Quasi-steady and steady states in global gyrokinetic particle-in-cell simulations

Laurent Villard, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Paolo Angelino, Thibaut Vernay

Collisionless delta-f gyrokinetic particle-in-cell simulations suffer from the entropy paradox, in which the entropy grows linearly in time while low-order moments are saturated. As a consequence, these simulations do not reach a steady state and are unsui ...

Vibrational contributions to the stability of point defects in bcc iron: A first-principles study

Robin Schäublin, Guillaume Lucas

The purpose of this study is to investigate the modes of vibration of the self-interstitial atoms and the vacancy in bcc iron and to estimate how the vibrational properties can affect the stability of these defects. The phonon density of states of the vaca ...

Electronic origin of the isostructural decomposition in cubic M1-xAlxN (M=Ti, Cr, Sc, Hf): A first-principles study

Alireza Karimi

We have used first-principles calculations to investigate the mixing enthalpies, lattice parameters and electronic density of states of the ternary nitride systems Ti1-xAlxN, Cr1-xAlxN, Sc1-xAlxN and Hf1-xAlxN in the cubic B1 structure where the transition ...

Experimental and theoretical investigations of the thermodynamic stability of Ba-C-60 and K-C-60 compound clusters

Klaus Kern

A novel experimental set-up was used to study superstable (magic) Ba-C-60 and K-C-60 compound clusters. The most stable systems observed cannot be rationalized by simple electronic or by geometrical shell filling arguments. Annealing the clusters past the ...

Genome-scale thermodynamic analysis of Escherichia coli metabolism

Vassily Hatzimanikatis

Genome-scale metabolic models are an invaluable tool for analyzing metabolic systems as they provide a more complete picture of the processes of metab. The authors have constructed a genome-scale metabolic model of Escherichia coli based on the iJR904 mode ...

Processing of porous polymer composites for bone tissue engineering

Bone is a natural cellular composite, with a gradient structure going from a loose interconnected core to an outer dense wall, thus minimising bone weight while maintaining a high mechanical performance. Bone can be repaired using either auto- or allo- gra ...

Hyperbranched Polymer/Montmorillonite Clay Nanocomposites

Yves Leterrier, John Christopher Plummer, Marlene Rodlert

Two to four pseudo-generation aliphatic hyperbranched polymers (HBPs) with OH end-groups have been solution processed with various types of montmorillonite (MMT) layered alumino-silicate clays, and carefully dried to produce solid HBP/MMT nanocomposites. ...

Entropy-based Multi-stream Combination

Hervé Bourlard, Hemant Misra, Vivek Tyagi

Full-combination multi-band approach has been proposed in the literature and performs well for band-limited noise. But the approach fails to deliver in case of wide-band noise. To overcome this, multi-stream approaches are proposed in literature with varyi ...

Electron diffraction and high resolution transmission electron microscopy in the characterization of calcium phosphate precipitation from aqueous solutions under biomineralization conditions

Philippe Buffat, Elena Suvorova Buffat

Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...

Calcium phosphate precipitation under biomineralization conditions: Effect of microgravity

Elena Suvorova Buffat

Structure and morphology of solid particles in precipitation from aqueous solutions correlate with formation (solution) conditions and thus reflect the growth mechanism. Calcium phosphate precipitation obtained from dilute aqueous solutions at room and bod ...
