temperature

Atmospheric oxygen is used for the reaction

Results

X-Ray diffractogram

Fe3+ (0.68A) and Ti4+ (0.64A) ions have similar ionic radius. Slight deformation of structure was detected. Iron is well dispersed (and the very small amount?) on the surface of titania particle. Iron cannot be detected by XRD.

Results TiO2 nanotubes fabrication

All images are the architecture resulting from Ti anodization in an ethylene glycol bath. Foils were anodized in 0.5 wt% HF aqueous solution at anodizing voltages of: 3, 5, 10 and 20 V. At low anodization voltages, the film morphology is similar to that of porous (sponge-like) alumina , with a typical pore sizes from 15 to 30 nm.

What causes humidifier fever?

Bacterial and fungal organisms can be

emitted from impeller and ultrasonic

humidifiers

Mesophylic fungi

Thermophylic bacteria

Thermophylic actinomycetes

Airborne concentrations of microorganisms are

noted during operatiojn and might be quite high for

individuals using ultrasonic or cool mist units

The EPA estimates the incidence rate within a

workplace may exceed 25% ("Indoor Air“)

New Topics !! 2014 :

Tissue with water has toxic chemical

protecting bacteria etc.
