Influence of oxygen reduction on the structural and electronic properties of electron-doped Sr1−xLaxCuO2 thin films
(Elsevier B.V., 2009)
Single-phase, c-axis oriented, e-doped, Sr1−xLaxCuO2 thin films were epitaxially grown on KTaO3 and DyScO3 substrates by reactive rf sputtering. As-grown films being insulating due to oxygen excess, oxygen reduction is ...
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 ...
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 ...
Wavelets and stochastic theory: Past and future
(Elsevier, 2023)
In the paper, authors report on the interdisciplinary and extremely complex link between wavelets and stochastic processes. An insight into the history of wavelets has been provided presenting the fundamental conception ...
Control of Airy-beam self-acceleration by photonic lattices
(Physical Review A, 2014)
We demonstrate control over the acceleration of two-dimensional Airy beams propagating in optically induced photonic lattices. Depending on the lattice strength, we observe a slowing-down and suppression of the self-acceleration ...
Albumin at the intersection between antioxidant and pro-oxidant in patients on peritoneal dialysis
(Elsevier, 2022)
Albumin (HSA) is a multifunctional protein and due to its free Cys34 thiol group, represents a main source of free
thiols in the circulation. This property of HSA, combined with its ability to sequester redox active Cu(II) ...
Stanje i pravci razvoja materijalno-tehničkih aspekata sredine za učenje/nastavu hemije u beogradskim osnovnim školama
(Beograd : Savez pedagoških društava Jugoslavije, 2013)
Теоријска разматрања и емпиријска истраживања указују да је средина за учење/наставу важан фактор за реализацију наставе високог квалитета. Параметри за уређење средине за учење/наставу хемије у Републици Србији стандардизовани ...
Security Enhancement of Joint Procedure Based on Improved Elliptic Curve Cryptography in LoRaWAN
(Spreinger Wireless Personal Communications, 2023)
For long-range communication, Long-Range Wide Area Network (LoRaWAN) is the appropriate media access layer protocol. This LoRaWAN protocol connects the end devices and the application server through the gateways. The end ...
