Thanks for your input. I've considered that suggestion and I think it's viable. Here are some SEM images of microcratering in a similar vein that are fairly interesting. http://ccldas.blogspot.ca/2011/05/more-sem-images.html

Hey all, As the title suggests, I've found some recurring structure on an SEM image and I can't for the life of me figure out what it is. I took the image this morning. Here she is: http://i.imgur.com/nFuBsW2.png Here's a larger, more zoomed out and higher res version. A few more of...

Hi all, I've been toying with an idea lately and I'm wondering if any of you could help me out. Is there any method you know of to heat an area roughly 5 nm in diameter? I've thought about laser radiation for a while, but of course we are limited by wavelength. 5 nm would force us into the...

Hi there, I'm looking for some information on the current limits of the beam width of currently available lasers. I'm less interested in experimental setups that are not on the market yet, but I suppose if one of them is markedly different it would be interesting to know. Specifically...

Hi there, I'll try my best to be descriptive. I'm looking for as much information as possible on the limits on current technologies in producing copper circuitry. I had a nice conversation the other day with a member of my research group and he was telling me about the demand for the ability...

Thanks for the information! Does anyone have any idea what current we might have to drive this at? I've been told pules will have to be around 300-600 V but I can't get a stable reading of resistance for the transducer. It fluctuates wildly between 0 and 300 ohms...

Thanks for your reply! It has been very informative. The function/signal generator that I have has a pulsed mode (effectively a square wave, right?) What you've said about water is interesting, I didn't mean I would submerge the probe entirely, just the end of it to get some verification of...

I wish I had a datasheet for you, but I've gathered all that I know so far. It was purchased of Amazon (from China.) Keep in mind we only have the probe, no electronics with it. This was listed on the amazon page: Frequency: 5MHz Crystal Diameter:12mm Measuring Range:3-200mm ( in Steel )...

Hi everyone, I've acquired a cheap ultrasonic probe (advertised as for a thickness gauge.) It's a temperature resistant probe up to 300C and operates at 5MHz. It came with no documentation or means to drive it. It terminates in two LEMO 00 connectors, and I've acquired 2 LEMO 00 to BNC...

You're right, I do have a funded offer for this summer. I am almost definitely going to be taking that position for this summer, I am mainly asking for the future. I still have two full years left as an undergraduate and would really like to plan ahead. I'm also lucky enough to be part of a...

Hi friends, I realize that my question is probably not particularly clear cut, but I would like to hear some opinions on it. I am wondering, is it better as an undergraduate to diversify your research experiences, or to specialize? Would it be better to try out a number of different fields...

Hi guys, I am currently trying to figure out the best way to create a target of deuterated polyethylene for neutron detection. I have ~30g of this very expensive powder and need to determine the best way to create a thick target (thick as in ~5cm, not a thin film like is used for proton...

Well if you read their website in order to fill the app, which you presumably did, I wouldn't worry too much. If you liked what you saw about the program it doesn't really matter what school you do it at, right? The program should be exactly as it was described. I guess location/campus will...

The deadline to apply has passed for most. Many of mine were due ~Feb 14th. From what I've seen on websites, it sounds like most offers will be made beginning late February, but some could still come out as late as April.

I applied to 6 REUs and one internship. - UMichigan CERN REU - Not accepted - Rice NanoJapan International REU - UC Davis REU - Old Dominion/JLab REU - Rice Quantum Institute REU - Idaho State REU - Passed "preliminary" selection I also applied to an internship position with Lockheed Martin...
