This proposal concerns the acquisition of an inert atmosphere workstation, or glove box. A glove box workstation allows for the preparation, storage and analysis of very reactive chemicals under safe conditions. For example, some of the chemicals made by the group, or their starting materials, will spontaneously catch fire upon exposure to air outside of the inert nitrogen atmosphere within the glove box.  The compounds made by students and researchers in my group will be used as initiators or catalysts for making new polymeric materials (plastics) from renewable starting materials (feedstocks). Most modern plastics are made from petrochemical sources, which are quickly becoming depleted or prohibitively expensive. Our research seeks ways to improve our use of these resources in a more energy efficient and higher yielding manner. We are also using alternative starting materials that can be obtained cheaply from renewable sources, such as plants, or from waste products, such as carbon dioxide (CO2). In short, can we make new plastics from chemicals obtained from plants, as well as use at least some of the CO2 that is accumulating in our atmosphere?  The problem with many of these starting materials, especially CO2, is that they are very unreactive and require forcing conditions (such as long reaction times, very high temperatures or pressures) in order for us to do chemistry with them. The use of metal-containing catalysts is one way to make the processes using these feedstocks more rapid and energy efficient. Since these catalysts must be very reactive, they must be handled under special conditions free from oxygen and water, which could destroy the catalyst.  A glove box is an essential piece of equipment in catalyst development laboratories worldwide. In discovering new catalysts, chemists can meet society's continuing desire for a high quality of life whilst enabling a sustainable future via new lower energy processes and alternative feedstocks. This research is also of importance in exploiting Canada's finite petrochemical resources in energy efficient and controlled ways.

这项提议涉及购买惰性大气工作站或手套箱。手套箱工作台允许在安全条件下制备、储存和分析活性极强的化学品。例如，该小组制造的一些化学品，或其起始材料，在接触到手套箱内惰性氮气气氛外的空气时会自发起火。此外，我所在小组的学生和研究人员制造的化合物将被用作引发剂或催化剂，用于从可再生的起始材料(原料)制造新的聚合物材料(塑料)。大多数现代塑料都是由石油化工原料制成的，这些原料正在迅速耗尽或昂贵得令人望而却步。我们的研究寻求以更节能和更高产量的方式改善我们对这些资源的使用。我们还在使用可从植物等可再生资源或二氧化碳(CO2)等废物中廉价获得的替代起始材料。简而言之，我们能否利用从植物中获得的化学物质来制造新塑料，并至少使用我们大气中积累的部分二氧化碳？许多这些起始材料，特别是二氧化碳的问题是，它们非常不起反应，需要强制条件(如较长的反应时间、非常高的温度或压力)才能与它们进行化学作用。使用含金属催化剂是使使用这些原料的过程更快速和更节能的一种方式。由于这些催化剂必须非常活性，它们必须在没有氧气和水的特殊条件下处理，这可能会破坏催化剂。手套箱是世界各地催化剂开发实验室的必备设备。通过发现新的催化剂，化学家可以满足社会对高质量生活的持续渴望，同时通过新的低能耗工艺和替代原料实现可持续的未来。这项研究对于以节能和可控的方式开发加拿大有限的石化资源也具有重要意义。
