Talk Title: Additive manufacturing of ceramics based materials

Abstract: The ceramics based materials fabricated using additive manufacturing technologies at the University of Queensland will be introduced. Laser engineering net shaping technologies are developed to fabricate advanced bulk ceramics. The ceramics being fabricated exhibit a refined eutectic structure, a near full density, and excellent mechanical properties and fracture toughness. The mechanism of interaction between laser melting and the resultant mechanical properties and surface integrity of the fabricated components are discussed. Using laser cladding ceramics composite coatings are successfully fabricated on Ti alloy substrates. The unique ceramic coatings have a much higher hardness than the base alloy, and the wear resistance of the coating/substrate system is substantially improved. The strong adhesion between coating and substrate is attributed to the improved performance of the coating/substrate system.

Talk Title: Integrating Artificial Intelligence in 3D Printing towards Digital Manufacturing 4.0

Abstract: Over the last decade, Industry 4.0 has focused more on digitalization and AI-driven technologies  for  improving  the  efficiency  and  flexibility  of  production.  Existing structures and processes in the manufacturing industry are reaching their limits in terms  of  flexibility,  the  feasibility  of  complex  parts,  and  product  customization. However,  3D  printing  offers  a  comprehensive,  intelligent,  and  digitally  optimized solution to these challenges. Due to the ability to fabricate parts with complex features, Additive Manufacturing (AM), also known as 3D printing, is rapidly gaining traction in the manufacturing industry. The researchers have focused on the reliability of 3D printed parts in order to realize AM as an end-part production tool. Thus, Industry 4.0 pillar technologies such as Machine learning (ML) has been used in various aspects of AM  to  improve  the  overall  design,  the  manufacturability  of design  as  well  as  for improving manufacturing process parameters, particularly in the industrial era. 4.0. Therefore, in this keynote talk various types of ML techniques are first introduced. Then, the discussion progresses on their implementation in various aspects of AM, including   3D  printing   design,   material   tuning,   process   optimization,  in   situ monitoring, cloud service, and cyber-security.

Talk Title: 2D Materials for Real-World Applications: Graphene Oxide Liquid Crystal & Single Atom Catalyst

Abstract: Following the early day scientific research efforts to understand the interesting structures and properties of 2D materials, such as graphene, their chemically modified forms are attracting a great deal of research attention nowadays, particuarly aiming at real-world applications. Among several different chemically modified derivaties of graphene, graphene oxide liquid crystal (GOLC) is a well-established 2D carbon based soft material system, which exhibits nematic type colloidal discotic liquid crystallinity with the orientational ordering of graphene oxide flakes in good solvents, including water. Since our first discovery of GOLC in the aqueous dispersion at 2009, this interesting mesophase has been utilized over world-wide for many different application fields, such as liquid crystalline graphene fiber spinning, highly ordered graphene membrane/films for water purification, 3D graphene assembled structures for energy & environmental applications, prototype liquid crystal display and so on. This presentation will introduce our current status of GOLC research, focusing on the nanoscale assembly of functional nanostructures. Besides, relevant research works associated to the nanoscale assembly and chemical modification of various low dimensional materials, including 2D TMDs and MXene, will also be introduced. In the last part of presentaation, our first discovery of single atom catalyst (SAC) will be highlighted. Metallic or non-metallic single atom level heteroelement dopants can be stabilized in the 2D plane & edge of graphene based structdures, such as N-doped carbon nantobues and nanoribbons, and offers interesting catalyst behaviors. The ultimate atomic level utilization of catalytic sites as well as peculiar novel catalytic performance of SAC opens up unprecedented opportunity for energy & environmental applications. 

Biography: Prof. Kim attained his Ph.D. in 2000 from the Department of Chemical Engineering at KAIST and joined the Department of Materials Science & Engineering of KAIST as a professor in 2004. His main research interest is the directed self-assembly of soft materials, including block copolymers and 2D nanomaterials such as graphene oxide aiming at the practical utilization of the resultant nanostructures for electronics, energy, environmental and biological applications. Noticeably, he has pioneered the extension of molecular level self-assembly principle, previously mostly associated to biomolecules or polymers, for the general material fabrication methodologies based on various nanomaterials with molecular level precision. One of the prof. Kim’s well-known research achievements is the world-first discovery of graphene oxide liquid crystal. Since this original contribution, graphene based material fabrication has been rapidly advanced and approaching real-world applications in the form of 1D fibres, 2D films, and 3D nanoassmbled structures. Significantly, graphene oxide liquid crystal offers a valuable precursor state for the mass-production of sub-5 layer level high quality graphene powders. His contribution in materials research has been widely appreciated by prestigious honours, including the youngest fellow of the Korea Academy of Science and Technology (2020), Highly Cited Researcher from Clarivate Analytics (2018), the KAIST Grand Prize for Academic Excellence (2015) and Presidential Young Scientist Award (2013).
