It is durable and robust while also being easy to transport as it is lightweight. Because it is so durable, it can withstand winds and exposure to harsh elements without damage.
- Furthermore, portable drills are available in a range of sizes and power levels, allowing you to choose the model that best suits your needs. From compact drills that are perfect for light-duty tasks to more powerful models that can handle heavy-duty construction work, there is a portable drill for every job.



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.
