P Cottontail,

I am looking to hire a polyurethane expert. If interested, please email

Thanks, Dan

RE: Graphics Lab SVG[edit]

I had a look at the SVG code of your image, and all it contains is an image (the .PNG) imported into the SVG. This isn't how SVGs are made: you need to re-make the image as a series of shapes, or, for this image, text. I had a look at the the PNG image, and it is at a high resolution, but if you still want an SVG, submit a request to the Images to Improve Page, and I or someone else will make an SVG. --Dave the Rave (DTR)talk 11:17, 19 August 2007 (UTC)

Dave: Thanks for getting back to me on this. Makes perfect sense. Does Inkscape convert any other format directly to .svg, such as .bmp, or does every image have to be redrawn (seems tedious)? Is it worth converting high resolution .png's to .svg's? Can/should I remove the "...please convert this to .svg..." tag from the high resolution .png's, and comment that they are already at high res? Best Regards, P Cottontail 14:28, 19 August 2007 (UTC)
.PNG, .BMP, .JPG, .GIF, .TIF and others are Raster images that store the image as a series of dots (pixels). Vector images store the instructions to make the image as series of shapes. The images contain different data, so you can't convert from a raster image to a vector image just like that. What Inkscape (and other vector packages) is give you the tools to define these shapes.
Inkscape does have a function called Trace Bitmap which attempts to trace shapes around the image, but this works best on simple things, like line drawings. My opinion is that the image is at a high enough res to keep it a raster image, but I can still convert to SVG if you want (Wikiproject Chemistry might have something to say). --Dave the Rave (DTR)talk 15:12, 19 August 2007 (UTC)
Okay. I guess I'll have to read the Inkscape tutorial and try some of these reaction equations and structures as .svg's. I'll post over at the Wikiproject Chemistry to get their take on the .png/.svg choice. If they'd like .svg's. I'll get back to you. And, thanks for making the offer in the first place. Cheers, P Cottontail 15:22, 19 August 2007 (UTC)
That's okay. --Dave the Rave (DTR)talk 15:26, 19 August 2007 (UTC)

CPI conference[edit]

P Cottontail, are you attending the CPI conference in Orlando this month?Silverchemist 14:30, 15 September 2007 (UTC)

Hello, Silverchemist: Unfortunately, no. I am too far down on the food chain (by choice) to go. Just the GM and Tech Director go. Now, if/when they decide to do it in London/Amsterdam, I'd probably whinge loud enough in order to make the trip! Are you going? Best Regards, P Cottontail 15:15, 15 September 2007 (UTC)
Yes, I just booked my flights. I'll be busy: authored two papers, presenting one on natural oil polyols, moderating an automotive session and organized three sessions. And some people think conferences are just for fun!
Keep up the good work on the Polyurethanes article. I'll help when I can.Silverchemist 16:08, 15 September 2007 (UTC)
I hope you have a good conference, and your presentation and moderator gigs go well. Travel safe!
And thanks for the help on the PU article. The images of the MDI isomers are excellent and timely. Hopefully have it out of start class by the new year, yes? P Cottontail 21:33, 15 September 2007 (UTC)
The conference went very well. Approx. 1000 attended the technical part (85 papers, 15 posters) and another 1000 for the trade show. Natural oil polyols (NOP) were the hot topic (standing room only in technical sessions, >200 in th eaudience). My NOP paper was selected as best paper in that section. The other paper I wrote (too busy to do the presentation) was selected as best in the Automotive section. I couldn't ask for anything better than that.
Regarding this article, IMHO its well beyond start class, perhaps even FA is not too high a goal for the end of the year. Silverchemist 16:22, 28 September 2007 (UTC)

Upgrade Polyurethanes to higher rating[edit]

You are doing a fantastic job on the Polyurethanes article. I particularly liked your graph of applications as a function of density and foam type. I think the article should be a shoo-in for an upgrade in status. I'll look through it for any minor "wiki" edits. I've been concentrating more on the pulp and paper articles lately since they really needed attention and you are doing such a good job with this one. Let's use the Talk page on the PU article.
