Using an Ionic Liquid to Reduce the Electrical Percolation Threshold in Biobased Thermoplastic Polyurethane/Graphene Nanocomposites
(MDPI, 2019-03)
Biobased thermoplastic polyurethane (bTPU)/unmodified graphene (GR) nanocomposites (NCs) were obtained by melt-mixing in a lab-scaled conventional twin-screw extruder. Alternatively, GR was also modified with an ionic ...
Modelling of polymer-carbon nanotube heterojunctions for photovoltaic applications
(2017-01-31)
Semiconducting single-walled carbon nanotubes (s-SWNT) are promising materialsfor efficient organic photovoltaics (OPVs). Unfortunately, the implementation of s-SWNTs has so far not lead to the expected increase in power ...
Single-shot temporal characterization of XUV pulses with duration from ~10 fs to ~350 fs at FLASH
(IOP, 2020-09-28)
Ultra-short extreme ultraviolet pulses from the free-electron laser FLASH are characterized using terahertz-field driven streaking. Measurements at different ultra-short extreme ultraviolet wavelengths and pulse durations ...
Contribution to the theoretical description of N2 dynamics on W(100).
(2018-12-10)
Elementary processes at the gas-solid interface are of great interest in many scientific domains. This molecule-surface reactions play a key role in the study of: heterogeneous catalysis processes, plasma-wal interactions ...
Dynamics of diatomic molecules on metal surfaces: O2/Ag(110) and CO/Ru(0001)
(2017-01-25)
This thesis concerns with theoretical modelling from first principles of dynamics of two gas-surface systems (oxygen on silver and carbon monoxide on ruthenium) that are relevant to the heterogeneous catalysis. An accurate ...
Two-color XUV plus NIR femtosecond photoionization of neon in the near-threshold region
(IOP Publishing, 2019-06-28)
Results of angle-resolved electron spectroscopy of near-threshold photoionization of Ne atoms by combined femtosecond extreme ultraviolet and near infrared fields are presented. The dressed-electron spectra show an energetic ...
Understanding of plasticizer effect on the temperature dependence of mechanical and dielectric relaxation function of polymers of interest for tire formulation.
(2019-06-04)
Las propiedades dinámicas de los elastómeros en régimen lineal son una de las líneas de investigación centrales de Michelin. La comprensión del efecto del plastificante en la dependencia en temperatura de la relajación ...
The structure and the dynamics of poly(vinyl methyl ether) PVME and in PVME concentrated water solution : a study by neutron scattering and fully atomistic molecular dynamics simulations
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2011-05-09)
El agua juega un papel fundamental en los procesos biológicos. Una gran parte de ella se encuentra cerca de biomoléculas fundamentales afectando a sus propias funcionalidades. Por ello el estudio del agua en sistemas ...
Computational investigations of single-chain nanoparticles: novel synthesis routes, complex flow behavior and reversible gel formation.
(2020-01-17)
Las llamadas nanopartículas unicadena ("single-chain nanoparticles", SCNPs) se obtienen mediante enlazamiento puramente intramolecular de precursores poliméricos. Hay un interés creciente en estos sistemas debido a sus ...
Insight into the Structure and Dynamics of Polymers by Neutron Scattering Combined with Atomistic Molecular Dynamics Simulations
(MDPI, 2020-12-21)
Combining neutron scattering and fully atomistic molecular dynamics simulations allows unraveling structural and dynamical features of polymer melts at different length scales, mainly in the intermolecular and monomeric ...
