The broader impact/commercial potential of this I-Corps project is the development of a method to remove oxygen from food storage and transport containers to decrease produce spoilage. Every year $160 billion worth of food is wasted in America at every stage of the supply chain. Improving food storage would improve this figure and enable environmentally sustainable transport options. The proposed technology may be implemented in several possible stages of the supply chain from farm storage, transportation (truck or ship), grocery store coolers, and for home use in personal refrigerators. This project will explore various paths for technology translation. This I-Corps project is based on the development of a reversible reaction of excited oxygen with a novel material. The material acts like an oxygen sponge, absorbing oxygen when irradiated with light, and releasing oxygen under warm, dark conditions. This allows the consumption of oxygen to be controlled using light, while the release can be manipulated with heat. The reaction occurs at low partial pressures of oxygen and can create oxygen-free environments. The oxygen may be stored in the material and released under gentle heating. This material and process may be used to remove or reduce oxygen from a space, creating an anerobic environment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目更广泛的影响/商业潜力是开发一种方法，从食品储存和运输容器中去除氧气，以减少产品腐败。美国每年在供应链的各个阶段浪费价值1600亿美元的食品。 改善粮食储存将改善这一数字，并实现环境可持续的运输选择。所提出的技术可以在供应链的几个可能的阶段中实施，从农场储存，运输（卡车或船舶），杂货店冷却器，以及家庭使用的个人冰箱。该项目将探索技术翻译的各种途径。这个I-Corps项目是基于开发一种新材料与激发态氧的可逆反应。这种材料就像一个氧气海绵，在光线照射下吸收氧气，在温暖、黑暗的条件下释放氧气。这允许使用光来控制氧气的消耗，而释放可以用热来操纵。该反应在低氧分压下发生，并且可以产生无氧环境。氧气可以储存在材料中并在温和加热下释放。该材料和工艺可用于去除或减少空间中的氧气，从而创造一个厌氧环境。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
