On the behavior of uniaxial static stress loaded micro-scale fused silica beams at room temperature

Yves Bellouard, Christos Edouardos Athanasiou, Saood Ibni Nazir

The question of whether static stress in fused silica relaxes at room temperature is still under debate. Here, we report experimental data investigating the behavior of fused silica at room temperature when subjected to static tensile stress up to 2 GPa st ...

Monitoring Spontaneous Charge-Density Fluctuations by Single-Molecule Diffraction of Quantum Light

Homodyne X-ray diffraction signals produced by classical light and classical detectors are given by the modulus square of the charge density in momentum space vertical bar sigma(q)vertical bar(2), missing its phase, which is required in order to invert the ...

From rock to magma and back again: The evolution of temperature and deformation mechanism in conduit margin zones

Marie Estelle Solange Violay, Michael Heap

Explosive silicic volcanism is driven by gas overpressure in systems that are inefficient at outgassing. The zone at the margin of a volcanic conduit-thought to play an important role in the outgassing of magma and therefore pore pressure changes and explo ...

Mechanical behaviour of diamond reinforced metals

Ludger Weber, Reza Tavangar Hamzehkolaei

Diamond reinforced metals with a diamond content of 55-60 vol.% were made by gas driven liquid metal infiltration. They were characterized with regard to their stiffness, strength and fracture toughness as a function of diamond particle size and matrix all ...

Stress control in GaN/sapphire templates for the fabrication of crack-free thick layers

Nicolas Grandjean, Marc Ilegems, Denis Martin

The reduction of the tensile stress contained in GaN layers grown oil sapphire by metalorganic vapor phase epitaxy (MOVPE) is achieved using a low density of initial GaN crystallites. The template layers exhibit a significant reduction in dislocation densi ...

Hydrogenation of C60 at 2GPa pressure and high temperature

Yury Tsybin

Hydrogenation of C60 at 2 GPa and 723-823 K was performed with thermal decompn. of LiAlH4 as a hydrogen source. Anal. of hydrogenation products showed that the method can produce not only C60H36, but also hydrofullerides C60Hx with 44 < x < 52. Unlike othe ...

A multi-domain Chebyshev collocation method for predicting ultrasonic field parameters in complex material geometries

Jan Sickmann Hesthaven

The use of ultrasound to measure elastic field parameters as well as to detect cracks in solid materials has received much attention, and new important applications have been developed recently, e.g., the use of laser generated ultrasound in non-destructiv ...

Short-Term biomechanical adaptation of the rat carotid to acute hypertension: contribution of smooth muscle

Nikolaos Stergiopoulos, Jean-Jacques Meister

The biomechanical adaptation of the arterial wall to hypertension has been studied extensively in recent years; however, the exact biomechanical contribution of vascular smooth muscle cells (VSMCs) during the adaptation process in conduit vessels is not kn ...

Microscopic anharmonicity and equation of state of MgSiO3- perovskite

Philippe Gillet

The effect of temperature on the Raman spectrum of MgSiO3-perovskite is investigated between 77 and 300 K. The data, combined with those obtained at high pressure, are used to infer microscopic anharmonic parameters (a(i)) It is shown that only two low-fre ...

UN CRITERIO DI DIMENSIONAMENTO DELLE PROTEZIONI DI FONDO IN BACINI DI DISSIPAZIONE

Andrea Rinaldo

Analytical solutions for space and time evolution of uplift pressures acting on the impervious lining of stilling basins are obtained. Uplift variations are forced by random fluctuating pressures generated by a hydraulic jump. The model, aimed at portrayin ...
