Towards an all-electrical control of heat flux for zero-power "electronics"

  • Researchers from the Institute of Materials Science of Barcelona (ICMAB-CSIC) and the Luxembourg Institute of Science and Technology (LIST) have shown that thermal conductivity can be tuned by an external applied electric field.
  • If the material is mechanically deformed in a suitable way, the external applied electric field can be much lower to achieve the same thermal response.
  • These advances allow envisaging a truly zero-power analogue of electronics, because phononics circuits would need no power supply.

Published a review on Atomic Layer Deposition of complex oxides!

Atomic Layer Deposition (ALD) is a thin film deposition technique widely used in the synthesis of semiconductor devices and nanomaterials. The main characteristic is its atomic-scale control of the layer thickness and film uniformity. Now, Mariona Coll, researcher at the ICMAB, and Mari Napari, researcher at the University of Southampton, have published a review in the journal APL Materials to describe some of the major achievements and challenges of doped and complex oxides ALD.

Read this interview to Mariona Coll to know more about ALD and its applications!

Lead halide perovskites are not ferroelectric: further research is needed to discover why they are so good for solar cells

  • Perovskites promise to be the next star material for solar cells, but the reason of their high efficiency is still unknown.
  • Researchers at the Institute of Materials Science in Barcelona (ICMAB-CSIC) and the Helmholtz-Zentrum Berlin für Materialien und Energie (Germany) have demonstrated with a new microscopy technique that perovskites are not ferroelectric, as was thought.
  • The new technique, patented by CSIC in 2017, is the direct piezoelectric force microscopy (DPFM) which, for the first time, is used in lead halide perovskite solar cells.

Superconductors instead of copper for the future circular collider (FCC) at CERN

  • The future circular collider (FCC), with a 100 km circumference ring, will extend the research currently being conducted at the Large Hadron Collider (LHC) in the search for new physics.
  • High-temperature superconductors, such as YBCO, are being studied to be used as coating for the FCC ring instead of copper. Researchers have found that these materials outperform copper by a factor of 40, which would greatly enhance the FCC efficiency and provide big energy savings.
  • The Superconducting Materials and Large Scale Nanostructures (SUMAN) group at the ICMAB-CSIC participates in this study as part of a consortium with the ALBA Synchrotron, the IFAE and the UPC.

"Thin-sections, the past serving the future": two articles from Jordi Rius featured in UABDivulga

The studies "Synchrotron tts-µXRD identification of secondary phases in ancient ceramics" published in Heritage Science, and "Breaking Preconceptions: Thin Section Petrography For Ceramic Glaze Microstructures" published in Minerals are now featured in UABDivulga. These two articles, in which researchers from the UAB and the ICMAB have collaborated, refute the common perception of thin-sections as an old-fashioned laboratory preparation and show how this sample format conceived in the 19th century is still in force and can be adapted to the research and the new tools of the 21st century, such as the synchrotron facilities.
