Teaching Experience

I am currently a Teaching Assistant at Georgia Tech for Electronic Materials Course. I have also had past teaching experiences in tutoring students for math.

Extracurricular Interests

I am from India. I did my undergrad major in Polymers and minor in Chemical Engineering. I am currently a PhD student in Materials Science and Engg at Georgia Tech and my research is focused on materials for integrated circuit packages. I like playing chess and many outdoor games especially cricket.... I have had a great teaching experience and I always encourage students to push forward to achieve a extra bit than others...

Someone asked:

.) A two-level system has a ground level with four degenerate states and an excited level with two degenerate states at 600cm-1 above the ground level. What fraction of the molecules are in the upper level at T=0 or 1 K?
ii.) If we ignore zero point energy corrections, why are the vibrational partition functions close to one at room temperature (physical reason, not just math)?

Nair responded:

Please find the attached answers and try to understand the general concepts of statistical thermodynamics from this which will help you in solving other problems as well...

Someone asked:

For a metal matrix composite of SiC fibers in a Nb-20 wt%W matrix, determine the following.

1. Calculate the density of SiC, which forms the zinc blende (ZnS) structure with a lattice parameter of 4.36 Å

2. Calculate the density of a solid solution of Nb-20 wt% W. The solution is BCC with rave = XNb∙rNb + XW∙rW, where XNb and XW are the ATOMIC fractions of W and Mo, respectively. The atomic radii of Nb and W are 1.43 Å and 1.37 Å, respectively.

3. Calculate the VOLUME percent SiC in the composite if the MASS % SiC is 25 wt%.

Subject: Pre-Algebra

InstaEDU asked:

What is Pre-Algebra?

Nair responded:

Study of numbers, decimal fractions, ratios ,etc.. that help you to build fundamentals to solve the complex problems of algebra....All these are very important and also much fun...


Subject: Geometry

InstaEDU asked:

What is Geometry?

Nair responded:

Geometry is the study about shapes and so is much fun.....A very interesting subject to study where once you learn the basic theorems you can start designing new shapes; apply those theorems and find interesting results ...Its all about playing with Math...Explore your creativity....
