What does Anon use to predict NMR?
I'm currently using Mestrenova which is a step-up from ChemDraw but still lackluster.
I'm looking for something that doesn't need to run on a server farm but is still decent enough to serve as a guideline when interpreting spectra.

Oxycodone Reactions Summed up Neatly

Okay, so we had a failure with the reactions of oxycodone with a fucked up friend of mine a while back. He had given me some failed hydrogenated species of 14-hydroxycodeinone which was one of the weirdest highs I have ever experienced in my life. I think I took around 25mg of it.
I think that was a weird kappa-agonist with some mu-effects.

Regardless, a few things that make the last thread obsolete are as follows:
  1. 14-hydroxylation of any morphinan requires the double bond at the 7th position for the enol to occur. Otherwise, the oxyacid cannot form the tertiary alcohol due to lack of reactivity.
  2. Acetic protection group seems to be the easiest way to create 14-hydroxy on the morphinan groups. It has the most yield if not starting from thebaine. The next best thing would be an annoying Cobalt (III) salt which I never knew existed. It seems like this unstable salt can be used as a catalyst for codeinone > hydroxycodeinone. But it's really annoying to make.
With no protection, the yield is an atrocious 20%. With the protection, you can get the yield up to 80%.
3. Almost all side reaction waste products are water soluble after basifying. Unless you're unlucky, there is little requirement for columns during these reactions.
4. You cannot avoid hydrogenation if making oxy from cod.

In summary, unless you want to follow the method step by step on the erwoid page that summarises Codeine > Oxycodone, you won't produce nearly the same results with the available chemicals.
With no protection, you could easily achieve a 20% yield of oxycodone from codeine.

He's also currently working on a more efficient method to oxidise codeine to codeinone (hopefully using bleach and vinegar), a more efficient method to hydrogenate, as well as a better peroxy-acid to put the 14-hydroxy group on.

Pic related. Artefacts. We need those 1900 German artefacts that tell us how to morphine.

Thants (our br/opi/ in Canada) has recently nodded off W-18, which is a totally novel opioids that hasn't seen street time. So /chem/ might as well talk about it.

The current method of synthesis is outlined in patent no. US4468403
>A mixture of 1-phenylethylpiperdylidene-2-(4-chlorophenyl)sulfonamide (1.17 g, 3.11 mmol) W-15, 90% fuming nitric acid (3.0 ml) and concentrated nitric acid (2.0 ml) were stirred vigorously for 4 hours at 25┬░ C.
Preparation of 1-phenylethylpiperdylidene-2-(4-chlorophenyl)sulfonamide is not outlined, unfortunately. But it's pretty easy to figure it out as it's a straight chained molecule.

So uhh ya. W-18. Talk about it. It's legal everywhere except in Sweden right now. I guess that is a thing. It was discovered by Knaus back in the 80s who was a pretty sick guy who liked opioids. He's had a lot of work doing shit like that. Here's some condensed reading:
http://chemistry.mdma.ch/synthforum/about635.html

W-18 is the 18th item on his patent list: http://www.google.com/patents/US4468403
It includes up to 35 different, unscheduled, and very potent, novel opioids that do not rely on the morphinan group. Check em.

High school chemistry class, we were working on a lab where we had to make little squares on a piece of plastic to perform tests in, and the squares had to have 2 cm long sides.

This kid at my lab table, who had already proven to be not so bright in class many times beforehand, got our teacher's attention, then asked what a centimeter was.

After the teacher thoroughly explained what a centimeter is, and where exactly to find them on the ruler in front of him, the student turned to us and said:

"I'm still not understanding this centimeter thing."

Considering grad school

So I'm considering getting a master's in chem. I have always enjoyed chemistry, but I majored in liberal arts. That being said I recall a fair amount about it from taking AP chem in high school.

In any case, I'd mainly like to focus on materials science because I have some experience with machining and fabrication. I'm also thinking I'd end up in education, because I like teaching and that seems like a solid way to go in terms of job security and salary.

Really I'm just looking for advice here. I love chemistry, but I'm pretty damn rusty and I have no real college experience - AP chem in high school is generally a lot easier than an actual college course.

First steps? Things to consider when looking at programs? Any and all tips or advice would be appreciated.

I mean you could take some more classes. College chemistry is nothing like high school though. Basically you've taken at most two semesters of college chemistry. You'll basically have another degree.
I think to be a high school/ junior high teacher you could get by with maybe about gen chem (2) + o chem (2) + p chem (1-2) + inorganic + quantitative analysis + math + physics (2). This is only the minimum possible requirements of course (I'm sure most colleges will require much more). So, not to dissuade you but, there would be quite a few classes that you would need to take first even for a bachelors degree. On the plus side, you'll have all of you're generally classes covered.

As far as master programs go, you're adviser will end up mattering a lot more than the college will. Choosing a good adviser who is well known in the field and is easy to get along is what you're looking for.

Anyway, worth pointing out that chemical engineers have good job prospects and will probably end up taking quite a few of the same courses.

What? That's not how you pick your master. You find a complete asshole who knows his shit and hates his students, and you make that motherfucker laugh every damned moment you get the chance, except the times he's trying to focus.

The reward is that he teaches you, at the expense of the annoying dipshits you compete with. He'll probably even show you things he shouldn't too, just in hopes you use it.

the technological singularity is discussed and well known enough but wouldent the same assumptions more obviously lead to a biological one (assuming we are around after the former). the tech one is basically the unknown after we create a computer that can create a better computer than we can. however a computer (unless we specifically design it to) is not necessarily interested in procreation or its own survival. a biologically altered human though would probably still have those drives in tact (unless we remove it). not that an AI cant value itself and wish to spread or a modified human couldent do the opposite its just that its less likely. both are likely to be started by us but probably completely with very different motives. a biological organism -such as ourselves- is designed by evolution to spread and we may consciously remove that whereas an AI could develop it but it isnt an integral part of its original form. we are moving to a point where we can program genes almost as easily as we code an AI thus the exponential improvement in ability is just as feasible biologically as digitally. consciousness dosent automatically lead to a desire to continue; the childless humans (and more so the suicidal) have evidence to share on this. why should an intelligence, without an inbuilt need for survival and legacy, necessarily adopt both?
fundamentally wed be in the same boat as with machines in hoping they dont turn against their creators but in practice we are more likely to empower and pass on our need to continue to the latter. hell, we might even be cheering it on; it would be much easier for us to embrace designer babies than really advanced software.

tl;dr: we will soon be able to make computers that can make better computers than us. after a slight time lag we will be able to create humans that cant create better humans than us. the former will have the advantage of being earlier but the latter is more likely to be inherently interested in advantage and promoting the same.
not that its even automatically a bad thing since our creations will exceed us (by definition in this case) and will be able to do more than us. they probably wont automatically (see what i did there?) feel a need to turn on us and may well consider themselves part of us in both cases.

The danger of malicious AI doesn't lie in the Matrix type robot rebellion tho. It's more about whether AIs will fully understand the implications of their actions in the same ways we do. Unless you simulate a human brain, AI won't ever be human. It will be something else entirely.

For example, lets say we program an AI to protect and take care of us. The AI's prime directive is to keep humans safe, so true to it's programming it traps all us in a never ending stasis. It has our best interests at heart, yet it effectively ended humanity. Or you make an AI to perfect some product, and it decides to use the entire planet for computational substrate in order to do so.

Kind of a cop-out, but you get the point right?

That's essentially the premise of the grey goo scenario which was dreamed up by Prince Charles. It's plausible but you'd have to fuck some shit up badly to have it happen. Bear in mind that for it to occur you have to have that sort of tech in the hands of fuckwits, and if fuckwits can get it, then there's more powerful technology in the hands of other people who are more competent and aware of the dangers.

I get your point but you're talking about design faults. People will test and experiment and build failsafes on anything that's high risk enough and only roll out something that can end life as we know it if they already have a way to stop it.

Anyway I think that it's also quite possible we'll merge with the machines. Superhuman humans will just be a stopgap or an option for people unwilling to become a sentient nanobot swam or join the network.

I'm guessing you dont meant a log scale, just a 1 - 10 type dealie?
Seems like a good idea, i'll give that a playaround in excel.
Also, if I on the X axis I was measuring 4 different pH values, it would seem to make sense to just label them via the tube numbers.
However, apparently that is not acceptable for the report i'm writing.
I can't exactly label the X axis as pH either, as i've already got values for that on the Y axis and the Series.
Any advice would be much appreciated.

in excel you can use atleast two different y-scales.

and im guessing that youre plotting a titration?
in that case id say that the pH has to be in the y because it depends on the volume of added solution

Of course! I'm sorry, I should've led my post with that.
I'm writing a report for an experiment I did in my Intro To Pharmacology class.
The experiment is, "The Uptake Of Salicyate Into Yeast Cells".
It's to demonstrate the phenomena of the passage of weak acids and bases between lipid membranes.
The report centers on the manipulation of the Henderson-Hasselbalch formulae in order to determine the concentration of salt [A-] within the yeast cell.
I've managed to create a graph of the standard curve with no trouble (R2 of 0.9989, very pleased about that), but the last graph showing the relationship between pH, [Salicylate] and [Salt] (both inside the cell and the supernatant) is proving trickier.

And should I travel to a prestigious University to study? or study at the University in my own home town. Any advice is much appreciated as I am having a hard time with these decisions and 3 years is a big commitment and I dont want to finish one then look back wishing I chose the other one. I am Australian if that matters. Thanks

Presumably it would eventually kill microbes.
One common means of transforming (aka introducing plasmids) into bacteria is elctroporation, which is essentially zapping bacteria with pulses of electricity. These pulses generate small pores in their membranes, into which plasmid DNA slips in.

However this is done in a highly controlled setting, high intensity bursts, and even that produces holes in their membranes, and even that kills alot of the bacteria. Its assumed that even if only 1% survives, in a culture of >1million cells thats no big deal, you still have 10000 cells that will produce viable colonies.

Now, after that little tangent, electric currents are used as a form of chromotography known as electrophoresis. Essentially when you run DNA or protein gels you separate by size based on charge. Since most molecules in the cell are either negative or positively charged, you would essentially tear the cell apart based on the charge of molecules within it. Even the membrane would be torn apart as the negatively charged head groups are pulled toward the cathode, with basic proteins pulled toward the anode.

Student here, I'm taking a calculus based physics course and it's ruining my life. Literally spend the whole day, roughly 6-8 hours working on physics problems daily because of the overwhelming amount of work that goes into our grade. To the point that I have been neglecting my other subjects and my grades in those classes are slowly going down, except physics.

My question is, is there any tips or advice on how to juggle such intensive courses and exceed in all of them at the same time? I need to reevaluate my plan because I feel like if I spend less time on physics, my grade will go down since the material is so dense.

Stories of people in higher academia are appreciated. Also tips to unwind and not let physics ruin your life.

For example, I worked on 8 hours of crunching problems in my problem set all day. Now that I'm home, I feel the need to continue but my brain feels like mush.

PS.

I take adderall on the weekday and I don't have ADHD, just because I want to pass this class.

Classes like these are built to be extremely difficult and made to be frustrating and shitty, anon. Don't put too much of your personal worth into getting great grades in classes like this, just try to get a mastery of the material and work forward from there.

Went from eating mushrooms and smoking dmt to willingly let this get injected in my arm. I've been taking it because it seems to make things normal in my waking hours but dreams are questionable. It's listed as having potential fatal side effects while i'm pretty sure DMT and psylocibin don't.

I was wondering if any chemists could speculate on the structural formula to me it looks very large compared to the simple structures of psychedelics, but i've never studied chemistry.

Here's more about the ingredients: Paliperidone palmitate is very slightly soluble in ethanol and methanol, practically insoluble in polyethylene glycol 400 and propylene glycol, and slightly soluble in ethyl acetate.

Invega Sustenna® is available as a white to off-white sterile aqueous extended-release suspension for intramuscular injection in the following dose strengths of paliperidone palmitate (and deliverable volumes of the prefilled syringes): 39 mg (0.25 mL), 78 mg (0.5 mL), 117 mg (0.75 mL), 156 mg (1.0 mL), and 234 mg (1.5 mL). The drug product hydrolyzes to the active moiety, paliperidone, resulting in dose strengths of 25 mg, 50 mg, 75 mg, 100 mg, and 150 mg of paliperidone, respectively. The inactive ingredients are polysorbate 20 (12 mg/mL), polyethylene glycol 4000 (30 mg/mL), citric acid monohydrate (5 mg/mL), disodium hydrogen phosphate anhydrous, sodium dihydrogen phosphate monohydrate, sodium hydroxide, and water for injection.

So what's your opinion should i continue to take it or go back to using psychedelics.

Hello! Anybody has some idea how could i separate nickel(II) sulfate from copper(II) sulfate with common chemicals and equipment ? I feel like reduction to copper(I) than separation by solubility is the way to go, but i can't think of a practical method.

Ni2+ has a standard reduction potential of -0.26V

Cu2+ is at 0.34V

You can selectively plate either metal onto a variety of metal cathodes using a more reactive metal like iron as an anode... I think. You just dial the cell voltage down until only copper is being reduced.
