SCI Figure Design A Brief Discussion on Paper Figure Layout

When creating figures for academic papers, the first thing we need to determine is the layout (dimensions) of the images. Designing and drawing on the wrong layout often leads to unnecessary trouble at the final submission stage. Guidelines for image layout requirements are usually clearly stated in the publisher’s Guide for Authors. If not, it's recommended that authors contact the publisher directly—this clarifies the requirements and demonstrates professionalism, attention to detail, and respect for the journal.

Here, we’ll briefly discuss the common layouts used in scientific figures.

Aside from a few specialized journals (such as Science and certain physics publications), most academic journals use a two-column layout. In this context, we focus on two key dimensions: L1 (single-column width) and L2 (double-column width).

When we begin designing and drawing a figure, the first thing to consider and determine is the width of the image—whether to adopt a single-column or double-column layout.As for the height, it can generally be adjusted freely.Below are examples of double-column and single-column layouts.

Why Scientists Need Designers and Illustrators?

Science is driven by objective facts and rigorous logic; design emphasizes aesthetics and visual storytelling. At SONDII, we combine scientific knowledge with artistic design—offering services in academic illustration, journal cover design, and scientific animation—to transform your ideas into stunning visuals and elevate the impact of your research.

1. Science Is Complex—Design Makes It Visible

Modern scientific research is incredibly complex. From high-throughput sequencing to big data and climate models, the outcomes are often presented through dense graphs and highly technical language. A good designer or illustrator can “translate” this abstract, often overwhelming information into visuals that are intuitive and easy to understand.

Whether it’s a detailed illustration of a cell structure or a dynamic animation of a biological process, visuals often communicate more effectively than pages of text. Whether you're sharing with fellow researchers or engaging the public, design plays an irreplaceable role.





2. Good Design Increases Scientific Impact

In today’s information-saturated world, a striking cover image or infographic can make all the difference in getting your work noticed. More and more scientific journals are recognizing the power of visual communication—not just accuracy in data, but clarity and visual appeal in how it's presented.

Designers can help scientists create visuals that are both logically sound and visually compelling, improving the overall quality of research presentation and outreach.



3. Storytelling Is Key—Design Is the Visual Medium

Effective science communication is about more than just facts—it’s about telling a story. Design is a powerful tool for conveying those stories visually. Whether you're curating an exhibition, posting on social media, or writing a science article, experienced designers can help transform complex processes into emotionally engaging and visually impactful narratives.

 

We offer custom design services for the scientific community, including journal cover design, scientific illustration,and principle-based animations, helping researchers showcase their work with clarity, beauty, and impact.

Design and discussion Catalytic Reaction and Cover Design

Research on catalytic materials and catalytic reactions has always been one of the hotspots for scholars, and so are the cover articles related to them. Because of the different research focuses of different articles, some focus on the catalytic reaction itself, some discuss the preparation of catalytic materials, and some pay more attention to the improvement of catalytic efficiency. In addition, the concept of catalysis is a little abstract, which brings certain difficulties to our cover design, how to turn abstract into concrete, highlight the key points and take the overall situation into account, which becomes a problem that all cover designers need to think about. Here, we cite several catalytic cover designs for different research focuses for your discussion.

 

NO.1 Focus on the overall reaction process

The figure below is a cover art published in ChemComm, whose main research object is an organic synthesis reaction. This kind of cover art needs to show the whole process of the reaction, so in the design idea, we need to consider that the substrate, the product and the catalyst appear in the movie at the same time.

 

We used the method of building scenes, comparing the two actions of "crossing the bridge" and "reacting" to show the overall appearance of the reaction.

 

NO.2 Focus on Catalyst Preparation

Sometimes, our main concern is the preparation of a catalytic material rather than a specific reaction. In such cases, our design approach should shift toward the catalyst itself, completely setting aside the reaction process to highlight the key focus.  

 

The illustration shown is a cover artwork published in Catalysis Science & Technology. It metaphorically represents the preparation process as a road, where a vehicle moves forward, gradually transforming metal elements into stable single-atom catalysts.

 

NO.3 Focus on Enhancing Catalytic Rate

When discussing catalytic reactions, reaction rate is an ever-present topic. Since rate itself is an abstract concept without a physical form, it is often represented through analogies with real-world objects that embody speed.  

 

For instance, an article published in Advanced Electronic Materials uses a comparison between a horse-drawn carriage and a high-speed train to vividly illustrate and compare catalytic efficiency.

 

 

NO.4 Focus on the Catalyst Itself

As the saying goes, “the essence remains unchanged despite variations.” The catalyst is always one of the fundamental cores of a catalytic reaction. Therefore, many cover articles prominently feature the catalyst itself or its representative imagery at the center of the cover design.  

This approach is one of the most classic representations in catalyst-related cover artworks.

 

 

The above are common design approaches for cover artworks related to catalytic research, providing valuable references. However, the latest creative ideas often capture attention more effectively. Therefore, we should continuously explore new concepts and strive for innovation together.

SCI Drawing Knowledge Bitmap & Vector Graphics

When drawing scientific illustrations, we often face the choice between bitmap and vector graphics. This article will focus on exploring their definitions and differences for reference.

 

1. Image Types and Definitions

Vector Graphics: Composed of mathematically defined curves, with anchor points and paths as their basic components.

 

 

Bitmap Graphics: Also known as raster or pixel graphics, they are composed of individual pixels. When magnified, it becomes evident that the image consists of tiny square pixels.

 

 

2. Image Types and Resolution

Vector Graphics: They are resolution-independent, meaning they can be scaled to any size and printed at any resolution without losing clarity.

Bitmap Graphics: Composed of pixels, so when an image is enlarged, the pixels also get bigger. Since each pixel has a single color, enlarging a bitmap image results in the well-known pixelation effect.

 

3. Image Types and Color Representation

Bitmap Graphics: Capable of displaying rich and detailed colors, making them ideal for realistic images of natural objects.

Vector Graphics: Due to mathematical constraints, they have limited color representation and cannot effectively depict realistic objects. Instead, vector graphics are often used for icons, logos, illustrations and other simple, clear designs.

In the following images, you can see that bitmap graphics display a wider range of colors.
