One central goal in the emerging, but already very broad, field of nanoscience and nanotechnology is the desire to understand, and eventually control, the structure and properties of materials at the nanometre size scale.  This research program will investigate structure and properties of materials with nano-scale features, with a view to applications in micro-devices such as sensors and catalysis, and in the longer term, exploring potential applications for biomedical devices and energy storage and conversion.  Work by this researcher and his collaborators has laid some of the groundwork for these studies in recent years and is an ongoing topic of interest.  This work has shown that by combining novel, nano-porous thin film materials with chemical functionalisation techniques, a high degree of control over both structural and surface properties can be achieved. The level of control afforded by the thin film deposition process over the morphology of these nanostructured materials is complemented by the fact that it should be possible to attach nearly any desired chemical functional group to the surface.  This will allow the derivatised material to be tuned both structurally and chemically to the specific application.  For instance, an optical filter based on our porous films needs to be desensitised to changes in humidity for optimal environmental stability.  On the other hand, if we want to create integrated humidity sensors, we need to improve the sensitivity of the device toward water vapour.  With control over both morphology and surface chemistry, we will be better able to accomplish our goals of functional nano-materials and devices.

纳米科学和纳米技术的一个核心目标是在纳米尺度上理解并最终控制材料的结构和性质。该研究计划将研究具有纳米尺度特征的材料的结构和性质，以期在传感器和催化等微型器件中应用，并从长远来看，探索生物医学设备和能量储存和转换的潜在应用。这位研究人员及其合作者的工作为近年来的这些研究奠定了一些基础，并且是一个持续的兴趣话题。这项工作表明，通过将新型纳米多孔薄膜材料与化学功能化技术相结合，可以实现对结构和表面性能的高度控制。薄膜沉积工艺对这些纳米结构材料的形态提供的控制水平通过以下事实得到补充，即几乎可以将任何所需的化学官能团连接到表面。这将允许衍生化材料在结构和化学上都针对特定应用进行调整。例如，基于我们的多孔薄膜的滤光片需要对湿度变化不敏感，以获得最佳的环境稳定性。另一方面，如果我们想制造集成湿度传感器，我们需要提高器件对水蒸气的敏感性。通过对形貌和表面化学的控制，我们将能够更好地实现功能性纳米材料和器件的目标。
