Powders and granules of heavy metal oxides produced through condition monitoring are in high demand as intermediate products for obtaining fine-grained ceramics a wide range applications, i.e., nuclear fuel elements power plants. Sol–gel technology to produce (UO2), well catalysts (ThO2) organic synthesis the form from pressed microspheres, is promising method obtain powders (fine-graded cerami...

This study introduces a novel titanium dioxide carbon nanofiber (TiO2-CNF) support for anodic catalyst in direct methanol fuel cell. The catalytic synthesis process involves several methods, namely the sol-gel, electrospinning, and deposition methods. The synthesized electrocatalyst is compared with other three electrocatalysts with different types of support. All of these electrocatalysts diff...

Silicates are well known for their bioactivity, here we are reporting the bioactivity of diopside (CaMgSi2O6) synthesized by sol-gel combustion process by using citric acid and succinic acid as a mixed fuel. The phase formation of the prepared sample was confirmed by powder X-Ray Diffraction. In-vitro bioactivity of the diopside in conjugation with biopolymer chitin in various proportions were ...

A novel anode material for intermediate temperature solid oxide fuel cells with a composite of LaxSr1-xTiO3 has been synthesized by a sol-gel auto-combustion method. X-ray diffraction (XRD) shows that LaxSr1-xTiO3 has good chemical compatibility with Gd0.2Ce0.8O1.9 electrolyte. The thermal expansion coefficient (TEC) of the as-prepared anode material is similar to that of Gd0.2Ce0.8O1.9. The el...

Here, we report a remarkable 15 Å nanolayered tin phosphate, Sn(HPO4)2·3H2O (SnP-H+ or SnP), and its clay-like gel, which are multifunctional and are prepared using earth-abundant Sn and P chemicals by a facile, environmentally benign and potentially cost-effective process. This new energy material is discovered here as the best proton conductor among all the known layered phosphates with a ver...

La0.8Sr0.2CoO3 was coated on NiO (LSC–NiO) cathodes using a sol–gel method. Dissolution studies in molten Li2CO3 and K2CO3 (62:38 mol%) at 650 8C showed lower Ni dissolution than that of the conventional nickel oxide cathode. Impedance analysis showed that the behavior of the developed cathode is similar to that of nickel oxide. The LSC coated Ni cathode has an over potential of 109 mVat an app...

To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...
