Chemical computers/Chemical electronic devices
Hello, Exotic devices have since long been a passion of mine for ages, in fact I'm not sure if I should post this to technochemistry or here, for
instance... it will get clearer as I expand my insane reasoning or lack thereof.
Hello again My fellow molecular manipulators, I heard of chemical computers for a long time, but everytime I make up some time to savor my curiosity
all I find are vage white papers and some russian stuff. I tried looking for electronic(electrochemical devices) but little to no avail, all I found
was small pieces here and there about dimmer made with water salt and a graphite rod, I also found something about a rectifier made iwth aluminium(https://simplifier.neocities.org/rectifier) anode. I hope all can see what I'm getting at here... I do love electronics and exotic electronics, I
do have some vacuum tubes to do experiments with, yes in this day and age... but I'd like to step up my game in the uncommon, for the sake of fun. so
I ask, have any of you seen anything like it? any resources of chemical computers and the integration of chemistry, in special
electrochemistry(inorganic/ionic stuff) devices, I don't know, transistors, switches, diodes anything at the intersection between electricity,
electronics, chemistry and electrochemistry. variable resistors, memrirstors(I've seen some here :http://sparkbangbuzz.com/memristor/memristor.htm )
I want sugestions, tips and if possible learn new tricks. stuff that ios practical in a home lab environment. I hope I managed to convey what I want
in an understandable manner, though if not, please ask questions and I'll try my best to clarify it.

Most electronic devices rely on physics rather than chemistry,
the only chemical devices that I use for electronics are
A Weston standard cell for a voltage reference
and batteries.
Halogen lamps rely on chemistry (and of course physics)
Chemical etching of pcb copper sort of qualifies
Some equipment has a device to indicate total time powered up, based on electrolysis

that is very true, that is why I'm looking for it, because it is interesting, unique, that time indicator, is a fine example of what I'm looking for.
I mean, the concept of electroplating/electrofoming would allow for dynamically changing circuits, it is just a concept I got a few years ago, but
never matured enough for me to have something to try. I may be considering something impossible or impractical, but... what I'm after here is fun, and
stuff like this appeals a lot to me. but anyway, thanks for your reply and the valuable info on that pdf does confirm to some extent that I'm not
that insane, though what I've imagined is yet to be seen. still a step at the time.

Moving ions around is inherently much slower than moving electrons around,
so electrochemical systems seem to me to be suitable for detecting/measuring/monitoring slowly changing variables,
and/or controlling slowly operating devices
(eg indicators, displays and maybe electromechanical devices)
PS just a thought, that may help you to avoid rabbit holes;
with solid state devices, speed is usually limited by
dV/dt = I/C
so to go fast you need:
large currents - which cause heating/power loss
small capacitance - which limits size hence current carrying capabilities
small dV - which requires low voltage operation
You can equally consider speed being limited by
I(avg) = F.dQ and dQ = dV.C

Once a crystal lattice is constructed, chemistry, for the most part, doesn't play a role anymore in the function of electronics. It does however
explain most component failure that is do to excessive heat or current. Oxide layers rearrange themselves, changing the desired structure, liquid
filled capacitors undergo decomposition reactions. Tin likes to reform and grow fine hairs that shortout connections. There are even gasses that
penetrate the protective plastic and change the propertys of semiconductors.
Years ago we build a plc system that was quite nice, very profitable. But was to be used in a hazardous environment, for extra protection, we used
argon to fill the compartment containing the high voltage contacts. After a few minutes of testing, each and every relay was welded closed. Very bad
day. Damaged a lot of equipment. The culprit was "cold welding". After the contacts were worked, the normal arcs removed the oxide layers, providing a
perfectly clean surface, and presto, the 2 contacts became 1 solid peace of metal

Sensing would be the biggest crossover of chemistry and electronics I can think of. eg pH and ORP probes, and the various gas detectors available (CO,
CO2, O2, H2S, SO2, VOCs etc ). So maybe you could try to create a computation based around generation and sensing of chemical compounds in some kind
of mad chemistry/electronics mash-up.

Few years ago I participated in a startup which is making a new kind of CPU based on mixed chemical/physics effects. In reality it is 99% chemistry
but some physics also. I unable to say what is the technology is (NDA) but I am able to say that this field is very wide for anybody who wants to
explore it. The most challenging is to go from theory to working device and it costs investor's money.
I don't know wether they posted new info besides this: https://www.intelnn.com/
As for me the most challenging problem of any chemical processor could be the number of operation it can perform before the structure can degrade and
I think the most battle would be around this.

Interesting... but apologies, I would like to say my calculus is a bit rusty, however, I am ashamed to admit that my calculus is inexistent. I knew
that skipping a lot of math would come back to bite my behind, and here I am, thanks for the tip though.

As Rainwater said, hes, sadly most electronics rely on chemistry up to production phase only, instead operation. And when cbemistry is involved in the
operation it has more to do with support and maintenance. Still, can give me some ideas to try....

True, and it will be even more relevant in the future with computers doing basically everything

Now this is close to the meat and potatoes of the frankenstein monster I am looking for... I wanted to find something that is "non-solid-state"
electronics, it didn't needed to be chemical (bonus if it is) hence why I did researched even vacuum tubes... I don't know, alternatives to solid
state, a "liquid-state" electronics if that is or even can be a thing. Very interesting, reminds me of my time about 5 years ago obsessing over
artificial neurons and came across an electrochemical model cor that, all theoretical, haven't seen such contraption. However I spent weeks just
imagining all the implications of degradation, like batteries over time, electrode corrosion, malformations on the recharge state, solution and
everything alike... kinda like and artificial organism without capabilities for self renovation and correction. Still... sometimes I catch myself day
dreaming of the possibilities.
Thanks for all replies, each and everyone of you brough something for me to think about. And if there is more, please, post it here.

The "integration of chemistry and electronic devices" (from your original post) is exemplified by batteries and integrated circuits. The subject of
'batteries' is so broad it will keep you occupied for a lifetime. If you expand it to include "energy production and storage" it will keep you busy
for 10 lifetimes.
The pioneers in developing modern IC's were chemical engineers; practically the entire IC manufacturing process is chemistry on steroids Why don't you
make your own, simple, integrated circuit? There is lots of chemistry involved....

If you haven't run across the Journal of Unconventional Computing or Adam Adamatzky, you might like their stuff. Some of it, like the voronoi
"computer" from supersaturated sodium acetate, stretches the meaning of "computation" (one of the philosophical articles is titled, "If a tree casts a
shadow, is it telling time?"). A lot of it is also theoretical or model-based, but I've picked out some things that have material, meat-space results.
A lot of it involves reaction-diffusion systems like the BZ reaction.

Basically, if I would make the research, I would try to build simple oscilators based on all known chemical or chemical/physical effects. Then I would
try to increase the life of them and finally I would concentrate of technologies where there is a success of keeping the non-stopping oscilation
longest time.

Believe me, how I wish that, though, many of the materials, waffers and stuff are not just inaccessible but those that are, are rather expensive to
me, so a silicon cooking kit is a far cry from what I am able to manage living in the middle of nowhere(as per se) and having a monthly budget so
small that it might as well be inexistent. Though I do have on my list an idea to get my hands on a microwave transformer and modify it to output lots
of current to turn sand into silicon carbide to see if I can make LEDs, and also use of zinc sulfide or copper oxide I to make photocells, if I had a
cheaper and more accessible alternative to silicon for that, it could be interesting l, too bad most of it is not as stable as silicon, not that
making an IC and microscopic lithography is at my grasp, but starting with my own transistors would be nice

"....and having a monthly budget so small that it might as well be inexistent"
Okaaay... then why don't you use what's around you.
Brainstorming chemical-electrical ideas:
1. Invent an organic solar panel: Embed chlorophyll on a suitable substrate, capture the current generated by it, store it in a battery.
2. Speed up carbon capture: Increase the output of ATP synthase by optimizing the H+ gradient in mitochondria.
3. Make inexpensive grid power storage: Take one of the many microbe battery ideas out there, and scale it up.
Any of these would make you wealthy, qualify you for the nobel prize (and fast), and win the neverending praise and respect of your peers, and they
all use readily available materials

I see, well, that is something I can get behind. My deepest thanks Johanson, your sugestions were very helpful, not only in opening my eyes, but in
giving me a sense of direction to help me in getting out of limbo, since I've been lost for a few months now wanting to do something, but not knowing
what. And indeed everyone here pitched in. I am grateful to all you guys. Expect something new to pop up on Technochemistry, I will do my best to make
it interesting.

There is plenty of ways how to build computer logic on top of a chemical reaction but to really beat the modern silicon technology we need to find a
way to build a skeleton from molecules which will hold those molecules which performs the computation operations. In living cells the cell skeleton is
also the essential part. So, we have 3 questions: how to build the molecular skeleton, how to attach or grow the required molecules in the designated
parts of it, how to make the connections.
A lot of current researches are based on a "mechanical" way of "crystal" composition - 3D printing or similar. But those are already in pre-demo
stage. So, as a scientific research the next step - the structures based on a molecular skeleton - is probably will pay the efforts.

So there is a name for this? I read the review on the bus going to work this week, and I must tell, I am surprised, I mean, I am not arrogant enough
to think I was the only one to think of it, but to think that Westinghouse, Raytheon, American Air force and Navy were involved in this, do tell
volumes. Though their approach was different from what I imagined, their goal and what has been made is very close to what I imagine. Thanks for
posting this, It has been a long time since I last had such pleasant reading.

khlor, it was your initial question as well as my small participation in molecular optoelectronics before which motivated me to continue studying of
the field.
As you read in the review, there were different type of scientists involved. The review names 2-3 very good scientists and I would say their work are
very interesting even if they don't have name "molecular electronic" on it. I would recommend to read everything written by Jean-Marie Lehn and Fritz
Vogtle. They are also editors of several books.
There are also 2 books with recent reviews of everything which is related to molecular electronics:
- Supramolecular Chemistry (Steed, Atwood, 3rd edition 2022).
- Organic and molecular electronics, from principles to practice (M.C. Petty, 1st edition 2019)
The molecular electronic, I think, consists of three part: how to make basic elements (wire, transistor, logic, memory), how to assemble a device from
elements and how thermodinamic and chaotic processes are involved.
The modern tendency is to operate a single molecule under the microscope, it is interesting but not suitable to production.
So, I think as a subject of study is very important the second part: how to assembly molecules to devices on a big scale.
I have opinion that any advance in the field will be achived with improving of computational methods and molecular self-assembly modelling software.
P.S. What is surprising, that the main ("iconic") figure who was driven the "molecular electronics" through 1970-1980, Forrest Carter doesn't have a
dedicated article in wikipedia yet.
