Unexpected soft ferroelectric domain walls

"Our colleagues at ICN2 studied a range of ferroelectrics using atomic force microscopy (AFM) and discovered that 180-degree domain walls – regions separating ferroelectric domains with opposite polarization – are mechanically softer than the surrounding material" says Konstantin Shapovalov, ICMAB researcher and co-author of the now published article in Physical Review X Mechanical Softness of Ferroelectric 180° Domain Walls, in which he contributed with the theoretical interpretation of this unexpected phenomenon.

The challenge of understanding low-gradient magnetic separation

Low-gradient magnetic separation (LGMS) is a complex phenomena with a behaviour so contradictory with classic magnetophoresis models that it was considered to be almost paradoxical. An Editor’s Choice feature article at the Langmuir journal, co-authored by ICMAB Researcher Jordi Faraudo, proposes a unified theoretical framework to understand and control this helpful separation technique.

Practical and versatile micro-patterning for organic electronics and photonics

Scientists have managed to draw at high resolution and speed, local patterns in organic semiconductor films used in optoelectronic and photonic applications. The new method enables the patterning of material characteristics and concomitant final properties, including molecular conformation, orientation, crystallinity and composition. The technique, published with open access in Nature Communications, has also been patented and industrial partners are sought for further co-development.

Cost effective approach for the fabrication of large area metamaterials

Metamaterials have revolutionized the field of photonics because of their exotic optical properties absent in natural materials. Made from the arrangement of subwavelength units, the properties of metamaterials do not derive from their chemical composition but rather from their physical structure. Therefore, properly designing the geometry, size and media involved in a metamaterial, it is possible to engineer the overall electromagnetic response beyond the conventional behaviors.

MATHEROES, or how to make materials science appealing, in Material-ES

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.

Nanoneedles to increase the capacity and robustness of digital memories

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.
