Ammonia

Useful - and eclectic! - info on ammonia you posted. I encourage you to introduce that material into the article, perhaps in bits. It does not need to be perfect or polished - let someone else do that. I hope you continue with this project. --Smokefoot 12:12, 14 October 2007 (UTC)[reply]

electoless nickel plating

looking for references that give recipes and some idea of the chemistry thanksCinnamon colbert (talk) 21:17, 14 November 2008 (UTC)[reply]

Bismuth

Thanks for corrections. Please continue, but. Note that some edits get trashed blindly, only because they are unreferenced. If you add a WP:RS reference to your writing, it would be of great help. Don't hesitate to ask about mundane issues (formatting, etc.) - always glad to help. Materialscientist (talk) 00:36, 1 November 2009 (UTC)[reply]

Molecular Nitrogen bond strength implied weak in this article

Molecular Nitrogen is quite inert. Li,Mg Reactions to the contrary. More important to the average person is NOx formation during (high temp, pressure) adiabatic combustion phase of internal combustion engines. (Why no mention of historic Nitrogen fixation via Cyanamide? (CaCO3 + C + N2 > CaNCN)). Even Argon can displace N2 adsorbed to transition metal surfaces!

Need to mention the strength (bond energy) of N2 triple bond as driving force for many reactions. Orbital sp-sp bonds are an important class (CN-, NO+, et al) for 2nd row elements. Strength of NN bonds show in Molecular Nitrogen (NN+) discharge lasers (Aurora Borealis glow)), Nitrous Oxide, Diazonium compounds, Diazomethane reactions,

High energy of creation for NN triple bond drives NASA thrusters (from Rocket Research Company; NH2NH2 > Iridium Catalyst > N2 + 2 H2). Know that 2 H > H2 is 104 Kcal/mole; what is 2 N > N2 delta E? Shjacks45 (talk) 20:15, 9 May 2010 (UTC)[reply]

Did you not read the second paragraph in the lede/lead? This point is also emphasized in the section that deals with nitrogen use in fuels and explosives. I think a few of your other points are not in the article, but feel free to add them in the appropriate places. However, I urge you to READ it carefully first!

Peroxide

Again, thanks for expanding inorganic reactions, but please do provide references where you can - formatting we can handle. Also note that by default, contrary to some other sources, wikipedia tends to not capitalize words (chemicals, etc). Materialscientist (talk) 11:01, 16 April 2011 (UTC)[reply]

Making correction of nonsense

"the borax component of fiberglass insulation. " is nonsense. Owens-Corning makes Borosilicate glass which it trademarked as Pyrex, with superior strength and breakage resistace (thermal shock resistance) than ordinary soda lime glass. No reference specifically to borosilicate and fiberglass except both are Corning products. See Fiberglass and http://en.wikipedia.org/wiki/Fiberglass_batt#Fiberglass_batts_and_blankets Shjacks45 (talk) 05:41, 21 February 2014 (UTC)[reply]

Turns out this is complicated, and only the idea that borosilicate glass is in fiberglass is nonsense. But the article doesn't say that. Most boron use world-wide is indeed now used in glass fiber and both insulating and structural fiberglass, but not all fiberglass uses boron-containing glass fibers. Worldwide, it appears that most of it does, however, as it is especially popular in Asia. Boron is added to glass fibers for fiberglass as a fluxing agent, as borax hydrate or (different) boron oxide. It's not nonsense. The glass in fiberglass does not have to be the borosilicate glass used by Corning in Pyrex, or by other glass companies for glassware. That is a different glass. Most of boronated glass fiber is simply high-boron glass where the boron compounds are added as fluxing agents. [1] [2] About 10% of global boron compounds are used to make borosilicate glass for as glassware. Ceramics add being 15%, agriculture 11%, detergents/whiteners 6% and other uses the rest. I'll update the article, and provide refs. S B H arris 01:56, 15 August 2014 (UTC)[reply]

Flux is usually low melting compound that assist connection to solid surface, and generally not incorporated in product. So your saying Lead Oxide is a flux for lead glass because it melts lower? At 10% the mole fraction seems too high to be incindental incorporation of flux into product. Shjacks45 (talk) 22:57, 22 February 2020 (UTC)[reply]

Use your photos

Regarding your mention of photomicrographs on Talk:Ductile Iron, if you do not mention your former employer in the caption, you should be able to use them if you took them.

Did you ever work on your lunch hour or past your payroll quitting time? Then the principle that they are company property because they were made on company time does not necessarily apply- the work of preparation etc is owned by the company and they own a work-for-hire copyright on the photos they wanted, but if you chose to make extra photos on your own time (or time you were owed) the copyright on that work is yours.

It is a little more complicated if the company had a "no photos" policy in writing for visitors, office parties, take-your-daughter-to-work-day. But also, if you were ever instructed, or it was common practice, to throw extra copies, drafts of reports, or old files out in the trash without being shredded, then those things are yours to keep and you are their current owner. Remember though, that just because you own something does not mean you necessarily own the copyright for publication, or the right to disclose confidential information, (that is, information you agreed not to disclose about clients or methods) the work might contain. But it is usually easy to remove such confidential information when using the work for a general scientific purpose.

Thus photos you own, and that you took on time that was owed to you, can be considered "own work" even if they are similar to copyrighted works in the company's files.

Hope to see some of them!209.86.76.36 (talk) 23:54, 15 July 2015 (UTC)[reply]
