DPR analysis of microstructural evolution of ZnO ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
It is well known that, due to their specific properties, ZnO - based materials are frequently used in electrotechnics and electronics. Since these properties are very Much dependent on the microstructural state of material ...
The investigation of strong active sites of dealuminated Y-type zeolite by TPD of carbon monoxide
(Springer, Dordrecht, 2003)
The active sites of hydrogen-exchanged Y zeolite (HY) and dealuminated (HDY) zeolites are investigated by TPD of carbon monoxide. Only the high temperature TPD spectra of CO (T(M)approximate to620-690degreesC) were observed, ...
The effect of reversing current on the properties of copper and electrolytic copper powder. I. The morphology of powder particles
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The selective dissolution of copper dendrites during electrodeposition by reversing current was discussed and the effects on the morphology of copper powder particles were elucidated.
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
Flowability of electrolytic copper powder
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The surface structure of powder particles, which allows free flow of copper powder, was examined. It has been shown that a sufficiently dense surface structure which permits free flow will be obtained if apparent density ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
Alterations in amount of chlorophyll as indicator of resistance for Chenopodium album L. and Amaranthus retroflexus L. to atrazine
(Springer Heidelberg, Heidelberg, 2006)
Resistance in weeds, as a natural phenomenon or caused by herbicide application, is a major challenge for science and agricultural production. Nevertheless, a small number of plants is naturally resistant or has developed ...
Mathematical modeling of cell distribution in alginate microbeads
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Alginate is one of the mostly used hydrogels for cell entrapment aimed for applications in food industry, environmental engineering, pharmacy and biomedicine. One of the major parameters affecting cell viability and activity ...
Modeling of microenvironmetal restricted yeast cell growth within Ca-alginate microbead
(Minerva Biotecnologica, 2008)
Aim. A phase-field mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for ...
The effect of partial root drying on growth, quality of fruits and ions content on tomato (lycopersicon esculentum l.)
(Springer Heidelberg, Heidelberg, 2004)
