The physical vibrations produced by jackhammers can have lasting effects on the surrounding structures and ground, potentially causing cracks in walls and foundations. This collateral damage may necessitate additional repairs, adding unforeseen costs to the project. Furthermore, the dust and debris generated during the demolition process pose health risks to both workers and nearby communities, requiring rigorous dust control measures and protective gear.

The polymerization of resin monomers was initiated in the presence of nanofibers as structural templates to prepare a hydrogel with nanofibrous networks, followed by the drying and pyrolysis to get hard carbon aerogel. During polymerization, the monomers deposit on templates and weld the fiber-fiber joints, leaving a random network structure with massive robust joints. Moreover, physical properties (such as diameters of nanofiber, densities of aerogels, and mechanical properties) can be controlled by simply tuning templates and the amount of raw materials.
