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 ...
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 ...
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 ...
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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
