A nanophenomenon that triggers the bone-repair process

Researchers of the ICN2 Oxide Nanophysics Group led by ICREA Prof. Gustau Catalan have resolved one of the great unknowns in bone remodelling: how the cells responsible for forming new bone tissue are called into action. Their work reveals the possible role of an electromechanical phenomenon at the nanoscale, flexoelectricity, not only in stimulating the cell response, but in precisely guiding it throughout the fracture repair process.

Strongly anisotropic spin relaxation observed in graphene when interfaced with transition metal dichalcogenides

Experimentalists of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have found evidence that the spin-orbit coupling induced in graphene by proximity to transition metal dichalcogenides affects electron spins differently depending on their orientation. Published in Nature Physics, this work suggests new approaches to controlling the transport of spin and valley information in future spintronics devices.

Thermal gradients shown to enhance spin transport in graphene

ICN2 researchers have demonstrated that the application of a thermal gradient in spintronic devices can cause spin signal to increase as a result of a novel thermoelectric phenomenon predicted and subsequently observed in graphene. Specifically, the enhanced spin signal is two orders of magnitude larger than anything previously reported for thermal effects in metals. Published in Nature Nanotechnology, these findings push at the frontier of graphene spintronics technologies.

ICN2 researchers compute unprecedented values for spin lifetime anisotropy in graphene

Researchers of the ICN2 Theoretical and Computational Nanoscience Group, led by ICREA Prof. Stephan Roche, have published another paper on spin, this time reporting numerical simulations for spin relaxation in graphene/TMDC heterostructures. Published in Physical Review Letters, their calculations indicate a spin lifetime anisotropy that is orders of magnitude larger than anything observed in graphene until now. Here, lead author Aron Cummings explains the origin of this effect.

100xCiencia2: Co-creating Value in Scientific Research

100xCiencia.2 was held in Alicante yesterday and today. It brought together the vanguard of Spanish research: the Severo Ochoa and María de Maeztu centers of excellence. The meeting was opened by Carmen Vela, Secretary of State for Research, Development and Innovation, and she highlighted the importance of approaching science and business: "Without transfer there is no innovation and without innovation there is no future"

Self-assembly of highly-porous crystalline particles into novel photonic materials for sensing applications

Researchers from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and the Institute of Materials Science of Madrid (ICMM-CSIC) have formed 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.

Strange but true: turning a material upside down can sometimes make it softer

There’s no way that turning a material upside down makes it any softer, right? Wrong! Through the combined effect of two properties inherent to certain types of crystal, flexoelectricity and piezoelectricity, researchers at the ICN2 led by ICREA Prof. Gustau Catalán have found that polar materials can be made more or less resistant to dents when they are turned upside down… or when a voltage is applied to switch their polarisation. Published this week in Advanced Materials, this research points to the future development of “smart mechanical materials” for use in smart coatings and ferroelectric memories.

Hematite-based nanowire structures to enhance solar-to-fuel conversion in photoelectrochemical water splitting

ICN2 researchers led by ICREA Prof. Jordi Arbiol, in collaboration with the IREC and ICIQ, have produced a material for use in photoelectrochemical water splitting that is not only cheaper than existing alternatives, but increases both the efficiency and output of the process. Based on the integration of several materials into a multilayer nanowire structure, the research was featured on the cover of this month’s Energy & Environmental Science.

How graphene can transform brain-computer interfaces

ICN2 group leader ICREA Prof. Jose Antonio Garrido and fellow Graphene Flagship programme coordinator, Prof. Kostas Kostarelos of the University of Manchester, were invited by Advanced Materials to present their vision of the role of graphene in the design of advanced brain-computer interfaces. Published earlier this month, the work entitled “Graphene in the design and engineering of next-generation neural interfaces” outlines the current state-of-the-art in this field, along with the ways graphene is allowing us to overcome some of the obstacles to fully realising the next generation of neural interfaces.

Graphene-based synthetic antiferromagnets and ferrimagnets

A team of researchers from ALBA and the ICN2 have developed novel graphene-based antiferromagnetic multilayer structures featuring robust magnetic properties. These results, published in Nature Communications, demonstrate that single-layer graphene spaced magnetic thin film structures present perpendicular antiferromagnetic coupling together with a number of properties that are well suited for applications.

Severo Ochoa

Funded by MCI AEI

The ICN2 holds immense pride in being a Severo Ochoa Centre of Excellence since 2014. The Severo Ochoa award is Spain's highest recognition that appreciates scientific brilliance and leadership. It represents research centres that rank among the world's best in their respective fields. Additionally, it honours commitment towards generating significant social and business influence.

In 2014, ICN2 was validated as a Severo Ochoa Centre of Excellence, an honour reaffirmed in 2018 and again in 2023 for another quadrannual span. After being awarded this accreditation thrice in succession, we have solidified the accomplishments of the prior programmes and continue broadening and diversifying the ways our work influences the world around us.
