Background - Particle size is not well defined
Background - Particle size is not well defined Fine and nanoparticles can be defined in many ways. Especially when defining the particle size and concentration. Particle size can be measured either off-line or on-line. Off line techniques typically give out particle filter mass concentration. Off-line techniques are seldom used to define particle size. When this is done, electron microscopy is ...

Blending of Log Normal Particle Size Data from Multiple Analyses into Continuous Data Set
Abstract Image analysis is one method by which particle size may be measured. In many cases, it is considered the "gold standard" of particle size measurement and is often used to verify the results of other techniques. Sample particle size distributions are often broad, sometimes covering two to three decades of particle diameter. It is also common to analyze samples that are multi-modal (e.g., ...

Supercooled Liquid Water is Hazardous to Your Health!
What is Supercooled Liquid Water? Supercooled Liquid Water (SLW) refers to water droplets in a cloud that can stay in a liquid state at below freezing temperatures. If an airplane flies into these SLW droplets, icing on the wings and airframe can occur. SLW droplets larger than 30 microns create the biggest hazard for aircraft because they don’t freeze immediately, allowing them to ...

Potential for metal contamination by direct sonication of nanoparticle suspensions
While conducting toxicity tests with nano titanium dioxide, the authors found that test suspensions were being contaminated with aluminum and titanium from tip erosion during direct sonication. The contaminating alloy particles had a measurable size distribution and zeta potential using dynamic light scattering, which changed the measured characteristics of the suspensions. Caution should be ...
