Acoustic plasmons in extrinsic free-standing graphene
(IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...
Non-adiabatic processes in the radiation damage of materials from first principles
(2018-03-23)
El paso rápido de iones a través de un sistema de materia condensadaconstituye un problema cuánntico de muchos cuerpos dependientedel tiempo. La complejidad del problema hace que sea extremadamentedifícil encontrar una ...
Advances in Single-Chain Nanoparticles for Catalysis Applications
(MDPI, 2017-10-21)
Enzymes are the most efficient catalysts known for working in an aqueous environment near room temperature. The folding of individual polymer chains to functional single-chain nanoparticles (SCNPs) offers many opportunities ...
Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation
(Hindawi Publishing, 2015)
Single-chain technology (SCT) allows the transformation of individual polymer chains to folded/collapsed unimolecular soft nanoparticles. In this work we contribute to the enlargement of the SCT toolbox by demonstrating ...
Electronic and spintronic devices using two-dimensional materials
(2017-05-30)
Ever since in 2004 atomically-thin two-dimensional van der Waals materials became available to the scientific community, at the reach of manual microexfoliation techniques, their implementation in novel device structures ...
Chain dynamics in crosslinked filled and unfilled polymer blends of different miscibility
(2018-03-16)
En ésta tesis se han analizado compuestos vulcanizados de caucho natural (NR), caucho de butadieno (BR), caucho de estireno-butadieno (SBR) con diferentes microestructuras, y caucho de estireno-butadieno con funcionalización ...
Motions of Water and Solutes-Slaving Versus Plasticization Phenomena
(American Institute of Physics, 2019-03-28)
It is well-accepted that hydration water is crucial for the structure, dynamics, and function of proteins. However, the exact role of water for the motions and functions of proteins is still debated. Experiments have shown ...
Morphology and dynamics of ice crystals and the effect of proteins
(2017-07-17)
La tesis "Morfología y dinámica de los cristales de hielo y su efecto en las proteínas" se basa en una amplia gama de temas que abarcan el fundamento de la estructura del hielo (tanto su superficie como su morfología), la ...
Dynamics of biological and non-biological aqueous solutions-Evidence of coupling between the motions of water and solutes
(2017-06-21)
Las proteínas son sistemas dinámicos que interactúan fuertemente con su entorno, de hecho, el propio disolvente es el que potencia los movimientos, aportando flexibilidad a la estructura de la molécula para que esta pueda ...
Study of geometrical frustration and thermal activation in arrays of magnetic nanostructures
(2018-06-18)
La tesis trata de nanoescructuras magnéticas, definidas por la disminución de sus tres dimensiones hasta cientos de nanómetros y formadas por materiales magnéticos. La introducción de interacciones en un conjunto de ...
