thank you alex for your post :-* ... i have stumbled across this piece before:
http://sine.ni.com/nips/cds/view/p/lang/en/nid/14604
its price is acceptable, yet do you have an idea about for how much is the LabView soft :o ($800+)
also on mc a piece like this...
need something with a resolution higher than 12 bits and a sampling rate around 1-10 MHz for the cheapest possible price ???
any suggestions would be appreciated!
I answer this ::)
well the pristine PANI should exhibit a conductivity in the magnitude around 10^8 .. well but that's not all .. i'll further need to optimize the suspended phase volume fraction and the physical dimensions of the composite block in order to optimize the current magnitude.. ...
;D lol
well, someone advised me with measuring the shot-noise phenomenon, by the use of a current integrator.
and this idea is so appealing to me, sounds like it takes down the measurement process to the edge.
have found much circuit schematics for this though, yet i wonder which particular...
:-[ yeah but even the low accuracy synthesis of a preliminary goo would require a specialized polymers lab, you know .. goo can't be prepared anywhere but in goo-labs :(
:D well i first got to theorize the whole thing from synthesis to advanced testing before i get granted access to the lab inwhich i'll be able to make that goo :-[
i was just reading this .. http://pdfserv.maxim-ic.com/en/an/AN2236.pdf
sounding like if i succeeded in turning my very minuscule current into voltage then i'd be able to simulate that PIN diode in the circuit .. and hence gain such precision .. right?
but how :D ??
Well ,,apart from any quantum or coupling efficiency .... what if we assumed to have an ejected photo-electron inside a polymer ... what circuit should be most efficacious in sensing such freed electrons and what would be the minimal sensitivity of the detection (the least number of ejected...
yeah i have been reading relentlessly lately about practical evaluation of such theories like EMT, percolation, maxwell, pal model, etc... and all what i have found was an unbelievable lack in generality for such laws being very case-dependant with paradoxical behaviours for many composite...
yeah, decimal points
have looked up for precision resistivity measuring devices and they provide no more than 4.5 digits display with 0.03% error, which is not good and not as portable as i wish they are very bulky indeed :'(
the polymer's conductivity ranges from 10^-8 to 10^-11 , depends on...
yeah ..now you understand me ;) .... I am after making a circuit that could measure the value of photoemission or any related value to it with 7-8 digits of precision like conductivity, avalanche effect, etc.
Apparently you have misunderstood me :(
first concerning the uniform electric field .. well thats partially right .. i need to have conductors at each end of the polymer so i can somehow measure the conductivity of the composite/polymer... so yes i'll someway or another need to implement an...
