Summary of the technology

A new device for vacuum sublimation. The sublimator allows the deposition of materials directly onto the desired substrate without using an intermediate surface or solvents, or other intermediate substances for the deposition.


Details of the Technology Offer

Vacuum sublimation methods are used, on one hand, for the purification and recrystallization of molecules, and, on the other hand, to study the reactivity of materials on different substrates.

Current easy-to-use methods deposit crystalline materials in intermediate substrates, needing additional steps to deposit in the desired substrates. The existing direct methods may need ultra-high vacuum sublimation equipment, complex equipment, implying great difficulties in preparing the samples.

The new device allows an easy-to-use direct sublimation in surfaces, opening a wide range of possibilities about the nature of surfaces, including the possibility that the surface is a device on itself. With the new sublimator the distance between the material and the surface can be adjusted and sublimation parameters, such as temperature and pressure, can be optimized and controlled.

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.
