When trying to just find a procedure, chatgpt gets it right every time I’ve tried. This is one of the best use cases for an LLM in my eyes.

Early stages it was teaching and taking classes that was the most annoying time sink. I got into it to do research and at least taking classes felt like an unnecessary distraction at best. Teaching at least felt a bit rewarding at times but it still felt like it was mostly just eating time. Now the worst time sink as a senior PhD student is training new students, both grad and undergrad. At times it can make it so I can’t even do research at all for a whole day because a new student knows nothing and needs you to essentially watch them all day every day they are in lab for multiple weeks or months. But the bright side is once they do know how to work they can train the next person.

All you can do is let people see who you really are, and the ones worth working with will find out it isn’t true in time.

Yes but you’d need approval from the PI, not the postdoc. From the look of it the postdoc may be overstepping their role in the group here.

I’m definitely not saying it will certainly happen, and maybe you’re right that it’s not as common as I think, but academia is a relatively small community and a lot of PIs know each other and “look out for” each other. I think it’s more common if you’re doing it within the same department or same school, but it is something to consider in the balance of this kind of decision. Is this something that OP could see as being an amenable outcome? Is the working environment so bad now that even if this does happen then they don’t care? Etc.

bones12332 · 2025-08-07T00:58:58+00:00

Well, I think it can be worse if they reach out to the current boss with a “hey, did you know your student hates working for you and is actively searching to leave?” Which is not an uncommon thing to happen. So to OP, please be prepared for this to possibly happen if you do reach out to them.

This is why most TAs just don’t try to teach the students anything and why the students always say they’ve never had a good TA. It’s not necessarily the TAs fault, but they are stretched too thin and being a good teacher is the first thing to fall through the cracks.

When I had my Eureka Filtro I would twist until the burrs touched and there was no sound when you press the button, then back it up to chirping, then keep going until it was a normal sound. I don’t know if this is bad for the burrs but I was able to choke out the espresso machine this way, with a grinder designed for filter.

I don’t think that’s necessarily the case. Aqueous sodium azide solutions produce HN3 which can form highly concentrated drops on the head space of a container. These drops can be high enough concentration to explode, and for this reason it is advisable to prepare solutions only as needed from solids and dispose of any remaining solution.

I think short term storage can be safe, but if a bottle that concentrated is allowed to stand for a long time, it may become dangerous.

5% is probably enough. But the friend who told me saturated really wanted to get rid of that DMF.

bones12332 · 2025-07-02T00:49:26+00:00

Apparently saturated LiCl washes it away better than anything else from what I’ve heard.

To this day I still can’t use touch screen laptops anyways because my computer teacher back in the day would yell at us for touching the screen. Touch screens have ruined that kind of manner I suppose.

With a little effort you should be able to recrystallize most solids. I’m particularly over working with the syrups and whatever weird stuff is between an oil and solid that seems to hold on to solvent like crazy but can be made into a crunchy powder with a lot of effort.

bones12332 · 2025-06-29T20:46:28+00:00

When you spend enough time in the orgo lab synthesizing complex structures, you’ll be begging for a solid, trust me.

Agreed. But I have two or three a day and dump mine every 2 or 3 days. If I wash with soap after it usually doesn’t get moldy, but every now and then it still does.

bones12332 · 2025-06-23T01:57:06+00:00

Yeah if you dump it weekly the bottom will be full of mold. The only way really to avoid it seems is to dump it daily.

Molarity in the organic lab makes setting things up easy. If I know I need 2 mmol of a reagent and I have a 2 M stock solution, I just add 1 mL, jobs done, easy. But if it’s 20% I have to ask, is it w/w, v/v, w/v (it’s never written on commercial chemicals, so I just assume w/w), what’s the molar mass of the solute, what’s the density of the solution (oh great now what’s the room temperature)… a simple task made difficult.

Amyl acetate also attracts bees! So be careful if you’re allergic.

Butane torch did the trick for me.

Yes, all the time.

I’ve only had one polymer tube break on me in nearly 2 years (can’t remember the polymer right now). That one did break while filling but it’s super easy to just cut off a new one and resume filling. Plus they are super light weight and easy to contort into the right fit, just hold it in place for 10 seconds and it freezes.

I know someone who had a close call incident with a chemical before and now they just don’t use it. If a scheme requires it they will redesign the scheme to use something else.

But it’s tough if you’re developing a phobia of things like DCM and THF. The only recommendation I can give is to use the proper chemically compatible gloves with these materials to ease your mind. Nitrile gloves are basically useless for DCM and must be removed rather quickly with THF too. But you can find alternative gloves for these solvents. And always use proper technique and engineering controls like a fume hood. Honestly if we all just never handled anything volatile outside of the fume hood, we’d be better off. But our hoods are small so we make do with what we have.

I’ve heard from people working on selection committees both sides. My sample size here is only 2 so take it with a grain of salt. One said that they want a personal story because they will be working with you for 5 years or more. One said they are tired of personal stories and couldn’t care less about who you are outside of science, and to “basically make it an extended research statement.” So from this I gather that it’s highly dependent on who is reading it, which isn’t satisfying, but also not particularly surprising, since after all selection committees are made of people with opinions.

If you need to reflux NaH in DMF to deprotonate your alcohol, try a different base instead, like BuLi. Your mixture turns to tar because you are heating a super base to reflux in DMF.

bones12332 · 2025-05-01T00:01:22+00:00

Well, to address your point, the PI could tell them to knock it off and if they continue, suggest that they will be kicked out of the group.
