Team Interfaces in Functional Ceramics

In general, microstructure evolution is believed to be a thermally activated process due to its dependence on mass transport by diffusion. However, in functional ceramics as the perovskite SrTiO3 and related materials, non-Arrhenius behavior occurs during microstructure evolution: at higher temperatures, finer microstructures can occur. This unexpected behavior is associated with bimodal microstructures and segregation. Its complete understanding allows tailoring microstructures according to a given need.

Controlling the grain growth rate allows well-controlled unimodal fine-grained or coarse microstructures. Even quasi-single crystalline microstructures can be obtained with grains of a size of 100ds of µm, if segregation and space charge are carefully engineered. This high degree of microstructure control offers immense potential to tailor properties: both ionic and electronic conductivities of grain boundaries are of central importance e.g. for proton conductors (BaZrO3), Li conductors (LixLayTiO3) and oxygen conductors (CeO2) and many other applications.

To obtain full microstructural control, a careful analysis of bimodal microstructure evolution is needed. This can only be achieved by establishing a digital twin, e.g. using a phase field model for bimodal microstructure evolution. The obtained numbers allow investigating nucleation behavior of bimodal microstructures.

Due to the crystalline nature of ceramics, lattices have anisotropic properties. As a consequence, all grain boundary properties are anisotropic as well, e.g. the grain boundary energy, and mobility, but also electric properties and segregation. To evaluate the impact of anisotropy on microstructures and properties, careful model experiments are needed. For example, the anisotropy of the grain boundary energy can be approached by observing the shape of pores or grains in microstructures. Statistical approaches reveal the texture of the grain boundary plane orientation (Grain Boundary Plane distribution) and allow the identification of important grain boundary configurations.

Space charge at a grain boundary forms for thermodynamic reasons: The grain boundary is a 2D lattice defect and results in a fraction of broken bonds and, as a result, lattice stresses. In response, the grain boundary restructures by segregating point defects to the grain boundary core. As these defects bring a charge to the grain boundary plane. This charge is shielded by an accumulation of point defects with inverse polarity next to the grain boundary core. Space charge and segregation are common in functional ceramics and sometimes decrease the performance by orders of magnitude due to the resulting Schottky barriers. Less well-known is the dependence of microstructure evolution on space charge: segregated defects can dominate densification and grain boundary migration. The underlying physics are known since the 60s from metals (‘solute drag'). Accordingly, tailoring microstructure evolution in functional ceramics for a given application needs a fundamental understanding of space charge and segregation. This fundamental understanding is supported by well-established models from the metals community that need to be extended to account for the additional complexity of ionic polycrystals.

Title: Exploring the World Through Binocular Camera Modules

The world of photography and videography has been revolutionized with the advent of binocular camera modules. These modules, equipped with two camera sensors, mimic the human eyes' ability to perceive depth, opening up a new dimension in imaging technology.Get more news about top selling binocular camera module,you can vist our website!

Introduction

Binocular camera modules consist of two camera sensors placed side by side, similar to how our eyes are positioned. This setup allows the module to capture two slightly different views of the same scene, much like our eyes do. The slight difference between these two images, known as disparity, is used to calculate depth information for each pixel in the image, resulting in a depth map. This depth map can be used for various applications such as 3D photography, augmented reality (AR), virtual reality (VR), and robotics.

Working Principle

The working principle of a binocular camera module is based on stereoscopic vision, a technique used by humans and animals to perceive depth. When light from an object reaches our eyes, it forms two slightly different images on our retinas due to the horizontal separation between our eyes. Our brain processes these images and perceives depth based on the disparity between them. Similarly, a binocular camera module captures two images of a scene from slightly different angles. These images are then processed using computer vision algorithms to generate a depth map.

Applications

3D Photography and Videography: Binocular camera modules have made 3D content creation accessible to everyone. By capturing depth information along with color information, these modules allow users to create 3D photos and videos that can be viewed with 3D glasses or VR headsets.

Augmented and Virtual Reality: AR and VR technologies rely heavily on depth information to create immersive experiences. Binocular camera modules provide accurate depth maps that help in placing virtual objects realistically in an AR scene or creating convincing environments in VR.

Robotics: In robotics, binocular camera modules are used for tasks such as object detection, navigation, and manipulation. The depth information provided by these modules helps robots understand their environment better and make informed decisions.

Conclusion

In conclusion, binocular camera modules have opened up new possibilities in imaging technology by adding a third dimension to photography and videography. Their ability to capture depth information has found applications in various fields such as 3D content creation, AR/VR, and robotics. As technology advances, we can expect to see even more innovative uses of binocular camera modules in the future.
