"First Principles Alloy Theory – A Retrospective"
Since Hume-Rothery, Pauling, and Friedel, Alloy Theory has been influenced by electronic structure theory. Whereas Density Functional theory has had, for a long time, a significant impact on our understanding of ordered solids, only in the past two decades has it been combined with statistical mechanics to produce a viable, electronic-structure-based theory of alloys. Zunger will describe his personal view of this development, including the development by his colleagues and collaborators of foundational tools of the trade (total-energy concept and first-principles pseudopotentials), through "first-principles thermodynamics" and computational discovery of new materials, in the areas of metal alloys, semiconductor alloys, and insulator alloys.

"Towards Sustainable Metal Production by Molten Oxide Electrolysis"
It has been known that metals having ultra-fine grains (UFGs) produced by severe-plastic deformation processes exhibit unique mechanical properties such as hardening by annealing and softening by deformation in UFG-Al [1]. Although the unique phenomena are associated with the high dislocation density LV (m-2) and high density of grain boundary SV (m-1), there are few quantitative reports about those lattice defects. In the present study, an accumulative roll bonding (ARB) process was used to fabricate the UFG metals. The change in LV, depending on the number of the ARB cycle, was quantified using transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM) and electrical resistivity measurements at 77 K. As a result, it was revealed that LV is almost constant for all ARB processed metals, with values of around 1.0×1014m-2 and 5.0×1014m-2 for UFG-Al and UFG-Cu, respectively.

"Not a Molecule, Not a Polymer, Not a Substrate . . . the Many Faces of Graphene as Chemical Platform"
What is, exactly, graphene?

While we often describe graphene with many superlative adjectives, it is difficult to force this (superlative) material within a single chemical class. Graphene typical size is atomistic in one dimension of space, and mesoscopic in the others two. This provides graphene with several, somehow contrasting properties. Graphene can be can be patterned, etched and coated as a substrate. Though, it can also be processed in solution and chemically functionalized, as a molecule. It could be considered a polymer, obtained by bottom-up assembly of carbon atoms, but it can be obtained from top-down exfoliation of graphite (a mineral) as well. It is not a nano-object, as fullerenes or nanotubes, because it does not have a well-defined shape; conversely, it is a large, highly anisotropic, very flexible object, which can have different shapes and be folded, rolled or bent to high extents.

In this presentation, we will discuss the state of the art and possible applications of graphene in its broader sense with a particular focus on how its "chemical" properties, rather than its well-known electrical ones, can be exploited to develop original science, innovative materials and new technological applications.

"Tunable Nanostructures and Printed Electronics"
The properties of materials are typically controlled by their microstructure. As a consequence, the properties cannot be altered reversibly. In contrast, gating using electrical charges allows for the reversible change of properties and has an enormous potential for applications. In general, charges can be applied at interfaces between an oxide (dielectric gating) or an electrolyte (electrochemical gating) and the material. This can be applied for the reversible change of mechanical, electrical and magnetic properties of nanostructures. In a similar way, electrochemical gating can be applied to printed field-effect transistors based on inorganic oxide nanoparticles. The basic principles of tunable nanostructures will be discussed, as well as the application of the electrochemical gating concept for printed electronics. The technical performance, such as field effect mobility, device speed, temperature range, etc. will be highlighted.

"Sustainability: A Paradigm Shift for Metals?"
The global demand for technology metals has drastically increased. This will further accelerate as a result of the introduction of green and high-tech technologies. To secure a reliable and sustainable supply of these metals, innovative solutions need to be developed along the entire value chain. This requires a system-wide approach focusing on sustainable mining methods, substitution of critical metals, and recovery of metals from secondary sources. Even more than today, the walls between different research areas, metal and product sectors, industries, corporations and SMEs, industry and policy makers, countries etc. need to be removed.

Sustainable solutions hinge on the development of technologies that simultaneously seek gains in economic, social, and environmental aspects. When applying this to metal recovery from complex sources, coupling between metals imposes certain trade-offs. This balancing issue is explained by means of the periodic table of elements. Strategies to overcome related metallurgical challenges are illustrated in Umicore’s flowsheet. The latter is designed to recover metals in low concentrations from intermediates and end-of-life products with a high recovery yield and minimal emissions and waste.

Another key element facilitating the transition toward sustainability is cross-border and cross-sectoral collaboration. The need to enhance connectivity is recognized on the global as well as regional level. The EU-Japan-US trilateral roundtable on critical raw materials brings together different stakeholders from across the world. In Europe, the "Innovation Union" flagship initiative within the Horizon 2020 strategy aims to foster innovation by adopting a joint stakeholders approach. In the U.S., the aspect of interconnection is implemented through the formation of Energy Innovation Hubs, among others. Active engagement of the metals and materials industry in these initiatives is key to driving the paradigm shift needed to achieve a sustainable society.

"A Scientist, a Parent, a Teacher, a Mentor… How to Balance it All?"
In my Young Leaders Tutorial Luncheon Lecture, I would like to focus on the issues of work/life balance as a woman in academia and on how to balance the professional and personal activities without feeling overwhelmed.

"Would you be willing to participate in a panel discussion on work/life balance at Meeting/Conference/Workshop X please?" is the question I hear quite often – maybe because I am a faculty advisor to Women Mentoring Women and Society of Women Engineers at Caltech, or maybe because there aren’t enough women in scientific/engineering academia, or maybe because people see me roller blading on campus with two kids in the stroller on the way to work. Whatever the reason, I have been thinking about these issues for quite some time now – whether it is possible to strike a meaningful and satisfying balance between one’s professional and personal "selves." In all honesty, there are days (nights) where I feel like I don’t ever stop working. Now that I am a Mom of two little girls (one is four and another one is almost two), trying to set up a work-life balance has been more challenging than I had ever imagined. Yet it is of key importance as I find that spending quality time with my children makes me a better scientist and intense scientific pursuit facilitates better parenting. In this lecture, I will focus on discussing the issues associated with trying to survive in the world where career, family, and hobbies simultaneously require 100% of one’s attention. I will provide examples of effective and ineffective situations, statistical data, and bring to light some of the perhaps surprising consequences of neglecting to find one’s internal balance.

"Lithium: Solving Global Energy Issues"
Lithium, the lightest metal in existence, has taken on a new importance in global energy markets. As nations search for ways to become more energy efficient and self-reliant, the production and use of electricity is now a greater focus. Lithium ion batteries provide a cost effective and reliable storage method for electrical energy today. While the battery industry and research institutions remain highly fragmented in approach, they all race to improve the same battery performance metrics. Solving some of these metrics could lead to the next global growth market. However, lithium’s contribution toward solving energy needs do not begin and end with batteries. The growing use of aluminum lithium alloys in aerospace for weight reduction and the addition of lithium salts to save energy when operating melt furnaces are among other energy saving applications for lithium. While elemental lithium is found everywhere, factors like economics and geopolitical dynamics limit the focus of major lithium producers to source raw material from only a few places around the world. However, unlike other key global resources, lithium can be part of the energy solution for a much longer duration because it lends itself to recycling. This presenter will discuss the lithium industry, key growth markets, technology trends and other outside influences on the broader use of lithium when solving global energy issues.

"It Is Rocket Science: The Engineering and Impact of Carbothermal Magnesium Technology"
Carbon is regularly used as a reductant for the production of many metals due to its simplicity, efficiency, and ease of use. For light metals the thermodynamics – and engineering – are more complex. The production of magnesium by carbothermal reduction has been a goal for nearly a century, yet significant practical challenges have made its operation uneconomic. A multi-disciplinary team from Australia’s national research organisation, CSIRO, has proven the technology at laboratory scale and demonstrated the operation of supersonic ‘shock quenching.’ This technology, called MagSonic™, is likely to be cost-competitive with existing processes while reducing energy consumption by up to 50% and environmental impact by up to 85%. Further advantages can be gained from renewable energy and carbon sources. This presentation will discuss the engineering challenges overcome in the development of MagSonic™ technology so far, and its potential to change the production and use of magnesium around the world.

Antibacterial Nanosized Silver Substituted Hydroxyapatite with Enhanced Mechanical Properties
Among the bioactive materials that have been used for orthopedic biomaterials design, hydroxyapatite [Ca10(PO4)6(OH)2] is a good candidate owing to its biocompatibility, osteoconductive properties and its presence in natural hard tissue. Poor mechanical properties such as brittleness, low tensile strength and poor machinability restrict their application. In this work we fabricated silver substituted hydroxyapatite [Ca10-xAgx(PO4)6(OH)2] with enhanced mechanical and antibacterial properties.
