Comparative oxidation behavior of columnar and equiaxed Cr2AlC coatings

The oxidation behavior of columnar and equiaxed Cr2AlC coatings in air at 990 °C is studied. During the transient heating-up period to 990 °C the two coating morphologies exhibit different oxidation behavior. In columnar coatings, faster Al diffusion along ...

Refractive Index Matched (RIM) PIV in Free Surface Flows of Particle-Laden Yield Stress Fluids

Christophe Ancey, Yanan Chen

Flow of lava, avalanches, mudslides, and many geophysical and planetary flow systems are examples of free-surface flows of Yield Stress Fluids (YSFs). This category of fluids is known for its dual behavior below- and above a yielding threshold for the appl ...

Improved Material Formulations for Thick Adhesive Joints in Wind Turbine Blades

Jialiang Fan

Wind turbine rotor blades are usually fabricated using composite materials and epoxy adhesive to bond the elements together. Due to their large size, the thickness of the adhesive layer varies from 1 to up to 30 mm depending on the position. The failure of ...

Wigner Formulation of Thermal Transport in Solids

Nicola Marzari, Michele Simoncelli

Two different heat-transport mechanisms are discussed in solids. In crystals, heat carriers propagate and scatter particlelike as described by Peierls's formulation of the Boltzmann transport equation for phonon wave packets. In glasses, instead, carriers ...

Active microrheology in corrugated channels: Comparison of thermal and colloidal baths

Ignacio Pagonabarraga Mora

Hypothesis: The dynamics of colloidal suspension confined within porous materials strongly differs from that in the bulk. In particular, within porous materials, the presence of boundaries with complex shapes entangles the longitudinal and transverse degre ...

A Mixed-Integer Linear Programming Formulation for Optimizing Multi-Scale Material and Energy Integration

François Maréchal, Ivan Daniel Kantor, Hür Ebuzer Bütün, Jean-Loup Sylvain Robineau

This research presents a mathematical formulation for optimizing integration of complex industrial systems from the level of unit operations to processes, entire plants, and finally to considering industrial symbiosis opportunities between plants. The fram ...

Microstructural controls of anticrack nucleation in highly porous brittle solids

Johan Alexandre Philippe Gaume, Henning Löwe

Porous brittle solids have the ability to collapse and fail even under compressive stresses. In fracture mechanics, this singular behavior, often referred to as anticrack, demands for appropriate continuum models to predict the catastrophic failure. To ide ...

Out-of-equilibrium dynamical equations of infinite-dimensional particle systems I. The isotropic case

Elisabeth Agoritsas

We consider the Langevin dynamics of a many-body system of interacting particles in d dimensions, in a very general setting suitable to model several out-of-equilibrium situations, such as liquid and glass rheology, active self-propelled particles, and gla ...

Kinetic approach to the Schwinger effect during inflation

Oleksandr Sobol

Using the kinetic approach, we study the impact of the charged particle dynamics due to the Schwinger effect on the electric field evolution during inflation. As a simple model of the electric field generation, we consider the kinetic coupling of the elect ...

Rheological behavior of colloidal suspension with long-range interactions

In this work, we study the constitutive behavior of interacting colloidal suspensions for moderate and high concentrations. Specifically, using a lattice Boltzmann solver, we numerically examine suspensions flowing through narrow channels, and explore the ...

Scaling description of non-local rheology

Matthieu Wyart

The plastic flow of amorphous materials displays non-local effects, characterized by a cooperativity length scale xi. We argue that these effects enter in the more general description of surface phenomena near critical points. Using this approach, we obtai ...

Agent-Based Routing in Queueing Systems

Olivier Gallay

Waiting time in any network is often a costly and hence a bad experience. Therefore, to avoid jamming regions becomes essential in the optimization of traffic flows. In this regard, the conception and the control of complex networks supporting flows of uni ...

The in vivo performance of magnetic particle-loaded injectable, in situ gelling, carriers for the delivery of local hyperthermia

Heinrich Hofmann, Alke Fink, Antonin Faes

In situ forming implants are attractive for minimally invasive localized therapies such as aneurysm embolization. As for the superparamagnetic iron oxide nanoparticles (SPIONs), their deposition/injection in a target tissue area allows magnetically induced ...

Influence of the constant life diagram formulation on the fatigue life prediction of composite materials

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

The influence of the constant life diagram (CLD) formulation on the fatigue life prediction of composite materials was examined. Most commonly used and recently proposed CLDs applied on composite materials fatigue data are presented and their applicability ...

Photo-polymerization, swelling and mechanical properties of cellulose fibre reinforced poly(ethylene glycol) hydrogels

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

The application of hydrogels as load-bearing biomedical components is often limited by their mechanical properties. Often an attempt to improve a hydrogel's stiffness is accompanied by a loss of toughness and swelling properties. In this work, we show that ...

Introducing symmetry conditions in the integral equation technique applied to quasi-waveguide structures

Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad

Integral Equation (IE) formulation solved by Method of Moments may be used efficiently to address the problem of quasi-waveguide structures, i.e. structures consisting of a main waveguide with a constant cross section that may bear an arbitrary number of p ...

Three-dimensional harmonic holographic microcopy using nanoparticles as probes for cell imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...

Discrete dislocation modeling of fracture in plastically anisotropic metals
