Iron-oxide nanoparticle synthesis from liquid spray flames under variable pressure conditions
Iron-oxide nanoparticles have been synthesized via liquid-fed flame spray pyrolysis (FSP) under variable pressure conditions. The work focuses on the effect of pressure, precursor flow rate, and flame stoichiometry on particle size, composition, and morphology. [...]
Effect of particle presence on gas phase temperature in the flame spray pyrolysis
Engel S.R., Gao Yi, Koegler A.F., Kilian D., Seeger T., Peukert W., Leipertz A., Department of Engineering Thermodynamics, DE
For the production of manufactured nanoparticles at a commercial scale flame processes are most frequently used. An important basis for understanding the complexity of this process is the characterization of the combustion process in dependence [...]
Synthesis of Copper Nanoparticles by a High Power Pulse Hollow Cathode
A novel plasma-based nanoparticle synthesis method using high power pulses has been developed. A high power pulse similar to high power impulse magnetron sputtering is applied to a cylindrical hollow cathode leading to a high [...]
A Novel Pulsed High-density Plasma Process for Nanoparticle Synthesis
Today there are various plasma techniques where material is sputtered and used to synthesize nanoparticles. However, we have been unable to identify anyone ionizing the sputtered material in such a process. The advantage of ionizing [...]
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 [...]
Continuous synthesis of highly-specific silicon nanopowder on the pilot-plant scale
Hülser T., Schnurre S.M., Schulz C., Wiggers H., Institute of Energy and Environmental Technology (IUTA), DE
In this work we present the formation process of crystalline and amorphous nanostructured silicon made from a continuously operating hot-wall reactor synthesis process. In this reactor, silicon particles are synthesized at variable operating conditions varying [...]
Synthesis, Characterization and Toxic Metal-Binding Ability of Poly(γ-glutamic acid)-coated Superparamagnetic Nanoparticles
Superparamagnetic iron oxide nanoparticles (SPIONPs) coated with a non-toxic, edible biopolymer poly(-glutamic acid) (PGA-coated SPIONs) were synthesized by co-precipitation method, characterized and evaluated for their possible toxic metal-binding ability in the treatment of metal intoxication [...]
Stability of Functionalized Magnetic Particles in a Physiologic Fluid
Baca Ramos K., Martínez Pérez C.A., Camacho Montes H., Olivas Armendáriz I., Martel A., García-Casillas P.E., Universidad Autonoma de Ciudad Juarez, MX
Magnetic materials are widely used in biomedical applications such as magnetic separation, magnetic resonance imaging, drug delivery and hyperthermia. In these applications the nanoparticles are functionalized in a core/shell type with polymeric materials which contains [...]
