SYNTHESIS AND CHARACTERIZATION OF CaTiO<sub>3</sub>Pr FILMS
Journal Title: Journal of Science And Arts - Year 2010, Vol 13, Issue 2
Abstract
This study related on the synthesis and characterization of coatings consisting of CaTiO[sub]3[/sub]Pr by sol-gel and electrochemical deposition techniques in different working conditions. An electrolytic bath containing salts of Ca, Ti and Pr, respectively and methyl alcohol has been used in order to prepare CaTiO[sub]3[/sub]Pr coatings over copper substrates. The surface morphology observed by means of scanning electron microscopy technique (SEM) showed various shapes crystallites onto copper substrates specified to CaTiO[sub]3[/sub]Pr complex. The structural analyses are carrying out by means of X-ray diffractometry (XRD) method. The XRD results reveal a mixture of crystalline phases of TiO[sub]2[/sub] and Pr particles due to the increasing of orientation degree of crystallites on specific crystallographic directions.

A NOTE ON RINGS
In this paper we have mainly obtained some properties satisfied by the invertible and complement elements of a ring R with unity. We obtained that the complement of an idempotent element in a ring is idempotent. We obtai...
