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.

The development of the air rock drill has not been without its challenges. Ensuring that the device is both powerful and precise requires sophisticated engineering. The seals must be durable enough to withstand the high-pressure environment while maintaining an airtight grip to prevent any loss of pressure. Furthermore, the design must account for vibration and recoil, ensuring that the tool does not damage itself or fatigue the user during extended periods of operation.
