Just for myself as an example, I finished my phd in applied physics a few months ago and, long disillusioned with the academic route but not wanting to stray too far from the technical, I applied for and eventually got a job offer with ASML in the Netherlands. It's a design and engineering...
(Put in a lot of context, and post is long now. Question and TL;DR are at the bottom!)
Recently finished my PhD in Physics: X-ray spectroscopy of transition-metal crystals, a lot of soft X-ray synchrotron and solid state science, vacuum science etc. I knew after a few months of starting the...
Hi,
So I applied for a postdoc position for a research lab in France. In my cover letter to the PI (who's English) I wrote at the end:
"I will call you next week to make sure that you received my CV. Thank you for your time and consideration."
I received an acknowledgment of my application...
So I usually use VESTA to make my figures, and though the new version is able to do many mad things with calculated electron density isostructures and whatnot, I can't seem to just be able to throw in some clover-leaf d or p orbitals like what was done in the image below (from this paper on...
So the basic understanding I have of electron transitions for EDX, XES and other x-ray fluorescence techniques is that a transition from:
L to K shell is named K\alpha
M to K shell is K\beta
N to K shell is K\gamma
M to L shell is K\alpha
etc.
Grand, easy... google leads me to multiple diagrams...
Thanks... initially that sounded great (get software to do it for me) so I took your advice. However, now it seems like it'd be quite a bit of overkill and a time-sink. I borrowed a copy of Spartan there and had a good play with it. It doesn't really appear designed for constructing bulk crystal...
Hi,
So I'm a phd student of physics, but my research overlaps a little with inorganic chemistry, specifically transition metal oxides and spectroscopies of them. I can glean some information MO diagrams and find them quite useful when writing about what I'm doing... however it's difficult to...
I don't quite see what you're getting at. It's static so the only force is gravitational, which is radial. Imagine the column as being very thin and pointing in a radial direction.
Good point, that didn't occur to me. But look at it again, it actually does equal zero when r=R. The bracketed part goes to (1/R - 1/R).
Hmm I'm pretty confident in it now. What do people think?
Hmm.. not sure why this was moved, it's not homework, I've actually just graduated. It's something I was debating with a friend.
Okay I see how it doesn't work as it assumes g is constant.
Okay back to basics, let me try again.
Pressure is force over area, in this case "weight" over area...
Okay obviously a hypothetical situation, this planet has a radius R, uniform density, and it doesn't rotate.
Pressure in a liquid is given by
p=\rho g d where d is the depth.
So the liquid pressure a distance r from the centre of the planet is.
p=\rho g (R-r) (where r<R)
But g is also...
Thanks guys, you really helped me with making a more informed decision. I let the two supervisors know I was still deciding between them, but in the end I went for the spectroscopy one. I still have to apply for it and go through all the red tape, but it looks promising.
Cheers

Hi, so I've just finished my final undergrad days in physics. I've decided to stay on to do an experimental phd in the same university, as I've a scholarship that will make it more financially viable. I sort of put off the decision so as to focus on the final exams, and now most people in my...
