The hard carbon aerogel can maintain the super-elasticity in harsh conditions, such as in liquid nitrogen. Based on the fascinating mechanical properties, this hard carbon aerogel has promise in the application of stress sensors with high stability and wide detective range (50 KPa), as well as stretchable or bendable conductors. This approach holds promise to be extended to make other non-carbon based composite nanofibers and provides a promising way of transforming rigid materials into elastic or flexible materials by designing the nanofibrous microstructures.

A Jack Hammer Drilling Rod, also known as a percussion drill rod, is essentially a high-strength steel shaft that connects the drill chuck to the power source. Its primary function is to transfer the mechanical energy generated by the jackhammer into the drill bit, enabling it to break through tough surfaces with precision and efficiency. The name 'jack hammer' itself derives from its action, which mimics the rapid up-and-down motion of a blacksmith's hammer.
