Chemistry General #1 Anonymous 09/27/2020 (Sun) 12:47:20 No. 3 [Reply]
First general dedicated to chemistry, chemical engineering and related topics. As long as it is for the most part related to chemistry: post interesting papers, discussions and problems.

>>55 Well shit, the NMR spectra did not look too great. My product is present, but there is acetone in it and the signal is really weak. I hope I can purify it some more, but this might be a problem for future syntheses. A not too shit yield of 75% though, which is good.
>>58 Product was pure but just contaminated. Washing helps a lot. Nearly finished my catalyst, just €1000 and 6 weeks later.
>>59 wet, not contaminated

PDFs, websites, books and channels you regularly use or just enjoy reading/watching.

>>29 Going off on a tangent here but, is there some sort of free and open source program that lets me edit text collaboratively with people? Maybe with features making LaTeX edition easier? I know there's Google Docs, Overleaf which you mention here and maybe a few more propietary/SaaS options, but I want something open. I think VS Code has an extension that allows this, but the distribution terms are murky, and it's developed by Microsoft. I also recall hearing that Atom had something similar, but as you might know, that was developed by GitHub, and GitHub was bought by Microsoft, so it's probably very dead by now.
>>52 LyX is a thing apparently? It uses Git, so it should be open source. I have never seen an out-of-the-box solution for what you are referring to though, since you'd need a central server anyways.
>>53 Well, I mean something more like Google Docs, where changes to a document are recieved and seen by the user in real time. You don't need a central server though, I think Etherpad or some such is P2P. Atom as well.

WEBM / meme / screencap thread Anonymous 09/27/2020 (Sun) 15:11:52 No. 8 [Reply]
Dedicated thread for all of your shitposts and interesting WEBMs of all kinds of science.
13 posts and 39 images omitted.
>>47 I have a lot of screencaps in my archive, but I don't think I've ever heard of that one.
>>48 Basically a bunch of russians were tasked with coming up with a plan to counter something like an invading force that was way more advanced technologically. Basically what can be done if we were attacked by aliens. The funny thing was that they actually came up with a sound plan of what was basically a giant IED that used an atomic bomb to propel a projectile at something like 5 to 10 percent the speed of light.
>>50 You mean a shaped charge. Basically, they dug out a cylinder from the ground, placed the nuke at the bottom, and on the top of the cylinder, at ground level, they placed a cone with its tip pointing towards the nuke. Can't remember what the cone is made out of, but regular shaped charges have cones made out of copper. Not sure if this is something they thought of or it's something they actually made. I heard the americans accidentally sent a sewer lid to space with a nuke, to similar effect, but I'm not sure whether or not this happened.

Post banners > no idea about the extension required (GIF and PNG work for sure) > 300 by 100 pixels > science related of course I slapped one together. As you can see, I am a man of science, not of design.

Disregard the two banners in the OP, I fucked up.

>>35 It's entirely possible that he thought future conspiracy theorists will try to come up on him and claim "he had a patent for it, so he must've been on to something." Like people do now.
Are LENR a meme?
>>39 Yes, except muon-catalyzed fusion. https://en.wikipedia.org/wiki/Muon-catalyzed_fusion If you mean "meme" as in "will not break even" then maybe muon-catalyzed isn't for you. It does let you fuse atoms at much lower temperatures, but you need to make muons first, which isn't trivial, and they decay quickly. This Wikipedia article says some methods have promise, but I bet you my ass that those methods are waaaay more immature than conventional fusion techniques, theoretical studies, actual experiments on the matter (heh), etc.

Provide feedback here, also, rules shamelessly ripped from /t/, deal with it.
>>1 I don't know how you would like to manage the board, but I'll give you some setup and traffic to start things off. I hope you won't mind some different generals and different subjects, so I'll start on some of those. First post other than the BO, let's hope this chemfag can at least draw in some attention.

>>2 Here we go. This should at least give the board some space to work with; I'll return when I feel like posting again because those were a lot of posts.
