Materials Formatting Requirements: The Submission Package Guide
Materials formatting problems are usually package-discipline problems: the front matter, section structure, highlights, abstract, and data-availability layer all need to support one clear materials-science paper.

Materials key metrics before you format
Formatting to the wrong word limit or reference style is one of the fastest ways to delay your submission.
Why formatting matters at this journal
- Missing or wrong format elements can trigger immediate return without editorial review.
- Word limits, reference style, and figure specifications vary significantly across journals in the same field.
- Get the format right before optimizing the manuscript — rework after a formatting return costs time.
What to verify last
- Word count against the stated limit — check whether references are included or excluded.
- Figure resolution — 300 DPI minimum is standard but some journals require 600 DPI for line art.
- If submitting as gold OA (~$1,800-2,200), confirm the APC agreement before final upload.
Quick answer: Materials formatting requirements are really manuscript-architecture requirements. The current MDPI instructions spell out a research-article structure with front matter, core manuscript sections, and back matter, the abstract should be about 200 words maximum in a single paragraph, highlights are optional but useful, and the data-availability and supplementary-materials layer should already be stable at submission. Most avoidable friction comes from papers that are scientifically fine but still not packaged as one clear materials-science manuscript.
Before you upload, a Materials package review can catch the section-structure, abstract, highlights, graphical-abstract, and data-layer gaps that create avoidable editorial drag.
If you are still deciding whether the journal fit is right rather than just checking the format, use the separate Materials submission guide.
From our manuscript review practice
The highest-friction Materials formatting issue is not template choice. It is whether the manuscript sections, optional highlights, abstract, data-availability layer, and materials claim all line up as one stable MDPI package.
The core Materials package at a glance
Package element | What the journal expects | Why it matters |
|---|---|---|
Front matter | Title, authors, affiliations, highlights, abstract, keywords | The first screen should describe one clear materials paper |
Main sections | Introduction, Materials and Methods, Results, Discussion, Conclusions | A stable manuscript architecture helps a fast workflow |
Back matter | Supplementary Materials, Author Contributions, Funding, Data Availability, Acknowledgments, Conflicts, References | Weak back matter makes the package look unfinished |
Abstract | About 200 words, single paragraph, structured style without headings | The paper should state the question, method, and result efficiently |
Highlights | Optional, 3 to 5 bullets, 120 characters each | Good highlights improve editorial clarity and discoverability |
Graphical abstract | Supported with specific file criteria | The visual summary should reinforce, not blur, the materials claim |
What Materials formatting is actually testing
Because Materials is broad, authors often assume the journal is relaxed about package structure. The opposite is usually true. A broad journal needs a clean manuscript architecture because editors must route and judge a wide range of materials papers quickly.
Working requirement | Strong package behavior | Weak package behavior |
|---|---|---|
Front matter | The material class and contribution are visible immediately | The first screen still reads like chemistry, physics, or engineering |
Section order | The manuscript follows one stable logic from methods to claim | The paper feels adapted from another venue |
Highlights and abstract | The same materials result is described consistently | The highlights and abstract sell slightly different papers |
Back matter | Data and declarations already match the manuscript | The compliance layer still feels provisional |
Our analysis of broad materials-journal packages is that formatting discipline matters most when the science is solid but the identity is still fuzzy. A clean Materials package helps the editor see the paper's center. A loose one makes the manuscript look less mature than it is.
The front matter has to identify one materials paper, not three adjacent ones
The current instructions explicitly describe front matter for research articles. That matters because the first screen has to solve the biggest problem broad journals create: classification.
Front-end element | What strong looks like | Common failure |
|---|---|---|
Title | Concise, specific, and unmistakably about the material contribution | Leads with a broad application rather than the material question |
Highlights | Clarify the materials result in 3 to 5 short bullets | Repeat the abstract or drift into hype |
Abstract | Gives background, methods, and result efficiently | Sounds like a general-purpose science abstract with no materials center |
Keywords | Support how the paper should be discovered and routed | Mix adjacent fields without revealing the primary materials identity |
Editors specifically screen for whether the front matter already tells them what kind of materials paper this is. If one part sounds like catalysis, another sounds like device engineering, and another sounds like polymer science, the package gets harder to route and easier to reject.
The abstract and highlights should compress the same claim
Materials currently says the abstract should be about 200 words maximum, in a single paragraph, following a structured-abstract style without headings. It also treats highlights as optional, with 3 to 5 bullets and up to 120 characters per bullet.
Those requirements create a useful package test:
- can the manuscript state its materials question briefly
- can the paper explain the experimental approach without overloading the abstract
- can the highlights name the main result without turning into marketing copy
- do the highlights and abstract actually describe the same manuscript
We have found that many weak packages pass the abstract rule technically but still fail the clarity test. The abstract and highlights often sound cleaner than the actual manuscript because the paper itself still has too many centers.
Section architecture matters because the journal is broad
Materials currently lays out the expected research-manuscript sections directly. That is not just a template preference. It is a way of enforcing clear scientific order.
Section | What strong looks like | Weak package signal |
|---|---|---|
Introduction | States the material problem and gap clearly | Overviews the field without naming the exact materials question |
Materials and Methods | Makes synthesis, processing, and characterization reproducible | Assumes too much local lab knowledge |
Results | Shows the main structural or performance findings in order | Mixes raw observation and interpretation unclearly |
Discussion | Explains what the findings mean for the material | Repeats the results instead of interpreting them |
Conclusions | Stays short and proportionate | Rebrands the same findings as larger than the paper supports |
We have found that many Materials submissions feel weaker than they are because the section boundaries are not doing their job. The journal is broad enough that the paper must guide the reader firmly.
Graphical abstract, supplementary materials, and the data layer
The current instructions also specify graphical-abstract criteria and make strong statements about data, materials, and protocol availability. Publication implies authors should make associated materials and data available to readers, with restrictions disclosed at submission if needed.
That means the package should already make it easy to verify:
- whether there is a usable graphical abstract or a clear choice not to emphasize one
- what supplementary materials extend the paper
- how the data-availability statement maps to the work actually reported
- whether protocols, datasets, and restrictions are stable
- whether the materials claim would still be credible without hidden files
The supplement should deepen the paper, not rescue it. If the manuscript only becomes reproducible or believable when readers open multiple additional files, the format is still under-edited.
Optional does not mean ignorable
Materials treats highlights as optional, and authors often treat optional items as a sign that they do not matter. In practice, optional package elements can still do real editorial work.
The same is true for the graphical abstract. Not every materials paper needs a flashy image, but the current file criteria show that MDPI expects authors to think carefully about how the paper presents itself. In a broad journal, that extra clarity can help the first read.
We have found that the strongest Materials packages use optional elements selectively and well. They do not add more surfaces to decorate. They use them to make the paper easier to classify and trust.
In our pre-submission review work
In our pre-submission review work with Materials packages, we have found that formatting failures are usually manuscript-identity failures rather than template failures.
The front matter describes a broader paper than the body supports. We have found that many weak packages use clean titles and highlights to promise a sharper materials contribution than the full manuscript actually delivers.
Section order has drifted. Editors specifically screen for whether the manuscript feels stable and intentional rather than adapted from a different venue.
The abstract is compliant but not helpful. Our analysis of weaker packages is that authors often meet the word guidance while still hiding the actual material question.
The back matter is lagging behind the science. Data-availability, contribution, and supplementary-materials sections often remain less settled than the main text.
Optional elements are used badly. Poor highlights or an unfocused graphical abstract can weaken the first read instead of helping it.
Use a Materials formatting and readiness review if you want one pass across front matter, section architecture, highlights, and the data layer before submission.
Submit If / Think Twice If
Your Materials formatting is in good shape if:
- the manuscript format supports one clear materials-science contribution
- the abstract states the question, method, and result efficiently
- highlights, if used, sharpen rather than blur the paper's identity
- the research sections follow a stable and reproducible order
- the supplementary and data layers are already consistent with the manuscript
Think twice before submitting if:
- the first screen still sounds like a different field wearing a materials title
- the abstract and highlights seem cleaner than the full paper
- the section order feels adapted rather than deliberate
- key reproducibility details are living outside the main manuscript
- the data-availability language is still unsettled

What this means the night before submission
Read the title, highlights, abstract, first results subsection, and data-availability statement in one sitting. Those pieces should sound like one coherent Materials paper. If one part sounds like a materials paper, another sounds like a device study, and another still sounds provisional, the package is not ready yet.
This is also the moment to catch avoidable MDPI friction: a front matter block that does not match the article, highlights that duplicate the abstract, or a supplementary-materials plan that still feels improvised.
Frequently asked questions
Materials currently says research manuscripts should include front matter with title, authors, affiliations, highlights, abstract, and keywords; core sections of Introduction, Materials and Methods, Results, Discussion, and Conclusions; and back matter such as supplementary materials, author contributions, funding, data availability, acknowledgments, conflicts, and references.
The current Materials instructions say the abstract should be about 200 words maximum, in a single paragraph following a structured-abstract style without headings.
Materials currently describes Highlights as an optional section, with 3 to 5 bullet points and a maximum of 120 characters per bullet. Optional does not mean useless; they can still sharpen discoverability and editorial clarity.
The biggest mistake is treating the journal as so broad that package discipline no longer matters. If the front matter, sections, and back matter do not all support one clear materials-science contribution, the paper looks weaker than it is.
