I'm an H⁺ denier, in that I refuse to consider loose protons to be real hydrogen, so I personally believe it stands for 'pretend'.

Chemists discover common plastic pigment promotes depolymerization

It turns out that the black plastic lid atop your coffee cup has a superpower. And the Stache Lab at Princeton Chemistry, which uncovered it, is exploiting that property to recycle at least two major types of plastic. Their startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process called photothermal conversion, intense light is focused on plastic containing the pigment that jumpstarts the degradation. So far, researchers have shown that carbon black can depolymerize polystyrene and polyvinyl chloride (PVC), two of the least recycled plastics in the planet's waste stream. Through a process called photothermal conversion, intense light is focused on plastic containing the pigment that jumpstarts the degradation.

A staggering 60 million tons of polyester are produced annually, for things like clothes, couches, and curtains. That polyester production takes a toll on the climate and  environment, as only 15% of it gets recycled. The rest ends up in landfills or incinerated, which results in more carbon emissions. “The textile industry urgently requires a better solution to handle blended fabrics like polyester/cotton. Currently, there are very few practical methods capable of recycling both cotton and plastic—it’s typically an either-or scenario,” explains postdoctoral researcher Yang Yang of the Jiwoong Lee group at the University of Copenhagen’s chemistry department. “However, with our newly discovered technique, we can depolymerize polyester into its monomers while simultaneously recovering cotton on a scale of hundreds of grams, using an incredibly straightforward and environmentally friendly approach. This traceless catalytic methodology could be the game-changer.”

Fwiw that guy is right about avoiding depolymerization and was probably only saying true shit people just hate it when you're correct.

Read Plastic Man No More, story about Eel going through what all plastic eventually does and depolymerize

it was ok

good art, touching moments for the character, but they wrote most of the league in a very cold, corporate manner

it also ended with plastic man becoming plastic hand which is really funny

Pseudomonas aeruginosa

Polyethylene plastic, found in products such as plastic bags, water bottles, and food packaging, takes 1,000 years to dissolve naturally.

The RPI team tackled the challenge of engineering this bacteria to convert the carbon atoms of polyethylene into a genetically encoded silk protein.

Polyethylene is particularly problematic, as it is commonly found in single-use applications. Resultingly, polyethylene is the most commonly produced plastic, representing 30% of all plastics production

Mechanical recycling is inefficient, typically yielding materials that have inferior mechanical properties compared to virgin plastics.

The development of a new strain of Pseudomonas bacteria capable of converting depolymerized polyethylene into high value bespoke recombinant protein products.

Happy STS! So, while recently thinking about the words depolymerize, neodymium, ammonium persulfate, and other chemistry-related terminology for no reason, I found myself wondering: How do you go about your chemistry-related research for GSNBTR, and how do you decide which compounds, etc. to name-drop for the scientific elements of your story?

Happy STS, Kate!

Hmmm ... what a funny question to ask, being that I'm an English and creative writing major with absolutely no knowledge of any of those concepts. 😅

The truth is, a layperson can sound fairly authoritative (at least to other laypeople) using a combination of knowledge gleaned from AP science courses, years of having read widely but not particularly deeply, and, of course, Google. 😅

It really does help if you do have some baseline knowledge, although you don't need much. For instance, I'd heard of the concept of neodymium magnets, although not what they were actually called, so I googled "strong magnets used in scientific research" and they came up instantly.

Same thing with depolymerization, basically. And then as I was reading about that, it emphasized the importance of catalysts, of which ammonium persulfate is a common one -- essentially chosen at random, though I tried to go for something plausible. Reading about that, in turn, led me to the process of electrolysis, which is the common way it's synthesized in the lab. In that way, one concept can lead you to another.

The key, for me, is to go lightly on trying to explain concepts I myself don't fully understand, or I'll end up sounding ridiculous. If you're fairly sure you understand something, chances are your readers will, too. And have faith that your scientific wunderkind of an MC can handle everything else 😁

And of course, all of this is predicated on the assumption that nobody reading my work is an actual research chemist, because if they are, they're sure to hunt me down and hurl a beaker of sulfuric acid in my face (yes, I googled that, too). 😂

(For anyone confused by this delightfully tongue-and-cheek answer and question, the words Kate mentioned all appear in Ch. 31 of GSNBTR, posted yesterday. )

Society/Culture

Most 'sex education' past the basics relies on linux user logic (it doesn't work in practice)

So I was at a furry convention a couple months ago and I was at a panel where a guy was explaining how he fit insanely huge dildos up his ass. To be fair, the guy was a bit drunk explaining it but the panel just didn't convince me. He tried to convince the audience how asshole stretching is a myth, how the inside of the anus will over time reshape itself to accommodate extremely large dragon dildos, how you absolutely need to use certain kinds of lubricants or the dildo will be entirely ruined by depolymerization, how you need to be constantly paying attention to what you're doing or you fuck things up (like how his surgeon once shaped the inside of his ass back to normal, which fucked up years of training his anus to accommodate the dildos) etc etc etc … It really struck me how much of it seemed exactly like the kinds of rationalizations a linux user might come up with. You need to constantly be doing everything perfectly and any fuck up is because you weren't informed enough, therefore it's entirely your fault. There's also the exact same extremely opinionated takes on every topic - literally when someone tries to convince me to use something like GNOME or Wayland on Linux, I think back to how hard that panelist was trying to push buying dildos from Etsy businesses instead of Bad Dragon. I think in any community that encourages black and white thinking, whatever information is provided will inevitably only help those who obsess over minutae while providing a bad experience for anyone else … which in my controversial opinion describes kink spaces pretty accurately.

An enzyme used in laundry detergent can recycle single-use plastics within 24 hours

Scientists at King's College London have developed an innovative solution for recycling single-use bioplastics commonly used in disposable items such as coffee cups and food containers. The novel method of chemical recycling, published in Cell Reports Physical Science, uses enzymes typically found in biological laundry detergents to "depolymerize"—or break down—landfill-bound bioplastics. Rapidly converting the items into soluble fragments within just 24 hours, the process achieves full degradation of the bioplastic polylactic acid (PLA). The approach is 84 times faster than the 12-week-long industrial composting process used for recycling bioplastic materials. This discovery offers a widespread recycling solution for single-use PLA plastics, as the team of chemists at King's found that in a further 24 hours at a temperature of 90°C, the bioplastics break down into their chemical building blocks. Once converted into monomers—single molecules—the materials can be turned into equally high-quality plastic for multiple reuse.

Anyone can speak authoritatively on if Carbios is the real deal and how it compares to competitors? Polyethylene terephthalate (PET) plastic degradation opening up in France

Should I be reading this paper out of IIT or is there a simpler direction to get a read on the industry?

Would be interested to see American based competitors to emerge. Especially if we can safely do it in the mid west and parts of the south. Would be a cool job
