Preparation of Transmission Electron Microscopy (TEM) Samples
The preparation of Transmission Electron Microscopy (TEM) samples involves sample preparation techniques, sample staining, and sample mounting. Sample preparation techniques mainly include mechanical grinding, ultrasonic treatment, and ion beam etching. Sample staining typically employs heavy metal staining (such as uranium and lead) for positive staining, or uses negative staining and immunolabeling techniques. During sample mounting, commonly used support materials include carbon films and metal grids, with considerations for sample fixation methods to ensure stability.

- Biological study on anti-aging of membrane proteins in cell lines
This study focuses on the biological research of anti-aging of membrane proteins in cell lines, covering the selection of experimental cell lines (including human cell lines and model organism cell lines), employing various anti-aging interventions such as gene editing, drug therapy, and nutritional intervention, and assessing the degree of aging by detecting aging biomarkers such as telomere length, protein carbonyl levels, and ROS levels, aiming to reveal the important role of membrane proteins in the anti-aging process.
- Circular Economy and Chemical Balance
Circular Economy and Chemical Balance focuses on the concepts, principles, and practical cases of circular economy. It also analyzes the principles of mass and energy conservation in chemical reactions, revealing the intrinsic link between circular economy and chemical balance. By optimizing resource utilization and reducing waste emissions, circular economy and chemical balance promote each other, jointly driving sustainable development.
- The influence of pressure on gas reactions
The influence of pressure on gas reactions mainly manifests in changes to the chemical equilibrium position. According to Le Chatelier's principle, increasing pressure typically shifts reactions with a decrease in the number of gas molecules toward the forward direction. The mole concept is crucial in gas reactions, determining the quantities of reactants and products. Additionally, pressure changes have practical implications in industrial production, environmental protection, and energy conversion.
