issue of 'Teamwork' includes:
- A reminder
about the next funding round
- A report on
the Division Officers' meeting at the IUPAC Secretariat in December.
- Changes to
the Division V web pages.
- 'Profiles'
for members of the Division Committee: Kazuko Matsumoto
(TM; Japan) and Marja-Liisa Riekkola (NR; Finland).

The next funding
round
For the Project submission form, guidelines for its completion and
an example of a completed submission form, see: www.iupac.org/divisions/V/projects/index.html
The next funding
round will be based on complete Project proposals received up to
April 1, 2003. To date we have received rather few proposals
for this next round, but now is the time to put the finishing touches
to your proposal! TM, please consult with your Advisor groups and
potential Task groups about this deadline.
Division Officer's
meeting
David Moore, Folke Ingman, Kip Powell and Ryszard Lobinski met at
the IUPAC Secretariat, November 30 - December 1.
The meeting
-
advanced
the process to improve the quality of information about Division
activities (e.g. via the web pages).
-
constituted
the Nominating Committee for the next Division Committee elections.
-
reviewed
the progress of all current Projects.
-
made
strategic decisions about the use of future Division meetings
to
-
assist
in building bridges with the wider scientific community,
-
hearing
their perception of needs for IUPAC initiatives,
-
engaging
the Division members in a 'think tank' exercise with the aim
of developing new projects.
Division web pages
The example of a completed Project
Submission form has been updated to provide more explicit 'explanatory
notes'. Flow diagrams have been developed to provide Division members
and Task Group members with a clear indication of the stage and
status of each 'final' project document after it has been submitted
for review.
There are many
steps in the review process, involving internal and external referees,
assessment (at each stage) by the ICTNS (Inter-Divisional Committee
on Terminology, Nomenclature and Symbols) and, in the case of 'IUPAC
Recommendations', a period of 'public review' via the web.
As we go to
press these changes are in the hands of the Secretariat but have
not yet appeared as modified web pages.
Nominating Committee
The Nominating Committee has been constituted as Folke Ingman (chair,
Sweden), Freddy Adams (Belgium), Bob Byrne (U.S.A.), Bob Cattrall
(Australia) and Adam Hulanicki (Poland). The Secretariat has already
invited all NAO's to submit nominations for positions on all of
the Division and Standing Committees (closing date January 15).
The Division President invites all Division Committee members and
Task Group members to contribute further nominations. The closing
date for these is February 15:
If
you know of colleagues or other analytical chemists (or related
disciplines), who would be willing to take on the task of furthering
the work of the IUPAC and especially the Analytical Chemistry Division,
please contact them regarding their willingness to work in that
capacity (have them consult the Division web pages http://www.iupac.org/divisions/V
for further information or clarification of what it is we actually
do!) Then, if they are willing to be considered as a nominee, please
obtain the following items from them and forward them to the Nominating
Committee Chair, Folke Ingman ([email protected]):
1/2 page resume (CV) and 1/2 page explanation of how they would
further the work of the division and the IUPAC if elected.
It is important that the Division Committee (NR + AM + TM) be constituted
to provide geographic balance, include experienced scientists and
emerging experts, provide subject balance, and meet the needs of
both 'core' and 'emerging' areas of analytical chemistry.
Elections.
Since the Division meeting there has been an e-mail ballot to elect
the Division officers for 2004-5. This resulted in Roger Smith being
elected as Secretary and Ryszard Lobinski being elected as Vice-President.
David Moore moves to Past-President and Kip Powell moves to President.
This process had to precede the work of the Nominating Committee
so that the number of 'vacant' positions on the Division Committee
could be defined.
Learning from our
Stakeholders
Starting with the combined Division Officer's/ Commission chair's
meeting in Idstein in January 1998, the Division has been trying
to improve its links with stakeholders/end-users. This process has
been only partially successful, but does occur through Conference
presentations of IUPAC projects, the requirement that stakeholders/end-users
are involved in Task Groups for all new applications for Project
funds, and through improved dissemination plans (e.g. 'announcements'
in key analytical chemistry journals). The Idstein, and subsequent
meetings, also identified the need for targeted 'workshops' which
brought key industry sectors (e.g. pharmaceutical) and appropriate
members of the Division Committee together. Such meetings have not
yet occurred.
The Division
Officer's meeting in 2002 also noted the capacity for the Division
Committee to be much more pro-active in identifying projects. That
is, the Committee meetings could, in part, assume the role of a
'think tank' and so generate Project proposals 'from the top down'
(the inverse of the present process).
Thus, the Division
Officers are proceeding with a plan to include a Workshop as part
of the biennial meeting in Ottawa, at which
-
Key
participants from the IUPAC Congress will be invited to present
their views on current needs and trends in analytical chemistry
-
Division
members will be invited to make similar contributions relevant
to their area of expertise.
-
The
views of each group of presenters will be discussed.
-
Project
priorities will be identified.
This is an
exciting new development and may well impact on the future focus
of Division Committee business.
Project Reports
Thank you to all those who submitted progress reports! The 5 months
since the previous reporting period have been very productive! Two
projects have been completed, two have progressed as far as review
by the ICTNS and one has been submitted for external review.
Spreading
the word
Did you know that the December issue of Chemistry
International contained 6 articles related to activities
of the Analytical Chemistry Division! There is one more article
in the January-February issue. Well done! We are very keen to see
'an article for CI' as one component of every dissemination
plan for Division V projects.
Division
Profiles
In this issue of Teamwork we introduce two female members
of the Division Committee to our readers. Kazuko Matsumoto
is a TM representing Japan. Marja-Liisa Riekkola is
a NR, representing Finland and was previously a member of the Commission
on Separation Methods in Analytical Chemistry (1996-2001),
Kazuko Matsumoto was born in Tokyo. She received her B.S.(1972),
M.S. (1974), and PhD (1977) from The University of Tokyo. In 1977-1984,
she worked in the group of Prof. K. Fuwa at The University of Tokyo
as a research associate. In 1984 she moved to Waseda University
as associate professor and was promoted to a full professor there
in 1989. During these years, she spent two years (1991-92) at the
Institute for Molecular Science (Japan) as an adjunct professor,
and spent half a year (1992) at MIT as a visiting professor. She
is now the vice president of the Japan Analytical Chemical Society,
and is also a member of The Council of Science and Technology Policy
of Japan.
Her research
area is related to analytical applications of metal-complexes as
follows:
(i) development
of new biotechnology using new lanthanide fluorescent chelate
labels for time-resolved fluorometry (immunoassay, DNA hybridization
assay, a multicolor labeling system, bioimaging, a biochip system)
The study includes the development of both labels and instruments,
i.e., lanthanide-chelate labels which can be covalently bound
to proteins and nucleic acids, and time-resolved fluorometric
instruments based on the new concept for a multicolor labelling
and detection system. The combination of the lanthanide labels
and time-resolved fluorometry has turned out to efficiently remove
the background fluorescence and improve the detection limits of
conventional methods by 2 to 4 orders of magnitude. The principle
is expanded to many bioassay systems.
(ii) one-dimensional
nano-wire metal complexes having delocalized metal-metal bonds
with new luminescence and electronic properties.

Conference Report
One way to discern the needs of end-users is to discuss the Objectives
of your IUPAC Project Proposal at an appropriate Conference.
Yoshio Umezawa
(chair) and Erno Lindner are members of the Task Group that
is preparing an IUPAC Technical Report on: "Performance evaluation
criteria for preparation and measurement of macro and microfabricated
ion-selective electrodes". They write about their IUPAC sponsored
participation in the Matrafured 02 Conference on Electrochemical
Sensors:
The focus
of the conference was related to recent developments in the field
of ion-selective electrodes. In specific discussion sessions,
several of the targeted topics of the proposed Technical Report
were discussed in detail. In these discussions it was generally
accepted that, based on the developments in the understanding
of the response mechanism of ion-selective electrodes, some of
the previous IUPAC recommendations have to be revisited. In addition,
it was recognised that issues related to the reported extraordinarily
low detection limits of certain ion-selective electrodes should
be incorporated into a new document. Also, it was concluded that
the problems associated with miniaturisation of ion-selective
electrodes should be addressed. In summary, these discussions
confirmed the importance and timeliness of the project.
In the discussion
sessions of the conference, several areas of interest, which were
not specifically mentioned in the original proposal, were also
discussed. These included but were not restricted to problems
of the:
-
use
of non-equilibrium devices in potentiometry
-
potentiometric
sensors with twice-Nernstian or half-Nernstian responses
-
definition
of the detection limit of potentiometric sensors with super-Nernstian
response in extremely low concentrations.
-
recommended
procedures for determining the selectivity coefficients of potentiometric
sensors.
-
recommended
calibration procedures before potentiometric measurements in
biological samples such as whole blood, serum or plasma.
In the first
draft of the technical report these additional issues will be addressed.
They also note
that:
According
to the original proposal, the Technical report should give guidelines
for the performance evaluation criteria of micro reference electrodes.
The importance of the reference electrode and liquid junction potentials
in potentiometry can not be over-emphasised. The design of high
stability micro reference electrodes for monitoring acute and chronic
illness is especially challenging. Unfortunately, only a very limited
number of reports discuss these difficulties. Due to the lack of
information in this important area the performance evaluation criteria
can not fully be discussed in the desirable depth in the Technical
report.
Erno also writes
that most of the conference participants did not recognise the significant
difference between IUPAC 'Recommendations' and IUPAC
'Technical Report'. Most had the impression that any
document published in PAC with an IUPAC heading represented the
'official' stand of IUPAC. In fact this only applies to 'Recommendations'.
Teamwork
could be the vehicle for you to share concerns or interesting news
items. Do let me have your contributions!
