It's still winter in Pennsylvania and we're all
huddled around hot soldering irons, computers, and
potentiostats, trying to stay warm.

Rusty is Gamry's Mascot and official "Party
Animal."
He wishes you and yours the Very Best in the
upcoming year!

| What does Planck's constant have to do with Us? |
|
So far, we have been able to get by with remembering
just a few fundamental constants: The Faraday
(96,485 C/mol), RT/F (59.2 mV/decade @25 °C),
Avogadro's number (6.02x1023
mol-1), and maybe one or two more.
Now we may have to remember Planck's constant
(h=6.63x10-34 J-s)!

Who uses Gamry Potentiostats?
We'd like to think that every Electrochemist uses a
Gamry Potentiostat in their research. Maybe it's
just our pride talking, but we know that everyone should use them!
You might be interested in seeing what kind of
research has been done using Gamry Potentiostats.
We've compiled a list of literature citations where a Gamry Potentiostat has been used. If your paper isn't on the
list, send us a reprint. We'll add it to the list!

| Part 3 of EIS for Coatings is Available! |
|
In the last issue, we announced that Parts 1 and 2
of "Evaluation of Organic Coatings with
Electrochemical Impedance Spectroscopy" had been
published in JCT CoatingsTech." Well, the
final article in the series, "Protocols for Testing
Coatings with EIS" appeared in the February issue!
Go to your library, or click the tiny image, above,
and check out the picture on the cover! Two
technicians and a Gamry Potentiostat are perched
atop a very BIG airplane, making Impedance measurements!

| Short Courses Fill Quickly! |
|
It's time to start planning your Spring and Summer!
Gamry helps to sponsor two Electrochemistry Short
Courses, one on EIS in May, and another on Corrosion
in July. Our feedback says they are both great
learning experiences, and fill up quickly!
The courses are organized and taught by recognized
experts in their fields. Both courses feature a
hands-on laboratory that really brings the lessons
home. Gamry staff will be there to answer questions.

| Stop by and say "Howdy Partner!" |
|
NACE's "Corrosion 2005" is in Houston this year.
Stop by and say "Howdy!" If you miss us in Houston,
check the list of conferences and exhibitions where
you can meet with Gamry staff or your Gamry
representative!

| Free Tutorial @ CORROSION/2005 |
|
|
NACE is sponsoring a Free tutrorial "Use of Electrochemical Techniques for Corrosion Measurement and Monitoring" in conjunction with
CORROSION/2005. Gamry's Dr. Pete Peterson will be speaking on Polarization Resistance!

What is a "Porous Bounded Warburg" and Why do I need it? |
|
|
|
Whenever you read about Electrochemical Impedance,
one of the first things they tell you is "The system
must be stable and unchanging." Normally that means
that you should run the EIS experiment at the Open
Circuit
Potential, where the DC current is zero.
Sometimes, though, you'd like to study the reaction
when there IS a net current. A very relevant example
is the study of catalysts for fuel cell electrodes.
Often you'd like to study the catalyst under
conditions very similar to that in an operating fuel
cell, where the current density is large.
The Rotated Disk
Electrode can come to the rescue! One of the nice
things about the RDE is that the DC,
diffusion controlled current is at Steady State, so
it meets the stability criterion of EIS!
