Collective effects of torsion in FtsZ filaments.

Physical review. E

González de Prado Salas P, Tarazona P.
PMID: 27176329
Phys Rev E. 2016 Apr;93:042407. doi: 10.1103/PhysRevE.93.042407. Epub 2016 Apr 11.

Recent evidence points to the presence of torsion in FtsZ bonds. In addition, experiments with FtsZ mutants on surfaces resulted in new aggregates that cannot be explained by older models for FtsZ dynamics. We use an interaction model for...

Layering at free liquid surfaces.

Physical review letters

Chacón E, Reinaldo-Falagán M, Velasco E, Tarazona P.
PMID: 11690216
Phys Rev Lett. 2001 Oct 15;87(16):166101. doi: 10.1103/PhysRevLett.87.166101. Epub 2001 Sep 26.

We show that simple liquids, with appropriate choices of the isotropic pair interaction, may exhibit surface layering above the melting temperature. Results for the liquid surface have been obtained by Monte Carlo simulations in slab geometry. Surface layering appears...

Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Nov;62(5):7147-54. doi: 10.1103/physreve.62.7147.

Dense phases of micellar aggregates have strong molecular correlation at two different levels: that of the molecules forming a micelle and that between micelles, leading to a possible phase transition from a micellar fluid to a micellar crystal. The...

Lattice-gas model driven by Hubbard electrons.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Reinaldo-Falagán M, Tarazona P, Chacón E, Hernandez JP.

Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Sep;60(3):2626-35. doi: 10.1103/physreve.60.2626.

Self-consistent Monte Carlo simulations are undertaken for a lattice-gas model which is driven by the free energy of electrons described by a Hubbard model with electronic hopping restricted to ions at nearest-neighbor sites. Our previous work, an independent-electron tight-binding...

Environ Pollut. 1996;93(2):135-9. doi: 10.1016/0269-7491(96)00034-6.

Four river water samples (R) and three sewage samples (S) were collected at different points in the Jarama River, Spain. Organic concentrates were tested on the RTG-2 in vitro cytotoxicity test and analyzed by HPLC and GC/MS. The cytotoxicity...

Critical analysis of the density functional theory prediction of enhanced capillary waves.

Physical review letters

Tarazona P, Checa R, Chacón E.
PMID: 18233085
Phys Rev Lett. 2007 Nov 09;99(19):196101. doi: 10.1103/PhysRevLett.99.196101. Epub 2007 Nov 05.

We present a critical analysis of the density functional description for capillary wave fluctuations on free liquid surfaces. The proposal made by Mecke and Dietrich, [Phys. Rev. E 59, 6766 (1999)10.1103/PhysRevE.59.6766], to obtain the effective wave vector dependent surface...

Capillary wave fluctuations smooth out the structure of fluid interfaces, making difficult the detailed analysis of the interfacial structure. Most computer simulation investigations performed to date have focused on the computation of average density profiles, ignoring the characterization of...

We present a brief review of the advances made in the characterization of liquid surfaces over the last decade. We focus particularly on the links between the capillary wave theory, the density functional formalism and the direct evaluation of...

Chemistry. 2013 Apr 26;19(18):5644-53. doi: 10.1002/chem.201203458. Epub 2013 Mar 04.

A series of optically active helical polyphosphazene block copolymers of general formula R-[N=P(O2C20H12)]n-b-[N=PMePh]m (R-7 a-c) was synthesized and characterized. The polymers were prepared by sequential living cationic polycondensation of N-silylphosphoranimines using the mono-end-capped initiator [Ph3 P=N=PCl3][PCl6] (5) and exhibit...
