The Man of Science appears to be the only
man who has something to say just now and the
only man who does not know how to say it.
SIR JAMES BARRIE
We in science, of necessity, must contribute to the glut of information. But let us
do it with love, especially love of the English language, which is the cornerstone of the
intellectual heritage of the western world;
also do it with energy, the energy we need to put into the scientific paper so that the reader will
not need to use much energy to get the information out of the paper;
husband our materials, especially our words, so that we do not waste inordinate quantities of
paper and ink (or bits) in trying to tell the world more than we know.
LOVE ENERGY
MATERIALS INFORMATION
Publish or Perish?
Whether or not one wholly subscribes to the publish or perish adage, there is no question but
that the goal of scientific research is publication. And scientisits are measured, and become known
(or remain unknown), by theirpublication.
The publication of research results is an essential part of the research process.
A scientific experiment, no matter how spectacular the result, is not completed until the results are
published. In fact, the cornerstone of the philosophy of science is based on the fundamental
assumption that original research mustbe published; only this can new scientific knowledge be
authenticated and then added to the existing data base that we call science.

The research scientist, perhaps uniquely among the trades and professions, must provide a written
document showing what he did, why he did it, how he did it, and what he learned from it.
Thus the scientist must not only do science; he must write science. Although good writing
does not lead to the publication of bad science, bad writing can and often does prevent or delay the
publication of good science.
1.1.2 The Purpose of This Short Course
By presenting certain basic principles that are accepted in most scientific disciplines, it is hoped
that this course will help scientist and students to prepare manuscripts that will have a high
probability of being accepted for publication and of being completely understood when they are
published.1. Define a Scientific Paper
To write a scientific paper, the writer must know exactly whatit is he is doing and why he is doing
it.
To be guilty of dual publication, or to use the work of others without appropriate attribution, is the
type of breach in scientific ethics that is regarded as unforgivable by ones peers. Therefore, exact
definition of what my go into a scientific paper, and what may not, is of prime importance.
2. Parts Analysis of a Scientific Paper
Each individual element of the scientific paper is analyzed, item by item.
Fortunately, there are certain commonly accepted rules regarding the construction of the title, the
Abstract, the Introduction, etc., so that this parts analysis, once mastered, should serve the scientist
throughout his research career.3.Associated Information Either Technical or Related to the Post Writing Stages
Technical information: e.g., how to prepare illustrative material;
Information Related to the Post Writing Stages: e.g., submission, review, and publication
processes.
4. Rules Relating to Primary Scientific Papers Are Adjusted to Fit Different Circumstances
These circumstances include the writing of review papers, conference reports, and theses.
5. Additional Topics
Some of the rules of English as applied to scientific writing;
A sermon against jargon;
A discussion of abbreviations
A sermon against sin.
1.2 What Is a Scientific Paper
1.2.1 Inexact and Exact Definitions
Inexact Definitions:
Perhaps the best answer to the question What is a scientific paper was provided by the wag who
described a drug as any substance which, when injected into a laboratory rat, produces a
scientific paper.It was once said that a scientific paper is not designed to be read. It is designed
8/3/2019 Writing of Scientific Papers
6/23
6
to be published. Although this was said in jest, there is much truth to it. And, actually, if the paper
is designed to be published, it will also be in a prescribed form that can be read, or at least its
contents can be grasped quickly and easily by the reader.
A scientific paper is (i) the first publication of original research results, (ii) in a form whereby
peers of the author can repeat the experiments and test the conclusions, and (iii) in a journal or
other source document which is readily available within the scientific community. Or as Debakey
(1976) said it, the contents of an article shall be new, true, important, and comprehensible
Exact Definitions:
In 1968, the Council of Biology Editors (CBE) arrived at the following definition:
An acceptable primary scientific publication must be the first disclosure (N.B. Now entry into a
computer data base) containing sufficient information to enable peers (1) to assess observations, (2)
to repeat experiments, and (3) to evaluate intellectual processes; moreover, it must be susceptible
to sensory perception, essentially permanent, available to the scientific community without
restriction, and available for regular screening by one or more of the major recognized secondary
services (e.g., currently, Biological Abstracts, Chemical Abstracts, etc., in the United States and
similar facilities in other countries).
N.B. This definition excludes publication such as newsletters and house organs.
1.2.2 Organization and Language of a Scientific Paper
A scientific paper is, or should be, highly stylized, with distinctive and dearly evident component
parts. Each scientific paper should have, in proper order, its Introduction, Materials and Methods,
Results, and Discussion.
Good organization is the key to good writing by M S Peterson (1961)
(i) What was the problem? the Introduction;
(ii) How did you study the problem? the Materials and Methods;
(iii) What did you find? the Results;
(iv) What do these findings mean? the Discussion.
Some people think that the preparation of a scientific paper has almost nothing todo with writing,
per se. it is a question oforganization.
In addition to organization, the second principal ingredient of a scientific paper should be
appropriate language within that organization. We keep emphasizing proper use of English,
because it is in this area that most scientists have trouble.
David B Truman said it well: In the complexities of contemporary existence the specialist who is
trained but uneducated, technically skilled but actually incompetent, is a menace.Language neednot be difficult. In scientific writing, we say: The best English is that which gives the sense in the
fewest short words. Literary tricks, metaphors and the like, divert attention from the message to
the style. They should be used rarely, if at all, in scientific writing.
1.2.3 Other Definitions
Original research report scientific paper;
Research report that are not original, or not scientific, or somehow fail to qualify as scientific
papers a review paper, a conference report, a meeting abstract, etc. A review paper may
8/3/2019 Writing of Scientific Papers
7/23

review almost anything, most typically the recent work in a defined subject area or the work of a
particular individual or group. Thus, the review paper is designed to summarize, analyze, or
synthesize information that has already been published (research reports in primary journals).
Although much or all of the material in a review paper has previously been published, the spectre
of dual publication does not normally arise because the review nature of the work is usually
obvious (often in the title of the publication, such as Microbiological Reviews, Annual Review of
Biochemistry, etc.).
A conference report is a paper published in a book or journal as part of the proceedings of a
symposium, national or international congress, workshop, round table, or the like. Rarely, such
conferences are designed for the presentation of original data, and the resultant proceeding (book
or journal) qualifies as primary publication. More often, such conference presentations are
basically review papers, presenting reviews of recent work of particular scientists or recent work
in particular laboratories. Some of the material reported at some conferences (especially the
exciting ones) is mainly in the form of preliminary reports, in which new, original data are
reported, often accompanied by interesting speculation. But, usually, these preliminary reports do
not qualify, nor are they intended to qualify, as scientific papers. Later, often much later, such
work is validly published in a primary journal; by this time, the loose ends have been tied down,
all essential experimental details are recorded (so that a competent worker could repeat the
experiments), and the speculations are now recorded as conclusions.
Therefore, the vast conference literature that appears in print normally is not primary. If original
data are presented in such contributions, the data can and should be published (or republished) in
an archival (primary) journal. Otherwise, the information may be effectively lost. If publication in
a primary journal follows publication in a conference report, there may be copyright and
permission problems affecting portions of the work (see later discussion on this subject), but the
more fundamental problem of dual publication normally does not and should not arise.
Meeting abstracts, like conference proceedings, are of several widely varying types. Conceptually,
however, they are similar to conference reports in that they can and often do contain original
information. They are not primary publications, nor should publication of an abstract be
considered as a bar to later publication of the full report.
In the past, there has been little confusion regarding the typical one-paragraph abstracts published
as part of the program or distributed along with the program of a national meeting or international
congress. It was usually understood that the papers presented at these meetings would later be
submitted for publication in primary journals. More recently, however, there has been a strong
trend towards extended abstracts (or synoptics). Because it is very expensive to publish all ofthe full papers presented at a large meeting, such as a major international congress, and because
such publication is still not a substitute for the valid publication offered by the primary journal, the
movement to extended abstract makes a great deal of sense. The extended abstract can supply
virtually as much information as a full paper; basically, what it lacks is the experimental detail.
However, precisely because it lacks experimental detail, it cannot qualify as a scientific paper.
Conclusion General acceptance of such definition will greatly clarify both primary and
secondary communication of scientific information.

Lecture 07 Summary and Discussion on Scientific Writing
7.1 A Personalized Summary
Through the years, I have had many occasions to visit various scientific laboratories. Almost
always, I have been impressed, sometimes awed, by the obvious quality of the laboratories
themselves and of the equipment and supplies contained therein. Judging by appearances, one
could only believe that the newest and best (and most expensive) instruments and reagents were
used in these laboratories.
During those same years, I have seen thousands of the products of those same laboratories. Some
of these products (scientific papers) properly reflected the quality and expense that went into their
generation. But many did not.
I want to talk about the many that did not. I ask you, as I have often asked myself, why it is that so
many scientists, while capable of brilliant performance in the laboratory, write papers that would
be given failing marks in a seventh-grade composition class. I ask you why it is that some
scientists will demand the newest ultracentrifuge, even if it costs $40,000, and then refuse to pay
$20 to a commercial artist to draw a proper graph of the results obtained with the ultracentrifuge.
About a dozen similar questions leap to my mind. Unfortunately, I do not know the answers
and I doubt that anyone does.
Perhaps there are no "answers." If there are no answers, that leaves me free to do a little
philosophizing. (If you have gotten this far in this book, you can heroically hang on for another
few paragraphs.)
If we view knowledge as the house we live in, scientific knowledge will tell us how to construct
our house. But we need artistic knowledge to make our house beautiful, and we need humanistic
knowledge so that we can understand and appreciate life within our house.
If we view a scientific paper as the culmination of scientific research, which it is, we can, if we but
try, make it more beautiful and more understandable; we can do this by enriching our scientific
knowledge with a bit of the arts and humanities. A well-written scientific paper is the product of a
well-trained scientist, yes; but the scientist capable of writing a really good paper will also be a
cultured man or woman.
Students of the sciences must not content themselves with study of the sciences; science will be
more meaningful if studied against a background of other knowledge.
Especially, students must learn how to write, because science demands written expression. To
learn to write, you must learn to read. To learn to write well, you should read good writing. Read
your professional journals, yes, but also read Shakespeare.

Many universities now provide courses in scientific writing. Those that do not should be ashamed
of themselves.
What I have said in this book is this: Scientific research is not complete until the results have been
published. Therefore, a scientific paper is an essential part of the research process. Therefore, the
writing of an accurate, understandable paper is just as important as the research itself. Therefore,
the words in the paper should be weighed as carefully as the reagents in the laboratory. Therefore,
the scientist must know how to use words. Therefore, the education of a scientist is not complete
until the ability to publish has been established.

Guidelines for Reviewers
American Society for Microbiology
8/3/2019 Writing of Scientific Papers

The unpublished manuscript is a privileged document. Please protect it from any form of
exploitation. Reviewers are expected not to cite a manuscript or refer to the work it describes
before it has been published and to refrain from using the information it contains for the
advancement of their own research.
As a reviewer, adopt a positive, impartial attitude toward the manuscript under review. Your
position should be that of the author's ally, with the aim of promoting effective and accurate
scientific communication.
If you believe that you cannot judge a given article impartially, please return the manuscript
immediately to the editor, with your explanation. Reviews should be completed within 2 weeks. If
you know that you cannot finish the review within that time, send the manuscript to the editor by
return mail with a note of explanation.
A reviewer must not discuss a paper with its author. Although it may seem natural and reasonable
to discuss points of difficulty or disagreement directly with the author, especially if the reviewer is
generally in favor of publication and does not mind revealing his identity, this practice is
prohibited because the other reviewer and the editor may have different opinions, and the author
may be led into undue optimism by having cleared things up" with the reviewer who made contact
with him directly.
In your comments intended for transmission to the author, do not make any specific statement
about the acceptability of a paper, but advise the editor of your recommendation by checking the
review form at the appropriate place. The responsibility for acceptance or rejection lies with the
editor, who will base the decision not only on advice from reviewers but also on considerations
outside the reviewers' purview. Statements concerning acceptability in a reviewer's comments may,
therefore, run counter to the editor's decision and may have to be deleted.
In your review, consider the following aspects of the manuscript as far as they are applicable:
Importance of research question or subject studied
Originality of the work
Appropriateness of approach or experimental design
Adequacy of experimental techniquesSoundness of conclusions and interpretation
Relevance of discussion
Soundness of organization of the paper (and of the Abstract)
Adherence to ASM style as set forth in Instructions to Authors
Careful attention to the title
Appropriateness for the relevant journal
In comments intended for the author's eyes, present criticism dispassionately and avoid offensive

Therefore, problems of decision are between "modify" and "reject." A paper that requires more
than a trivial amount of experimental material (e.g., a simple enzyme assay or growth rate
determination) to complete the argument should be checked "reject.
When data and experiments appear sound and complete but there are deficiencies in organization
and presentation, the choice of modify or "reject" depends on the extent of the problem. If the
reviewer can follow the argument and feels that the author should be able, with reviewers'
suggestions, to turn out a coherent revision within a month, the choice should be "modify." If the
treatment is so muddled that the meaning of the data comes into question, or the material is
incomprehensible to anyone but a specialist, the choice should be "reject."

2-Hour Lecture on Scientific Writing
by Dr R Q Zheng
Peking University
November 2002
8/3/2019 Writing of Scientific Papers
15/23

Today, I am going to talk about Scientific Writing, as Gaoyuan and I discussed earlier.
However, Scientific Writing is such a big issue, that we certainly can not finish it within one or
two classes, or even within a semester. Upon my understanding, almost every university in the
United States will offer courses related to technical writings during undergraduate education.
Although I myself received my Ph.D. degree in America, I had not taken such classes. So what I
am going to teach today is mostly based on my experience in writing papers and dissertation, and
on some of my readings. I will only introduce some basic ideas, give you some simple examples,
and provide a general guide. Well, I wish after this time, you would start to pay attention to
writing once you get chance to read, to write or even to listen to.
I know, many of you will continue your education after the 4-years
undergraduate life. Students who want to get a master or Ph.D. degree, for example,
at Peking University will be required to publish your research results. Even if this is
not the case, you can not avoid writing in your future work. Because you are
studying chemistry, today I will mostly introduce ACS style in technical writing,where ACS is the abbreviation of American Chemical Society.
1)
Concerning the writing of a scientific paper, specific guideline for text length,
preparation of figures and tables, and instructions on how to submit your paper differ
from journal to journal and publisher to publisher. For ACS journals and special
publications, read the Guide, Notes, Notices, or Instructions for Authors that appear in
each publications first issue of the year and on the World Wide Web at
http://pubs.acs.org.
Writing a Scientific Paper
Guide, Notes, Notices, or Instructions for Authors
http://pubs.acs.org
2)
Although there is no fixed set of writing rules to be followed like a cook book
recipe or an experimental procedure, some guidelines can be helpful. Lets start by
answering some questions:
What is the function or purpose of this paper?----Are you describing original research results?
----Are you reviewing the literature?
----Something else?
How is your work different from that described in other reports on the same
subject? Unless you are writing a review, be sure that your paper will make an
original contribution. Some publishers, including ACS, do not publish previously
published material.
8/3/2019 Writing of Scientific Papers
16/23
16
What is the best place for this paper to be published?
Who is the audience?
Answering these questions will clarify your goals and thus make it easier for youto write the paper.
3)
Standard Format
Here shows an example of standard format when you organize your material into
a paper. In the section of Introduction or Background, you may introduce why you
choose your research topic, what have been done by others in this field; then comes
with experimental details or theoretical basis, where you introduce how to do your
experiments or how to calculate in your study; followed by results and discussion,
which are the main body of the paper; Finally, go to conclusions.
This format has become standard because it is suitable for most reports of
original research. It is basically logical, and it is easy to use. More importantly, it
parallels the scientific method of deductive reasoning: define the problem, create a
hypothesis, devise an experiment to test the hypothesis, conduct the experiment, and
draw conclusions. Furthermore, this format enables readers to understand quickly
what is being presented and to find scientific information easily.
4)
Components of a Paper
Lets go more details of this format. This transparency shows the components of a
paper.
Title:
The title must be briefly and grammatically correct but accurate and complete
enough to stay alone. 1) A two- or three-word title may be too short, but a 14- or
15-world title is unnecessarily long. 2) Avoid phrases such as on the, a sudy of,
research on, report on, regarding, and use of. 3) In most cases, omit the at
the beginning of the title. 4) Spell out all terms in title, and avoid symbols, formulas,
and abbreviations. 5) Serious titles are of little value. Some publishers do not permitthem at all. 6) If you can not create a title that is short, consider breaking it into title
and subtitle.
Byline and Affiliation
Byline: 1) Include in the byline all those, and only those, who made substantial
contributions to the work, even if the paper was actually written by only one person.
2) Use your first name, initial, and surname of each author as requested by
publications. Many ACS publications request at least one full given name for each
author, rather than only initials. 3) Do not include professional, religious, or official
8/3/2019 Writing of Scientific Papers
17/23
17
titles or academic degrees.
Affiliation: Affiliation is the institution at which the work was conducted. If there is
more than one author, use an asterisk or superscript to indicate the author to whom
correspondence should be addressed. This person is usually your boss, and he isfully responsible for the paper. For example, he will submit the paper, write to
editors, answer the questions raised by reviewers, and revise the paper as suggested.
5)
Abstract: Most publications require an informative abstract for every paper, even if
they do not publish abstracts. For a research paper, briefly state the problem or the
purpose of the research, indicate the theoretical or experimental plan used, summarize
the principal findings, and point out major conclusions. The abstract allows a reader
to determine the nature and scope of the paper, and helps editors identify key features
for indexing. Some tips: 1) The optimal length is one paragraph, and between 80and 200 words is usually adequate. 2) Do not cite references, tables, figures in the
abstract. Do not include equations, schemes, or structures that require display on a
line separate from the text. 3) Use abbreviations only when it is necessary. Define
abbreviation in the abstract (and again at first use in the text).
Introductions: A good introduction is a clear statement of the problem or project and
the reasons that you are studying it. The body of the introduction part usually contains
the following contents: 1) to give a concise and appropriate background discussion
of the problem and also the significance, scope and limits of your work; 2) to
outline precious work by citing pertinent literature; 3) to state how your work differs
from or is related to work previously published, and the continuity from the pervious
work to yours.
6)
Experimental Details or Theoretical Basis:
This section may own different names such as experimental methods,
experimental section, or materials and methods, and theoretical calculations,
depending on specific journals or publications. In this section, you need to give
sufficient details about your materials and methods so that others can repeat yourwork and obtain comparable results.
What we usually do in this part is outlined here:
1) Identify the materials used, but do not reference standard lab reagents;
2) Give the chemical names of all compounds and the chemical formulas of
compounds that are new and uncommon;
3) Describe apparatus only if it is not standard or not commercially available;
4) Describe the procedures used, unless they are established and standard;
8/3/2019 Writing of Scientific Papers
18/23
18
5) Note and emphasize any hazards, and include precautionary handling details
and safety measurements;
6) In theoretical reports, include all background data, equations, and formulas
necessary to the arguments, but not lengthy derivations, which may be
presented as Supporting Information.
7)
Results and Discussion
Results and Discussion can be presented either as two separate sections or as one
combined section. In the section of Results, you need to summarize the data collected.
If necessary, include equations, figures, and tables for clarity and brevity.
The purpose of the discussion is to interpret and compare the results. In this
section, you need to relate your results to your original purpose in undertaking the
project: Have you resolved the problem? What exactly have you contributed? You
may also suggest further study in this section. Usually, Results and Discussion are themost important components of a paper.
8)
Conclusions and Summary
The purpose of the conclusion is to put the interpretation into the context of the
original problem. Do not repeat discussion points or include irrelevant material. And
your conclusions should be based on the evidence presented.
The function of summary is similar to that of conclusions. A summary is
unnecessary in most papers. However, in long papers, a summary of the main points
can be helpful. Keep in mind that a summary should be short.
9)
Acknowledgments
Generally, the last paragraph of the paper is the place to acknowledge people,
organizations, and financing. Do it as simple as possible. It is important to follow the
journals guidelines on what to include in the Acknowledgments section.
References
In ACS books and most journals, the style and content of referenced are standard.So, you need to follow the reference style. The best way is to check the journal you
like to publish your paper.
Special Sections and Supporting Information
Special Sections and Supporting Information are not required sections in many
journals. However, if you have large tables, extensive figures, lengthy experimental
procedures, mathematical derivations, analytical and spectral characterization data
and so on, you may include these in the section of Supporting information.

Writing Style and Word Usage
Now, we have had too much for the components of a paper. It has 7 slides
already. Lets change a topic, shift away from the components of a paper, and go towriting style and word usage.
When you are writing information that will be read in English by non-native
speakers, and particularly, when authors themselves are not native English speakers
like us, these approaches can be helpful. You may use minimum word strategy
and use Controlled English and Global English. Both Controlled English and Global
English impose some restrictions on writing style and terminology. And the
Controlled English is more restrictive than Global English. We will not go in details
today, because these approaches are not very much emphasized in ACS style.
Here are some tips for us in technical writing: It is better to start with simple
declarative sentences; Write in your own style, but keep in mind that the scientificwriting is not literary writing, because a scientific writing requires the precise and the
unambiguous.
In the following part of the class today, I will provide some examples in terms of
writing style and word usage. Before doing that, lets have some advice from the
authorities in scientific writing. Here presented an advice from Maeve OConnor:
The best writing in science, as elsewhere, is simple, clear, precise, and vigorous.
Decide what you want to say and say it as simply, informatively, and directly as
possible.
11)
Choosing the correct word or phrase
Use appropriate verb tense
Simple past tense is correct for stating what was done;
Present tense is correct for statements of fact;
Present and simple past tenses may both be correct for results, discussions and
conclusions.
Use an affirmative sentence rather than a double negative.
Watch the placement of the word only. It has different meanings in different places
in the sentence.Be sure that the antecedents of this and that are clear.
Use the proper subordinating conjunctions. While and since have strong connotation
of time. Do not use them when you mean although, because or whereas.
Use the more accurate terms greater than or more than rather than over or in
excess of.

Be brief is the principle in the scientific writing. Cut the unnecessary words
always.

Editorial StyleNext, I will present recommended stylistic and editorial conventions, mainly but
not solely for ACS publications. The style recommended by ACS is, for the most part,
taken from established authoritative sources, such as The Chicago Manual of Style,
Words into Type, and the U.S. Government Printing Office Style Manual.
Hyphenation
Lets start with hyphenation.
1) Prefixes
Most prefixes are not hyphenated. Do not hyphenate following prefixes when
added to words that are not proper nouns.However, hyphens are sometimes used when letters are doubled, or when more
than one prefix is present.
2) Suffixes
Abbreviation
An abbreviation is short form of a word; often the individual letters are
pronounced. In an acronyms, the letters always form a pronounceable word. ACS
is an abbreviation, while IUPAC (International Union of Pure and Applied Chemistry)
is an acronym. If you check out the web site of ACS, you can find a list of
ACS-recommended abbreviations. Again, we will go through quickly for this part.
If a very long name or term is repeated many times throughout a paper, an
abbreviation is needed. Place the abbreviation in parentheses following the spell-out
form the first time it appears in the text. If it is used in the abstract, define it in the
abstract and again in the text.
14)
Gender-Neutral Language
The U.S. government and many publishers have gone to great efforts encouraging
the use of gender-neutral language in their publications. Recent style guides andwriting guides urge copy editors and writers to choose terms that do not reinforce
outdated sex roles. Gender-neutral language can be accurate and not necessary
awkward. 1) Instead of man, use people, human beings or human species,
depending on your meaning. 2) Instead of manpower, use workforce, staff,
workers, labor, crew, employees, or personnel, depending on your meaning. 3)
Instead of manmade, use synthetic, artificial, built, manufactured and
factory-made. 4) Instead of he and his, change the construction to a plural form
(they and theirs) or first person (we, us ours). 5) Instead of wife, use family or

spouse where appropriate.
15)
Numbers, mathematics and units of measure
Usually, the usage of style conventions for numerals and words are different for
technical and non-technical material. Lets see some of examples.
1) Use numerals with units of time or measure, and use a space between the numeral
and the unit, except %, $, and angular degree, angular minutes and angular seconds.
2) With items other than units of time or measure, use words for cardinal numbers less
than 10, use numerals for 10 and above. Spell out ordinals first through ninth,
use numerals for 10th and greater. But there are exceptions.
a. Use all numbers in a series or range containing numbers 10 or great. For example,the 2nd and 10th samples.
b. Use all numerals for numbers modifying nouns in parallel construction in the
same sentence if one of the numbers is 10 or greater.
c. For very large numbers used in a non-technical sense, use a combination of
numerals and words.
1) When a sentence starts with a specific quantity, spell out the number as well as the
unit of measure. However, if possible, you may recast the sentence.
2) Even when a sentence starts with a spell-out quantity, use numerals when
appropriate in the rest of the sentence.
3) Also, we need to use numerals for expressions used in a mathematical sense.
4) When the suffix fold is used in a non-mathematical sense, spell out the
accompanying number even if it is less than 10.
1) In dates, use numerals without ordinal endings.
2) Use numbers for decades, and form their plurals by adding an s. Do not use
apostrophes in any position.
3) Now lets discuss on the numbers of long digits:
If a number is long, this means, it is with five or more digits, we need to considerthe grouping of digits. You need to check the publication in which your manuscript
will appear. Two styles are possible. In some publications, for numbers with five or
more digits, the digits are grouped with commas. But in some publications, the
digits are grouped with a thin space. Examples of both cases are shown here. Keep
in mind, that numbers of four digits are not necessary to be grouped.
There are also exceptions. U.S. monetary values are always written with commas,
never with a thin space. Similar to this, U.S. patent numbers are always written
with commas. Another exception is page number in reference citation, and they are
8/3/2019 Writing of Scientific Papers
22/23
22
always printed solid without commas, without a thin space.
Certainly, there are many other rules in the usage and style of numbers and units.
The best thing is to read the publication and get the information you need.
16)Usage and Style for Symbols
Now lets go the section of the usage and style for symbols. Well just go quickly.
1) Define all symbols for mathematical constants, variables, and unknown
quantities the first time you use in the text. If you use them in the abstract,
define them there and then again at their first appearance in text. But, do not
define standard mathematical constants such as pai.
2) Form the plurals of mathematical symbols by adding an apostrophe and s if you
can not use a word such as values or levels.
3) Do not use an equal sign as an abbreviation for the word is or equals in
text.4) Do not use a plus sign as an abbreviation for the word and.
These are only some examples for the general rules. This next slide gives more
respects in the usage and styles for symbols which you need to pay attention to when
you write a paper. You need to pay attention to which type of word should be used:
italic type, roman type, or boldface type? Also, you need to learn correct use of Greek
letters, spacing, enclosing marks, subscripts and superscripts, abbreviation and
symbols, equation, and special notation.
17)
References
In the following part, I will present style conventions for citing reference. In ACS
publications, you may cite references in three ways.
1) By superscript numbers. The superscript numbers appear outside the
punctuation if the citation applies to a whole sentence or a clause;
2) By italic numbers on the line and in parentheses inside the punctuation;
3) By author name and year of publication in parentheses inside the punctuation.
In ACS books, all three of these systems are used, depending on the subject and
series. Also, in all three systems, the authors name may be made part of the sentence.
18)
Style for Reference Lists
Books:
When a book has authors and no editors, it means either that the entire book was
written by one author or that two or more authors collaborated on the entire book.
When a book has editors, it means that different authors wrote various parts of the
8/3/2019 Writing of Scientific Papers
23/23
23
book independently of each other. The word In before the book title indicates that
the authors mentioned wrote a part of the book, not the entire book.
19)
Conventions in ChemistryConventions in Chemistry are related to the use of typefaces (roman, italic, and
bold), Greek letters, superscript and subscripts, and special symbols that are
commonly used in chemistry.
20)
Editorial Procedures
For ACS books and journals, the specifics may differ from office to office, but the
general procedures for processing manuscripts from review through publication are
similar.
Papers submitted to ACS books and journals are considered for publication withthe understanding that they have not been published or accepted for publication
elsewhere.
