PlumX: Predicting the photocurrent–composition dependence in organic solar cells

The continuous development of improved non-fullerene acceptors and deeper knowledge of the fundamental mechanisms governing performance underpin the vertiginous increase in efficiency witnessed by organic photovoltaics. While the influence of parameters like film thickness and morphology are generally understood, what determines the strong dependence of the photocurrent on the donor and acceptor fractions remains elusive.

Nanostructure ITO and Get More of It. Better Performance at Lower Cost

Autores: Manel López,*, Juan Luis Frieiro, Miquel Nuez-Martínez, Martí Pedemonte, Francisco Palacio and Francesc Teixidor,*
Citation: Nanomaterials 202010(10), 1974
DOI: https://doi.org/10.3390/nano10101974
PlumX: Nanostructure ITO and Get More of It. Better Performance at Lower Cost

In this paper, we investigated how different growth conditions (i.e., temperature, growth time, and composition) allows for trading off cost (i.e., In content) and performance of nanostructured indium tin oxide (ITO) for biosensing applications. Next, we compared the behavior of these functionalized nanostructured surfaces obtained in different growth conditions between each other and with a standard thin film as a reference, observing improvements in effective detection area up to two orders of magnitude. This enhanced the biosensor’s sensitivity, with higher detection level, better accuracy and higher reproducibility.

Welcome David at ICMAB!

Nombre y apellidos: David Medina Quiroz

Hey! I am David Medina from Mexico. I am a student of Europhotonics from the EMJMD+ program, that is currently working in the TFM with the Nanopto research group at ICMAB, under the supervision of Dr. Agustin Mihi. My main interest is the plasmonics field, and in this project I will continue working in the pursue of a metamaterial with a high Q-factor originated by plasmonic resonances enhanced by an array structure of plasmonic metamolecules and hopefully, apply it for the fabrication of a plasmon laser (spaser). I am looking forward to this experience and to meet the ICMAB community!

Rapid Thermal Annealing of Double Perovskite Thin Films Formed by Polymer Assisted Deposition

Título : Rapid Thermal Annealing of Double Perovskite Thin Films Formed by Polymer Assisted Deposition
Autores: Hailin Wang, Carlos Frontera, Benjamín Martínez * and Narcís Mestres *
Citation: Materials 202013(21), 4966
DOI: https://doi.org/10.3390/ma13214966
PlumX: Rapid Thermal Annealing of Double Perovskite Thin Films Formed by Polymer Assisted Deposition

The annealing process is an important step common to epitaxial films prepared by chemical solution deposition methods. It is so because the final microstructure of the films can be severely affected by the precise features of the thermal processing. In this work we analyze the structural and magnetic properties of double perovskite La2CoMnO6 and La2NiMnO6 epitaxial thin films prepared by polymer-assisted deposition (PAD) and crystallized by rapid thermal annealing (RTA).

Malignant gliomas are the most common malignant and aggressive primary brain tumors in adults, the prognosis being—especially for glioblastomas—extremely poor. There are no effective treatments yet. However, tyrosine kinase receptor (TKR) inhibitors and boron neutron capture therapy (BNCT), together, have been proposed as future therapeutic strategies. In this sense in our ongoing project of developing new anti-glioblastoma drugs, we identified a sunitinib-carborane hybrid agent, 1, with both in vitro selective cytotoxicity and excellent BNCT-behavior.

PlumX: Organic Polyradicals as Redox Mediators: Effect of Intramolecular Radical Interactions on Their Efficiency

The spin–spin interactions between unpaired electrons in organic (poly)radicals, especially nitroxides, are largely investigated and are of crucial importance for their applications in areas such as organic magnetism, molecular charge transfer, or multiple spin labeling in structural biology. Recently, 2,2,6,6-tetramethylpiperidinyloxyl and polymers functionalized with nitroxides have been described as successful redox mediators in several electrochemical applications; however, the study of spin–spin interaction effect in such an area is absent.

Self‐propelled particles and, in particular, those based on mesoporous silica, have raised considerable interest due to their potential applications in the environmental and biomedical fields thanks to their biocompatibility, tunable surface chemistry and large porosity. Although spherical particles have been widely used to fabricate nano‐ and micromotors, not much attention has been paid to other geometries, such as nanorods.

The combination of light‐emitting diodes (LEDs) and rare earth (RE) phosphors as color‐converting layers comprises the basis of solid‐state lighting. Indeed, most LED lamps include a photoluminescent coating made of phosphor material, i.e., crystalline matrix suitably doped with RE elements, to produce white light from a blue or ultraviolet LED chip.

I am going to do my final degree project (TFG) at ICMAB, under the supervision of Dr. Mariano Campoy and Dr. Bernhard Dörling, relevant to thermoelectric devices composed of carbon nanotubes and polymers (PBTTT). I will be varying their concentrations and working temperatures, in some cases I will use dopants, to obtain the most optimal thermoelectric yield possible. In the future, I would like try combine thermoelectric cells with photovoltaic cells.

PlumX: Metallacarboranes as Photoredox Catalysts in Water

Spin-spiral multiferroics exhibit a magnetoelectric coupling effects, leading to the formation of hybrid domains with inseparably entangled ferroelectric and antiferromagnetic order parameters. Due to this strong magnetoelectric coupling, conceptually advanced ways for controlling antiferromagnetism become possible and it has been reported that electric fields and laser pulses can reversibly switch the antiferromagnetic order.

PlumX: Metallacarboranes as Photoredox Catalysts in Water
Metallacarboranes with the shape of the Greek letter θ, such as [Co(C2B9H11)2], were tested, for the first time, as efficient photoredox catalysts in the oxidation of aromatic and aliphatic alcohols in water. Their efficiency is linked to their high solubility in water, their high oxidizing power (Co4+/3+), and their absence of fluorescence on excitation, among others.

Quasiballistic phonon transport from first principles

Autores: Pol Torres, Miquel Royo, Miquel López-Suárez, Junichiro Shiomi, and Riccardo Rurali
Citation: Phys. Rev. B 102, 144305 – Published 26 October 2020
DOI: https://doi.org/10.1103/PhysRevB.102.144305
PlumX: Quasiballistic phonon transport from first principles
At short length scales phonon transport is ballistic: the thermal resistance of semiconductors and insulators is quantized and length independent. At long length scales, on the other hand, transport is diffusive and resistance arises as a result of the scattering processes experienced by phonons. In many cases of interest, however, these two transport regimes coexist. Here we propose a first-principles approach to treat quasiballistic phonon transport where diffusive and ballistic phonons receive separate theoretical treatments.
