When that happens, you can try recrystallizing the dilithium by immersing it in an inverted positronic field for a few hours, as long as the dilithium isn't too far gone. YMMV.



That only works when you have slingshotted around the sun.

So here are a couple of pictures that I collected when I was learning to work on our Scanning Electron Microscope, SEM.



Wow! Those are amazing - thanks for sharing them.

And to think that I almost skipped over this thread because the title was nonsensical. I would have missed out on a good one...

Worked with a TEM, XPS, Auger, when I was an undergrad. I mainly do thin film processing. E-beam and thermal evaporation, sputtering, RIE etching, chemical etching, Furnaces...that sort of thing. Our SEMs and the new ESEM are used mainly for direct writing, patterning of our devices....but we use it for testing too.

see now that's just hot... I worked for a company that manufactured High Purity sputtering targets as a college student...

then Spent some time after that doing Hard Drive thin film research (CoPt alloys) at Carnegie Mellon in Pittsburgh... (I like magnetic materials but they don't sputter well...) I was actually doing more Differential Scanning Calorimetry (sp) then film deposition... The real trick was removing the film from the substrate (we used a concoction that included Hydrogen Floride (HF) not something you want to play around with...

Most of my experience with SEM was Failure analysis though...

of course now I'm just playing with lasers... (nothing exciting or anything... :P)

:D:D:D

I'm thinking that after you sputtered on the target, it wasn't exactly high purity anymore.:)

Cool pics, I used to play around with SEMs when I was a kid. Of course it helped that my dad was involved with designing some of the first SEM at Argon National Labs & later at a company he started in Sunnyvale, CA in the the late 60s (Coates and Welter Instrument Coporation)

Now look at me, I jump out of planes......

We have recently been using HF a lot! It gives me the creeps, I hate it! I keep trying to tell my boss that my mom told me not to play with chemicals....but somehow I don't think he really cares [:/]



Please be careful!!!!

I know more than one person missing fingers because of that stuff. Make sure you have all the supplies you need to treat HF burns around.

Yes we have everything we need. We are fairly careful here....especially with that stuff. :S We have all kinds of other chemicals too, but that is by far the worst.



and don't let lesley tell you that you can't come work for me if we get funded....

:D:D:D

"I love the smell of Hydrogen fluoride in the morning."

Quote


Hydrogen fluoride is toxic to the human body and can be fatal if even small amounts are ingested or absorbed through the skin. HF burns require immediate and specialized medical treatment. HF acid burns are not similar to burns produced by hydrogen chloride (HCl), or other common acids. Onset time of symptoms of HF burns are proportional to concentration. Above 50% instantaneous effects are apparent. Between 20% and 50% clinical symptons may not appear for one to eight hours. Concentrations below 20% may not result in symptoms for 24 hours.

Entry routes include inhalation, ingestion, skin and eyes. Aside from burns to the eyes, skin, lungs, or digestive tract, the lowering of serum calcium (hypocalcemia) is one of the most serious consequences of HF exposure. As the free fluorine ion penetrates the skin it binds serum calcium forming cellular calcium fluoride (CaF). This has effects on nerve conduction and can lead to extreme throbbing pain, metabolic changes, and even death.

to give you an example -

you always double glove when working with HF. We had a guy from Zimbabwe (know it all fucker) that didn't double glove. He had a pin hole in the index finger of the left hand glove. Idiot stuck his finger in the HF...WHY? we don't know but it for a brief second. Result? He's missing his index finger on the left hand from the acid that got through the pin hole in the brief second his finger was in the acid....

don't be that person....
