20120073027 | Elastomeric Composites with Tether-Containing, Conducting Polymers for Nanoscale Diffusion Control - A redox-active conductive polymer includes a charged tether. An interpenetrating network including such a conducting polymer can be switched between two states of diffusivity (porosity) by application of a voltage. Such a material can be useful in breathable protective clothing, controlled release, intelligent sensing/filtration, novel separation processes, nanomanufacturing, and other areas. | 03-29-2012 |
20120175529 | Photoresponsive Nanoparticles as Light-Driven Nanoscale Actuators - Photoresponsive shape memory nanoparticles have a layered smectic ordering and include a photoresponsive moiety selected from the group consisting of azobenzene, stilbene, and spiropyran. Multiple cycles of contraction and extension in these materials can be controlled by UV and visible light. By changing light intensity and exposure time, the magnitude of actuation can be modulated. | 07-12-2012 |
20130181171 | Metamaterial Optical Elements Self-Assembled on Protein Scaffolds - Protein scaffolds from tobacco mosaic virus coat protein modified to incorporate polyhistidine can bind to a metal or a dye while having improved self-assembly characteristics. The scaffold can take the form of tubes or disks, and can further be formed into dual plasmonic ring resonators. Such self-assembled structures provide useful optical properties. | 07-18-2013 |
20130213265 | Self-Assembly of Metallic Nanoparticles Into Macroscopic, High-Density, Monolayer Films - A method of forming a monolayer film of nanoparticles includes forming a fluid mixture by combining nanoparticles dispersed in water with a water-miscible organic solvent and a molecular ligand comprising a head group with affinity for the nanoparticle, and introducing the fluid mixture to a substrate in the presence of an air/fluid interface, thereby causing a monolayer film of nanoparticles to form on the substrate. Such monolayers films can include metallic nanoparticles such as gold, and possess substantially uniform spacing over at least a one centimeter length scale. | 08-22-2013 |
20130334475 | Photoresponsive Nanoparticles as Light-Driven Nanoscale Actuators - Photoresponsive shape memory nanoparticles have a layered smectic ordering and include a photoresponsive moiety selected from the group consisting of azobenzene, stilbene, and spiropyran.
