20120322162 | GENERATION OF MONODISPERSE DROPLETS BY SHAPE-INDUCED SHEAR AND INTERFACIAL CONTROLLED FUSION OF INDIVIDUAL DROPLETS ON-DEMAND - A microfluidic device for generation of monodisperse droplets and initiating a chemical reaction is provided. The microfluidic device includes a first input microchannel having a first dimension and including a first phase located therein. The device also includes a second input microchannel having a second dimension and including a second phase located therein. In accordance with the present disclosure, the second dimension is different from the first dimension and the first phase is immiscible in the second phase. A microchannel junction is also present and is in communication with the first input microchannel and the second input microchannel. The device further includes an output channel in communication with the microchannel junction and set to receive a monodisperse droplet. In the present disclosure, the difference in the first dimension and the second dimension creates an interfacial tension induced force at the microchannel junction which forms the monodisperse droplet. | 12-20-2012 |
20130115413 | FABRICATION AND USE OF ELEVATED OPTICAL NANOANTENNAS - A nanostructure including a pair of pointed metallic tips in proximity to each other. The pair of pointed metallic tips protrudes from a planar top surface of a substrate by a pair of pillar structures. The pair of pointed metallic tips can enhance optical scattering of materials placed therebetween through plasmonic electromagnetic field effects induced by the proximity of the pair of pointed metallic tips. Perturbation or interference from the substrate can be minimized through the increased distance from the substrate. The pair of pointed metallic tips can be formed by patterning a pair of adhesion material portions on a substrate, by vertically and laterally recessing regions that are not covered by the adhesion material portions, and by depositing a metal on the pair of adhesion material portions. | 05-09-2013 |
20140093572 | ACTIVE MATERIALS FOR PREVENTION AND TREATMENT OF FOULED SURFACES - A method, composition and structure to treat fouling. In one embodiment, the method of treating fouling includes providing a structure including a first component of a base material and a second component of an energetically activated nanostructure, and applying a stimuli to the structure that effectuates an increase or decrease in the temperature of the energetically activated nanostructure. The increase or decrease in the temperature of the energetically activated nanostructure modifies the chemical and/or mechanical properties of the base material. The modifications to the chemical and/or mechanical properties of the base material obstruct fouling of the structure. | 04-03-2014 |
20150044092 | LOCAL THERMAL ACTUATION OF MATERIAL SURFACES VIA MICRO- AND NANOWIRE HEATING FOR THE PREVENTION OF CELLULAR ATTACHMENT AND BIOLOGICAL FOULING - The invention relates in various embodiments to a composite useful as e.g. a medical implant device, and a method of treating fouling, including biofouling as may occur on an implant. The composite comprises a matrix phase and a patterned phase that comprises an energetically activatable wire intermixed with the matrix phase, the wire when energetically activated, which includes thermal activation, causes modification of at least a portion of the matrix phase to treat fouling that might otherwise occur. The method of treating biofouling may be practiced on a patent while the medical implant of the invention is in situ. | 02-12-2015 |
