SUGGESTED READING Electrospinning has been applied to prepare uniaxially aligned nanofibers made of organic polymers, ceramics, and polymer/ceramic composites. Special, unique and multifunctional properties arising due to the dispersion of nanoparticles in ceramic and metal matrix are briefly discussed followed by a classification of resulting aerospace applications.

Used polymer and ceramic insulators were collected from the scrapyard of an electric utility company in São Paulo, and new insulators of the same model from the company's warehouse. If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size, we can observe that the metal ball is heavier than the plastic ball. short courses within the context of its existing You're looking at OpenBook, NAP.edu's online reading room since 1999.
