Photovoltaic-driven dual optical writing and non-destructive voltage-less reading of polarization in ferroelectric Hf0.5Zr0.5O2 for energy efficient memory devices

Ferroelectric doped hafnium oxide constitutes, at present, an intensively investigated candidate material to develop outperforming non-volatile memory devices. We report reading and writing of the ferroelectric polarization with light in Hf0.5Zr0.5O2/Nb:SrTiO3 structures, where light is absorbed at the interface between the two materials, thereby enabling both processes. Reading of ferroelectric polarization is accomplished through the induced short-circuit photocurrents, which is a pathway towards voltage-less-non-destructive reading.

COVER. The cover displays [Gd(MeCOO)(PhCOO)2], a new Gd-based 2D MOF synthesized and characterized by E. Bartolomé (ICMAB-CSIC), C. Sañudo (UB) et al. The material shows magnetocaloric effect both in bulk and chemisorbed on a Silicon substrate, opening up the possibilities for on-surface cooling devices.

A new molecular Gd-based 2D metal-organic-framework opens new frontiers to on-surface magnetic cooling of technological devices

The new edition of the Journal of Materials Chemistry A portrays in its cover a novel on-surface deposited Gd 2D metal-organic framework (MOF), investigated by an international research team led by Carolina Sañudo (UB) and Elena Bartolomé (ICMAB-CSIC). The team comprises people from the Institute of Theoretical and Computational Chemistry of the UB (IQTCUB), the Institute of Nanoscience and Materials of Aragon (INMA/CSIC/UNIZAR), the National High Magnetic Field Laboratory (United States) and the University of Oxford (United Kingdom).

Tailoring the Electron-Deficient Central Core on Fused-Ring Nonfullerene Acceptors: Deciphering the Relationships Between Structure, Property, and Photovoltaic Performance

In the field of organic solar cells, organic semiconductors with Y6-based chemical structure and their corresponding quinoxaline-based assemblies are settled down as promising materials in the field of OSCs. However, the chemical structure of Y6 derivatives does not allow an expansion in the electron-withdrawing central core, in contrast to their quinoxaline-based analogues.

Redox-Active Au Nanoparticles Self-Assembled at Liquid–Liquid Interface via C–Au Functionalization for Dye Degradation Electrocatalysis

This work presents the synthesis of poly(vinylpyrrolidone)-stabilized gold nanoparticles (Au NPs) and their subsequent functionalization with molecules bearing terminal alkynes. The ligand exchange occurs at the liquid–liquid interface (LLI), resulting in the formation of Au NPs stabilized through the covalent C–Au functionalization.

Caenorhabditis elegans endorse bacterial nanocellulose fibers as functional dietary Fiber reducing lipid markers

Bacterial nanocellulose (BNC) is a promising dietary fiber with potential as a functional food additive. We evaluated BNC fibers (BNCf) in the Caenorhabditis elegans model to obtain insight into the BNCf's biointeraction with its gastrointestinal tract while reducing the variables of higher complex animals.

Welcome Anna Drou Roget at ICMAB!

  • Anna Drou Roget
Hi to everyone! I'm Anna and I am joining the Communication and Outreach team at ICMAB. My background is in Physics (degree at UAB). Then I moved to an MSc. in Physics and Science Communication and Society at Leiden University. From then on I have worked in communication in research centers and in outreach and popularisation activities in different formats. I have a strong passion for bridging the gap between science and society by exploring multiple ways of communication. I am thrilled to be at ICMAB, to learn more about the research done here and to help with the communication and outreach in the centre. Looking forward to meeting you all!

Natural Optical Activity from Density-Functional Perturbation Theory

We present an accurate and computationally efficient first-principles methodology to calculate natural optical activity. Our approach is based on the long-wave density-functional perturbation theory and includes self-consistent field terms naturally in the formalism, which are found to be of crucial importance.

New animal model created to study Parkinson's disease before neurodegeneration appears

A research team in which ICMAB-CSIC has participated has managed to generate and validate a new animal model.  This model enables the examination of the initial phases of Parkinson's disease, occurring prior to the onset of motor symptoms, and the exploration of molecular processes preceding neuronal degeneration. The new model, based on the Caenorhabditis elegans worm, emerges as an essential tool in creating future therapies aimed at stopping the characteristic loss of neuronal structure and function seen in the disease.

In-Plane Flexoelectricity in Two-Dimensional D3d Crystals

We predict a large in-plane polarization response to bending in a broad class of trigonal two-dimensional crystals. We define and compute the relevant flexoelectric coefficients from first principles as linear-response properties of the undistorted layer by using the primitive crystal cell.

Absence of 3a0 charge density wave order in the infinite-layer nickelate NdNiO2

A hallmark of many unconventional superconductors is the presence of many-body interactions that give rise to broken-symmetry states intertwined with superconductivity. Recent resonant soft X-ray scattering experiments report commensurate 3a0 charge density wave order in infinite-layer nickelates, which has important implications regarding the universal interplay between charge order and superconductivity in both cuprates and nickelates.

Welcome Manan Mehta at ICMAB!

  • Manan Mehta
Hello there, I am Manan and I come from Mumbai, India. At ICMAB, I will be working on the project, OPVStability, as an MSCA DN student under the supervision of Dr. Mariano Campoy-Quiles. I will focus on investigating OPV materials using high-throughput screening methods to improve organic photovoltaic lifetimes. Previously, I completed my Master of Research in Soft Electronic Materials from Imperial College London where I worked on Perovskite-based Memristors, Transistors, and Memtransistors in the Barnes Group. Working on Perovskites truly changes a man. Now towards more organic and greener pastures. My hobbies include football, music, reading & writing (I have my own publication!), mixed martial arts, travelling, and being curious about everything (much to my misfortune).
