20150063739 | Actively Tunable Polar-Dielectric Optical Devices - Optical devices that include one or more structures fabricated from polar-dielectric materials that exhibit surface phonon polaritons (SPhPs), where the SPhPs alter the optical properties of the structure. The optical properties lent to these structures by the SPhPs are altered by introducing charge carriers directly into the structures. The carriers can be introduced into these structures, and the carrier concentration thereby controlled, through optical pumping or the application of an appropriate electrical bias. | 03-05-2015 |
20130323777 | Compact Multifunctional Ligand to Enhance Colloidal Stability of Nanoparticles - A ligand design allows compact nanoparticle materials, such as quantum dots (QDs), with excellent colloidal stability over a wide range of pH and under high salt concentrations. Self-assembled biomolecular conjugates with QDs can be obtained which are stable in biological environments. Energy transfer with these ligands is maximized by minimizing distances between QDs/nanoparticles and donors/acceptors directly attached to the ligands or assembled on their surfaces. | 12-05-2013 |
20130011459 | Composite for Controleed Release of Small Molecules in Aquatic Environments - A composite material formulated for slow release of a small molecule in seawater includes a porous inorganic oxide framework and micelles embedded within the pores of the framework. The micelles include a surfactant and a small molecule, the surfactant being present in the composite material at no more than 80 parts by weight per 100 parts by weight inorganic oxide, the composite material being stable in seawater for releasing the small molecule over at least 20 days. | 01-10-2013 |
20120138152 | Tubular Array for Fluidic Focusing with Integrated Optical Access Region - An apparatus for creating sheathed flow includes an inlet section comprising an array of tubes including at least one sheath inlet port and a sample inlet port, a flow focusing section downstream from the inlet section, an optical access section downstream from the flow focusing region and comprising opposing flat surfaces, and an outlet section downstream from the optical access section, wherein the apparatus is operable to create a sheathed flow around a fluid introduced into the sample inlet port and to maintain the sheathed flow through the optical access section. Applications of the apparatus and method include bead/particle counting, flow cytometry, waveguiding, and fluid control. | 06-07-2012 |
