anyone know if Insulating & Semiconducting Glasses (Directions in Condensed Matter Physics) is worth the $105 Used price?
<Noxz>
not on libgen
<Noxz>
it was in refereince on the Caesium Oxide wiki page
<Noxz>
for specifying it is a good electron emitter but it's high vapor pressure limits its usefulness
<Noxz>
MP of 490 C, so not sure why vapor pressure would really matter unless they crank up the temps
<Noxz>
(I'm looking at electron emitters)
<Noxz>
and from the MgO secondary emissive paper I read on using Mg(OMe)2 dip then in an oven, I bet something similar could be done with Cesium
<Noxz>
no need to boil metals
<Noxz>
only need to evaporate the methanol off
<Noxz>
which is done in air, so Mg(OH)2 does form, and the dehydration of that leads to MgO
pie_ has joined #homecmos
<Noxz>
makes prepping samples fairly simple.. and no need to store reactive metals on hand.. though CsOMe isn't exactly non-reactive, it's likely much less, and the by product of moisture getting in is just the CsOH + MeOH
<Noxz>
but yeah, the area I am looking into is electron gun/emitters
<Noxz>
the main issue I see with both CsO and MgO is that they are reactive towards water forming the hydroxides again.. sure heating it will create the oxide again, but that seems a little -meh-
<Noxz>
but, the prep should be super simple
<Noxz>
cant always have a vacuum...
<Noxz>
I was actually working on the math required for the work function/eV if Mg (MgO) could be used
<Noxz>
looks like in most (all?) cases the oxide has a higher work function
<Noxz>
also, instead of a nickel screen with MgO for electron amplifier, what about nichrome
<Noxz>
that way it may be able to be easily heated to make the oxide pre-run
<Noxz>
(the plan is a series of MgO doped nickel-based screens)
<Noxz>
"A High Polarization and High Quantum Efficiency Photocathode Using GaAs-AlGaAs Superlattice" is one paper i am basing off of
* SpeedEvil
has just been reading shit medical papers recently.
<SpeedEvil>
It's annoying.
<Noxz>
for amusement or for work?
<Noxz>
I have to migrate some MySQL sotred Procs into java for work :/
<Noxz>
stored procedures*
<SpeedEvil>
For trying to campaign for proper treatment for my illness.
<Noxz>
doh, being sick is no bueno
<Noxz>
pie_, I also hang out in pound pound chemistry and have my own fumehood and junk, so I run experiements from time to time
<Noxz>
or at least I did before moving.. and have come to the conclusion that one room that was just going to be an empty room will have to be my lab because tha garage isnt bgi enoug
<Noxz>
I did not like the idea of stinky solvents inside the house though
<SpeedEvil>
positive pressure!
<SpeedEvil>
err - negative
<Noxz>
heh... the fumes have to go somewhere
<pie_>
<Noxz> I read papers for a week
<pie_>
oh ok lol itd not completely hopeless then xD
<Noxz>
it's been a week or so
<Noxz>
I knew nothing of electron mutliplication before
<Noxz>
and came across MgO which was easy enough to find info on
<pie_>
Noxz, why not the shed as storage tho>
<pie_>
not shed lab just shed storage
<Noxz>
I actually really like the idea of using a nichrome wire mesh dopped in MgO
<Noxz>
I do have a small storage thing outside
<Noxz>
but it's not really adequet.. and not really hidden.. imagine watching someone pulling out bottles of reagents and what not
<Noxz>
prefer to give people no ideas
<pie_>
have a box
<Noxz>
"The photocathode was p{doped to allow a negative electron a±nity (NEA)
<Noxz>
surface to be achieved upon deposition of Cs and O2"
<Noxz>
maybe
<pie_>
magic item transfer box
<pie_>
:D
<Noxz>
I would still be opening up the bottles inside to measure
<pie_>
even better, make a pneumatic tube system so when evrything blows sky high the toxic fumes can waft into your house
<Noxz>
my exhaust system before was decent
<Noxz>
from the fumehood
<Noxz>
going to be similar yet
<Noxz>
not like much has changed, beyond the geometry
<SpeedEvil>
Noxz: I'm building a new small insulated building as a test - aimed at hermetic sealing, with air-air heat-exchange.
<SpeedEvil>
take this, flow air one way through one sheet, and outlet air the other way through the other sheet, and get a decent countercurrent heat exchanger for air
<Noxz>
somewhat interesting, in that paper they use a ~750nm laser.. so edge of infrared, likely around 1.65 eV, yet Cs (not CsO) has a work function of 1.95eV .. which is actually pretty close
<Noxz>
SpeedEvil, I plan on buyging an ERV for my house
<sync>
I wouldn't be worried about solvents, there are far worse things
<Noxz>
SpeedEvil, so I know of the structure of the 'core' a little
<Noxz>
for ERV, where moisture is kept more constant, it's made out of a paper like material
<Noxz>
sync, I have Lithium, Sodium, and Magnesium metals
<Noxz>
those are kinda nasty to house outside
<Noxz>
lots of volatile solvents though
<Noxz>
ether, dcm, methanol, etc
<Noxz>
not exactly unsafe, just volatile
<sync>
I have reactive metals in a desiccator
<Noxz>
most if not all of my Lithium is in Anhydrous oil
<Noxz>
the Na is individually packaged in 1oz packs
<Noxz>
and the Mg is fairly safe, just keep it away from a flame
