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.

The reactivity of an element is significantly influenced by the number of electrons in its group shell. Elements with a nearly complete group shell tend to be more reactive as they seek to either gain or lose electrons to achieve a stable electronic configuration. This is why metals, which often have one or two electrons in their group shell, readily donate them, while nonmetals, with five or six electrons in their group shell, tend to gain electrons to complete their shell.

  • In today's fast-paced world, groupthink and fan culture have become increasingly intertwined.

On the other hand, fan culture, which refers to the shared interests, values, and behaviors among fans of a particular celebrity, movie, or TV show, has also grown exponentially in recent years.
