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 ...
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 ...
Nickel doped titanate catalysts for photocatalytic hydrogen generation
(Belgrade : Institute of Technical Sciences of SASA, 2019)
This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with ...
Mechanical features of copper coatings electrodeposited by the pulsating current (PC) regime on Si(111) substrate
(Electrochemical Science Group (ESG), 2020)
Mechanical features of the Cu coatings produced by the pulsating current (PC) regime on Si(111)
substrate have been investigated. The Cu coatings were electrodeposited by varying duty cycle (15−50 %) and keeping the current ...
Morphology, structure and hardness of electrolytically produced copper coatings
(Sarajevo : Faculty of Science University of Sarajevo, 2022)
Influence of various parameters of electrodeposition, such as type of cathode, composition of the electrolyte and thickness of the coating, on morphology, structure and hardness of copper coatings has been investigated.
Comparison of possible improvements of a periodically operated adiabatic CSTR with inlet concentration modulation for different shapes of the forcing function
(10th World Congress of Chemical Engineering (WCCE10), Barcelona, Spain, 2017)
Deliberate periodic operations have been recognized as one way of process intensification for several decades. Special attention has been dedicated to possible improvements of chemical reactor performance through periodic ...
Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes
(MDPI, 2020)
Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single ...
The Balkan Macrophyte Index (BMI) for Assessment of Eutrophication in Lakes
(Sofia, Bulgaria : Prof. Marin Drinov Academic Publishing House, 2020)
Aquatic plants have long been used as indicators for nutrient enrichment in lakes. In the Mediterranean, however, the process of developing and intercalibrating macrophyte assessment methods for lakes has lagged behind ...
The role of surface defects in HOPG on the electrochemical and physical deposition of Ag / Uloga površinskih defekata na HOPG-u u elektrohemijskoj I fizičkoj depoziciji Ag
(Belgrade : Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
Numerical simulation of fluid-structure interaction between fishing wobbler and water
(Niš, Serbia : University of Niš, 2020)
This paper deals with modeling, discretization, and numerical analysis of the two-way fluid-structure interaction between a fishing wobbler and a water stream. The structural domain is an assembly of several bodies that ...
