Assessment of density functional approximations for calculation of exchange coupling constants in thiocyanato and cyanato double bridged binuclear Ni(II) complexes / Испитивање апроксимативних функционала густине за израчунавање константи купловања у двоструко премошћеним тиоцијанато и цијанато бинуклеарним Ni(II) kомплексима
(Belgrade : Serbian Chemical Society, 2020)
In the present work, we examine the magnetic properties of 8 "end-to-end" thiocyanato, and 3 "end-to-end" cyanato double bridged Ni(II) binuclear complexes. Thiocyanato complexes are weakly ferromagnetic. Cyanato bridged ...
Photocatalytic hydrogen evolution over surface-modified titanate nanotubes by 5-aminosalicylic acid decorated with silver nanoparticles
(Elsevier B.V. and The Society of Powder Technology Japan, 2020)
The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed ...
Dynamic stability of active sites in hydr(oxy)oxides for the oxygen evolution reaction
(Springer Science and Business Media LLC, 2020)
The poor activity and stability of electrode materials for the oxygen evolution reaction (OER) are the main bottlenecks in the water splitting reaction for H2 production. Here, by studying activity
stability trends for ...
Thermal and microstructural analysis of the low-melting Bi-In-Pb alloy
(Association of Metallurgical Engineers of Serbia (AMES), 2020)
Low-melting alloys, based on bismuth and indium, have found commercial use in soldering, safety devices, coatings, and bonding applications. In this respect, the accurate knowledge of their thermal properties such ...
Characterization of carbon fibrous material from platanus achenes as platinum catalysts support
(Serbia : Association of Metallurgical Engineers of Serbia, 2020)
Carbon materials with developed porosity are usually used as supports for platinum catalysts. Physico-chemical characteristics of the support influence the properties of platinum deposited and its catalytic activity. In ...
Optimization of microbial fuel cell operation using Danube River sediment
(Elsevier, 2020)
One of the main global focuses of mankind today is the required switch to new energy sources. Generating energy from waste is one of the potential solutions that can be achieved using microbial fuel cells (MFCs). Microorganisms, ...
Resonant coaxial SMA microwave permittivity sensor
(Walter de Gruyter GmbH, 2020)
Resonant coaxial SMA microwave permittivity sensor is introduced. It is constructed using only commercially available SMA connectors. The sensor is tested in two different frequency ranges for two different dielectric ...
A water quality assessment based on benthic diatoms of the timok river basin (Eastern Serbia) under multiple anthropogenic pressures
(Academic Publishing House, 2020)
The study is focused on diatom communities as indicators of the water
quality of aquatic ecosystems. The study included watercourses of the Timok
River Basin in eastern Serbia. Sampling of algological material and ...
Comparative analysis of length differences between georeference surfaces
(England : Taylor and Francis Ltd., 2020)
The article deals with the length differences between georeferencesurfaces within the state coordinate system of Serbia. It’s ananalysis starting from the topography, through geoid and ellipsoid,to the map projection. ...
Genetic and morphological variation in Chara contraria and a taxon morphologically resembling Chara connivens
(Taylor & Francis, 2020)
Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. ...
