I have to determine my unknown which is measured by SEM and EDS. My unknown is polysulfone. In one EDS result, I have 4.4% of Si?

I am wondering that do I need to consider about Si in my unknown? My unknown sample is polymer, so it is mounted on aluminum stubs using epoxy and coated with a thin layer of Ir (~5 nm)....

Comparing Liposome Size: DLS Measurement vs. SEM Observation with Air Drying ?

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.

Dear you can visit RG for me ,so I written for this subject and meet to our idea

Ah M Kamal

Count/measure the number of a specific element that is identified by a model. Let two model identifies n1 and n2 elements from total n elements. Compute the value of nn1=n1/n*100 and nn2=n2/n*100. Then the ratio is nn1:nn2.

Hi Al, do you have any papers related that show your formula? I want to get more information about it as well?

Thanks
