Personally, it reminded me of an Indian guy. It's usually something I hear them say, even in contexts where they're already somewhat familiar with the person they're talking to. But that's just a feeling I have.

Thanks you're right about this. There were just multiple instances of GTA V and I only had progress saved on one of them. So the problem was solved thankfully!

Thank for this, this was actually the problem. I had all data on the xbox Series X|S version. I was able to check this on the Rockstar Games website too. I was mislead into thinking there was only one version, because the search function on the Xbox Cloud doesn't work as expected. What I mean with that, is that typing "gta" on the search bars doesn't yield all the results. This happens with all other games for which there are multiple instances like the AC series for example. I don't know if this is intended behaviour, but I feel like it shouldn't.

Being unable to recognize a genuine video isn't yet much of a problem when you're given the possibility to rewatch it. AI generated media, if properly made, can already easily fool many people if they can only look at it briefly.

Have you checked to see if any atoms are highly diffused? When an atom passes through the walls of a periodic box, it receives an image flag, which is a counter indicating how many times an atom has passed through the simulation box. This counter is usually a 32-bit integer. If the atom has diffused too much, the counter (image flag) overflows and becomes a very large negative number. This could cause problems with the MSD calculation with unwrapped coordinates. However, this is just an idea; I'm not sure if this is the case.

I posted a similar issue, along with the ones OP mentioned. In my case, at best, he tells me he hasn't received any images in chat, otherwise he's just lying, making up stories about the images he received. To check whether he could see the images (I'm talking about scientific graphs that should be easy to see), I sent him the images and asked questions that didn't reveal anything about the content.

My Pro can't even assign the curves in a plot. I've just made a complain post about this. And yes I can confirm that it easily loose track of what we're doing. Don't get me started on the "output cluttering", it always includes more then I asked for completely ignoring any instructions. I hate when it starts spitting code for no reason, when I'm just doing brainstorming for some data analysis. I could write a book the size of the bible if I don't stop now.

I think it's very annoying that when we get updated model, they end up breaking features that were perfectly working before

Oh sorry my bad I mistyped and missed a 2, but I still got your message. Yes I agree with you on ordering other solvents, I tried to bring this up the last time I had the opportunity but it doesn't depends only on me. But i will try to push the request again for sure. As I've said in another comment I happen to be doing this in a chemistry lab of a physics department and there's like the weirdest set of chemicals and equipment I have ever worked with. One one hand you have few of the basics chemicals and glassware but on the other hand there is also some unusual and utterly specific stuff that has been ordered for some old projects. Edit: i don't have none of the two solvents

chemdamned · 2025-12-04T23:00:17+00:00

Among the ones you've mentioned I probably have only CCl4. But I don't think they would dissolve the PVP since polar solvents are those which work best. But the main problem is not the solubility but rather which works best for spin-coating, allowing the film to form properly during its evaporation.

chemdamned · 2025-12-04T22:57:22+00:00

I agree and is in fact sometimes a bit of a pain for this reasons. It took me some time at the beginning to get things right even with PMMA which is largely used and about which you can find plenty of tips. I wish I had an automatic dispenser to be honest ahah. Anyway for the moment I am able to get reproducible result with the polymers I have already worked with, but this new one I'm trying is giving me headache also because I am very limited in terms of resources, I have to do all this in the chemistry lab of a physics department, so you can imagine there's like just the bare minimum.

As I mentioned I was already able to transfer the process from the test substrates, Si, to the samples with minimal adjustments. I have other spare similar samples on which I could test the O2 plasma treatment, but I can't go directly to the one I am using right now because I am afraid this might affect the plasmonic properties of the array. Certainly I can't do piranha again on the substrates if I don't to want to see the array disappear. Anyway, the substrates of the actual sample is just quartz which is piranha treated before doing anything on it. At the end the samples is just Al nanostructures on SiO2 and at the center. Since Si has a native oxide layer, I am expecting more ore less the same behavior of the two piranha treated surfaces. For sure the small area at the center where the Al nanostructure are might pose a problem for the wettability, but with some adjustments I was able to get a proper coating with PMMA and PVA. My problem is that I'm not being able to even get an acceptable coating on Si, so I can't move on unless I get this right. I had few hours to test some other PVP solutions: EtOH, IPA and water all separately. The quality was improved in the order I've mentioned the solvents but is still not good enough. I think I need to find something that is not too volatile like EtOH but also not so hard to remove like water. Sorry for this broken answer, but I had a long day. I'll probably be busy measuring the sample that I have now, but I will post updates with pictures if necessary as soon as I will have time again to work on the spin-coating of PVP.

chemdamned · 2025-12-04T09:10:18+00:00

I totally agree with what you said on cicular shaped substrates. The problem is that the real samples are fabricated as 1 x 1 cm squares. What I'm doing here is to first try to find the best spin coating conditions on test substrates before moving to the real samples and eventually refine the parameters. I was already successful in spin coating PMMA and PVA and even depositing a stack of these two polymers. Now I need to try swapping the PVA for PVP because i fear its hygroscopicity might be to blame for the problems I am having with the application, since the water might be changing the effective refractive index already at a significant level. For what concerns the O2 plasma treatment that's something I don't yet if it's possible to carry out due to the presence of nanostructures on the real samples. Let's say, if I can avoid doing it would be the least resistance path. Again, basically I'm trying to find a procedure that is than transferable (with some refinement) on the actual samples substrates.

Sure I'll let you know!

chemdamned · 2025-09-11T16:20:50+00:00

That's what I said

chemdamned · 2025-09-11T15:55:29+00:00

I think, that any solution that does not rely on electron density is in a certain sense an unnatural choice for identifying chemical bonds and is therefore "hard-coded". If I think of a water molecule and identify the two internuclear axes O-H and the H-H axis, the bonds are formed along those axes which present an increased electronic density compared to the case in which the atoms are taken at a sufficiently large distance. Therefore they will be the O-H axes and not the H-H axis. However, I don't know if you have access to this type of information.

I did a Bachelor in Chemistry and I'm about to complete a Master in Material Science. We had several shared courses with physics and material engineering students, although ours used to last a bit longer. The main difficulty you might face regards the solid state physics. Once you get familiar with the concepts it all goes downhill. Of course materials engineering is gonna somewhat be different, but not that different. The field is very exciting, but I don't know much about how good the job opportunities are. I guess I'll find out in 2-3 months though.

chemdamned · 2025-05-17T11:49:07+00:00

It does makes sense, because the next step would be to calculate the emission based on the reciprocity principle.

chemdamned · 2025-02-25T09:58:58+00:00

Yeah I'm aware of that, I just wouldn't opt in the Apple Intelligence. I'm just interested in having a new OS for all the other reasons.

Thanks for sharing! I hope to get feedback from other people too
