Epitaxial orthorhombic Hf0.5Zr0.5O2 (HZO) films on La0.67Sr0.33MnO3 (LSMO) electrodes show robust ferroelectricity, with high polarization, endurance and retention. However, no similar results have been achieved using other perovskite electrodes so far. Here, LSMO and other perovskite electrodes are compared.

Lactose intolerance is a pathology caused by lactase enzyme deficiency, usually produced in the intestinal cells provoking symptoms as abdominal pain, bloating, diarrhea, gas and nausea. Gaxilose, 4-O-β-D galactopyranosyl-d-xylose, is used as a diagnostic drug for a non-invasive method for hypolactasia diagnosis.

How has the lockdown, restrictions, and the work from home lifestyle affected our research?

Monday, 16 March 2020 was not like any other Monday.

News came from China and Italy, about a fast spreading virus that required strict lockdowns to avoid its spread. It was clear than sooner, rather than later, actions would have to be taken everywhere else.

Facile Chemical Route to Prepare Water Soluble Epitaxial Sr3Al2O6 Sacrificial Layers for Free‐Standing Oxides

Título : Facile Chemical Route to Prepare Water Soluble Epitaxial Sr3Al2O6 Sacrificial Layers for Free‐Standing Oxides
Autores: Pol Salles, Ivan Caño, Roger Guzman, Camilla Dore, Agustín Mihi, Wu Zhou, Mariona Coll
Citation: Adv. Mater. Interfaces 2021, 2001643. 
DOI: https://doi.org/10.1002/admi.202001643
PlumX: Facile Chemical Route to Prepare Water Soluble Epitaxial Sr3Al2O6 Sacrificial Layers for Free‐Standing Oxides
The growth of epitaxial complex oxides has been essentially limited to specific substrates that can induce epitaxial growth and stand high temperature thermal treatments. These restrictions hinder the opportunity to manipulate and integrate such materials into new artificial heterostructures including the use of polymeric and silicon substrates and study emergent phenomena for novel applications.

PlumX: Disentangling Electron–Phonon Coupling and Thermal Expansion Effects in the Band Gap Renormalization of Perovskite Nanocrystals
The complex electron–phonon interaction occurring in bulk lead halide perovskites gives rise to anomalous temperature dependences, like the widening of the electronic band gap as temperature increases. However, possible confinement effects on the electron–phonon coupling in the nanocrystalline version of these materials remain unexplored. Herein, we study the temperature (ranging from 80 K to ambient) and hydrostatic pressure (from atmospheric to 0.6 GPa) dependence of the photoluminescence of ligand-free methylammonium lead triiodide nanocrystals with controlled sizes embedded in a porous silica matrix.

Tweed texture revealed in vanadium dioxide in metal-insulator transitions

Written by Anna on .

The study of metal-insulator transitions in VO2 through atomic scale imaging has allowed to uncover a periodical tweed structure: a weaving of vanadium dimers acting like the threads of an actual tweed at the atomic level. This research, led by ICMAB researcher Felip Sandiumenge and ICN2 and ICREA researcher Gustau Catalan, and published in Advanced Materials, provides relevant information for the understanding of transitional states in specific classes of materials.

ICMAB researchers from the LMI group have collaborated in a study to design minimalist biostructures that imitate natural enzymes, capable of carrying out two differentiated and reversibly regulated activities thanks to a unique combination of structural and functional properties. The strategy used opens the door to the creation of “intelligent” nanomaterials with tailor-made combinations of catalytic functions.

Non-volatile optical switch of resistance in photoferroelectric tunnel junctions

PlumX: Non-volatile optical switch of resistance in photoferroelectric tunnel junctions
In the quest for energy efficient and fast memory elements, optically controlled ferroelectric memories are promising candidates. Here, we show that, by taking advantage of the imprint electric field existing in the nanometric BaTiO3 films and their photovoltaic response at visible light, the polarization of suitably written domains can be reversed under illumination. We exploit this effect to trigger and measure the associate change of resistance in tunnel devices.

Written by Artur on .

The CSIC White Paper presents the interdisciplinary approaches that the CSIC Research Centers are applying in order to face several of the scientific and social challenges of the next 10 years.

CSIC introduced the White Paper in a digital event livestreamed and now archived on YouTube, analyzing several topics across its three areas of work: Life, Matter, and Society. These documents cover the whole spectrum of research, from basic investigation to potential applications of the results achieved, in order to create helpful strategies and organization models to apply when facing the main challenges we will encounter in the coming years.
