Experimental investigation on temperature-dependent thermo- physical and mechanical properties of pultruded GFRP composites

The temperature-dependent thermo-physical and mechanical properties of a pultruded E-glass fiber-reinforced polyester (GFRP) composite are investigated in this paper. Fitting of theoretical models of the material properties to results of TGA, DSC, hot disk ...

Boiling on a tube bundle

Francesco Agostini

The complexity of the two-phase flow in a tube bundle presents important problems in the design and understanding of the physical phenomena taking place. The working conditions of an evaporator depend largely on the dynamics of the two-phase flow that in t ...

A methodology to select the experimental plant instrumentation based on an a priori analysis of measurement errors and instrumentation cost

John Richard Thome

An experimental apparatus for evaluating carbon dioxide local heat transfer coefficients during flow boiling has been set up at University of Naples Federico II. In this paper, the local heat transfer coefficient measured is evaluated relative to the measu ...

Transport and magnetic properties of BaVSe3

László Forró, Helmuth Berger, Ana Akrap, Vladan Stevanovic, Neven Barisic

We report a comprehensive study of transport, magnetotransport, and magnetic properties of single crystals of BaVSe3. The paramagnetic metal-ferromagnetic metal transition at 43 K was followed as a function of pressure by measuring the electrical resistivi ...

INFLUENCE OF THE SATURATION TEMPERATURE ON THE HEAT TRANSFER COEFFICIENT FOR FLOW BOILING INSIDE HORIZONTAL SMOOTH TUBES

John Richard Thome, Ricardo Lima

This article presents experimental results of heat transfer from two different studies [1, 2] for horizontal flow boiling inside smooth copper tubes with different refrigerants. The main goal of this study was to verify the influence of the saturation temp ...

First-principles study of Fe and FeAl defects in SiGe alloys

Alexandra Sarabando de Carvalho

First-principles, spin-polarized local-density-functional calculations are used to model interstitial iron (Fei) and its complexes with substitutional aluminum in dilute SixGe1−x alloys (x

Thermopower measurements on pentacene transistors

Libero Zuppiroli, Marie-Noëlle Bussac, Adrian von Mühlenen

We present the first thermoelectric measurements on pentacene field effect transistors. We report high values of the Seebeck coefficient at room temperature between 240 and 500 micro V/K depending on the dielectric surface treatment. These values are indep ...

Spin mixing processes in magnetic nanostructures detected by thermoelectric measurements

Jean-Philippe Ansermet, Santiago Serrano Guisan, Giulia Di Domenicantonio

Spin-dependent transport properties of magnetic nanostructures have been investigated by means of magneto-thermogalvanic voltage measurements: the ac voltage response to an ac temperature oscillation is measured for various magnetic nanostructures under dc ...

Ni-doped cobaltates as potential materials for high temperature solar thermoelectric converters

Balazs Sipos

Thermoelectric properties of Ni substituted (La) cobaltate compounds with perovskite structure have been investigated. For all the studied compounds the Seebeck coefficient is positive indicating predominant positive charge carriers. The electrical resisti ...

Spin-dependent transport in cluster-assembled nanostructures: influence of cluster size and matrix material

Jean-Philippe Ansermet, Santiago Serrano Guisan, Giulia Di Domenicantonio

Spin-dependent transport in granular metallic nanostructures has been investigated by means of a thermoelectric measurement. Cobalt clusters of well-defined size ( = 15 and 600), embedded in copper and silver matrices, show magnetic field responses of u ...
