Experimental method to characterize the strain dependent permeability of tissue engineering scaffolds

Dominique Pioletti, Naser Nasrollahzadeh Mamaghani

Permeability is an overarching mechanical parameter encompassing the effects of porosity, pore size, and interconnectivity of porous structures. This parameter directly influences transport of soluble particles and indirectly regulates fluid pressure and v ...

Structured and porous materials particularly suitable as polarizing agents in dissolution dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, David Benjamin Roger Antoine Gajan, David Baudouin

The present invention concerns materials consisting in a porous and structured network, this network being at least in part formed by Si atoms, or Si atoms and metal atoms, linked to each other by oxy bridges, comprising organic molecules which include at ...

Hydro-chemo-mechanical characterisation of sand/bentonite mixtures

Donatella Manca

According to Swiss regulations, low and intermediate level wastes (L/ILW) should be stored in deep geological repositories excavated about 300 to 400 meters below the ground surface, in suitable rock formations. The materials used for the construction of t ...

Dilatant hardening of fluid-saturated sandstone

Roman Makhnenko

The presence of pore fluid in rock affects both the elastic and inelastic deformation processes, yet laboratory testing is typically performed on dry material even though in situ the rock is often saturated. Techniques were developed for testing fluid-satu ...

Influences of porous reservoir Laplace pressure on emissions from passively fed ionic liquid electrospray sources

Herbert Shea, Daniel George Courtney

Passively fed ionic liquid electrospray sources are capable of efficiently emitting a variety of ion beams with promising applications to spacecraft propulsion and as focused ion beams. Practical devices will require integrated or coupled ionic liquid rese ...

Autogenous Shrinkage and Hydration Kinetics of SH-UHPFRC under Moderate to Low Temperature Curing Conditions

Mohammadhadi Kazemi Kamyab

Strain Hardening Ultra High Performance Fiber Reinforced Concrete (SH-UHPFRC) were used successfully over the last 8 years in numerous cast in place rehabilitation applications as long lasting waterproofing layers (20 to 30 mm thickness) and, combined with ...

Influence of the meso-structure in dynamic fracture simulation of concrete under tensile loading

Jean-François Molinari, Leonardo Snozzi

We investigate the dynamic behavior of concrete in relation to its composition within a computational framework (FEM). Concrete is modeled using a meso-mechanical approach in which aggregates and mortar are represented explicitly. Both continuum phases are ...

Hydro-mechanical coupling in the periodontal ligament: A porohyperelastic finite element model

Matteo Galli, Joël Cugnoni, Marzio Bergomi

Harmonic tension–compression tests at 0.1, 0.5 and 1 Hz on hydrated bovine periodontal ligament (PDL) were numerically simulated. The process was modeled by finite elements (FE) within the framework of poromechanics, with the objective of isolating the con ...

A combination of the Hashin-Shtrikman bounds aimed at modelling electrical conductivity and permittivity of variably saturated porous media

Alessandro Brovelli

In this paper we propose a novel theoretical model for the dielectric response of variably saturated porous media. A model is constructed for fully saturated porous media as a combination of the well established Hashin and Shtrikman [1962] bounds and Archi ...

Friction factor correlation for CICC's based on a porous media analogy

Luca Bottura

We use an analogy to porous media to derive a correlation for the friction factor in CICC s We start with a review of selected literature work on this topic We then recall the principles of the porous medium analogy and present the main body of our work on ...
