The disclosed transformation of pre-sputtered Ti films into nanoparticles via controlled thermal oxidation
Nanoparticles of TiO2 were successfully prepared from pre-sputtered Ti films using the controlled thermal oxidation. The effect of oxidation temperature on structural, morphological and optical properties in addition to photocatalysis activity of the sputtered films was tested and explained. Analysis of XRD and EDAX elucidated the enhancement in crystallization and oxygen content with the increase of oxidation temperature. SEM depicted ... Read more

Electric, thermoelectric and magnetic characterization of γ-Fe2O3 and Co3O4 nanoparticles synthesized by facile thermal decomposition of metal-Schiff base complexes
Using novel compounds for synthesis of metal oxide nanomaterials can tune their physical properties due to the associated variation in the shape, size and crystallinity. In this work, γ-Fe2O3 and Co3O4 nanoparticles were successfully prepared by a facile thermal decomposition route, employing [Fe(C32H22N4O2)]·2H2O and [Co(C16H11N3O4)].12">12H2O complexes, respectively as new precursors. The x-ray diffraction and high resolution transmission electron microscopy investigation ... Read more

1.	Influence of acrylic coatings and nano-materials on the interfacial, physical, and mechanical properties of limestone-based monuments “Amenemhat II temple as a case study”
The present paper covers the study of limestone consolidants based on acrylic polymer (Paraloid B-72), Ca(OH)2 nanoparticles (Nanolime) and the acrylic polymer mixed with Ca(OH)2 nanoparticles. The experimental study was conducted on limestone samples from El-Ashmunein archaeological area, Minia, Egypt. Some tests were done for studying the behavior of the consolidants used. The main goal of these tests was to ... Read more
