Induced Dipoles and Possible Modulation of Wireless Effects in Implanted Electrodes. Effects of Implanting Insulated Electrodes on an Animal Test to Screen Antidepressant Activity

Título : Induced Dipoles and Possible Modulation of Wireless Effects in Implanted Electrodes. Effects of Implanting Insulated Electrodes on an Animal Test to Screen Antidepressant Activity
Autores: Laura Perez-Caballero, Hector Carceller, Juan Nacher, Vicent Teruel-Marti, Eulalia Pujades, Nieves Casañ-Pastor,* and Esther Berrocoso,*

PlumX: Induced Dipoles and Possible Modulation of Wireless Effects in Implanted Electrodes. Effects of Implanting Insulated Electrodes on an Animal Test to Screen Antidepressant Activity
There is evidence that Deep Brain Stimulation (DBS) produces health benefits in patients even before initiating stimulation. Furthermore, DBS electrode insertion in rat infralimbic cortex (ILC) provokes antidepressant-like effects before stimulation, due to local inflammation and astrogliosis. Consequently, a significant effect of implanting electrodes is suspected. External fields, similar in magnitude to the brain’s endogenous fields, induce electric dipoles in conducting materials, in turn influencing neural cell growth through wireless effects. To elucidate if such dipoles influence depressive-like behavior, without external stimulation, the comparative effect of conducting and insulated electrodes along with the glial response is studied in unstressed rats.

PlumX: Common workflows for computing material properties using different quantum engines
The prediction of material properties based on density-functional theory has become routinely common, thanks, in part, to the steady increase in the number and robustness of available simulation packages. This plurality of codes and methods is both a boon and a burden. While providing great opportunities for cross-verification, these packages adopt different methods, algorithms, and paradigms, making it challenging to choose, master, and efficiently use them. We demonstrate how developing common interfaces for workflows that automatically compute material properties greatly simplifies interoperability and cross-verification.

PlumX: Polarization and Resistive Switching in Epitaxial 2 nm Hf0.5Zr0.5O2 Tunnel Junctions
In the quest for reliable and power-efficient memristive devices, ferroelectric tunnel junctions are being investigated as potential candidates. Complementary metal oxide semiconductor-compatible ferroelectric hafnium oxides are at the forefront. However, in epitaxial tunnel devices with thicknesses around ≈4–6 nm, the relatively high tunnel energy barrier produces a large resistance that challenges their implementation. Here, we show that ferroelectric and electroresistive switching can be observed in ultrathin 2 nm epitaxial Hf0.5Zr0.5O2 (HZO) tunnel junctions in large area capacitors (≈300 μm2).

Coming soon! SOPHOT: Severo Ochoa Workshop on Phononics and Thermal Transport

Date: 2021-10-18

The new workshop on phononics and thermal transport will take place on 18-19 October 2021 from ICMAB and online. Register before 11 October!

Heat transport is becoming increasingly important within the Research Line in Sustainable Energy Conversion and Storage Systems (RL1 at ICMAB).

Besides the fundamental scientific interest, learning how to modulate the heat flow has important applications in conventional electronics (where heat dissipation at the nanoscale is a major issue) or in the design of efficient thermoelectric materials (where materials with low thermal conductivities must be engineered).

Copper and copper oxide nanoparticles (NPs) are industrially important. In particular, Cu-based nanocatalysts find applicability in electrocatalysis and photocatalysis, profiting from the accessible oxidation states of copper and a band gap in the visible region of the Cu2O phase. However, in this case, the fast recombination of the charge carriers compromises the final photocatalytic efficiency.

Over the past 30 years, the engineering of plasmonic resonances at the nanoscale has progressed dramatically, with important contributions in a variety of different fields, including chemistry, physics, biology, engineering, and medicine. However, heavy optical losses related to the use of noble metals for the fabrication of plasmonic structures hindered their application in various settings.

ICMAB joins the 7th edition of the Science by Women programme

A senior African women researcher will develop a research project during a 6-month stay at ICMAB. 

The Fundación Mujeres por África (FMxA)(Women for Africa Foundation) is partnering with the Spanish ‘Severo Ochoa’ and other Centers of Excellence to bring the Science by Women programme to fruition. The project intends to host women researchers from African countries, so they can benefit from these research internships to promote and lead the scientific innovation that contributes to tackling the great challenges faced by African countries through research in health and biomedicine, sustainable agriculture and food security, water, energy and climate change.

Switchable photovoltaic response in hexagonal LuMnO3 single crystals

Título : Switchable photovoltaic response in hexagonal LuMnO3 single crystals
Autores: Yunwei Sheng, Ignasi Fina, Marin Gospodinov, and Josep Fontcuberta
Citation and DOI: Appl. Phys. Lett. 118, 232902 (2021)
DOI: https://doi.org/10.1063/5.0053379
PlumX: Switchable photovoltaic response in hexagonal LuMnO3 single crystals
Hexagonal manganites, such as h-LuMnO3, are ferroelectric with its polar axis along the hexagonal axis and have a narrow electronic bandgap (≈1.5 eV). Using Pt electrodes, h-LuMnO3 single crystals display a strong rectification, characteristic of a Schottky diode, and a large photoresponse. It is found that the short circuit photocurrent density Jsc along the polar axis is modulated (up to 25%) by the direction of the ferroelectric polarization P, leading to a short circuit photocurrent loop that mimics the ferroelectric polarization. However, a non-switchable Jsc persists. Diffusion photocurrent is shown to dominate current-in-plane measurements and contributes to the non-switchable Jsc.

Ordered arrays of metal nanoparticles offer new opportunities to engineer light–matter interactions through the hybridization of Rayleigh anomalies and localized surface plasmons. The generated surface lattice resonances exhibit much higher quality factors compared to those observed in isolated metal nanostructures. Template-induced colloidal self-assembly has already shown a great potential for the scalable fabrication of 2D plasmonic meta-molecule arrays, but the experimental challenge of controlling optical losses within the repeating units has so far prevented this approach to compete with more standard fabrication methods in the production of high-quality factor resonances.
