carbide conical button bits designed for efficient rock drilling ...

The environmental cost is perhaps the most troubling long-term expense associated with jackhammer use. The emissions from fuel-powered jackhammers contribute to air pollution, while the waste generated from demolition activities often ends up in landfills, exacerbating the solid waste crisis. Increasingly, construction firms are exploring more sustainable options, such as dustless blasting technologies and recycling programs, to mitigate these environmental impacts.

Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
