Guide for Authors
The main objective of the publication in ELDJ is the preparation of
electronic files to be used for exchanging numerical data between workshop
members and for storage in data banks. The standard format (SELF) currently
developed by the IUPAC-CODATA Task Group on Standardization of Physico-Chemical
Property Electronic Data Files (IUCOSPED) will be used. Special programs
will permit the conversion of SELF files into formats used by the most
important Data Centers and Data Banks currently associated to the IUCOSPED
Project (DECHEMA, Data Center Praha, Glushko Thermocenter Moscow, NIST,
and TRC). The access to SELF Files will be possible through the Internet-based
Central Data Information Site (DataExplorer) installed at FIZ-Karlsruhe.
The Publisher will supply 20 reprints of each published paper and a diskette containing all the electronic files. Additional reprints may be ordered at extra cost.
For the preparation of the electronic input data files, Authors will receive a modest honorarium depending on the number and size of the data files.
Each ELDJ paper consists of three parts:
I. A Text consisting of Title, Authors, Abstract, Introduction,
Experimental Section (Apparatus, Procedure, and Materials), Results, and
Discussion and Conclusions. It should include references to, and comparison
with, literature data, if available, short description of the experimental
methods used, with references, precision and accuracy of all the measured
physical quantities, source of all the materials, their stated commercial
purity, purification method and purity test used, if any, final purity,
and measured physical constants with comparison with reliable literature
data, if available.
No tables and figures with the primary numerical data should appear in Part I of the paper (see Parts II and III).
Tables with coefficients of correlating equations and auxiliary data used in correlations as well as figures presenting derived data, comparison with correlations or theoretical model calculations, or with literature data, are acceptable.
Authors may report the physical quantities in any units, the Editors will take care of the conversion of all the physical quantities related to the measured or calculated properties in SI units. The only exception is the use of practical units in describing the apparatus and procedure of measurement or of preparation and purification of the materials.
The preferred form of writing the numerical value N of a physical quantity X is:
N = X/10**n (SI Unit)
where n is a positive or negative integer. The factor 10**n is used instead of SI prefixes.
Authors should report temperatures in terms of ITS-90. All molar quantities should be calculated using the IUPAC relative atomic masses of 1995. The molar gas constant R = 8.31451 J K**-1 mol**-1 adopted by CODATA (1986) should be used.
References should be numbered sequentially as they appear in the text. Only papers that are published or accepted for publication should be referenced. In citing the literature the short format below may be followed as an example:
 Kobayashi, M. et al. Fluid Phase Equilib., 1998, 144, 191.
The full reference and the ELDATA Code will be given by the Editorial Office:
[KOBM0990] Kobayashi, M. and Nishiumi, H. 1998. Vapor-liquid equilibria for the pure, binary and ternary systems containing HFC32, HFC125 and HFC134a. Fluid Phase Equilib., 144:191-202.
Part I should be submitted in a single typed copy and should include tables and figures with all labelling. Revised and accepted text can be submitted with the hard-copy on diskette or sent by E-mail (using preferably Microsoft Word).
II. An Appendix consisting of tables and graphs illustrating all or part of the numerical data reported in the paper. This part is automatically generated at the Editorial Office using the electronic input files (Part III).
III. Electronic input files submitted by Authors as standard
ASCII files on diskette or by E-mail.
These files are property-specific and Authors wishing to publish their paper in ELDJ are invited to inform the Editor on the Property and Chemical System for which data are submitted before the Workshop, by December 10, 1999, or sooner, if possible.
The structure of the input files is very simple. An example is given below:
Property: Saturated liquid molar volume
Component 1: Trifluoromethane CHF3
Component 2: Trifluorotrichloroethane CF3CCl3
Column (1): Temperature, Uncertainty: 0.05, Unit: deg C
Column (2): Mole fraction of Component 1, Uncertainty: 0.00002
Column (3): Molar volume, Uncertainty: 0.1, Unit: cm**3mol**-1
(1) (2) (3)
25.00 0.25514 106.8
49.70 0.51703 100.1
Uncertainties should be reported for all the directly measured or derived
The uncertainties take into consideration all possible sources of error (measurement technique, calibration, purity of sample, etc.). They may be reported globally (as shown in the example), either as absolute values (as shown in the example), or relative
(e. g. percent) values, or the sum of both. Otherwise they should be listed in additional columns.
Unit conversions, use of IUPAC chemical nomenclature, and SELF-formatting of the electronic files are done at the Editorial Office.
