I need your suggestions. I am using HF, HCl and DI water soln. as etchant but after etching process, the weight of sample obtained is higher than that of initial? What could be possible reason??
Did you measure weight of completely dry sample? such as vacuum filtered film, vacuum oven annealed powder, freeze dried sample, drying in desiccator, etc.? If you measuring the weight of a slurry or sample dried not entirely there is water still trapped between MXene flakes that is not possible to get rid of entirely after concentration, this is what could give you extra weight.
It's a paid web-based 5 days course. The course is held twice a year. Next session should be in 4 to 5 months. The information for registration will be available prior to the next session at nano.materials.drexel.edu. In order to access lectures registration is required.
Very much looking forward to this course! Will hopefully be a very interesting and informative week :)
Thanks a lot for your interest!

@@a.j.drexelnanomaterialsins5931 Okay, thank you much Sir❤
Hello sir . when will your next session start please
When MXene in colloidal solution oxidizes into oxides, what happens to the functional group?
are you having any more of these style of events or is there a place I can watch the recordings?
can i access to the lectures . when will your next session start?

Can i still the join the course or get access to the lectures ?
We launch new course in February 2023 check nano.material.drexel.edu for more details
Could you please provide me a cif of mxene?
try materials project web site it might be available there
