  • Regenerative Polymeric Coatings Enabled by Pressure Responsive Surface Valves
    Advanced Engineering Materials, 2017
    Co-Authors: Ryan C. R. Gergely, Nancy R Sottos, Scott R White
    Abstract:

    Protective coatings safeguard the underlying substrate material from environmental attack and are critical for operating in harsh conditions. Self-healing materials have been developed for the autonomous repair of damage in coatings. This work demonstrates a regenerative coating system that is a simplified synthetic analog of skin. A protective UV curable coating reforms with properties identical to the native coating after complete removal. An integrated Surface Valve prevents premature curing of healing agent contained within a vascular substrate prior to damage-triggered release, facilitating recovery from repeat damage. The protective coating reforms when exposed to simulated sunlight.

  • Design of Hydraulic High-Speed Switch Valve Spool Based on GMA
    2014
    Co-Authors: Zhang Yuan-she
    Abstract:

    How to solve the contradiction between large flow and high response remains to be a difficult problem in the design of hydraulic high-speed switch Valve,for the achievement of high flow of the traditional hydraulic Valve means increasing the diameter and stroke of the Valve spool,which consequently lengthens response time.The giant magnetostrictive actuator(GMA)in place of the traditional proportional electromagnet structure can be adopted to obtain higher response rate and larger output through electrical-mechanical conversion,but because of the characteristics of giant magnetostrictive material,the output displacement is very small,which limits the flow of the Valve.Therefore,a multi-way stream Surface Valve spool was designed on the basis of repeated modeling to achieve both larger flow and higher response of the spool.The comparative analysis showed that the flow of multi-way stream Surface spool was 1.8times than that of the conventional cone Valve when the Valve spool was of the same size and working condition.

  • A pneumatically operated, submersible, 3-dimensional water sampler for microscale studies
    Limnology and Oceanography-methods, 2006
    Co-Authors: Laurent Seuront, Dominique Menu
    Abstract:

    To determine how marine microorganisms locally interact, it is critical to assess their 3-dimensional distribution with microscale spatial sampling resolution and minimal disturbance. Here we describe a 3-dimensional syringe pump water sampling device that overcomes the constraints of previous 1- or 2-dimensional samplers. 3DMAPPER consists of a 1-m3 cubic stainless-steel structure supporting three 10-by-10 arrays of 60-mL syringes with an intersample distance of 5 cm. The design ensures a high stability of syringe sampling position and an undisturbed sampling volume for mean flow velocities ranging from 5 to 180 cm s−1. 3DMAPPER can easily be disassembled into subsections to simplify the handling of multiple samples, the syringes are easy to replace, and the sampling of multiple large volumes allows statistical treatment of multiple variables. The 300 syringes of 3DMAPPER are drained under water by increasing the ambient hydrostatic pressure using a SCUBA tank, and simultaneously and immediately filled upon relieving the inside pressure via a Surface Valve. 3DMAPPER is independent of a Surface power supply and is deployed directly in the water to be sampled, making it versatile and appropriate for in situ deployment.
