Immobilization of active molecules in nanostructured materials for multifunctional coatings
Additives to coatings can confer them important functionalities. However, direct mixing of them with coating formulations can lead to important drawbacks decreasing other important properties of the coatings, making them inappropriate for certain applications. This could be the case with certain active molecules, which are able to inhibit corrosion, have anti-fouling properties, sense different stimuli and increase adhesion. Preferably the added molecules should be released along time and thus become active upon external triggers (pH, chlorides, temperature, UV, stress, etc.). In order to achieve the controlled release and avoid interference with the coatings the active molecules must be encapsulated in nano/micro-containers. Other properties as rheology and curing of the coatings need to be optimized in order to have an effective effect. Ecotoxicity is another aspect to be taken into account. The development of new nanocontainers for organic and inorganic corrosion inhibitors achieved is described, especially the most promising from industrial point of view, based on Layered Double Hydroxides (LDH). They were mainly used for AA 2024 alloy. Emphasis will be given to MBT as an ionic exchanger with both inhibitor and anti-fouling properties. The combination of different of these nanocontainers in the same coating system has proved to be effective to accomplish further functions as antifouling and sensing.

KTH Royal Institute of Technology, Sweden
During 30 years that have passed since his appointment as Professor of Corrosion Science at KTH Royal Institute of Technology in Stockholm, Sweden, Christofer Leygraf has founded and maintained a large research group that deals with a broad range of basic and applied aspects of atmospheric and aqueous corrosion. Sustainable activities have been developed to establish a more fundamental foundation of atmospheric corrosion, largely through cross-disciplinary interaction between scientists in physics, chemistry, materials science and environmental science. These efforts were recently summarized in the second edition of the book Atmospheric Corrosion (Wiley, 2016). Christofer Leygraf is an elected member of the Swedish Royal Academy of Sciences and Honorary professor at the University of Science and Technology, Beijing (China). He has received a number of international awards and distinctions, including the 2003 Herbert Uhlig Award (US), 2006 Khwarizmi International Award (Iran), 2007 Willis Rodney Whitney Award (US), 2009 U.R. Evans Award (UK) and the 2013 European Corrosion Medal (EFC).
Atmospheric Corrosion: Current Challenges in an Evolving Research Field
Atmospheric corrosion is probably the most complex form of corrosion. The reason is that three phases (atmosphere, aqueous, solid) and two interfaces (atmosphere/aqueous and aqueous/solid) act simultaneously. To extract more basic information on the physicochemical processes that govern atmospheric corrosion it is necessary to design and study model systems, which are simple enough for fundamental studies, yet complex enough to be relevant for practical purposes and applications. Due to international exposure programs, sophisticated laboratory experiments, developments of more advanced analytical techniques and advancements in computational modelling, our understanding of atmospheric corrosion has greatly increased. This Award address will highlight a few challenges from current studies in the author’s ongoing research activities in atmospheric corrosion, with a focus on copper. They include the design of model systems, corrosion monitoring under in situ conditions with extremely mass sensitive techniques, and computational first-principle efforts for extracting molecular information on vital aspects of atmospheric corrosion.

In his career he has made major contributions to understanding building microclimate and its effect on durability, fundamental nature of atmospheric corrosion and the role of droplets in controlling it, multi-scale modelling and virtual design, new coating development, sensors and vehicle health monitoring, nano sensors and autonomous discovery of materials.
Virtual Design, Robotic Discovery and High through Put Studies of Atmospheric and Aerospace Corrosion
We can now fabricate and control structures at the molecular level. This is dramatically increasing the range of functionalities and the effectiveness of those functions within our materials. However it also leads to massive increase in the number of design choices and thus demands new rapid methods to select the best molecular designs. This paper will outline new methods to both assess the likely performance of corrosion resistant materials and to rapidly select the optimum chemical and physical structures to assist in corrosion control. The emphasis will be on new corrosion inhibitors. Techniques that will be explored will include virtual design where a multi-scale model spanning scales from nano meters to continents is presented. This model allows the estimation of the life of an inhibited paint film as a function of both the molecular properties of the inhibiting molecule and the service profile of the aircraft. The use of high throughput and robotic electrochemical studies were up to 80 experiments are carried out simultaneously both to explore independently design alternatives and to feed into the virtual design system will be explored

Needs, Gaps, and Opportunities for Better Design of Corrosion Resistant Materials
Alloys are often designed with properties other than corrosion resistance as a high priority, such as mechanical strength. In the past, alloys were seldom designed with an exclusive focus on optimization of corrosion resistance. When corrosion was a priority, trade-offs between optimization of one property and another often existed. Such beneficial elements are often discovered by trial and error and utilized successfully despite unknown or widely debated mechanisms often discovered by accident. A recent National Academy study pointed out that an ideal corrosion-resistant alloy formulated with corrosion in mind from the initial stages of integrated computational materials design could also take advantage of many other beneficial attributes. Theory guided computational materials selection will be required. A primary challenge exists to connect the attributes defined feature space of an alloy with the subsequent properties. This connection requires that scientific principles are established between each feature or attributes and the subsequent property. However significant scientific needs, gaps, and opportunities must be addressed to improve the theory based design of emerging materials for improved corrosion resistance.
