Hi Ephemeronium. You might be interested in this WikiProject. --Leyo 15:41, 1 December 2009 (UTC)[reply]

Thank you for your valuable categorization work here on Commons!
What about adding a babel box to your user page? Like that people would know in which language they can contact you on your talk page. I just assumed that English would be fine. --Leyo 15:59, 17 April 2010 (UTC)[reply]

Yeah, good idea. I've been meaning to create a user page for ages. I might get round to it in the next week or so. Ephemeronium (talk) 16:16, 17 April 2010 (UTC)[reply]

If you put there more than just a babel box, that's also fine of course. :-) --Leyo 16:24, 17 April 2010 (UTC)[reply]

The Wiktionary logo vote first round is almost over, and it looks like none of your logos are going to make it to the second round. The bookglobe logo has a lot of support from the Wiktionary community, and the Wikisaurus sub-project has no logo or main page at the moment, so recently I've been working on some style changes to Wikisaurus, which I intend to propose to the Wiktionary community in about a week or so. These include making the bookglobe logo the logo for Wikisaurus (Wikisaurus previously had a logo which was supposed to be temporary, which no one liked, and was removed from all Wikisaurus pages a while ago), making this the main page for Wikisaurus (feel free to edit it), changing the standard Wikisaurus header to the one found at the bottom of that page, and also, if you could provide a small image of just the red globe, changing the bullet points in Wikisaurus entries to look like a smaller version of the red globe. What do you think? --Yair rand (talk) 20:42, 27 December 2009 (UTC)[reply]

Uh, this is the current account of m:User:Ephemeron, right? --Yair rand (talk) 00:37, 29 December 2009 (UTC)[reply]

I'd be delighted if you used my logo (and yes, you have got the right account). Of course I hoped from the start that Wiktionary would choose my logo, but now I can see, at least from the tally I did two weeks ago, that it's not going to happen - I guess I'll never be able to boast to my friends that I designed the Wiktionary logo. But you're offering me the next best thing, which is great. In fact it feels like a late Christmas present. Lastly here's the bullet point that you asked for. Thank you. Ephemeronium (talk) 00:39, 30 December 2009 (UTC)[reply]

I've started the discussion here. Time to wait and see if it goes through :) --Yair rand (talk) 19:32, 5 January 2010 (UTC)[reply]

Thank you for the quick fix! Edgar181 (talk) 14:14, 27 January 2010 (UTC)[reply]

Hi Ephemeronium! I really like the molecular models that you've contributed to Wikipedia! Since I don't know if you're still active here, I was just wondering if you could do a molecule of phosphoglycolate? It's just glycolate with a phosphate group attached. No pressure! It's not like your beholden to me or anything, but I just find your work... aesthetically pleasing (I've seen alot of sloppy models) for the loss of a better phrase. Anyways, keep up the good work!

Lee

Phosphoglycolate (3-)

Phosphoglycolate (2-)

Wow, I am honored to be receiving requests for my molecules! I have made these two images right away, showing different states of ionisation. I hope you like them. --Ephemeronium (talk) 19:17, 6 October 2010 (UTC)[reply]

Dude... you are totally awesome! Thank you so much! Again, really, keep up the good work!

 Info If you like to get more of such requests, just have a look at w:Wikipedia:WikiProject Chemistry/Image Request. ;-) --Leyo 00:21, 7 October 2010 (UTC)[reply]

Just out of interest, what are you planning on using the image(s) for? I notice that phosphoglycolate doesn't have a Wikipedia article. --Ephemeronium (talk) 21:00, 8 October 2010 (UTC)[reply]

Yes, I noticed that it doesn't have a Wiki page, but I'm using it to create a schema of photorespiraton in C4 plants. I hope to make it Wiki-worthy, and once I do, I will totally credit you ;)

In the pictures File:Carbamic-acid-3D-balls-B.png, File:Carbamic-acid-3D-balls-C.png, File:Carbamate-anion-3D-balls.png, you have neglected the free electron-pair of the nitrogen-atom that causes the hydrogen-atoms to form a trigonal pyramidal in stead of a trigonal planar structure.

In organic chemistry nitrogen never forms trigonal shapes. Only trigonal pyramidal shapes (where the yellow lone electron-pair is omitted) or tetrahedral in case of a positively charged cation.

In the case Carbamic-acid, the free negative elecron-pair is attracted to the positive double-bond of the oxygen-atom, causing the hydrogen-atoms to point away from the oxygen.

/Kemikungen (talk) 08:56, 20 October 2010 (UTC)[reply]

I was under the impression that nitrogen forms a planar shape in amides. See File:Acetamide-3D-balls.png and many more. This would be justified by the resonance structures of the amide. I don't think carbamic acid is an exception, as this depiction of its 3d structure shows it as a planar molecule. If it does turn out to be the case, I will look into redrawing them. What do you mean by 'positive double-bond'?

--Ephemeronium (talk) 12:18, 20 October 2010 (UTC)[reply]

Ah, yes you are right. Amides have resonance. I forgot that because it is not shown in molecule models or structural formulas in the way usually done with organic nitrates (like nitromethane). However, I don't think this is the case with the carbamate-anion since the only free electron pair is already involved in resonance between the two oxygen atoms. /Kemikungen (talk) 12:59, 20 October 2010 (UTC)[reply]

I'm still not completely convinced, since another model shows the carbamate ion as being planar. However I've uploaded a second version, which shows it as having the typical amino group structure. Feel free to do what you like with it. --Ephemeronium (talk) 17:49, 22 October 2010 (UTC)[reply]

DMacks (talk) 15:55, 28 March 2011 (UTC)[reply]

Hiya Ephemeronium, I was wondering if you could do a molecular model for me (-: I want to use a couple of models you have already submitted (caffeic and p-coumaric acid) for my project poster but one of the compounds (Ferulic acid) I am using hasn't got one of your brill adaptations. I would very much appreciate it. Cheers Nicola

I'll see what I can do. It might be a while though. Ephemeronium (talk) 08:24, 10 May 2011 (UTC)[reply]

Ok no worries, thank you anyway (-; Nik 12 May 2011

Alright, here it is. :-) I hope it's not too late for you to use it. Also, I checked my files and it seems I haven't done caffeic acid, so here's that one too. Ephemeronium (talk) 12:50, 20 May 2011 (UTC)[reply]

File:Triphosphane-3D-balls.png states "2011-01-22" but was uploaded on May 31. Looks like many recent uploaded chemical-diagrams of yours have this same back-dated situation. Were they transferred from an earlier upload at another wiki? Or maybe hardcoded date in the block being cut'n'pasted? DMacks (talk) 15:18, 2 June 2011 (UTC)[reply]

That would be the date that I made them. They've been sitting on my hard drive for a while. Ephemeronium (talk) 15:32, 2 June 2011 (UTC)[reply]

Gotcha. Thanks for clarifying. And thanks for contributing them! DMacks (talk) 16:12, 2 June 2011 (UTC)[reply]

Oh, it's my pleasure. I'm just glad I have some free time now to do so. :-) Ephemeronium (talk) 16:41, 2 June 2011 (UTC)[reply]

Is File:Superphane-3D-skeletal-sticks.png (and the related ball&stick model) an energy-minimized structure, or is the geometry based on experimental data? The en.wp article on the topic has a ref for the X-ray structure, which would be a good basis for all the carbon coordinates. DMacks (talk) 15:45, 3 August 2011 (UTC)[reply]

It's energy minimized, and probably not very accurate at that. I just push the 'clean geometry' button loads of times until it settles on something plausible. And whatever this reference is, I don't think I'm allowed access to it. Ephemeronium (talk) 12:42, 4 August 2011 (UTC)[reply]

The third H on the N doesn't seem to be visible, and that detail is pretty important for what this diagram is illustrating. Maybe tilting the structure up a bit (so we can see more of the bottom of the amine?) might let us see the the back H peak out a bit? DMacks (talk) 15:12, 11 September 2011 (UTC)[reply]

It's on my to-do list now. Thanks for showing interest. Ephemeronium (talk) 13:39, 14 September 2011 (UTC)[reply]

Hi,

If you found another image using Comic sans, please add it to Category:Illustrations with Comic Sans text. It will allow to review if the use is justified and create derivative version if needed. --Dereckson (talk) 10:42, 13 August 2012 (UTC)[reply]

Hi, Jynto: I have improved the article "Cyclododecan" in the German WP. To illustrate the structure of this molecule, I browsed in COMMONS and found your grafics. However, I'am not shure about the origin of your pictures, i.e. the drawing program. Are the drawings in agreement with the original experimental results (see my sources given in German WP Cyclododecan)? Best regards --Durfo (talk) 09:48, 5 November 2012 (UTC)[reply]

(talk page stalker) Direct link is de:Cyclododecan, and I assume the images in question are File:Cyclododecane 3D ball.png and File:Cyclododecane 3D spacefill.png, illustrating (based on just our one available perspectie) an all-staggered/gauche conformation in an all-convex ("regular dodecagon") ring shape. To my eye, these two images have something like a C6 axis. I wonder if this is another case like #Superphane-3D geometry data above? Durfo, your article edits mention that it is D4, and cite (1960). "The structures of the middle ring compounds III. The structure of the cyclododecane". Helvetica Chimica Acta 43: 18–35. DOI:10.1002/hlca.19600430104. The abstract only gives mentions "syn–skew", which is consistent with the images. I don't have access to the article itself to see the more specific structure factors--are there actual dihedral angles or coordinates that would allow building a model of the specific crystal structure? DMacks (talk) 22:16, 5 November 2012 (UTC)[reply]

"Click here to see the category of images by me" on your userpage points to your old username, but the cat was renamed when you were. DMacks (talk) 21:46, 5 November 2012 (UTC)[reply]

... and also File:Echinopsidine-3D-spacefill.png. Ed (Edgar181) 19:18, 9 January 2013 (UTC)[reply]

I think the fault is mine because you probably derived the structure from File:Echinopsidine.png, which I created with the same error, but have now fixed with File:Echinopsidine.svg. Ed (Edgar181) 19:20, 9 January 2013 (UTC)[reply]

Dear Wikimedians,

Wikimedia Commons is happy to announce that the 2012 Picture of the Year competition is now open. We're interested in your opinion as to which images qualify to be the Picture of the Year for 2012. Voting is open to established Wikimedia users who meet the following criteria:

1. Users must have an account, at any Wikimedia project, which was registered before Tue, 01 Jan 2013 00:00:00 +0000 [UTC].
2. This user account must have more than 75 edits on any single Wikimedia project before Tue, 01 Jan 2013 00:00:00 +0000 [UTC]. Please check your account eligibility at the POTY 2012 Contest Eligibility tool.
3. Users must vote with an account meeting the above requirements either on Commons or another SUL-related Wikimedia project (for other Wikimedia projects, the account must be attached to the user's Commons account through SUL).

Hundreds of images that have been rated Featured Pictures by the international Wikimedia Commons community in the past year are all entered in this competition. From professional animal and plant shots to breathtaking panoramas and skylines, restorations of historically relevant images, images portraying the world's best architecture, maps, emblems, diagrams created with the most modern technology, and impressive human portraits, Commons features pictures of all flavors.

For your convenience, we have sorted the images into topic categories. Two rounds of voting will be held: In the first round, you can vote for as many images as you like. The first round category winners and the top ten overall will then make it to the final. In the final round, when a limited number of images are left, you must decide on the one image that you want to become the Picture of the Year.

To see the candidate images just go to the POTY 2012 page on Wikimedia Commons

Wikimedia Commons celebrates our featured images of 2012 with this contest. Your votes decide the Picture of the Year, so remember to vote in the first round by January 30, 2013.

Thanks,
the Wikimedia Commons Picture of the Year committee

How do you upload molecules? Do you use a special program? 24.96.184.145 21:11, 30 November 2013 (UTC)[reply]

Good question. I use a program called [Discovery Studio Visualiser http://accelrys.com/products/discovery-studio/visualization-download.php]. There are better ones available, but DS Visualiser is my favourite. It's free as well. Ben Mills has an excellent tutorial for that piece of software, which can be found here. Oh, and if you want your molecules to look like mine, these are the lighting settings that I use. Jynto (talk) 12:37, 1 December 2013 (UTC)[reply]

I'm glad I'm not the only one who doesn't like those animated gifs. I'll try to replace as many as possible, but my first priority is still on articles that don't have any molecule yet. If you're having difficulty finding them, I suggest going to Special:ListFiles and typing the username of someone who created one of them. You'll find that there aren't that many molecule-makers on WP, and most of what you see comes from a few people. - Jynto (talk) 15:44, 27 February 2015 (UTC)[reply]

Hi Jynto, seeing some of your fantastic work on Wikipedia, I also downloaded DS Visualizer. I would love to use the exact same settings you use (atom colors, lighting etc.). Would you be willing to share them? Is there a way to export/import these settings?. Specifically, I couldn't figure out how to get the atoms to be rendered in different sizes :(. Also, your image uploads sport this awesome color code legend - is this manual effort or do you use some kind of tool/automation? The result of my attempts will show here: DEPBT. Zalumon (talk) 23:00, 1 March 2015 (UTC)[reply]

• 
  Materials
• 
  Lighting (used for most of my molecules)
• 
  Just the 'from xtal' ones
• 
  Graphics

First let me say I am flattered that you'd like to learn from me. Here then are some of the settings I use. Find them under Edit → Preferences... → Molecule Window. The materials part is fairly straightforward, except dragging the sliders is woefully imprecise, and I wish there was a better way of doing it. You may want to experiment with their effects before you choose a style you like. I myself was originally tying to copy Ben Mills' style, until I arrived on something similar but distinct from it.

I got my lighting very similar to how Ben does his. Light 1 is pure white (255,255,255) and light 4 is dark grey (31,31,31). You can't easily see the arrow, but I put Light 4 at the equivalent position to Light 1, only in the opposite corner. In the 'from xtal' images (the ones based on scientific data), I vary the lighting a bit, to visually distinguish them. Lights 2 and 3 are slightly further out from the centre than 1 and 4, and they are both a lighter grey (63,63,63).

The graphics settings are pretty straightforward, but make sure the quality is set to ultra-high if it isn't already. The light blue background is just a shortcut I use to for making the background transparent, since there are no atoms of that colour.

I'll show you the atom sizes and colours tomorrow. But just to answer your question about colour codes, it is pretty much a text file that I paste from.

See ya later.

Jynto (talk) 02:49, 2 March 2015 (UTC)[reply]

Alright, let's do atom colours. (To change them, go to Chemistry → Element Properties...) This is my periodic table of colours. It's modified slightly from the DS Visualizer defaults. I only changed the colours of all the p-block elements (groups 13 to 18) and hydrogen, making most of them slightly darker than the defaults (or in the case of carbon and nitrogen, a lot darker). For the sake of consistency, I also made fluorine yellow-green instead of the default blue, since all the other halogens are the same colour as their elemental forms. Other than that, I changed hydrogen from pure white to 240,240,240.

Carbon is 80,80,80; oxygen is 245,30,30; nitrogen is 60,80,250; sulfur is 250,235,0; phosphorus is 250,140,0; fluorine is 200,250,100; chlorine is 18,220,18; bromine is 180,40,20; iodine is 150,20,150; selenium is 235,180,0. That should be enough to get you started. The rest can be found using an eyedropper tool on the periodic table image. Everything aside from the p-block and hydrogen is left as its default colour.

The colour code that I paste into descriptions can be found in its entirety in the description of the linked image.

Now for the atom sizes. I do not suggest you stick with the default sizes, as those are all over the place. The defaults for selenium and arsenic are even smaller than hydrogen! Where possible, I go for the van der Waals radius. This property is not known for every element, but it is the closest we can get to measuring the 'size' of an atom as if it were a tangible object. My sources for the data are here and here. In cases where they disagree, the first source takes priority (hydrogen should be 1.2, not 1.1). The only exception is carbon - I made it 1.58, because 1.7 looked way too big.

For every element lacking data (most of the transition metals, all the lanthanides, all but one of the actinides), I just use 1.8 as the standard. You will of course have to set all of these manually.

Now when you are editing atom sizes and colours, please please please DO NOT click the cross button on the Element Properties window or leave it by pushing the escape key. There is a bug in DS Visualizer where doing this will cause you to lose your settings. Only use the Close button at the bottom.

These sizes will show when you use scaled ball-and-stick models. That's the second option on the right next to CPK. You may notice one problem immediately when you do this - the atoms now look too big and the bonds too thin. It's difficult enough to see double and triple bonds at the best of times.

So hit CTRL-D to change the molecule's display style. Make sure no atoms are selected otherwise the changes will apply only to those atoms. Type 0.35 in both of the bottom two boxes. This gives (in my opinion) a well-proportioned molecule that is easy to understand.

Unfortunately there's no way to set these as the default, so you'll need to do this every time you save or render a molecule. Once you get in the habit of doing it, it's simply matter of selecting one of those boxes and pressing DOT 3 5 TAB DOT 3 5 ENTER. Remember that any new atoms you add after this will default to the old scaling; this can sometimes be difficult to notice, so always get in the habit of doing this if saving or rendering as a scaled ball-and-stick model.

The sizes you have set will also apply to your CPK (space-filling) models, so it's doubly important to get them right. I strongly recommend you do a space-filling model at the same time as you do ball-and-stick ones, since it's very little extra effort, and it means that editors have both to choose from.

Any further questions, just ask.

Hi Jynto. I'd like to preface this by saying that I'm in no way a chemist, and my understanding of chemical diagrams is rudimentary to say the least. I am, however, an OTRS responder, and we've received an email regarding your image at File:(R)-Phenylephrine molecule ball.png, which is used on the Wikipedia article for the chemical. Apparently - and I'm quoting directly here - "the formula has a hydrogen atom in place of the methyl group on the nitrogen atom". I'm guessing you may have based this image on File:Phenylephrine.png, which also appears to be incorrect. An apparently accurate diagram of the model can be found here. Would it be at all possible for you to upload a new version of this file with the CH₃ molecule added? Many thanks, Yunshui (talk) 12:17, 30 April 2015 (UTC)[reply]

Fixed it! Thanks for pointing that out. Factual errors like these do slip in from time to time, but I usually spot them myself. Turns out I'd managed to miss the error in all four versions of that molecule. Anyway, they're all fixed now. - Jynto (talk) 12:50, 30 April 2015 (UTC)[reply]

Here they are. And sorry for the delayed response. I too have things going on in real life. Because of time constraints I speed up my molecule making by batch-processing them. Some of these (as you can see by the dates) already happened to be in the 'production line' when you requested them. If you need any in the future for reasons besides general wiki improvements, don't be afraid to ask. Otherwise I'd just add them to the back of the queue, but you'll see them eventually. - Jynto (talk) 20:33, 31 May 2015 (UTC)[reply]

Looking in Category:Biphenyls, I see that there quite a few more that have the same issue. Ed (Edgar181) 20:50, 16 February 2016 (UTC)[reply]

Apologies for not getting back to you on this sooner. My reasons for doing this are two-fold. First, I use DS Visualizer to energy-minimise most of my molecules. This is usually accurate, it tends to prefer planar structures, but it will often build a molecule resembling the crystallographic data, if there is any. And it just so happens to make biphenyl rings coplanar (though there are exceptions, 2,2'-bis(2-indenyl)-biphenyl for instance). If I thought this was incorrect, I'd have to make an exception to the way I do things, just for that type of molecule.

Furthermore, both studies I found for biphenyl seem to show it as a fully coplanar molecule (J. Trotter, 1961 and Charbonneau & Delugeard, 1977). Are we to suggest that these crystal structures are wrong? If so, can you find me a crystallographic study that suggests otherwise? Then I will gladly incorporate it into my workflow.

Thanks

- Jynto (talk) 06:24, 24 February 2016 (UTC)[reply]

Hi chaps. Here's the crystal structure of 4,4′-biphenol: Jackisch et al., Acta Cryst. 1990 C46, 919-922, CSD refcode DOHDPH02. While 4,4′-biphenol is planar in this crystal structure, there are co-crystals in which it is twisted, such as NISLOQ. It might be worth showing both conformations in the WP article, and adding a very short commentary with references. I also found the structure of 2-phenylphenol: FIFMAI01. Although there is disorder in the structure, you can see the angle between the planes of the benzene rings is 57°. Jynto, could you update your image of 2-phenylphenol accordingly? --Ben (talk) 10:44, 15 March 2016 (UTC)[reply]

Thanks Ben. I've been busy lately, but I should be able to do it this weekend. Fingers crossed, and I should have them all done and updated on the same day. - Jynto (talk) 00:11, 24 March 2016 (UTC)[reply]
