The primary advantage of using an extension rod lies in its ability to extend the drilling depth without compromising on the torque and power transmission. This is particularly crucial in deep excavation projects, tunneling, and large-scale construction works where reaching substantial depths is a necessity. The extension rods allow drillers to penetrate further into the earth's crust, facilitating the extraction of minerals, installation of anchoring systems, or creation of underground infrastructure.

In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.
