Increasing pH and IS enhanced aggregation, while increasing NOM decreased mean aggregate sizes.
Low-magnification TEM images captured aggregation size properties of Sample 2. Figure 1(b) shows a representative image, with the aggregation mean-size of 150 nm corroborating the DLS measurement results.
The change in aggregation size was detected for another 72 hrs.
For example, searching for "aggregation" leads to all different phenotypic defects related to aggregation: aberrant aggregation, delayed aggregation, precocious aggregation, abolished chemotaxis to cAMP during aggregation, aberrant regulation of aggregate size, etc. Figure 5B shows a number of mutant strains annotated to "abolished aggregation".
The TEM analysis clearly shows that with increasing Au S molar ratio also the particle aggregation and the mean particle size increases (diameter ≈ 9 nm) as measured on isolated nanoclusters in Figure 4c. Figure 6 Bright field TEM images of benzylthiol-gold nanoparticles prepared with Au/S molar ratio 15:1 (A4) taken with different magnification.
With this reactor, induction kinetics are reproducible and agree with a model describing the mean particle size increase by a slow aggregation process.
Particle size of the system upon storage was also monitored to assess system stability in terms of drastic changes in the mean particle size due to coalescence or aggregation.
This sample also contained irregularly shaped aggregations, with the mean size of individual microparticles in the range from 3.8 to 5.7 μm (Additional file 1: Figure S2c).
The dynamics of aggregation is characterised in terms of SCP mean size, size distribution, fractal dimension, distribution of orientations and radial distribution function.
The remaining inorganic network exhibits an additional interconnected microporosity with a mean pore size of 1.5 nm, resulting from the aggregation of the anatase nanoparticles.
In our conclusion, we suggest the use of effective mesh size (MESH), mean patch size (AREA_MN), landscape patch index (LPI), COHESION, and aggregation index (AI).
