In this research work, silica nano-porous thin films were deposited on glass substrates by layer by layer method. The thin films were calcinated at various calcination temperatures (200, 300, 400, and 500 °C). The morphology, surface characteristics, surface roughness and hydrophilic properties of the thin films were investigated by field emission scanning electron microscopy, attenuated total ...
In this research, Schottky diode with Al-PANI/MWCNT-Au structure was fabricated using spin coating of composite polymer and physical vapor deposition of metals. For this purpose, a thin layer of gold was coated on glass and then composite of polyaniline/multi-walled carbon nanotube was synthesized and spin-coated on gold layer. Finally, a thin layer of aluminum was coated on polymer layer. The ...

Synthetic dyes comprise a large group of organic, organic salt and organometallic compounds which number in the thousands. Most individual dyes are assigned colour index (CI) numbers which helps to identify structure and properties as well as identity where a series of names have been used by the manufacturers for the same dye. Pigments are also listed and can be either organic or inorganic in ...
In this article, we investigate the redistribution of implanted As+ ion and effect of it on the rate of oxide growth during steam oxidation of Si wafers at 900oC. Our results show that a highly enriched, thin layer of Arsenic forms at the interface between the oxide and the underlying Si. Also, the oxidation rate was found to increase depending on the depth distribution and dose of the implant...
book through his lucid presentation of much technical data. The discussion of corrosive qualities of water is unusually thorough and explicit as is his discussion of the sanitary significance of impurities in water and on bacterial decomposition of organic matter in water. What might be considered to be a deficiency is the rather limited discussion of waterborne diseases. The liberal footnotes ...
tlc screening and evaluation of antioxidant, antibacterial activity of onopordon macrocephalum by bioautography methodonopordon known as scotch thistle is a medicinal plant of the asteraceae family that is widely distributed in europe and asia, also it has many valuable medicinal properties as hypotensive and antitumor. thin layer chromatography (tlc) is wildly used in natural product extract a...
Owing amongst other to its high electron mobility, fullerene C70, has been widely used as an electron transporting layer in organic solar cells. In this research, we report the use of C70 thin films as electron transport layers of planar perovskite solar cells (PSCs) using a conventional device structure. The thickness of the C70 layer has been optimized to achieve the best efficiency of 12%. I...
