Hello, I have a PhD in computational material science and experience using such computational techniques as Density Functional Theory and classical Molecular Dynamics. I would like to pursue a career in the private sector rather than in academia, however I found out the hard way that the...

Some metal give two yield point in stress strain diagram. One is called Upper yield point and Lower yield point. Why lower yield point is considered as more reliable. I can think of Upper yield point is much more dependent upon experimental apparatus settings. So why lower yield point is much...

Hi All! Haven't been here for some time, the changes are looking good! Anyway, formalities aside, I am having serious problems sourcing and implementing a suitable stainless steel (Grade: 304; thickness: 0.3mm) substrate for my etching process. I'm currently working on developing a...

Well what I want to ask is that If someone does graduation in material science. SO WHAT kind of job he/she gets.? Infact what is material science what is being studied in this subject.?

Let's assume for a minute that money was of no concern. If one has a 10 MPa external environment and needs to have vacuumed-out spheres (or 1 atmosphere, close enough to call vacuum) inside of that environment. In particular, I was thinking of a sandwiched lattice of maraging steel, with it's...

I originally posted the following question on physics.stackexchange, but no one was able to answer it. I did find this answer on PhysicsForums, but I was already aware of the oscillation of electrons in response to an external electric field. What is the physical cause behind a material having...

Is it possible to switch the porosity of any microporous material by external stimuli (eg. optical, pressure or electrical ). I'm trying to imagine something akin to an "Artificial Stomata" where the pore opening & closing Can be externally controlled. I'd be very thankful if someone could...

So I'm looking for how tall I could make a tower of concrete, using any reinforcments, in an environment of only gravity starting at sea level. Could it get so tall it'll own gravity would effect it, the moons, or the sun's gravity, or would the bottom give out will before that?

Hi all again, I started a post earlier and it was buried somewhere by now. I really need more input and information and hope you all can help. How are admission process different, CM vs MS&E? CM belongs to Physics department while MS&E is usually on the engineering side. I got my Physics...

Hi all, thank you for your attention I graduated with a B.S. in Physics just 2 months ago. I went to an American public school with good reputation in Physics. I sent in my applications for the Fall, 2015 Ph.D application cycle last fall. However, I failed to get into any PhD programs, mainly...
