Applied interfacial technology

我的发现计划专注于设计更快速的跨气-液-固界面的质量和能量传输，以提高能源效率。对于电化学系统，研究了通过金属表面阻挡层的固态离子和电阻，从金属表面阻挡层到溶液相物质(通常是气态)的电子转移阻力，以及这些物质通过液体边界层的传输。研究表明，对于许多体系，需要额外考虑介观结构的影响，如催化剂或活性电极的大小、比表面积效应和孔大小。这项研究同样适用于化学体系，忽略了电化学驱动力。 所采取的方法是通过实验确定给定系统的主要变量，以便对影响进行建模，然后通过修改系统以增强速率确定步骤来进行验证。这些知识随后被用于技术开发的应用领域。使用的分析工具包括电化学技术(静态和动态极化，包括EIS)、元素和形态的表面分析(XPS、SEM/EDX、X射线衍射、TGA/DTA/MS)和溶液和气相分析(GC/LC/MS)。 在下一个发现期，基础发现金研究将支持的应用领域包括：通过电化学氧化清洁水；增加超级电容器的储能；以及增强活性碳污染物去除。

My Discovery Program focuses on engineering more rapid transport of mass and energy across gas-liquid-solid interfacial boundaries in order to improve energy efficiency. For electrochemical systems, the research investigates the solid state ionic and electrical resistance through the metal surface barrier layers, the electron transfer resistance from the layer to the solution phase species (often gaseous) and the transport of these species through the liquid boundary layer. The research has shown that for many systems, additional consideration is needed for meso-scale structural influences such as, catalyst or active electrode size, surface area effects and pore size. This research is equally relevant to chemical systems, ignoring the electrochemical driving forces. The approach taken is to experimentally determine the dominant variables for a given system in order to model the effects and then to verify by modifying the system to enhance the rate determining step. This knowledge is then used in application areas for technology development . The analytical tools used include electrochemical techniques (static and dynamic polarizations including EIS), analysis of surfaces for elements and speciation (XPS, SEM/EDX, XRD, TGA/DTA/MS) and solution and gas phase analysis (GC/LC/MS). For this next Discovery period the application areas which will be supported by the fundamental Discovery Grant research are: Clean water via Electrochemical Oxidation; Increased Energy Storage in Supercapacitors; and Enhanced Activated Carbon Contaminant Removal.
