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.

A hexagonal drill rod, as the name suggests, features a hexagonal cross-section rather than the conventional circular one found in standard drill rods. This design alteration is not merely aesthetic; it serves a functional purpose that significantly enhances performance. The hexagonal configuration provides greater surface area, which in turn increases the contact area between the rod and the drilling machine. This results in better torque transfer, reducing slippage and enhancing overall drilling stability.
