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 ...

Extreme temperature sensing using Brillouin scattering in optical fibers

Alexandre Fellay

Stimulated Brillouin scattering in silica-based optical fibers may be considered from two different and complementary standpoints. For a physicist, this interaction of light and pressure wave in a material, or equivalently in quantum theory terms between p ...

Towards a room-temperature polariton amplifier

Benoît Marie Joseph Deveaud, Stefan Kundermann, Cristiano Ciuti, Michele Saba

Microcavity exciton polaritons, the fundamental optical excitations of semiconductor microcavities with quantum wells inside, have been proposed as promising candidates for observing stimulated scattering, condensation and other phenomena related to the bo ...

Automatic Monitoring of the Riddes Bridges using Electronic Inclinometers

Olivier Burdet

The paper presents an innovative method of measurement of long-term deformations of bridges. The use of high precision electronic inclinometers permits an efficient and cost-effective automatic monitoring of bridge deformations. The system is easily applic ...

Dynamics of surface migration in the weak corrugation regime

Klaus Kern, Harald Brune

We report a systematic study for metal-on-metal surface migration in the weak corrugation regime, i.e., with migration barriers falling below approximate to 100 meV. The migration characteristics are elucidated by variable-temperature scanning tunneling mi ...

TEMPERATURE DIAGNOSTICS FOR LASER WRITING

René Salathé

Infrared (IR), Raman, and luminescence measurements are discussed with respect to their application as temperature probe during laser writing. IR measurements on the high energy side of the Planck distribution can be applied to a large variety of materials ...

Calorimetric validation of TLD-measured gamma-heating effects

Rakesh Chawla

The use of TLDs for the determination of gamma-heating effects in various materials, spanning a Z-number range of ~4-82, has been assessed in the light of temperature measurements across specially designed experimental assemblies. A large planar 60Co sourc ...
