Fluidization of fine particles
Chemical Engineering Science, 1998Experiments on the fluidization of fine particles (Geldart group C) with mean sizes 0.01-18.1 mu m and densities 100-8600 kg/m(3) were conducted. Experimental results show that the process of fluidizing fine particles usually involves plugging, channeling, disrupting, and agglomerating.

Glassy Particles in Lunar Fines
Nature, 1970Most of the Apollo 11 glassy particles differ from those generated by terrestrial volcanism, by meteoritic impacts, or by the condensation of the parent bodies of meteorites. Some of the particles may have been formed by the action of solar flares on the lunar surface.

Personal Exposure to Fine Particles in Children Correlates Closely with Ambient Fine Particles
Archives of Environmental Health: An International Journal, 1999To investigate the validity of ambient fine-particle concentrations as a measure of exposure in epidemiological time-series studies, we established the association between personal and ambient concentrations, within subjects, over time. We conducted repeated measurements of personal and ambient fine-particle concentrations in 13 children who lived in ...

Apparent particle density of a fine particle
Powder Technology, 1988Abstract The electrodynamic balance is used to measure the apparent density of individual synthetic char particles known as ‘Spherocarbs’. A distribution in apparent density measurements seems to correlate with the existence of large cavities inside some of the ‘Spherocarb’ particles.

Behavior of fine particles in a spouted bed consisting of fine and coarse particles
The Canadian Journal of Chemical Engineering, 1983AbstractThe elutriation of fines from a spouted bed of fine and coarse particles has been studied. Equations for correlating elutriation rate coefficients are proposed. Three different regions associated with particle behavior have been identified in a way to permit calculation of elutriation rate at any column height. Measurements of cross‐sectionally

The Remanent State Of Fine Particles
[1993] Digests of International Magnetics Conference, 1993Computations of the structure and energy of the magnetization configurations in very small particles have reached the limit of validity of the basic assumptions used in this theory, and the analytic models which have been published so far are not more reliable, for anything but ellipsoids. A review of all the theoretical studies leads to the conclusion

Classification of Fine Particles
Particulate Science and Technology, 1997ABSTRACT Experimental results with two new classifiers for in-line and off-line operation are presented. The first type is a cyclone classifier, in which the vortex finder is exchanged with an impeller wheel enabling cut sizes between 5 and 100 µm.

Environmental Science & Technology
The negative effects of air pollution, especially fine particulate matter (PM2.5, particles with an aerodynamic diameter of ≤2.5 μm), on human health, climate, and ecosystems are causing significant concern. Nevertheless, little is known about the contributions of emerging pollutants such as plastic particles to PM2.5 due to the lack of continuous ...
