Creating Nano-Structures from the Bottom Up
April 24, 2012
The traditional method for creating man-made crystals is described as "top-down," which means they are fashioned by lithography or molding techniques and can't be easily created in three dimensions. A new "bottom up" approach involves coaxing microscopic particles to assemble themselves into larger crystalline structures using other microscopic particles and magnetic fields.
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) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
