Brookhaven Lab physicists Aaron Stein and Kevin Yager discuss their directed self-assembly technique that enables different molecular patterns—in this case, parallel lines and dots—to coexist within a single nanostructure in specific arrangements. The ability to direct the self-assembly of materials into complex nanostructures could enable advances in microelectronics, sensing, and other applications.
Kevin Yager begins the 513th Brookhaven Lecture with a brief introduction to the nanoscale—the tiny world within our own where elements are so small they are measured in billionths of a meter. Yager then discusses the light-based techniques and laser tools he has developed to arrange molecules into ordered patterns and specific shapes to fabricate more perfect, complex nanostructures.
During the 507th Brookhaven Lecture, Dong Su explains how he and his colleagues are using advanced tools at the Center for Functional Nanomaterials at Brookhaven Lab to study materials and determine how different atomic-level structures can improve performance for rechargeable batteries.
Scientists from all over the world visit the Center for Functional Nanomaterials to explore strange phenomena hidden on the nanoscale—an exciting and powerful landscape spanning just billionths of a meter. The U.S. Department of Energy opened the CFN, one of its five nanoscale science research centers in the United States, to develop unprecedented energy technologies and solve fundamental scientific puzzles.
Kevin Yager, a scientist at Brookhaven Lab's Center for Functional Nanomaterials, discusses his research on materials spanning just billionths of a meter. Yager specializes in making new materials through meticulously guided self-assembly and probing nanoscale structures with a technique called x-ray scattering.
In the 474th Brookhaven Lecture Oleg Gang discusses how Brookhaven scientists have devised a way of using strands of synthetic DNA attached to the surface of nanoparticles to instruct them to self-assemble into nanoscale structures, clusters, and three-dimensional organizations.
A novel multimodal optical nanoprobe is incorporated into a transmission electron microscope (TEM) sample holder. The nanoprobe allows scientists to perform all the usual experiments done in a TEM in addition to those involving optical excitation and measurement of the sample, electrical measurements on the sample, scanning tunneling microscopy (STM), and combinations of these measurements. Of particular utility is the ability to simultaneously measure optical and electrical properties of the sample at the nanoscale.
Building on the idea of using DNA to link up nanoparticles scientists at Brookhaven National Lab have designed a molecular assembly line for high-precision nano-construction. Nanofabrication is essential for exploiting the unique properties of nanoparticles in applications such as biological sensors and devices for converting sunlight to electricity.
Staff from Brookhaven's new Center for Functional Nanomaterials (CFN) describe how this advanced facility will focus on the development and understanding of nanoscale materials. The CFN provides state-of-the-art capabilities for the fabrication and study of nanoscale materials, with an emphasis on atomic-level tailoring to achieve desired properties and functions. The overarching scientific theme of the CFN is the development and understanding of nanoscale materials that address the Nation's challenges in energy security.
The Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory explores the unique properties of materials and processes at the nanoscale. The CFN is a user-oriented research center, with the double mission of being an open facility for the nanoscience research community and advancing the science of nanomaterials that address the nation's energy challenges.
One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit applied science and technology organization.
