Ions control shape of nanofibers grown on clear substrate

Researchers from North Carolina State University have found a new way to develop straight carbon nanofibers on a transparent substrate. Growing such nanofiber coatings is important for use in novel biomedical research tools, solar cells, water repellent coatings and others. The technique utilizes a charged chromium grid, and relies on ions to ensure the nanofibers are straight, rather than curling – which limits their utility.
