mobilnosti njegovih rastvorenih jedinjenja, može se
u povišenoj koncentraciji naći i u čovekovom organizmu u kome ...
