Dear Ezekwen

Al nanoparticules are aggregated: individual ones are bonded and generate colloidal network

Ti ones look like anatase are more or less dispersed but little bit collapse and it is difficult to determine the size of single ones

My comments:

1. It will be better to work at lower magnification using high contrasted mode (Contrasted Bright Field with a small objective diaphragm) to be sure to observe a large set of particules

In a past study on SiC crystal size in Nicalon fiber  we try to answer to the following question : how many crystals should we have to count to get an estimation of the size. A minimum of 120 have to be consider

2. The sample preparation is key parameter and then the nanoparticules should be dispersed : how do you proceed?

    Do you use some dispersant molecules (CaCl for example or a drop of organic dispersant like washing liquid) ?

3. On your Al micrography: up left there is some ligand molecules : are you sure of the purity of your sample?

4. After checking these points you can used free image software like ImageJ to determine independantly different parameters such size, form, etc.

I am sorry to be not able to provide you a short and simple easy solution to get the right information

Keep in touch
