Guidelines for specific journals

Applied Physics Letters (APL)

Manuscript Length

Manuscripts should not exceed 3500 words (approximately four printed journal pages). Abstract, title, author list, references and acknowledgments are all excluded from the 3500-word limit. Figures, tables, and equations, however, are included and must be accounted for by calculating a word count equivalent to the space they occupy. Circumvention of the length limitation by dividing a long article into smaller parts is contrary to the purpose of this journal.

Please use these guidelines for estimating length.

TeX users

Authors are advised to use the REVTeX 4.1 APL style file. If the double-column version of the manuscript obtained using the “reprint” option fits on four pages, the length is acceptable.

Word users

Highlight the manuscript text, excluding abstract, author list, acknowledgements and references, and note the word count at the bottom of the screen. Add to that the word-count-equivalents for figures, tables and equations as follows:

  • Figures: An average single-column figure will displace 220 words. For a more accurate estimation, use the following: {150/aspect ratio) + 20 words] for single-column figures, and [(300/(0.5 x aspect ratio)) + 40 words] for double-column figures. Aspect ratio = width/height.
  • Tables: 6.5 words per line, plus 13 words for single-column tables. 13 words per line, plus 26 words for double-column tables.
  • Equations: 16 words per row for single-column equations. 32 words per row for double-column equations.

If the total number of words (text + figures + tables + equations) is 3500 or less, the length is acceptable.

Comments and Responses

A Comments section is available for criticism or additions to Letters already published. A Response will normally be solicited to a critical Comment. Comments and Responses should not exceed 1000 words.

Biomicrofluidics (BMF)

Fast Track Articles

BMF Fast Track articles replace Brief Communications to report on the most novel, high impact, cutting edge and technically significant developments in the field. Because of the urgency and scientific importance of the work, Fast Track articles have an accelerated review process. Fast Track articles will also receive prioritized consideration for the journal's Editor’s Picks and AIP Publishing press releases.

For consideration as a Fast Track article, the manuscript must

  • be highly original, reporting the most novel, significant, relevant and timely advances in the field,
  • be of the highest scientific quality,
  • be written in a clear and concise manner with no further need for technical/grammatical editing, and
  • adhere to the length guidelines.

Papers submitted to Fast Track will be initially screened for novelty and quality by the Editors and then reviewed by Editorial Advisory Board members, with a review response in under 14 days. Fast Track authors are requested to respond to reviews within 10 days.

Fast Track Article Length

Fast Track Articles should not exceed 2000 words (approximately three printed journal pages). Abstract, title, author list, references and acknowledgments are all excluded from the 2000-word limit. Figures, tables, and equations, however, are included and must be accounted for by calculating a word count equivalent to the space they occupy. Note that the abstract itself should not exceed 100 words.

Please use these guidelines for estimating Fast Track Article length.

TeX users

Authors are advised to use the REVTeX 4.1 BMF style file. If the version of the manuscript obtained using the “reprint” option fits on three pages, the length is acceptable.

Word users

Highlight the manuscript text, excluding abstract, author list, acknowledgements and references, and note the word count at the bottom of the screen. Add to that the word-count-equivalents for figures, tables and equations as follows:

  • Figures: An average single-column figure will displace 220 words. For a more accurate estimation, use the following: 150/aspect ratio + 20 words for single-column figures and 300/0.5 X aspect ratio + 40 words for double-column figures. Aspect ratio = width/height.
  • Tables: 6.5 words per line, plus 13 words for single-column tables. 13 words per line, plus 26 words for double-column tables.
  • Equations: 16 words per row for single-column equations. 32 words per row for double-column equations.

If the total number of words (text + figures + tables + equations) is 2000 or less, the length is acceptable.

Supplemental Material (e.g., supporting information, multimedia, etc.) is accepted for Fast Track articles; however, it must not contain or discuss/interpret essential results, and must not be considered an extension of the manuscript. Failure to adhere to these guidelines may result in either delay in processing of the manuscript or rejection at initial screening. A Fast Track manuscript that is rejected at initial screening may be resubmitted as a 'regular' original-research paper.

Chaos (CHA)

Lead Paragraph

Please establish the first paragraph of the article as a Lead Paragraph containing the main points of the article in terms accessible to nonspecialist readers, and provide the “big picture”.

The Journal of Chemical Physics (JCP)

JCP Communications

These are preliminary reports of highly significant work whose rapid publication will be important to a relatively large number of workers in the field. Communications may be complete in themselves or may be followed by Articles, which present substantial additional significant information. Communications have a length limit of four journal pages. Because of the length limitation, the standard of proof required to support the scientific argument is relaxed somewhat. Scientific arguments that are plausible and, if correct, important, may be presented in Communications even if the detailed proof must be presented in a later publication. Arguments that are implausible but can be demonstrated by lengthy and detailed proof to be correct should not be presented in Communications. Communications are given priority attention in both the peer-review and production processes.

As JCP Communications have a length limit of four journal pages, manuscripts should not exceed 3500 words. Please use these guidelines for estimating length.

TeX users

Authors are advised to use the REVTeX 4.1 JCP style file. The double-column version of the manuscript obtained using the "reprint" option will indicate the whether the length is acceptable.

Word users

Highlight the manuscript text, excluding abstract, author list, acknowledgements and references, and note the word count at the bottom of the screen. Add to that the word-count-equivalents for figures, tables and equations as follows:

  • Figures: An average single-column figure will displace 220 words. For a more accurate estimation, use the following: 150/aspect ratio + 20 words for single-column figures and 300/0.5 X aspect ratio + 40 words for double-column figures. Aspect ratio = width/height.
  • Tables: 6.5 words per line, plus 13 words for single-column tables. 13 words per line, plus 26 words for double-column tables.
  • Equations: 16 words per row for single-column equations. 32 words per row for double-column equations.

If the total number of words (text + figures + tables + equations) is 3500 or less, the length is acceptable.

Journal of Physical and Chemical Reference Data (JPCRD)

Uncertainties

The objective of JPCRD is to provide critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation. Such data are of little use without a quantitative characterization of uncertainties that includes effects of both random (precision) and systematic (bias) uncertainties, as well as a discussion of sources of errors and the rationale for assigning uncertainty estimates. For a more detailed discussion of uncertainty analysis, we refer authors to:

  • U.S. Guide to the Expression of Uncertainty in Measurement, ANSI/NCSL Z540-2-1997, American National Standard for Expressing Uncertainty (National Conference of Standards Laboratories, Boulder, CO, 1997).
  • B. N. Taylor and C. E. Kuyatt, Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results, NIST Technical Note 1297 (NIST, Gaithersburg, MD, 1994).

Units, symbols, terminology, and chemical nomenclature

It is the policy of JPCRD to follow the recommendations of recognized international bodies such as ISO, IUPAC, and IUPAP unless there are strong grounds for making an exception. Sources of recommendations on symbols, terminology, and units are the following:

  • Quantities and Units, ISO Standards Handbook, 3rd ed. (International Organization for Standardization, Geneva, Switzerland, 1993).
  • Quantities, Units and Symbols in Physical Chemistry (the Green Book), 3rd ed. (IUPAC, RSC Publishing, Cambridge, 2007).
  • Symbols, Units and Nomenclature in Physics, IUPAP Document IUPAP 25, 1985. [Reproduced in Physica A 146, 1 (1987)].
  • A. Thompson and B. N. Taylor, Guide for the Use of the International System of Units (SI), NIST Special Pub. 811, 2008 edition (NIST, Gaithersburg, MD, 2008).

The International System of Units (SI) should always be employed unless the Editor has granted an exception. The nomenclature practices of Chemical Abstracts, or those based on the IUPAC recommendations, should be followed. If you are preparing compound indices for your paper, please consult the current CA Index Guide. It is desirable to include CAS Registry Numbers in papers that give data for multiple chemical compounds.

Please follow the conventions for using Roman and italic type. Roman (non-italic) type is always used for chemical formulas, units, numbers, mathematical constants and operators (π and ln), and descriptive terms. Italics are used to denote variables, physical quantities, and functions.
Following are some examples of correct usage:

Tmin = 273 K (italicize physical quantity temperature, not descriptive “min” or unit “K”)

(Don’t italicize operator “exp” or subscript “B” for Boltzmann.)

Avoid the ambiguous term “log”; natural logarithms should be written “ln” (preferred) or “loge” while base-10 logarithms should be written “lg” or “log10”. Please use a minus sign (−) rather than a hyphen (-) to denote negative numbers or subtraction. Superscripts or subscripts should be formatted through the font group rather than raising or lowering the individual characters.

List of symbols

A list of symbols is optional. It is recommended to use a list of symbols if the paper contains many symbols, whose meaning is not obvious, especially if the paper is relatively long. Otherwise, symbols should be defined when they first appear in the text.

Headings and Subheadings

Headings and subheadings in the text should have a minimum of three levels and should be numbered as follows:

  • 1. (Main level)
  • 1.1. (Second level)
  • 1.1.1. (Third level)

The first numbered level is normally “1. Introduction” and the last is “References.” Refer to sections in the text as Sec. 1.1., etc., except at the beginning of a sentence where “Section 1.1.” should be used.

Physics of Fluids (PHF)

Letters

The purpose of the Letters section is to provide rapid dissemination of important and time-sensitive new results in the fields regularly covered by Physics of Fluids, in the form of a condensed communication. Results of extended research should not be presented as a series of Letters in place of comprehensive articles. Except for length, Letters manuscripts are governed by the same criteria as for longer articles. However, ordinarily there is a three-month time limit, from date of receipt to acceptance, for processing Letters manuscripts. Timeliness, current importance of the subject matter, and brevity and clarity of presentation determine the acceptability of contributions. Feasibility studies and proposals for future research are not appropriate for the Letters section and seldom will be accepted. When submitting a manuscript, you must include a brief statement justifying its rapid (and time-critical) publication in the Letters section. Each Letter should be self-contained and may on occasion be followed by a comprehensive article in Physics of Fluids or elsewhere. Letters are limited to seven (7) printed pages in length, including space for title, figures, tables, references, and an abstract limited to 100 words; Letters do not have section headings.

Guidance is provided for page limitations if you use the LATeX template. In 2012, Physics of Fluids had a format change. The “reprint” option has been changed to reflect the new format; single column, single spaced.

Reference List

Note that including the article title within all references on the list is preferred by the community. As such, we ask that you please style your references, as follows: D. A. Lockerby, J. M. Reese, and M. A. Gallis, “The usefulness of higher-order constitutive relations for describing the Knudsen layer,” Phys. Fluids 17 (10), 100609 (2005).

Physics of Plasmas (PoP)

Manuscript Length for PoP Letters and Brief Communications

Manuscripts for Letters in Physics of Plasmas, as well as for Brief Communications, should not exceed 3500 words (approximately four printed journal pages). Abstract, title, author list, references and acknowledgments are all excluded from the 3500-word limit. Figures, tables, and equations, however, are included and must be accounted for by calculating a word count equivalent to the space they occupy. Circumvention of the length limitation by dividing a long article into smaller parts is contrary to the purpose of this journal.
