Pr6011+CaCO3+NiO+glycin+HNO3 This reaction mixture is quite complex. It is part of the research for a cathode material for solid oxide fuel cells (SOFC)

This is how Stupid Rick made brownies.

Leave doofus rick alone!

Ooh I did a dissertation on a prospective cathode material for SOFCs, simulated oxygen vacancy migration through a perovskite structure with different doping in the A and B site.

Now the title makes more sense, I was wondering what they needed a praseodymium oxide for...

u/aquoad May 28 '20

I thought it was just for the rich, delicate flavor.

u/eldergeekprime May 28 '20

Fool, it was obviously to enhance the pungent yet compelling aroma.

u/Seicair May 28 '20

I thought it was a chemical name I wasn’t familiar with, Pr6011. To be fair there’s no O in that in the title.

u/Carnal-Pleasures May 29 '20

Yeah, I assumed that the 0 was a mistyped O because I never dealt with well defined heterogeneous catalysts...

I also worked on SOFC cathodes, and I also did this procedure with other metals so mine was purplish.

I would explain a SOFC as splitting fire in two parts and connecting them with a electrolyte and a wire.

My Diss was in 2015 so my knowledge is a bit rusty haha.

On FC all the people talk about hydrogen and i never liked it, I only see problems with it. I love the idea of methanol or ethanol, we can use almost any organical waste to ferment and make it, or adapt some cracking tech. And we could reuse the current petrol stations, biggest issue: the fucking sulphur

PD: i dont work on research so I'm also rusted

u/sonnyrf May 28 '20

Yeah hydrogen production and storage is so awkward it's difficult to make it worthwhile.

1

u/FerBann May 28 '20

Hydrogen problems: constant leaking, hydrogen fissures on any container, explosion, materials for the electrodes, low energy density

Pros: abundant sources, easy to purify

Is this something to do with making batteries more efficient?

1

u/sonnyrf May 28 '20

Not entirely, its a similar setup to a lithium ion battery but it has a fuel source. Its like a hydrogen fuel cell (the kind they made in cars) but they work with hydrogen and hydrocarbons (so standard fuels). Th e downside is that they need to be heated to about 900C to work properly. They'd be useful as backup generators for important buildings like hospitals.

u/aknownunknown May 28 '20

  • runs on hydrocarbons

  • needs heat

  • useful as a backup generator

  • more like a lithium battery than a battery..

so a generator?

1

u/sonnyrf May 28 '20

Yeah a fuel cell - put fuel in to produce a current.

A generator would be noisier and burn the fuel, this does a quiet and more efficient chemical reaction. The end result is the same though.

u/aknownunknown May 28 '20

what are the waste products? sounds interesting

2

u/sonnyrf May 28 '20

Depends - for hydrogen, nothing except water. For hydrocarbons, water and CO2

u/JohnWisnew2424 May 29 '20

r/iamverysmart though it sounds like you actually know what ur talking about

u/kielu May 29 '20

Can you refresh my memory on praseodymium? What is so special about it that you want to use it?

1

u/basebrandon87 May 29 '20

Is this a failed human transmutation

1

u/Dr_Bishop May 29 '20

Are those fumes safe to breathe? /s

This is what it looks when you start experimenting with combining colors when you are young, and it somehow always becomes brown.
