Characteristics of airborne gold aggregates generated by various methods: mass mobility characteristics and surface area

Creator/Principal investigator(s):

Christian Svensson - Faculty of Engineering, Lund University, Department of Design Sciences

Description:

Aggregates are a common particle type in the air - irregular particles built up by smaller primaries/monomers. One aim of the work is to present and test methods, experimental and theoretical, to characterize aggregates in the transition regime with regards to properties relevant for toxicological and nano-technological applications. Furthermore, we characterize and compare the properties of the gold-aggregates generated by three generators. The generators tested were a high temperature evaporation furnace (HT) and two spark discharge generators, one commercially available (SDGP) and a custom built (SDGC). The SDGC has been applied in several studies relevant for toxicology.

For the characterization both online instrumentation, such as differential mobility analyzer and aerosol particle mass analyzer coupled in series (DMA-APM) and differential mobility particle sizer (DMPS), and off-line transmission electron microscopy techniques were used. Except from size, number, mass, and morphology, the surface area is a property of special interest. Based on the experimental data, the total surface ar

Description:

The .zip-file contains data in an excel file. The data is divided between two tabs, where the first one lists size of primary particles over several hundred observations and the second one presents the results of the testing of the different generators. For the latter, size of particle works as the independent variable whereas dependent variables are weight, shape factor as well as effective density. The .zip-file also includes a codebook with variable descriptions in English.
