- Reference Formatting: See the Reference Preparation Guide. References should be numbered according to the order in which they
appear in the text.
- Reference Preparation: References should preferably be prepared with EndNote®, ReferenceManager™ or a similar bibliography software package. If references are prepared manually they must be checked for integrity and correctness (you may use ISI Web of Knowledge, PubMed/MEDLINE or Google Scholar). The Editorial Office will charge additional CHF 10 per citation for which extensive corrections must be made.
- Authors List and Affiliation Format: Authors' full first and last names must be given. Abbreviated middle name can be added. For papers written by various contributors a corresponding author must be designated. The PubMed/MEDLINE format is used for affiliations: complete address information including city, zip code, state/province, country, and email address should be added. All authors who contributed significantly to the manuscript (including writing a section) should be listed on the first page of the manuscript, below the title of the article. Other parties, who provided only minor contributions, should be listed under Acknowledgments only. A minor contribution might be a discussion with the author, reading through the draft of the manuscript, or performing English corrections.
- Abstract and Keywords: The abstract should be prepared as one paragraph (about 200 words). A list of three to ten keywords must be given, and placed after the Abstract.
- Figures, Schemes and Tables: Authors are encouraged to prepare figures and schemes in color. Full color graphics will be published free of charge. Figure and schemes must be numbered (Figure 1, Scheme I, Figure 2, Scheme II, etc.) and a explanatory title must be added. Tables should be inserted into the main text, and numbers and titles for all tables supplied. All table columns should have an explanatory heading. Please supply legends for all figures, schemes and tables. The legends should be prepared as a separate paragraph of the main text and placed in the main text before a table, a figure or a scheme.
- Abstract/Table of Contents Graphic: Authors are encouraged to provide a graphical representation of the paper (in either JPEG, GIF, PNG or PDF format) to be used as a graphic of the paper, along with the abstract, on the Table of Contents. The graphic should not exceed 500 pixels width/height. As an example, authors may review the abstract graphic of following papers:
- Electronic Supplementary Information (ESI): Conference slides, video sequences, software, etc., can be included with the submission and published as supplementary material. Please read the information about Supplementary Material Deposit beneath.
Review / Referees
Authors should suggest at least five potential referees with the appropriate expertise, although the Editor will not necessarily approach them. Please provide as detailed contact information as possible (address, homepage, phone, e-mail address). The proposed referees should be experts in the field who can provide an objective report - they should not be current collaborators of the authors nor have published with any of the authors of the manuscript within the last 5 years. Proposed referees should be from different institutions than the authors. You may identify appropriate Editorial Board members of the journal as potential referees. Another possibility is to select referees from among the authors that you frequently cite in your paper.
This journal is published in English, so it is essential that for proper refereeing and quick publication all manuscripts are submitted in grammatically correct English. For this purpose we ask that non-native English speakers ensure their manuscripts are checked before submitting them for consideration. We suggest that for this purpose your manuscript be revised by an English speaking colleague before submission. Authors can also use the services of American Journal Experts (AJE) for this purpose. Authors of articles submitted to MDPI journals benefit of a one-time 10% discount on AJE's charges. Simply follow the above link to make use of the referral discount. Additional fees of CHF 250 will be paid by authors if extensive English corrections must be done by the editors.
