Particle-induced x-ray emission spectrometry of size-fractionated atmospheric aerosols
(4th International Yugoslav Nuclear Society Conference - YUNSC, 2002)
Atmospheric aerosol samples were collected with a stacked filter unit (SFU), which
separates the aerosol into a coarse (2-10 µm aerodynamic diameter (AD)) and a fine (< 2
µm AD) size fraction. The samples were analysed ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder / Procena međupovršinske energije bakar-rastvor bakar sulfata i specifične površine bakarnog praha
(Serbian Chemical Society, 2002)
Apossible way for the estimation of the interfacial energy of the copper – copper sulphate solution interface is proposed. The estimated value of (2.7±0.3) J cm-2 and the derived equations which relate the specific surface ...
Reflection and structural characteristics of semi-bright and mirror bright nickel coatings
(Journal of the Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening, addition agent arc examined. It is shown ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
The influence of electroless plated chromium on printing properties of aluminum offset printing plate
(Journal of the Serbian Chemical Society, 2002)
A method for the improvement of the printing properties of offset printing forms is presented. Specimens of technical aluminum were electrochemically roughened and treated in different alkaline solutions of chromium chloride ...
Influence of plying on singles hemp yarn properties / Uticaj končanja na svojstva pređa od konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2002)
The return to garments that provide the maximum of natural properties became a new trend contributing significantly to environmental protection. In this situation hemp as a historical and controversial fiber gained the new ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Complex evaluation of elastic characteristics of clothing wool fabrics by 'DA Q XIAO q' method / Kompleksna ocena elastičnih karakteristika vunenih odevnih tkanina 'DA Q XIAO q' metodom
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2002)
Chinese method "DA Q XIAO q" is applied on 18 samples of clothing wool fabrics made in three variants of weaves (plain, twill 2/2, cross-twill) aimed at establishing the complex evaluation of elasticity of investigated ...
Neke metode i uređaji za ispitivanje jednocikličnih i višecikličnih karakteristika tekstilnih materijala pri dejstvu aksijalnih sila / Some methods and devices for investigation of textile materials behavior under occurring once and repeated action of external axial forces
(Savez inženjera i tehničara tekstilaca Srbije, 2002)
Razmatrane su neke metode i uređaji za ispitivanje ponašanja tekstilnih materijala pri jednostrukom i višestrukom dejstvu spoljašnjih aksijalnih sila čiji je intenzitet manji od prekidnog. U radu su prikazani različiti ...
