Ionic Liquid-Cured Epoxy/PCL Blends with Improved Toughness and Adhesive Properties
(MDPI, 2022)
In this work, ionic liquid (IL)-cured epoxy resins were modified by adding poly(ε-caprolactone) (PCL). Three different ILs were used in order to study how (a) the chemical structure of the ILs and (b) the PCL content affect ...
Spin excitations of individual magnetic dopants in an ionic thin film
(IOP, 2022-10)
Individual magnetic transition metal dopants in a solid host usually exhibit relatively small spin excitation energies of a few meV. Using scanning tunneling microscopy and inelastic electron tunneling spectroscopy (IETS) ...
Empleo de líquidos iónicos para la mejora de la sostenibilidad y propiedades de sistemas basados en resinas epoxi y en PLA
(2022-10-17)
El objetivo principal de esta Tesis doctoral es la mejora de la sostenibilidad y propiedades tanto de sistemas termoestables como termoplásticos mediante el empleo de líquidos iónicos. En literatura se reporta la capacidad ...
Simulating Terahertz Field-Induced Ferroelectricity in Quantum Paraelectric SrTiO3
(American Physical Society, 2022-10)
Recent experiments have demonstrated that light can induce a transition from the quantum paraelectric to the ferroelectric phase of SrTiO3. Here, we investigate this terahertz field-induced ferroelectric phase transition ...
H atom scattering from W(110): A benchmark for molecular dynamics with electronic friction.
(Royal Society of Chemistry, 2022-08)
Molecular dynamics with electronic friction (MDEF) at the level of the local density friction approximation (LDFA) has been applied to describe electronically non-adiabatic energy transfer accompanying H atom collisions ...
Sustainable oxygen evolution electrocatalysis in aqueous 1 M H2SO4 with earth abundant nanostructured Co3O4
(Nature, 2022)
Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) able to work in acidic working conditions are elusive. While many first-row transition metal oxides are competitive in alkaline media, most of them ...
Temperature modulated DSC for composition analysis of recycled polyolefin blends
(Elsevier, 2022-09)
Post-consumer plastic waste contains blends of numerous types of polyethylene (PE) and isotactic polypropylene (i-PP), whose recycling is challenging due to the complexity of this waste stream. A comprehensive knowledge ...
Supernucleation Dominates Lignin/Poly(ethylene oxide) Crystallization Kinetics
(American Chemical Society, 2022)
The effect of lignin nanoparticles (LNPs) on the crystallization kinetics of poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter of 85 nm ...
Disentangling the Calorimetric Glass-Transition Trace in Polymer/ Oligomer Mixtures from the Modeling of Dielectric Relaxation and the Input of Small-Angle Neutron Scattering
(American Chemical Society, 2022-08)
We have disentangled the contributions to the glass transition as observed by differential scanning calorimetry (DSC) on simplified systems of industrial interest consisting of blends of styrene-butadiene rubber (SBR) and ...
Effect of Chain Stereoconfiguration on Poly(3-hydroxybutyrate) Crystallization Kinetics
(American Chemical Society, 2022-08)
Poly(3-hydroxybutyrate) (PHB) is naturally accumulated by bacteria but can also be synthesized chemically. Its processability is limited, as it tends to degrade at temperatures above its melting temperature; hence, ...
