Pollutant particles with a smaller diameter, density, and flow rate can enter the deep lung, but large particles with a low density may also enter the deep airways, according to a study. Researchers ...

In this study, we numerically investigated the orbital evolution of cometary dust particles, with special consideration of the initial size frequency distribution (SFD) and different evolutionary ...

Current evidence suggests that microparticles of cosmic dust collide and stick together to form larger dust aggregates that may eventually combine and develop into planets. Numerical models that ...

Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a ...

Large amounts of dust are released from traffic emissions, industrial operations, and waste disposal activities, directly or indirectly pollute the environment, especially the soil and the atmosphere.

Several factors influence the lower limit of effective particle size detection using the dynamic light scattering (DLS) method. These factors include the optical path design, detector type, laser ...

Air filtration, as we all know, is the process of separating dispersed particles from air by means of porous media. Filter fibers are expected to separate and retain particles on or within the filter ...
