Silica Nanoparticles - UnderstandingNano

Silica Nanoparticles. Silica, or silicon dioxide, is the same material used to make glass. In nature, silica makes up quartz and the sand you walk on at the beach. Unlike metals such as gold and iron, silica is a poor conductor of both electrons and heat. Despite these limitations, silica (silicon oxide) nanoparticles form the framework of silica aerogels. Silica aerogels are composed of ...
