Optical properties and plasmon – Two different phonons coupling in ZnGeAs2 + Mn
(Journal of Alloys and Compounds, 2013)
Optical properties of p-type Zn1−xMnxGeAs2 for 0 ⩽ x ⩽ 0.078 were investigated by Raman spectroscopy at room temperature. Phonons of ZnGeAs2 are experimentally determined and they are in excellent agreement with those ...
Possibilities for safe food production in relation to trace elements Ni and Cr in Sumadija and Valjevo region
(Ecological Movement of Novi Sad, Srbija, 2010)
Durability of alkali activated materials
(Institute for Multidisciplinary Research, University of Belgrade, 2015)
In the last decade, great scientific attention has been devoted to alkali activated materials, including geopolymers and other related materials. These materials are seen as promising alternative binders, with a possibility ...
Pedosequences on spilites
(Srpsko društvo za proučavanje zemljišta, Beograd, 2010)
Na planini Tumba u Južnoj Srbiji izdvojena su zemljišta na spilitiraa, specifičnom supstratu nastalom submarinskim utiskivanjem lave u nekonsolidovane škriljce. Ustanovljena je pedosekvenca koju čine litosol -regosol ...
Creating aperiodic photonic structures by synthesized Mathieu-Gauss beams
(Physical Review A, 2017)
We demonstrate a kind of aperiodic photonic structure realized using the interference of multiple Mathieu-Gauss beams. Depending on the beam configurations, their mutual distances, angles of rotation, or phase relations ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
Elliptical vortex necklaces in Mathieu lattices
(Physical Review A, 2018)
We demonstrate unusual kinds of discrete vortex beams, elliptical necklaces, realized by Mathieu photonic lattices. Varying the order of the Mathieu lattices and their ellipticity, we can control the shape and size of such ...
COMMERCIAL FISHERIES ON DANUBE IN SERBIA
(Poljoprivredni fakultet Univerziteta u Beogradu, Srbija, 2011)
Sadržaj mikroelemenata i teških metala u zemljištima opštine Krupanj
(Srpsko društvo za proučavanje zemljišta, Beograd, 2010)
U radu su prikazani podaci o osnovnim parametrima plodnosti zemljišta i sadržaju nekih mikroelemenata i teških metala (Zn, Mn, Fe, Cd, Ni, Cr, Pb) u zemljištima opštine Krupanj (sa ukupno 281 lokacije). Različiti prirodni ...
Surface optical phonon (SOP) mode in ZnS/Poly (methylmethacrylate) nanocomposites
(ELSEVIER, 2020)
The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic ...
