Diet of the Round Goby Neogobius melanostomus (Pallas, 1811) (Gobiidae) in the Danube and Velika Morava Rivers in Serbia
(Bulgarska Akademiya na Naukite, 2020)
Since the early 1970s the spread of the Ponto-Caspian gobiids along the Serbian part of the Danube River has been reported, mainly owing to the construction of dams and canals linking the larger rivers. The aim of our study ...
Electrostatically driven energy shift of molecular orbitals of benzene and nicotine in carbon nanotube gaps
(Springer, Dordrecht, 2021)
The requirement for controllable frontier orbital energy shift in single-molecule devices based on electronic (tunneling) transport yielded several rules for device design that lean on molecular level pinning to the ...
Nanocrystalline Zn2SnO4/SnO2: Crystal structure and humidity influence on complex impedance
(Springer, Dordrecht, 2020)
Nanocrystalline Zn2SnO4/SnO2 powder was obtained by a solid state reaction of ZnO and SnO2 nanopowders mixed in the molar ratio 1:1. The phase composition of the obtained powder was studied by XRD and Raman spectroscopy, ...
Anthropogenic Pressures on Watercourses of the Danube River Basin in Montenegro
(Springer, 2020)
The surface area of Montenegro’s portion of the Black Sea drainage basin is 7075 km2, or 0.9% of the entire basin, and is made up of the rivers Tara, Piva, Lim, Ćehotina and Ibar, and Lake Plav. The major polluters of ...
The effects of ionizing radiation on the structure and antioxidative and metal-binding capacity of the cell wall of microalga Chlorella sorokiniana
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The impact of ionizing radiation on microorganisms such as microalgae is a topic of increasing importance for understanding the dynamics of aquatic ecosystems in response to environmental radiation, and for the development ...
Isolation of high-quality RNA from recalcitrant leaves of variegated and resurrection plants
(Springer Heidelberg, Heidelberg, 2020)
Resurrection plant Ramonda serbica is a suitable model to investigate mechanisms of desiccation tolerance, while variegated Pelargonium zonale has been proven to serve as an excellent model for the metabolite allocation ...
Yugoslav utopia of sustainable city—the synthesis of living environment and social order
(Springer Nature, 2021)
Following the breakup with the Soviet model of socialism in 1948, the search for an authentic Yugoslav path offered a novel politico-cultural agenda that was promoted, among other, via new humane architecture and urban ...
A resonant single-frequency molecular detector based on adiabatically changing electric field
(SPIE, 2021)
During last decades many gas sensing mechanisms, based on different physical or chemical interactions with sensitive materials, have been developed, but the problem of precise analysis of gas mixtures still remains. New ...
Photosynthesis Enhancement in Maize via Nontoxic Orange Carbon Dots
(Amer Chemical Soc, Washington, 2021)
The sustained increase in leaf photosynthesis may increase crop yield. Due to many limitations, plants use much less photosynthetic capacity than is theoretically possible. Plant nanobionics investigates nanoparticle ...
Estimation of carbon dots amelioration of copper toxicity in maize studied by synchrotron radiation-FTIR
(Elsevier, Amsterdam, 2021)
Carbon dots are biocompatible and non-toxic nanoparticles with chemical affinity to some heavy metals. Human activities increase soil pollution with copper. Cu is an essential microelement in plants, but excess can induce ...
