To grate a liquid into tiny droplets by its impact on a hydrophobic microgrid

P. Brunet, F. Lapierre, Farzam Zoueshtiagh, V. Thomy, A. Merlen

We report on experiments of drop impacting a hydrophobic micro-grid, of typical spacing a few tens of µm. Above a threshold in impact speed, liquid emerges to the other side, forming microdroplets of size about that of the grid holes. We propose a method to produce either a mono-disperse spray or a…

Universality of bias- and temperature-induced dephasing in ballistic electronic interferometers

Y. Yamauchi, M. Hashisaka, S. Nakamura, K. Chida, S. Kasai, T. Ono, R. Leturcq, K. Ensslin, D.C. Driscoll, A.C. Gossard, K. Kobayashi

We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-P´erottype interferometer. In both cases we found that the interference signal is reversed at a certain bias voltage and that the visibility decays exponentially as a function of temperature, being in a strong…

A millimeter-wave microstrip antenna array on ultra-flexible micromachined polydimethylsiloxane (PDMS) polymer

S. Hage-Ali, Nicolas Tiercelin, P. Coquet, R. Sauleau, H. Fujita, Vladimir Preobrazhensky, Philippe Pernod

The use of Polydimethylsiloxane (PDMS), an ultra flexible polymer, as a substrate for the realization of reconfigurable microwave devices in the 60-GHz band is presented. As bulk PDMS is demonstrated to be lossy at millimeter waves, membrane-supported devices are considered. A new reliable and…

Synthesis and luminescence properties of (N-Doped) ZnO nanostructures from a dimethylformamide aqueous solution

B. Sieber, Hong Liu, G. Piret, J. Laureyns, P. Roussel, B. Gelloz, Sabine Szunerits, Rabah Boukherroub

The paper reports on the optical properties of ZnO nanostructures elaborated on a zinc foil substrate by a simple chemical approach. The doping type and density of the ZnO nanostructures were evaluated using electrochemical impedance spectroscopy. XRD diffraction patterns and Raman spectroscopy…

Electrochemical impedance spectroscopy of ZnO nanostructures

Hong Liu, G. Piret, B. Sieber, J. Laureyns, P. Roussel, Wei-Jiang Xu, Rabah Boukherroub, Sabine Szunerits

The paper reports on the use of electrochemical impedance spectroscopy to determine the doping character and carrier density of freshly prepared and annealed ZnO nanostructures. The ZnO nanostructures were obtained by chemical oxidation of metallic Zn in a 5% N,N-dimethylformamide (DMF) aqueous…

Experimental study on sound and damaged mortar: Variation of ultrasonic parameters with porosity

Zoubeir Lafhaj, Marc Goueygou

The relationship between porosity and ultrasonic parameters of mortar was studied. In order to enhance the sensitivity of the ultrasonic wave to microstructural changes, a high frequency range, 0.6–1.2 MHz, was chosen. The material investigated consists of four mortar mixtures with water/cement…
