Optical Diagnostics of Iron Oxide Nanoparticle Synthesis in Microwave Oxygen Plasma

T1-MRI Fluorescent Iron Oxide Nanoparticles by Microwave Assisted Synthesis

Iron oxide nanoparticles have long been studied as a T₂ contrast agent in MRI due to their superparamagnetic behavior. T₁-based positive contrast, being much more favorable for clinical application due to brighter and more accurate signaling is, however, still limited to gadolinium- or manganese-based imaging tools. Though being the only available commercial positive-contrast agents, they lack ...

Microwave-assisted synthesis of molybdenum oxide nanoparticles

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

Optical Techniques in Plasma Diagnostics

Recent developments in optical techniques for plasma diagnostics are critically reviewed. The primary emphasis is on plasma-induced emission and laser-induced fluorescence probes of radical and ionic concentrations and temperatures in low pressure discharges like those used in microelectronic fabrication. Other techniques such as optogalvanic, infrared, spontaneous and stimulated Raman, and mul...

Thermal Plasma Synthesis of Superparamagnetic Iron Oxide Nanoparticles

Superparamagnetic iron oxide nanoparticles were synthesized by injecting ferrocene vapor and oxygen into an argon/helium DC thermal plasma. Size distributions of particles in the reactor exhaust were measured online using an aerosol extraction probe interfaced to a scanning mobility particle sizer, and particles were collected on transmission electron microscopy (TEM) grids and glass fiber filt...
