The term rotary in rotary jack hammer refers to the unique mechanism of this tool. Unlike a traditional hammer that delivers a linear blow, a rotary jack hammer delivers a circular motion combined with a forward thrust, multiplying the force exerted on the work surface. This rotation-to-punch action makes it highly effective for heavy-duty tasks, such as breaking up concrete slabs, removing tile, or excavating for foundations.

A marble drill bit is a specialized cutting tool specifically designed to perforate through the hard and dense surface of marble. Unlike regular drill bits that might struggle or damage the marble, these bits are engineered with precision to deliver clean, accurate, and chip-free holes. They typically feature tungsten carbide tips or diamond-coated surfaces, materials known for their exceptional hardness and resistance to wear, ensuring a smooth and efficient drilling process.

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.
