Speech title: Fascinating Potential of Cryogenic Treatment to Alter the Properties of a Magnesium Based Nanocomposite.
Speech abstract: New magnesium-based materials including nanocomposites have been evolving rapidly for over 20 years and have shown tremendous promise as potential material choice in both engineering and biomedical applications. The main driving force for such a development is the lightweight (typically 33% lighter than aluminum) of magnesium-based materials (~ = 1.74 g/cc) which can noticeably mitigate carbon footprint and greenhouse gas emissions. Currently, the choice of magnesium-based materials is rather limited and hence the efforts are continuing globally to develop magnesium-based materials which display a much wider range of properties akin to that of steels and aluminum-based materials. The variation in properties, irrespective of the type of metallic material, can be accomplished through judicious compositional modification, choice of primary and secondary processing and exposure to different temperatures (subzero and above zero degree centigrade) for a predetermined duration of time. The present talk accordingly will highlight the capability of sub-zero temperature treatment in altering various properties of a magnesium-based nanocomposite highlighting a new path in development methodology for magnesium-based materials..

Speech title: Piezo-actuated MEMS testing devices for materials characterization at the microscale.
Speech abstract: Microelectromechanical systems (MEMS) are small-scale devices that have already revolutionized a number of high-tech fields, owing to their versatile functionalities. However, there is still concern regarding their reliability, especially when they have to operate in harsh environments characterized by high temperature and humidity levels. The unknown behavior of the relevant structural parts under varying loading, as affected by possible microfabrication defects, can spoil the long-term performance of the devices. In this work, the reliability problem has been addressed by investigating the fatigue-induced delamination processes in polysilicon-based MEMS structures. Ad-hoc designed test structures featuring a piezoelectric actuation have been designed, aiming to maximize the stress state in regions susceptible to the said delamination events. An optimization strategy for the topology/shape of the test structures has been then proposed by taking advantage of a numerical investigation, to allow for all the possible dissipative phenomena that characterize the response of the movable structures at the microscale, including their interaction with the surrounding fluid.
