Ytterbium disilicate powders were synthesized by cocurrent chemical coprecipitation method. The influence of Si/Yb molar ratio and calcination temperature on compositions structures Yb2Si2O7 products investigated. formation mechanism thermal behavior precursor as well the phase evolution also discussed in depth. Results show that pure β-Yb2Si2O7 with nanoscale size can be obtained from 1.1 afte...

By adopting a simple cost effective microwave-assisted synthesis methodology, nanosized ceria-zirconia solid solution (MW) has been prepared. For comparison purpose, ceria-zirconia solid solution with the same composition was also synthesized by a coprecipitation method (CP) and calcined at 773 K. Both the samples were examined by different characterization techniques namely, X-ray diffraction,...

A simple and highly sensitive separation and preconcentration procedure, which has minimal impact on the environment, has been developed. The procedure is based on the carrier element free coprecipitation (CEFC) of Co(II), Cu(II), and Ni(II) ions by using 2-{4-[2-(1H-indol-3-yl)ethyl]-3-(4-methylbenzyl)-5-oxo-4,5-dihydro- 1H-1,2,4-triazol-l-yl}-N'-(pyridin-2-yl methylidene)acetohydrazide (IMOTP...

suitability analysis is a prerequisite for sustainable agricultural production and it involves evaluation of the environmental parameters. the development and creation of appropriate points for this land use without considering environmental capability will result in the appearance of several ecological, economic, and social problems. the multi-criteria decision making (mcdm) models were used f...

Titanium dioxide nanopowders doped with different amounts of Fe ions were prepared by coprecipitation method. Obtained materials were characterized by structural (XRD), morphological (TEM and SEM), optical (UV/vis reflection and photoluminescence, and Raman), and analytical techniques (XPS and ICP-OES). XRD analysis revealed rutile crystalline phase for doped and undoped titanium dioxide obtain...
