  • Publication number: 20160137533
    Abstract: Electrochemical treatment of chromium-containing wastewater has the advantage of simultaneously reducing hexavalent chromium (CrVI) and reversibly adsorbing the trivalent product (CrIII), thereby minimizing the generation of waste for disposal and providing an opportunity for resource reuse. The application of electrochemical treatment of chromium can be often limited by the available electrochemical surface area (ESA) of conventional electrodes with flat surfaces. Here, the preparation and evaluation of carbon nanotube (CNT) electrodes containing of vertically aligned CNT arrays directly grown on stainless steel mesh (SSM). The 3-D organization of CNT arrays increases ESA up to 13 times compared to SSM. The increase of ESA can be correlated with the length of CNTs, consistent with a mechanism of roughness-induced ESA enhancemen, and the increase directly benefits CrVI reduction by proportionally accelerating reduction without compromising the electrode's ability to adsorb CrIII.

  • Publication number: 20150321168
    Abstract: Carbon nanotubes (CNTs) are promising nanomaterials that have the potential to revolutionize water and waste treatment practices in the future. The direct use of unbounded CNTs, however, poses health risks to humans and ecosystems because they are difficult to separate from treated water. Here, we report the design and synthesis of carbon nanotube ponytails (CNPs) by integrating CNTs into micrometer-sized particles, which greatly improves the effectiveness of post-treatment separation using gravitational sedimentation, magnetic attraction, and membrane filtration. We further demonstrate that CNPs can effectively perform major treatment tasks, including adsorption, disinfection, and catalysis. Using model contaminants, such as methylene blue, Escherichia coli, and p-nitrophenol, we show that all the surfaces of individual CNTs in CNPs are accessible during water treatment.

  • Publication number: 20150238746
    Abstract: A frangible connector closure is provided for connection to a medication administration tube, and includes a tubular body portion having an open end configured for being connected to a supply of medication, and an opposite closed end. An elongate, rigid frangible member is disposed at the closed end and closes the end from fluid flow. The frangible member has a closure end and an opposite free end, and a longitudinal axis. In addition, the frangible member extends in an axial direction and has a member transverse dimension. The free end forms a finger portion extending in the axial direction and has a transverse dimension less than the member transverse dimension. The closure end of the frangible member is readily separable from the body portion by manual manipulation relative to the body portion when the frangible member is disposed inside the tube, for user-activated opening of the connector.

  • Publication number: 20150131859
    Abstract: A method and apparatus for tracking an object, and a method and apparatus for calculating object pose information are provided. The method of tracking the object obtains object feature point candidates by using a difference between pixel values of neighboring frames. A template matching process is performed in a predetermined region having the object feature point candidates as the center. Accordingly, it is possible to reduce a processing time needed for the template matching process. The method of tracking the object is robust in terms of sudden changes in lighting and partial occlusion. In addition, it is possible to track the object in real time. In addition, since the pose of the object, the pattern of the object, and the occlusion of the object are determined, detailed information on action patterns of the object can be obtained in real time.
