Random vibration movements of liquid nanosized Pb inclusions in Al
(Elsevier B.V., 2004)
Transmission electron microscopy has been used to study the behavior of liquid nanosized Pb inclusions in Al ribbons made by rapid solidification. In situ heating experiments carried out in the temperature range from around ...
Growth study of surfactant-mediated relaxed SiGe graded layers for 1.55-μm photodetector applications
(Elsevier Sequoia SA, 2000)
A systematic study of Sb sufactant-mediated relaxed SiGe graded layers has been performed. The results have been compared
with those of relaxed SiGe layers grown at high temperatures, showing that the Sb-mediated SiGe ...
ZP maize hybrids as a raw material for the bioethanol production / ZP hibridi kukuruz kao sirovina za proizvodnju bioetanola
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2009)
The interest in maize as an ethanol producing plant was caused by the energetic crisis and restored as early as the beginning of the 1970s. The production of bioethanol as a fuel has been expanding for the last ten years. ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Comparison of Hydroxyapatite Sorption Properties Towards Cadmium, Lead, Zinc and Strontium Ions
(Trans Tech Publications, 2005)
Apatites are well known matrix for heavy metal immobilization and remediation of
ground water and contaminated soils. In this work, capacities of different synthetic hydroxyapatite
(HAP) samples for Pb, Cd, Sr and Zn ...
The Modeling of Insulin Controlled Release Process From Fibrous Artificial Store
(Emerald Group Publishing Ltd., 2005)
In the past, insulin was frequently administered by hypodermic injection, as liquids forms. To avoid problems incurred through the utilization of the injectable route of insulin administration, new dosage forms containing ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier Sci Ltd, Oxford, 2004)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
Effect of different fermentation parameters on bioethanol production from corn meal hydrolyzates by free and immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Wiley, Hoboken, 2009)
BACKGROUND: Bioethanol produced from renewable biomass, such as corn meal, is a biofuel that is both renewable and environmentally friendly. Significant scientific and technological investments will be needed to achieve ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
