Guide for Authors
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and
applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers
to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and
includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport
properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation
and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural
products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical
techniques, sensors, and process control methodologies are also within the scope of the journal. The journal publishes original contributions
in all theoretical and experimental aspects of the science and technology of supercritical fluids and processes. Papers that describe
novel instrumentation, new experimental methodologies and techniques, predictive procedures and timely review articles are also acceptable.

Article Structure
All manuscripts are required to be submitted in double-spaced line format. This pertains to all
text, tables, figure captions and references.
Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2,
etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to
"the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line.
Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed
literature survey or a summary of the results.
Material and methods
Provide
sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications
should be described.
Results
Results should be clear and concise.
Discussion
This should explore the significance of the results of the work, not repeat them. A combined
Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which
may stand alone or form a subsection of a Discussion or Results and Discussion section.
Appendices
If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in
appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on.
Essential title page information
•
Title.
Concise and informative. Titles are often
used in information-retrieval systems. Avoid abbreviations and formulae where possible.
•
Author names and affiliations.
Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses
(where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the
author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name,
and, if available, the e-mail address of each author.
•
Corresponding author.
Clearly indicate who will handle
correspondence at all stages of refereeing and publication, also post-publication.
Ensure that telephone and fax numbers (with country
and area code) are provided in addition to the e-mail address and the complete postal address.
•
Present/permanent
address.
If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address"
(or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work
must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
Abstract
Each manuscript must include an abstract of about 100-150 words, reporting concisely on the purpose
and results of the paper. An abstract is often presented separate from the article, so it must be able to stand alone. For this reason,
References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Also, non-standard
or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Graphical Abstract
It is required that the author submits the necessary components of a graphical abstract
(see example). These components
consist of a pictogram, the article title, and the names of the authors and their respective affiliations as they appear in the article.
Maximum final dimensions of the pictogram are 5 X 5 cm with a required minimum pixilation of 300 ppi. Bear in mind readability after
reduction, especially if using one of the figures from the article itself. Graphical abstracts will be collated to provide a contents
list for rapid scanning.
Keywords
Immediately after the abstract, provide
a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and",
"of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used
for indexing purposes. Keywords should be selected, if appropriate, from the following classes: theoretical methods, experimental methods,
phenomena, materials, and applications.
Abbreviations
Define abbreviations
that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable
in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout
the article.
Acknowledgements
Collate acknowledgements in a separate section
at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or
otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof
reading the article, etc.).
Nomenclature and units
Units: The
SI system should be used for all scientific and laboratory data; if, in certain instances, it is necessary to quote other units, these
should be added in parentheses. Temperatures may be given in Kelvin or degrees Celsius. The unit 'billion' (10
9 in America,
10
12 in Europe) is ambiguous and must not be used.
Symbols and Abbreviations: Only widely accepted symbols and
forms of abbreviation should be used, but always give the full expression followed by the abbreviation the first time it appears in the
text. Abbreviations and symbols used in tables and figures should be explained in the legends. The number of symbols should not exceed
10 per manuscript.
Footnotes
Footnotes should be used sparingly. Number
them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into the text, and this
feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves
separately at the end of the article. Do not include footnotes in the Reference list.
Table footnotes
Indicate each
footnote in a table with a superscript lowercase letter.
Artwork
Electronic artwork
General points
• Make sure you use uniform lettering and sizing
of your original artwork.
• Save text in illustrations as "graphics" or enclose the font.
• Only use the following
fonts in your illustrations: Arial, Courier, Times, Symbol.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
•
Produce images near to the desired size of the printed version.
• Submit each figure as a separate file.
A detailed guide
on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions
You are urged
to visit this site; some excerpts from the detailed information are given here.
Formats
Regardless of the application
used, when your electronic artwork is finalised, please "save as" or convert the images to one of the following formats (note the resolution
requirements for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save
the text as "graphics".
TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line
drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.
DOC, XLS or PPT: If your electronic artwork is created in any of these Microsoft Office applications please supply "as is".
Please
do not:
• Supply embedded graphics in your wordprocessor (spreadsheet, presentation) document;
• Supply files that
are optimised for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.
Color
artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct
resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge,
that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations
are reproduced in color in the printed version.
For color reproduction in print, you will receive information regarding the costs
from Elsevier after receipt of your accepted article. Please indicate your preference for color in print or on the Web only. For
further information on the preparation of electronic artwork, please see
http://www.elsevier.com/artworkinstructions.
Please
note: Because of technical complications which can arise by converting color figures to "gray scale" (for the printed version should
you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.
Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached
to the figure. A caption should comprise a brief title (
not on the figure itself) and a description of the illustration. Keep
text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Tables
Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the
table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that
the data presented in tables do not duplicate results described elsewhere in the article.
References
References should be relevant and up-to-date.
All publications cited in the text should be presented in
a list of references and vice versa following the text of the manuscript. In the text refer to references by a number in square brackets
on the line (e.g. Since Lever [1] ), and the full reference including the title should be given in a numerical list at the end of the
paper. Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended
in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the
standard reference style of the journal and should include a substitution of the publication date with either "Unpublished results" or
"Personal communication". Citation of a reference as "in press" implies that the item has been accepted for publication.
All manuscripts
must consistently adhere to the Reference Style as described below.
Reference
style
Text:
Indicate references by number(s) in square brackets in line with the text. The actual authors
can be referred to, but the reference number(s) must always be given.
Example:
"..... as demonstrated [3,6]. Barnaby
and Jones [8] obtained a different result ...."
List:
Number the references (numbers in square brackets) in the
list in the order in which they appear in the text. Each reference appearing in the list must have been referred to in the text.
Reference to a journal publication:
Full journal names should be used in reference to a journal publication. However,
for "Journal" or "Journal of", the abbreviation of "J." is acceptable as in "J. Supercritical Fluids" or "Chemical Engineering J."
Authors' initials and last names should be followed by the full title of the article, full journal name, volume, year in parentheses,
and the pages.

Use of the Digital Object Identifier
The Digital Object Identifier (DOI)
may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to
a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium
for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The
correct format for citing a DOI is shown as follows (example taken from a document in the journal
Physics Letters B):
doi:10.1016/j.physletb.2003.10.071
When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed never to change.
Proofs
One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do
not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download
the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe
Reader version 7 (or higher) available free from
http://www.adobe.com/products/acrobat/readstep2.html. Instructions on how
to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site:
http://www.adobe.com/products/acrobat/acrrsystemreqs.html#70win.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and
return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then
mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan
the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the
text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission
from the Editor. We will do everything possible to get your article published quickly and accurately. Therefore, it is important to ensure
that all of your corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent
corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of
your article if no response is received.
A note added in proof must be
dated and the author must have requested and received the Editor's approval.
Offprints
The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail. The PDF file is a watermarked
version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions
of use. Additional paper offprints can be ordered by the authors. An order form with prices will be sent to the corresponding author.
For inquiries relating to the submission of articles (including electronic submission
where available) please visit this journal's homepage. You can track accepted articles at
