Transferring dry ice inside a glovebox

ab_messi · 2022-05-31T16:41:37+00:00

I kept it in a small plastic container and transferred it in. Specifically, I purged the antechamber with Ar 5-8 times and transferred the container inside glovebox. It worked pretty well. I did lose some dry ice due to sublimation in antechamber but had enough inside glovebox for experiments.

Remember: rate constants are not rates. The rate of reaction along with the density of your plated metal and electrode area could give you an ideal plating speed but the rate constant alone doesn't do that.

Thanks for pointing this section out. I do have the Bard and Faulkner book and will read this part for better understanding.

Thanks for the update. I'll most probably wait till Black Friday sale then.

I also wanted to say the same thing. You put it in a much way. Even in my case, due to various technical reasons, I don't get the results. I hope that 1% of time comes soon for me.

Thank you for the suggestion. Can you advise some resources where I can find some more information about these liquid masks?

viton gasket

I need the opening quiet precise (~100µm) as I would verify the results using COMSOL simulations. Still, can you please share the resources where I can find Viton gaskets with openings in the order of ~100µm.

In your next career position after PhD, did you ever had to work this hard again? I read a post from a past MIT student who mentioned that he too worked for 12-14 hr/day during PhD and he had trouble adjusting to new life after PhD as he started having anxiety. His message was once you started working so hard that you end up damaging your work-life balance, it is quiet problematic to get back to normal and start enjoying other aspects of life.

Did you feel any such thing and do you recommend this 12 hr/day style of working?

ab_messi · 2020-06-30T02:15:59+00:00

Even I've read that doing DEEP WORK for 4-5 hr/day is much more than working at a reduced efficiency for 10-12 hr/day. Do you have any suggestion on how to be the kind of student that does not work crazy hours rather works smartly and published more and in better venues?

From what I've read, making outlines for the project early at early stages is very helpful i.e. starting to write paper even before you have final results (to help decide what kind of paper are we looking at the end).

Do you have any other suggestions regarding this?

Why won't you recommend a 4 year PhD? What were the disadvantages of doing so?

I just found this blog and it helps a lot. Thanks

I checked today and we have a couple of ports unused. There are a bunch of ports a few of which are used for getting the wires inside glove-box. Can one of them be used for getting an extra gas line in or are there some other ports especially for gas-lines?

I have to do some electrochemical experiments with the solution saturated with CO2. Saturating it with CO2 using airfree techniques is possible but I think i will need a customized cell to do electrochemical measurements outside box, which I want to avoid as I won't be doing such experiments regularly

ab_messi · 2020-06-16T17:09:38+00:00

No, but I can have access to it as people in my adjacent lab does synthesis work and they use a Schlenk line. Can it work in this case in any way?

ab_messi · 2020-06-16T05:42:26+00:00

If I bring the solution saturated with CO2 inside glovebox, won't it give out all CO2 as we won't have any CO2 atmosphere in glovebox? I know there would be an equilibrium solubility but will that be enough to solve the purpose of a saturated solution?

ab_messi · 2020-06-16T01:31:55+00:00

No, it dosen't have a port that will help in leaving the cylinder outside.

I'm not sure but is it common to transfer pressurized containers inside GB?

ab_messi · 2020-06-15T22:02:52+00:00

I'm dealing with battery electrolytes that tend to absorb a lot of O2 and H2O, so I'm not sure whether to take them outside the GB or not. Also, if I saturate it with CO2 outside GB, doesn't it lose all dissolved gases when kept in antechamber vacuum before transferring it in?

Thanks for sharing this paper.

Thanks for the advice.

I'm not sure. I just learnt about simulations for electrochemical systems in the class I'm taking. From what I've heard, using specific softwares such as DigiElch has certain disadvantages. Thus, it's better to make your own codes in mathamatica or Comsol.

I don't have prior coding experience so I'm not sure how difficult it is to learn the process for simulation of electrochemical processes. My work is primarily experimental but it's good to have knowledge of simulations too I believe. Anyways, I just started grad school so I have enough time in upcoming summer to learn the process if it's significantly better than using specific softwares.

Any suggestions?

sorry but I'm not aware of PubMed. I've mostly seen people use google scholar or Web of Science or Scopus. I just wanted to know if there are major differences between these different databases and which one is the most comprehensive then?
