Two step sintering of the ZnTiO3 nanopowder
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Metastabile nanopowder ZnTiO3 pressed into cylindrical compacts at 200 MPa was submitted to conventional heating with isothermal holding at 931oC for 10 minutes, 25 minutes and 40 minutes. Same compacts were heated with ...
The Effects of Aggressive Environments on the Properties of Fly Ash based Geopolymers
(IOP Publishing Ltd, Bristol, 2015)
This paper analyzes the effects of two different aggressive environments, concentrated ammonium nitrate solution (480 g/dm(3)) and sodium sulphate solution (50 g/dm(3)), on the structure and mechanical strength of fly ash ...
Mehanizam gašenja fotoluminescencije u tankim filmovima N,N′-bis(3- methylphenyl)-N,N′-bis(phenyl)benzidine osvetljenih UV svetlošću u vazduhu / MECHANISM OF PHOTOLUMINESCENCE QUENCHING IN THIN FILMS OF N,N′-BIS(3- METHYLPHENYL)-N,N′-BIS(PHENYL)BENZIDINE IRRADIATED BY UV LIGHT IN AIR
(Savez inženjera i tehničara Srbije, Beograd, 2015)
U ovom radu je prikazana studija mehanizma gašenja fotoluminescencije (FL) tankih amorfnih filmova N,N'-bis(3-methylphenyl)-N,N'-bis(phenyl)benzidine (TPD) izloženih UV zračenju u vazduhu. TPD je organski molekul koji se ...
Cytotoxic effect of nanoceria on colon cancer cells (HT-29)
(Serbian Chemical Society, 2015)
Radiotherapy is commonly used for the treatment of colon cancer. Additionally, various antioxidant agents, such as nanoparticles of cerium oxide (nanoceria, nanoCeO2), are being investigated as the adjunctive therapy. CeO2 ...
Impact fragmentation of nanoscale projectiles at ultrahigh striking velocities
(Springer Nature, 2015)
Molecular-dynamics simulations of the
classic Taylor experiment are performed to investigate
some general trends of impact fragmentation at ultrahigh
striking velocities. The striking velocities of flatended,
monocrystalline, ...
Comparison of two alkali-activated systems: mechanically activated fly ash and fly ash-blast furnace slag blends
(Elsevier Science Bv, Amsterdam, 2015)
Poor reactivity of fly ash (FA) in alkali activation process can be improved either by mechanical activation of fly ash or by blending fly ash with more reactive material, such as blast furnace slag (BFS). Both options ...
Anticancer properties of nanoceria
(International Max Planck Research School for Molecular Biology in Gottingen, 2015)
CeO2 (nanoceria) is the most important rare-earth oxide, which application is rapidly emerging. These nanoparticles are potent free radical scavengers, due to coexistence of Ce3+ and Ce4+ ions and formation of oxygen ...

(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković” – National Institute of Republic of Serbia, University of Belgrade, 2015)
Rhinusa pilosa (Gyllenhaal) (Coleoptera, Curculionidae) induces galls in Linaria vulgaris Mill., Yellow or
common toadflax (Plantaginaceae). Gall is defined as atypical plant growth induced by host-specific organisms,
and ...
Characterization of soybean hull peroxidase immobilized on glycidyl methacrylate copolymers
(Serbian Plant Physiology Society, Institute for Biological Research „Siniša Stanković“, University of Belgrade, Bulevar despota Stefana 142, 11060 Belgrade, Serbia, 2015)
Toxic aromatic pollutants that are found in various industrial wastewaters pose a serious environmental threat. Current methods for phenol removal have certain disadvantages, such as low efficiency, high cost or generation ...
European white elm: potential for wetlands reforestation
(International conference Reforestation Challenges, 03-06 June 2015, Belgrade, Serbia, 2015)
The aim of this study was to investigate the potential of European white elm
(Ulmus laevis Pall.) for wetland reforestation across the Europe. For this purpose, seed
was collected from 13 maternal European white elm trees ...
