Two simple building blocks produce complex 3-D material

Mon, 22 May 2017 00:00:00 EDT

(Northwestern University) Northwestern University scientists have built a structurally complex material from two simple building blocks that is the lowest-density metal-organic framework ever made. Directed by design rules developed by the scientists, uranium atoms and organic linkers self-assemble into a beautiful crystal -- a large, airy 3-D net of very roomy and useful pores. The pores are so roomy, in fact, that the scientists have nestled a large enzyme inside a pore -- no small feat.



The Optical Society commemorates the rich tradition and history of Optics Letters
