Fluorescent organic nanoparticles (FONs) are emerging as an attractive alternative to the well-established fluorescent inorganic nanoparticles or small organic dyes. Their proper design allows one to obtain biocompatible probes with superior brightness and high photostability, although usually affected by low colloidal stability.

The International Meeting for Chemistry Expoquimia will be hosting the INDUSTRIAL DIALOGUES Webinars, a total of 4 seminars discussing different topics related to the cores of the triennial meeting: circular economy, digitalization, and technology transference. This last topic will be covered by Nora Ventosa, from the Molecular Nanoscience and Organic Materials (NANOMOL) group. 

Researchers from the Nanomol group at the Institute of Materials Science of Barcelona (ICMAB-CSIC), the CIBER-BBN network and the ICTS Nanbiosis U6, and members of the TECNIO technology transfer network ACCIÓ-Generalitat de Catalunya, together with the New Jersey Institute of Technology (NJIT, USA) and the University of Parma (UNIPR, Italy) have developed a new nanomaterial for bioimaging. The results of the study are the result of the TECNIOspring PLUS project co-financed by ACCIÓ and the European Commission.

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.

Ruthenium complexes of carboranyl ligands offer the possibility of dual action (chemo + radiotherapy) that might result in significant clinical benefits. In that frame, we describe herein the development of ruthenium–carboranyl complexes bearing bipyridyl derivatives.

The MSCA IF Project entitled Tuning COPs (Conducting Organic Polymers) with IP Clara Viñas, was selected for publication in the ‘Results in Brief’ section of the European Commission’s CORDIS website, in six languages. The article features the main results of the project. "Tuning COPs" started in October 2017 and finished in October 2019.

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?

Epitaxial ferroelectric HfO₂ films are the most suitable to investigate intrinsic properties of the material and for prototyping emerging devices. Ferroelectric Hf_0.5Zr_0.5O₂(111) films were epitaxially stabilized on La_2/3Sr_1/3MnO₃(001) electrodes.

The researchers from four ICMAB Research Groups will be joining another 35 groups from 14 different universities, as well as research and technology centers, with the objective of boosting the energy sector in Catalunya and turning it into a strong international referent for innovation, at the R+D+I Energy for Society Network (XRE4S). 

When the SARS-CoV-2 virus began to break out in Spain, the Chinese Students and Scholars Association in Barcelona launched a fundraising campaign. Some institutions and people in China contacted them and donated them some masks. Wenchao Duan is a PhD fellow at the ICMAB and member of this Association: "On the premise of respecting their wishes, the Association has donated masks mainly to hospitals, nursing homes, health departments and research institutes in Spain", he says. 

The ICMAB has started this week to resume the scientific activity in the laboratories that were stopped due to the Covid-19 pandemic. This week the Metropolitan Area containing Bellaterra and the UAB Campus has passsed to the advanced phase zero (phase 0.5), so researchers and other workers considered to be "non-essential" can start to return to their workplaces. The return will be at a slow pace, but we are very happy to be able to do so!

Nerea Murugarren, Biochemisry Bachelor's Degree student at the Autonomous University of Barcelona (UAB), has prepared a video entitled "BACTERIA: a nanobiotechnology factory for biomedicine" as part of her Final Degree Project. The idea came from all that she learnt during her stay at the Nanoparticles and Nanocomposites (NN) Group at the ICMAB. 

The initiative "Science in the media" calls for an improvement of society’s scientific knowledge through the use of mass media. It does so through a manifesto signed by several professional, scientific and social organisations, and directed towards the CCMA and the Govern de la Generalitat.

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).

Harvesting environmental energy to generate electricity is a key scientific and technological endeavour of our time. Photovoltaic conversion and electromechanical transduction are two common energy-harvesting mechanisms based on, respectively, semiconducting junctions and piezoelectric insulators.

The Marie Skłodowska-Curie Actions (MSCA) 2020 call for Individual Fellowships (IF) is now open. Through this call, the EU will provide € 328 million to support experienced researchers. Researchers of any nationality and at any stage of their career can apply to implement their research projects in any scientific field. This will be the final call under Horizon 2020. The deadline is 9 Sept 2020.

Due to the ubiquitous presence of lithium‐ion batteries in portable applications, and their implementation in the transportation and large‐scale energy sectors, the future cost and availability of lithium is currently under debate.

We report a study where Car–Parrinello molecular dynamics simulations and variable-temperature (30–300 K) ¹H spin–lattice relaxation time experiments nicely complement each other.

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 May12 initiative is an opportunity for the mathematical community to celebrate women in mathematics. The initiative is supported by several organisations for women in mathematics. The day is chosen because it is the birthdate of Maryam Mirzakhani, an Iranian mathematician at Stanford University, expert in geometry and dynamical systems and Fields Medal awardee. She died from cancer in 2017 with 40 years old. A the ICMAB we want to join this celebration that aims to inspires women and men to pursue their dreams in science and mathematics.

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.

The ICMAB is now a member of SECPHO, a national technological innovation cluster formed by companies, technology centres and research centres. SECPHO is focused on promoting technological unnovation through the application of photonic technologies, or technologies based on light, to all types of sectors of our economy.

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 different occupancy of electronic orbitals, the so-called orbital polarization, is a key parameter determining electric and magnetic properties of materials.

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.
