Nonoxyl-what

I can't get the phrase "Nonoxyl-1,5-Triethylamine" out of my head. Obviously, it is an IUPAC name for an organic chemical, but AP Chemistry was a long time ago and I can't quite map out if it's valid— my hunch is "no." Is there a notable chemical that has a similar name that I might be half-remembering? More importantly, is there a website where I can look things like this up in the future?

How would the Horta actually work?

"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?

One-Trick Pony needs her trick back

There's a hair product my friends and I love that's been discontinued. Do you know of any companies or chemists that can duplicate it using the ingredients list on the back of the container for a reasonable price? Is there a minimum volume? Can I sell the extra on Ebay? Is this possible or just a pipe dream?

How important are (chemistry) graduate school rankings?

I am planning to go get my PhD in chemistry and I am waiting to hear back from schools. I have already been accepted to 3 schools (one in the top 10), however, I really like some of the faculty at one located in the 30s in the rankings. How important are the rankings and will they have a big affect on my career?

Chocolate Chip Cookie Chemistry

I'm baking chocolate chip cookies and after looking at some recipes, I realized that they all use baking soda (not baking powder) as the leavening agent. The explanation is that baking soda interacts with the acids in the chocolate to produce the leavening CO2. My question is this: Can I freeze my baking soda leavened dough? Can I leave it in the fridge until I'm ready to bake? [more inside]

What is that strange acrid smell whle showering

My shower (an in-stall water heater) sometimes smells like something rubber is burning. It's a strong acrid smell that I only notice while in the shower and usually only after a sweaty workout. There is no sign of smoke like you would expect with burning rubber. Is this just some sort of weird sweat and treated water chemical reaction? Anybody heard of something like this?
