ACerS Edward Orton, Jr. Memorial Lecture: Ceramic Particles for Precision Drug Delivery: Sanjay Mathur1; 1University of Cologne
Chemical processing of functional ceramics has played a key role in converging disciplines, which is especially true for biomedical applications. For example, the development of biocompatible drug-carriers that can hold back the payloads and release the drugs or antibiotics at the specific diseased area is a materials processsing challenge. The selective transport and retention of drugs in sufficiently high concentrations at the target site is inhibited by various physiological barriers, which reduces or even blocks the therapeutic efficiency of molecular drugs. Therefore, advanced drug-delivery systems designed to overcome biological barriers are needed to meet the specific traits of physiological and disease-related barriers. In this context, chemically functionalized nanoparticles act as efficient drug-carriers to transport higher amounts of therapeutic payloads to diseased sites that also reduces the undesired off-site effects. Moreover, hollow nanocarriers can incorporate more than one drug enabling theranostic and theraregenerative approaches. Finally, ceramic nanoparticles can be modified with surface-bound target ligands to exploit the overexpression of receptors and promote cell specific attachment of the carriers for a localized high concentration of drug around disease sites. This talk will discuss the potential benefits of inorganic nanoparticles towards precision drug delivery.

AIST Adolf Martens Memorial Steel Lecture: Interface-based Design – A New Frontier for Microstructure Engineering of High-Performance Steels: Matthias Militzer1; 1University of British Columbia
The steel industry continues to develop new high-performance steels and innovative processing strategies to meet societal demands of sustainability in the energy, transportation and construction sectors. Computational tools have aided these developments since the introduction of thermo-mechanically controlled processed steels in the 1970s. In particular, the concept of microstructure engineering permits a knowledge-based approach by simulating the microstructure evolution to link the operational process parameters with the properties of the steel product. Recent advances in computational materials science have enabled modeling across different length and time scales where atomistic scale simulations are combined with meso-scale modeling on the microstructure length scale to establish predictive tools for the industrially relevant macro-scale. The present lecture will review these modeling strategies to provide a critical assessment of their achievements and limitations with an emphasis on phase transformations in advanced high-performance low carbon steels. In particular, an interface-based steel design approach will be discussed.

TMS/ASM Distinguished Lectureship in Materials and Society: Materials Research on Clean Energy: For the Sake of Our Grandchildren: Iver Anderson1; 1Ames Laboratory (USDOE), Iowa State University
To attack and, hopefully, to reverse greenhouse gas (GHG) growth, the critical but formidable goal of net zero GHG emissions by 2050 must be reached. This will require major efforts from across our society, especially a “leap of faith” by all the world’s economies. From the latest report by the Intergovernmental Panel on Climate Change (IPCC), it is becoming increasingly apparent that we must do this for the health and well-being of our own children and grandchildren, if we want to help them avoid predictable climate disasters. Therefore, we professionals in the materials science and engineering community must make our best efforts to work on important GHG emission challenges to make the economic leap to green technologies more pragmatic and palatable. Recent analysis shows that there are huge market opportunities that can arrive with clean energy transitions, particularly if several key materials technology barriers are overcome. With solutions to these critical materials problems resulting from research that is supported by enlightened governments and industry leaders, a new global energy economy can emerge quite naturally. This new sustainable economy has the potential to create millions of excellent jobs across a host of new supply chains, along with many more generations of smiling grandchildren!
