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，因为其一种独一无二的图案和纹理。但是，由于其多孔结构，花岗岩很容易被染色。这是Allymarble Granite Ltd.（AGL）密封孔的主要工作。交联剂是密封剂的必要成分。为了升级密封剂，该公司正在寻求无毒和无挥发性的交联，以降低废物处理的成本并确保安全的工作环境。 Wang博士在滑铁卢大学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，这些化合物对细胞和非挥发性无毒。另一方面，金属羰基是可降解的，它可以交叉链接产生不溶性材料的有机细分。因此，值得探索这些材料作为密封剂的新一代交联。通过与AGL合作，将设计和合成两种化合物，以供探索。第一个是水溶性有机聚合物，有两个金属羰基基团。聚合物段将改善代理与密封剂其他成分的兼容性。第二种是可以在水中组装的化合物，形成纳米颗粒，所有金属 - 键盘基团暴露于水中。纳米颗粒的较大表面积将大大提高交联反应的效率。 AGL将与Wang博士一起使用密封剂制定设计的材料并测试其密封行为。这项合作是AGL开发高价值添加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行业做出破坏性创新，将创造新的商机和高薪的技术工作。联合工作还将创建一个培训高质量人员（HQP）的平台，他们将能够使用新兴知识为行业创新做出重大贡献。********
