Nanometer powder, in recent years, has become an essential material in various fields, including electronic devices, biomedical science, and energy storage systems. To characterize the unique structure and properties of nanometer powders, scanning electron microscopy (SEM) has become an invaluable tool. However, preparing nanometer powders for SEM imaging is non-trivial and requires special attention to avoid data distortion caused by preparation artefacts. In this article, we will discuss the methods for preparing nanometer powders for SEM imaging and demonstrate how SAT NANO's products and services can simplify the preparation process.

​Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.

Nanotechnology is becoming increasingly important in many fields, from medicine to electronics. Nanomaterials, including nanoparticles, nanotubes, and nanowires, are essential components of many nanotechnology applications. Producing these materials requires specialized techniques, such as wet and dry methods. In this article, we will explore what dry and wet methods are, their benefits, and how SAT NANO provides high-quality nanomaterials.

There are several techniques that can be used to test the purity of a powder. One common method is X-ray diffraction analysis (XRD), which can be used to identify and quantify the different crystalline phases in a powder.

​The China International Nanotechnology Industrial Expo, or CHInano for short, is the most authoritative and influential event in the field of nanotechnology application industries. This prestigious conference serves as a meeting place for professionals and innovators from across the globe to showcase their latest products, findings, and technologies. With a focus on nanomaterials, nanomanufacturing, third-generation semiconductors, nanoscale imprinting, nanobiotechnology, energy and clean technology, the CHInano serves as an invaluable platform for building international exchange and collaboration within the nanotechnology industry.

The passivation layer of metal nanoparticles refers to a thin film or protective layer coated on the surface of metal nanoparticles. It usually consists of a compound, such as an oxide, sulfide, or organic compound. This passivation layer can alter the surface properties of metal nanoparticles and provide protection and stability.
