Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...

The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...

Calcium phosphate (hydroxyapatite and tri-calcium phosphate) bioceramics closely resembling, in chemical composition, those found in vivo in human bones have been synthesized by using novel synthetic body ̄uid solutions via the self-propagating combustion synthesis (SPCS) method. Powder characterization was performed by XRD, ICP-AES, FTIR and SEM. # 2000 Elsevier Science Ltd. All rights reserved.

Ways to reduce nitrogen oxide emissions One of MTU ś aims for its engines is to reduce the emission of soot particles and nitrogen oxides in order to achieve compliance with increasingly strict emissions regulations around the world. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into account a basic principle ...

Calcium phosphate (single-phase HA, single-phase TCP, and biphasic HA-TCP) nanowhiskers were synthesized using a novel microwave-assisted “combustion synthesis (auto ignition) /molten salt synthesis” hybrid route. This work is an example of our “Synergistic Processing” philosophy combining the aforementioned three technologies while utilizing their useful aspects. An important part of this work...

Ni-based catalysts with different amounts of Na as promoter from 2 to 6 wt % were prepared by solution combustion method. The catalytic activity was investigated in syngas methanation reaction. Carbon oxides conversion and methane selectivity are greatly influenced by sodium loading. Adding 2 wt% Na remarkably improves catalytic activity and long-term stability, attributed to its smaller mean N...
