The performance of LaMnxNi1-xO3±δ perovskite mixed oxides (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) which were prepared by different methods, the Pechini and sol-gel methods in the oxidation of greenhouse gases, CH4 and CO, has been investigated. All samples were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electr...

The proposed work describes the algorithms for Image Compression using Transform Coding Methods: Modified Hermite Transform (MHT), Discrete Cosine Transform (DCT) and Wavelet Transform (WT).In MHT and DCT, the given image is divided into NxN subblocks and transformation is applied to each block .Then, a threshold value is selected such that to minimize the mean square value between Original ima...

In this study, novel CuO/g-C3N4 nanocomposite was simply synthesized by impregnation of g-C3N4 with CuO nanoparticles. Then, the heterogeneous catalyst was characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and transmission electron microscopy (...

In the present study, Fe3O4 super paramagnetic nanoparticles were synthesized via co-precipitation of Fe3+ and Fe2+ chloride salts in the presence of ammonia Solution. The product was characterized by Fourier Transform Infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and zeta–potential particle size distributing methods. The synt...

In this research, Keggin-type polyoxometalate, H5PMoV2O40 (denoted as PMoV) was immobilized on modified NiFe2O4 nanoparticles to produce a magnetically separable catalyst. This catalyst was characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), cycli...

Abstract Direct current tests performed in the past on conductor samples of toroidal field (TF) ITER coils revealed degradation sharing temperature, T cs . The progresses with repetitive electromagnetic loading, and also thermal cycles between 4.5 K room temperature. This feature was observed short SULTAN test facility (EPFL-SPC, Switzerland) as well TF Insert Coil CSMC (Naka, Japan). We presen...
