A detailed XRD and FTIR analysis of Bi2O3 doped ZnO-SnO2 ceramics
(A Global Road Map for Ceramic Materials and Technologies: Forecasting the Future of Ceramics, Intern, 2008)
ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures ...
Characterization of the structure and magnetic properties of Fe49Co2V made by the powder metal injection molding route
(Advances in Powder Metallurgy and Particulate Materials - 2010, Proceedings of the 2010 Internationa, 2010)
The semi-hard magnetic alloy Fe49Co2V is widely used in electronics and automation. Many of these parts are complex ones which can be produced with significant advantages by the PIM technology. In this work the feedstock ...
Fish Stock Management Cooperation in the Lower Danube Region: A Case Study of Sturgeons and Pontic Shad
(Springer, Dordrecht, 2012)
The Danube River is 2,857 km long and navigable along the major part of its flow (2,411 km). Human activities have started to influence Danube River flow more significantly since the sixteenth century, through the flood ...
Structural organisation of the wood polymers in the wood fibre structure
(China Light Industry Press, Beijing, 2011)
The organisation of the major polymers in the wood fibre structure has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, the structure providing ...
Characterization of ferrite surface mount bead using S-parameters
(SIISY 2010 - 8th IEEE International Symposium on Intelligent Systems and Informatics, 2010)
In this paper, characterization of ferrite surface mount bead based on S-parameters measurement, using vector network analyzer E5071B and specially developed PCB test fixture, are presented. The validation of characterization ...
A Characterization of Ceramic SMD Inductors for PCB Applications
(IEEE, New York, 2009)
In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a ...
Design of RFID antenna in ink-jet printing technology
(IEEE, 2012)
In this paper design of 125 kHz RFID antenna is presented. The optimization and improvement of electrical characteristics, including inductance and Q-factor, is also discussed. Designed RFID antenna is part of the ID card, ...
Sintered strontium hexaferrite shaped by injection moulding in unidirectional magnetic and electromagnetic field
(European Powder Metallurgy Association (EPMA), 2010)
Strontium hexaferrite permanent magnets were produced by powder injection molding (PIM). The feedstock for powder injection molding was prepared by mixing strontium hexaferrite powder with a "Solvent system" organic binder. ...
Development of fly ash-based geopolymer microstructure at room temperature
(Novpress Sro, Brno, 2011)
The development of geopolymers, as an alternative to traditional cement, by alkali activation of fly ash is a research topic in the scientific community. Many authors have agreed that there is a strong link between mechanical ...
MRI brain tumors images by using independent component analysis
(SISY 2011 - 9th International Symposium on Intelligent Systems and Informatics, Proceedings, 2011)
The magnetic properties of nuclei have significant applications in medical imaging. These applications are possible because the relaxation properties and the resonance frequency for a nucleus depend upon its environment. ...
