Does anyone know of an very elementary discussion and working
principles of echelle monochromator as a review article/ website as
how the order sorter works and how the spectrum is obtained in a two
dimensional way. I have a chemistry background, most websites are

Folks,
I've seen some references in the literature for functionalizing glass
surfaces with amine groups using Ethanolamine hydrochloride (instead
of using silanes). The rationale being that the polymerization of

Greetings.  I am an art student constructing a sculpture from various
glassware.  While scouring my University's campus for raw materials, I
came across two large brown glass bottles disposed of by our
biochemistry lab.  The bottles are empty, but labeled to contain

What should be difference in simulating flow of solid-water and solid-
gas flow through pipeline?

anyone knows what is the Silicat Garden?

Magnetite, mixed-valence ferrites in general, are supremely insoluble
in any non-reactive solvent.  Adding a jot of hydrazine to boiler
steam semi-reduces iron oxides and plates out magnetite inside pipes.
This passivates them against further corrosion.  The idea of

I have some elemental bismuth that I want to grow some crystals with
and may make some slugs for mag lev experiments. I need a relatively
cheap store bought item that I can safely melt (on the stove top) and
re-harden it in. Does molten bismuth attack stainless steel or

I am looking for a method of electroplating Strontium. I am trying to
use a platinum electrode to electroplate Strontium on to a stainless
steel disk. I have had good sucess electroplating the Actinides wiht a
solution consisting primarily of  ammonium oxalate and  ammonium

I need some info about concentrating h2o2 by vacuun distillation

I'm trying to find out if there is a process similar to etching
silicon with KOH to create a V shaped groove with a sidewall angle of
about 60 degrees in metal (aluminum, copper, steel, etc).
my gut feeling says no, but I'm hoping that there is :)

Does anyone know of a term used in chemistry (maybe molecular
geometry) to define the "main stemness" of
a molecule?
By "main stemness" I mean the following: I would imagine that some

Hi, we are a manufacturing cosmeceutical company that requires a 3
roll mill capable of taking volumes of product around 100 litres at
any one time. We currently have a small Exakt mill with a length of
roller 15cm which is way too small and slow and it breaks too often.

I'm pretty new to this very old system....
Is there any moderation in usenet groups, like sci.chem?
I saw some spamming "threads" (i don't know if you call em like that)
like "ChinesePingyao518" that only move down other important ones. If
