The influence of coated nanoCeO2 on the phenol content in wheat and pea
(Faculty of Chemistry, Serbian Biochemical Society, 2017)
Introduction
The use of nanomaterials in various commercial products and industrial processes has increased. Although the application of nanoparticles has great importance, some of them can be risky to human health and ...
The methods for nanoceria’s coating in order to improve its solubility
(Scientific association for development and affirmation of new technologies, 2015)
CeO2 (nanoceria) is the most important rare-earth oxide and potent free radical scavenger, due to coexistence of Ce3+ and Ce4+ ions and formation of oxygen vacancies on its surface. These nanoparticles can collect reactive ...
Uticaj mikrobioloških đubriva na prinos različitih genotipova salate / Effect of microbiological fertilizers on yield of different lettuce genotypes
(Београд : Мегатренд универзитет Београд, Факултет за биофарминг Бачка Топола, 2018)
Салата (Lactuca sativa L.) је једногодишња биљка из фамилије Asteraceae која припада групи лиснатог поврћа. Циљ истраживања био је да се утврди утицај микробиолошких ђубрива на принос различитих генотипова салате. Изведени ...
Phosphorus deficiency is the major limiting factor for wheat on alluvium polluted by the copper mine pyrite tailings: a black box approach
(Springer, Dordrecht, 2011)
Failures of tailings dams have degraded large areas of agricultural alluvial soils worldwide, and concomitant soil pollution studies are abundant. Yet, the data on the actual effects of thereby imposed stresses on major ...
Donor-acceptor joint effect in barium titanate systems
(Elsevier Sci Ltd, Oxford, 2015)
Modified Pechini process was used to prepare nanopowders of barium titanate (BT) co-doped with different concentrations of niobium and manganese. Influence of dopants on the grain growth inhibition and microstructure ...
Primeri težnji za verodostojnim sagledavanjem ličnosti iz istorije nauke, obrazovanja i kulture / Examples of pursuits for reliable consideration of persons from the history of science, education and culture
(Centar za vizantijsko-slovenske studije Univerziteta u Nišu / Centre for Byzantine-Slavic Studies of the University of NišMeđunarodni centar za pravoslavne studije / International Center for Othodox StudiesCentar za crkvene studije / The Centre for Church Studies, 2019)
U radu su integrisana prošla i buduća istraživanja u vezi sa ličnostima koje su se nakon obrazovanja stečenog u evropskim univerzitetskim i naučnim centrima posvetile unapređenju nauke, obrazovanja i kulture u Srbiji. Trag ...
Tuning of BiFeO3 multiferroic properties by light doping with Nb
(Innovinc International, 2019)
BiFeO3, as one of few multiferroic perovskites, is distinguished by some drawbacks such as high leakage current,
low remnant magnetic polarization, high electric coercive field, and difficulties of pure phase synthesis ...
Cytostatics as emerging pollutants – is there a threat for aquatic invertebrates?
(University of Agriculture in Krakow, 2018)
Seeking for a better quality of life, consumption of pharmaceuticals is constantly increasing. Pharmaceuticals are designed to be more potent, degradation resistant, to affect protein targets at relatively low doses. Many ...
Comet assay – a sensitive method for detection DNA damage and primary monitoring of ecosystem pollution pressure
(Institute of Marine Biology, University of Montenegro, 2019)
Untreated municipal wastewaters are one of the major negative contributors on freshwater quality, and consequently on ecosystem balance. Some compounds such as pharmaceuticals, cosmetic products, etc. could be genotoxic ...
Nanocrystalline SnO2-Zn2SnO4 composite thick films applied as humidity sensors
(Belgrade : Institute for Multidisciplinary Research, 2019)
Starting ZnO and SnO2 nanopowders (<100 nm) were mixed in a suitable ratio and calcined at 1050 °C for 2 hours to obtain nanocrystalline SnO2-Zn2SnO4 composite powder. Structural characterization performed by X-ray diffraction ...
