Particle Size Distribution of Copper Nanosized Powders Prepared by Pulsed Wire Discharge

Particle Size Distribution in Food Powders

Stability of a-Si:H prepared by hot-wire and glow discharge using H dilution evaluated by pulsed laser degradation

The quality of intrinsic amorphous silicon films prepared by different deposition techniques was investigated. For very high frequency glow discharge, both the substrate temperature as well as the hydrogen dilution were varied. These layers were compared to hot wire material produced at comparable temperatures. To study the stability of these films, an optimised degradation method was developed...

Successful Particle Size Analysis of Dry Powders

A correctly set up dry powder measurement using a laser diffraction particle size analyser is much easier to perform than measurement of wet suspensions. However, incorrect measurement set-up can lead to errors and inconsistencies. This article examines the key steps achieving successful dry to powder measurement. Issues examined include powder flowability and sampling, air pressure and sample ...

Particle size distribution by LASER diffraction spectrometry: application to cementitious powders

Particle size distribution (PSD) measurements are now routinely employed to characterize cement powders. A variety of techniques are available for this purpose. However, at present, an industry standard does not exist for PSD analysis, nor do uniform methods exist for sample preparation. Two international round-robin tests sponsored by ASTM committee C01.25.01 revealed high variability in repor...

CTAB-assisted of Fe2O3/CeO2 nanosized prepared by coprecipitation method

Recently, cerium oxide (CeO2) nanoparticles have been widely used in engineering andmedical sciences due to the diversity of their applications. Fe-Ce nanoparticles were synthesized bysimple co-precipitation method via iron nitrate (Fe(NO3)3.9H2O) and cerium nitrate (Ce(NO3)3.6H2O) asprecursor in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The samples wer...
