my favourite kind of high to get is the kind where i become obsessed with understanding a scientific concept that has eluded me until now. today i finally wrapped my head around paramagnetism and diamagnetism

no youre right. im a professional Color Autistic and the color wheel they give you in primary school is A FUCKING LIE ITS A FUCKING LIE. RED YELLOW AND BLUE ARE NOT THE PRIMARY COLORS. OK.

So basically the only real primary colors are red green and blue. Those are the only scientifically valid primary colors. In printing, everyone has just DECIDED that cyan magenta yellow and black are good colors to put in printers for maximum efficiency. And PAINT. When they give you red yellow and blue they're talking about paint. BUT THE THING IS. ITS A FUCKING LIE.

There are no primary colors in paint. There are a BAJILLION pure pigments (phthalocyanine ! quinacradone! cadmium! titanium! lapis lazuli! amethyst! Gold! Lead! Iron oxide! Cow shit! Mummies !!!!! Arsenic !!!!!) and it ENTIRELY DEPENDS on what color you want to make which colors you use for it.

Using a green-tinted blue and a orange tinted red will make a shit awful purple.

Anyways. All this being said.

Magenta is actually the opposite of green.

A greener route to blue: New method drastically reduces amount of solvent needed to produce organic dyes

Phthalocyanines are used in renewable energy production, sensing, nanomedicine and more. Researchers at Aalto University have demonstrated how the dye can be produced in a greener way that minimizes high-boiling organic solvents, by using solid-state synthesis instead.

Organic (carbon-containing) dyes have important roles in nature. For example, they are responsible for transporting oxygen and other gases in the body (as part of hemoglobin) and converting solar energy into chemical energy in photosynthesis (chlorophyll).

One class of artificial organic dyes is phthalocyanines, which are widely applied in industrial processes, sensing, nanomedicine, solar cells and other optoelectronics. However, the production of phthalocyanines is not without its issues, says Eduardo Anaya, Aalto University Academy Research Fellow and one of the main authors of the new study.

"Phthalocyanines are produced by using a lot of solvents such as dimethylaminoethanol (DMAE). It is corrosive, flammable, bioactive and harmful to the environment."

So I saw this on my dash and I had to dig a few articles deep to actually get an explanation of what’s going on.** Solar energy generation, storage, and conversion is something I’ve been studying since about 2015 as a researcher, so I’m always really curious what’s actually new about these articles.

Since even before my time, our field has been pretty adamant that the most important problem we face to a green energy future is how do we store our green energy. We can make tons of it! In fact, TOO MUCH for us to use. We just have no way of storing and delivering it once we’ve made it. People have been working on batteries (solid-state, redox flow...), chemical energy storage (use sunlight to make a chemical reaction that produces a fuel like hydrogen gas, petroleum, methane...), and many other ways to store solar energy for decades and decades.

Besides the fact this is just like, what I do for a job and enjoy thinking about it, figuring out what actual tech is being lauded as Good News was important to me. I (and you) need to know whether this is revolutionary phenomenal more hope for the future kind of good news, or if it was oh hey, this thing we’ve been working on for 20-30 years is finally reaching an almost-market-ready stage (and TLDR: it’s the latter).

So what makes this one newsworthy?

The device developed at Chalmers* is a form of chemical energy storage. Instead of making a fuel to use and burn, the chemical they shine light on purely stores energy, and releases energy. They have recently managed to package it into a neat little chip that takes sunlight, stores it, and then on-demand returns it as electricity that we can use.

-:-

The chemical they’ve used on this chip can exist in two differently shaped forms. And it can change between those forms with a little bit of energy. The researchers determined that the energy requirements for that transformation is small enough that sunlight can perform it.

So they shine light on one form of the molecule and it turns into the other; it takes the solar energy and “stores” it by resting in that new shape. It’s happy to sit there until they tell it to go back.

When it goes back, it “returns” the initial energy by giving away heat.

They’ve been able to turn heat into electricity somewhat efficiently.

The limitations of this kind of device are:

How much energy you can store is dependent on how many molecules you have on your chip (or in your tub, if you’re doing it in liquid form).

How efficiently you can turn that heat into electricity is a developing technology and they have room to go.

This specific set up requires an *additional chemical*, a catalyst (unsung heroes in most of the press) to help turn the transformed molecule BACK into its original form, the important step to deliver energy back to us! Cobalt(II) phthalocyanine is a known catalyst for these kinds of things and has its own drawbacks.

Doing this in liquid form currently requires organic solvents (in everything in life, we want to use water instead of organic solvents, if possible).

What % of the sun’s light is actually DOING this transformation limits how many of your molecules are actually going to change their shape.While yes, these chemicals do perform this transformation under solar light, specifically they require UV-light. There’s not *actually* a lot of UV light *in* sunlight; ideally, you’d want something that works in visible light (about 40% of sunlight is visible; about 5% is UV). (This is also a major limitation of many other solar technologies.)

Why am I explaining all of this?

I think it’s important for non scientists, particularly those who care about the climate crisis, to have this context. This technology is not a one-off moonshot; this technology is not our best hope; this technology is not the Answer to all our problems; this technology is not unique. The concept itself is also not new. It is not even “in its early stages” as far as research goes. This is a fairly well-developed device and system they are publicizing. It IS in its early stages of implementation.

This is the pace of science. And that should actually give you hope.

It means that for every one individual piece of news you hear like this, there are hundreds of different technologies also being developed, also being worked on, also close to implementation, too. People have been working on these problems, caring about these problems, UNDERSTANDING these problems, for decades even before the public ever caught up. There is progress being made and hope to be had, and nihilism about the climate, about whether The Big Feds and Corporations Are Paying Attention, is both inaccurate and counterproductive.

It IS exciting that this one is working to the degree it is. It IS going to be a useful tool in adapting to our energy needs and making a green future possible. And to me, as someone who’s been watching this field, it’s really exciting and satisfying to know that hey, all this hard work we’ve done uncovering the different pieces of this puzzle..? we’re starting to actually PUT THE PIECES TOGETHER in a functioning way now.

Sometimes even as a scientist, even as someone who understands the pace of research, it can be hard to feel like there’s ever going to be the point where things start working. We’ve been pursuing photoisomerization as energy storage for ages and ages, but it’s never been efficient enough, or we’ve never had a way to release the energy once it’s been stored, or all these other problems. But we’re finally at a point where grit, determination, persistence, and hope, have gotten us through the worst of those issues and gotten some solid footing. And that’s really exciting

-:-:-

*(woo, Gothenberg, they are a hub of green energy development and a bunch of my friends work there. some of them have even worked on related projects as visiting researchers over the years)

**You know what’s really personally annoying about this blurb on tumblr and the euronews article itself??? I had no clue from either of them that I HAVE ACTUALLY REPORTED ON THIS, PROFESSIONALLY. They didn’t link back to a Chalmers press release, or to the researcher’s group websites, or to the papers, in an obvious or accessible way. One of the scripts I worked on last month was literally about this paper and I had to help one of our writers explain what photoisomerization is and thermal electricity generation. It took way too much digging to realize that.

I should have been able to understand from reading this blurb and especially from reading the press release what this actual development WAS.

Good popular-science / general public articles should convey to both non scientists and scientists what the actual technology/research finding is, from the get-go. Anyway, that’s a pet peeve of mine with science communication and with these “hopey fluffy happy science” blogfeeds. You can do better, without descending into the nitty gritty like I did in this longform tumblr post. (And we did, for our show.)

Smaugust 2023 day 6. Amphiptere dragons with clouds and spirals.

8/7/2023. Dip pen and paintbrush with Liquitex Ink "Phthalocyanine Blue (Green Shade)". Some clean-up with white-out pen. Minimal digital clean-up in Krita.

Used triangle measuring tool and ruler, while drawing, in attempt to keep composition edges straight. I didn't want to draw a pencil line to erase later, because the erasing process might give too many opportunities for ruining it.

man phthalocyanines are great, super easy to tell at a glance if my synthesis succeeded or not based on whether it lets zero light into the vial lol

[lycomorpha]

Gave myself a minute to try making some new paint this Sunday 💚🖌️ This is phthalocyanine green (yellow shade) aka PG36. It's a very deep, staining, emerald green. Like phthalo blues, it's a little reluctant to mix with the binder at first, but smooths out ok. It's not a colour I use on its own much, but it's an important component of my most-used paint colour; sap green.

It's the first time I've used it, so I started with 5g pigment and measured how much binder I needed as I went. I swatched the paint a couple of times while mulling it, to help decide if I needed more binder. We'll see how it dries and then find out if I judged it correctly! 😅

I am somewhat obsessed with greens. Although I'm most interested in earth pigments, I'm also curious to try making modern synthetic versions of historic colours that aren't practical and/or ethical to make nowadays. Sap green colour used to be made from buckthorn berries, and formed a thick liquid that didn't dry to form a paint like watercolour - it was carried/kept in pigs bladders apparently. So uhh... I'm good with trying a modern homage to sap green rather than reaching for the buckthorn and bladders, yknow?

New Profile Picture! I painted it myself! :D

Watercolours Used: Phthalocyanine Blue, Neutral Tint, and Hansa Yellow Deep (All M.Graham Paints)

Notes: I took a lot more time focusing on lighting, and I really like how it turned out! I also used a lot of references for the hood and folds. What I will improve on in the future is neatness----there was some blue that ended up on the beak. I will get together brushes to sacrifice to my jar of masking fluid haha!

✻ I go by Wynn here, but I have no objection to nicknames as long as they are not offensive or harmful. Have fun with it!

✼ When it comes to games, my biggest major hyperfixation is genshin impact. It's definitely something I invest a lot of my time in, not just in gaming but also in my writing and drawing. (Update: Baldur's Gate 3 has also consumed my entire soul now). I have played some Honkai: Star Rail and absolutely loved the first parts to it, but unfortunately had to hold off on playing any more for lack of computer space. Once I can get my hands on a proper gaming PC, I would love to play Undertale/Deltarune. I am also one of those people who could sit you down and give you a several hour rundown of the FNAF lore. Depending what consoles I'm able to get in the future, I'd also love to get into playing the Zelda games.

✻ Jujutsu Kaisen makes me want to throw my laptop out a window right now. There's your intro the the kinds of shows I like. I am a weeb and I really like (but also deeply hate) Jujutsu Kaisen, Bungou Stray Dogs, Demon Slayer, Attack on Titan, etc. If it makes me suffer emotionally, I probably enjoy it. I am also attempting, key word being ATTEMPTING, to get through One Piece. Gotta catch up with my frinds who are actively up to date on it please pray for my soul. Also getting back into Fairy Tail and loving every second of it! If it's not anime, I like a lot of the MCU shows or movies, and also have yearly rewatches of Gravity Falls and the new comfort show addition of the Owl House to give myself a break from the emotional torture that comes from being a weeb. I watch Helluva Boss and Hazbin Hotel religiously, my sense of humor is broken.

✼ I like reading. Unfortunately I stopped being able to stay motivated to read regular books sometime back in high school. What has my solution to that been? Webcomics! I have a much easier time keeping up with reading if stories are paired with pictures, so Webtoon is my biggest go to for that. My biggest recommendations for those who also enjoy webcomics would be Omniscient Reader (my current top favorite if you don't mind lots of cliff hangers), City of Blank, Lore Olympus, Down to Earth, and Covenant.

✻ !!! If you have any recommendations ever for games, shows, movies, webcomics, songs, or any other sort of media, feel free to send them my way! I love checking out new genres and subjects and learning about the sorts of things that other people take interest in and that's usually where most of my interests come from any way. I am an interest sponge!!!

✼ Most of my time is spent writing, drawing, or playing genshin. I also enjoy baking, painting, making carvings out of bars of soap, and driving my entire family crazy by being hyperactive at the ungodly hours of the morning. Since I at least do my best to get out of the house sometimes, I also enjoy hiking, any sort of rafting or boating, and scuba diving. I have a lot of travel goals since I enjoy seeing new places and exploring. I have also recently finally achieved my middle school dream of finding a group to play DnD with, and it has become a major hyperfixation. When I can't think of things to draw? DnD character. Not sure what to write but needing to put some words on paper? DnD character backstory. Bored or unmotivated in general? Make up new DnD characters. It is my cure all.

✻ My top three favorite animals go sloths, possums, bats in that order from favorite down.

✼ My favorite color is very specifically phthalocyanine green

✻ I love anything related to outer space and could probably talk for hours about it

✼ Same goes for the ocean. I think I just find all the unknowns about both the ocean and space to be very cool

✻ I like sushi. A lot. It's a major comfort food and if it wouldn't make me sick I could probably have sushi every day and be perfectly satisfied

✼ I enjoy anything that has me working in the kitchen, and I'm actually hoping to go to culinary school sometime in the next few years

✻ I try to hoard DnD dice like a dragon hoards treasure which is probably why I can't afford a better gaming setup :,)

✼ Making art for people is my love language I could probably make money off of it but I don't because making free art for people brings me joy and joy > profit
