The 7-minute explanations I cried to know, but I did not get from my prof. Thank you, Sir.

I am happy it helps. Wish you all the best 👍

Dear sir , in all of the four materials which should have high specific surface area and why? thank you

[@qamarwali]

It's simple. Smaller the size of the nanostructured materials, larger the surface area and vice versa. If we decrease the size of any material, we are basically exposes more of its surfaces that is why it has more surface area.

[@ahmedismail8867]

@@qamarwali Thank you for your reply, i am stuck in a situation where i have been asked that why 3 dimensional material has high surface area than 0 dimensional nanoparticles. The 3 material particle is in micro scale while for 0 dimensional material it is in nanoscle but bet result suggested us that 3 dimensional material has high surface area. Thank you

[@qamarwali]

@@ahmedismail8867 just make it more simple. Take same amount (suppose in mg) both 3D and 0D. Which one will have large specific surface area (unit in Square meter/gram)? Definitely the 0D willl have far larger surface area than 3D.

[@qamarwali]

Summary: More surfaces exposed leads to large surface area. 0D particles size are smaller than 3D so the former exposes more surface area thereby large specific surface area.

can u provide the link of sem images used and any journal which says about this classification

[@qamarwali]

It is available in many literature documents. Just google, you will see detail. The SEM images are my own research during my PhD

Sir, firstly you took nanoparticles as an example of 0D, lastly as 3D. If we look at definition of nanoparticle the last example contradict the idea. To be nanoparticle it must exist in size of 1-100nm at least in one dimension.

[@qamarwali]

I agree with you. 3D means all ranges are out of nano range which is below 100 nm. I just include it here because most of the time we are talking about 0D, 1D, 2D and 3 D.

[@starfood5729]

Sir . What ways do we have to protect 0D 1D 2D structured materials? for example : 1D materials used to manufacture electronic circuits have encapsulation methods . So is there any other similar way ?

[@qamarwali]

Every type of materials have applications. For instance, graphen which is 2D have a lot of applications in battery and supercapacitors

[@starfood5729]

sir, thin film solar cells will lose efficiency in hot and humid conditions. So is there any way we can prevent or reduce the penetration of moisture into the solar cell?@@qamarwali

Hii..,I have doubts about nano materials how can I approach you..I can't type here .. because I have lot of doubts about this subject.please help me to clarify them.

Just write here. No issues, it is an open forum to discuss research related stuff. Please!

thanks very much very informative video . I love it soo much

[@nanatv1507]

Sir, must the AFM thickness (z- axis) of the 2D nanosheets graphene strictly be less than 5 nm? Can it be above 10nm, so long as under 100nm as you mentioned? Thank you Sir!

[@qamarwali]

It should be less than 100 nm if want to call it nanoscale. At least one dimension must be below 100 nm then it is in the range of nanoscale.

[@nanatv1507]

@@qamarwali I see, thanks Sir! My AFM thickness for my reported 2 D nanosheets is actually 15 nm from the height profile analysis. However, as I read a few papers, all of their reported thickness for 2D nanosheets falls under 5 nm. That's why I'm worried if the reviewer will question my AFM result in my manuscript.

[@qamarwali]

@@nanatv1507 your sample is already in the range of nanoscale

What do you mean by nanochemistry 😊

[@asst.prof.rohitnikam729]

Sir in another video of xrd interpretation of intensity less or more. You have mentioned about atomic density along composite plane. Is it calculate atomic density by mass to volume ratio. Please advise how to calculate atomic density along composite plane in XRD graph.

[@qamarwali]

I am not sure about your question. However, density of plane matter a lot. Higher density high intensity and vice versa

[@asst.prof.rohitnikam729]

@@qamarwali sir how will I able to calculate density of plane. How I decide density of plane is less or more

[@qamarwali]

@@asst.prof.rohitnikam729 I think from intensity you can easily derived. There might be some other way to calculate
