What can this material be used as?31 Jul 2009 15:52 GMT2
We synthesized a carbon supported platinum catalyst for fuel cell.
Occasionally, we found that this catalyst can catalyse Hydrogen and
ethanol to burn in room temperature. Now we are very curious which
field this property of the catalyst can be applied? If someone feels
Solubility of silica in molten sodium tungstate29 Jul 2009 02:33 GMT1
In a now classical study of the polymorphism of silica  in 1913 Fenner
used molten sodium tungstate, Na2WO4, as a solvent for silica, but he
did not report how much silica can be dissolved  at various
tempertures. It might be only a few percent at 1000C.

Glue in a Microwave Oven18 Jul 2009 19:08 GMT3
The plastic support for the turntable in my microwave oven
broke into two pieces.  I'd like to glue it back together,
which I think should be easy enough to do, but I'm not sure
what glue to use that will hold up to the heat and moisture
vacuum pump for liquids16 Jul 2009 19:17 GMT4
Are there vacuum pumps that are made for distilling liquids without the
need for cold traps, and that wouldn't contaminate or damage the pump?
Thanks.
Proof that for a particle with a non-zero rest mass, If v is small     enough compared to c then the relativistic kinetic energy of the particle can     be approximated to by the non relativistic kinetic energy of the particle16 Jul 2009 16:46 GMT1
The following relates to a particle with a non-zero rest mass i.e. a
“massive particle”.
E = mc^2
where: E is the total relativistic energy of a particle, m is the

Converting methane to electricity?06 Jul 2009 15:11 GMT8
Googling "Converting methane to electricity" returns results that burn
it and then use the kinetic energy of the gas to drive a prime mover
of an electricity generator. As someone who's a complete incompetent
in this area, I would have thought that most generators using this
