My research is primarily concerned with developing Solid-State Nuclear Magnetic Resonance (SSNMR) methods to study the structure and molecular motion of Complex Hybrid Organic-Inorganic Materials (CHOIM) using fluorine and phosphorous as probes. Synthetic CHOIMs are found in alternative energy (fuels cells, solar cells) and battery technologies, whereas natural CHOIMs exist as complex mixtures such as bitumen and biomaterials. CHOIMs are typically composed of various combinations of soft, hard and fluid components, which have to be studied as they are, not in isolation, in order to appreciate the interactions between components that give rise to the properties and behaviours of interest. As such, they are ideally characterized by SSNMR spectroscopy. The repertoire of structural and dynamic SSNMR methods, as well as simulations tools, will be continually expanded to meet new challenges posed by the complexity of emerging material technologies. The facility in Lethbridge is one of the best equipped in Canada for SSNMR of materials, resulting from a series of strategic investments by the UofL in its materials chemistry research capability, by building state-of-the-art synthetic and characterization facilities, thereby forming the core of a centre of expertise in fluorine chemistry and materials characterization. Materials of interest include: nanocomposites of inorganic polymers, fluoropolymers, and block copolymers. These new SSNMR methods will also be used to chemically fingerprint bitumen, which has confounded traditional characterization methods, to provide much needed structural and compositional information to advance upgrading and extraction processes for the oil sands industry. This process involves the introduction of 19F as a probe by low level direct fluorination. My research group represents the only Canadian research presence focused on SSNMR of hybrid organic-inorganic materials. A Canadian presence facilitates the participation of our materials science community in the development of new organic-inorganic hybrid technologies, thus benefiting from its ever widening range of applications and subsequent economic impact in the areas of alternative energy, electronics, environment, fossil fuels, medicine and agriculture.

我的研究主要涉及开发固态核磁共振（SSNMR）方法，以使用氟和磷作为探针来研究复杂杂化有机-无机材料（CHOIM）的结构和分子运动。合成 CHOIM 用于替代能源（燃料电池、太阳能电池）和电池技术，而天然 CHOIM 以复杂混合物形式存在，例如沥青和生物材料。 CHOIM 通常由软、硬和流体成分的各种组合组成，必须按原样而不是孤立地研究这些成分，以便了解产生感兴趣的特性和行为的成分之间的相互作用。因此，它们可以通过 SSNMR 光谱进行理想的表征。结构和动态 SSNMR 方法以及模拟工具将不断扩展，以应对新兴材料技术的复杂性带来的新挑战。莱斯布里奇的设施是加拿大材料 SSNMR 设备最齐全的设施之一，源自伦敦大学对其材料化学研究能力的一系列战略投资，通过建设最先进的合成和表征设施，从而形成氟化学和材料表征专业中心的核心。感兴趣的材料包括：无机聚合物、含氟聚合物和嵌段共聚物的纳米复合材料。这些新的 SSNMR 方法还将用于对沥青进行化学指纹识别（这与传统的表征方法相混淆），以提供急需的结构和成分信息，以推进油砂行业的升级和提取过程。该过程涉及通过低水平直接氟化引入 19F 作为探针。我的研究小组是加拿大唯一专注于有机-无机杂化材料的 SSNMR 的研究机构。加拿大的存在促进了我们的材料科学界参与新型有机-无机混合技术的开发，从而受益于其在替代能源、电子、环境、化石燃料、医药领域不断扩大的应用范围和随后的经济影响和农业。
