Water is one of the most significant compounds in nature that is not only responsible for life but also plays a significant role in many processes related to energy and safety. Water can undergo two significant phase changes when it is exposed to the proper thermodynamic conditions and components: Ice and Gas Hydrate. Ice accretion on modern infrastructure such as aircrafts, ships, offshore oil platforms, wind turbines, telecommunications and power transmission lines jeopardizes their integrity and poses a significant safety hazard to operators and civilians alike. Gas hydrates on the other hand, are viewed as a new/alternative method to sustain our increasing energy demands and hence, our quality of life. Naturally occurring gas hydrates have enormous amounts of stored energy that exceeds conventional carbon reserves and mostly contain natural gas. The add-ons requested in this proposal to the existing High-Pressure Rheometer will provide a unique insight into the flow of water, in a liquid state, but also as a slurry with soft-solids (ice and hydrate). The range of temperatures and pressures with the custom unit described can be performed with only one other unit (in Austria, that we are aware of). This information is essential for the design of safe, economical, and environmentally responsible processes and facilities to deal with ice and hydrate-forming systems, as well as for the exploitation of in-situ methane hydrate as a future energy resource. Further enhancements to the rheometer include studying phase change materials using a UV curing system (to pattern surfaces) and an extensional rheometer tooling to again orient surfaces via extensional flow to observe the effect of patterned surfaces on ice accretion and related phenomena. A novel approach will be undertaken in this work, exploring the effects of nanomaterial surfaces and polymeric additives on both ice and gas hydrate forming systems. The goal is to elucidate the behavior of the flow of water in the presence of these surfaces and additives as it transitions to either ice or hydrate. The outcome of such work has the potential to place Canada at the forefront of technologies related to de-icing techniques that preclude ice accretion and natural gas recovery, storage and transportation.

水是自然界中最重要的化合物之一，不仅对生命负责，而且在与能量和安全有关的许多过程中起着重要作用。当水暴露于适当的热力学条件和成分时，水可以发生两个重大的相变：冰和气体水合物。现代基础设施（例如飞机，船舶，海上石油平台，风力涡轮机，电信和电力传输线）上的冰收集危害了它们的诚信，并对运营商和平民构成了重大的安全危害。另一方面，气体水合被视为一种新的/替代方法，可维持我们不断增长的能源需求，从而维持我们的生活质量。天然存在的气体水合物具有大量的存储能量，超过了常规的碳储量，并且主要含有天然气。该提案中要求的附加组件对现有的高压性休斯仪将提供对液态水流的独特见解，但也可以作为具有软固醇（冰和水合物）的浆液。所述的自定义单元的温度和压力范围只能与另一个单位（在奥地利，我们知道）进行。此信息对于设计安全，经济和对环境负责的过程和设施的设计至关重要，以处理冰和水合体形成系统，以及将原位甲烷水合物作为未来能源的开发。对流变仪的进一步增强包括使用紫外线固化系统（至模式表面）研究相变材料，以及通过伸展流动的伸展表面进行延伸的浮标工具，以观察图案表面对冰积聚和相关现象的影响。这项工作将采用一种新颖的方法，探讨纳米材料表面和聚合物添加剂对冰和气体水合物形成系统的影响。目的是在存在这些表面和添加剂的情况下阐明水流的行为，因为它过渡到冰或水合物。此类工作的结果有可能使加拿大成为与排放技术相关的技术的最前沿，这些技术排除了冰期冰的冰期和天然气回收，储存和运输。
