Teacher pathways through the particulate nature of matter in lower secondary school chemistry: Continuous switching between different models or a coherent conceptual structure? In G. Tsaparlis & H. Sevian (Eds.), Concepts of matter in science education, (pp. 213-230). New York, NY: Springer....
Inorganic Chemistry of Particulate Matter from the Nearshore Zone of Lake MichiganParticulate matter from a nearshore region of southeastern Lake Michigan serves as a sink for trace metals and a conveyor of trace metals to the sediments. Fe, K, Mg, and Mn are always more concentrated in the ...
In subject area: Chemistry Fine Particulate Matter refers to small particles that escape from bulk powders and become airborne outside of the equipment used for conveying, storing, hauling, or processing. These particles can be captured by ducts, stacks, or dust collection equipment. ...

We obtained dust-mineralogy, chemistry, and particle size attached to pollen by X-ray diffraction and scanning electron microscope. Results show that seasonal high PM-loading in the urban atmosphere coincides with aeroallergens promoting micro- to nanoparticles’ attachment to pollen’s surface. A ...
