Cleaning of architectural bricks using RF plasma "Metallic Stains
RF Plasma is a glow discharge typically generated through using oxygen and hydrogen as the input working gas. In the current study the radio frequency (RF) hydrogen plasma (H2) is used for removing some metallic stains (iron and copper) which affected the historical brick surfaces in Prince Yousef Kamal place. Untreated and treated surfaces were evaluated by OLS, EDX-SEM & ... Read more

8.	The paint layers of mural paintings at Abydos temples - Egypt: A closer look at the materials used
The present study forms part of the research undertaken on the mural paintings from Abydos area in Egypt, and it is concerned with the identification of the materials used in the paint layers of these murals. The methods used in this purpose are optical microscopes (OM), scanning electron microscope with an energy dispersive X-ray unit (SEM/EDS), X-ray diffraction (XED), and ... Read more

α-Bi2O3 nanorods: synthesis, characterization and UV-photocatalytic activity
In this study, Monoclinic bismuth oxide nanorods (_α_-Bi2O3 NRs) were successfully synthesized by a simple one-step hydrothermal route using (water: ethanol) (1:1) as a mixed solvents at optimum conditions. The Bi2O3 nano-powder was characterized in detail by different techniques in terms of their structural, morphological, compositional, optical and photocatalytic properties. X-ray diffraction (XRD) analysis indicated that the as-synthesized Bi2O3 NRs ... Read more
