Conflict of interest
All authors are requested to disclose any actual or potential conflict of interest including
any financial, personal or other relationships with other people or organizations within three years of beginning the submitted work
that could inappropriately influence, or be perceived to influence, their work. See also
http://www.elsevier.com/conflictsofinterest.
Submission declaration and verification
Submission of an article implies that the work described has not been
published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration
for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where
the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language,
including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the
originality detection software iThenticate. See also
http://www.elsevier.com/editors/plagdetect.
Changes
to authorship
This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted
manuscripts:
Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange
the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a)
the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from
all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes
confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the
Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform
the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship
has been agreed.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange
author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.
Copyright
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement'
(for more information on this and copyright see
http://www.elsevier.com/copyright). Acceptance of the agreement will ensure
the widest possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript
together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.
Subscribers may reproduce
tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of
the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations
and translations (please consult
http://www.elsevier.com/permissions). If excerpts from other copyrighted works are included,
the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Elsevier has preprinted
forms for use by authors in these cases: please consult
http://www.elsevier.com/permissions.
Retained
author rights
As an author you (or your employer or institution) retain certain rights; for details you are referred to:
http://www.elsevier.com/authorsrights.
Role of the funding source
You are requested
to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe
the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report;
and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.
Please see
http://www.elsevier.com/funding.
Funding body agreements and policies
Elsevier
has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier, to comply
with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements
and policies please visit
http://www.elsevier.com/fundingbodies.
Open access
This
journal offers you the option of making your article freely available to all via the ScienceDirect platform. To prevent any conflict
of interest, you can only make this choice after receiving notification that your article has been accepted for publication. The fee
of $3,000 excludes taxes and other potential author fees such as color charges. In some cases, institutions and funding bodies have entered
into agreement with Elsevier to meet these fees on behalf of their authors. Details of these agreements are available at
http://www.elsevier.com/fundingbodies.
Authors of accepted articles, who wish to take advantage of this option, should complete and submit the order form (available at
http://www.elsevier.com/locate/openaccessform.pdf).
Whatever access option you choose, you retain many rights as an author, including the right to post a revised personal version of your
article on your own website. More information can be found here:
http://www.elsevier.com/authorsrights.
Language and language services
Please write your text in good English (American or British usage is accepted,
but not a mixture of these). Authors who require information about language editing and copyediting services pre- and post-submission
please visit
http://webshop.elsevier.com/languageservices
or our customer support site at
http://support.elsevier.com
for more information.
Submission
Submission to this journal proceeds totally online and
you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single
PDF file of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted
to PDF files at submission for the review process, these source files are needed for further processing after acceptance. All correspondence,
including notification of the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail.
Referees
Please submit, with the manuscript, the names, addresses and e-mail addresses of three potential
referees. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.
Use of wordprocessing software
It is important that the file be saved in the native format of the wordprocessor
used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed
and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words.
However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one
grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic
text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier:
http://www.elsevier.com/guidepublication).
Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also
the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check'
functions of your wordprocessor.
LaTeX
If the LaTeX file is suitable, proofs will be produced
without rekeying the text. The article should preferably be written using Elsevier's document class 'elsarticle', or alternatively any
of the other recognized classes and formats supported in Elsevier's electronic submissions system, for further information see
http://www.elsevier.com/wps/find/authorsview.authors/latex-ees-supported.
The Elsevier 'elsarticle' LaTeX style file package (including detailed instructions for LaTeX preparation) can be obtained
from the Quickguide:
http://www.elsevier.com/latex. It consists of the file: elsarticle.cls, complete user documentation
for the class file, bibliographic style files in various styles, and template files for a quick start.
Article
structure
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.
Theory/calculation
A Theory
section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further
work. In contrast, a Calculation section represents a practical development from a theoretical basis.
Results
A
Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation
for further work. In contrast, a Calculation section represents a practical development from a theoretical basis.
Results and Discussion
may be combined if appropriate and may be organized into subheadings. The Conclusion may be presented in a short section that may stand
alone or form a subsection of a Discussion or Results and Discussion section.
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.
Glossary
Please supply, as a separate list, the definitions of field-specific
terms used in your article.
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. Similarly for tables and figures: Table A.1; Fig. A.1, etc.
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. Contact details must be kept up to date by the corresponding
author.
•
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
A concise and factual abstract is required. The abstract should
state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from
the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s)
and year(s). 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
A Graphical abstract is mandatory for this journal.
It should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership online.
Authors must provide images that clearly represent the work described in the article. Graphical abstracts should be submitted as a separate
file in the online submission system. Image size: please provide an image with a minimum of 531 × 1328 pixels (h × w) or
proportionally more. The image should be readable at a size of 5 × 13 cm using a regular screen resolution of 96 dpi. Preferred
file types: TIFF, EPS, PDF or MS Office files. See
http://www.elsevier.com/graphicalabstracts for examples.
Authors
can make use of Elsevier's Illustration and Enhancement service to ensure the best presentation of their images also in accordance with
all technical requirements:
Illustration
Service.
Highlights
Highlights are mandatory for this journal. They consist
of a short collection of bullet points that convey the core findings of the article and should be submitted in a separate file in the
online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including
spaces, per bullet point). See
http://www.elsevier.com/highlights for examples.
Keywords
Immediately
after the abstract, provide a maximum of 10 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.
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
Follow internationally accepted rules and conventions:
use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult
IUPAC: Nomenclature of Organic Chemistry:
http://www.iupac.org/ for further information.
Database
linking
Elsevier aims at connecting online articles with external databases which are useful in their respective research
communities. If your article contains relevant unique identifiers or accession numbers (bioinformatics) linking to information on entities
(genes, proteins, diseases, etc.) or structures deposited in public databases, then please indicate those entities according to the standard
explained below.
Authors should explicitly mention the
database abbreviation (as mentioned below) together with the actual database
number, bearing in mind that an error in a letter or number can result in a dead link in the online version of the article.
Please
use the following format:
Database ID: xxxx
Links can be provided in your online article to the following databases (examples
of citations are given in parentheses):
•
ASTM: ASTM Standards Database
(ASTM ID: G63)
•
CCDC: Cambridge Crystallographic Data Centre
(CCDC ID: AI631510)
•

Math formulae
Present simple formulae in the line of
normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle,
variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations
that have to be displayed separately from the text (if referred to explicitly in the text).
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.
If
your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is'.
Please
do not:
• Supply files that are optimised for screen use (e.g., 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.
Text graphics
Text
graphics may be embedded in the text at the appropriate position. If you are working with LaTeX and have such features embedded in the
text, these can be left. Further, high-resolution graphics files must be provided separately whether or not the graphics are embedded.
See further under Electronic artwork.
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
Citation in text
Please ensure
that every reference cited in the text is also present in the reference list (and vice versa). 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.
Web references
As
a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author
names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the
reference list) under a different heading if desired, or can be included in the reference list.
References
in a special issue
Please ensure that the words 'this issue' are added to any references in the list (and any citations
in the text) to other articles in the same Special Issue.
Reference management software
This
journal has standard templates available in key reference management packages EndNote (
http://www.endnote.com/support/enstyles.asp)
and Reference Manager (
http://refman.com/support/rmstyles.asp). Using plug-ins to wordprocessing packages, authors only
need to select the appropriate journal template when preparing their article and the list of references and citations to these will be
formatted according to the journal style which is 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.
Examples:
Reference to a journal publication:
[1] J. van der Geer, J.A.J. Hanraads, R.A. Lupton, The art of writing a scientific article,

Video data
Elsevier accepts video material and animation sequences to support and enhance your scientific
research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include these
within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content
and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to
the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one
of our recommended file formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in
the electronic version of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com.
Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be
used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video
instruction pages at
http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in
the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that
refer to this content.
Supplementary data
Elsevier accepts electronic supplementary material
to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting
applications, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online
alongside the electronic version of your article in Elsevier Web products, including ScienceDirect:
http://www.sciencedirect.com.
In order to ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors
should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file.
For more detailed instructions please visit our artwork instruction pages at
http://www.elsevier.com/artworkinstructions.
Mol files
Mol files (optional): Elsevier would like to enrich your online article by visualizing and providing
details of chemical structures you define as the main chemical compounds described. For this purpose, corresponding mol files can be
uploaded via the online submission system. Each compound needs to be submitted as a separate mol file. Please use your preferred drawing
tool to export chemical structures as mol files and ensure that they are unique, complete and do not contain any R-groups or other variables
so that a correct InChI key can be generated. For more information see
http://www.elsevier.com/mol.
Submission

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.2010.09.059
When you use the DOI to create URL hyperlinks to documents on the web, the DOIs 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://get.adobe.com/reader. 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/reader/tech-specs.html.
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 – please let us have all your corrections within 48 hours. It is important to ensure that all
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.
Offprints
The corresponding author, at no cost, will be provided
with a PDF file of the article via e-mail or, alternatively, 25 free paper offprints. If the corresponding author opts for paper offprints,
this preference must be indicated via the offprint order form which is sent once the article is accepted for publication. Additional
paper offprints can also be ordered via this form for an extra charge. 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.
For inquiries relating to the submission of articles (including electronic submission) please
visit this journal's homepage. Contact details for questions arising after acceptance of an article, especially those relating to proofs,
will be provided by the publisher. You can track accepted articles at
http://www.elsevier.com/trackarticle. You can also
check our Author FAQs (
http://www.elsevier.com/authorFAQ) and/or contact Customer Support via
http://support.elsevier.com.
