Synthesis of metal carbonyl agents as crosslinkers for granite sealers**

花岗岩由于其独一无二的图案和纹理，是一种用于个性化家居装饰的有利材料。然而，花岗岩由于其多孔结构，容易被染色。这是Allymarble Granite Ltd.(AGL)的一项主要工作，目的是封堵毛孔。交联剂是密封剂的基本成分。为了升级密封剂，该公司正在寻找无毒和非挥发性的交联剂，以降低废物处理的成本，并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，不挥发。另一方面，金属羰基是可降解的，它使产生不溶性物质的有机链段发生交联。因此，这些材料作为新一代密封剂的交联剂是值得探索的。通过与AGL合作，将设计和合成两个化合物用于探索。第一种是含有两个金属羰基端基的水溶性有机聚合物。聚合物部分将改善该试剂与密封剂的其他成分的相容性。第二种是一种化合物，它可以在水中组装，形成纳米颗粒，所有金属羰基都暴露在水中。较大的纳米颗粒比表面积将大大提高交联反应的效率。AGL将与王博士合作，用密封剂配制设计的材料，并测试它们的密封性能。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。这项研究旨在为加拿大工业带来颠覆性创新，将创造新的商业机会和高薪技术工作岗位。合作还将创建一个培训高素质人才(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。*

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.****
