Ironing Out the Origins of Wrinkles, Creases and Folds
July 17, 2013
Engineers at Brown University have mapped out the amounts of compression required to cause wrinkles, creases and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which could be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
