Summary of the technology

Contactless method to obtain the thermal conductivity tensor of anisotropic and isotropic samples, enabling the development of smart heat manipulation.


Details of the Technology Offer

Our patented technology is a contactless approach based on frequency-domain thermoreflectance thermometry with a line-shaped (1D) heater geometry, obtained through a focused laser beam, whose intensity distribution is modified using special diffractive optical elements. The technology combines the advantages of contact methods based on line-shaped heater geometries, such as the simplicity in the data analysis and capability to measure anisotropic properties, with the advantages of optical approaches (e.g., speed, contactless, imaging, etc.). As a result, we can obtain the thermal conductivity tensor of bulk materials and films by simply rotating the sample with respect to the line-shaped heater defined by the focused laser.

The Institute of Materials Science of Barcelona​ (ICMAB) is a Severo Ochoa Centre of Excellence research center which beongs to the Consejo Superior de Investigaciones Científicas (CSIC) and is governed by a Foundation board.

The Institute was set up in 1987 and subsequently, in April 1991, the laboratories were opened at the Campus of the Autonomous University of Barcelona (UAB). It is part of the Barcelona Nanotechnology Cluster in Bellaterra.

The aim of the institute is to carry out research aimed at obtaining and characterising materials of industrial interest. Its activities are based on the synthesis, preparation, crystallization and characterisation of functional high-performance materials and nanomaterials, which in some cases have led to the construction of device prototypes based on these materials.

Studies and improvements both of conventional materials, as well as new molecular, supramolecular, magnetic, superconducting and porous materials etc. are being developed through projects and research contracts. There are currently 9 ERC funded projects at ICMAB.

To develop these activities, at present there are 57 permanent staff among researchers and back up personnel together with 80 non-permanent staff divided into eight researgh groups, one general unit service, and one unit of Scientific and Technological Services.

In 2016 the ICMAB reached the 100.000 citations, and it is currently the first centre, among the CSIC centres, in the Nature Index. Each permanent researcher publishes close to 5 articles per year in Journals with a very high impact factor.
