Materials Science and Engineering – MSE 2012 Conference
Darmstadt, Germany, September 25–27, 2012


The Materials Science and Engineering – MSE 2012 Conference was held in Darmstadt, Germany, on September 25–27, 2012. This international conference is organized by the German Materials Research Society (Deutsche Gesellschaft für Materialkunde – DGM) and is held every two years. The 2012 conference was hosted by the Technical University of Darmstadt. It was inaugurated by Prof. Jürgen Rödel of the University of Darmstadt and Prof. Matthias Kleiner, president of the German Research Foundation (Deutsche Forschungsgemeinschaft – DFG). In his inauguration speech, Prof. Kleiner drew attention to energy materials as a research field that would attract the greatest investment inflow in near future. The Materials Australia, which strives to intensify its collaboration with various organizations in Europe, was presented as the guest of this year's conference.

The conference featured more than a thousand presentations from 48 countries, divided into six topics:

A – Functional Materials
B – Structural Materials
C – Processing
D – Characterisation
E – Modelling and
F – Biomaterials

Special symposia were dedicated to materials engineering in Australia and Prof. Günter Gottstein, in whose honour leading researchers contributed to Symposium on microstructural designing and characterization of advanced materials.

The sessions were divided into 35 symposia, which featured 70 keynote and highlight lectures, 600 oral and about 450 poster presentations arranged in ten parallel sessions.

The conference featured seven plenary lectures which covered the most important research fields in materials science. Julian Allwood of Cambridge University, Great Britain, gave a lecture on sustainable materials, problems related to gas emission in the production of five major groups of materials (steel, cement, plastic, paper and aluminium), greater recycling efficiency aimed at a significant reduction of the need for new raw materials. Claudia Ambrosch-Draxl of the Humboldt University in Berlin, Germany, gave a lecture on the possibilities for the development of new functional materials based on theoretical physics predictions and computational materials science, illustrating this by the example of photovoltaic and optoelectronic materials. Bruno Charles De Cooman of the Pohang Institute of Science and Technology (South Korea) spoke of the control of deformation hardening of ultra-fine grain steel for car industry. Kristi Kiick of the University of Delaware, active in biomaterials research, discussed the application potential of the combination of biosynthetic methods, bioconjugation strategies and a biomimetic approach in designing novel biomaterials for application in cardiovascular therapy and controlled drug delivery. Christopher Schuh of the Massachusetts Institute of Technology, USA, spoke about processing and deformation properties modelling of amorphous alloys, while Dwight Viehland of the Virginia Polytechnic Institute and State University spoke about the latest results in magneto-electric composites consisting of piezoelectric and magnetostrictive layers with strong magnetoelectric effect. Professor Viehland authored more than 390 papers, which have been cited more than 12,000 times. The research of Zhong Lin Wang of the School of Materials Science and Engineering Georgia Institute of Technology is focused on piezoelectric self-powered nanogenerators for micro/nanosystems. This is particularly relevant for wireless devices widely applied in modern industry and science.



Miodrag Lukiæ, a research assistant at the Institute of Technical Sciences of SASA, gave a poster presentation (Miodrag J. Lukiæ, Smilja Markoviæ, Dragan Uskokoviæ, Influence of grain size reduction from micro- to nano-level on electrical properties of fully dense hydroxyapatite bioceramics) within Session F1 – Biomaterials Applications. The significance of electrical properties of dense sintered hydroxyapatite for bone tissue reconstruction lies in its capacity for polarization, which ensures extra surface electrical charge. This has been demonstrated to play a major role in the adsorption of important biological macromolecules, a process which is necessary for successful implantation of artificial materials. This line of research witnesses an intensive development worldwide. The most important research groups in this field include: School of Mechanical and Materials Engineering, Washington State University, USA and Materials Research Centre, Department of Mechanical Engineering, University of Bath, UK.

Along with their relevance for biological materials, electrical properties of hydroxyapatite are important for its application as a sensor for CO and CO2, catalyst support, etc. Our results presented at the MSE 2012 Conference are very important because it is the first time that the electrical properties of hydroxyapatite have been brought into relationship with the controlled structure and phase composition. For the first time, separate contribution of grain-boundary resistivity and the resistivity of the material, and activation energy in a broad temperature interval, both in heating and cooling regimes, have been demonstrated. The study has shown that changes in the ionic conductivity mechanism occur in the heating regime, which is indicated by different activation energies in different temperature intervals, whereas during cooling, a single ionic conductivity mechanism prevails. Furthermore, despite the greater share of grain boundaries in the nanostructured sample, the sample with an average grain size of 75 nm exhibited greater conductivity than the samples with grains on submicron and micron scales.

As for the topicality and quality of the research programmes in biomaterials carried out at the Institute of Technical Sciences of SASA, the insight into the results presented at the MSE Conference has proved their great topicality. However, our research is prevailingly focused on fundamental problems, whereas in Germany, as a technological and scientific power, accent is laid on materials' application properties. Accordingly, the key point in discussions following numerous presentations was the issue of the quantification of discovered effects and comparison with the values measured in previous research.

Prof. Aldo Boccaccini of the Department of Materials Science, University of Erlangen-Nuremberg, Germany, who was the coordinator and chairman of Session F1 – Biomaterials Applications, spoke with praise of the YUCOMAT conference as an opportunity to bring together materials science re researchers on a regional level and enable them to search for new ideas and a new impetus in collaboration with world famous scientists.
