  1. Simultaneous existence of phononic and photonic band gaps in periodic crystal slabs

    Pennec, Y.; Rouhani, B. Djafari; El Boudouti. E. H.; Li, C.; El Hassouani, Y.; Vasseur, J. O.; Papanikolaou, Nikos; BENCHABANE, SAMIR; LAUDE, VINCENT; Martínez Abietar, Alejandro José
    We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell which include the simple square, triangular and honeycomb lattices as particular cases. We show that complete phononic and photonic band gaps can be obtained from the honeycomb lattice as well as BN lattices close to honeycomb. Otherwise, all investigated structures present the possibility of a complete phononic gap together with a photonic band gap of a given...

  2. Ambient and fire behavior of eccentrically loaded elliptical slender concrete-filled tubular columns

    Espinós Capilla, Ana; Romero, Manuel L.; Portolés Flag, Jose Manuel; Hospitaler Pérez, Antonio
    This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behavior of such innovative cross-sections under ambient and high temperatures. The test parameters covered in this experimental program were the load eccentricity (0, 20 and 50 mm) and the type of infill (plain concrete or bar-reinforced concrete). Six room temperature tests were performed, while other six tests were carried out at...

  20. Structured fibrous carbon-based catalyst for continuous nitrate removal from natural water

    Yuranova, T.; Franch Martí, Cristina; Palomares Gimeno, Antonio Eduardo; García-Bordejé, E.; Kiwi-Minsker, L.
    Bimetallic (Pd–Cu, Pd–Sn) nanoparticles supported on structured fibrous carbons (activated carbon fibers and carbon nanofibers grown on sintered metal fibers) were tested in nitrate removal of natural polluted water by hydrogen (a batch and continuous mode). Dependence of the activity/selectivity on catalyst chemical composition, promoter nature and metal particle size was studied. Sn-modified Pd nanoparticles showed higher N2 selectivity as compared to Cu-modified ones. The structured (Pd–Sn) nanoparticles supported on carbon nanofibers grown on Inconel sintered metal fibers demonstrated the best catalytic performance in an open flow reactor, providing optimal hydrodynamics properties.
