Ferrite nano particles of basic composition Ni Cd Smx Fe2-xO4(0.0 ≤ x 0.05, X=0.01) where synthesized by citrate-gel auto combustion method have investigated. X-ray diffraction profile indicates that the samples are in single phase structure for sample without Sm content. For with ions, some peaks appeared which belongs to orthorhombic further, XRD been used calculated lattice parameter, densit...

Low-cost and efficient electrode materials play a key role in improving the performance of lithium-ion battery. In this paper, single-crystalline LiMn2O4 nanoparticles were synthesized through gel combustion method assisted by microwave followed calcination treatment. High-quality single-crystallinity characteristics precursor powder could be well retained after high-temperature (990 °C) solid-...

hot spots are among the most serious operational issues in furnaces as they may result in the destruction of tubes. hence, it is essential to locate such hot spots precisely on the tube surfaces inside the industrial furnaces in order to secure a safe design and operation. in the current study, we have extended the model proposed by talmor in order to precisely locate the combustion hot spots o...

Future internal combustion engine technologies require an accurate combustion monitoring and control. This can be performed through high frequency recordings of cylinder pressure. However, this solution is limited by the sensor cost and reliability. Another method consist in reconstructing combustion related variables from indirect measurements. In this paper, we propose a combustion indicator ...

In this study, Zinc oxide nanoparticles were synthesized by gel-combustion method using a novel bio-fuel tapioca starch pearls, derived from the tubers of Mannihot esculenta, to investigate the photocatalytic degradation of ccaffeine. The ZnO photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible spectroscopy. X-ray diffractometry result f...

ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...
