Abstract:

One of the methods for the reduction of harmful emissions from diesel engines such as hydrocarbon, soot and NOx is the use of fuel born catalyst Cerium oxide. The oxygen storage capacity of Cerium oxide can be improved by coating it with metal such as Zirconium. Zr – Ce-O nanoparticles were synthesized by Co-precipitation method in the present work. Dynamic Light scattering, XRD pattern and UV-Visible spectroscopy were used for characterization of the prepared samples. Thermo gravimetric studies were conducted to investigate the thermal decomposition of Zr-Ce-O nanoparticles. The oxygen storag

Abstract:

This study investigates the magnetic and dielectric properties of cobalt–zirconium co-doped iron oxide nanoparticles synthesized via the hydrothermal method. The synthesis was conducted at 150 °C, with reaction times of 4, 6, 8, 10, and 12 h. Co-doping with cobalt and zirconium significantly influenced the magnetic phase formation of iron oxide. Magnetic properties were characterized using a Vibrating Sample Magnetometer (VSM), revealing ferromagnetic behavior with a maximum saturation magnetization of 45 emu/g for the 8 h sample. The dielectric properties were analyzed through impedance spect

Abstract:

One of the methods for simultaneous improvement of combustion efficiency and reduction of hydrocarbon and nitrogen oxide emissions from diesel engines is the use of catalyst in nanosized form in diesel. Agglomeration of nanoparticles in the base fluid being a serious issue, stability of the nanofluid i.e. the catalytic nanoparticles in diesel is of much concern. In the present work Zr-CeO2 nanoparticles, which acts as storage buffer leading to the reduction of the emissions, were suspended in diesel. The nanofluids were synthesized by two step method and the dosing levels of Zr-CeO2 were varie

Abstract:

The aim of the current work is the synthesis and characterization of metallic Zr nanoparticles. The preparation is carried out by using the RAPET method (Reaction under Autogenic Pressure at Elevated Temperatures) developed in our lab. The RAPET reaction of commercial ZrO2 with Mg powder was carried out in a closed stainless steel cell, at 750 °C. On completion of the reaction, the additionally formed MgO is removed by treatment with acid. The characterization of the product was performed by XRD, X-ray absorption spectroscopy, SEM, TEM and elemental analysis. The XRD pattern reveals that the p

Abstract:

The demand for fuel is increasing everyday life and its risks poses a serious problem to this globalization. It is an unprecedented alternative fuel source for biodiesel designed to increase the value of fossil fuels and increase the longevity and purity of the diesel engine. The origin of fossil fuels will decrease in the coming years, besides, the price and demand for fuel will be rare. The negative environmental barrier prompted researchers to find alternative fuels for fossil fuels. Biodiesel from watermelon seed oil (WSO) had a lot of appeal and could be a different alternative to diesel

Abstract:

This paper describes thermodynamic modeling of the NiAl–CrMoCo system with the calculation of the equilibrium composition and thermodynamic parameters of the system. NiAl-Cr-Mo-Co alloy samples of equiatomic composition, including those with a small addition of zirconium oxide nanoparticles, were obtained by spark plasma sintering of mechanically alloyed powders. It was found that the material had a two-phase structure with wedge-shaped regions enriched in cobalt and molybdenum with a gradient distribution. In addition, in the regions enriched with (Cr, Mo) phase, a lamellar σ phase was found.
