The SIESTA methodology and program, first described in 2002, is a simulation paradigm that has allowed for extensive and precise theoretical research in the properties of materials based on first principle electronic-structure methods. Almost two decades later, a new publication details the improvements made to the paradigm and how this new tools can be applied.

As scientific developments get more and more complex, the challenge of communicating any innovation increases. Despite the increasing amount of applications of new materials in day to day life, explaining how they work is not an easy task, especially with younger people, who might not see any of the more advanced concepts in their science classes. Anna May Masnou, Head of the Communication Department at the ICMAB, has written an article at the SOCIEMAT magazine Material-ES about the MATHEROES initiative, which personalizes material properties into superheroes.

Researchers at the ICMAB, UAB and the ALBA Synchrotron, in collaboration with the UB and ICN2, have developed a new technique to locally modify the properties of a metamagnetic material. The method consists in applying local pressure to the surface of the material using nanometric needles and allows a much more easy and local modification than current methods. The research opens the door to a more accurate and precise control of magnetic materials and allows to improve the architecture and capacity of magnetic digital memories.
The Journal of the American Chemical Society (JACS) features in its FRONT COVER the recently published article "Too Persistent to Give Up: Aromaticity in Boron Clusters Survives Radical Structural Changes" by Francesc Teixidor et al. Do you think the balls look like Christmas balls or like billiard balls?
A research recently published on Nature Materials, carried out jointly by the Catalan Institute of Nanoscience and Nanotechnology (ICN2), the Institute of Materials Science of Barcelona (ICMAB), Nanchang University (China) and Chongqing University (China), has demonstrated that light can increase by orders of magnitude the electricity produced by bending (flexoelectricity) in semiconductors. This phenomenon, called photoflexoelectricity, allows a single device to harvest energy from multiple environmental sources.
Teresa Puig appears on the 34th volume of Superconductor Week, a monthly newsletter dedicated to bringing news and analysis about superconductivity to all related parties, from scientists to investors in the industry. Their latest issue covers the breakthrough achieved by the Superconducting Materials Research Group (SUMAN) in the field of growth of YBCO epitaxial films, which was already covered in Nature Communications 11, 334 (2020).
New technologies are frequently supported on innovative functional materials that allow for improvements in performance in order to leave behind the physical limitations of current materials. The economic supplement of La Razón Innovadores talked with 6 expert researchers on the field of materials, amongst which was ICMAB's Director Xavier Obradors, to find more about the future of hardware in advanced technologies.

The relationship between environmental factors and SARS-CoV-2 will shape the ways in which we respond to the virus as the weather changes. It is still soon to have a definitive idea of how it is affected by variables like temperature, humidity, or ultraviolet radiation, but José Vidal-Gancedo has been compiling what we know and developing a comprehensive article on the topic. His findings have been echoing on the media: he first published the article on La Vanguardia, which was followed by an interview on Aquí Cuní on SER Catalunya.
Although the concept of aromaticity in chemistry is something that chemists have in their minds very clearly, they find it very difficult to define. Moreover, among chemists, there are two currents with two distinct points of view: the experimental chemists and the theoretical chemists. What happens when we look at the aromaticity of 3D boron clusters?
The article published in JACS by Pepe Giner et al. in which the international team reports a MOF (metal-organic framework) that can separate biobutanol from the biomass fermentation products has received much attention in the American media, since there is a high demand for gasoline, and one of the research collaborators was from Oregon State University.
With cancer as the second leading cause of death worldwide, investigation on its treatment stays relevant. New mononuclear ruthenium–carboranyl complexes bearing bipyridyl derivatives are being developed for bimodal therapy applications, unifying BNCT (boron neutron capture therapy) and chemotherapy on a single smaller dose and giving a more effective response thanks to a synergistic effect. These complexes are being characterized and tested against melanoma and glioblastoma, and showing successful results so far.
Organic electronic devices with an X-ray sensitivity competitive with the inorganic devices in the market are developed at the Nanomol group at the ICMAB, by Marta Mas-Torrent et al. and published today, May 1, 2020, in Nature Communications.
The article "Efficient blue light emitting materials based on m-carborane-anthracene dyads. Structure, photophysics and bioimaging studies" published in 2019 in Biomaterials Science, by Núñez et al. has been featured recently in UAB Divulga. You can find the text in English, Catalan and Spanish.

An article published in the Journal of Medicinal Chemistry , and with the participation of Elies Molins, shows a new family of molecules with high affinity to join imidazoline receptors, which are altered in the brain of those patients with neurodegenerative diseases such as Alzheimer’s, Parkinson’s and Huntington’s. According to the preclinical study, the merge of these specific ligands to I2 receptors improves cognitive skills and some biomarkers which are indicators of brain neurodegenerative processes in murine models.
Researchers from the Institute of Materials Science of Barcelona (ICMAB-CSIC) have discovered a water stable metal-organic framework (MOF) that allows for the separation of butanol from acetone-butanol-ethanol (ABE) mixtures that are extracted from the fermentation process of biomass feedstock, as part of the standard industrial process to produce biofuels. This new compound, mCB-MOF-1, shows promising results compared to other methodologies or other MOF materials. The study is published in JACS on 27 April 2020.
