The use of manganese(II)-pyromellitate complex precursor for the synthesis of nanosized manganese oxides
(Belgrade : Institut za multidisciplinarna istraživanja, 2022)
The increasing interest for nanosized mixed metal oxides such as spinels and
spinel-based materials in last decades has been motivated by their wide applications
in photocatalysis, magnetism or solar cells [1]. So far, ...
Influence of material surface roughness on backscattering in laser scanning
(Faculty of Architecture, Civil Engineering and Geodesy, University of Banja Luka, 2022)
In this paper, the possibility of applying Kirchhoff 's scalar approximation model for determining the backscattering coefficient from rough surfaces is investigated. Surfaces of dielectric and metallic materials, which ...

Procena ekotoksikološkog rizika veštačkih zaslađivača saharina i sukraloze u rečnoj vodi na teritoriji Beograda
(Beograd : Srpsko hemijsko društvo, 2022)
Veštački zaslađivači saharin i sukraloza predstavljaju emergentne zagađujuće materije čije prisustvo u akvatičnim ekosistemima može negativno uticati na osetljive organizme. Veoma su postojani u životnoj sredini, a posebno ...
BIOBASED COMPOSITE MATERIALS OBTAINED FROM UNSATURATED POLYESTER RESINS AND WASTE COFFEE
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS) Društvo za procesnu tehniku, Beograd, Srbija, 2022)
Replacing styrene with biobased monomers to produce fully biobased unsaturated polyester
resins (UPRs) turned out to be quite a challenging task. Styrene has been recognized as a hazardous
and a potentially carcinogenic ...
