The openings of Copper converter in Sarcheshmeh Copper Complex in Iranis made of a heat resisting austenitic steel (Fe-25Cr-12Ni) and many failures have been reported. Understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. Samples of as-cast alloy and those taken from failed ones were examined. Optical Microscopy (OM), X-Ray Diffraction...

Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters (PM10, PM2.5), sulfur oxide and nitrogen oxide. The study area has affected by different ...

Abstract Cuprate superconductor Bi 2 Sr CaCu O 8+ δ (BSCCO) has been a promising candidate of coherent, continuous, and compact THz light source owing to its intrinsic Josephson junction (IJJ) inside the crystal structure. In this paper, we utilized BSCCO cross-whisker (CW) junctions produce emitter device using whisker crystals which can be easily obtained compared with single crystals. As res...

The formation energies of LiCoO 2 , LiNiO and LiMnO were calculated using a combination adequately selected Hess cycles DFT computations. Several exchange-correlation functionals tested PBE for solids...
