Laser processing

 Laser processing offers unique advantages as a nanomaterial engineering technique. Unlike conventional fabrication methods that often require vacuum systems or high-temperature environments, laser processing can be performed under ambient conditions without the need for masks, enabling direct and flexible patterning. When applied to nanomaterials, the reduced melting point arising from nanoscale size effects further lowers the energy required for processing, making it both cost-effective and efficient. These strengths position laser processing as a powerful tool for a wide range of applications, including enhancing electrode performance in electronics, fabricating advanced displays, and processing polymers with high precision. By combining scalability, versatility, and efficiency, laser-based approaches provide a promising pathway for next-generation manufacturing technology.

Electrospinning technology

 Electrospinning is a versatile technique for fabricating nanofibers by applying a strong electric field to a polymer solution or melt, which draws ultrafine fibers as the charged jet elongates and solidifies. This simple yet powerful process can produce continuous fibers with diameters down to the nanometer scale, offering exceptionally high surface area, tunable porosity, and structural flexibility. Compared to other nanofabrication methods, electrospinning is cost-effective, scalable, and capable of creating materials with tailored properties for diverse applications. These advantages make it a highly valuable tool for nanomaterial engineering, enabling the development of advanced membranes, sensing platforms, and energy devices that benefit from precisely engineered nanoscale architectures.
