Low-temperature magnetic and thermal properties of the frustrated two-dimensional S=1 compound Ni-5(TeO3)(4)Cl-2

The temperature and magnetic field dependent magnetization of the two-dimensional quantum spin system Ni-5(TeO3)(4)Cl-2 has been investigated using single crystals in temperature range 1.8-100 K and in magnetic fields up to 14 T. The magnetization below th ...

Control of a Solid Oxide Fuel Cell System with Biased Gas Temperature Measurements

Daniel Favrat, Jan Van Herle, Leonidas Tsikonis, Joel Albrektsson

An efficient control system is paramount for the operability of Fuel Cell systems since, in ideal cases, it allows the regulation of power output, temperatures and economic performance under a dynamic working environment where they need to operate. Althoug ...

Specification and site control of the permeability of the cover concrete: the Swiss approach

Emmanuel Denarié

It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (covercrete) determine the service life of the structure. S ...

Measuring nanomechanical motion with an imprecision below the standard quantum limit

Tobias Kippenberg, Emanuel Gavartin

We report a room-temperature measurement of nanomechanical motion with an imprecision below the standard quantum limit (SQL), using cavity-enhanced optical near fields. Fundamental thermodynamical cavity frequency fluctuation limits the total imprecision t ...

Nonadiabatic Spin Torque Investigated Using Thermally Activated Magnetic Domain Wall Dynamics

Matthias Alexander Eltschka

Using transmission electron microscopy, we investigate the thermally activated motion of domain walls (DWs) between two positions in Permalloy (Ni80Fe20) nanowires at room temperature. We show that this purely thermal motion is well described by an Arrheni ...

Thermal effects in the Long-Term Monitoring of Bridges

Olivier Burdet

Daily and seasonal temperature variations induce deflections of bridges. The amplitude of these moments is significant in comparison with the yearly increment caused by irreversible long-term deflections. To improve the quality of the interpretation of mon ...

Silicon Resonator Based 3.2 mu W Real Time Clock With +/- 10 ppm Frequency Accuracy

David Ruffieux, François Krummenacher, Aurélie Pezous

This paper presents an ultra-low power generic compensation scheme that is used to implement a real time clock based on an AlN-driven 1 MHz uncompensated silicon resonator achieving 3.2 mu W power dissipation at 1 V and +/- 10 ppm frequency accuracy over a ...

Thermal conductivity of GaAs nanowires studied by micro-Raman spectroscopy combined with laser heating

Anna Fontcuberta i Morral, Emanuele Uccelli

The thermal properties of freely suspended GaAs nanowires are investigated by applying a method which relies on laser heating and the determination of the local temperature by Raman spectroscopy. In order to determine the values for the thermal conductivit ...

Wavelength-tunable UV laser for electron beam generation with low intrinsic emittance

Rasmus Ischebeck, Christoph Peter Hauri

We developed a powerful UV laser at a central wavelength varying from 260-283 nm. The laser system based on a frequency-trippled Ti:sapphire amplifier delivers mJ pulse energy within a duration of 1-10 ps (fwhm) with 1.5 nm spectral width (fwhm). The syste ...

Domain wall contributions in Pb(Zr,Ti)O3 ceramics at morphotropic phase boundary: A study of dielectric dispersion

Dragan Damjanovic, Li Jin, Viktor Porokhonskyy

The dielectric properties of undoped, Nb-, and Fe-doped Pb(Zr,Ti)O3 ceramics with composition near morphotropic phase boundary were investigated in the frequency range from 1 MHz to 20.2 GHz at room temperature. Temperature dependences of dielectric permit ...
