Rapid Combustion Synthesis of Zinc Oxide Nanostructures

Merchan-Merchan W., Farmahini Farahani M., University of Oklahoma, US

In this contribution we show that Zn oxide nanostructures of various morphologies can be formed at high rates by using a counter-flow flame. A 1.0-mm in diameter Zn probes with a purity of ~99.99% is [...]

Flame Deposition of Superhydrophobic and Superhydrophilic Nanoparticle Coatings on Paperboard Materials

Aromaa M., Haapanen J., Teisala H., Tuominen M., Stepien M., Saarinen J.J., Toivakka M., Kuusipalo J., Mäkelä J.M., Tampere University of Technology, FI

Liquid Flame Spray is one of the flame aerosol methods for the nanoparticle synthesis. Here, it is used in depositing the particles directly on a moving roll-to-roll substrate. The deposition process is performed in a [...]

Flame Synthesis and Coating of Nanostructured Particles in One Step

Teleki A., Buesser B., Heine M., Krumeich F., Akhtar M.K., Pratsinis S.E., ETH Zürich, CH

Coating of flame-made nanostructured particles has been achieved in one step by a scalable aerosol process. Rutile TiO2 particles made by flame spray pyrolysis (FSP) were coated in a single step with SiO2 layers in [...]

Synthesis of Y2O3:Eu Phosphor Nanoparticles by Flame Spray Pyrolysis

Qin X., Ju Y., Bernhard S., Yao N., Princeton University, US

Nanoscale Y2O3:Eu phosphor particles were synthesized by flame spray pyrolysis method and the effects of precursor solution and annealing treatment were discussed. The flame spray pyrolysis system consists of a spray generator, a coflow burner, [...]
