How to switch from a poor PEDOT:X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT:metallacarborane

PlumX: How to switch from a poor PEDOT:X oxygen evolution reaction (OER) to a good one. A study on dual redox reversible PEDOT:metallacarborane
Over the years, extensive research has been carried out to optimize the oxygen evolution reaction (OER) by adopting different techniques as well as catalysts. Conducting organic polymers such as PEDOT have been employed to study the reaction but have failed to lower the over-potential for the reaction. Here we show electrochemically made, intimately blended, dual redox reversible materials incorporating PEDOT and metallacarboranes. The metallacarboranes act as doping agents but with tunable E1/2 potentials. The tunability of E1/2 allows the overlapping of the two redox potentials which subsequently leads to their synergy. The physico-chemical properties of the metallacarboranes fade and become integrated with PEDOT to form a dual redox reversible system. Therefore, the properties of the dopant are modified by the polymer.

Welcome to the ICMAB Annual Report 2021

2021 has been a year characterized by the "back-to-normal" life after the pandemic. 

The ICMAB has, step by step, returned to normality, but continuing with online and hybrid events and meetings, and with limitted capacity in the labs and offices for most of the year, and strict conditions to ensure the safety and health of all the ICMABers. 

However, our researchers and all our staff have worked hard to continue making this center one of the top centers in materials science research of the world.

Kinetic Control of Ultrafast Transient Liquid Assisted Growth of Solution-Derived YBa2Cu3O7-x Superconducting Films

PlumX: Kinetic Control of Ultrafast Transient Liquid Assisted Growth of Solution-Derived YBa2Cu3O7-x Superconducting Films
Transient liquid assisted growth (TLAG) is an ultrafast non-equilibrium growth process mainly governed by kinetic parameters, which are only accessible through fast in situ characterizations. In situ synchrotron X-ray diffraction (XRD) analysis and in situ electrical resistivity measurements are used to derive kinetic diagrams of YBa2Cu3O7−x (YBCO) superconducting films prepared via TLAG and to reveal the unique peculiarities of the process. In particular, diagrams for the phase evolution and the YBCO growth rates have been built for the two TLAG routes. It is shown that TLAG transient liquids can be obtained upon the melting of two barium cuprate phases (and not just one), differentiated by their copper oxidation state.

Phonon Transport in GaAs and InAs Twinning Superlattices

PlumX: Phonon Transport in GaAs and InAs Twinning Superlattices
Crystal phase engineering gives access to new types of periodic nanostructures, such as the so-called twinning superlattices, where the motif of the superlattice is determined by a periodic rotation of the crystal. Here, by means of atomistic nonequilibrium molecular dynamics calculations, we study to what extent these periodic systems can be used to alter phonon transport in a controlled way, similar to what has been predicted and observed in conventional superlattices based on heterointerfaces.

Control of up-to-down/down-to-up light-induced ferroelectric polarization reversal

Título : Control of up-to-down/down-to-up light-induced ferroelectric polarization reversal
Autores: Huan Tan, Gustavo Castro, Jike Lyu, Pablo Loza-Alvarez, Florencio Sánchez, Josep Fontcuberta and Ignasi Fina
Citation and DOI: Mater. Horiz., 2022,9, 2345-2352
DOI: https://doi.org/10.1039/D2MH00644H
PlumX: Control of up-to-down/down-to-up light-induced ferroelectric polarization reversal
Light control of ferroelectric polarization is of interest for the exploitation of ferroelectric thin films in ultrafast data storage and logic functionalities. The rapidly oscillating electric field of light absorbed in a ferroelectric layer can suppress its polarization but cannot selectively reverse its direction. Here we take advantage of the built-in asymmetry at ferroelectric/electrode interfaces to break the up/down symmetry in uniaxial ferroelectrics to promote polarization reversal under illumination. It is shown that appropriate ferroelectric/metal structures allow the direction of the imprint electric field to be selected, which is instrumental for polarization reversal. This ability is further exploited by demonstrating the optical control of the resistance states in a ferroelectric capacitor.

PlumX: Surface Lattice Plasmon Resonances by Direct In Situ Substrate Growth of Gold Nanoparticles in Ordered Arrays
Precise arrangements of plasmonic nanoparticles on substrates are important for designing optoelectronics, sensors and metamaterials with rational electronic, optical and magnetic properties. Bottom-up synthesis offers unmatched control over morphology and optical response of individual plasmonic building blocks. Usually, the incorporation of nanoparticles made by bottom-up wet chemistry starts from batch synthesis of colloids, which requires time-consuming and hard-to-scale steps like ligand exchange and self-assembly.

PlumX: The Third Dimension of Ferroelectric Domain Walls
Ferroelectric domain walls are quasi-2D systems that show great promise for the development of nonvolatile memory, memristor technology, and electronic components with ultrasmall feature size. Electric fields, for example, can change the domain wall orientation relative to the spontaneous polarization and switch between resistive and conductive states, controlling the electrical current.

PlumX: Molecular Dynamics Simulations of Adsorption of SARS-CoV-2 Spike Protein on Polystyrene Surface
A prominent feature of coronaviruses is the presence of a large glycoprotein spike (S) protruding from the viral particle. The specific interactions of a material with S determine key aspects such as its possible role for indirect transmission or its suitability as a virucidal material. Here, we consider all-atom molecular dynamics simulations of the interaction between a polymer surface (polystyrene) and S in its up and down conformations.
