How to Write an Effective Chemistry Research Paper (Part 1)

Here, we will state the rules about the format and content of a research paper in chemistry and explain the scientific conventions used in chemistry papers.

Format and Content of Chemistry Articles

Readers expect two things while reading your paper:

  • Understand the information presented
  • Know that the findings are legitimate

How to Fulfill these Objectives?

  • Introduction
  • Methods and Materials
  • Results
  • Discussion

This format may slightly differ depending on the journal; for instance, some journals ask you to include an abstract or separate section for the hypothesis. Overall, however, this represents a textual version of the scientific method.

Title

Select terms that are as precise as the text permits.

Examples

Avoid: A magnetic alloy

Use: A vanadium-iron alloy

Things to Avoid

  • Phrases such as “on the,” “a study of,” “research on,” and “regarding.”
  • Non-quantitative, meaningless words such as “rapid” and “new.”

Abstract

A quality abstract distinctly identifies the objective of the experiment and the key outcomes.

Things to Avoid

  • Beginning with “The purpose of this experiment was…” Such background information belongs in the Introduction section.
  • RBe specific about what was done.
  • Vague statements such as “…a metal complex was prepared, and the percent yield was calculated.
    • Instead use, “…hexaammine cobalt (III) chloride was prepared from cobalt (II), chloride, and hydrogen peroxide. The yield was 8.45 g.

Tip 1

When writing a full report, write the Abstract last.

Introduction

Go step-wise!

  • Begin by describing the larger area of the research
  • Give examples of advancement in the field
  • A distinct statement of the research problem
  • Approach being addressed in the current report

Examples

Avoid: This experiment intends to investigate upon any measurable amounts of Nickel in the surrounding mud area and within barnacles living on the pilings.

Use: The purpose of this study is to determine the nickel content in the surrounding mud area and in the barnacles living on the pilings.

Methods and Materials

Include a description of your experimental procedure and the names of instruments used. Do not rewrite the lab manual or protocol.

Examples

Avoid: Next, prepare copper solution. Weigh 0.1821 g of copper nitrate and dilute it in 10 mL of tap water.

Use: A solution was prepared by dissolving copper nitrate (0.1821 g) in tap water (10 mL).

Further subdivide into

  • Materials—sources and purity of reagents used
  • Preparation of compounds—with the procedure and summary of characterization by NMR, IR, etc.
  • Instrumentation—manufacturer, description of any adaptation, or sample preparation

Tip 2

A quality Materials and Methods section should allow the reader to holistically reproduce what you did in the lab, using what you have written.

Outcomes

Include an outline of your raw data, preferably aided by tables and figures, and main observations.

Tip 3

Don’t include lengthy tables of raw data; instead, simply present the outcomes of your calculations.

Avoid: The following standard concentrations were used to follow X law for the absorbances at the corresponding wavelength (Table).

Use: The standard concentrations were measured at the corresponding wavelengths and the data provided in Table 1.

Figures, Tables, Equations

Explain the objective of each figure, scheme, equation, and table in the Results section. When referring to a figure, table, or equation, use its number in the text.

Examples

A plateau was observed at reduced pressures >0.1, as indicated in Table 1.

Indicate every figure, table, and equation with a number. Figures and tables need a number and a descriptive title, and equations usually have a number placed in parentheses at the right margin.

Examples

Figure 1. Mass Uptake vs. Reduced Pressure for A

Table 1. Powder Diffraction Data Obtained for A

A = B2                                                                            (1)

Tip 4

“Figure” is much preferred compared to the labels “chart” and “graph.”

Discussion

  • Analyze your outcomes
  • Comment on the objective of the experiment
  • Explain what the outcomes point to
  • What are the sources of inaccuracy (experimental uncertainty/precision) and limitations?
  • What further experiments could help address any open questions or loose ends?
  • Do the outcomes agree with what others have discovered?
  • Do the outcomes endorse a model or hypothesis?

Examples

Avoid: If, for example, we could have used a red and green apple to determine the components, we could have averaged the data and obtained more accurate results.

Use: For example, if data were obtained from both a red and a green apple, the averaged results could provide more representative values.

Conclusion

Summarize your outcomes and discussion with a concise conclusion, phrasing it in terms of the broad-ranging questions addressed in the Introduction.

Tip 5

When testing a hypothesis, you may want to say that the hypothesis was “proved” or “disproved” or was “correct” or “incorrect.”

Remember, you are testing a theory with a procedure that lasts only a handful of hours and depends on only a few trials, which seriously compromises your ability to be certain about the “truth” you see.

Consequently, words such as “supported,” “indicated,” and “suggested” are more suitable to evaluate your hypothesis.

In the next article, we will discuss the scientific conventions and styles used in chemistry articles.
