Optical properties and sensing in plexcitonic nanocavities: from simple molecular linkers to molecular aggregate layers.

Nanotechnology

Pérez-González O, Zabala N, Aizpurua J.
PMID: 24346140
Nanotechnology. 2014 Jan 24;25(3):035201. doi: 10.1088/0957-4484/25/3/035201. Epub 2013 Dec 17.

We present a theoretical study of a metal-molecular aggregate hybrid system consisting of a strongly coupled dimer connected by molecules characterized by an excitonic transition. The plasmonic resonances of the metallic dimer interact with the molecular excitations giving rise...

Quality Characteristics and Shelf-Life of Ultra-High Pressure Homogenized (UHPH) Almond Beverage.

Ferragut V, Valencia-Flores DC, Pérez-González M, Gallardo J, Hernández-Herrero M.
PMID: 28231196
Foods. 2015 May 20;4(2):159-172. doi: 10.3390/foods4020159.

The effects of ultra-high-pressure homogenization (UHPH) at 200 MPa, in combination with different inlet temperatures (55 or 75 °C) during storage at 4 °C were studied and compared with pasteurized (90 °C, 90 s) almond beverage. Microbiological analysis of...

On the chemical behavior of C60 hosting H2O and other isoelectronic neutral molecules.

Journal of molecular modeling

Galano A, Pérez-González A, del Olmo L, Francisco-Marquez M, León-Carmona JR.
PMID: 25119317
J Mol Model. 2014 Aug;20(8):2412. doi: 10.1007/s00894-014-2412-4. Epub 2014 Aug 14.

The density functional theory (DFT) was used to investigate the chemical behavior of C60 hosting neutral guest molecules (NGM). The deformed atoms in molecules (DAM) allowed identifying the regions of electron density depletion and accumulation. The studied NGM are...

beta-Hydroxysulfoxides as chiral cyclic ketone equivalents: enantioselective synthesis of polysubstituted cyclohexanones, cyclohexenones and cyclohexenediones.

Chemical communications (Cambridge, England)

Carreño MC, Pérez-González M, Ribagorda M, Somoza A, Urbano A.
PMID: 12536812
Chem Commun (Camb). 2002 Dec 21;(24):3052-3. doi: 10.1039/b209121f.

The beta-hydroxysulfoxide moiety, after oxidation to sulfone, acts as a masked carbonyl group in a cyclic system, opening an easy access to differently substituted enantiomerically pure cyclic ketones by means of aluminium-mediated conjugate additions, stereoselective reductions and elimination by...

Concept formation based on the relations among values of multi-component figures.

Behavioural processes

Pérez-González LA.
PMID: 11566232
Behav Processes. 2001 Oct 01;56(1):1-14. doi: 10.1016/s0376-6357(01)00169-3.

A complex discrimination procedure was used to test class formation with multi-component figures in college students. First, selections of a red-+45 degrees -oriented rectangle (A1B1) instead of a red -45 degrees -oriented rectangle (A1B2) and of a green -45...

Optical transport and sensing in plexcitonic nanocavities.

Optics express

Pérez-González O, Aizpurua J, Zabala N.
PMID: 23842371
Opt Express. 2013 Jul 01;21(13):15847-58. doi: 10.1364/OE.21.015847.

We present a theoretical study of the optical properties of a strongly coupled metallic dimer when an ensemble of molecules is placed in the inter-particle cavity. The linking molecules are characterized by an excitonic transition which couples to the...

Fluorescent property of 3-hydroxymethyl imidazo[1,2-a]pyridine and pyrimidine derivatives.

Chemistry Central journal

Velázquez-Olvera S, Salgado-Zamora H, Velázquez-Ponce M, Campos-Aldrete E, Reyes-Arellano A, Pérez-González C.
PMID: 22871219
Chem Cent J. 2012 Aug 07;6(1):83. doi: 10.1186/1752-153X-6-83.

BACKGROUND: Imidazo[1,2-a]pyridines and pyrimidines are important organic fluorophores which have been investigated as biomarkers and photochemical sensors. The effect on the luminescent property by substituents in the heterocycle and phenyl rings, have been studied as well. In this investigation,...

Simulation of 1D Topological Phases in Driven Quantum Dot Arrays.

Physical review letters

Pérez-González B, Bello M, Platero G, Gómez-León Á.
PMID: 31633970
Phys Rev Lett. 2019 Sep 20;123(12):126401. doi: 10.1103/PhysRevLett.123.126401.

We propose a driving protocol which allows us to use quantum dot arrays as quantum simulators for 1D topological phases. We show that by driving the system out of equilibrium, one can imprint bond order in the lattice (producing...

Active wetting of epithelial tissues.

Nature physics

Pérez-González C, Alert R, Blanch-Mercader C, Gómez-González M, Kolodziej T, Bazellieres E, Casademunt J, Trepat X.
PMID: 31537984
Nat Phys. 2019 Jan;15(1):79-88. doi: 10.1038/s41567-018-0279-5. Epub 2018 Sep 24.

Development, regeneration and cancer involve drastic transitions in tissue morphology. In analogy with the behavior of inert fluids, some of these transitions have been interpreted as wetting transitions. The validity and scope of this analogy are unclear, however, because...

Fatigue Analysis of NiTi Rotary Endodontic Files through Finite Element Simulation: Effect of Root Canal Geometry on Fatigue Life.
