These particles were produced (4-15 g/h) by oxidation of hexamethyldisiloxane (HMDSO) in a coflow diffusion flame reactor. Their average primary particle size (10-50 nm) and degree of agglomeration were controlled by varying the oxygen and precursor flow rates. The particles were characterized by nitrogen adsorption, electron microscopy, and small-angle X-ray scattering. Hydrodynamic stresses break up soft agglomerates and yield hard agglomerate sizes in the range of 100-180 nm, as characterized by dynamic light scattering. Soft agglomerates exhibited decreasing light scattering diameters with increasing dispersion pressure, while hard agglomerates were insensitive.", "doi": "10.1021/la053283n", "pmid": "16700577", "labels": {"Alexandra Teleki": null, "SciLifeLab Fellow": null}, "xrefs": [], "notes": [], "created": "2020-11-30T21:42:49.388Z", "modified": "2022-11-07T11:29:43.766Z"}
