  • Patent number: 8906285
    Abstract: An stable electrohydrodynamic filament is obtained by causing a straight electrohydrodynamic filament formed from a liquid to emerge from a Taylor cone, the filament having a diameter of from 10 nm to 100 ?m. Such filaments are useful in electrohydrodynamic printing and manufacturing techniques and their application in liquid drop/particle and fiber production, colloidal deployment and assembly, and composite materials processing.

  • Patent number: 8153062
    Abstract: Electrochemical devices, methods, and systems for detecting and quantifying analytes are disclosed. A chemical detection reagent is locally generated in a test solution by electrochemical reaction of a precursor compound caused to migrate into the test solution from a precursor solution separated from the test solution by a cell separator. This approach provides precise metering of the reagent, via the charge passed, and avoids the need to store a reagent solution that may be chemically unstable. In one embodiment, the starch concentration in a colloidal solution can be measured via spectroscopic detection of a blue complex formed by the interaction of starch with iodine produced, on demand, by electrochemical oxidation of iodide ion. The approach may also be used to characterize certain types of analytes. The invention is amenable to automation and is particularly useful for on-line monitoring of production processes, including the inclusion of feed back loop mechanisms for process control.

  • Patent number: 8076820
    Abstract: An electro-osmotic pump includes a pump chamber having a wall fabricated of an electric double layer material, the surface area of the electric double layer material being high relative to the volume of the chamber. An electric potential applied across the material causes a fluid in the chamber to be transported through the wall. A nastic actuator includes the electro-osmotic pump and an actuator chamber, having a variable volume, coupled to the pump chamber. A superabsorbent polymer is disposed in the pump and actuator chambers, such that transport of the fluid into the pump chamber results in absorption of the fluid by the superabsorbent polymer, causing the actuator chamber to increase in volume. When the electric potential is applied across the superabsorbent polymer, the superabsorbent polymer expands, further causing the actuator chamber to increase in volume.
