Solidification of High Chromium White Cast Iron Alloyed with Vanadium
(Japan Inst Metals, Sendai, 2011)
Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M7C3 carbide and the matrix, but its content in carbide is considerably higher. ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(University of Belgrade, Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Electrochemical Polymerization of Aniline
(Rijeka : InTech, 2011)
In recent years, great focus has been placed upon polymer thin films. These polymer thin films are important in many technological applications, ranging from coatings and adhesives to organic electronic devices, including ...
Design of a polyaniline based biosensor electrode for glucose: A comparative study of two immobilized systems
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
The present study compares the results of two different methods employed for preparation of polyaniline based glucose biosensor with respect to enzyme loading, biosensing efficiency and potential stability. Kinetic analysis ...
Production of bioethanol from corn meal hydrolyzates / Proizvodnja bioetanola na hidrolizatima kukuruznog brašna
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Bioethanol produced from renewable agricultural recourses is currently the most promising biofuel. In a lot of developed countries in Europe and in USA the use of bioethanol as an alternative fuel or a gasoline supplement ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier Science Sa, Lausanne, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Micromechanical properties of composite systems consisting of electrodeposited nickel coatings on different substrates / Mikromehanička svojstva kompozitnih sistema formiranih elektrohemijskim taloženjem filmova nikla i bakra na različitim podlogama
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Fine-grained nickel and copper thin films were electrodeposited (ED) from self-made sulphamate and sulphate electrolytes, respectively, on different substrates. The substrates were single crystal silicon with two different ...
Influence of yarn structure on water vapor permeability of plain knitted fabrics / Uticaj strukture pređe na propustljivost vodene pare glatkih pletenina
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
Water vapor permeability is a critical parameter in textile fabric comfort evaluation as it represents the ability of the fabric to transfer perspiration coming out of the human body. Clothing materials with high water ...
Recent trends in bioethanol production / Novi trendovi u proizvodnji bioetanola
(Association of Chemical Engineers of Serbia, 2011)
The rapid depletion of the world petroleum supply and the increasing problem of greenhouse gas effects have strengthened the worldwide interest in alternative, nonpetroleum sources of energy. Bioethanol accounts for the ...
