SEM Micrographs Interpretation in Experimental paper: Scanning Electron Microscopy SEM Analysis

How to interpret SEM/FESEM micrographs in your research paper or thesis?
SEM is versatile and a powerful tool for material characterization.
SEM becomes more useful and necessities Due to the continuous shrinking of the material’s dimension for copious applications.

If you are particles are well disperse then no agglomeration. But if look the other way round then it is and you need to change the strategy in solution.

How to prepare sample (insect) for heavy metal using SEM?

[@qamarwali]

Sorry for the late response. I don't know about the insect sample presentation. But, SEM will provide the surface morphology of the sample. For sure, the shape, size, and surface morphology will be revealed by SEM .

[@appanamuralidhar6898]

Sir what are the parameters meant for like 1micro meter and *12000 and 0.5kv what all these means please tell me sir

[@qamarwali]

The micro meter or nm is basically the scale and kV is operating voltage. If we go for higher magnifcation, the scale must go from micro to nm

[@madhumathiravichandran8586]

Sir can you please tell me the magnification of 5um=50times or 500times

[@qamarwali]

5 u = 5 micron (micrometer). So 5 um is a small scale as compared to 100 um. But it is bigger scale as compared to 5 nm, where n is nano Simple is, if we decrease the scale, we can see more depth analysis of the material

[@organiccookingmore9071]

can you explain topography of these SEM images plz

[@qamarwali]

Yes topography or morphology means that how it looks like or what is the shape, size etc... There images seems like spheres or nanoparticles and surface looks rough.. I hope I answered

Asalamualikum sir can you help me in interpreting the SEM images of a pasta sample?

[@qamarwali]

It is very easy. Just see the SEM images and observe what information is there. For instance, what is the shape of structure? Nanoparticles, nanorods, sheets, sphere... What is the size of the particles or sphere ? What is the size distribution? It means whether the particles are distributed uniformly or varying in size. Just find out the average value. Observe whether the surface is smooth or rough and then find the grain size if possible. Look for the porosity and observe the pore size in the materials.....then link it with the specific surface area (m2/g).... Generally, SEM provides the above-mentioned information ......and you need to elaborate these points in detail to make a paragraph in the research paper or thesis writing

Sir if the particle size is 119nm means it's considered as nanoparticle?

Sir plz reply soon

The standard definition of nanomaterial is when at least one of its dimensions (x, y, and z axis) are in the range of *1- 100 nm*. Some other reports stress that *below 1000 nm* is considered as nanomaterials. Anyways, your materials dimensions are close to 100 nm, so it is for sure nanomaterials. Congratulations 🎊

@sonalipatil262 As I explained already that if it is under 1000 nm, that can be considered nano. Still, your particle size is very close to 100 nm side, so I am confident that it is nano. How do you measure the size? May be in other dimensions, it shows much smaller value ?
