Thank you so much sir for nano physics playlist,very nice explanation sir you are genius, please sir continue these series Again thank so so much very easy explanation 🙏🙏🙏🙏🙏🙏🙏
When I saw ur first lecture. ..the very first thought came into my mind .... Is.alakh sir......ur teaching style is similar to him...this is my personal opinion I am not comparing
Sir thank you so much before exams it helps a lot for revision. Sir one small request please add the part of mechanical property too. thank you once again sir.
Metals mein kesy increase hoti hai jb k metals mein bhi tu discrete hota hai... Aur electrons jo hongy already just wohi conduct kr skty hein nechy se oper jany k lye unhe bhi tu energy Ziada chaye hogi just like in sami conductors ??? Ans kindly
Electrical properties Electrical properties of nanoparticles discuss about fundamentals of electrical conductivity in nanomaterials. The increased perfection such as reduced impurity, structural defects and dislocations would affect the electrical conductivity of nanostructures and nanomaterials. The resistance of the material which is due to opposition to the flow of electron by atomic collision decreases when particle size decreases and hence its conductivity increases with decrease in particle size of the material. While, exceptions are the metals where conductivity decreases with decrease in size of the particle..... this given in my book opposite to video
Agr wettability inversely proportional hn contact angle k and size reduce hone pr contact angle increase ho raha then wettability decrease honi chaiye means size and wettability directly proportional ho gye.?? Pr vdo m inversely proportional bta rkhe end m
Sir mere 13 th March ko physics ka semester exam hai hamare clg ke teacher ne kaafi alag likhwaya hai properties mai agar mai aapke saare points likh du tho aache marks mil jayega kya?🙏
Sir wettability Isn't clear... You say that size decrease.... Contact angle increase.... Again says that contact angle increase means wettability decrease.? How can it possible.?
sir please mra defence h m.phil chemistry ka topic'' hydrothermal synthesis of MnO2 nanostructures for rechargeable lithium ion batteries ha'' sir is ki presentation kesy bnaon help kr den.
Vhiya if contract angle increases watability decreases. But if perticle size decreases watability increases... This two is contradictory thought... Plz clear this.
No teacher can explain this with so much simplicity...u r the best
There is a slight mismatch in the last point of wettability in relation with particle size
he has the skill of the true teacher, he who makes things simple to others understand , good teacher,
Very nice lectures sir.
All concepts are cleared. 🙏
you have a good qualities of teacher ...i know your channel will be grow surely on UA-cam ....best wishes to you ✨ ..keep it up ...☺️
Oo
Good
❤great sir
Thank you sir for this playlist.
And keep it up your teaching skill is awesome ☺️
Great teaching method
Finally i understand nano physics for this playlist..tnq so much sir ❤❤❤
Thanks sir for such wonderful videos. You help me so much for prepartion of exam
Excellent session... really great job sir .. keep shining 😊😊
wow it just amazing lecture☺️
Great teaching sir....❤❤
Good explanation of physics 🥰
Thank you so much sir for nano physics playlist,very nice explanation sir you are genius, please sir continue these series
Again thank so so much very easy explanation 🙏🙏🙏🙏🙏🙏🙏
Amazing explanation sir ✨... And Happy teacher's day 😊 sir🎉
Thankyou so much ☺️
Very nice explanation.
Nicely explained in a very simple manner. Really good. If possible plz explain the magnetic property of nanomaterials in detail
thank u very much sir
complete the whole playlist
As soon as possible
I wish your skills get more exposure sir .. thankyou sir for fruitful session again 😊💯👩🎓
thank you so much sir, u have explained it so well and even the notes are also very helpful. plz keep on posting always.
Very nice lectures ❤
I have found till the best teacher on UA-cam ❤🎉
Thank you sir for such a precious video. How to explain the reverse saturable absorption in 2D materials.
Best explanation ✨
thank you so much for this precious lecture
No words for your explanation sir
nice
you are amazing sir😀😀😀😀...

Sir thank you so much before exams it helps a lot for revision. Sir one small request please add the part of mechanical property too. thank you once again sir.
Best teacher
Thank you sir. Please suggest some books to read this topic.
sir bakio se bdia smjhare ho aap aur sbse achi chij aap smart board use ni krre❤❤❤❤
Thank you sir 😊Jay hind 🇮🇳
thank you very much sir🥺🥺
very impressive
Metals me bhi tu band gap increase hoa frr conductivity km hony ki bjaye increase kun...plzzz expkain
Sir Thank you ❤
Sir can we include nanoparticle as a class of nanomaterials
thank you sir

11:36 here... 🙄
Please clarify
yes mere notes men b Ulta likha hai. It's written semiconductors ki conductivity increase hoti hai when we go to nano size
Same
Wettability is proportional to particle size . at 39:22
Your lecture is stunning.
Is there a Contrast between you talk about Wettabilty and partical of size !!
Will the boiling point also decrease?
Sir muje CCS university ke. MSC physics 4sem ke solid state physics ke notes chhye sir 4 July ko exam ha mere khi nhai mil re notes please helpnsir
Like alakh sir 😅❤

Sir mere 13 th March ko physics ka semester exam hai hamare clg ke teacher ne kaafi alag likhwaya hai properties mai agar mai aapke saare points likh du tho aache marks mil jayega kya?🙏
Yes definitely
In matals the electric conductivity decrease with decreasing the size. Isn't it?
Yes
@@rkphysicspoint sir kya bol rahe ho
Ek baar sahi bata do?
Didn't get the point of contact angle connection with particle size , check pls.
Ok i will check
@@rkphysicspoint please clear this point sir🙏
👌👌
Sir band gap kyu bdh jata h nano range me Jane se
sir but staright line angle 180 hota ha ap ny zero degree kis tarh kaha
sir can ye please tell reference book for the following
Sir wettability Isn't clear...
You say that size decrease.... Contact angle increase....
Again says that contact angle increase means wettability decrease.?
How can it possible.?
Why electrical conductivity increases in metal
Same qs..I also couldn't understand it..
Sir nano technology ke topics ki theory bhi krva do
Please 🙏
Ok
sir please mra defence h m.phil chemistry ka topic'' hydrothermal synthesis of MnO2 nanostructures for rechargeable lithium ion batteries ha'' sir is ki presentation kesy bnaon help kr den.
Coercivity increases.
Sir notes bhi provide krwa dijiye🙏
Ok i will try
Vhiya if contract angle increases watability decreases. But if perticle size decreases watability increases... This two is contradictory thought...
Plz clear this.
same problem sir, please clear this
Size ko ghatarhe he lekin kiski size ko ghatarhe he sir o to batao
Any material, like metal and semiconductors
sir refernce book for this please
Ur saved playlists are visible
Please provide notes
Sir apne notes theek kejiye
Great skils sir....... Falling in love with nano because of you🥹💗
I was thinking that in metal electrical conductivity will decrease with size
