previously I described how an inkjet printer with 16 element cartridges printing at 9600 DPI could deposit the chemicals used to make perovskite photovoltaics, then it could be reacted to produce about 9 million different chemical variations.
Then, this sheet could be overlain with a gel that has
Ph color changing chemicals, Illuminated with a scanning laser, whenever the voltage was higher the mini gelspot would turn a brighter color permitting a laser scanner to find the highest voltage producing chemical out of 9 million. As to producing current I think the size of the reactive color blob would suggest current. This is a kind of alternate method to the milliken oil drop version here.
Just 12 10" x 10" sheets would permit more than 100 million different photovoltaic chemicals to be measured. I also favor this method to find better thermoelectrics.
combinatorial photovoltaic particles on a gel matrix that changes color based on the amount of voltage and current produced to test 9 million new chemicals each pass.

So, we're testing random combinations of sixteen elements, to see which produce most power - but, instead of numbers, we're using visual inspection to highlight - literally - the best ones? |
|
| |
I think [Ian Tindale] might have some good input to this idea. |
|
| |
This idea sounds very familiar. |
|
| |
Is that "mass creening" (?) or "mas screening" ? |
|
| |
"Creening" does not seem to be a valid word in English (or even american). |
|
| |
"Screening" is a real word, but what's "mas" ? |
|
| |
We ask merely for information... |

Parthenogenesis of lottery tickets is not a well-documented phenomenon. The issue of sexual vs. asexual reproduction remains unresolved. Therefore, we assert that you (or someone) are in all probability communicating verbally via your Lower Rear Orifice. However, we are open to persuasion by additional objective evidence. |

So, my best guess is that more butt screenings are called for
by the idea, which seems wise given the state of the
average Western colon. Or it could be screenings of larger
butts, which seems unwise. |

so, 12 hours later, back to the technology? Maybe this could work with OLED molecules as well to find the brightest spiffiest ones. I used to wonder if OLEDs made with isotopically pure elements would have higher precision emitting spectra |
|
| |
//back to the technology?// Nah, it's bollocks mate. |
|
| |
From the title I thought this was going to be an
electrophoretic method. That would actually be a
good way to do it, possibly, I think, as opposed to this
electroscopic method. |
|
| |
Speaking of this electroscopic method, does
voltage/current really control pH in that way? Also,
wouldn't the gel short out the photovoltaic or
thermoelectric particles? |
|
| |
I have an electroscopy idea I want to post once I
work out its workings, which would do a similar thing
for a different purpose, but I wasn't planning to use
pH as a proxy for voltage. If your pH-proxy method
does work, I'll have to consider switching to that. |

Why don't you still wonder that? |

I found some images online of pH indicators like thymol blue changing color with voltage (1.2v) at the [link] so, a gel, full of thymol blue, with little electrically active photovoltaic dust sized particles could make colors visible to a scanning camera |
|
| |
well, I wonder a little about the isotopically pure OLEDs It is public domain now! |
|
| |
Interesting. Thanks for the link. I think what they're
doing there is electrolyzing saltwater and the pH
indicator is indicating the pH as the Na+ and Cl-
separate. That sounds like it takes considerable
current (i.e. more than microamps) to cause a
detectable change. I think for your application, and
probably for mine too, we need higher input
impedance in the voltage detection method. |
|
| |
I will try to flesh out my idea and post it as soon as I
can. You are welcome to use it for this application if
it's suitable. |
