Lugar: Seminario I, 4a planta Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos
Horario: 12:00 h.
Descripción: Conferencia impartida por el Prof. Dr. Kay Raum Julius Wolff Institut & Berlin-Brandenburg School for Regenerative Therapies, Charité – Universitätsmedizin Berlin, dentro de las actividades del Seminario José Antonio García García.
Este Seminario es un punto de encuentro para divulgar la actualidad en investigación, tanto en nuestro medio como en otros centros de referencia, destinado tanto a académicos como a alumnos. Para estimular la participación de los alumnos de grado de la ETSICCP, se concederá 1 crédito de Libre Configuración por la asistencia y presentación de un comentario personal a 5 seminarios durante el curso académico. Para los alumnos del Máster en Estructuras, este seminario se enmarca dentro de la asignatura de Seminarios de Ingeniería de Estructuras.
Resumen: Sophisticated technical materials that are used in everyday life are often inspired by nature. Lightweight honeycomb constructions and carbon fiber re- inforced sandwich composites, for example, are used to construct airplanes, cars or modern sports equipment and aim to optimize various properties, e.g. weight, toughness and strength that cannot be achieved by a single material. Hard biological tissues, e.g. mineralized tendons, bone and teeth are natural examples of achieving unique combinations and also great variability of stiff- ness and strength. In order to achieve these goals, bone uses various design concepts, e.g. reinforcing a soft and flexible collagen matrix by stiff, but brit- tle mineral particles, sandwich compounding of anisotropic (directional) films, weight reduction by directional pores and spongy networks. Although many details of the genetics, biology, pathology and mechanics of bone have been uncovered, we still lack of a detailed understanding of bone structure at the nano- and microscales. Towards this goal, both experimental data of hetero- geneous elastic and structural parameters from all length scales (from the centimeter to the nanometer scale) and theoretical models that can simulate the deformation behavior based on these data are required.
In this presentation the concept of multi-modal coupled multi-scale assess- ment of tissue properties (using quantitative ultrasound, synchrotron radiation μCT and vibrational microscopy) and modeling (using various homogeniza- tion techniques) will be presented with an emphasis of applications in mus- culoskeletal research, e.g. bone and cartilage healing.
