The current work presents the results of an experimental investigation of gas-phase combustion synthesis of silica (SiO2) particles using a multi-element diffusion flame burner (MEDB, a Hencken burner). Silane (SiH4) was added to hydrogen/oxygen/argon (H2/O2/Ar) flames to produce SiO2 nanoparticles at various burner operating conditions ( 0.47–2.16). To characterize the burner performance, temp...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

In recent years progress in the materials research field has been associated with the discovery of graphene and other twodimensional atomic crystals. Those materials uniquely combine many exceptional properties, which make them highly attractive for a variety of applications. Despite significant advancement in synthesis and processing, the relevance of those materials is essentially driven by p...

The kinetic parameters of ethylene combustion in the presence of acetic acid, i.e., during the synthesis of vinyl acetate and in the absence of acetic acid, have been measured in the temperature range 413–453 K over Pd supported on a high surface area SiO2 (600 m 2/g) at pressures ranging from 5.0 to 15.0 kPa of C2H4 and 1.0 to 10.0 kPa of O2. CO2 formation as a function of the partial pressure...

A parallel solution combustion synthesis technique was developed for combinatorial materials studies. The vigorous combustion reactions were successfully limited in the microreactors by using a substrate-net-mask microreactor system and the lowest adoptable furnace temperature. Using this technique, a luminescent materials library of Y3Al5O12/Tb(chi) was synthesized with the aid of an ink-jet d...

In the current work, a novel combustion method is demonstrated for the direct synthesis of nanocomposite materials. Specifically doped tin dioxide (SnO2) powders were selected for the demonstration studies due to the key role SnO2 plays in semiconductor gas sensors and the strong sensitivity of doped SnO2 to nanocomposite properties. The synthesis approach combines solid and gas-phase precursor...

This review considers a specific domain in combustion science, so-called discrete combustion waves, which have been observed in a variety of processes including combustion synthesis of materials, burning of solid propellants, coals and biomass. The main objective of this work is to discuss the relevant experimental and theoretical results and to bring to light the fundamental nature of this phe...
