DNA/Cellulose hybrid nanomaterials

Mangalam A., Simonsen J., Benight A.S., Oregon State University, US

One potential advantage of nanotechnology is the ability to engineer bottom-up hierarchical assembly of nanoparticles into functional macroscale materials and devices. The most promising mechanism for accomplishing this is self-assembly. In this project, an advanced [...]

Unique Roles of DNA Wrapped SWNTs: In-situ Fabrication of Self-Doped Polyaniline Nanocomposites

Ma Y.F., Ali S.R., He H.X., Rutgers University, US

Inspired by the remarkable electrical conductivity, the superior mechanical properties of carbon nanotubes(CNTs), and the rich optical, electrical and electrochemical properties of conducting polymers, nanocomposites of conducting polymers and CNTs have been pursued with a [...]

Elastomeric Composites to Reduce the Effects of Trunnion Mode in Inertial Devices

Perez Ma., Shkel A.M., University of California Irvine, US

Composites have long been known for their ability to combine the properties of dissimilar materials to create properties ideally tailored for an application. We propose applying these features to MEMS in order to reduce the [...]

Development of a Biologically Enhanced Carbon Nanotube Based Composite

Parker R., O’Neal R., Fisher D., Davey Kirk, Liang R., Edwards J., Florida A&M University, US

Composite materials continue to be important to the evolution of human space flight activity. The low weight/high strength ratio and thermal properties of carbon based composite materials in particular that make them well suited for [...]

Carbon Nanofiber Reinforced Carbon/Polymer Composites

Joshi M., Bhattacharyya A., Indian Institute of Technology, IN

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The [...]

Noncovalent Engineering of Carbon Nanotube Surfaces

Chen J., Ramasubramaniam R., Liu H., Zyvex Corporation, US

Single-walled carbon nanotubes (SWNTs), due to their novel structural, thermal, electrical, mechanical and optical properties, are expected to find applications in many fields. Pristine SWNTs are generally insoluble in common solvents, and difficult to functionalize [...]

A Nanoscale Composite Material for Enhanced Damage Tolerance in MEMS Applications

Paranjpye A., MacDonald N.C., Beltz G.E., university of california, santa barbara, US

A two-dimensional laminar composite material has been shown to exhibit enhanced damage tolerance due to zones of residual compressive stress. The damage tolerance appears as a threshold stress below which the structure does not fail [...]

Preparation of Monodispersed Silica and Composite Spheres

Tang F., Ding J., Chen D., Huang Z., Xia H., Meng X., The Chinese Academy of Sciences, CN

Nanoscale crystallites of metals or semiconductors, exhibiting unusual size-dependent electronic, magnetic, optical, and catalytic properties due to the onset of quantum effects, are being heralded as the next-generation building blocks for modern materials design. However, [...]
