Nonetheless, the gasoline-powered rock drill remains a vital tool in many industries, a symbol of the evolution of drilling technology. Its contribution to the extraction of minerals, the construction of infrastructure, and the advancement of civilization cannot be overstated. As we continue to innovate and develop new technologies, the legacy of the gasoline-powered rock drill serves as a reminder of the power of human creativity and our relentless pursuit of efficiency.
The polymerization of resin monomers was initiated in the presence of nanofibers as structural templates to prepare a hydrogel with nanofibrous networks, followed by the drying and pyrolysis to get hard carbon aerogel. During polymerization, the monomers deposit on templates and weld the fiber-fiber joints, leaving a random network structure with massive robust joints. Moreover, physical properties (such as diameters of nanofiber, densities of aerogels, and mechanical properties) can be controlled by simply tuning templates and the amount of raw materials.
