The IAS and the Graduate Student’s Club of CCEB, SPMS, and MSE jointly organised the colloquium titled "New Catalysts, New Reactions and New Functional Materials", featuring Prof Hou Zhaomin. He is the Group Director of Advanced Catalysis Research at RIKEN Center for Sustainable Resource Science, and the Director of the Organometallic Chemistry Laboratory at RIKEN Cluster for Pioneering Research.
During the colloquium, Prof Hou Zhaomin delved into the noteworthy milestones attained in organometallic chemistry. He shared profound insights into a novel cohort of organometallic catalysts meticulously crafted by him, ushering in a realm where distinctive and efficient chemical transformations occur, paving the way for the creation of avant-garde polymers.
In addition, Prof Hou addressed the overarching issue of ligand redistribution, offering valuable insights into his proposed approach to tackle this challenge. This discussion underscored the crucial importance of advancing catalyst development in the realms of both chemical synthesis and materials progression.
The strides made in organometallic chemistry, with a specific focus on the rare and stable Lanthanides, stand out as noteworthy accomplishments. Prof Hou elucidated the noteworthy developments, particularly in the context of the remarkable formation of Ln-C and Ln-H bonds. Moreover, he shed light on a groundbreaking achievement - the inception of the first syndiospecific living polymerisation of styrene. This transformative process utilised cationic half sandwich rare earth alkyls, further enhancing the repertoire of possibilities in polymerization techniques.
In addition to his prior achievements, Prof Hou Zhaomin has innovatively pioneered a technique for copolymerising styrene with ethylene utilising a Ti-catalyst. Furthermore, he successfully executed oxygen-assisted alpha olefin polymerisation employing the Sc catalyst.
Notably, the colloquium featured his groundbreaking work in the development of a self-healing polymer, exemplified through the demonstration of a cut-and-heal polymer. He shared several videos illustrating the polymer's remarkable ability to reattach itself even after undergoing cutting or breaking.

Following the presentation, the audience actively engaged in the Q&A and posed questions such as the healing time and duration required for the polymer to recover after being severed. Prof Hou adeptly addressed these queries, providing insightful responses. His useful suggestions and advice garnered applause from the audience.
