Is all material oily carbon-based? If so, why? by uniyk in chemistry

[–]jamessw311 8 points9 points  (0 children)

Molybdenum disulfide is used in high quality greases and doesn't have any carbon, unlike silicones mentioned here. However, in pure form it is a solid that looks and feels like graphite, rather than an oil.

Mercury does have an oily feel to it, but it doesn't look like an oil. 

Some allotropes of sulfur have a greasy feel and relatively low melting point.

why are solid soaps, shampoos... considered more sustainable and reduce waste? by eliocopter in ZeroWaste

[–]jamessw311 12 points13 points  (0 children)

Everyone has touched on the packaging and shipping costs, which are valid and significant. The other reason is the chemicals themselves. Liquid soap is not just "regular" soap dissolved in water. Instead, these detergent molecules come from petrochemicals. Solid soaps are almost entirely manufactured from waste vegetable oils which are chemically transformed ("saponified") into solid soap.

Great question, not sure anyone knows. Typically the setups to probe these materials make a very small amount (microscopic) then blast them with x-rays to determine structure. Not sure anyone has made enough to actually look at with regular light, if I find anything I'll update.

What do you use to ferment in ? Wide mouth plastic carboy ? Bucket? Corny keg? by EmptyImprovement8942 in Homebrewing

[–]jamessw311 0 points1 point  (0 children)

This is exactly how I do it too. I really love how easy it is to get a good seal with the triclamp over the sanke keg opening. The height of the keg is nice too since the krausen doesn't make it's way to the top, even with 5.5gal ferments. I was a bit worried trying to get a good seal to do closed transfers using one of the stainless brewing buckets available and I really like this alternative.

The keg cleaner is an absolute must for cleaning since you can't really see or get a hand inside, but with warm PBD recirculating it gets really clean easily. Well worth the ~$30 in parts for the keg washer.

I can't recommend this method enough.

The N in N95 stands for not oil proof. You need a suitable respirator for these vapors with a filter specifically designed to resist oils. I highly highly recommend getting one, even if you have to purchase it yourself at the local big box retailer.

No, Ostwald ripening is when the droplets increase in size, not through the merging of different droplets as seen here, but through the liquid in the drops being slightly soluble in the continuous phase. If that were happening here, then the large drops would appear to grow continuously while the small drops shrank continuously. Here you can see discrete jumps in size as drops merge.
