Beautiful presentation with beautiful content... Thank you, Master.... Thanks a lot...
Thank you sir, very good and correct explanation sir
great job....
Beautiful Explanation Thanlkyou SO much
Really appreciate your feedback.
Thank u sir
Good work
Thank you...
Thank you for the video. It is very educative. Please how can I use it for pore size and volume?. Thank you
Thank you for your comment. I think it's better to use BET analysis if you are using porous materials. Even though SEM can provide Z-Axis data using the greyscale, you can not accurately calibrate it. Without the Z-axis, you can't discuss volumes. You can measure pore diameters (and areas) using this method. If you want to get Z-axis details and obtain volume information, use Gwyddion, and you may get some values. I'm not sure about its accuracy.
Dear Master,
could you please make a video regarding the XRD peak analysis, EDS spectra analysis? If it understanding means I'll feel comfortable in characterisation. Kindly accept my request.
Thank you in an advance.
Sure. I'll make some videos regarding those characterization and related softwares. Thank you for the suggestion.
thank you so much , please unit of particle size ?
Since we input "nm" as the unit, it will give all the dimensions in "nm".
@@amc-tec7721 ok thnak you 😇
how to take images which are in pdf format.
You can simply import images that are in PDF format to Photoshop. Then you can save it in an acceptable format. Or you can use online PDF to JPG converters.
how to color sem images
You can do it by Image>Color>Channel tool and in the window, select "more" button. From there you can change. But I highly recommend you not to do that. Keep the standard gray scale in SEM images.
@@amc-tec7721 great... thank u Sir
