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.

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.

Bitmap Graphics

Vector Graphics

4. Image Types and File Formats

Common Bitmap Formats: bmp, pcx, gif, jpg, tif, psd of photoshop etc.

Common Vector Formats: AI, EPS, SVG (AdobeIllustrator), dwg, dxf (AutoCAD), cdr (CorelDRAW), etc.

5. Image Type Conversion

Vector graphics can be converted into bitmap images using graphic design software. However, converting a bitmap image into a vector graphic requires complex and extensive data processing, and the quality of the resulting vector image may vary significantly.

Understanding Image Color Modes

The color mode of an image is a model that expresses a certain color in digital form, or a way to record the color of an image. It is divided into: RGB mode (ideal for digital displays), CMYK mode (optimized for print media), HSB mode (intuitive hue-saturation-brightness representation), Lab color mode (device-independent color space), grayscale mode (scientific imaging and monochrome graphics), indexed color mode (limited palette for web graphics), two-tone mode (elegant duotone effects), and multi-channel mode (specialized color separations).

In scientific research and journal cover design, the most critical color modes are grayscale mode (for microscopy and monochrome data), RGB mode (for on-screen presentations and digital publications), and CMYK mode (for high-quality printed journal covers and figures). Understanding these modes ensures accurate color representation in scientific visuals.

1、Gray scale

Definition: also known as grayscale map, the image expressed in gray scale is called grayscale map.

Grayscale color: pure white, pure black and a series of transition colors from black to white.      

Features: It does not contain any hue, that is, there are no colors such as red and yellow.

2. RGB

RGB mode is mainly used for screen display and is a luminous color mode. All colors in nature can be obtained by combining different intensities of the three color wavelengths of red, green and blue (RGB), which is what people often call the three-primary color principle. It is more suitable for electronic journals and can also be used for paper journals.

3. CMYK

CMYK color mode is a printing mode and a reflective color mode. The four letters refer to Cyan, Magenta, Yellow, and Black, representing four ink colors in printing.

CMYK mode is essentially the same as RGB mode, except that the principle of color generation is different. In RGB mode, the color is generated by mixing the colored light emitted by the light source, while in CMYK mode, the light shines on paper with different proportions of C, M, Y, and K inks. After part of the spectrum is absorbed, the light reflected to the human eye generates color. It is more suitable for paper journals.

4, Notes:

CMYK and RGB are the most common color modes in academic journals.

For the mutual conversion of the two image color modes, the CMYK color range (gamut) and RGB mode are relatively small, so the CMYK mode can be converted to RGB mode, while  RGB mode may cause color distortion when converted to CMYK mode.

For example, the two journal covers below demonstrate how color modes impact design: the left cover is in RGB mode, while the right cover has been converted to CMYK mode. Due to CMYK's smaller color gamut, the hues appear more vivid and abrupt, with weaker transitions. This shift is a common challenge in scientific cover design, where accurate color representation is crucial.

This color mode conversion problem is also frequently encountered by many researchers when making diagrams, We hope today’s discussion helps you navigate these color mode conversions effectively!

When discussing the differences between vector graphics and bitmap images, we touched upon a key characteristic of bitmap images—resolution. Indeed, resolution plays a crucial role in scientific image collection and paper preparation. This article will explore the definition of resolution, how to calculate it, and common issues related to it.

1. Definition of Image Resolution

Image resolution is a unique attribute of bitmap images, referring to the number of pixels contained within an inch of an image. It is measured in DPI (dots per inch), often referred to as "pixels per inch" or "dots per inch." Essentially, resolution determines the level of detail in an image, much like the concept of density in physics.

2. How to Calculate Image Resolution

When we know the physical size of an image and the number of its pixels, we can calculate the size of its resolution with the formula shown below.

3. About image size

One thing to pay special attention to is that when we refer to image size, it is not the physical size of the image but the number of pixels (number size) in the drawing software. Usually, the larger the resolution, the finer the image. As shown in the following figure, the physical size of the same two diagrams, the more the number of its pixel grid, the finer the image.

4. Frequently Asked Questions About Resolution

Q1: Since it is said that the larger the resolution, the finer the image, is it true that the larger the resolution, the better the image quality?

From this extreme example above, it seems that increasing the resolution does not affect the fineness of the image when the image has a single color. So, in the face of more complex color images, the resolution can be appropriately increased, while the color of a single image can meet the demand.

Q2：The difference between PPI and DPI.

ppi (pixels per inch): the sampling rate of the image (in the image, the number of pixels contained in each inch), refers to the smallest point of the screen can be resolved.

dpi (dots per inch): print resolution (the number of dots per inch that can be printed, that is, the printing accuracy), in general, can be understood as the smallest physical device can be resolved unit.

The two use different scenarios (screen and print), the definition is slightly different, can be generalized to some extent.

Q3：Can I put an image into Photoshop by directly increasing the resolution to make the image clearer?

It is possible to get Photoshop to increase the DPI, but there is no practical significance, because the total amount of information the image has has already been determined. If you increase the resolution at the same size, it will only result in an unrealistic enlargement of the pixels in the image (the extra pixels are calculated by difference); if you don't limit the size, you will change the size at the same time as you change the resolution. Therefore, the resolution should be determined at the beginning of the image drawing and not hope to change it later.

Q4：Are there any requirements for image resolution in journal submissions?

In journal submissions, generally for color portfolio images, the image requirements are 300 dpi or higher, depending on the journal's author submission guidelines.

For example, the author guidelines on the PNAS website have the following image resolution requirements:

Please supply high-resolution files whenever possible. Resolution of at least 1200 dpi is needed for all line art, 600 dpi for images that combine line art with photographs/halftones, and 600 dpi for images that combine line art with photographs/halftones. Resolution of at least 1200 dpi is needed for all line art, 600 dpi for images that combine line art with photographs/halftones, and 300 dpi for color or grayscale photographic images. Please review the PNAS Digital Art Guidelines.

This means you can focus on enjoying quality time with your pet, knowing their stroller is built to last.

Everyday Cleaning Tips for Pet Strollers

1. Shake It Out After Every Use

After each walk, take a moment to shake out the stroller’s interior. This simple step helps remove loose fur, dirt, and debris before it settles into the fabric. For pet strollers for dogs, this is especially helpful since larger pets tend to shed more.

2. Keep Wipes Handy

Pet-safe cleaning wipes are a lifesaver for quick cleanups. Use them to wipe down the stroller’s interior, handles, and wheels after each use. This is perfect for tackling muddy paw prints or accidental spills.

3. Vacuum Weekly

Make vacuuming your pet stroller part of your weekly routine. Use a handheld vacuum or a brush attachment to remove hair and dirt from the fabric, seams, and corners. This is a must for pet strollers for cats, as their fine fur can easily get trapped in the material.

4. Spot Clean Stains Immediately

Accidents happen—whether it’s a spilled water bowl or a little “oops” from your pet. Use a mild detergent or pet-safe cleaner and a damp cloth to gently blot stains. Avoid harsh chemicals, as they can damage the fabric or irritate your pet’s skin.

5. Deep Clean Monthly

Once a month, give your pet stroller a thorough cleaning. If the fabric is removable, toss it in the washing machine (check the care label first). Wipe down the frame, wheels, and handles with a damp cloth and mild soap. Don’t forget to clean the undercarriage—it’s a hidden dirt magnet!

Maintenance Tips for a Long-Lasting Stroller

1. Check the Wheels After Outdoor Adventures

If you frequently take your pet stroller on outdoor adventures, inspect the wheels for dirt, rocks, or wear. Clean them with a damp cloth and lubricate the axles if needed to keep them rolling smoothly.

2. Tighten Screws and Bolts

Over time, screws and bolts can loosen from regular use. Every few months, check the stroller’s frame and joints, and tighten any loose parts. This ensures the stroller remains sturdy and safe.

3. Test the Brakes and Safety Features

Before each use, give the brakes a quick test to make sure they’re working properly. Also, check the stroller’s safety features, such as harnesses and zippers, to ensure they’re in good condition. Our pet strollers are designed with the same rigorous safety standards as our baby strollers, so you can trust they’ll keep your pet secure.

4. Store It Properly

When not in use, store your pet stroller in a dry, cool place. If possible, keep it covered to protect it from dust and dirt. This is especially important if you live in a humid climate, as moisture can lead to mold or mildew.

Die-casting is one of the most versatile and efficient manufacturing processes used in industries such as automotive, aerospace, electronics, and consumer goods. It allows manufacturers to produce complex, high-precision metal parts with excellent surface finishes and dimensional accuracy. However, despite its widespread use, many people still find the process somewhat mysterious. In this blog post, we’ll break down the key aspects of die-casting, explain how it works, and outline what you need to know if you’re considering this method for your project.

What is Die-Casting?

Die-casting is a metal casting process in which molten metal is injected under high pressure into a steel mold (also known as a die) to form a part. The process is typically used for metals with low melting points such as aluminum, zinc, and magnesium. Die-casting produces parts that are precise, strong, and lightweight, making it an ideal solution for manufacturing components that require intricate detail and high-volume production.

The Die-Casting Process

The die-casting process involves several key steps, each contributing to the final quality of the product:

• Preparation of the Die: The die, typically made from steel, is designed and built to the specifications of the part to be produced. It is carefully cleaned and lubricated to prevent the molten metal from sticking and to ensure smooth removal of the finished part.
• Molten Metal Injection: Once the die is prepared, molten metal is poured into the injection system. A plunger forces the metal into the die cavity at very high pressure (up to 4500 psi), ensuring that the metal fills all the details of the mold.
• Cooling and Solidification: After the molten metal fills the cavity, it is allowed to cool and solidify. The cooling time depends on the complexity and size of the part. Once solidified, the die is opened, and the part is ejected.
• Finishing: After ejection, the die-cast parts may undergo additional finishing processes such as trimming, polishing, or machining to remove excess material and ensure the part meets the required specifications.

Types of Die-Casting

There are two main types of die-casting processes: hot-chamber die-casting and cold-chamber die-casting.

• Hot-Chamber Die-Casting: This method is typically used for metals with low melting points, such as zinc. The melting pot is integrated with the injection system, allowing the molten metal to be directly injected into the die. This process is faster and more efficient but is limited to metals that don’t corrode the injection system.
• Cold-Chamber Die-Casting: In this method, the molten metal is poured into a separate chamber before being injected into the die. It’s commonly used for materials like aluminum and magnesium, which require higher melting temperatures. Cold-chamber die-casting is more versatile but slower than hot-chamber die-casting.

Advantages of Die-Casting

Die-casting offers a wide range of benefits, making it a popular choice for manufacturers across various industries:

• High Precision: Die-casting is ideal for creating complex parts with tight tolerances and intricate designs.
• Excellent Surface Finish: The smooth surface finish achieved during the casting process often requires little or no additional post-processing.
• High Strength-to-Weight Ratio: Die-cast parts are lightweight yet strong, which is particularly beneficial for industries like automotive and aerospace.
• High Production Speed: Die-casting is well-suited for high-volume production, allowing manufacturers to produce large quantities of parts quickly and cost-effectively.
• Cost-Effective for Mass Production: The initial setup cost for die-casting molds can be high, but the cost per unit decreases significantly in large production runs, making it a cost-effective option for mass production.

When to Use Die-Casting

Die-casting is ideal for parts that require high strength, precision, and a smooth finish. Common applications include:

• Automotive Components: Engine parts, transmission cases, and body parts.
• Aerospace Parts: Structural components, brackets, and housings.
• Consumer Electronics: Housing for phones, laptops, and other devices.
• Industrial Applications: Machinery components, valves, and housings.

However, it’s important to note that die-casting may not be the best choice for every project. It is most suitable for projects with high-volume production needs, where precision and detail are essential.

Challenges in Die-Casting

While die-casting is an efficient process, it does come with its challenges:

• Initial Tooling Costs: The cost of designing and manufacturing the molds can be high, which may not make die-casting cost-effective for low-volume production.
• Material Limitations: Die-casting is typically limited to metals with low melting points, so it’s not suitable for all types of materials.
• Porosity: If not properly controlled, die-casting can result in tiny air pockets within the metal, which can affect the strength and durability of the part.
• Complexity of Design: While die-casting is great for producing complex parts, there are still design constraints that need to be considered, such as wall thickness and draft angles.

Die-casting is a powerful manufacturing process that offers a wide range of benefits, including precision, strength, and cost efficiency for high-volume production. Understanding the key steps and considerations involved can help you decide whether die-casting is the right choice for your project. If you’re considering die-casting for your next manufacturing need, it’s essential to work with experienced professionals who can guide you through the process, from mold design to finished part production.
