Thermal and Mechanical Response of POSS coated Nanophased expandable foam core materials

Jones W.D., Rangari V.K., Jeelani S., Tuskegee University, US

A sonochemical technique has been established to coat variations of POSS nanoparticles on expandable microspheres. Thermal analyses results indicate that there is an increase in thermal stability of nanophased foam as compared to the neat [...]

Plasma Treatment of Nanofillers for Polymer Nanocomposites

Ritts A.C., Yu Q., Li H., University of Missouri-Columbia, US

Nanofillers were functionalized with amine groups using low-temperature plasma to enhance dispersion and interfacial tension with Epon 815C resin. The amine groups remained on the coating surface were anticipated to strengthen the interfacial interactions through [...]

Nanotechnology for Building Security

Elvin G., Green Technology Forum, US

Despite increased vigilance and annual federal anti-terrorism spending in excess of $55 billion, building security remains a major concern for most Americans. For those working in large governmental or institutional buildings, fears are particularly acute. [...]

Nanoporous Alumina Membranes Based Microdevices for Ultrasensitive Protein Detection

Bothara M.G., Reddy R.K., Barrett T., Carruthers J., Prasad S., Portland State University, US

This research focuses on using the electrical and chemical properties of nanoporous alumina membranes to improve the sensitivity and performance of Si-based microdevices for protein sensing. The integration of nanoporous membranes with the microdevice results [...]

Interaction of Polyamido-amine (PAMAM) nanoparticles with the glassy carbon supported bilayer lipid membrane

Jadhav S.R., Mark Worden R., Michigan State University, US

Polyamido-amine (PAMAM) dendrimers are hyperbranched polymers with uniform particle size making them ideal monodisperse nanoparticles. PAMAM dendrimers are being pursued as non-viral vectors for gene delivery due to their low immunogenicity and their ability to [...]

Permeability and protein separations: functional studies of porous nanocrystalline silicon membranes

Snyder J., Kavalenka M., Fang D., Striemer C., Fauchet P., McGrath J., University of Rochester, US

We have developed an ultrathin (15nm) freestanding nanoporous silicon based membrane [1]. This new material, termed porous nanocrystalline silicon (pnc-Si), is fabricated using standard photolithography techniques. Pore sizes can be tuned in a thermodynamically driven [...]

Effects of the Building Block on the Morphology and Properties of Porous CdSe Nanostructured Framework

Yu H., Bellair R., Kannan R., Brock S., Wayne State University, US

A major challenge in designing and making potentially valuable nanostructures is to find suitable ways to effectively tune their properties and function. Recent work in our lab has demonstrated a powerful strategy to engineer the [...]

Mechanical and magnetic properties comparison between elastomer composites based on nickel nanoparticles and nanowires as fillers

Denver H., Martin E., Gupta A., Heiman T., Gupta A., Borca-Tasciuc D-A., Rensselaer Polytechnic Institute, US

Applications that utilize magnetic polymer nanocomposites are currently emerging at a high rate. Examples include magnetic actuation in microelectromechanical systems (MEMS) and medical devices, thermal actuation through electromagnetic power harvesting, and magnetically actuated morphing structures. [...]

Fabrication and Characterization of Nanoscale Heating Sources (“Nanoheaters”) for Nanomanufacturing

Jogdand H., Gulsoy G., Ando T., Chen J., Doumanidis C.C., Gu Z., Gulsoy G., Rebholz C., Wong P., University of Massachusetts-Lowell, US

In macroscale manufacturing, active use of heat to alter the geometry, structure and properties of solids is central to material removal, deposition, joining, shaping, and transformation processes. However, traditional heat sources encroach difficulties with fine [...]

Autonomous Nanoscale Motion Through Catalysis

Sen A., Pennsylvania State University, US

Nanoscale moving systems are currently the subject of intense interest due in part to their potential applications in nanomachinery, nanoscale assembly, robotics, tribology, fluidics, and chemical/biochemical sensing. Most of the research in this area has [...]
