Mechanical and structural characteristics of atmospheric plasma-sprayed multifunctional tio2 coatings
(Materiali in Tehnologije, 2020)
Titanium dioxide (TiO2) is a multifunctional oxide that is an interesting material for many technological applications. This paper presents the mechanical properties and microstructure of TiO2 coatings resistant to dry ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Springer, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
Simulated Body Fluids Prepared with Natural Buffers and System for Active pH Regulation
(Iranian Institute of Research and Development in Chemical Industries, 2022)
The current study focuses on creating an initial highly alkaline simulated body fluid whose pH can be decreased to a physiological range by adding CO2 (protein-free simulated body fluid) or a combination of CO2 and human ...
Design of anti-tarnish sterling silver ag-cu-zn alloy and investigation of silicon addition influence on mechanical and corrosion characteristics / Dizajn legura sterling srebra Ag-Cu-Zn otpornih na tamnjenje i ispitivanje uticaja dodatka silicijuma na mehaničke i korozione karakteristike
(Association of the Chemical Engineers of Serbia, 2018)
This paper presents investigations of the influence of silicon addition on the mechanical and corrosion characteristics of the sterling silver Ag-Cu-Zn alloys. The procedure for obtaining Ag-Cu-Zn-Si alloys in small ranges ...
Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...
Immobilization of laccase from Trametes versicolor on Lifetech (TM) supports for applications in degradation of industrial dyes / Imobilizacija lakaze producenta Trametes versicolor na Lifetech (TM) nosače u cilju primene u razgradnji industrijskih boja
(Savez hemijskih inženjera, 2020)
In this study, immobilization of laccase from Trametes versicolor on eight Lifetech (TM) supports, with different characteristics (pore size, length of the spacer arm and functional groups), was studied and optimized for ...
Stimuli-Sensitive Hydrogel Based on N-Isopropylacrylamide and Itaconic Acid for Entrapment and Controlled Release of Candida rugosa Lipase under Mild Conditions
(Hindawi Ltd, London, 2014)
Stimuli responsive pH- and temperature-sensitive hydrogel drug delivery systems, as those based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), have been attracting much of the attention of the scientific community ...
Origin of the Intrinsic Coercivity Field Variations of ε-Fe2O3
(Russian Journal of Physical Chemistry A, 2019)
ε-Fe2O3 phase is recognized as an attractive material, in both technological and scientific point of view, since it can achieve very high room-temperature coercivity (10–20 kOe). In this paper, multi-phase samples Fe2O3/SiO2 ...
Origin of the Intrinsic Coercivity Field Variations and Magnetic Study of ε-Fe2O3
(Russian Journal of Physical Chemistry A, 2019)
Origin of the intrinsic coercivity field variations observed by hysteretic measurements established by Nikolic et al. was investigated in detail by ZFC/FC measurements. In this study, magnetic behavior of the samples is ...
Analysis of mechanical and structural properties of micro alloyed steel welded joints depending on quality of cored wire
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
The aim of this study was to master new quality cored wires made of steel strips and the cores filled with metal powders and low molecular hydrophobic compounds. For experimental research, the specimens were made of micro ...
