230/23/89 Terminology for Diffusion in the
Solid State
Kizilyalli
reported on a previously refereed draft manuscript, "Definition of
Terms for Diffusion in the Solid State", by M. Kizilyalli, J.
Corish, and R.
Metselaar. Corish and Chadwick volunteered to perform a final
review of the manuscript, with special care taken to ensure that the
symbols used are in agreement with IUPAC recommendations. They will
FTP the finalized manuscript to Rosenblatt by 12 July. Rosenblatt
will maintain it on a server for FTP downloading (LORENZO.WINS.LBL.Gov).
The referees will be informed by e-mail that a revised manuscript
is now available for their viewing. Each reviewer is being individually
contacted to preserve the confidentiality of their identities.

230/24/93 Chemical Research Needed to Improve
High-Temperature Processing of Advanced Ceramics
Kolar distributed a short progress report. Several suggestions
for improvement and additions to the draft manuscript distributed
at the Geneva meeting were received. Kolar will prepare an amended
version of the report and send it by e-mail to Spear
by 15 August. Spear will review and edit it before the 10 September
meeting of the Inorganic Division executive committee of Corish, Rosenblatt,
and Busch at Berkeley. Corish may use this draft to illustrate Commission
II.3 activity in the materials field at the Bureau Meeting in Frankfurt
on 26-27 September. In parallel, Kolar and coworkers will work further
on the document. The revised document will be sent to commission members
at the beginning of 1999 for comments and suggestions. An amended
manuscript will be reviewed at the Commission II.3 meeting in Berlin
in August 1999. The title of the report should be amended to read
"Chemical Research Needed to Improve High Temperature Processing of
Advanced Ceramic Materials".

230/27/95 Terminology of Vapor Deposition
Spear reported
that Carlsson
will share responsibility for managing the efforts of several experts
to provide more breadth to the project. Leskala
will oversee atomic layer epitaxy (ALE) terminology; Hastie will handle
laser ablation terminology, and Teer will collect terminology for
PVD processes. Chatillon
volunteered to provide names of experts for help with the MBE terminology
area. A draft report for review by the Commission is planned for the
Berlin IUPAC meeting.
SC-2 (232/1/91) Characterization of Carbonaceous
Materials and New Carbons
Boehm reported
that the compilation of various national standards for the characterization
of carbon materials is close to completion. Professor E. Heintz (U.
of Buffalo, NY, USA) will send the finalized manuscript in the near
future, and Boehm will forward it to the other members of SC-2 for
comment without delay.

PST-18 Calculation of Equilibrium Thermodynamic
Properties of High-Temperature Superconductors
Voronin submitted
an extensive report entitled "Thermodynamics of High-Temperature Superconductors
in Yttrium-Barium-Copper-Oxygen System, Part 1: Y-123 Solid Solution",
which includes an analysis of results of experimental and theoretical
investigations. About 3000 experimental results obtained in 220 miscellaneous
experiments published in 57 papers have been processed simultaneously
to obtain the most reliable Gibbs energy of the Y-123 solid solution
in the temperature region from 250 K to 1300 K. A linear error model
was employed for the simultaneous assessment and compared with results
of the conventional weighted least squares method. The benefit of
the new approach is emphasized. Voronin estimates that the project
may be finished within 1.5 years.
In the discussion, the necessity was pointed out to distinguish between
original scientific contributions and IUPAC commission reviews. Some
of the results mentioned above have been previously published. It
was concluded that the final IUPAC commission report should be edited
and compared to the distributed document, by referencing previously
published articles that describe experimental and calculated procedures
and results. The commission report to be published in Pure and Applied
Chemistry (PAC) should summarize conclusions developed from the review
and analysis of the global body of work performed, and should explain
the scientific and technological importance of the unique data analysis.
The value of publication in PAC will be to inform interested readers
about the existence of the collected data and a new tool for their
interpretation.
Voronin will prepare a modified commission-sponsored article for
PAC that summarizes conclusions and applications while referencing
available journal articles that contain the original data and the
full details of the analysis technique.

PST-16 Teaching of High-Temperature Materials
Chemistry at Universities
Commission regrets that because of a recent accident, Balducci
was neither able to attend the meeting nor to prepare an extensive
report. However, Balducci informed the chairman that he would submit
a report to commission members by the end of summer 1998.

WB-3 Structure and Properties of Ceramic Fibers
Lewis was not
present to report, owing to the examination schedule at Warwick University.
In a short written report, he informed the commission that there are
new developments in the field but the progress is slow in relation
to commercially available fibers. If the period as a watching brief
(WB) is soon to expire, Lewis would be prepared to initiate a task
force (TF); however, it is not clear that a survey, defining structure
and properties, is within the meaning of an IUPAC TF. Commission members
believe the project is timely and justified. It is necessary to find
experts willing to help in the further definition and carrying out
of the project. Lewis mentioned that he needs to reconsider his continued
participation in IUPAC projects. Spear
will contact Lewis to clarify this matter.

230/9/83 High-Temperature Mass Spectrometry
Ionization Cross-Sections
Chatillon's
report contains 3 sections (metals, ionization cross-sections, and
thermodynamics), including 40 pages of text, 140 references, and a
limited number of tables and figures. Data on the cross-sections proposed
by Man are being considered for inclusion as an Appendix. Chatillon
will convey the document to Drowart,
who will complete the tables for this project during June/July. Chatillon
will prepare a new draft report, which will be given to "mass spectrometry"
experts before the Gordon Research Conference (GRC) on "High Temperature
Materials: Processing and Diagnostics" in Plymouth, New Hampshire
on 19-24 July 1998. Chatillon will not attend the conference, but
Drowart and Hastie will coordinate discussions with experts at this
GRC. Suggestions will be recorded and communicated to Chatillon. Chatillon
and Drowart will complete the document in September. The final document,
reviewed by Spear,
Rosenblatt,
and Corish,
will be ready for review by the commission at the IUPAC meeting in
Berlin in August 1999.

230/25/93 Surface Analysis of Ceramics
Lewis was not
present to report. In a written report, he informed the commission
that the two other contributors to this project (Dowsett and Watts)
have made no further progress owing to pressure of teaching and research.
Prospects for completion before the 1999 meeting are poor. Spear
will contact Lewis to clarify further prospects for this project.

230/29/95 Teaching Experiments in Solid
State Chemistry
Kizilyalli's
report includes a list of 21 experiments developed and edited by various
authors. The initial two sets of experiments, edited by Kihlborg and
presented at the Guildford meeting, were developed at Stockholm University
and the Indian Institute of Technology at Madras, respectively. Those
sets of experiments were tested by Kizilyalli in Ankara, and most
were found suitable. In 1997, several new experiments developed by
Kizilyalli were added to the list.
As a next step, Kizilyalli will reorganize the format of each experiment
to include (1) equipment needed, (2) chemicals needed, (3) time required,
and (4) safety issues at the beginning of the write-up. The plan is
to make the experiments available to interested persons on the IUPAC
web site. Corish will contact John Jost to accomplish this. Spear
will contact Jimmie Edwards for help in preparing the web site. Spear
will also contact Kihlborg to see if the experiments he submitted
for this project are available on a computer disk to save work in
retyping. Spear will also inform the Gordon conference participants
of this project, and will ask for interest and a willingness to contribute
to the testing and editing of written documents. Kizilyalli will inform
the IUPAC Committee on Teaching Chemistry (she is a member) and check
their interest in publicizing the availability of experiments on the
IUPAC web site. Spear is willing to serve as a contact between Kizilyalli
and the IUPAC web site person. He will also determine the possibility
of securing IUPAC funds for secretarial help, if needed.

TF 20 Terminology Used in Sol-Gel Processing
of Advanced Ceramics and Inorganic/Organic Polymeric Substances (Pool
Project 230/30/95 or 410/27/95)
Holland was not present to report. In a written report, she informed
the commission that the contributor to the project from Commission
IV.I is now Dick
Jones of Kent University. Holland met with Jones and other experts
(John Wright and Mark Smith). She included a listing of abbreviations
and terms in her report as an example of the type of information and
style of presentation for the Sol-Gel Nomenclature report. The list
was discussed at the UK/Ireland Sol-Gel Workshop in London in April
and will be shown at the meeting of IUPAC Commission IV.I in July
in Sydney. Holland will also arrange a meeting with Jones, Livage,
and Hess (and possibly others) over the summer of 1998. The aim is
to have a complete draft document of terms at the commission meeting
in Berlin in August of 1999.
Spear will
contact Holland, commend her on the work completed to date, and strongly
encourage her to meet with Livage and other experts. It seems possible
to secure financial support, if needed, and to complete the project
and prepare the final draft document for the IUPAC meeting in Berlin.

PST-19 Thermochemical and Thermophysical Properties
of Refractory Metal Carbides
Balducci was
not present to report. He and De Maria will present a report in July.
Chatillon
may join the project after completion of the mass spectrometry cross-section
project.
