ICMAB researchers have designed ultrathin materials that maximize the absorption of light in a large range of the solar spectrum. The followed strategy, low cost and fully scalable, is based on combining the thin layer deposition of semiconductors on metals, and the nanostructuring of the material forming photonic crystals. The obtained superabsorbers materials have many potential applications, especially in the field of photovoltaic energy and photodetection.
This news article, appeared at nanotechweb.org websitee (IOP publishing), features a publication recently published by Agustín Mihi and his team in Advanced Materials "Ultrathin Semiconductor Superabsorbers from the Visible to the Near-Infrared" (Pau Molet, Juan Luis Garcia-Pomar, Cristiano Matricardi, Miquel Garriga, Maria Isabel Alonso and Agustín Mihi).
Nanostructuring a thin layer of the semiconductor germanium using a technique called nanoimprinting lithography can greatly boost the amount of light it absorbs across the visible to near-infrared wavelengths. The broadband absorption comes from the strong interplay between Brewster and photonic crystal modes in the material and the effect could benefit optoelectronics applications such as photovoltaics and telecommunications.
- Xanthinuria is a rare disease caused by the accumulation of xanthine in blood, which can lead to serious pathologies, such as renal failure or gout.
- ICMAB researchers have prepared a novel hybrid graphene-based electrochemical biosensor for the fast and 100 times more sensitive detection of xanthine, with respect to previously reported sensors.
- The study, published in the journal Advanced Materials Interfaces, combines the properties of reduced graphene oxide and those of the organic radicals to prepare next generation, low cost electrochemical biosensors.
A recent publication in Advanced Functional Materials by Dr. Marta Mas-Torrent and her team has been chosen to be highlighted on Advanced Science News website. The group is working on the development of high-performance electrolyte-gated field-effect transistors (EGOFETs), electronic devices capable of working in aqueous environment.
A year in review: this post continues with the series of the most cited articles in every month of 2017. Here we feature the most cited articles of September and October 2017.
ICMAB collaboration at the Digital CSIC journal "CSIC Abierto" about Open Access policies and mandates
The last issue (number 16) of the Digital CSIC journal "CSIC Abierto" includes two interviews with ICMAB's Documentalist and Librarian, Alejandro Santos, and with ICMAB Researcher at the NANOPTO Group, Dr. Mariano Campoy-Quiles. The interviews deal with the Open Access mandates adopted by the funding agencies and the experience at ICMAB on accomplishing these mandates.
The main objectives and results of the EUROTAPES European project are featured in the Catalunya Informació radio program "Som com som: un espai d'innovació i talent" with Purificació Barceló. Prof. Xavier Obradors and Prof. Teresa Puig explain some of the main features of the project:
The August 2017 edition of the Research*EU magazine featured an interesting overview of the ACMOL project, which is working to develop graphene-based spintronics for next-gen molecular electronic devices. This article held that ‘Spintronics, molecular electronics and graphene have a common trait: they are all considered as key enablers in the future of computing beyond the limitations of Moore’s and Kryder’s laws. The ACMOL project is contributing to their joint advancement with proof-of-concept devices.’
Self-assembly of highly-porous crystalline particles into novel photonic materials for sensing applications
A multi-disciplinary collaboration between research centers in Spain and Holland, led by the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and the Institute of Materials Science of Madrid (ICMM-CSIC), in collaboration with the Debye Institute for Nanomaterials Science of Utrecht University and the Institute of Materials Science of Barcelona (ICMAB), has resulted in the formation of highly-porous metal-organic framework particles that spontaneously assemble into well-ordered 3D superstructures that present photonic crystal properties. Published in Nature Chemistry, their discoveries are expected to find applications in the design of novel photonic materials for sensing applications, among others.
ICMAB-CSIC researchers are able, for the first time, to measure the very small amounts of charge generated in piezoelectric materials with an inverse use of the atomic force microscope (AFM). The technique, published in Nature Communications, has been implemented by incorporating a new device to the microscope that allows measuring electric currents one billion times smaller than the ones circulating in an LED.
According to EcoDiario.es, the Institute of Materials Science of Barcelona (ICMAB) increased from 170 to 202 employees from 30 November 2011 to 31 July 2017, which represents an increase of nearly 19 %.
One of the projects of Dr. Anna Laromaine, ICMAB researcher in the Nanoparticles and Nanocomosites Group (NN), is featured on EU Research Digital Magazine. The article focuses on one of her projects involving the synthesis and evaluation of nanoparticles in 3D environments: 3DinvitroNPC.
An article about the research in perovskite appeared in "Televisión Nacional de Honduras" website, citing ICMAB, together with other research centers in Spain, where advanced research in this material is done: "Spain is one of the countries in which research (in the development of perovskite) is more advanced.
Apart from the research group in the Institute of Materials Science in Sevilla, there are many more groups specialized in its study, in the University Jaume I of Castelló, the Institute of Molecular Science (University of Valencia), the Institute of Materials Science of Barcelona (ICMAB-CSIC), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), the University Pablo de Olavide in Sevilla, and the Catalan Institue of Chemical Research (ICIQ)."

We transcribe it here, since some previous ICMAB members participated in the study, which was recently published in PNAS: Emergent chirality in the electric polarization texture of titanate superlattices (Padraic Shafer, Pablo García-Fernández,Pablo Aguado-Puente,Anoop R. Damodaran , Ajay K. Yadav, Christopher T. Nelson, Shang-Lin Hsu, Jacek C. Wojdeł, Jorge Íñiguez, Lane W. Martin, Elke Arenholz, Javier Junquer, and Ramamoorthy Ramesh). DOI: 10.1073/pnas.1711652115.
Researchers from ALBA Synchrotron and from ICMAB have established an enriching and fruitful collaboration over the years, which is proven by the number of publications published together since ALBA received its first users, in 2012.
In 2017, 24 publications appeared in collaboration between both institutions, which represented a 21 % of the ALBA Synchrotron articles.

Since the 1950's, magnetic materials have been used to store all kinds of information. The use of magnetic materials is ideal since they allow you to store information for very long periods of time and, moreover, information is easily accessible through well-known reading methods.
However, when storing sensitive information, easy access to information becomes a drawback rather than an advantage, and that's when hiding information becomes a necessity.
Two Scientific Highlights with the participation of ICMAB researchers are featured in the ALBA Synchrotron Activity Report 2016.
Xavier Obradors, ICMAB Director and Researcher at the Superconducting Materials and Large Scale Nanostrucures (SUMAN) Group, participated in a roundtable "from Lab to Fab" at an ICN2 Severo Ochoa Workshop in June 2017. The roundtable discussion was chaired by ICN2 Business Development Officer, Nadia Pons.
The Catalan universities and research centers have rejected the intervention of the public accounts by the Spanish Ministry of Finance and have denounced that this measure violates the principle of university autonomy.
