Inline high frequency ultrasonic particle sizer

Fabrice Lefebvre, J. Petit, Georges Nassar, P. Debreyne, Guillaume Delaplace, Bertrand Nongaillard

This paper reports the development of a new method of particle sizing in a liquid. This method uses high frequency focused ultrasounds to detect particles crossing the focal zone of an ultrasonic sensor and to determine their size distribution by processing the reflected echoes. The major advantage…

Numerical investigation of the functionally graded materials by the interaction of the plate guided waves with discontinuities and cracks

Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

This work intends to give a better comprehension of the guided wave interactions with damage in a functionally graded material (FGM). For this purpose, a two dimensional finite element (FE) method is used to analyse the near field surrounding the damage. Then, the expansion of the solution into…

Structure and mechanical characterization of DNA i-motif nanowires by molecular dynamics simulation

R.P. Singh, R. Blossey, F. Cleri

We studied the structure and mechanical properties of DNA i-motif nanowires by means of molecular dynamics computer simulations. We built up to 230 nm-long nanowires, based on a repeated TC5 sequence from crystallographic data, fully relaxed and equilibrated in water. The unusual C⋅C+ stacked…

Approach-to-equilibrium molecular dynamics to study thermal transport

Evelyne Lampin, Pier Luca Palla, Pierre-Arnaud Francioso, Fabrizio Cleri

We study thermal transport properties by conduction using molecular dynamics simulations. In our approach, two portions are delimited and heated at two different temperatures before the approach-to-equilibrium in the whole structure is monitored. The observed decay of the temperature difference is…

Defect-controlled hypersound propagation in hybrid superlattices

D. Schneider, F. Liaqat, E.H. El Boudouti, O. El Abouti, W. Tremel, H.J. Butt, Bahram Djafari-Rouhani, G. Fytas

We employ spontaneous Brillouin light scattering spectroscopy and detailed theoretical calculations to reveal and identify elastic excitations inside the band gap of hypersonic hybrid superlattices. Surface and cavity modes, their strength and anticrossing are unambiguously documented and fully…
