Interesting video, this is far from resolving all the world's issues of course, this is essentially throwing a bunch of plastic in a tube and microwaving it to extreme temperatures, but it can create a ton of graphene (30mg plastic -> 5mg graphene conversion). The proposed use for this graphene is in cement mixes in order to toughen concrete and reduce wear on roads and structures. > The technique uses flash Joule heating (FJH) to heat carbonaceous materials to temperatures over 3000 K in ∼100 ms, producing >90% yields of high quality turbostratic FG (tFG). The high temperatures of FJH result in high purity tFG, since much of the non-carbon atoms are removed through sublimation Using this much energy is of course problematic, sure, it can get rid of the plastic, but we are largely burning fossil fuels to create this energy. It takes 400-600w of electricity to produce this much graphene, which is certainly a breakthrough for graphene production, at least, because of how labor cheap this is. Its also much cheaper electricity wise than pretty much every pre-existing recycling method, which is certainly a good thing. > In this study, the goal is to broaden the application of APMP to solid precursors, specifically converting microplastics into graphene. In contrast to the traditional method of initiating graphene production from gaseous-phase products, this approach involves the transformation of PE microplastics into gases such as methane, ethylene, and ethane, and then converting them into graphene within the plasma, all in one step. Furthermore, the advantages of microwave-based technologies in terms of energy consumption and cost compared to conventional techniques for recycling or upcycling polymers can be found in recently reported studies.[27-29] Following the successful synthesis of graphene, we also showcase its effectiveness in adsorbing perfluorooctanoic acid (PFOA), facilitated by ultrasonication. The beauty of this is you don't have deep concerns about offgassing, the plasma captures the most harmful vapors and flash converts them to a graphene powder, which resolves a concern of harmful contaminates to local areas of production. It will mostly offgas H2, Carbon monoxide, and Co2, though the paper doesnt seem to discuss the quantities of each gas it produces. Co2 offgassing is obviously problematic itself if that quantity is very high, you're essentially turning a lot of the 'stored' co2 in plastic into gas in the atmosphere. Based on similar studies, it does seem that it will off gas far more H2 than CO or CO2 though --- tl:dr: some scientists got a tube filled it with argon and smashed up microplastics, chucked it in a 500 watt microwave, and got a way to make a lot of money off of graphene synthesis

This information is not intended for minors; by reading further you agree you are over the age of 21. > > DISCLAIMER 2: This is not rigorous scientific research. I conducted this experiment over the course of a work day, carrying out my actual work while trying to not arouse suspicion. I did not have time to create a calibration curve to conduct quantitative analysis. Further, isolating samples and using IR and NMR to identify impurities would increase my chance of being found out by coworkers. I also forgot to collect a data point and made another mistake that I explained in the “results” section that I did not have time to correct. That being said, these results are roughly accurate and I am using them to inform my own DIY HRT. > > This is somewhat of a follow-up of [this post on DragonOrdnance estradiol enanthate](https://hexbear.net/post/1419643), and I plan on posting every year with stability data for prepared solutions when properly stored (cool, dark, dry). Since I have 10 vials with 7 mL each, I have enough to provide over a decade of stability data. I also have leftover powder which I also plan on testing yearly. > > Abstract: > > To improve the safety of the DIY transfem community, it is necessary to demonstrate the thermal stability of estradiol esters to ensure DIYers properly sterilize injection vials. Without an autoclave, a higher temperature is necessary to destroy all bacterial endospores that may be present. Estradiol enanthate (EEn) has considerable thermal stability and can be sterilized at home without the fear of decomposing the EEn. At the suggested home-sterlization conditions of 130degC for 30 minutes, no decomposition was detected. Even at 180degC for 1 hour, less than 5% of the EEn decomposed into an unidentified compound. Light exposure also has minimal effect, with no decomposition detected after six months of continuous exposure to artificial light and indirect sunlight. Home sterilization is recommended to avoid infection. However, it is recommended to store both EEn powder and EEn solutions in a cool, dry, dark area to minimize the decomposition of EEn over longer periods of time (EEn powder is shelf-stable for five years and likely much longer). A follow-up study will focus on long-term stability of properly stored EEn powder and EEn injection solutions. > > Introduction: > > Last week, I saw a post about a comrade who started HRT and mentioned their sterilization method (130degC for 30 minutes). A discussion in the comments included users suggesting that estradiol enanthate (EEn) would start to decompose at 130degC. This surprised me, as I remember seeing somewhere that estradiol ester injection solutions can be sterilized at higher temperatures than an autoclave (121degC) without significant decomposition. This is important because autoclaves are effective not only for the high temperature, but for the elevated pressure as well (~30 psi, or ~2 atm). Therefore, slightly higher temperatures are required to effectively sterilize injection vials. DIYers likely don’t have access to an autoclave or any kind of pressure vessel, so to improve the safety of transfem DIYers, I aim to alleviate concerns regarding the thermal stability of EEn. > > I have a considerable stash of EEn powder that I purchased 1.5 years ago (likely over 2 years past its manufacture date) and I have an injection solution I prepared in bulk, originally intending to prepare vials as needed. This bulk solution has not been subjected to heat but has been on my desk at home where it’s been subjected to artificial light and indirect sunlight (light, like heat, accelerates decomposition of EEn). In this experiment, I determined the stability of EEn under various conditions: as a powder and a solution, and after exposure of the solution to light and/or heat. > > Methods: > > All injection solutions were prepared as 50 mg/mL EEn in MCT oil with 2% (v/v) benzyl alcohol. > > The EEn powder, MCT oil, and benzyl alcohol were kept at room temperature in opaque, resealable plastic bags since receiving them 1.5 years ago. The light-exposed injection solution was kept at room temperature in a clear, resealable plastic bag where it was continuously exposed to artificial light and indirect sunlight for 6 months. Two more injection solutions were prepared the same day as this experiment to represent injection solutions that have not been exposed to significant light. > > The “light-exposed solution” was analyzed by GC-MS. Then, the solution was sealed in injection vials and the vials were placed in a GC oven at 130degC for 30 minutes. This “light-and-heat-exposed solution” was analyzed by GC-MS. > > One of the freshly-prepared solutions was sealed in injection vials and placed in a GC oven at 130degC for 30 minutes. This is the “heat-exposed solution”. The other freshly-prepared solution was transferred to an open test tube and subjected to a 180degC oil bath for 1 hour. This is the “high-heat-exposed solution” and represents the worst-case scenario of a DIYer sterilizing at a temperature far beyond what is necessary. > > Results/Analysis: > > The chromatogram of the EEn powder suggests this is a high purity sample, as the only peaks are EEn (at 26.4-26.9 minutes) and the MCT oil from previous analyses (Image 1) This EEn powder was analyzed following the analysis of several EEn solutions, and the needle wash was empty, so there were three other peaks that were confirmed to be triglycerides from the MCT oil residue on the needle. There is also a solvent peak (acetonitrile) at ~1-2 minutes. The mass spectrum is consistent with that of EEn (Image 2). > >  > > Image 1. GC Chromatogram of EEn powder > >  > > Image 2. Mass spectrum of EEn powder > > Image 3 demonstrates a newly prepared EEn solution that was exposed to light and atmosphere while being heated at 180degC for 1 hour. Samples were diluted by adding 1 gram acetonitrile for every 10 mg of sample. As the samples were at the same concentration, the peak area of the EEn peak is a reasonable (though rough) measure of the remaining EEn. Before heating (t= 0), the peak area was 186.0 M counts. At t= 15 min, peak area was 184.9 M counts. At t= 30 min, peak area was 178.7 M counts. At t= 1 hr, peak area was 195.4 M counts. The peak area at 1 hr had the highest z-score at z= 1.5324, giving a p-value of .1254. This indicates it is very likely that the variations in these measurements are due to chance. The chromatogram at t= 1 hr demonstrates the production of a decomposition product, but the peak area of this decomposition product is <5% of the area of the EEn peak (Image 4). > >  > > Image 3. High-heat solution chromatograms > >  > > Image 4. High-heat solution chromatogram at t= 1hr, zoomed-in to visualize decomposition product peak > > The following three chromatograms represent the light-exposed solution that was not heated (Image 5), the light-exposed solution that was heated at 130degC for 30 minutes (Image 6), and the newly-prepared solution that was heated at 130degC for 30 minutes (Image 7). > >  > > Image 5.

Chromatogram of EEn solution exposed to 130degC for 30 min, but no light exposure > > In absence of rigorous quantitative analysis, the proportion of peak area of EEn to benzyl alcohol was used to compare the decomposition of EEn. The concentration of benzyl alcohol in these solutions was constant, so it is another reasonable yet rough estimation of remaining EEn to determine if decomposition occured. For the light-exposed/no-heat solution, the EEn peak was 68.99% the area of the benzyl alcohol peak. For the light-exposed/heat-exposed solution, the EEn peak was 68.41% the area of the benzyl alcohol peak. For the no-light/heat-exposed solution, the EEn peak was 68.20% the area of the benzyl alcohol peak. These values are not significantly different, indicating that decomposition did not occur in any of these samples. (I forgot to measure the peak areas of a no-light/no-heat solution, I’m sowwy :(, but you can look at the 180degC data to see that no significant decomposition occurred at 30 minutes at such a high heat). > > Conclusion: > > According to GC-MS data, no significant decomposition at normal sterilization conditions (130degC for 30 minutes). Even at 180degC, EEn is fairly stable, remaining 95% intact after one hour at this extreme temperature. Light exposure is also a minimal risk, as no significant decomposition occurred after six months of moderate light exposure.

Hey folks, the results are in and the vast majority of active Hexbear users say they are *not* cishet!  This survey had the same limitations of our previous [transgender survey](https://hexbear.net/post/2226865?scrollToComments=false). This means we do not have the tech to make this survey more accurate through other means (more questions, more options, negative/positive answering, anonymous answering, etc). However, we *do* have a good sampling of the active userbase (about 1/3rd of daily active users answered) and combined with the transgender poll, we can conclude that Hexbear is an overwhelmingly queer instance that is proud of stating its queerness publicly. You can see the graphs of the previous transgender survey here:  --- You can find the raw (public) data of the survey [here](https://hexbear.net/post/2664304?scrollToComments=false). Feel free to audit my numbers and make sure I didn't hallucinate anything! The total tally was ``` Yes = 114 No = 195 Unsure = 30 Total = 339 ``` A number of people did not follow instructions properly, and I put them into the category that made sense based on the information they provided. A number of people used the dean-malice emote which was not in the set of emojis I provided for responses. Most were merged into yes, unless they stated they were queer otherwise. This survey is a little less complex than the last one, I kept it short and sweet and did not tally the pronouns. Both surveys were done over three days and were pinned on the front page. --- P.S. Thanks [@ComradeEd@lemmygrad.ml](https://lemmygrad.ml/u/ComradeEd) for helping make this a bit quicker with your code [here](https://hexbear.net/comment/4974925). I hope you all have as much fun with this information as I did and I hope you all have a great Pride Month

Hey, we *still* haven't been able to find a secure way to poll everyone yet. I've really been wanting to ask (in the negative, to be more inclusive) what proportion of Hexbear is queer. This isn't going to be super scientific or anything as a result, but just a quick guess. Please respond to this post with the following emojis : **For yes, you ARE a cisgender heterosexual (cishet):**  **For no, you are NOT a cisgender heterosexual (cishet):**  **For unsure, as in you are UNSURE or QUESTIONING if you are queer, transgender, a cisgender heterosexual (cishet), etc:**  If you have anything to add, please use a spoiler tag below your answer like so: ::: spoiler spoiler hi! ::: # Remember to respond even if you are cisgender, queer, or otherwise. Everyone should try to respond, if you feel comfortable!

  Tennessee has recently passed a bill, effective July 1st 2024, declaring it a class-C felony to "recruit, harbor, or transport an unemancipated minor within this state" for transgender healthcare procedures, carrying a sentence of 3-15 years in prison. This applies over state lines and states that do not have anti-extradition laws relating to trans rights can extradite you to Tennessee. Notably: the bill is vague. This means: telling stories of your own transition, describing your healthcare experiences to an open group chat, describing your trans experiences on a public website, creating trans health guides online, describing how you have gotten DIY HRT, describing anything to do with trans healthcare, even as a cis person, *can* result in a class-C felony conviction. Given that being arrested in any capacity for transgender people can be an incredibly dangerous experience ([CW: SV](https://archive.ph/qeV2U)), I *strongly* suggest you begin caring about opsec, stop referring to where you live, use VPNs, stop using apps like Discord, and stop using social media sites that track your IP or user agent fingerprint while unprotected. Remember that for a bill like this to be challenged in court, you have to be arrested first. Will discuss creating / linking to a transgender matrix chat so that we can help people to move off of things like discord.
