Oxidation States in Elements

What determines the oxidation state in a transition Metal when combined
with a compound? (Ie something like Iron or Copper that has 2 Oxidation
states) For example, If I combined Iron with Oxygen, what would
determine if I get FeO or Fe2O3? What Oxidation State do noble Metals
exsist in (like Copper Wire, What oxidation state does it have in pure
form?+1 or +2?)

No :-(  Not a single flake, and some of the lawns are still green.

Do you guys have all the same winter Xmas songs that we do, like "Sleigh
Ride" & "I’m Dreaming of a White Christmas"?  I’m so sick of the stupid Xmas
songs in all the stores & malls – next year I’m getting my shopping done
early!

Porous graphite for electrodes

I am looking for a source of porous graphite such as could be
used as non-reactive electrodes in saline solutions. I need the
very large surface to volume ration that porous or fibrous carbon
could provide. There is no need for high electrical conductivity,
but I do need the large surface area that such material should
provide.

I’ve searched for material of this type but all I’ve found is
graphite yarn, and it doesn’t seem to have continuous or reliable
electrical conductivity.  I would certainly appreciate some leads
on this.  Gordon

hydrogen: im- or ex-plosion?

When you invert an empty test tube over one containing zinc and HCl
and half a minute later move the inverted one over a bunsen flame you
get a healthy POP.

Do you reckon that sound is caused predominately by an IMplosion or by
an EXplosion?

Second question: what would be an easy way to demonstrate your answer
convincingly? (In a preferably non-destructive way.)

Merry Christmas to All on sci.chem

qPCR 2007 Press Release

qPCR 2007 Press Release

———————————————

http://qPCR2007.gene-quantification.info

Main sessions:   single-cell qPCR  &  microRNA / siRNA applications in
real-time RT-PCR

———————————————

The qPCR 2007 Event is organized jointly by Chair of Physiology,
Technical University of Munich (TUM)  and  TUM-Tech GmbH, Munich,
Germany

http://qPCR2007.gene-quantification.info

The Physiology Weihenstephan at the Technical University of Munich with
support from TUM-Tech GmbH is organizing the 3rd international qPCR
2007 Event taking place March 26 – 30 2007 in Freising Weihenstephan,
Germany. Scientists from all around the world will come to exchange
ideas, share experiences, and discuss the exciting future of the
perhaps most powerful analytical technology ever developed in the life
sciences area – the quantitative real-time polymerase chain reaction
(qPCR). More than 40 invited international speakers will present their
latest research findings in the qPCR field. Focus of the event will be
on single-cell qPCR technologies and microRNA/siRNA applications.

In connection with the symposium three practical qPCR Workshops will be
held March 29 – 30, 2007 by the TATAA Biocenter (www.tataa.com) – the
leading qPCR service provider in Europe. The 2-day workshops are hosted
by international renowned scientists and experts in the field. The
workshop themes will be:  (1) Classical qPCR Application Workshop;  (2)
qPCR Biostatistics & Expression Profiling;  (3) Sample Preparation &
Immuno-qPCR.

An Industrial Exhibition will take place parallel to the symposium,
with 30 leading biotechnology companies presenting their latest
developments in the PCR field, including real-time PCR cyclers, nucleic
acid extraction robots, consumables, fluorescence dyes, DNA and RNA
detection and amplification chemistries, as well as real-time PCR data
analysis software.

qPCR, is an improved form of the PCR technology that was awarded the
1993 years Nobel price in Chemistry. Using qPCR the amount of target
nucleic acid in a complex sample can be determined with high precision,
great accuracy, excellent specificity and the ultimate sensitivity of
detecting a single molecule. The technique has revolutionized all
molecular sciences and diagnostic applications. Conference
presentations will include high throughput applications, improved
instrumentation, high performance nucleic acid extraction, immuno-qPCR
applications, single-cell applications, and application involving
siRNAs/miRNAs. Further developments of qPCR technology that will be
presented include miniaturization, high throughput platforms, cost
efficacy, validity, flexibility, quality assessment and reliable data
calculations and interpretation. Today there is no field in the life
sciences research and diagnostics areas that has not introduced qPCR
technology for nucleic acid analysis. The combination with reverse
transcription enables determination of mRNA and widely opens the window
for "Transcriptomics" – the first step of gene expression and
"Functional Genomics".

The Physiology Weihenstephan at the Center of Life and Food Sciences at
Technical University of Munich, chaired by Prof. Heinrich H. D. Meyer,
is a leading authority in the molecular physiology of mammalian
species. Cutting edge biochemical and molecular biology techniques are
established for basic and applied research on the regulation of
reproduction, lactation, immunology, and growth. Both traditional
endocrinology and paracrine regulations are studied in numerous
tissues. Dr. Michael W. Pfaffl is developing qRT-PCR methods, software
algorithms and tools for quantitative gene expression analysis. He also
maintains the  leading qPCR information web page:
