本提案中要求的研究工具和仪器将用于纳米流体的表征和基础研究。纳米流体代表了一种新型的纳米复合流体，在传热、光学和示踪流体方面具有应用。它们由承载纳米颗粒悬浮液的常规流体（例如水、乙二醇）组成，纳米颗粒悬浮液赋予主体流体新的或增强的性质。将使用中红外至近红外范围的傅里叶变换红外（FTIR）光谱仪来测定经处理的主体流体和沉积在纳米颗粒上的稳定化纳米层的化学结构。一个连续波激光器和相关的光学元件将被用来成像的纳米粒子分散在纳米流体和局部流体位移的宏观尺度动态。反过来，这些结果将被用来更好地了解观察到的异常质量/热输运现象与这样的流体。计算机工作站将用于纳米流体动力学的图像处理和计算建模。该部门的其他研究人员将使用FTIR光谱仪来支持他们各自的研究活动：-药品的降解（V. Yargeau教授）：获得代谢产物和降解产物的结构信息。鉴别药物化学和生物降解过程中形成的产物。这些信息将用于改进治疗方法，减少药物在环境中的释放。- 细胞培养工作（R.莱斯克）：验证蛋白质与表面的附着。大多数哺乳动物细胞更喜欢有一个蛋白质的基底膜，以便适当地附着。FTIR光谱法是一种优秀的非破坏性方法，可确保细胞培养前的适当涂层。- 天然气水合物的形成（P. Servio教授）：研究在水溶液中形成的天然气水合物的化学结构。

The research tools and instruments requested in this proposal will be used for the characterization and fundamental study of nanofluids. Nanofluids represent a novel kind of nanocomposite fluids with applications in heat transfer, optics, and as tracer fluids. They consist of regular fluids (e.g. water, ethylene glycol) hosting a suspension of nanoparticles which impart novel or enhanced properties to the host fluids. A mid- to near-IR range Fourier Transform Infrared (FTIR) spectrometer will be used for the determination of the chemical structure of the processed host fluid and stabilization nanolayers deposited onto the nanoparticles. A CW laser and associated optical components will be used to image the macroscale dynamics of nanoparticles dispersed in the nanofluids and local fluid displacements. In turn, these results will be used to gain a better understanding of the anomalous mass/heat transport phenomena observed with such fluids. A computer workstation will be used for the image processing and computational modeling of the nanofluids dynamics. The FTIR spectrometer will be used by other researchers of the department to support their respective research activities: - Degradation of pharmaceuticals products (Prof. V. Yargeau): To obtain structural information on the metabolites and degradation products formed. To identify products formed during chemical and biological degradation of pharmaceuticals. The information will be used to improve the treatment methods and mitigate the release of pharmaceuticals in the environment. - Cell culture work (Prof. R. Leask): To verify protein attachment to surfaces. Most mammalian cells prefer to have a basement membrane of protein for proper attachment. FTIR spectroscopy is an excellent no-destructive way of ensuring proper coating before cell culture. - Gas hydrate formation (Prof. P. Servio): To investigate the chemical structures of gas hydrates formed in aqueous solutions.
