recently
 there have been a few stories going around
 about researchers showing lithium ion batteries composed of silicon nanotubes
in which apparently they were able to get power densities 10x that of market lithium ion batteries

I realize that the molecule would not be polar persay, but the
flourine shell would carry a slight negative charge and should engage
in quite a bit of hydrogen bonding.

I'm curious about the a repeated manufacturers claim that negative
ions emitted by some air cleaners cause dust particles to clump out of
the air.
Anybody who as passed high school chemistry (which apparently already

"Aluminium burns now does it? Oh my god.

is there any way I could heat up methoxide inside an N2 pressurized
Parr reactor for several days in a SAFE manner? any advice would be
very much appreciated. Thanks!

I have a mixture of alcohols as below
C2 - 8%
C3 - 1% (Only normal)
C4 - 9% (n + iso both)

I'm told that there is a manual for the Milton Ron CM 4000 multiple solvent
delivery system available online in pdf form but I haven't succeeded in
locating it. Does anyone know where I can download it from?

Many chemistry texts refer to the zig-zag or stair step line on the
periodic table that separates metals from non-metals and go on to note
that metalloids (supposedly) lie along this line.
Does anybody know who who first came up with the idea of this so-

What Is Cancer?
Cancer is actually a group of many related diseases that all have to
do with cells. Cells are the very small units that make up all living
things, including the human body. There are billions of cells in each

forum for this type of question.
So, a long time ago (in this same galaxy, no far away at all) I was

How do detonators work?
From wikipedia: A detonator is a device used to trigger an explosive
device.
Detonators can be chemically, mechanically, or electrically initiated,

I've used up a very old bottle of a dyestuff for which I know the
structure and CAS#,  but when I contact vendors, they want a trivial
name and/or the Color Index number, which I do not have.   Is there
listing somewhere that I can go to to look up this compound by CAS#,

What is the molecular formula of diesel in general?
Is biodiesel similiar to the conventional diesel in chemical
composition?
