Highly Efficient Broadband Terahertz Radiation from Metamaterials

Scientists at the U.S. Department of Energy's Ames Laboratory have demonstrated broadband terahertz (THz) wave generation using metamaterials. The discovery may help develop noninvasive imaging and sensing, and make possible THz-speed information communication, processing and storage. The results appeared in the Jan. 8 issue of Nature Communications.

CCI Technical Projects

CYBER SECURITY INTERN:
Intern candidate would assist with the design, implementation, and testing of Perl or Python based components to be used with various cyber security applications. Individual would work with a professional cyber security team with more than ten years of development experience. In addition to structured program development, the individual would learn about intrusion detection and response, automated data analysis, databases, and network programming. Some knowledge of Perl, Python, databases, or general programming techniques is preferred.

Bioengineering Magnets

For a number of animals, including birds, fish and mammals, there is evidence that magnets are used for orientation.  However, little is known about how these organisms build these magnets.  For magnetotactic bacteria we have isolated a protein that will drive the formation of magnetic particles.  We using this protein to discover how these bacteria produce magnets by the process called biomineralization.  

Microfiber Fabrication Process

Engineering 3D biomimetic scaffolds that incorporate both biochemical and mechanical properties required for cell culturing is critical for many biotechnology applications. Hydrogel-based scaffolds are widely used due to their biocompatibility, tunable biochemical properties, and tissue-like water content. In contrast to hydrogels, microfibers have high mechanical strength and are used as the building blocks to create highly porous scaffolds.

Discovery of New Alloys by Bulk Combinatorial Synthesis

The Critical Materials Institute (CMI) is developing new capabilities in the search for new materials or substitutions in existing compounds to reduce or eliminate rare earth elements in energy critical technologies.  We are developing a new method to produce large number of new compounds rapidly using advanced laser processing. While there has been a considerable effort in combinatorial synthesis, there are few efforts in bulk combinatorial synthesis especially for metals.
