Structural modifications of GeO glass under high pressure and high temperature
Antoine Cornet, Remy Molherac, Bernard Champagnon +1
Vitreous GeO has been compressed at high temperature, to investigate the effect of thermal activation on the structural reorganization during compression. The measurements were…
Determination of compressive stress in thin films using micro-machined buckled membranes
C. Malhaire, M. Granata, D. Hofman +5
In this work, optical profilometry and finite-element simulations are applied on buckled micro-machined membranes for the stress analysis of ion-beam-sputtered $\mathrm{Ta_{2}O_{5}…
Bi-modal photothermal/optical microscopy for complementary bio-imaging with high resolution and contrast
Sergiy Litvinenko, Pavlo Lishchuk, Vladimir Lysenko +1
In the paper, combined bimodal microscopic visualization of biological objects based on reflection-mode optical and photoacoustic measurements was presented. Gasmicrophone configur…
Analytical model of the acoustic response of nanogranular films adhering on a substrate
Gianluca Rizzi, Giulio Benetti, Claudio Giannetti +2
A 1D mechanical model for nanogranular films, based on a structural interface, is here presented. The analytical dispersion relation for the frequency and lifetimes of the acoustic…
