OK, I have some points and questions to add:

• Nowhere in the poster is a real TEM or SEM picture but simply pictures or cartoons. Is the stick and ball picture in the middle column a real representation of what we’d see under the electron microscope? Why are there no real examples?

• Shape is a 3- issue. How is the third (z) dimension dealt with especially as many shape parameters (e.g. aspect ratio) are ratios of 2D dimensions?

• How does sample preparation affect the generated result? For example, microtoming in TEM? See the attached picture, from A Primer of Higher Space Claude Bragdon, referring to slicing a cube

• How are primary particles, aggregates (tight, chemically bound), agglomerates (loose, physical), and touching (no interaction) particles dealt with? In software? If the latter, how is software ‘dispersion’ accomplished?

• Why are the graphics in the third column not complying with the ISO recommendations (ISO 9276-1:1998 Representation Of Results Of Particle Size Analysis -- Part 1: Graphical Representation) for displaying particle size distribution graphics? That is, logarithmic horizontal (x) axis and linear (y; Q, quantity) axis? How can one have particles of 0 units in measurement?

• Why in imaging is a 1 unit particle as important as a 1000 unit particle when the 1000 unit particle contains 1 billion times the mass/volume and hence material value (if Au, for example)?

Also take a look at:

Sem/tem images are not specific, they are functions of different properties of materials.

The representations on poster are Nano structures, at least portraying the ability of the software to accurately calculate particles down to nanoscale..

In our definition..3 dimensional simply means volume .

Your sample preparation has nothing to do with the software rather, it is what will be reflected on the images generated by SEM/TEM.

However, the images are further processed prior to analysing them.

The graphics in the third column are only depicting the applications of nanomaterials..

Thanks

Dear Olabimtan H Olabode , it looks like you do not have a grasp on image analysis problem. Software has nothing to do with particle size. It makes no difference for image analysis software whether particles are of nano or kilometer size. It's all the same. Sorry, but your attempt of advertising of some questionable package failed.
