[@tildessmoo]

@@Gwallacec2 Olive oil is seed oil, just fyi. Well, seed-and-fruit oil, anyway. But I get your meaning, it's cut with cheaper oils, and... That's only kinda sorta true sometimes? (Or maybe it's moreso in Australia, idunno, my only experience is in the US.) If it's not pure olive oil, it can't say "pure" or "pressed" or "virgin" olive oil (not to be confused with "extra virgin," which is the expensive olive oil you do want for your kitchen but don't want for this experiment), and if it's not 50+% olive oil, it can't be labeled "olive oil," just "blended oil" or "oil blend" or "olive-flavored oil." Basically, if it says "100% olive oil," and it doesn't say "extra virgin," (first cold press) it's probably good; if it doesn't say "virgin" (second cold press) at all, probably better.

One problem is that nanoparticles are "sticky" and will aggregate and settle out (they are never really in solution, it's just that 5-100nm will remain colloidally suspended for a long time). The TOPO used in most of the common preparative methods serves to cap the particles to prevent aggregation. So, I suspect that any NP you may have made aggregated and were spun off with the rest of the gunge. Some literature demonstrated surface passivation with free fatty acids (oleic, stearic, etc.) so maybe it would be best to try this with oil (or lard, in the case of stearic acid) that you have first separated into free fatty acids and glycerol (via treatment with acid or base). You were getting there (conceptually) with the sulfuric acid, but probably didn't make much free acid...also, there was probably loss of CdSO4, which is likely insoluble in non-polar solvents. It's been a very long time since I ran this reaction, but I seem to recall using sodium selenite (e.g. selenious acid) as a nice source of selenium--that doesn't seem difficult to either acquire or prepare. Best of luck, this one was satisfying (I mean, using a UV-VIS to calculate particle size?! Brus...) to pull off.

[@pablodg360]

hi, spanish here. Just to mention, usually, when a olive oil is more expensive, it's less pure than the cheapest one. That's because the "virgen extra" denomination means that all the olive oil was extracted only using mechanical methods, which are less efficient to extract the olive oil. But, extracting in that way it keeps some of the hues thats makes it more valuable in cuisine. The refined oil, the cheapest one, it's obtain by a combination of methods (mechanical and chemicals, mainly) that makes it more pure, but have a bland flavour.

[@isaacw4005]

I've done some research on olive oil standards in Australia (riveting stuff) that may be of help. First off, the standard for extra virgin olive oil requires that there is no more than .8 grams of oleic acid per 100ml so the mono saturated fat line cant possibly be only oleic acid and can't help us, however you do still probably end up being correct that the fancy olive oil is worse for you because the cheap stuff was only olive oil, and that has a maximum oleic acid content of 1g per 100ml. Now the helpful part, there is a standard for "olive oil not fit for human consumption", and that specifically lists an oleic acid content higher than 3.3g per 100ml. I'm going to guess that the paper used that kind of oil, though if it came from Poland I have no idea what standards they set. If you really want to use store bought oil, "Ordinary Virgin Olive Oil" has an acid content of 2-3.3g per 100ml which is notably higher than the maximum content of US olive oil that is considered fit for human consumption at only 2g per 100ml.

Though because you were using heavier elements it was happening faster.
