The structural, electrical and optical properties of spark plasma sintered BaSn1-xSbxO3 ceramics
(Elsevier, 2020)
Antimony doped barium-stannate dense ceramic materials were synthesized using spark plasma sintering technique out of mechanically activated precursor powders. The influence of various Sb concentrations (x =0.00 – 0.10) ...
Past studies and potential measures for rehabilitation of the shallow lake (Lake Ludas)
(Geographical Institute “Jovan Cvijić” SASA, 2020)
Lake Ludaš has been under a strong anthropogenic influence for a very long time, so the history of fruitful scientific investigation was very often connected with the evaluation of a human impact and potential rehabilitation ...
Optimization of injected radiotracer volume for flow meter calibration in closed conduits
(Warsaw, Poland : Instytut Chemii i Techniki Jądrowej, 2020)
In chemical processes it is of essential for flow in the process to be accurate and well defined.
Fluid velocity measurements are important for fluid flow quality performance in the systems.
This study focuses on ...
Application of Ni(II)-alumina Composites for Electrocatalytic Reduction of 4-nitrophenol
(International Institute for the Science of Sintering, Belgrade, 2020)
Nickel-alumina composites with various content of nickel were synthetized by sol-gel method. The characterization of samples was performed by diffuse reflectance spectroscopy and electrochemical impedance spectroscopy using ...
Applying concept of 3d printing concrete in wind tower construction / Primena koncepta 3d štampe betona u izradi vetrogeneratora
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Although a most prominent material in contemporary construction practice due to
its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a ...
What is the preferred geometry of sulfur–disulfide interactions?
(Royal Society of Chemistry, 2020)
Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations. Statistical analysis of the geometrical data from the ...
Chelate coordination compounds as a new class of high-energy materials: The case of nitro-bis(acetylacetonato) complexes
(MDPI, 2021)
The existence of areas of strongly positive electrostatic potential in the central regions of the molecular surface of high-energy molecules is a strong indicator that these compounds are very sensitive towards detonation. ...
How aromatic system size affects the sensitivities of highly energetic molecules?
(Royal Society of Chemistry, 2021)
Positive values of electrostatic potentials above the central regions of the molecular surface are strongly related to the high sensitivities of highly energetic molecules. The influence of aromatic system size on the ...
Geometrical and energetic characteristics of Se⋯Se interactions in crystal structures of organoselenium molecules
(Royal Society of Chemistry, 2021)
Non-covalent selenium-selenium interactions between selenium-containing organic molecules were studied in crystal structures from the Cambridge Structural Database and by high-level quantum chemical calculations. Se⋯Se ...
Study of noncovalent interactions using crystal structure data in the Cambridge Structural Database
(The International Union of Crystallography (IUCr), 2021)
In the recent review it was point out that the crystal structures in the Cambridge Structural Database (CSD), collected, have contributeto various fields of chemical research such as geometries of molecules, noncovalent ...
