The effect of Nb2O5 on crystallite growth during the sintering of SnO2 ceramics
(Chapman Hall Ltd, 2014)
Assessment of graphitized coal ash char concentrates as a potential synthetic graphite source
(Molecular Diversity Preservation International, 2020-11)
Coal ash char concentrates from four countries (Portugal, Poland, Romania, and South Africa) were prepared, characterised, and graphitized under the scope of the Charphite project (Third ERA-MIN Joint Call (2015) on the ...
Influence of pH on the incorporation and growth of Pb2CrO5 crystallites in silica matrix
(Springer, 2011-09-01)
Pb2CrO5 nanoparticles were embedded in an amorphous SiO2 matrix by the sol-gel process. The pH and heat treatment effects were evaluated in terms of structural, microstructural and optical properties from Pb2CrO5/SiO2 ...

Nucleation and growth of silver nanostructures onto HOPG electrodes in the presence of picolinic acid
(Elsevier Science, 2013-01)
Silver electrodeposition onto HOPG electrodes in the presence of picolinic acid (PA) has been studied by cyclic voltammetry and chronoamperometry. Changes in the nucleation and growth mechanisms, which are dependent on the ...
Zeólita Mordenita: um estudo sobre a formação e o tamanho dos cristais
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2018-01-30)
The assimilation of the way a zeolite is formed from an amorphous system and the control over size and morphology of the synthesis products are fundamental aspects for "zeolitic engineering". A system for the synthesis of ...
Electrical and optical characteristics of SnO2 thin films prepared by dip coating from aqueous colloidal suspensions
(1997-12-01)
Starting from aqueous colloidal suspensions, undoped and Nb5+ doped SnO2 thin films have been prepared by using the dip-coating sol gel process. X-ray diffraction results show that films are polycrystalline with crystallites ...

Influence of pH on the incorporation and growth of Pb(2)CrO(5) crystallites in silica matrix
(SPRINGER, 2011)
Pb(2)CrO(5) nanoparticles were embedded in an amorphous SiO(2) matrix by the sol-gel process. The pH and heat treatment effects were evaluated in terms of structural, microstructural and optical properties from Pb(2)CrO(5)/SiO(2) ...
