book coverIs That Real? Identification and Assessment of the Counterfeiting Threat for U.S. Banknotes   (BMED)
Released 2006-04-19

A key mission of the Bureau of Engraving and Printing of the Department of the Treasury is the design and printing of U.S. banknotes. The BEP is responsible for producing easily recognizable currency that is difficult to counterfeit. In recent years, the bureau has recognized the modern information technology could lead to entirely new types of counterfeiting threats, and it has requested a number of studies by the NRC to assess these evolving threats. In this new request, the BEP asked the NRC to identify and evaluate significant emerging counterfeiting threats and to assess technologically feasible counterfeit-deterrent features for potential use in new designs. This first report provides an assessment of emerging threats including a wide range of digital imaging and printing techniques. It also presents an analysis of a systems approach to the counterfeiting threat. The second report will offer an evaluation of new banknote features to address these threats.

book coverProceedings from the Workshop on Biomedical Materials at the Edge:Challenges in the Convergence of Technologies   (NMAB)
Released 0000-00-00

Recent advances in biomedical materials technology hold the promise of a revolution in clinical medicine. These advances are being made possible by a convergence of technologies arising from a wide array of scientific discoveries. This convergence, however, is presenting new challenges as well as new opportunities. To explore these findings and to discuss possible ways to overcome the challenges, a workshop on this topic was held under the auspices of the NRC's Roundtable on Biomedical Engineering Materials and Applications. This report and accompanying CD provides a summary and the proceedings of the workshop. They present discussions of the context for new biomedical materials and of the three emerging technologies that were covered at the workshop: stem cells as biomaterials of the future, biomolecular materials composites, and superamolecular/nanoscale engineering and design.
