Granite is a favorable material used to personalize home decorations due to its one-of-a-kind patterns and textures. However, granite is easy to be stained due to its porous structures. It is a major work at Allymarble Granite Ltd. (AGL) to seal the pores. Crosslinking agents are essential ingredients for the sealers. To upgrade the sealers, the company is seeking crosslinkers that are non-toxic and non-volatile to reduce the cost on the waste-treatment and ensure a safe work environment. Dr Wang at the University at Waterloo is working on the synthesis and self-assembly of metal carbonyl organometallic compounds. He has reported that these compounds are non-toxic to cells and non-volatile. On the other hand, the metal carbonyl group is degradable, which crosslinks organic segments producing insoluble materials. The materials are, therefore, worthy being explored as a new generation of crosslinkers for sealers. Two compounds will be designed and synthesized for the exploration via working with AGL. The first one is a water-soluble organic polymer with two metal carbonyl end groups. The polymer segment will improve the compatibility of the agent with other ingredients of the sealers. The second is a compound that can assemble in water to form nanoparticles with all metal-carbonyl groups exposed to water. The larger surface area of the nanoparticle will substantially increase the efficiency of the crosslinking reactions. AGL will work together with Dr Wang to formulate the designed materials with the sealers and test their sealing behavior. This collaboration is an opportunity for AGL to develop high-value added products and provide high quality services for Canadian citizen. The research, aiming to make a disruptive innovation for Canadian industry, will create new business opportunities and high paying technology jobs. The joint work will also create a platform to train High quality personnel (HQP), who will be able to make significant contributions to industry innovation using the emerging knowledge.****

花岗岩是一种有利的材料，用于个性化家居装饰，由于其独一无二的图案和纹理。然而，花岗岩由于其多孔结构而容易被染色。这是一个主要的工作在Allymarble花岗岩有限公司（AGL）密封的孔隙。交联剂是密封剂的基本成分。为了升级密封剂，该公司正在寻求无毒和不挥发的交联剂，以降低废物处理成本，确保安全的工作环境。滑铁卢大学的王博士正在研究金属羰基有机金属化合物的合成和自组装。他报告说，这些化合物对细胞无毒且不挥发。另一方面，金属羰基是可降解的，其交联有机链段产生不溶性材料。因此，该材料是值得开发的新一代密封剂的交联剂。通过与AGL合作，将设计和合成两种化合物用于探索。第一种是具有两个金属羰基端基的水溶性有机聚合物。聚合物链段将改善试剂与密封剂的其它成分的相容性。第二种是可以在水中组装形成纳米颗粒的化合物，所有金属羰基基团都暴露在水中。纳米颗粒的较大表面积将显著增加交联反应的效率。AGL将与王博士一起制定设计的材料与密封剂和测试他们的密封行为。此次合作是AGL开发高附加值产品并为加拿大公民提供高质量服务的机会。该研究旨在为加拿大工业进行颠覆性创新，将创造新的商业机会和高薪技术工作。联合工作还将创建一个培养高素质人才（HQP）的平台，他们将能够利用新兴知识为行业创新做出重大贡献。
