Ammonium glycolate combustion was used to synthesize SrZr0.95Y0.05O3−x powders. Soluble metal-glycolate complexes, detected by infrared spectroscopy, were formed with Y+3 and Zr+4, which maintain atomic level mixing of metal cations with glycolic acid. Sr+2/glycolic acid mixtures did not form glycolate complexes. Temperature-programmed reaction studies showed that only precursor solutions with ...

Nano-sized particles of ceria with high surface area were processed by solution combustion synthesis (SCS) and their catalytic activity towards combustion of carbonaceous materials was compared with that obtained by simple thermal decomposition of cerium nitrate, exhibiting the same specific surface area. These two kinds of ceria powders were tested, by DTA and temperature programmed combustion...

The dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. Cu and Ni Unites nanocatalyst powders sithcomposition of Caned], and NiFe204 were synthesized by a sol-gel auto catalnic combustion process. Themolar ratio between metal ions and urea was 11.2. The sob gel process was done at 8...

AgAl2O3 nanocomposite were synthesized by solution combustion Technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. Samples prepared with different amount of silver, were characterized by XRD, BET, SEM and optical Absorption measurements. XRD analysis was used to determine the change in phase and size of the synthesized n...

Nanomaterials with characteristic structural dimensions on the order of few nanometers (1–100 nm) attract wide attention owing to their unique properties. They found a variety of applications in different branches of science and industry including catalysis, micro and biotechnologies, energy storage and conversion devices, such as fuel cells. Different techniques have been developed for nanomat...

Ethnomethodology is an established method of research in technology related fields. In work settings, ethnomethodology has helped researchers to deepen their understanding of how collaborative activities unfold in a social context. While much collaboration is now carried out online, through distributed teams for example, ethnomethodology, as a method of analysis, has not received considerable i...

Fatty acid-derived biofuels can be a better solution than bioethanol to replace petroleum fuel, since they have similar energy content and combustion properties as current transportation fuels. The environmentally friendly microbial fermentation process has been used to synthesize advanced biofuels from renewable feedstock. Due to their robustness as well as the high tolerance to fermentation i...

While the synthesis of TiO2 hollow structures is well-established, in most cases it is particularly difficult to control the crystallization of TiO2 in solution or by calcination. As a result, TiO2 hollow structures do not really exhibit enhanced lithium storage properties. Herein, we report a simple and cost-effective template-assisted method to synthesize anatase TiO2 hollow spheres composed ...

Successful implementation of molecular solution processing from a homogeneous and stable precursor would provide an alternative, robust approach to process multinary compounds compared with physical vapor deposition. Targeting deposition of chemically clear, high quality crystalline films requires specific molecular structure design and solvent selection. Hydrazine (N2H4) serves as a unique and...
