Level of soil endanger with detritimental substances on the border of ash disposal in the area Obrenovac
(Srpsko društvo za proučavanje zemljišta, Beograd, 2010)
Istraživanja predstavljena u ovom radu sprovedena su na delu površine Opštine Obrenovac, koja gravitira ka obodu deponija pepela. Proučeni su elementi plodnosti i zagađenja zemljišta. Na proučavanom području zastupljeni ...
Optical properties of CdS thin films
(Elsevier, 2013)
The properties of CdS thin films were investigated by applying atomic force microscopy (AFM), Raman and far-infrared spectroscopy. CdS thin films were prepared by using the thermal evaporation technique under base pressure ...
Vortex solitons at the interface separating square and hexagonal lattices
(Physics Letters A, 2015)
Vortex solitons at the interface separating two different photonic lattices – square and hexagonal – are demonstrated numerically. We consider the conditions for the existence of discrete vortex states at such interfaces ...
Palladium-copper bimetallic surfaces as electrocatalysts for the ethanol oxidation in an alkaline medium
(Elsevier B.V., 2023)
Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified
with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C),
and ...
Methods for Assessment of Background Limit of Ni and Cr in Soils of Eastern Serbia
(Novi Sad : Institut za ratarstvo i povrtarstvo, 2011)
The primary objective of the present study was to point out different approaches to background limits assessment. The content of selected trace elements is relatively low, and elements have
right-skewed asymmetrical ...
Therapeutic potential of low-molecular weight lignin model polymer fractions for treating skin lesions in animals: a pilot study
(Springer Nature, 2023)
Bacterial infections and resistance to antibiotics are increasingly severe problems. In recent years, Staphylococcus species
have emerged as important pathogens in animals and humans. Current therapeutic methods against ...
Cascade luminescence and antibacterial behavior of fluorapatite nanopowder co-doped with Pr3+, NO3− and CO32− ions
(Springer, 2023)
In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-
nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated.
Uniform nanopowders were synthesized ...
Synthesis and characterization of luminescent Cu2+–doped fluorapatite nanocrystals as potential broad–spectrum antimicrobial agents
(Elsevier, 2023)
Nanomaterials based on metal–doped fluorapatite (FAP) have attracted considerable interest as potential
next–generation antimicrobial agents. In this study, Cu2+–doped FAP nanocrystals have been successfully synthesized
by ...
Altered state of primordial follicles in neonatal and early infantile rats due to maternal hypothyroidism: Light and electron microscopy approach
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
tThyroid hormones (TH) are one of the key factors for normal prenatal development in mammals. Previ-ously, we showed that subclinical maternal hypothyroidism leads to premature atresia of ovarian folliclesin female rat ...
Spatiotemporal instabilities of counterpropagating beams in nematic liquid crystals
(Elsevier, 2008)
We investigate the behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals. We treat numerically a time-dependent model for the beam propagation and the director reorientation in a ...
