Prediction of solidification behaviour via microstructure models based on granular structures

Michel Rappaz, André Phillion, Stéphane Vernède

Two important factors affecting hot tearing - semi-solid constitutive behaviour and grain percolation - have been simulated through the use of microstructure models based on granular structures. The semi-solid model geometry is based on a modified Voronoi ...

Modeling of mechanical response of FRP composites in fire

Thomas Keller, Yu Bai

A thermomechanical model is presented for predicting the time-dependent deflections of cellular FRP slab elements subjected to mechanical loading and fire from one side. The model comprises temperature-dependent mechanical property sub-models for the Young ...

Modeling and Dynamic Management of 3D Multicore Systems with Liquid Cooling

David Atienza Alonso, José Luis Ayala Rodrigo, Ayse Kivilcim Coskun

Three-dimensional (3D) circuits reduce communication delay in multicore SoCs, and enable efficient integration of cores, memories, sensors, and RF devices. However, vertical integration of layers exacerbates the reliability and thermal problems, and coolin ...

3D-microstructure analysis of hydrated bentonite with cryo- stabilized pore water

Marta Rizzi

In saturated bentonite, free water is hosted in the meso- and macropores. Microscopic characterization of free water and the associated pore structure is very difficult because of the swelling- and shrinking-behaviour of montmorillonite. In this article, w ...

Determination of the thermophysical properties of a CuCr1Zr alloy from liquid state down to room temperature

Jean-Marie Drezet

Laboratory tests and inverse methods are used for the determination of the thermophysical properties of a CuCrZr alloy. The solidification path (temperature versus solid fraction curve) is determined using the Single Pan Thermal Analysis (SPTA) technique d ...

The porous surface model, a novel experimental system for online quantitative observation of microbial processes under unsaturated conditions

Dani Or, Gamze Gülez

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometri ...

Low-dose aberration corrected cryo-electron microscopy of organic specimens

Henning Paul-Julius Stahlberg

Spherical aberration (C-s) correction in the transmission electron microscope has enabled sub-angstrom resolution imaging of inorganic materials. To achieve similar resolution for radiation-sensitive organic materials requires the microscope to be operated ...

Liquid charge transporting material

Michael Graetzel, Shaik Mohammed Zakeeruddin, Henry Snaith

The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of =180 DEG C. In particular in dye-sensitised solar cells, quantum efficiency higher than wi ...

Two-Dimensional Magnetic Droplet Manipulation Platform for Miniaturized Bioanalytical Applications

Martinus Gijs, Ulrike Lehmann, Virendra Kumar Parashar, Caroline Vandevyver

We present a new approach for the manipulation of small liquid samples for the miniaturization of bioanalytical systems. In our system, minute liquid volumes are manipulated via the interaction of a changeable magnetic field and magnetic microparticles con ...

Structural properties of amorphous GeSe2

Alfredo Pasquarello

By using first-principles molecular dynamics within density functional theory, we study the structural properties of amorphous GeSe2 at T = 300 K. The amorphous configurations have been obtained via cooling from the liquid state followed by extensive relax ...
