“…This technique permits to get pores through a combination of charged particle bombardment and chemical etching. It allows to control the membrane's pore size and density; the diameter can vary through the thickness of the membrane (Apel et al, 2008). These pores can also be tilted from the surface normal.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. A B S T R A C TNanoporous membranes are used for the elaboration of implantable medical devices. In order to guaranty their integrity after implantation in a patient body, it is necessary to characterize the microstructure and the mechanical behavior of such membranes. They present randomly distributed pores around 1 µm in diameter at the surface. X-ray nanotomography permits to get the geometry of the pores through the thickness with a reduction of the diameter in the core. A multiscale study is done to characterize the membranes: macroscopic tensile tests permit to get the behavior law of the non porous material and in situ tensile tests are carried on in a Scanning Electron Microscope in order to observe the evolution of pores and cracks during loading. A 2D Finite Element Model is also developed in parallel. The confrontation between experiments and numerical simulations permit to validate the accuracy of the model. The latter is then used to simulate several types of loadings considering various pore distributions and sizes.

Low dimensional nanostructures represent a hot scientific field nowadays due mainly to the tremendous potential for applications. Low dimensions open the possibilities for both ultra-miniaturization and increase in functionality. Numerous procedures were developed for fabricating such nanostructures. Template replication represents a highly effective method in fabricating metallic nanowires and nanotubes. The approach is characterized by the excellent control in obtaining nano objects with the desired shape and dimensions. A large variety of templates are available ranging from viruses and proteins to nanoporous membranes fabricated by using swift heavy ion accelerators. In the following chapter the main steps involved

“…Two solid-state pore arrays, polycarbonate pores (readily commercially available) and silicon nitride pores (compatible with standard micro-and nano-fabrication methods) were investigated in this study. The details of fabrication methods for silicon nitride and polycarbonate pores can be found in (Ahmadi and Nair 2013) (Lee et al 2011;Wanunu et al 2009;Zhang et al 2008) and (Apel et al 2006;Apel et al 2008;Karim et al 2009;Nix et al 2009). …”
