7.1 | MSE104 - Diffusion, Nucleation and Growth

[@mcleanb981]

Im in my final semester of my program, and this is the first time I've ever received a good lecture on this. Your lectures are fantastic and your students are lucky to have you.

[@sdanielmcarthur8613]

Amazing explanation, understood the concept clearly. Loved it!

This video saved my life thank you so much you're a great teacher!

[@MoeMoeStudio]

How can you not like this guy??

[@Selma-im9er]

you video saved my semester

[@alexandernellessen4398]

simply love listening to you...

A quick remark: in the Arrhenius expression of diffusivity D=Do*exp(-Q/RT), Do is not the diffusivity at the absolute 0, it is instead the maximum diffusivity that you obtain when temperature approaches an infinite value

may we please have some lectures , we really like the methodology used .....proudly NUST students

[@yjasper8411]

you explained that so much better than my professor :(

In 28.18 and 28.27, Prof. Dye actually means to say w* goes up -- not down.

[@gsmysteries223]

Thank u sir for making me clear🙏

[@iPlayZone]

W = + 4/3*pi*r³*delta_G_v+4*pi*r²*sigma, Delta_G_v = G_solid - G_liquid < 0 hence negative! Also r* = - 2*sigma/delta_G_v. W* is right, but only because you copied the right answer :D.

very good explanation...

[@nagoenes]

Why is gas constant here? There is nothing about gases but it appears in equations anyway.

[@yuangfu5023]

is there a mistake in this video that the added strain energy should increase the W* rather than decrease?

[@bksaif]

In 5.43, l_ave ~ sqrt(D*t)..... Isn't D that depends on the jump or frequency rate, and not t ?

[@noondonporn9710]

Your lecture is so good. I want to study master degree with you

[@burcmm]

Actually, does not strain energy add to the total nucleus energy? Then this will make the stabilization of a nucleus even more difficult, yielding a larger critical radius (with the assumption that all the strain energy is accumulated in the nucleus). Thanks.
