The effect of the mass ratio of hard and soft segments on some properties of thermoplastic poly(ester-siloxane)s
(John Wiley and Sons Ltd, 2004)
A series of thermoplastic elastomers based on soft polydimethylsiloxane (PDMS) and hard poly(butylene terephthalate) (PBT) segments was synthesized using a two-step transesterification reaction in the melt. The molar mass ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Optimisation of ferriferous dust and mud preparation acts from iron and steel production on purpose of returning to primary processes / Optimizacija postupaka pripreme železonosnih prašina i muljeva iz proizvodnje gvožđa i čelika u cilju vraćanja u primarne procese
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was ...
Fuel consumption analysis in cooper melting and refining plants / Analiza potrošnje energenata u pogonima za topljenje i rafinaciju bakra
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Cathode cooper production and refining include significant consumption of almost all-conventional fuel types. The given consumption is high in specific and in nominal way. Especially high fuel value content is on Cathode ...
Biaksijalna metoda igle za obrađivanje sposobnosti drapiranja tkanina od agroceluloznih vlakana / Biaxial pin method of determination the agro cellulose woven fabrics drape ability
(Savez inženjera i tehničara tekstilaca Srbije, 2004)
Razvijena je metoda za ispitivanje sklonosti tkanina ka drapiranju, nazvana metodom igle. Metoda se zasniva na oceni drapiranja uzoraka tkanih površina pravougaonog oblika. Metoda omogućava simultano određivanje faktora ...
Some important characteristics of woven fabrics / Neke bitne karakteristike tkanina
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2004)
In this paper characteristics of woven fabrics that might be of importance from the aspect of fabrics usage value are described. These characteristics are: thickness, area density, fabric cover, porosity, elasticity ...
Underpotential deposition of hydrogen on MoPt 4 intermetallic phase in acid solution: Temperature dependence
(Elsevier Ltd, 2004)
Potentiodynamic studies of the underpotential deposition of hydrogen (H upd ) on MoPt 4 electrode in 0.5 mol dm -3 HClO 4 aqueous solution in the range of temperature from 275 to 312 K are made and thermodynamic state ...
Heavy metals in petroleum-contaminated surface soils in Serbia
(Societa Chimica Italiana, 2004)
Investigation of heavy metal contamination levels as well as their association types with substrates in petroleum-contaminated surface soil was carried out using modified sequential extraction method. In that way, ...
One-dimensional random walk of nanosized liquid Pb inclusions on dislocations in Al
(Taylor & Francis, 2004)
Migration of nanosized liquid Pb inclusions attached to dislocations in Al
has been observed during in-situ transmission electron microscopy heating
experiments and monitored by real-time video recordings. The movements ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
