01:18 < muurkha> nice
01:23 < muurkha> but it seems like they're using rather high voltages of 2.5, 3.0, and 3.5 volts
01:23 < muurkha> isn't that going to consume their copper anode?

09:23 < docl> I'm not seeing a reason aerographite production can't be DIY-doable. temperatures are microwave kiln range.
09:25 < docl> the ZnO template synthesis and sintering are higher temp but not extreme
09:29 < docl> I'm also seeing videos of welders made from multiple microwave oven coils and capacitors. not necessarily implausible to use that to produce your own ZnO tetrapods
09:45 < hprmbridge> kanzure> https://github.com/OpenOrion/turbodesigner
09:50 < juri_> careful with your microwave kiln. you can easily die from using it wrong.
10:02 < docl> yeah very true
10:03 < docl> looks like zinc can be sourced at $3/lb for animal feed ($1/lb 35%)
10:05 < docl> and I have toulene. can probably make hydrogen by electrolysis.

10:45 < docl> > ZnO-Ts were synthesized using a combustion method similar to previous work [39]. Briefly, commercial Zn particles (VWR CHEMICALS 29063.296, powder diameter ca. 5.5 μm, >97 %) were introduced into the combustion chamber. Air-entrained Zn particles were combusted on methane (99.995 %, Linde gas) flame, resulting in the formation of ZnO-Ts mixture of various sizes. ZnO-Ts powder was collected on the 
10:45 < docl> cellulose filter (Millipore, 0.4 μm) using a vacuum line
10:45 < docl> https://www.researchgate.net/profile/Mindaugas_Ilickas/publication/372747788_Highly-hydrophobic_transparent_and_durable_coatings_based_on_ZnO_tetrapods_with_diamond-like_carbon_nanocomposite/links/64f034410f7ab20a86674339/Highly-hydrophobic-transparent-and-durable-coatings-based-on-ZnO-tetrapods-with-diamond-like-carbon-nanocomposite.pdf
10:46 < docl> bulk ZnO tetrapods is probably a major bottleneck overall, but looks like a reasonably optimal solution has been found with flame synthesis
10:48 < docl> in that paper they describe dissolving the product of flame synthesis in ethanol and centrifugally separating different kinds of tetrapod
10:52 < docl> that sounds unscalable as they use 50 mg/ml dillution. I'm imagining an airjet process where the difference in arm length dictates how far a given tetrapod travels. might require low pressure. so long pipe, pinhole inlet, rough vacuum pump
10:55 < docl> maaybe solar photonic separation from an air-dust mixture. or a static cling differential based mechanism. I'm assuming we want a specific particle for the AG sacrificial template

12:07 < muurkha> Ts?
12:19 < docl> plural of T for tetrapod
12:43 < muurkha> aha
12:47 < docl> the temp needed to make ZnO is 900-1200 C so I can use borosilicate. my butane torch barely softens borosilicate, should be hot enough. I might need an O2/Ar mixture to get it to cook right though
12:48 < docl> some synthesis techniques here: https://journals.sagepub.com/doi/pdf/10.5772/60939 // ZnO Tetrapods: Synthesis and Applications in Solar Cells

15:14 < docl> muurkha: you were right, aerographite is glassy carbon (depending on the form). the lightest form is ribbons in a transition state between amorphous (high sp2) and vitreous (completely sp2)
15:21 < docl> looking at the electron micrographs it has a lot of empty space. not sure a 1um thick layer isn't transparent

17:52 < Ashstar> nsh, Suprachiasmatic nucleus, takes signals off our optic tracl
17:52 < Ashstar> SCN
17:52 < Ashstar> tract
17:54 < Ashstar> that is why our exposure to certain amount of lumens per day for a certain time period
17:54 < Ashstar> also why, those without it have isues with their circadian rythm
17:54 < Ashstar> issues
17:55 < Ashstar> also why people experience SAD
17:55 < Ashstar> Seasonal Affective Disorder
18:33 < Ashstar> I guess, I was responding to your statement: <nsh> .gpt4 what are gate cells in the context of network zeitgeiber theories of circadian rhythms especially within the SCN?
18:33 < Ashstar> <gptpaste> ​The term "gate cells" is not a standard term widely recognized in the context of circadian rhythms or the suprachiasmatic nucleus (SCN), which is often referred to as the master clock of mammalian timekeeping. However, based on your question, it seems you are referring to a concept related to how signals might be gated or modulated within the SCN or other parts of the brain 
18:33 < Ashstar> - 
18:35 < Ashstar> I started out at NIMH doing circadian studies with Macaque mulata CSF bioamine turnover
18:36 < Ashstar> at grad school we worked withNeurospora crassa
18:37 < Ashstar> Neurospora circadian system includes a genuine clock in which a molecular negative feedback loop based on transcription and translation runs its course over about a day
18:39 < Ashstar> https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3203324/
18:40 < Ashstar> yes, gated channels are involved

22:40 < hprmbridge> nmz787> Is SAD cured by just being outside?
22:41 < hprmbridge> nmz787> How many minutes or hours of overcast winter light is needed?
22:58 < hprmbridge> gourneau> https://github.com/cumulo-autumn/StreamDiffusion "StreamDiffusion: A Pipeline-Level Solution for Real-Time Interactive Generation"
23:04 < Ashstar> the amount of light needed is above 50,000 lumens for several hours each day
23:04 < Ashstar> full spetra
23:04 < Ashstar> spectra
23:05 < Ashstar> so it seems
23:11 < Ashstar> that seems to synchronize our SCN
