​Transmission electron microscopy (TEM) is an indispensable research tool in fields such as materials science and nanotechnology. For researchers who are new to TEM, understanding its basic principles and operations is crucial for efficient utilization of this equipment. TEM testing mainly focuses on the microstructure characteristics of materials, including element distribution, phase composition, crystal defects, etc. These characteristics are manifested at the microscopic level as the size, shape, distribution of different phase grains, as well as the density and distribution of crystal defects. Through TEM, researchers can gain a deeper understanding of the internal structure of materials, thereby evaluating their properties and potential applications.

​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.

Particle size analysis is a technique used to study the size distribution of particles in a sample. It is a vital analysis technique in many industries, such as pharmaceuticals, food, chemical, and environmental due to the importance of controlling particle size for the product's performance. However, the accuracy of the particle size analysis results depends significantly on the instrument's precision and how well the sample preparation and measurement process is executed. In this blog post, we will discuss the factors that can affect the accuracy of particle size analysis.

Surface hydroxyl engineering refers to the targeted regulation of the number, distribution, and chemical activity of hydroxyl (- OH) groups on the surface of materials through physical, chemical, or plasmonic means, in order to achieve precise adjustment of surface properties. Hydroxyl groups are the most common polar functional groups that can form hydrogen bonds, coordination bonds, or covalent bonds with water, metal ions, polymer chains, or biomolecules, significantly altering the hydrophilicity, surface energy, adsorption/catalytic activity, and biocompatibility of materials.
