MECHANICAL SPECTROSCOPY OF ORDERED BINARY Au-Cu

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

We have studied a binary Au-Cu single crystal by mechanical spectroscopy. Upon very slow cooling from high temperatures, additional relaxation peaks arise at lower frequencies in isothermal spectra after the disappearing of the Zener peak below 665 K due t ...

Functional group distribution of secondary organic aerosol generated using the Master Chemical Mechanism: similarities and discrepancies with environmental controlled chamber studies

Satoshi Takahama, Giulia Ruggeri, Fabian Alexander Bernhard, Sarah Elizabeth Shipley

In this work, composition of organic aerosol simulated by the Master Chemical Mechanism coupled with a dynamic absorptive partitioning model is compared against infrared spectroscopy measurements of functional group abundance in chamber experiments. The Ma ...

High pressure phase transition in FeTe2O5Cl

Helmuth Berger

Raman and optical absorption spectra of FeTe2O5Cl at pressures (P) up to 5.9 GPa were measured in order to identify the point of pressure-induced structural phase transition and to compare the vibrational and optical properties of FeTe2O5Cl to those of FeT ...

, ,

The spectroscopy of amide I vibrations has become a powerful tool for exploring protein structure and dynamics. To help with spectral interpretation, it is often useful to perform molecular dynamics (MD) simulations. To connect spectroscopic experiments to ...

American Institute of Physics2014

Silicon nitride based ceramics (SiAlONs); tetragonal polycrystalline zirconia (3Y‐TZP); alumina and their composites reinforced with different amount of multi‐ walled carbon‐nanotubes (CNTs) have been processed by Spark Plasma Sintering (SPS). High tempera ...

The metastable HCl center dot 6H(2)O phase - IR spectroscopy, phase transitions and kinetic/thermodynamic properties in the range 170-205 K

Michel Rossi, Simone Chiesa

In this laboratory study a multidiagnostic experimental approach including Fourier transform infrared (FTIR) absorption of 1 to 2 mu m thick polycrystalline ice films, residual gas mass spectrometry (MS) and total pressure measurement were employed. Both a ...

Hyperbolic spin vortices and textures in exciton-polariton condensates

Benoît Marie Joseph Deveaud, Francesco Manni

From cosmology to the microscopic scales of the quantum world, the study of topological excitations is essential for the understanding of phase conformation and phase transitions. Quantum fluids are convenient systems to investigate topological entities be ...

High temperature transformations in a steel-TiCN cermet

Daniele Mari

The influence of the carbon content on the microstructure, phase transformation and hardness of an iron-based cermet is studied. The cermet is constituted by a high-alloyed steel as matrix, and TiCN particles (50 vol.%) as reinforcement. The material is pr ...

Tensor network study of the Shastry-Sutherland model in zero magnetic field

Frédéric Mila

We simulate the Shastry-Sutherland model in two dimensions by means of infinite projected entangled-pair states (iPEPS)-a variational tensor network method where the accuracy can be systematically controlled by the so-called bond dimension. Besides the wel ...

2013

Thermally sprayed hardmetal coatings can be used to improve the wear or fatigue resistance of mechanical parts. Depending on the deposition conditions, their microstructure and phase composition are out of equilibrium at different levels due to the extreme ...
