Research on the structural design and performance optimization of nanomaterials in materials science and engineering

This paper deeply studied the structural design and performance optimization of silver nanoparticles. Through carefully designed experiments and molecular dynamics simulations, the paper revealed the significant effects of different structural properties on their electrical, optical and catalytic properties. In the experimental part, silver nanoparticles of different sizes and shapes were first synthesized and their structural properties were characterized in detail. The results show that smaller silver nanoparticles exhibit higher conductivity, while changes in shape significantly affect the optical absorption properties of the particles, especially in the regulation of the position of the surface plasmon resonance peak. In addition, by adjusting the surface modification of the particles, their activity in catalytic reactions was optimized, among which the efficiency of silver nanoparticles with specific surface modifications in specific catalytic reactions was increased by about 40%. Molecular dynamics simulations further support these experimental findings, showing how subtle changes in particle structure and surface state affect their overall performance.
