We explore the generation of charge and valley polarized unidirectional transport in graphene bilayers [1]. With this aim we build on previous proposals [2,3] and show how one-way ambipolar charge and valley transport can be achieved in graphene bilayers under experimentally feasible conditions. Furthermore we analyze the valley polarization robustness among the presence of intervalley scattering in the system. The second part of the talk would focus on the topological states in ?metal-organic frameworks? and the chances of detecting them [4]. [1] M. Berdakin, J. E. Barrios Vargas, L. E. F.
