One of the primary industries that rely on rock button bits is the mining industry. Mining companies use these specialized drill bits to extract minerals and ores from deep within the earth. The rock button bit is capable of drilling through hard rock formations, allowing miners to access valuable resources that would otherwise be inaccessible. Without the use of rock button bits, mining operations would be significantly slowed down, leading to lower productivity and profitability.

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.
