Influence of V and N on Transformation Behavior and Mechanical Properties of Medium Carbon Forging Steels
(Trans Tech Publications Ltd, Durnten-Zurich, 2010)
The influence of vanadium and nitrogen on microstructure and mechanical properties of medium-carbon steels has been studied by means of metallography and mechanical testing. Vanadium addition to the low nitrogen steel ...
One-step synthesis of NIR-responsive NaYF4:Yb,Er"Chitosane nanoparticles for biomedical application
(Belgrade : Institute of Physics Belgrade, 2017)
There is a great technological interest in synthesis of lanthanide doped upconverting nanoparticles with specific morphological characteristics and efficient luminescence response suitable for biomedical use [1]. A ...
The effect of Ni content on passivation of copper anodes with non-standard chemical composition
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes ...
Microindentation hardness testing of different composite systems with thin electrodeposited nickel and copper films
(Belgrade : Military Technical Institute, 2012)
Thin Ni and Cu films with fine-grained structures have been electrodeposited from self-made sulphamate-based and sulphate-based electrolytes, respectively. DC electrodeposition of Ni films was performed on single crystal ...
Novel membrane adsorbers incorporating cross-linked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid)
(Belgrade: Institute of Technical Sciences of SASA, 2013)
Membrane adsorption has started to replace fixed bed chromatography for separation and purification of small quantities of valuable species in biotechnology and related areas. Membrane functionalization is usually required ...
Novel negatively-charged ultrafiltration membranes made by a combination of immersion precipitation and photopolymerization
(Belgrade : Serbian Chemical Society, 2013)
Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity ...
The influence of current density on charge/discharge characteristics of polyaniline electrode
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
Polyaniline (PANI) was electrochemically synthesized on graphite electrode galvanostaticaly from aqueous solution of 0.25 mol dm-3 aniline and 0.5 mol dm-3 p-toluenesulfonic acid. Charge capacity available for the exchange ...
Technological analysis for machining of the reformers for fuel cells testing
(Innovation Center of Faculty of Mechanical Engineering, 2017)
Reformer is an integral component of the polymeric electrolyte membrane (PEM) fuel cell and it is used for
experimental combustion testing. By analyzing the geometry of the experimental reformer, it consists of three
plates, ...
Study of lipase-catalyzed synthesis of ascorbyl oleate using response surface methodology
(6th Central European Congress on Food, CEFood 2012, 2012)
L-ascorbic acid has good antioxidative properties but its efficiency in stabilizing fats and oils in products with high lipid content is negligible due to its hydrophilic characteristics. On the other hand, fatty acid ...
