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 ...

The blue-emitting phosphor cerium activated yttrium silicate, (Y1 mCem)2SiO5, was prepared via a novel synthesis technique called combustion synthesis. Combustion synthesis involves a highly exothermic redox reaction between metal nitrates and an organic fuel to produce a solid powder. The combustion synthesis parameter, the fuel-to-oxidizer ratio, has a direct effect on the physical properties...

Nickel titanium (NiTi) foams were made by combustion synthesis of powders with the help of ZrH2 as foaming agent and TiB2 as endothermic agent. In this paper, we investigated the effect of elemental powder size on the foaming. The powder size of Ni and Ti affected the ignition temperature of the combustion reaction, cell morphology and microstructure of the foams. The cell morphology of the foa...

The thermodynamics of amide and peptide bonds is of fundamental importance in the study of the synthesis and breakdown of proteins in biological systems. One of the necessary steps in acquiring significant thermodynamic data in this field is the determination of the changes in heat content accompanying the formation or rupture of such bonds in compounds of known structure. We have accordingly u...

AS MORPHOLOGY PLAYS A RELEVANT ROLE IN SOLID/SOLID CATALYSIS, WHERE THE NUMBER OF CONTACT POINTS IS A CRITICAL FEATURE IN THIS KIND OF REACTION, THREE DIFFERENT CERIA MORPHOLOGIES HAVE BEEN INVESTIGATED IN THIS WORK AS SOOT OXIDATION CATALYSTS: ceria nanofibers, which can become organized as a catalytic network inside diesel particulate filter channels and thus trap soot particles at several co...

In this work, the different fuels (citric acid, glycine and urea) were used for solution combustion synthesis of CoFe2O4 powders. X-ray diffraction, Raman spectroscopy, electron microscopy and vibrating sample magnetometry techniques were employed for characterization of phase evolution, cation distribution, microstructure and magnetic properties of the as-combusted CoFe2O4 powders. Single phas...

The Cluster of Excellence (CoE) ̈Tailor-Made Fuels from Biomass ̈ (TMFB) takes an interdisciplinary research approach towards new synthetic fuels based on biomass feedstock. New target-designed synthesis pathways, employing novel catalytic systems, reaction solvents and tightly integrated production processes, which embed intensified process units for fuel production, are considered to create new...

This current study reports preparation of Nickel-Gadolinium doped Ceria (Ni-GDC) composite via controlled unidirectional freeze casting of aqueous-based GDC slurry completed with nickel infiltrated into the porous GDC samples. Gadolinium doped ceria powder prepared by gel-combustion synthesis method. The oxide powder was confirmed to be the fluorite-structured of Ce0.8Gd0.2O1.9 solid solution b...
