Abstract：

It  has become important the mechanical characterization of small volumes of solids  as the focus in materials science shifts towards designing devices at the  submicron scale; for instance the development of microelectromechanicaland  nanoelectromechanical systems. The development of ultrasensitive transducers of  precise geometry for sensing force and depth have made such measurements  possible. There are commercial instruments, like the TriboScope ©, which are  adaptable and easy to install onto widely apparatus, like NanoScope SPM© . These  instuments have the capability to take nanoindentation measurements  with in situ imaging. As an application of this technique, hardness  and reduced elastic modulus of hard coatings and human teeth are  presented.

Speaker’s  Short Bio:

Enrique  C. Samano earned hisPhD degree in Physics fromStevens Institute of Technologyin  Hoboken, NJ, USA, in1992. He is a ResearchProfessor at Centro deNanocienciasy  Nanotecnología(CNyN) of the National University of México (UNAM) in Ensenada,  Baja California, Mexico, working on surface science and, lately on DNA  Nanotechnology. Ha is  involvedon the fabrication of nanostructuresbased on  DNA with applications in electronics andplasmonics. He has been a vising  professor at University of Southern California and Duke University. Ha has  published around 35 articles in international indexed journals and 3 chapters in  books.
