Researchers shared insights into the use of metal forming or nano-coated materials

Researchers shared insights into the use of metal forming or nano-coated materials
Dieter Weise from the Fraunhofer Institute for Machine Tools and Forming Technology IWU and Lukáš Halagačka from CEET and IT4Innovations at VSB – Technical University of Ostrava shared information about the development of modern solar-thermal façade systems and nanostructured thin films with the participants of the December FIP Academy webinar.

"Decentralised renewable energy generation methods are increasingly coming into focus in the current energy transition discourse. Ideally, energy should be converted where it is actually used. The international joint research project FutureFaçade is therefore focusing on the development of an advanced solar-thermal facade system. This is designed to generate energy through the exterior walls of a building, which can then be used directly on site for heating or cooling," explained Weise.

The project is based on a newly developed incremental sheet metal forming process at project partner Fraunhofer IWU. The aim is to achieve a leap in scale in the dimensions of the manufactured parts, enabling the automated production of 3D-formed façade elements that combine technology, functionality and design in equal measure. "This project makes the transition from basic research to application in architecture," added Weise.

In the second part of the webinar, Lukáš Halagačka presented research activities ranging from fundamental research on spintronic lasers and terahertz light emission to application research on the holographic structure fabrications. "All these activities have in common the need to develop, characterize and optimise the thin-film materials used. This process includes several characterisation techniques of optical spectroscopy and ellipsometry, atomic force microscopy, and material and structure optical modelling," said Halagačka.

At the Nanotechnology Centre, CEET, and the IT4Innovations National Supercomputing Center, Halagačka is mainly involved in the development of materials prepared by magnetron sputtering, their optical characterisation, and nanostructure fabrication. "My main focus is on the optimisation of deposition conditions of metals, oxides and nitrides. Therefore, I am using methods of DC and RF magnetron sputtering and evaporation in the inert or reactive environment. To characterise the optical properties of materials and nanostructures, I am mostly using optical spectroscopy and ellipsometry methods. To simulate the optical response of a planar or periodical nanostructure, I am using my own developed parallel code based on the Rigorous Coupled Wave Analysis approach. The same tool is used to fit experimental optical data to achieve a realistic model of the fabricated structures," explained Halagačka.

The next FIP Academy professional online seminar will take place on 2 February 2023.
