  1. I think you have still neglected to include context as some of those questions are not answerable as-is. Briefly: As written, your answer to 1 (a) i doesn’t make sense, or it is just incorrect. It doesn’t specify indium nitrate or metal, but I would read that to mean elemental indium. I assume there is more context here. Also, it is more correct to say it is in group 13 (group 3 is still accepted), but that does not mean the oxidation state is going to be 3+. In+ is also possible, for example. I would also add that saying hydrogen is reduced is not the best wording. Better to specify H+.
  2. Correct. They are listed in the staff directory as an admin and the mods and admin all know who he is, but that doesn’t always mean we can get in touch easily. Honestly, it wouldn’t be SFN if we didn’t let the domain lapse every few years.
  3. Is RP chromatography a possibility? I normally use C18 cartridges on an MPLC unit for any of my peptide work and haven’t had an issue. I would also normally use 20% piperidine in DMF for Fmoc removal, but this is for SPPS so possibly not as easy in solution phase. The other option, which might be a bit much if this is just a single amide bond you’re making or your starting material is precious, is to load it onto a resin and do the synthesis that way.
  4. Thank you, and I’ll say I worked very hard on teaching them how to type / finding an appropriately sized key board, so it’s nice to have my work recognised.
  5. A point I wholeheartedly agree with. There is a lot of literature in the crisis management space that discusses this and treats the increase in frequency and severity due to climate change as a given. The way that plays out in policy is interesting. As a side note, the floods in 2011 didn’t just hit Brisbane either, they impacted roughly 75% of QLD all told. We won’t really be able to know how the damages and costs compare until it’s finished battering the NSW coast, but I would guess you are right that the net effect including NSW (especially Sydney) might tip the net cost over what happened in 2011. It also looks like we’re getting severe thunder storms and giant hail tomorrow up here, so fingers crossed we get through round 2 relatively in tact.
  6. I don’t want to detract from your main point too much, but I have lived in Brisbane through both. The 2011 ones were way worse, but also quite different. Those ones came after months of non-stop rain. They didn’t manage the dams properly and sent a tidal wave down the river when it got to the point where they had no option but to release water. The damage and flood levels were considerably higher in 2011. The house I lived in at the time was thankfully on a hill that became an island for a few days and we were without power for four days, but we were lucky. Even before this weekend there were properties that had not yet recovered from 2011, largely thanks to insurance companies who refused to pay out and people being forced into bankruptcy. These floods came quickly and surpassed predictions, which did mean that people that probably should have evacuated did not. There were a surprising number of deaths, but if I had to guess I’d say the suddenness of it all was at least partly to blame. Properties and areas that didn’t have good drainage suffered badly, but 2011 was still worse.
  7. My assumption is that it is asking you for the masses of each individually to make up a litre of solution with those concentrations and that the first number is meant to be in M. The last bit is an assumption though so I would check that. How much is also kind of vague and not stated but the only way I can think to answer it (it isn’t even really a question it’s just a statement) with that information is with masses.
  8. What reactions have you learnt about so far that might fit? Can you identify where the fragment on the left appears in the product?
  9. While this thread is closed and (I think) being the only person who identifies as female in this thread, I just wanted to provide a little food for thought. Of all the women in my life with whom I am close to, I can't think of a single one who hasn't been sexually assaulted or raped by a man at some point in her life. I cannot say the same about the men I know wrt to false accusations. Anecdotal I know, but something to think about.
  10. I think it’s also important to note that we don’t always agree on a particular course of action such as banning every time it is suggested and will make compromises that everyone can agree to regularly. Conferring with one another isn’t merely an exercise in box ticking.
  11. What, you don’t like rolling 3 month contracts completely contingent on obtaining a portion of the ever-dwindling pools of grant money available? Weird.
  12. After some further discussion, staff have updated the above to now read:
  13. I’ve met a couple of members IRL when I’ve been in the US and have considered them friends at various points. Others I knew digitally when IRC was a thing, and a few I am friends with on FB. These days I generally avoid crossing streams. Difficult to forget that one.
  14. You will need to attempt this yourself before we can help you. What are your thoughts?
