This paper deals with a synthesis of new ionising radiation attenuation composite material from Lu2O3 - Bi2O3 nanoparticles structure, that has never been described yet. The describes the preparation nano- and microparticles by three methods: self-combustion synthesis, solid-state method coprecipitation method. Polymer solution was prepared Polyvinyl Butyral. Afterwards, nanofibers were process...

The results of carbon dioxide reforming CH4 (model biogas) on catalysts prepared by solution combustion synthesis (SCS) and impregnation moisture capacity methods are presented. Investigation the activity synthesized from initial mixtures Co(NO3)2-Al(NO3)3-urea different compositions was carried out for production synthesis-gas, SCS traditional incipient wetness catalyst preparation were compar...

In this study nano-crystalline ZnO particles were synthesized by microwave-assisted solution combustion method. Zinc nitrate and urea were used as oxidizer and fuel, respectively. The effect of fuel to oxidizer (F/O) ratio on ZnO powder properties was investigated by using different urea/nitrate ratios. X-ray diffractometer, scanning electron microscopy and fourier transform infra-red were used...

a synthesis of doped ceria by combustion method is performed. two types of fuel such asurea and glycine is used to investigate the effect of fuel reactivity and reaction rate on themorphology of the resulted powders. thermo gravimetric analysis is carried out by (tg/dta,rigaku thermalplus tg 8120) to study the exo–endo temperature of as-received powder. thecrystalline phases are identified by x...

The recent developments and trends in combustion science towards the synthesis of nanomaterials are discussed. Different modifications made to conventional combustion approaches for preparation of nanomaterials are critically analyzed. Special attention is paid to various applications of combustion synthesized nanosized products. 2008 Elsevier Ltd. All rights reserved.

nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize zno/cuo nanocomposi...
