Empty liquid phase of colloidal ellipsoids: the role of shape and interaction anisotropy.

The Journal of chemical physics

Varga S, Meneses-Júarez E, Odriozola G.
PMID: 24712814
J Chem Phys. 2014 Apr 07;140(13):134905. doi: 10.1063/1.4869938.

We study the effect of anisotropic excluded volume and attractive interactions on the vapor-liquid phase transition of colloidal ellipsoids. In our model, the hard ellipsoid is embedded into an ellipsoidal well, where both the shape of the hard ellipsoid...

Entropy Driven Self-Assembly in Charged Lock-Key Particles.

In this work we study the lock-key model successfully used in supramolecular chemistry and particles self-assembly and gain further insight into the infinite diluted limit of the lock and key, depletant mediated, effective attraction. We discuss the depletant forces...

Stimuli-responsive reversible coloration-change materials represent a highly demanded type of smart systems useful for a wide variety of applications, with a significant growing interest in multicolor abilities. In particular, electrochromic materials have received a great deal of attention due...

Effect of orientational restriction on monolayers of hard ellipsoids.

Physical chemistry chemical physics : PCCP

Varga S, Martínez-Ratón Y, Velasco E, Bautista-Carbajal G, Odriozola G.
PMID: 26796794
Phys Chem Chem Phys. 2016 Feb 14;18(6):4547-56. doi: 10.1039/c5cp05702g.

The effect of out-of-plane orientational freedom on the orientational ordering properties of a monolayer of hard ellipsoids is studied using the Parsons-Lee scaling approach and replica exchange Monte Carlo computer simulation. Prolate and oblate ellipsoids exhibit very different ordering...

Coupled aggregation and sedimentation processes: the sticking probability effect.

Physical review. E, Statistical, nonlinear, and soft matter physics

Odriozola G, Leone R, Schmitt A, Moncho-Jordá A, Hidalgo-Alvarez R.
PMID: 12689061
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Mar;67(3):031401. doi: 10.1103/PhysRevE.67.031401. Epub 2003 Mar 18.

The influence of the sticking probability P and the drift velocity on kinetics and structure formation arising in coupled aggregation and sedimentation processes was studied by means of simulations. For this purpose, a large prism with no periodical conditions...

Brownian dynamics simulations of Laponite colloid suspensions.

Physical review. E, Statistical, nonlinear, and soft matter physics

Odriozola G, Romero-Bastida M, Guevara-Rodríguez Fde J.

Colloidal suspensions of Laponite clay platelets are studied by means of Brownian dynamics simulations. The platelets carry discrete charged sites which interact via a Yukawa potential. As in the paper by S. Kutter et al. [J. Chem. Phys. 112,...

Linking phase behavior and reversible colloidal aggregation at low concentrations: simulations and stochastic mean field theory.

The journal of physical chemistry. B

Puertas AM, Odriozola G.
PMID: 17461568
J Phys Chem B. 2007 May 24;111(20):5564-72. doi: 10.1021/jp068698b. Epub 2007 Apr 27.

We have studied the link between the kinetics of clustering and the phase behavior of dilute colloids with short range attractions of moderate strength. This was done by means of computer simulations and a theoretical kinetic model originally developed...

Conjugate addition of nitroalkanes to an acrylate equivalent. Stereocontrol at C-alpha of the nitro group through double catalytic activation.

Organic letters

García JM, Maestro MA, Oiarbide M, Odriozola JM, Razkin J, Palomo C.

An unprecedented highly selective direct conjugate addition of prochiral nitroalkanes (R not equal H) to acrylate equivalents is described. The method employs a unique Lewis acid/Brønsted base/MS ternary catalytic system and affords products with dr up to 97/3. With...

Na-montmorillonite hydrates under ethane rich reservoirs: NPzzT and muPzzT simulations.

The Journal of chemical physics

Na-montmorillonite hydrates in presence of ethane molecules are studied by means of hybrid Monte Carlo simulations in the NP(zz)T and muP(zz)T ensembles. The NP(zz)T ensemble allows us to study the interlaminar distance as a function of water and ethane...

Further details on the phase diagram of hard ellipsoids of revolution.
