The broader impact/commercial potential of this I-Corps project spans the petrochemical, medical, and energy industries. The protective coatings developed in this project will allow for safer storage, transportation, and use of corrosive chemicals, as well as the containment and treatment of hazardous wastes. These coatings may also find application to medical instruments and devices, allowing longer lifetimes and lower risks of contamination. The same coatings will also be useful in improved electrochemical systems such as fuel cells and electrolyzers, which will allow for effective use of renewable energy. Because this technology allows the deposition of iridium oxide coatings that are only a few atoms thick, the virtues of iridium oxides can be imbued to surfaces using fractions of a percent of the iridium required by currently employed methods. This will improve the applicability of this rare, and otherwise cost-prohibitive element.This I-Corps project starts with a technology that allows the room-temperature deposition of iridium oxide coatings from a molecular organometallic precursor dissolved in water. The coatings are only a few atoms thick, but have been shown to be as impervious as iridium oxide coatings 500 times thicker, and more active than the thicker coatings as electrocatalysts for the oxidation of water and small organic molecules. Additionally, the coatings are electrically conductive. During this I-corps project, the team will gather information from potential customers to develop products that will best take advantage of this ultra-thin, protective and catalytically active coating. It is envisioned that this will be a transformative technology in some sectors, allowing devices and systems with unprecedented functionality and durability.

该 I-Corps 项目的更广泛影响/商业潜力涵盖石化、医疗和能源行业。该项目开发的防护涂层将使腐蚀性化学品的储存、运输和使用以及危险废物的遏制和处理更加安全。这些涂层还可以应用于医疗器械和设备，从而延长使用寿命并降低污染风险。相同的涂层还可用于改进的电化学系统，例如燃料电池和电解槽，这将允许有效利用可再生能源。由于该技术允许沉积只有几个原子厚的氧化铱涂层，因此可以使用当前采用的方法所需的铱的百分之几的几分之一来将氧化铱的优点渗透到表面。这将提高这种稀有且成本高昂的元素的适用性。I-Corps 项目始于一项技术，该技术允许从溶解在水中的分子有机金属前体在室温下沉积氧化铱涂层。该涂层只有几个原子厚，但已被证明与厚 500 倍的氧化铱涂层一样不渗透，并且作为氧化水和小有机分子的电催化剂比较厚的涂层更活跃。此外，涂层是导电的。在这个 I-corps 项目中，该团队将从潜在客户那里收集信息，以开发能够最好地利用这种超薄、保护性和催化活性涂层的产品。预计这将成为某些领域的一项变革性技术，使设备和系统具有前所未有的功能和耐用性。
