Large-scale epitaxy of two-dimensional van der Waals room-temperature ferromagnet Fe5GeTe2
Mário Ribeiro, Giulio Gentile, Alain Marty +12
In recent years, two-dimensional van der Waals materials have emerged as an important platform for the observation of long-range ferromagnetic order in atomically thin layers. Alth…
Solvent and salt effect on Lithium ion solvation and contact ion pair formation in organic carbonates: a quantum chemical perspective
Veerapandian Ponnuchamy, Stefano Mossa, Ioannis Skarmoutsos
Quantum chemical calculations have been employed to investigate the solvation of lithium cations in ethylene carbonate/propylene carbonate and propylene carbonate/dimethyl carbonat…
Elastic heterogeneity, vibrational states, and thermal conductivity across an amorphisation transition
Hideyuki Mizuno, Stefano Mossa, Jean-Louis Barrat
Disordered solids exhibit unusual properties of their vibrational states and thermal conductivities. Recent progresses have well established the concept of "elastic heterogeneity",…
Inhomogeneous transport in model hydrated polymer electrolyte supported ultra-thin films
D. Damasceno Borges, A. A. Franco, K. Malek +2
Structure of polymer electrolytes membranes, e.g., Nafion, inside fuel cell catalyst layers has significant impact on the electrochemical activity and transport phenomena that dete…
Measuring Spatial Distribution of Local Elastic Modulus in Glasses
Hideyuki Mizuno, Stefano Mossa, Jean-Louis Barrat
Glasses exhibit spatially inhomogeneous elastic properties, which can be investigated by measuring their elastic moduli at a local scale. Various methods to evaluate the local elas…
Non-conservative forces and effective temperatures in active polymers
Davide Loi, Stefano Mossa, Leticia F. Cugliandolo
We follow the dynamics of an ensemble of interacting self-propelled semi-flexible polymers in contact with a thermal bath. We characterize structure and dynamics of the passive sys…
Exact curvilinear diffusion coefficients in the repton model
Arnaud Buhot
The Rubinstein-Duke or repton model is one of the simplest lattice model of reptation for the diffusion of a polymer in a gel or a melt. Recently, a slightly modified model with ha…
Brush Effects on DNA Chips: Thermodynamics, Kinetics and Design Guidlines
A. Halperin, A. Buhot, E. B. Zhulina
In biology experiments, oligonucleotide microarrays are contacted with a solution of long nucleic acid (NA) targets. The hybridized probes thus carry long tails. When the surface d…
Cluster algorithm for non-additive hard-core mixtures
Arnaud Buhot
In this paper, we present a cluster algorithm for the numerical simulations of non-additive hard-core mixtures. This algorithm allows one to simulate and equilibrate systems with a…
The Effects of Stacking on the Configurations and Elasticity of Single Stranded Nucleic Acids
A. Buhot, A. Halperin
Stacking interactions in single stranded nucleic acids give rise to configurations of an annealed rod-coil multiblock copolymer. Theoretical analysis identifies the resulting signa…
Kovacs effect and fluctuation-dissipation relations in 1D kinetically constrained models
Arnaud Buhot
Strong and fragile glass relaxation behaviours are obtained simply changing the constraints of the kinetically constrained Ising chain from symmetric to purely asymmetric. We study…
Analytical estimate of effective charges at saturation in Poisson-Boltzmann cell models
Emmanuel Trizac, Miguel Aubouy, Lyderic Bocquet
We propose a simple approximation scheme to compute the effective charge of highly charged colloids (spherical or cylindrical with infinite length). Within non-linear Poisson-Boltz…
Concentration Dependence of the Flory Chi Parameter within Two-State Models
V. A. Baulin, A. Halperin
The Flory chi parameter is typically assumed to depend only on the temperature, T. Experimental results often require the replacement of this chi(T) by chieff, that depends also on…
A simple approach for charge renormalization of highly charged macro-ions
Emmanuel Trizac, Lyderic Bocquet, Miguel Aubouy
We revisit the popular notion of effective or renormalized charge, which is a concept of central importance in the field of highly charged colloidal or polyelectrolyte solutions. W…
On the Extension Behavior of Helicogenic Polypeptides
Arnaud Buhot, Avraham Halperin
The force laws governing the extension behavior of homopolypeptides are obtained from a phenomenological free energy capable of describing the helix-coil transition. Just above the…
Inwardly curved polymer brushes : Concave is not like Convex
Manoel Manghi, Miguel Aubouy, Cyprien Gay +1
Inwardly curved polymer brushes are present in cylindrical and spherical micelles or in membranes tubes and vesicles decorated with anchored polymers, and influence their stability…
On the Helix-Coil transition in grafted chains
A. Buhot, A. Halperin
The helix-coil transition is modified by grafting to a surface. This modification is studied for short peptides capable of forming -helices. Three factors are involved: (i) the…
The Extension of Rod-Coil Multiblock Copolymers and the Effect of the Helix-Coil Transition
A. Buhot, A. Halperin
The extension elasticity of rod-coil mutliblock copolymers is analyzed for two experimentally accessible situations. In the quenched case, when the architecture is fixed by the syn…
Early Stages of Homopolymer Collapse
A. Halperin, Paul M. Goldbart
Interest in the protein folding problem has motivated a wide range of theoretical and experimental studies of the kinetics of the collapse of flexible homopolymers. In this Paper a…
