Mechanical spectroscopy in carbon nanotube reinforced ABS

Mechanical spectroscopy has been used to qualify possible improvements of the mechanical properties of acrylonitrile-butadiene-styrene-carbon nanotubes (ABS-CNTs) composites. The properties of ABS matrix are first investigated. Two relaxations that mark th ...

High temperature mechanical spectroscopy of fine-grained zirconia and alumina containing nano-sized reinforcements

Claudia Ionascu

Polycrystalline zirconia (3Y-TZP grade) unreinforced and reinforced with multiwalled carbon nanotubes (CNTs) or silicon carbide whiskers (SiCw) or silicon carbide particles (SiCp) have been processed and studied by mechanical spectroscopy with complementar ...

Thermally activated solvent bonding of polymers

Nico de Rooij

We present a thermally activated solvent bonding technique for the formation of embedded microstructures in polymer. It is based, on the temperature dependent solubility of polymer in a liquid that is not a solvent at room temperature. With thermal activat ...

High-pressure infrared spectroscopy: Tuning of the low-energy excitations in correlated electron systems

László Forró, Richard Gaal, Balazs Sipos, Helmuth Berger

We have extended the range of the high-pressure optical spectroscopy to the far-infrared region keeping the accuracy of ambient-pressure experiments. The developed method offers a powerful tool for the study of pressure-induced phase transitions and electr ...

Pressure-Induced Chemical Decomposition and Structural Changes of Boric Acid

Philip Pattison, Vladimir Dmitriev

A combined synchrotron X-ray diffraction, Raman scattering, and infrared spectroscopy study of the pressure-induced changes in H3BO3 to 10 GPa revealed a new high-pressure phase transition between 1 and 2 GPa followed by chemical decomposition into cubic H ...

Mechanical spectroscopy of Al-Cu-Fe quasicrystalline coatings

Robert Schaller, Nadine Baluc

Since the bulk Al-Cu-Fe quasicrystals are extremely brittle below 700 K, a quasicrystalline coating deposited on a steel substrate by thermal spraying was used for mechanical spectroscopy measurements at temperatures in the range of 300-800 K. The internal ...

Mechanical spectroscopy of decagonal Al-Cu-Fe-Cr quasicrystalline coatings

Robert Schaller, Nadine Baluc

Mechanical spectroscopy measurements were performed on decagonal quasicrystalline Al-Cu-Fe-Cr coatings of three different thicknesses deposited on a mild steel substrate. The mechanical loss spectra indicate that the internal friction is mostly caused by t ...

High temperature deformation mechanisms of cemented carbides and cermets

The motivation of this work derives from the need of the cutting tool industry to improve its products in order to support harder and harder working conditions, namely increasing cutting speeds and working on stronger modern materials. The lifetime of the ...

Al-Cu-Fe quasicrystalline coatings and composites studied by mechanical spectroscopy

Mechanical spectroscopy measurements were performed on two types of materials: decagonal quasicrystalline Al-Cu-Fe-Cr coatings deposited on a mild steel substrate and aluminium or magnesium matrix composites reinforced with icosahedral quasicrystalline Al- ...

Direct observation of new transitions in the absorption spectra of a V-groove quantum wire waveguide

Elyahou Kapon, Alok Rudra, Marc-André Dupertuis, Daniel Oberli, Klaus Leifer

We report on the direct absorption measurement of the polarization selection rules in a V-groove QWR waveguide. Attenuation measurements in a 1 mm long waveguide were performed from 10 K up to room temperature. These measurements yielded the QWR DOS select ...
