Sampling is one of the most important aspects of particle size analysis. If a biased sample is analyzed, a biased particle size distribution will be recorded. The requirement for good sampling not ...

Specimen mounting in x-ray powder diffraction affects peak positions and intensities. The specimen-mount procedure is one of the many actions an investigator employs that could dramatically affect ...

Fine powders and granular materials are extensively employed in industrial applications. These materials have to be properly characterized to control and to improve the processing techniques. The ...

Internal corrosion generates black powder inside pipelines, while the composition of transported gas determines the powder’s composition. Preventing its occurrence or effectively managing the effects ...

This article considers the different conditions to which the powder is subjected in the tableting process, and discusses which powder properties should be measured to accurately reflect likely powder ...

NASA's Curiosity Mars rover used its robotic arm Wednesday, March 11, to sieve and deliver a rock-powder sample to an onboard instrument. The sample was collected last month before the team ...
